How Long Does It Take to Become a Home Inspector?

Quick Answer

Becoming a licensed home inspector takes 2–6 months depending on your state's requirements and whether you study full-time or part-time. The process includes pre-licensing coursework (60–180 hours), passing a national or state exam, and completing supervised inspections.

Timeline Breakdown by Phase

Phase	Duration	Details
Pre-licensing education	2–12 weeks	60–180 classroom or online hours
Exam preparation	1–2 weeks	Practice tests and review
National/state exam	1 day	NHIE or state-specific exam
Field training	2–8 weeks	Supervised ride-along inspections
License application	1–3 weeks	Background check and paperwork

State-by-State Requirements

Pre-licensing education hours vary significantly by state. Here are some examples:

State	Required Hours	Supervised Inspections
Texas	194 hours	None required
California	120 hours	None required
Florida	120 hours	120 inspections
New York	140 hours	100 inspections
Illinois	60 hours	250 inspections
Ohio	80 hours	None required

Some states like Colorado and South Dakota have no licensing requirements at all, meaning you could technically start working immediately after self-study.

Steps to Become a Home Inspector

1. Research your state's requirements — Check with your state's licensing board for specific education hours and exam rules.
2. Complete pre-licensing coursework — Enroll in an accredited program (online or in-person). Programs like AHIT, ICA, and InterNACHI are widely recognized.
3. Pass the exam — Most states accept the National Home Inspector Examination (NHIE), a 200-question multiple-choice test.
4. Complete field training — Some states require supervised inspections before or after licensing.
5. Apply for your license — Submit your application, proof of education, exam scores, and any required insurance documentation.
6. Purchase equipment and insurance — Obtain E&O insurance and inspection tools (moisture meter, electrical tester, infrared camera).

Factors That Affect the Timeline

• Full-time vs. part-time study: Full-time students can finish coursework in 2–4 weeks; part-time students may need 8–12 weeks.
• State requirements: States with high hour requirements and mandatory field inspections take longest.
• Online vs. in-person: Online courses offer more scheduling flexibility and can accelerate completion.
• Prior experience: Construction or engineering backgrounds can make coursework faster to absorb.

Cost Estimate

Expense	Typical Cost
Pre-licensing course	$500–$1,500
NHIE exam fee	$225
State license fee	$100–$400
E&O insurance (annual)	$1,200–$2,500
Tools and equipment	$500–$2,000
Total startup cost	$2,525–$6,625

What to Expect on the NHIE

The National Home Inspector Examination covers structural systems, electrical, plumbing, HVAC, roofing, insulation, and interior/exterior components. You need a scaled score of 500 out of 700 to pass. The national pass rate is approximately 50–60%, so thorough preparation is essential.
