How to start a home inspection business: training, agreements and agents
To start a home inspection business, you need whatever license or registration your state requires (rules vary widely, and some states have none), solid training in a recognized standard of practice, errors and omissions and general liability insurance, a signed inspection agreement before every inspection, and a way to deliver a clear report quickly. Most new inspectors build the business through real estate agent referrals and direct-to-buyer marketing, so reputation and turnaround time matter from the very first job.
Home inspection is different from most service businesses. You aren't fixing anything. Your product is a professional opinion delivered in a report, often under time pressure from a real estate deadline. That changes what you need to get right.
Does your state license home inspectors?
This is the first question, and the answer depends entirely on where you work. Many states license or register home inspectors, with requirements that can include classroom hours, field training or supervised inspections, a national or state exam, insurance and continuing education. Some states have no state-level requirements at all. A few have rules about who may perform related services or how reports must be written.
Go straight to the source: your state's home inspector licensing board or the agency that oversees real estate professionals. Ask:
- Is a license or registration required to perform home inspections for a fee?
- What training hours, exams and supervised inspections are required?
- What insurance must I carry, and in what amounts?
- Is there a required standard of practice or report content?
- What continuing education is required to renew?
Even where no license is required, buyers, agents and lenders expect real training. Our contractor licensing and insurance starting point covers general questions for licensing boards.
How should you train?
Good training covers two things: how buildings work and fail, and how to communicate findings.
- Choose a recognized standard of practice. National associations such as ASHI and InterNACHI publish standards that define what an inspection covers. Some states have their own. Know yours thoroughly, because it defines what you are responsible for.
- Do ride-alongs with experienced inspectors if you can. Watching how a veteran moves through a house, and how they talk to buyers, is hard to learn from a course.
- Practice on real homes. Inspect friends' and family members' homes and write full reports. Compare your findings with what an experienced inspector would note.
- Learn report writing. A clear, well-organized report that separates safety issues from maintenance items is what clients and agents remember.
What insurance does a home inspector need?
Talk to an agent who insures home inspectors. Common coverage includes:
- Errors and omissions (E&O), which addresses claims that you missed something in an inspection. Some states require it.
- General liability, which covers damage you cause during an inspection, such as a cracked ceiling tile or a broken window latch.
- Commercial auto, for driving to inspections.
Ask your agent and your attorney how your inspection agreement and your insurance work together.
Why is the inspection agreement so important?
A pre-inspection agreement sets out the scope of the inspection, what it does and doesn't include, the fee and other terms. Many inspectors require it to be signed before the inspection begins, and some states have rules about agreement content or timing.
Have an attorney familiar with your state write or review your agreement. Then build a habit:
- Send the agreement as soon as the inspection is booked.
- Don't start the inspection until it's signed.
- Keep the signed copy with the inspection record.
This is also a good moment to get paid. Many inspectors collect the fee at booking or require payment before the report is released.
What tools do you need?
A practical starter kit:
- Ladders: a telescoping or articulating ladder that fits in your vehicle
- A strong flashlight and a backup
- Moisture meter
- Electrical outlet tester and a non-contact voltage tester
- Screwdrivers for removing panel covers, if your standard of practice includes it
- Thermometer for checking supply and return air temperatures
- Camera or a phone with a good camera, and plenty of storage
- Coveralls, knee pads, gloves, respirator or mask for attics and crawl spaces
Many inspectors add an infrared camera and a drone for roofs later. Learn their limits before you report on what they show.
Which add-on services should you offer?
Ancillary services can add meaningful revenue to each inspection, but several carry their own licensing or certification rules.
| Service | What it involves | Check before offering |
|---|---|---|
| Radon testing | Placing and retrieving a test device | Some states require radon testing certification or licensing |
| Wood-destroying organism (termite) reports | Inspecting for insect damage | Often regulated separately, sometimes through pest control licensing |
| Sewer scope | Camera inspection of the sewer line | Equipment cost, training |
| Mold sampling | Air or surface samples sent to a lab | Some states regulate mold assessment |
| Pool and spa | Visual inspection of equipment | Training |
| Infrared scans | Thermal imaging for moisture or insulation | Training, clear limits in your report |
Start with one or two that fit your market, and confirm the rules for each in your state.
How should you price inspections?
Most inspectors set a base price by the home's square footage, then adjust for factors that change the work:
- Age of the home, since older homes usually take longer
- Crawl spaces, multiple HVAC systems or detached structures
- Distance from your base
- Add-on services
To set your base prices, time your inspections and report writing for different home sizes, add your drive time, and work out what each hour needs to earn to cover insurance, tools, software, association dues, continuing education, marketing and your own pay. Then compare with local inspectors. Being the cheapest is rarely a good strategy in a field where clients are buying confidence.
How do you deliver reports fast?
Buyers usually have a limited inspection period in their contract. Agents notice which inspectors deliver clear reports quickly.
- Use a report template with your standard sections and comments, so you aren't writing from scratch.
- Capture photos and notes on site, in the template, as you go.
- Aim to deliver the same day or within a day, and say so when booking.
- Lead with a short summary of the most important findings.
How do you build referrals from real estate agents?
Agents are a major referral source, which raises a real question of independence. Your duty is to your client. Inspectors who are known for clear, fair, well-explained reports, rather than for being "easy," tend to earn both buyers' and agents' trust. Some states have rules on relationships between inspectors and agents, so check yours.
Practical ways to build relationships:
- Offer to present at real estate office meetings on common inspection findings.
- Make scheduling easy: online booking, fast confirmations, flexible times.
- Communicate well with everyone involved, within what your client authorizes.
- Ask satisfied buyers for reviews. Many buyers search for inspectors themselves.
