Does commercial or residential inspection pay better?

Per job, commercial work pays a bigger fee but takes far more hours, and no public source compares what the two earn over a year. In Russ Motyko's view, residential is the steadier income for most new inspectors.

What a commercial inspection is

The commercial version of a home inspection is the property condition assessment, or PCA. The ASTM standard for it is ASTM E2018-24, the Standard Guide for Property Condition Assessments: Baseline Property Condition Assessment Process. ASTM describes it as a framework for assessing the primary improvements at commercial real estate properties.

A PCA under E2018 has more parts than a home inspection:

  • A walk-through survey of the property.
  • Document reviews and research.
  • Interviews, often with the people who manage the building.
  • A property condition report that gives opinions of costs for the suggested remedies.

That last item is the big change for a home inspector. A home inspection report names defects. A PCA puts a cost on fixing them.

Some inspectors work to a different document, the International Standards of Practice for Inspecting Commercial Properties (ComSOP). InterNACHI has discontinued its own commercial certification and points inspectors to the Certified Commercial Property Inspectors Association, whose training follows ComSOP.

What a home inspector license covers

State licenses are written around the house. The home inspection laws of at least 18 states define the job by a home of one to four units, which leaves commercial buildings outside it. A few examples from the state rules:

What the license covers, from the state reference files of October 2026
StateScope of the license
CaliforniaA residential dwelling of one to four units (Business and Professions Code 7195)
MassachusettsA residential building of one to four dwelling units
New YorkOne to four dwelling units, not new construction that has never been lived in
WisconsinResidential property of up to four dwelling units
OregonResidential home inspections of more than one structural component
WashingtonAnyone who examines the condition of a home for a fee
NevadaResidential up to four units and commercial up to 10,000 square feet on the entry certificate; any size on the general and master certificates
VermontReal property structures, with no limit on building type or unit count in the statute

Nevada's rule is in NAC 645D.110 to 645D.130. Elsewhere, a home inspector license does not make someone a commercial inspector. A commercial job also falls outside the rules written for home inspections. Read the state's definition before marketing commercial work.

What the pay data shows

No public survey of commercial inspection fees was found. The figures that do exist are for the whole field or for residential work.

  • The U.S. Bureau of Labor Statistics puts the May 2025 median for construction and building inspectors at $74,690. That group mixes home inspectors with government building inspectors, and BLS wage data leaves out the self-employed.
  • An ASHI Reporter column from October 2024 put the average home inspection fee at $405 and average gross revenue near $123,000 for established inspectors.

Neither splits commercial from residential. Anyone quoting a commercial salary figure should be asked for the source. For the residential numbers in full, see how much home inspectors make.

How the work differs

These comparisons are Russ Motyko's view, not survey results.

The client. A home buyer is making one of the largest purchases of a lifetime and needs the findings explained. Commercial clients are investors, lenders, and portfolio managers who have done many deals. They read a report closely, test the cost opinions against what they know, and care about the method as much as the findings.

The building. Rooftop HVAC units, elevators, fire suppression, large electrical services, and multi-story structure are outside most residential training. Inspectors usually learn them through added coursework and time with someone who already does the work.

The time. A residential job is a few hours on site and a report the same day or the next. A PCA adds document review, interviews, and cost opinions, so one job can fill several days.

The referrals. Residential work comes through real estate agents and past clients. Commercial work comes through brokers and lenders, and that network takes years to build.

Which to start with

For most inspectors in their first three to five years, Russ's advice is residential. The market is larger, the volume is steadier, and the skills come faster. A strong residential reputation is a more reliable path to a solid income than trying to break into commercial work with no track record.

Commercial makes more sense later, added on top of a working residential business. It suits an inspector with a construction management or engineering background, which carries weight with commercial clients. For other ways to widen a residential practice, see which specializations pay.

Questions people ask

Do you need a license to do commercial inspections?

The home inspection laws of at least 18 states cover homes of one to four units, which leaves commercial buildings out. Nevada is an exception: its certificates cover commercial structures. Ask the state board before offering commercial work.

What standard is used for commercial property inspections?

Property condition assessments commonly follow ASTM E2018. The current edition is E2018-24. Some commercial inspectors also work to the International Standards of Practice for Inspecting Commercial Properties, known as ComSOP.

Can a home inspector inspect a five-unit apartment building?

In states that define a home as one to four units, a five-unit building falls outside the license's definition of a home inspection. Check the state's rule before taking the job.

Is a commercial inspection certification required?

No state rule requiring one was found. Credentials such as CCPIA's Certified Commercial Property Inspector are voluntary.
