How to become a home inspector (step by step)

If you're wondering how to become a home inspector, here's the short version: you don't need a college degree, and in much of the country you can start inspecting homes for pay within weeks. But the path looks different depending on where you live, and a handful of states have almost no rules at all.

This guide shows you the whole path, step by step. You'll see what the job actually involves, whether your state requires a license, how long it takes, what it costs to start, and what you can expect to earn. By the end, you'll know if home inspection is the right move for you.

What does a home inspector do?

A home inspector examines a home's major systems and structure, then writes up the condition for a buyer, seller, or owner. A home inspector is a trained professional who evaluates a home's condition and reports problems, but does not make repairs or set the home's price.

Most inspections happen during a sale. The inspector walks the property for two to three hours and checks the roof, foundation, structure, electrical, plumbing, heating and cooling, and more. Then they deliver a written report, often with photos, so the buyer knows what they're really getting.

Many inspectors expand from there. According to the American Society of Home Inspectors (ASHI), inspectors often add services such as radon, mold, termite, pool and spa, well and septic, and even commercial inspections. The more you can inspect, the more you can charge.

How to become a home inspector, step by step

To become a home inspector, complete training, meet your state's licensing rules, pass any required exam, get insured, and start inspecting. Here's the path in six steps.

1. Check your state's rules first. This decides everything else. Some states require approved education and a passing exam score. Others let you start with no formal training at all.
2. Complete a home inspection training course. Even where it isn't required, training teaches you how to spot problems and write a defensible report. Programs run online, in person, or both.
3. Pass the required exam. The National Home Inspector Examination (NHIE) is a national test that many states require for licensure. Your state board will tell you which exam, if any, you need.
4. Get licensed or certified. Where a license is required, you apply through your state. Where it isn't, certification through a group such as ASHI (founded in 1976) or the International Association of Certified Home Inspectors (InterNACHI) signals that you meet a professional standard.
5. Buy your tools and insurance. Expect to carry errors-and-omissions and general liability coverage, plus basic gear like a flashlight, moisture meter, and ladder.
6. Start your business and market yourself. Most inspectors are self-employed and rely on referrals, especially from real estate agents. Your first job is getting those agents to trust you.

Do you need a license to become a home inspector?

Whether you need a license depends entirely on your state. According to the U.S. Bureau of Labor Statistics, license or certification requirements for inspectors vary by state. ASHI puts it plainly: some states require approved education before you can be licensed, while others require no training at all to practice.

That's why step one is always your state board, not a training course. Look up your state's rules, then build your plan around them. And even where the law doesn't require it, getting certified is smart. Buyers and agents trust a credential, and it gives you a standard of practice to point to if a report is ever questioned.

How long does it take, and what does it cost?

Most people become a home inspector in a few weeks to a few months. The timeline depends on your state's required training hours and whether you have to pass an exam before you can work.

Cost works the same way. Plan for four expenses: your training course, any license or exam fees, your tools, and your insurance. In most states the all-in startup cost lands somewhere in the low thousands of dollars. A state with no education requirement can cost far less to enter, but skipping training usually costs you later in missed defects and weaker reports.

How much do home inspectors make?

Home inspectors fall under construction and building inspectors, who earned a median of $72,120 in 2024, according to the U.S. Bureau of Labor Statistics. The lowest-paid 10 percent earned less than $46,560, and the highest-paid 10 percent earned more than $112,320.

Your income depends on volume, your region, and whether you work for a firm or for yourself. The BLS counted about 147,600 inspector jobs in 2024 and projects employment to decline 1 percent from 2024 to 2034. So this isn't a booming field with jobs chasing you. It's a referral business where the inspectors who build trust with agents and clients win the work.

Is becoming a home inspector worth it?

Becoming a home inspector is worth it if you like hands-on, technical work, want a flexible schedule, and are willing to build a referral network. It is not a get-rich-quick path, and flat job growth means you compete on reputation.

If you're weighing it against other property careers, it helps to see them side by side. A home inspector judges a home's condition, a real estate agent helps people buy and sell, and a real estate appraiser estimates market value. Each has a different path in.

Not sure inspection is your lane? It's worth reading how to get into real estate and the pros and cons of becoming a real estate agent before you decide. If the numbers are what you care about, compare what it costs to become a real estate agent, and if analysis is your thing, look at becoming a real estate appraiser.

The bottom line

Becoming a home inspector is one of the faster ways into a property career, as long as you check your state's rules before you spend a dollar. Start with your state board, pick a reputable training course, pass any exam you need, and decide whether inspection or another path fits the way you like to work.
