Home Inspector Schools & Programs

Construction and building inspectors earn a median salary of $67,700 per year (BLS, OEWS, May 2024), with the top 10% earning over $101,550. Home inspector programs train students to examine residential properties systematically – evaluating structural, electrical, plumbing, HVAC, and roofing systems so buyers and sellers can make informed decisions. With approximately 14,800 openings projected annually and a training timeline of just 3 to 6 months, home inspection offers a flexible, in-demand career path.

What Is a Home Inspector Program?

Home inspector programs teach students to perform thorough, standards-based inspections of residential properties. Students learn to evaluate all major home systems – foundation and structure, roofing, electrical, plumbing, HVAC, insulation, and interior/exterior finishes – and to document their findings in professional inspection reports. Programs follow the Standards of Practice established by organizations like ASHI (American Society of Home Inspectors) or InterNACHI (International Association of Certified Home Inspectors). With approximately 130,800 construction and building inspectors employed nationwide, the field offers steady demand driven by real estate transactions, new construction, and building code compliance.

What You’ll Learn

• Structural systems: foundations, framing, floors, walls, and ceilings
• Roofing: shingles, flashing, gutters, drainage, and signs of water intrusion
• Electrical systems: service panels, wiring types, outlets, grounding, and common deficiencies
• Plumbing systems: supply lines, drain/waste/vent systems, water heaters, and fixtures
• HVAC systems: furnaces, air conditioners, heat pumps, ductwork, and thermostats
• Insulation, ventilation, and moisture management
• Report writing: documenting findings with photos, descriptions, and recommendations
• Business practices: marketing, client relations, liability, and insurance
• Exterior evaluation: siding, grading, drainage, driveways, and walkways
• Safety hazards: radon, asbestos, lead paint, carbon monoxide, and mold indicators

How Long Does Training Take?

State-required training hours for home inspectors range from 60 to 200+ classroom hours depending on the state, with most programs costing between $1,500 and $8,000. Most programs can be completed in 2 to 4 months of full-time study or 4 to 6 months part-time. Some states also require supervised field inspections (typically 10 to 25 inspections) before you can work independently, which adds time to the process. InterNACHI’s online training program can be completed at your own pace and is accepted in many states. Total time from enrollment to licensure is typically 3 to 6 months. Students should also budget $500 to $1,500 for inspection tools such as moisture meters, electrical testers, thermal cameras, flashlights, and ladders.

Admissions & Requirements

• High school diploma or GED required in most states
• Must be at least 18 years old
• No prior construction or trade experience required, though it is helpful
• Physical ability to climb ladders, access crawl spaces, attics, and roofs
• Valid driver’s license and reliable transportation to reach inspection sites
• Some states require a background check for licensing
• Students should budget for inspection tools – typically $500 to $1,500
• Comfort with technology for digital report writing and photo documentation

Licensing & Certification

Most states require a home inspector license, though requirements vary significantly. Common requirements include completing an approved training program, passing a state or national exam, and carrying errors and omissions (E&O) insurance. The National Home Inspector Examination (NHIE) is the most widely recognized exam, accepted in over 30 states. ASHI offers the Certified Inspector (ACI) designation, while InterNACHI offers the Certified Professional Inspector (CPI) credential. Several states also require continuing education (16 to 40 hours per renewal cycle). States like Texas and Illinois have particularly detailed licensing requirements, including higher training hour minimums and specific exam protocols.

Career Outlook & Salary

The BLS reports a median annual wage of $67,700 for construction and building inspectors, with the top 10% earning over $101,550 (BLS, OEWS, May 2024). Employment is projected to grow 3% from 2022 to 2032, generating approximately 14,800 openings per year. The mean annual wage is $74,470, reflecting higher earnings for inspectors in metropolitan areas and those with specialty certifications. Home inspectors who add ancillary services – radon testing, mold assessment, thermal imaging, wind mitigation, and 4-point insurance inspections – can significantly increase their per-inspection revenue. Self-employed inspectors who build strong referral networks with real estate agents often earn well above the median, with income directly tied to how many inspections they perform.

Where You’ll Work

Most home inspectors are self-employed, running their own inspection businesses and scheduling appointments directly with clients or through real estate agent referrals. Some work for home inspection companies that provide leads, scheduling, and administrative support. Government agencies at the municipal, county, and state level employ building inspectors for code enforcement and permitting. Insurance companies hire inspectors for property condition assessments. New construction builders and real estate investment firms also use inspectors. The work is primarily in the field – inspecting homes, crawl spaces, attics, and roofs – with office time devoted to report writing and business management.

Online vs In-Person Options

Home inspector training is well-suited to online and hybrid delivery. The classroom theory – building systems, inspection procedures, report writing, and state regulations – can be taught effectively through online courses, video demonstrations, and virtual inspections. InterNACHI’s online program is one of the most popular training paths in the industry. However, supervised field inspections (required in many states) must be completed in person alongside a licensed inspector. Some programs offer in-person field training days to supplement online coursework. Look for programs that include hands-on inspection practice, as field experience is essential for building confidence before working independently.

Career Guide

Home inspection offers a career path with significant independence and earning potential. Many inspectors start by performing standard pre-purchase home inspections and gradually expand into specialty services like radon testing, mold assessment, thermal imaging, and commercial property inspections. Building strong relationships with local real estate agents is one of the most effective ways to establish a steady pipeline of inspection work. Some inspectors advance into training and education roles, becoming instructors for home inspection schools or mentors for new inspectors in their area. Others transition into related fields like building code enforcement, construction management, or real estate appraisal.

FAQs

How much do home inspectors earn?

Home inspector income varies based on location, experience, and how many inspections you perform per week. Many home inspectors are self-employed and set their own fees, which typically range from $300 to $500 per inspection. Full-time inspectors who complete 4 to 6 inspections per week can earn a solid income, with top earners adding revenue through specialty services like radon testing, mold assessment, and thermal imaging.

Can I be a home inspector with no construction background?

Yes. Home inspector training programs are designed to teach building systems from the ground up. You do not need prior construction, electrical, or plumbing experience. However, people with trades backgrounds (electricians, plumbers, HVAC technicians, general contractors) often transition into home inspection successfully because they already understand building systems. The training focuses on identifying deficiencies and safety concerns, not performing repairs.

How long does it take to start earning money as a home inspector?

From enrollment to first paid inspection, the timeline is typically 3 to 6 months depending on your state’s requirements. States with lower hour requirements and no mandatory supervised inspections allow a faster start. Building a client base takes time – most new inspectors market to real estate agents, build an online presence, and join referral networks. Many inspectors reach a steady workload within 6 to 12 months of launching their business.

What tools and equipment do home inspectors need?

A basic home inspection toolkit includes a moisture meter, electrical circuit tester, GFCI tester, carbon monoxide detector, infrared thermometer or thermal imaging camera, a quality flashlight, extension ladder, and safety equipment. Digital tools include a tablet or laptop for report writing software, a digital camera, and a measuring device. Startup equipment costs typically range from $500 to $1,500 for basic tools, with thermal imaging cameras adding $300 to $1,000 or more. Many inspectors invest in additional specialty tools as they expand their services.

Do I need errors and omissions insurance?

Most states require home inspectors to carry errors and omissions (E&O) insurance, and it is strongly recommended even in states where it is not mandatory. E&O insurance protects you against claims arising from missed deficiencies or report errors. Annual premiums typically range from $1,000 to $3,000 depending on coverage limits, claim history, and state requirements. General liability insurance is also recommended to cover on-site accidents.

What specialty certifications can increase my income?

Radon testing and mitigation certifications, mold assessment credentials, and thermal imaging (infrared thermography) certifications are among the most common and profitable add-ons. In coastal and hurricane-prone states, wind mitigation and 4-point insurance inspection certifications are in high demand. Each specialty service allows you to charge additional fees per inspection, and many clients request bundled services. Earning these certifications typically requires short training courses and an exam.
