What else can a home inspector do?

This is the closest move. Building inspectors check construction against the code for a jurisdiction, and the BLS Occupational Outlook Handbook counts home inspectors in the same group. More than a third of the group's jobs, 36%, are in local government.

BLS says inspectors usually need a high school diploma and work experience in a construction trade. Most states and localities also require a license or certification. The International Code Council offers one common route: its Residential Combination Inspector takes four residential certifications, in building, electrical, mechanical, and plumbing. BLS wage data leaves out the self-employed, so the median says more about a government job than about a home inspection business. For that side, see how much home inspectors make.

A property condition assessment, or PCA, is a report on a commercial building's condition. The standard guide for it is ASTM E2018-24. It covers the primary improvements at commercial real estate through a walk-through survey and research, and its report includes opinions of cost for the remedies it suggests.

Russ Motyko's view is that this work comes through a different network. The referrals come from lenders and asset managers, not real estate agents, so an inspector has to meet that side of the market directly. See whether commercial or residential pays better.

Property claims work uses the same eye for damage. BLS notes that property and casualty claims workers have to know housing and construction costs.

Licensing varies by state, according to the BLS page on claims adjusters. On a claim, the job is to document what is there, not to argue for either side.

A HERS Rater inspects and tests a home, usually with a blower door and a duct test, to produce its HERS Index score. Under RESNET's certification standard, a candidate takes a course from an accredited training provider, passes three national tests, and completes five probationary ratings. Two hours of combustion safety field training are also required, all within 15 months.

The Building Performance Institute certifies individuals in roles such as Building Analyst, Energy Auditor, and Healthy Home Evaluator. Its certified professionals page says each certification includes a proctored exam and has to be renewed periodically.

No license makes someone an expert witness. Under Federal Rule of Evidence 702, a witness can be qualified as an expert by knowledge, skill, experience, training, or education. The court decides. In Russ's view, the work often starts when an attorney reads one clear, well-organized report from a sale and calls its author later. That makes report quality the credential, from the first inspection on.

Teaching and mentoring are another path, and each state sets its own rules. See how to become a home inspection instructor or mentor.

Attorneys, lenders, and insurers read reports for a living, and they hire the inspector whose documentation they already trust. Russ's list of what they check comes from the residential work itself:

• Reports that are clear, organized, and hold up when someone else reads them.
• The same documentation habits on every job, not only the big ones.
• A license and credentials anyone can look up.
• A record of completed inspections that can be traced.
• Clear limits on scope: the report documents conditions and does not take sides.

None of this needs a new credential to start. It does take years. In Russ's view, that is why these paths tend to grow out of a residential practice instead of replacing it. A specialty can bridge the two. See home inspector specializations that pay.
