Building Inspector

What building inspectors make

The national median is $74,690 a year. The bottom tenth earn $47,140 or less and the top tenth $114,200 or more, in 2025 figures. These are the federal wage survey figures for Construction and Building Inspectors, which covers building, electrical, plumbing and public works inspectors together. Pay also varies by state and city: O*NET OnLine (the Department of Labor's occupation database) has a local wage tool that shows the figures for your area.

The lower end

First-year inspectors at small cities and private inspection firms usually start in this part of the range. Few people start at 18. Many inspectors spend years in a construction trade first and come in with that experience already paid for.

Where pay is highest

California ($101,290) and Connecticut ($98,670) come next. Mississippi is the lowest, at $50,250. A building official who runs a whole city department is the top of the ladder.

What it costs to get there

File the FAFSA (Free Application for Federal Student Aid) before you enroll anywhere. A Pell Grant can cover most of a community college bill, and this is a short, cheap program to begin with.

Benefits

• A real pension

  Many inspectors work for a city, county or state, which still means a defined-benefit retirement plan.

• Health insurance from day one

• Public Service Loan Forgiveness

  Government employment counts toward this federal program, which can wipe out remaining student loans after 10 years of payments.

• A take-home vehicle

  Many agencies give inspectors a truck and a fuel card.

• Daytime hours

  Inspections happen when crews are working, so nights and weekends are rare.

The path to becoming a building inspector, step by step

Two routes in: years on the tools, or a short college program. Both end at the same certification exams.

1. 1

   High school diploma or GED (General Educational Development) test

   Grade 12

   Take every shop, drafting and math class your school offers.

2. 2

   Get construction experience

   3 to 5 years

   Work as a carpenter, electrician, plumber or concrete finisher. Employers want somebody who has actually built what they are inspecting.

3. 3

   Or take a building inspection program

   1 to 2 years

   A 2-year associate degree or a shorter certificate at a community college. Some programs run fully online.

4. 4

   Pass certification exams

   Weeks of study each

   Computer-based code exams run by the International Code Council. Residential building inspector is the usual first one.

5. 5

   Get hired and add certifications

   Ongoing

   Start as a residential inspector, then add commercial, mechanical, electrical and plans examiner tickets to become a combination inspector.

High school courses that help you become a building inspector

• Math

  Spans, loads, grades and setbacks are all arithmetic and geometry.

• Construction technology or shop

  You cannot inspect framing you have never built.

• Drafting or computer-aided design

  Half the job is reading plans.

• English

  Inspection reports have to hold up when somebody argues with them.

Time and money, at a glance

Who licenses this job

There is no national license. About 22 states make building inspectors hold a state license, registration or certification, among them Florida, New York, Pennsylvania, Michigan, Tennessee, Louisiana and New Mexico. Several give new hires a year or two to earn it. In the rest, Minnesota for example, the city or county that hires you sets the rules, which in practice means certification from the International Code Council. Check your state before you spend money on anything.

Where people study

• Portland Community College, Oregon

  A 2-year associate degree in Building Inspection Technology plus a shorter residential plans examination certificate. Required classes are offered online.

• Community colleges in most states

  Look for programs named building inspection technology, construction management or code administration.

• Code council training

  The International Code Council sells the courses and study guides that most inspectors actually use to pass exams.

• No program at all

  Plenty of inspectors never take a class. They work a trade, study the code book, and sit the exam.

Certifications that open doors

Each one is a separate exam. Inspectors collect them.

• Residential and commercial building inspector

  The two core tickets.

• Plans examiner

  Desk work reviewing drawings before anything is built.

• Mechanical, electrical and plumbing inspector

  Hold all of them and you are a combination inspector, which small towns need badly.

• Certified building official

  The credential for running a department.

• Accessibility and energy code

  Growing areas as states tighten energy rules.

Nice-to-haves

• A clean driver's license

  You will drive between many sites a day.

• Spanish

  On a lot of job sites it is the language of the crew.

• Calm under pressure

  You are telling people their expensive work has to be torn out.

• Computer skills

  Permit software, tablets and photo documentation are the daily tools.

The private side

Not every inspector works for a government. Private third-party inspection firms are hired by cities that cannot staff their own departments, and by builders who need special inspections on concrete, welding or soils. The hours can be longer, with no pension. A related side path is home inspection, where you work for the buyer of a house rather than for the code.

What a building inspector does day to day

You get your route at 7am: maybe 10 inspections spread across town. A footing inspection before concrete goes in, a framing inspection where you check every strap and nail pattern, a final before a family can move in. Each stop is 15 to 45 minutes of measuring, photographing and writing. Between stops you are in the truck typing notes into permit software. Afternoons often end back at the office answering calls from builders who disagree with you.

The honest pros and cons of being a building inspector

Work life

Similar paths

• Home InspectorCrawl through a house before someone buys it, then write down everything wrong with it.
• Code Enforcement OfficerKnock on doors about unsafe buildings, illegal work, junk lots and zoning. The city's rules only exist if somebody enforces them.
• General ContractorYou do not swing every hammer. You price the job, hire the trades, hold the schedule, and carry the risk.

The code is a book, and it keeps changing

Most states build from the International Building Code and International Residential Code, written by the International Code Council and updated every three years. States and cities then add their own amendments, so the rules in Texas are not quite the rules in California.

An inspector can stop an entire job

A failed inspection means the work gets corrected before anything else goes on top of it. No certificate of occupancy means nobody legally moves in, no matter how finished the building looks.

This job is not growing

O*NET OnLine (the Department of Labor's occupation database) projects little or no change in employment for construction and building inspectors from 2025 to 2035. It counted about 153,900 inspectors in 2025, with about 14,800 openings a year.

After a disaster, inspectors go in first

Once a hurricane, tornado or earthquake passes, trained inspectors tag buildings green, yellow or red so people know what is safe to enter. Many travel to other states to help.
