How to Become a Home Inspector

What is a home inspector?

A home inspector performs building inspections on homes, townhomes, condos, and other residential properties before they are sold to assess the value and condition, ensuring that they are up to code and safe to inhabit. They may inspect homes for a seller or buyer, or they may perform inspections of new construction to ensure they meet local ordinances and codes. 

Home inspectors carefully inspect the structure of a home, including the foundation, walls, windows, doors, and roof. They also look at major systems in the home, such as the air conditioning unit, electrical wiring, plumbing system, and security system. They also check any major appliances in the home and all fixtures to make sure they are working properly and free of leaks or clogs. They look for any issues or potential issues and write up inspection reports outlining any repairs that need to be done. They generally take photos to include in the report and provide reports to their clients.  

An inspection by a home inspector may include uncovering cracks in the foundation, roof leaks, insufficient insulation, cracks or holes in walls, or doors that don’t close properly. They might find faulty wiring in the electrical system or exposed wires, leaks or bad pipes in the plumbing system, or drainage problems with the heating/cooling system. They check the codes and permits and report systems that aren’t up to date. They also might find signs of termite damage, mold, asbestos, lead paint, radon gas, or other hazardous materials. An inspection of the yard might uncover poor drainage, broken sprinkler systems, or improper landscaping. They typically meet with the client after the inspection, show them the report, offer explanations as needed, address any questions or concerns, and give recommendations for repairs or other actions to remedy issues found during the inspection.

Qualifications and eligibility

To be eligible to work as a home inspector, you will need to have a high school diploma or equivalent. Some employers prefer candidates who have a bachelor’s degree in construction, building science, engineering, or a related field. Typically, home inspectors receive on-the-job training.

Many states require home inspectors to be licensed or certified.  They typically have to complete training courses on how to inspect a home, how to report findings, safety precautions, and more. To earn a license or certification, you are required to pass an exam administered by the American Society of Home Inspectors or the National Association of Home Inspectors. The requirements vary by state and can include a combination of education and experience. Check the license or certification requirements in the state where you live. Most states also require liability insurance if it isn’t offered by your employer. 

Home inspectors must have excellent technical knowledge as well as an in-depth understanding of building materials, methods, tools, construction principles, and home repair. They need to read and interpret building plans, construction documents, and other technical documents. Communication and customer service skills are a necessity as they write up reports, verbally relay findings to their clients, explain potential risks, and address client questions or concerns concerning technical issues in a way that the client can understand. Good listening skills and empathy are also needed. 

Home inspectors need excellent problem-solving skills as they may encounter a variety of different problems from day to day and need to find and report on solutions to problems they find. Exceptional organizational skills are essential as well to keep track of many different types of information. 

A current driver’s license is required as home inspectors travel to locations they inspect. Home inspectors must have a good understanding of basic home systems, including plumbing, HVAC units, electrical, and security alarms. They should be comfortable climbing into dark, tight, and/or confined areas such as attics and crawl spaces. They also must be able to climb onto roofs and walk around without fear of heights. Another essential qualification needed for a home inspector is attention to detail as they must closely inspect home systems for flaws or problems.

Home inspectors need a strong understanding of building codes, local ordinances, and government regulations as they apply to home construction.

Work environment

Home inspectors work in a wide range of settings, which can include office buildings, homes, apartment complexes, or other buildings. They travel to different locations every day and may travel extensively to cover a wide area. They can be exposed to a variety of traffic and weather conditions. They may have to climb into cramped or uncomfortable spaces, on roofs, or damp crawl spaces on any given day. The work can be physically challenging and stressful at times. Some home inspectors are self-employed, while others work for home inspection companies.

Typical work hours

Home inspectors typically work a standard 40-hour week. However, they may have to work evenings and/or weekends to accommodate client schedules or needs. Some home inspectors may do on-call work where they respond to emergencies at any time. 

Types of home inspectors

Home inspectors typically conduct general inspections that cover structural components, exterior components, the roof, plumbing, heating and air conditioning, major appliances, ventilation, insulation, and windows and doors. But there are times when a specialized type of home inspection is needed. Some common types of special home inspections include:

  • Radon testing – radon is an odorless, colorless gas that gets released from well water, building materials, and soil, and can enter your home through cracks. The Environmental Protection Agency (EPA) estimates that radon exposure is the second-leading cause of lung cancer in the U.S. and is found in elevated levels in about 1 in 15 homes. Home inspectors perform Radon testing to determine if a home is at risk of high radon levels. 
  • Plumbing and water systems inspection – a plumbing inspection goes deeper than a general inspection to detect issues with connections under the sinks, shutoff values, fixtures, and appliances. Inspectors check that the installation is up to code, check the water pressure, and the water heater, and verify everything is draining properly.
  • Termite inspection – termites can cause serious damage to a home. A termite inspection can ensure that your home is safe from infestation. Inspections cover not only termites, but also wood-boring beetles, carpenter ants, and other wood-destroying organisms. Many states require a termite inspection to close on a home. 
  • Mold inspection – typically, if you see mold, you need to remedy the situation immediately. Mold inspections are recommended if a homeowner or potential homeowner is concerned the mold might be present. 
  • Foundation inspection – inspectors check the foundation during a routine inspection. If they find potential issues such as drainage problems, nearby tree roots, cracks, or indications of foundation movement, they generally recommend having a foundation inspection completed by a residential structural engineer.
  • Chimney inspection – this type of inspection verifies that the chimney and fireplace are venting properly and may uncover cracks or other issues with the chimney. Chimney inspectors also find unwanted guests such as birds or bats nesting in chimneys that haven’t been used in a while. 
  • Heating, ventilation, and air conditioning (HVAC) inspection – an HVAC inspection determines how well the system is working and what kind of shape it’s in. Inspections cover thermostat calibration, heat pumps, electrical connections, air filters, safety controls, quality of installation, and many other checks.  
  • Roof inspection – roof inspections detect signs of leaks, damage, mold, or rotting wood underneath the shingles. They can also find areas of poor insulation where heat is escaping. Roof inspections are recommended if the roof is 20 to 25 years old or shows visible signs of loose shingles, cracks, etc. 
  • Electrical inspection – an electrical inspection goes beyond a general inspection to check for ungrounded outlets, exposed wiring, spliced wires, improperly modified electrical panels, and other electrical issues that could pose a risk to homeowners.
  • Lead-based paint inspection – The use of lead-based paint has been banned since 1978. Inspections are highly recommended for older homes as inhaling lead fumes can cause serious health issues, especially for children. 
  • Sewer or septic system inspection – septic system inspections check how close the tank is to drainage areas, wells, and streams, verify when the tank was last pumped, check the sludge level, and determine whether the tank is the right size for the house. 
  • Asbestos inspection – Many homes built before 1980 used asbestos in the construction process. An inspection of an older home can determine whether asbestos is present or not.

The earning potential for a home inspector can vary greatly depending on geographic location, education, and experience.

1. Get a high school diploma

You will need a high school diploma or a GED to work as a home inspector. Some employers prefer some college courses or a college degree in construction, engineering, or a related field.

2. Check the licensing requirements in your state

Because the requirements vary from state to state, it is important to find out what the requirements are in your state. Most states do require a license or a certification, which entails a certain number of coursework hours and passing an exam. The coursework, number of hours needed, and the exam can vary by state. Many states also require a certain number of on-the-job training hours under the supervision of an experienced inspector.

Check out the licensing and experience requirements and get application documents for your state.

3. Get training

Even if your state doesn’t require home inspectors to be licensed, you should still take courses to learn more about home inspection. This can help give you an edge over your competition and better prepare you for your career. If your state does require a license, make sure you complete the necessary coursework in the time frame allotted, which can vary by state. Many home inspector training schools offer online, in-class, and flexible training options. Some top training schools include:

  • American Home Inspectors Training (AHIT): Before paying, you can attend a free live webinar. Then, you can choose between online courses or in-person courses across the country. This training will teach you everything you need to know about inspecting homes.

4. Pass the state licensing exam

If you live in a state that requires home inspectors to have a license, you will have to pass an exam before becoming a home inspector. The majority of states require that you pass the National Home Inspection Exam, but some states off these options as well:

5. Choose your career path

After you’ve passed the licensing exam (if needed), or have met the requirements in your state, you can either apply for work with an established firm, start your own business, or buy a home inspection franchise. Each path has its advantages and disadvantages and choosing the one that’s right for you will depend on your career goals and ambitions. 

6. Get liability insurance

If you own a home inspection business, work for yourself, or your employer does not provide insurance for you, you will need to purchase errors and omissions (E&O) and general liability (GL) insurance. The costs and specific requirements of obtaining insurance can vary by state. E&O insurance protects you and your company if a client or homeowner accuses you of failing to report findings. GL insurance protects you from claims of missing or damaged items from the property.

You can get E&O and GL insurance through companies like Next Insurance, or from the International Association of Certified Home Inspectors (InterNACHI). Also, you can check what specific plans might be available in your state.
