How to Become a Home Inspector: Licensing, Training & Salary
Home inspection is one of the few professional careers that offers a flexible schedule, no college degree requirement, and $65,000+ earning potential — with the ability to be your own boss.
Why People Become Home Inspectors
Home inspection attracts career changers from trades backgrounds (electricians, plumbers, contractors), real estate professionals looking to pivot, and people who want to run their own business without the overhead of a large operation. The appeal is consistent:
A trade background or construction knowledge is often more valuable than a four-year degree.
Most inspectors set their own hours and control their own booking calendar.
Total investment to start is $1,500–$5,000, compared to $50,000+ for most small businesses.
Experienced inspectors routinely earn $85,000–$100,000+ per year.
Most home inspectors are self-employed or run small businesses with 1–3 employees.
Each property presents a unique combination of systems, ages, and conditions.
Steps to Become a Home Inspector
Most states require 60–200 hours of approved coursework covering structural systems, roofing, electrical, plumbing, HVAC, and report writing. Programs from AHIT, ICA, and InterNACHI Online are widely accepted. Courses are available online, in-person, and hybrid.
32 states require passing a licensing exam. The National Home Inspector Examination (NHIE) is accepted in most states. Some states have their own exams. The NHIE costs $225 and covers 200 questions across four domains.
Several states require completing a set number of inspections under a licensed inspector before you can work independently. Texas requires 25 supervised inspections. New York requires 40. Check your state's specific requirements.
E&O insurance protects you if a client claims you missed a defect. Most states require it; even those that don't require it strongly recommend it. Annual premiums typically run $1,500–$3,000 depending on coverage limits.
InterNACHI and ASHI certifications go beyond state minimum requirements and signal to clients that you operate at a higher professional standard. Many real estate agents specifically recommend certified inspectors.
Register your business entity (LLC is standard), open a business bank account, obtain a business license if required locally, invest in inspection software (HomeGauge, Spectora, or similar), and begin marketing to real estate agents.
