How to become a home inspector

To become a home inspector, start by finding out what your state requires, because licensing ranges from detailed education, exam and insurance rules to no statewide license at all. Then complete approved training, pass any required exam, arrange insurance, and get supervised field experience before you inspect homes on your own. Most new inspectors also set up a small business at the same time, since many work for themselves.
The rest of this guide walks through each step, what it usually involves, and where people tend to get stuck.
What does a home inspector actually do?
A home inspector visits a house, condo or townhome, examines its visible and accessible systems and components, and writes a report on their condition. The US Bureau of Labor Statistics describes home inspectors as examining dwellings and reporting on their structure and overall condition, and notes that while they may spot code issues, they do not have authority to enforce compliance.
In practice, a typical inspection covers:
- Roof, gutters and exterior surfaces
- Grading and drainage around the house
- Foundation and visible structure
- Electrical service, panel and a sample of outlets and fixtures
- Plumbing supply, drains and the water heater
- Heating and cooling equipment
- Attic, insulation and ventilation
- Interior rooms, windows, doors and built-in appliances
An inspector observes and documents. When something looks wrong or falls outside the scope of a general inspection, the inspector recommends evaluation by a qualified specialist, such as a licensed electrician or a structural engineer, rather than diagnosing it.
The work is part field, part desk. BLS notes that home inspectors typically inspect during the day and write reports in the evening, and that self-employed inspectors often work evenings and weekends.
Step 1: Find out what your state requires
This is the first step because everything else depends on it. Requirements vary a lot. Some states set specific pre-license education hours, field training, an exam and minimum insurance. Others have lighter rules or no statewide license.
Two examples from official sources show the range:
- New York requires a course of at least 140 approved hours, 40 of them unpaid field inspections under supervision (or 100 supervised inspections instead), a passing score on the state exam or the National Home Inspector Examination, and liability insurance of $150,000 per occurrence and $500,000 aggregate.
- Texas licenses inspectors through the Texas Real Estate Commission, with education modules, a national and a state exam portion, and proof of insurance before a license issues.
Rules change, so read the current page from your own state's licensing board rather than relying on a training school's summary. Our guide to home inspector licensing by state explains how to read those requirements and what questions to ask.
Step 2: Complete pre-license training
Where your state sets education hours, the course must usually be approved by the state board. Where it doesn't, you still need real training. Clients and agents will expect it, and so will your insurer.
When you compare courses, look for:
| What to check | Why it matters |
|---|---|
| State approval | Unapproved hours may not count toward a license |
| Field component | Classroom knowledge doesn't teach you how to move through a real attic |
| Report writing | The report is the product your client pays for |
| Exam preparation | Useful if your state requires a specific exam |
| Instructor background | Look for experienced inspectors, not only course authors |
| Business basics | Many graduates go straight into self-employment |
Professional associations such as ASHI and InterNACHI publish standards of practice and offer training. Reading a standard of practice early helps you understand what a home inspection does and does not include.
Step 3: Pass the required exam
Many licensing states require an exam. Some accept the National Home Inspector Examination, and some have their own state exam or a state portion on top of a national one. Texas, for example, splits its exam into national and state portions, each with prerequisite modules.
Prepare by studying system by system, not just by memorizing practice questions. Exam questions often describe a condition and ask what it means or what the inspector should recommend, which is the same reasoning you will use in the field.
Step 4: Get insured
Insurance comes up in two ways. Some states require a minimum amount of coverage to license you. Even where they don't, most working inspectors carry:
- Errors and omissions (E&O), for claims that you missed or misreported something
- General liability, for property damage or injury during an inspection
Talk to an insurance broker who works with inspectors before you take your first paid inspection. Ask what's excluded, what the deductible is, and whether the policy requires you to use a pre-inspection agreement. Our post on E&O and general liability basics goes deeper. Treat that as background, not advice for your policy: your insurer and your state's rules decide the details.
Step 5: Build field experience before you go solo
Passing an exam doesn't mean you are ready to inspect a 90-year-old house with a crawl space and three electrical subpanels. The best way to close that gap is supervised time in real homes.
Ways to get it:
- Complete any required supervised or practicum inspections, and do them carefully rather than quickly.
- Ask an experienced local inspector if you can ride along. Offer to carry ladders, take photos or help with setup.
- Practice on the homes of friends and family, writing a full report each time.
- Have an experienced inspector review your practice reports and tell you what's unclear.
- Keep a list of things you weren't sure about, and look each one up before your next inspection.
Many new inspectors underestimate the report. Writing clear findings that a client can act on is a skill of its own. Start with our guide on how to write a home inspection report.
Step 6: Decide how you will work
There are two common routes:
- Join an existing inspection company. You get training, a steady schedule and someone else handling marketing. You trade some income per inspection for that support.
- Start your own business. You keep the full fee but carry every cost and every task: scheduling, agreements, invoicing, marketing and the reports themselves.
Some people start part-time while keeping another income, which lowers the pressure while the business grows. See how to start a home inspection business if you plan to go independent.
How long does it take to become a home inspector?
It depends on your state's requirements and how much time you can commit. A state with a long required course plus supervised field inspections takes longer than one with no license requirement. Exam scheduling, background checks where required, and insurance approval add time. The honest answer is to add up your state's required hours, estimate how many hours a week you can study and train, and leave room for the exam and application to be processed.
Is home inspection a good career?
It suits people who like houses, enjoy solving problems, write clearly and are comfortable talking with clients who may be nervous about a big purchase. It's physical work: attics, crawl spaces, roofs and ladders in heat and cold.
Income varies widely with location, how many inspections you do and what services you offer. BLS publishes pay figures for the broader group of construction and building inspectors, which includes home inspectors. Our guide to what affects a home inspector's income explains how to read those numbers and estimate your own.
Your getting-started checklist
- Read your state licensing board's current requirements
- Choose an approved, field-focused training course
- Read at least one standard of practice end to end
- Pass any required exam
- Get E&O and general liability quotes from a broker who works with inspectors
- Complete supervised inspections and have your reports reviewed
- Decide whether to join a company or start your own
- Set up a way to schedule inspections, collect agreements and deliver reports
When you are ready to run inspections yourself, iSpector inspection reports give you a residential template you can customize, photos attached to findings, and release rules tied to payment and a signed agreement.
Key takeaways
- Start with your state's licensing board, because requirements range from detailed rules to none.
- Choose training with a real field component and report writing, not only exam prep.
- Arrange insurance before your first paid inspection, and confirm details with your insurer.
- Supervised experience and reviewed reports matter more than how fast you get licensed.
- Decide early whether you will join a company or run your own business.
