Why Home Inspectors Are Not Suited to Perform Commercial Building Inspections
Introduction
At first glance, residential and commercial building inspections might seem similar—they both involve evaluating the physical condition of a property before a sale or investment, or to provide owners with a professional evaluation of the health of a building. However, beneath the surface lies a world of difference. Commercial building inspections require specialized training, a deep understanding of complex building systems, and a distinct approach aligned with industry standards like ASTM E2018 – Standard Guide for Property Condition Assessments and CCPIA’s Commercial Standards of Practice for inspecting commercial buildings.
Despite these differences, many property buyers, brokers, and lenders make the costly mistake of hiring home inspectors for commercial assets. This article explores why home inspectors are not qualified to perform commercial building inspections, and why only trained commercial inspectors should be trusted with due diligence for income-producing properties.
Why Home Inspectors Are Not Suited to Perform Commercial Building Inspections
1. Different Standards and Purposes: ASTM E2018 vs. Home Inspection Standards
Home inspections are guided by residential standards such as those established by InterNACHI or ASHI, which focus primarily on safety and functionality for homeowners. These reports are meant to help families understand the condition of a dwelling they’ll live in. Home inspection reports are written for private individuals; PCAs are relied upon by institutions (banks, insurance underwriters, private equity, REITs). That shift in audience makes documentation precision far more critical.
By contrast, commercial property inspections follow the ASTM E2018 standard. According to ASTM E2018, a Property Condition Assessment (PCA) is designed to evaluate the physical condition of a property and provide a baseline opinion of probable costs for necessary repairs or replacements over a defined period—typically ten years. ASTM-compliant reports are structured to hold up in litigation or audits; residential reports generally are not.
“This isn’t about whether a water heater works today; it’s about whether the mechanical systems, roof membranes, and structural components will support business operations and cash flow in the years to come. Home inspectors, unless formally trained in PCA methodology, are not equipped to apply this standard,” says Focus Owner, Lance Coffman.
A home inspector’s scope, methods, and reporting formats differ dramatically from those required in commercial practice. ASTM E2018 emphasizes consistency, transparency, and defensibility in the report, while residential standards emphasize homeowner communication and simplicity.
2. Scope and Complexity of Commercial Systems
A commercial building may encompass dozens of systems and components that simply don’t exist in residential construction. Examples include:
HVAC systems: Multi-zone rooftop package units, chillers, and boilers
Electrical: 3-phase power, transformers, sub-panels, and industrial-grade distribution
Plumbing: Fire suppression systems, backflow preventers, and industrial piping
Roofing: Built-up, TPO, EPDM, or modified bitumen systems covering tens of thousands of square feet
Accessibility and code compliance: ADA Title III standards, life-safety requirements, and fire separations
These systems are engineered for commercial performance, longevity, and efficiency—not comfort and convenience. Evaluating them requires both technical competence and real-world experience in commercial building operations. In commercial properties, systems are often interconnected (for example, HVAC integrated with building automation or fire suppression). Home inspectors typically assess standalone systems and may not recognize cross-system failures.
“A home inspector may recognize a leaky faucet or missing GFCI outlet, but assessing the life expectancy of a chiller system or the compliance of an ADA parking layout requires specialized knowledge and training. Commercial inspectors review maintenance logs, service contracts, and warranty records—something not practiced in residential inspections,” says Focus Owner, Lance Coffman.
3. Qualifications and Professional Training
Most home inspectors come from residential backgrounds and may hold state licenses limited to one- to four-family dwellings. Commercial inspectors, by contrast, typically possess certifications from organizations such as the CCPIA (Certified Commercial Property Inspectors Association), which focuses specifically on commercial asset evaluation.
A qualified commercial inspector should:
Understand ASTM E2018 and how to structure a PCA report
Be familiar with commercial construction methods, including steel framing, tilt-up concrete, and masonry bearing systems
Understand building classifications (Assembly, Business, Mercantile, etc.) and how these affect code compliance, fire ratings, and egress design.
Coordinate with specialist consultants, such as structural engineers, roof consultants, or HVAC contractors
Recognize deferred maintenance and capital expenditure risks
Estimate Cost-to-Cure projections accurately for budgeting and negotiation
Translate findings into ROI terms and speak the language of brokers, lenders, and facility managers
Although home inspectors are required to hold certifications in most states, these certifications simply do not involve any of the items listed above. Without this background, a home inspector’s report may omit critical information, underestimate financial liabilities, or fail to communicate findings in a format that lenders and investors can rely on.
“A home inspector may provide a more affordable service, but client’s must understand that price stems from a lack of understanding and experience within the commercial industry. In my professional opinion, saving a few bucks isn’t worth the risk a building owner stands to face in light of this inexperience,” says Focus Owner, Lance Coffman.
4. Differences in Service Agreements: Residential vs. Commercial Contracts
Another overlooked difference between home and commercial inspections lies in the service agreement itself. The inspection contract defines each party’s rights, responsibilities, and limitations—and in the commercial sector, these agreements are far more robust and detailed.
A typical home inspection agreement is a short, standardized form often designed for one- to four-family dwellings. It limits the inspector’s liability to the cost of the inspection (often under $800) and is written primarily to protect the inspector. The scope is narrow, referencing visual-only observations and excluding any responsibility for cost projections, code compliance, or long-term performance.
By contrast, a commercial inspection agreement—especially one based on ASTM E2018 standards—is a negotiated document tailored to the property and client. It clearly defines the scope of services, including what systems will be reviewed, which consultants may be engaged, and what deliverables will be provided (such as PCA reports, ADA evaluations, or Cost-to-Cure projections). These agreements also specify:
Reliance clauses outlining who can use the report (buyers, lenders, investors, etc.)
Limitation of liability appropriate to the project’s value
Indemnification terms that balance protection between client and inspector
Consultant coordination responsibilities for large-scale assets
Commercial agreements often allow multiple parties (e.g., lenders or investors) to rely on the report legally; home inspection contracts usually restrict use to the named buyer only. Commercial agreements allow custom scopes and timeframes; residential agreements are standardized and inflexible.
This level of contractual precision ensures that both parties understand the inspection’s purpose and limitations in a commercial context.
“A home inspector, using a generic residential agreement, may inadvertently expose both themselves and their client to risk. If a dispute arises, that contract may not hold up under commercial litigation—particularly when the property’s value and stakes are significantly higher. Always review the inspection agreement before hiring any inspector, and if the agreement for commercial services is a home inspection agreement, that’s a huge red flag,” says Focus Owner, Lance Coffman.
5. Insurance and Liability Coverage
Another major distinction lies in insurance coverage. Home inspectors typically carry Errors and Omissions (E&O) and General Liability policies designed for residential transactions. These policies often exclude or limit coverage for commercial properties.
A commercial inspection firm, on the other hand, carries higher policy limits, often $2 million or more, and policies specifically covering commercial due diligence activities. This ensures that both the client and inspector are protected if an oversight leads to financial loss.
Commercial inspectors may face liability under lender contracts or investment agreements, while home inspectors generally face small-claims-level disputes.
Commercial firms maintain insurance carriers experienced in real estate and construction litigation; residential carriers may deny coverage for “out-of-scope” work.
Consider this scenario:
A regional investor group purchases a 60,000-square-foot flex warehouse for $4.2 million. The group hires a local home inspector, someone they’ve used for years on residential properties, to “look it over.” The inspector charges $900 and delivers a checklist-style report noting only minor issues.
Six months after closing, tenants begin reporting roof leaks. A professional roofing contractor later discovers widespread membrane deterioration and multiple failed seams, estimating a $225,000 replacement cost. The investor group files a lawsuit against the home inspector for negligence and misrepresentation.
That’s when the real problem emerges. The inspector’s Errors and Omissions insurance specifically excludes commercial properties. His policy carrier denies coverage, leaving him personally liable. With limited assets and no applicable insurance, the inspector cannot pay damages or even cover legal fees.
The Consequences
For the client: The investor group must fund the roof replacement themselves and absorb the loss. Legal action produces only a symbolic judgment, since the inspector has no means to pay. The cost of litigation and downtime adds another $50,000 to their loss.
For the inspector: Without the protection of a commercial E&O policy, the lawsuit leads to personal financial ruin. His business reputation is destroyed, and the case becomes a permanent mark on his record.
This example highlights why insurance coverage tailored to commercial inspections is essential. When a home inspector accepts a commercial job without the proper policy and expertise, both parties are left vulnerable, and in a dispute, nobody wins. This entire scenario could have been avoided had the clients and the inspector had a preemptive discussion about qualifications and insurance coverage.
“Hiring an underinsured home inspector for a multimillion-dollar transaction exposes investors and lenders to unnecessary risk. Simply put: the scale of liability in commercial real estate demands professional-level protection. Always ask an inspector about their insurance coverage, the inspection company should be willing to provide and confirm their level of coverage prior to performing any commercial services. If coverage isn’t suitable to a commercial property, it’s likely the inspector rarely performs commercial inspections,” says Focus Owner, Lance Coffman.
6. The Role of Qualified Subcontractors in Commercial Inspections
Unlike residential inspections, commercial assessments often require the participation of multiple specialized subcontractors or consultants. A single inspector cannot reasonably or efficiently evaluate every system in a large commercial asset—particularly properties exceeding 100,000 square feet or featuring complex systems like fire suppression, elevators, or industrial HVAC.
Experienced commercial inspectors act as project managers, coordinating experts who bring focused knowledge to specific building systems. Typical subcontractors may include:
Structural engineers to review foundations or framing integrity
Roofing consultants to assess membrane systems and estimate remaining service life
HVAC specialists to evaluate chillers, boilers, and control systems
Electrical engineers for load testing and service adequacy
Fire protection experts for life-safety and suppression systems
Why Commercial Inspectors Use Subcontractors
Using qualified subcontractors offers several advantages:
Increased technical depth: Specialized experts deliver more accurate evaluations.
Time efficiency: Multiple professionals can work simultaneously on different systems.
Shared liability: Responsibility for findings is distributed among qualified parties, protecting the client and lead inspector.
Regulatory compliance: Some systems, like elevators or fire suppression, require state-licensed professionals for evaluation.
Enhanced credibility: A well-documented PCA citing licensed experts strengthens lender and investor confidence.
When Home Inspectors Get in Over Their Heads
Home inspectors unfamiliar with this process often lack the network or vetting experience to manage subcontractors effectively. Problems arise when they:
Hire unlicensed or uninsured subcontractors, inadvertently voiding professional liability coverage.
Fail to verify expertise, such as hiring a residential roofer to evaluate a 200,000-square-foot TPO system.
Misinterpret or blindly trust a subcontractor’s findings, lacking the technical knowledge to question inaccuracies or omissions.
Do not integrate subcontractor reports properly into the final PCA, leading to inconsistent or incomplete deliverables.
If an unqualified subcontractor produces an inaccurate or negligent report, and the home inspector includes that information without verification, the inspector may still be held liable. In commercial due diligence, the lead inspector bears responsibility for the accuracy and completeness of all information presented within the final report written by the inspection company, whether the information came from them directly or from a consultant they hired.
Qualified commercial inspectors don’t just collect and pass along reports; they review them critically for consistency and accuracy. Furthermore, commercial inspectors maintain formal records of subcontractor certificates, insurance, and licenses; home inspectors rarely do. In commercial practice, there’s a clear documentation trail showing who performed which evaluations and when, essential for liability defense.
Commercial inspectors who use vetted subcontractors can scale efficiently across multiple properties or geographic regions. This allows a single firm to manage inspections for entire investment portfolios or REIT acquisitions, something a single home inspector could never achieve alone. Consistently partnering with credible experts like engineers, consultants, and contractors positions the lead inspector as a trusted project manager and industry authority rather than a generalist. This strengthens the firm’s brand reputation and referral network among CRE brokers, lenders, and investors.
In short, commercial inspections require not only technical expertise but also management expertise, the ability to coordinate, evaluate, and ensure the quality of others’ work.
“Home inspectors stepping into the commercial arena without this experience risk creating more problems than they solve. Without sufficient commercial experience, home inspectors may not recognize red flags in consultant reports or know how to perform their own due diligence before subcontracting. This can lead to cascading liability, project delays, and significant reputational damage,” says Focus Owner, Lance Coffman.
7. Understanding the Client’s Needs
Residential clients are typically homeowners concerned about safety, comfort, and repair costs. Commercial clients like buyers, sellers, brokers, lenders, and REITs are businesspeople making investment decisions based on return on investment (ROI) and asset performance. Commercial inspectors evaluate how building issues affect business operations and tenant retention, something a home inspector doesn’t consider.
A commercial inspector understands this mindset. Their report must answer questions such as:
What deferred maintenance issues could affect cash flow?
What are the projected capital expenditures over the next 10 years?
Does the property comply with ADA standards, and what is the financial impact if it doesn’t?
Are there any life-safety or code compliance risks that could impede operations or occupancy?
“Home inspectors are not trained to approach inspections from a business perspective. Their focus is on occupant comfort and residential safety, not on investment performance or asset management. At Focus, we recognize that our clients operate businesses within complex commercial assets that must be managed strategically to ensure uninterrupted operations and financial stability, even when unexpected property-related expenses arise,” says Focus Owner, Lance Coffman.
8. The PCA Report: More Than a Checklist
A Property Condition Assessment (PCA) report is a sophisticated document. According to ASTM E2018, a compliant PCA includes:
Executive Summary – key findings and recommendations
Description of Property and Systems – structure, envelope, mechanical, and electrical
Opinions of Cost – immediate repairs and 10-year capital reserves
Photographs and supporting documentation
Specialty reports – structural, HVAC, or roofing evaluations, if applicable
This structure ensures that all stakeholders, brokers, lenders, and asset managers can make informed decisions.
By contrast, residential reports often use software-generated checklists designed for homeowners. They may flag minor issues like loose doorknobs but fail to quantify financial impact, which is the cornerstone of commercial decision-making.
“A PCA isn’t about “passing or failing” a building; it’s about risk management and cost forecasting, concepts outside the residential inspection scope. PCA reports support a wide variety of commercial processes, like appraisal, financing, and property maintenance. Residential reports serve only the immediate buyer and fail to focus on the scope of work a comemrcial client needs to protect their asset,” says Focus Owner, Lance Coffman.
9. ADA and Accessibility Compliance
Commercial properties open to the public must comply with the Americans with Disabilities Act (ADA). ADA compliance reviews are often a key component of a commercial property inspection, ensuring that parking areas, restrooms, signage, and entrances meet accessibility standards. ADA non-compliance can lead not only to fines but to private lawsuits with mandatory attorney’s fees, far more serious than a code violation on a residence.
Real Life Example: The Expo Square ADA Case in Tulsa, Oklahoma
A few years ago, the U.S. Department of Justice investigated a complaint about parking accessibility at Expo Square, home of the Tulsa State Fair. The complaint alleged that the fairgrounds didn’t have enough accessible parking spaces near major event buildings, especially the QuikTrip Center.
Rather than go through a lawsuit, Expo Square reached a settlement with the Department of Justice. The agreement required the fairgrounds to bring their parking areas and transportation services into compliance with the Americans with Disabilities Act (ADA).
Within six months, Expo Square had to redesign and stripe accessible parking spaces throughout the fairgrounds, ensuring the correct number of standard and van-accessible spaces were available. Each space had to meet ADA standards for width, slope, signage, and route access. For any lots where compliance wasn’t feasible due to terrain, Expo Square had to post clear signs directing visitors to nearby accessible parking areas.
In addition to parking, the agreement required the fairgrounds to create a written plan ensuring that people with disabilities could use shuttle or transportation services during large events. The Department of Justice reserved the right to review the plans, inspect the site, and verify compliance.
The agreement lasted for three years and served as a reminder that ADA compliance isn’t optional—it’s a continuing responsibility for public venues and event operators. Regular ADA inspections help identify accessibility gaps before complaints or legal actions arise, protecting both visitors and property owners.
Engaging a qualified commercial inspector to conduct an ADA inspection allows property owners to identify accessibility deficiencies before they lead to complaints or enforcement actions. This preventive approach helps avoid the time and expense often associated with federal investigations or settlements, such as those brought by the Department of Justice, while ensuring the property meets its legal obligations under the ADA.
“Home inspectors do not receive ADA training. Commercial inspectors not only identify violations but can also quantify the cost to bring the property into compliance, a critical and useful tool for buyers and owners of commercial properties who need to bring properties compliant and avoid potential litigation, fines, and investigations,” says Focus Owner, Lance Coffman.
10. Cost-to-Cure Reporting: Financial Forecasting for Investors
In commercial real estate, the question isn’t just “What’s broken?”—it’s “How much will it cost to operate this asset over time?”
Commercial inspection firms often prepare a Cost-to-Cure Report, a 10-year projection of anticipated repairs and replacements based on the property’s current condition. This report allows clients to forecast capital expenditures, negotiate pricing, and plan for ownership costs. Plus, Cost-to-Cure data feeds into capital reserve studies, loan underwriting, and asset lifecycle budgeting. Lenders and buyers use Cost-to-Cure estimates to renegotiate purchase price or loan terms; home inspectors’ reports cannot serve this purpose.
According to one source, replacement of a TPO roof measuring 100,000-square-foot and nearing the end of its service life, can have an estimated replacement cost of over $500,000. A Cost-to-Cure projection helps buyers plan for this expense, potentially leading to renegotiation of the purchase price.
“Home inspectors rarely provide this level of financial analysis. Without it, clients are left without a roadmap for future expenses, undermining the entire purpose of due diligence,” says Focus Owner, Lance Coffman.
11. Report Presentation and Professional Deliverables
Professional Property Condition Reports (PCRs) are structured for financial decision-making. They include clear tables, life-cycle projections, and cost summaries—often in spreadsheet-ready formats that can be easily integrated into asset management or underwriting software. The structure is deliberate: it translates technical findings into usable financial data, enabling decision-makers to act quickly and confidently.
Home inspection reports, while informative for homeowners, are visually and structurally simplistic. They may contain irrelevant residential commentary, generic boilerplate text, and lack cost quantification. For buyers, owners, brokers, and lenders, this makes them nearly unusable and downright unsuitable for underwriting or investment analysis.
Commercial inspection firms, by contrast, deliver reports designed to communicate with multiple professional audiences simultaneously, from property managers and brokers to lenders, appraisers, and equity partners. A well-crafted PCA or Cost-to-Cure report not only describes deficiencies but contextualizes their financial impact, identifies urgency levels, and groups items by repair category or time frame. This hierarchy helps clients prioritize capital projects and distinguish between immediate repairs and long-term investments.
A typical ASTM E2018 compliant report may include:
Executive Summary – Key findings, immediate concerns, and total projected costs summarized for quick decision-making.
Property Description Section – Details on the asset’s age, size, use type, and construction methods.
Systems and Components Analysis – Individual narratives and photos for roofing, structure, envelope, mechanical, electrical, and plumbing systems.
Opinions of Cost Tables – Segregated line items for immediate repairs, short-term maintenance, and 10-year capital reserves, often provided in Excel format.
Deferred Maintenance Log – Documentation of items that require attention to maintain operational efficiency.
Photographic Appendix – Labeled, high-resolution photographs linked to specific deficiencies or reference points.
Consultant Reports – Attachments from specialists such as roofing consultants, HVAC engineers, or ADA assessors, integrated into the main report.
These deliverables are not aesthetic choices; they are industry expectations. Commercial inspection firms use specialized software and formatting tools that align with lender and investor standards, ensuring that reports can be cross-referenced, audited, and imported directly into financial models. A narrative-style home inspection report, even one that is technically accurate, undermines confidence, delays decision-making, and often forces clients to commission a second, ASTM-compliant assessment at additional cost.
“The quality of presentation of our PCA reflects the credibility and accountability of our inspection firm. A clear, data-rich report demonstrates professionalism, transparency, and respect for the magnitude of our client’s investment,” says Focus Owner, Lance Coffman.
12. Compliance with Lender and Investor Requirements
In commercial real estate transactions, due diligence documentation must align with lender and investor expectations. Many lending institutions, particularly SBA, CMBS, HUD, and private equity firms, require that buyers obtain an ASTM E2018–compliant Property Condition Assessment (PCA) as part of the underwriting package. This document serves as a financial risk evaluation tool, not just a building summary. A residential-style inspection report, no matter how detailed, does not satisfy these requirements and can delay financing or even jeopardize loan approval.
Lenders and institutional investors rely on PCA reports to validate collateral value. The PCA provides an independent, standardized assessment of the property’s condition and future capital needs, allowing financial underwriters to incorporate repair and replacement costs into debt-service modeling and reserve planning. These reports are designed for review, audit, and cross-referencing, they are formatted for institutional workflows, not consumer reading. Home inspection reports, on the other hand, cannot be “relied upon” by third parties because they lack formal reliance language, standardized cost opinions, or professional certification under ASTM guidelines.
In fact, many loan commitment letters and participation agreements explicitly require that a PCA be performed by a qualified commercial inspector or licensed professional engineer, and that the resulting report conform to ASTM E2018. Substituting a residential report can trigger additional lender reviews, delay closing, or require the client to pay for a second, compliant assessment.
Beyond lenders, investors, brokers, and REIT asset managers also depend on PCA deliverables to support acquisition modeling and risk analysis. A well-prepared PCA, complete with 10-year cost forecasting and ADA findings, allows investors to forecast future capital needs accurately, justify purchase price adjustments, and negotiate seller credits or maintenance concessions.
For brokers and buyer representatives, a CCPIA- or ASTM-trained inspector’s PCA provides negotiation leverage and ensures that the transaction remains compliant with institutional due diligence standards. For lenders, it delivers defensible documentation that supports loan security. And for portfolio owners, it creates consistency across multiple assets, simplifying long-term financial planning and facility management.
“When viewed from the standpoint of financial compliance, the choice is clear: in order to protect a multimillion-dollar investment, clients must avoid choosing a home inspector to perform vital commercial inspections,” says Focus Owner, Lance Coffman.
13. Liability and Risk Management
When millions of dollars are on the line, due diligence must be defensible. A commercial inspection report should not only be accurate, but it must withstand legal, contractual, and financial scrutiny long after the transaction has closed. Lenders, attorneys, and insurance carriers all expect that the inspection process and resulting documentation meet industry standards such as ASTM E2018.
Home inspectors who operate outside their licensed scope expose both themselves and their clients to serious legal and financial risks. Courts have repeatedly ruled that performing services beyond one’s qualifications can constitute professional negligence or misrepresentation, leaving the inspector personally liable. For clients, this means that recovery options are limited if the inspector’s insurance carrier denies coverage or the report is deemed noncompliant.
By contrast, professional commercial inspectors proactively mitigate risk through robust controls, including detailed service agreements, well-defined scopes of work, reliance language, and project-specific insurance coverage that matches the value and complexity of the asset. They maintain clear documentation trails, coordinate with licensed consultants where necessary, and deliver reports that can withstand audit or litigation if a dispute arises.
“Risk management in commercial due diligence isn’t an afterthought; it’s a core component of professional practice. A home inspector may produce a report; a commercial inspector produces a defensible record,” says Focus Owner, Lance Coffman.
14. The Professional Edge of a Commercial Inspection Firm
Commercial inspectors operate as trusted advisors, not merely technicians with checklists. Their expertise extends beyond identifying physical deficiencies to helping clients make strategic, financially sound decisions about acquisition, ownership, and long-term asset performance.
A qualified commercial inspector’s role often includes:
Consulting on deferred maintenance budgets to prevent operational disruptions and unplanned capital expenditures.
Coordinating environmental, structural, and engineering reports to deliver a unified due diligence package.
Advising on ADA compliance strategies that reduce legal exposure and improve property marketability.
Supporting acquisition teams during negotiations, providing cost-backed leverage for price adjustments or repair credits.
Communicating findings in boardroom-ready reports that translate technical data into actionable business intelligence.
For portfolio owners, asset managers, and REITs, partnering with a professional commercial inspection firm brings consistency, credibility, and scalability across multiple properties and markets. It allows decision-makers to track performance, compare costs, and manage risk at a portfolio level, something a residential inspector is neither equipped nor insured to do.
“Commercial inspectors advise on more than defects within a building, which is where the training for home inspectors typically runs out,” says Focus Owner, Lance Coffman.
15. Real-World Consequences of Hiring the Wrong Inspector
The risks of hiring a home inspector for a commercial property extend far beyond missed defects, they can trigger financial losses, legal disputes, and long-term operational setbacks. In commercial real estate, even a small oversight can escalate into six-figure consequences.
examples of what can go wrong when a home inspector is hire to do the work of a qualified commercial building inspector:
Case 1: Misidentified HVAC systems
A regional investment group hired a residential home inspector to evaluate a 12,000-square-foot mixed-use commercial property, but due to limited experience with commercial systems, the inspector failed to identify major HVAC deficiencies. The report simply stated that the units “appeared operational,” without noting that the rooftop systems were at the end of their service life, the makeup air unit was unbalanced, or that no performance testing or maintenance records had been reviewed. Within six months of purchase, tenants reported comfort issues, and a commercial contractor later found cracked heat exchangers, a failed compressor, and ventilation code violations, costing the buyers over $42,000 in repairs and lost rent. The case underscores the risks of using a home inspector for commercial properties, where complex HVAC systems require specialized knowledge, detailed documentation, and a commercial inspection standard to protect clients’ investments.
Case 2: Incomplete Roof Assessment
A private investor engaged a residential inspector to assess a 50,000-square-foot warehouse prior to acquisition. The inspector declined to access the roof, citing “roof not inspected due to height,” and provided no drone imagery or alternate evaluation method. After closing, leaks appeared throughout the warehouse during the first major rain event. A follow-up PCA conducted by a qualified commercial firm revealed widespread ponding water, deteriorated membrane seams, and multiple areas of saturated insulation. The roof replacement and related interior damage totaled over $185,000, far exceeding what a proper commercial roof assessment would have cost. The investor’s frustration grew when the inspector’s report was deemed inadmissible by his insurance carrier due to its residential format and lack of ASTM compliance.
Case 3: ADA Non-Compliance
A medical office buyer relied on a home inspector’s report that made no mention of ADA accessibility. After purchase, a patient using a wheelchair filed a formal complaint with the Department of Justice for non-compliant parking spaces, door widths, and restroom layouts. The subsequent remediation work—including restriping, door replacement, and restroom renovation—cost nearly $60,000, not including legal fees and lost occupancy time. A commercial inspector trained in ADA compliance would have identified the deficiencies upfront, allowing the buyer to negotiate repairs or credits before closing.
Case 4: Insurance Denial and Legal Exposure
In another instance, a small-town inspector accepted a light industrial inspection without realizing his Errors and Omissions (E&O) policy excluded commercial properties. When structural deficiencies were discovered post-closing, including corroded steel framing and an unpermitted mezzanine addition, the buyer sought restitution. The insurer denied the claim on the basis that the work was outside the inspector’s covered scope. The court ruled in the buyer’s favor, but the inspector lacked sufficient assets to satisfy the judgment—leaving the client with a six-figure loss and no avenue for recovery. This example highlights the cascading consequences of unqualified inspection work and inadequate professional coverage.
Each of these outcomes could have been avoided with a qualified commercial inspection firm following ASTM E2018 and CCPIA best practices. Commercial inspectors not only recognize technical deficiencies but also provide the documentation, cost forecasting, and legal defensibility that institutional clients depend on to make informed, risk-managed decisions.
“Commercial clients stand to lose their livelihoods if they hire the wrong professional to conduct inspections of their commercial property,” says Focus Owner, Lance Coffman.
Final Takeaway: The Right Inspector Protects the Investment
Commercial real estate isn’t a place for guesswork or residential shortcuts. The stakes are higher, the systems are more complex, and the financial consequences of an inaccurate report can be severe. Only a qualified commercial inspector trained in ASTM E2018 standards, backed by commercial insurance, and experienced in property condition analysis can deliver the depth of evaluation that investors, lenders, and brokers depend on.
“At Focus Building Inspections, our purpose is simple: to protect our clients’ investments through precision, transparency, and unmatched industry expertise. The right inspection doesn’t just identify issues, it provides the insight, documentation, and foresight needed to make confident decision makers out of every property owner,” says Focus Owner, Lance Coffman.
15 Solid Reason Why Home Inspectors Should NEVER be Hired for Commercial Inspections
In Summary: What You’ve Learned
Different Standards and Purposes: Home inspectors follow residential standards like InterNACHI or ASHI, while commercial inspections must meet ASTM E2018 requirements designed for institutional reliance and legal defensibility.
Scope and Complexity of Commercial Systems: Commercial properties contain complex, interconnected systems that require specialized technical knowledge far beyond typical residential experience.
Qualifications and Professional Training: Only inspectors trained in ASTM E2018 and certified by organizations like CCPIA are qualified to evaluate commercial assets and communicate findings in investor-ready formats.
Differences in Service Agreements: Commercial inspection contracts are customized, detailed, and legally robust, unlike standardized residential agreements that can’t support high-value transactions.
Insurance and Liability Coverage: Residential E&O policies rarely cover commercial work, leaving both clients and inspectors exposed to major financial risk if problems arise.
The Role of Qualified Subcontractors: Commercial inspectors coordinate licensed specialists for complex systems, while home inspectors often lack the network or management skill to do so effectively.
Understanding the Client’s Needs: Commercial clients make ROI-based decisions, so inspectors must evaluate how property conditions affect operations and investment performance.
The PCA Report: ASTM-compliant PCA reports quantify risk and long-term costs, whereas residential checklists focus only on immediate household issues.
ADA and Accessibility Compliance: Commercial inspectors assess ADA compliance and associated financial impacts—areas beyond residential inspectors’ training.
Cost-to-Cure Reporting: Commercial inspections include financial forecasting for repairs and replacements, helping investors plan and negotiate intelligently.
Report Presentation and Professional Deliverables: Commercial reports are data-driven and formatted for financial stakeholders, unlike homeowner-oriented residential templates.
Compliance with Lender and Investor Requirements: Lenders and investors require ASTM E2018-compliant PCAs—residential-style reports fail to meet due diligence standards.
Liability and Risk Management: Performing commercial inspections without proper expertise and coverage exposes both inspector and client to significant legal and financial risk.
The Professional Edge of a Commercial Inspection Firm: True commercial inspectors act as consultants and advisors, helping clients strategize maintenance, compliance, and acquisition.
Real-World Consequences: Hiring an unqualified home inspector for a commercial property can lead to costly oversights, legal disputes, and financial losses.
