Home Inspector License vs. Certification: A Complete Guide

Home Inspection Industry July 13, 2025

Starting a career in home inspection and are wondering how you can further your qualifications?

One of the first things to consider is to determine the difference between a home inspector license and industry certifications. Is there more than one license? If so, which ones are necessary to kickstart your career as a qualified home inspector? For the home inspector certification process, what’s available and why seek further education?

This guide offers insights into the differences between obtaining a home inspector license and certification, as well as guidance on establishing a solid foundation for your career. 

There Are Home Inspection Opportunities Across the U.S.

It is estimated that there are over 10,500 home inspectors in the United States, with more than 80% likely working for private companies. The opportunities are spread across the country. The states with high concentrations of home inspectors include California, Florida, New York, and Texas. The average salary varies across states, and so do career requirements. 

Do You Need a Home Inspector License?

In the United States, certain states, like Florida, require a home inspector license. Other states, such as California and Colorado, do not. See a more comprehensive list of home inspector license requirements by state.

In states that do not require a home inspector’s license, it is often crucial that you become certified to establish credibility with agents and clients in your community.

So, what is a home inspection license?

To get a home inspection license, you must receive a credential issued by a government or regulatory body authorizing you to perform inspections for a fee. This license indicates that you have met specific requirements regarding education, training, and examination. In essence, the license showcases your competence as a home inspector. 

Certification is typically voluntary in all states. However, licensing is mandatory in certain states and areas. In these states, operating without a license could result in legal consequences and an inability to work as a home inspector.

How Does Home Inspector Licensing Compare to Certification?

While licensing and certification are related, they do differ. A home inspector licence vs. certification comparison helps you understand those differences. 

A license is a formal permission granted by a regulatory body or government agency, allowing you to work as an inspector. Its purpose is to ensure you adhere to specific standards.

Certification, on the other hand, is proof you meet specific educational or training requirements. A private organization often sets these requirements. Once you are a certified home inspector, you become more credible as a professional.

While not usually necessary, getting certified makes you more reputable as a home inspector. This is because obtaining a certification can mean you exceed minimum licensing requirements. 

Home Inspector License vs. Certification: What’s Involved

Some states mandate specific training programs and examinations. One is the National Home Inspector Exam (NHIE), which many states use as a benchmark for licensing. Here are some tips to help you pass. You may also need to get insurance coverage to operate in your state. 

Certification is highly recommended in states without licensing. Two organizations that offer such certifications are the International Association of Certified Home Inspectors (InterNACHI) and the American Society of Home Inspectors (ASHI). Depending on the certification program you choose, you may need to complete training, pass an exam, and gain practical experience through field training. 

Your coursework will cover a range of topics, including exterior, insulation, and plumbing, especially if you’re seeking specialized training. You may also want to seek business and marketing training to gain a competitive edge. 

Select your state to get started.

What’s Next? How to Become a Certified Home Inspector

If you have yet to take the first step or want to progress in your career as a home inspector, consider the following steps. 

  • Check state requirements, including licensing and certification requirements. In addition to passing the NHIE or a similar state-specific exam, you may need to complete a certain number of training hours or gain field experience. 
  • Enroll in a state-approved home inspector training program, which may combine online and in-person training. Common topics covered include HVAC, structural systems, and electrical systems. Additionally, consider specialized training if you want to offer services such as radon testing and well flow tests
  • Obtain insurance, such as errors and omissions (E&O) insurance and other professional insurance policies. This requirement will vary from state to state. 
  • If necessary, apply for your license. You will need to show proof of exam results, training, and insurance. You may also need to provide additional documentation. In addition, some states will require a set number of supervised inspections or hours under a mentor.
