What should a plumbing inspector job description include? (free template)

Duties and responsibilities.

Write the description before you advertise the job.

Under the Americans with Disabilities Act, essential functions are the fundamental duties of the position, not the marginal ones, and a written description prepared before advertising or interviewing is evidence of what is essential — a function can be essential because the job exists to perform it, because few employees are available to share it, or because it is highly specialised.

If you need the day-to-day definition of the role first, our guide to what a plumbing inspector does covers the job; this page stays on the employer's side of it.

The seat exists under more than one roof, and the posting should say which one it is.

Among construction and building inspectors — the occupation BLS counts plumbing inspectors in — local government (excluding schools and hospitals, in BLS's industry breakout) employs the most (53,640 jobs in May 2025), followed by architectural, engineering, and related services (47,310).

An inspector reading your posting is trying to work out which of those settings yours is, so say which one it is.

Split the work the way your inspection calendar actually runs.

Residential or commercial.

Rough-in and underground, final only, or the full sequence.

New construction, remodels, or both.

Field inspections, plans review, or both.

Backflow and cross-connection work, or not.

Then list the duties that make the job what it is at your shop: conducting [rough-in / underground / final] plumbing inspections on [residential / commercial] projects, checking installations against [the code name and edition your jurisdiction enforces], documenting findings and writing correction notices, scheduling and completing re-inspections, keeping inspection records current in your inspection software, coordinating with contractors, builders and permit staff, and explaining code findings plainly to the people who have to fix them.

Physical demands, stated plainly.

Inspecting is physical: crawlspaces, attics, ladders, trenches, active job sites.

Before a conditional offer you may state the job's physical requirements and ask whether the applicant can meet them.

Putting them in the description does double duty: it tells candidates what the day costs their body, and it gives you compliant wording to screen on later.

Certification and licence requirements — worded exactly.

Never write a generic "must be a licensed plumber" or "certification required" line: licence and certification names differ by jurisdiction, and a requirement that fits nowhere reads to a working inspector as an employer who has not checked their own rules.

Our research did not confirm a standard set of plumbing-inspector hiring requirements — what applies varies by jurisdiction — so ask the city or county building-safety department that covers your work, or your state licensing board, what an inspector there must hold, and put that exact name in the posting.

Where industry certifications apply, name them exactly as the issuing body does, and match the certification to the seat.

ICC's P1 is the Residential Plumbing Inspector certification; its P2 Commercial Plumbing Inspector credential covers commercially installed plumbing systems, storm water, special waste, and non-flammable medical and non-medical oxygen piping under the International Plumbing Code.

The same ICC family numbers P3 Plumbing Plans Examiner and FG Fuel Gas Inspector, offered on 2021 and 2024 code editions — so a plans-review seat is a P3 line and a fuel-gas seat is an FG line, not "plumbing certification".

If you list a preference for one, a working inspector will check the format: P1 is 60 multiple-choice questions over 2 hours, open book; P2 is 50 questions over 2 hours, open book.

Outlines age, so confirm the current format in ICC's exam catalog before you screen on it.

ASSE's professional-qualification standards run parallel: Series 16000 covers 16010 Plumbing Inspector and 16040 Plumbing Plan Examiner, and if the seat covers cross-connection control, ASSE 5110 Backflow Prevention Assembly Tester is the tester credential in its Series 5000.

ASSE certifications renew every three years, so if the seat needs a current credential, write "current" and say whether you fund the renewal.

If the hire may qualify after you hire them, say so: "[Certification or licence, named exactly] (or ability to obtain within [N] days)" is an honest line, and asking about required certifications and licences before an offer is allowed.

Verify before you post.

Inspector hiring rules are jurisdiction-specific and they change; the certifications named above are the ones our research confirmed, not a complete map.

Confirm the current requirements with the authority over your inspections — the state licensing board, or the city or county building-safety department — and treat this page as employer information, not legal advice.

The confirmed certifications, with their exam formats, are in our guide to how to hire a plumbing inspector.

Pay and pay-plan disclosure.

Post a real range — the low, the high, and how the plan works.

A number of states now require the range in the posting itself.

As of September 2026, laws confirmed to require a pay range in job postings include California (employers with 15 or more employees), Colorado, Washington State (15 or more), the District of Columbia, Maryland (work performed at least partly in the state), Maine (10 or more, from July 29, 2026), Massachusetts (25 or more employees in the state), Minnesota (30 or more employees in Minnesota), Illinois (15 or more), New Jersey (10 or more employees over 20 calendar weeks), New York (4 or more, for jobs performed at least partly in New York), Vermont (5 or more) and Virginia (from July 1, 2026).

Delaware's law is signed but does not take effect until September 2027.

Connecticut and Rhode Island do not require the range in the posting but require the wage range to an applicant — Connecticut on request or by the time of an offer, Rhode Island on request and before pay is discussed.

Our research did not confirm posting requirements in Hawaii or Nevada, and city ordinances were outside this check, so verify each state — and each city — where the job is located; our guide to pay transparency laws by state keeps the state detail in one place.

Several of these laws reach past the number.

Colorado requires a benefits description and how and when to apply in every posting; Illinois lets a hyperlink to a public page carrying the pay scale and benefits satisfy the rule; Minnesota and Washington require a general description of benefits; Washington, D.C. requires the minimum and maximum projected pay in every listing and disclosure of healthcare benefits before the first interview.

If any part of the seat is paid on commission or incentive, say so in the posting.

New York's labor department requires it — postings must clearly state if a position is commission-based — and Vermont goes the other way: an ad for a job paid on commission, in whole or in part, need only disclose that fact and may skip the range.

Name the pay basis — hourly, salaried, or a published grade or step scale if the seat has one — and say how overtime, weekend or after-hours inspection time is paid rather than leaving the new hire to find out.

One calibration note before you pick the numbers: BLS publishes no "plumbing inspector" wage series — inspectors sit inside SOC 47-4011, Construction and Building Inspectors.

In May 2025 that occupation's national median was $35.91/hour ($74,690/year), with the middle 50% earning $58,860–$94,710.

Anchor the range to your own jurisdiction, budget and pay scale rather than a national headline; our plumbing inspector salary page carries the federal benchmark figures, nationally and by state.

Schedule, on-call, truck and tools.

These lines filter more inspectors than any perk, so state each one instead of letting the new hire discover it.

Schedule: give the working days and hours, whether inspections run as booked routes or per-permit, and the honest seasonal shape of the construction calendar where you inspect.

After-hours: if the seat carries weekend, holiday or emergency inspections, say when and how they are paid; if it does not, saying so costs you nothing and reassures everyone reading.

Territory and travel: name the jurisdiction, routes or service area the inspector covers and how much windshield time is in the week, and say whether a vehicle is provided or mileage is paid.

Tools and equipment: say what you supply — current code books, test gauges and equipment, mirrors and flashlights, tablet and inspection software, PPE — and what the inspector is expected to bring.

If you fund certification renewals or continuing education, name it; a posting that pays the three-year ASSE renewal cycle reads differently from one that does not.

Good inspectors read postings the way managers wish candidates read resumes: fast, and looking for reasons to stop.

The fastest reasons to stop are all fixable in the copy.

No pay range.

Inspectors moving between employers — public or private — shop jobs on pay, and a posting that hides the number reads as a number worth hiding.

In the states listed above it is also a legal exposure, not just a conversion problem.

A certification line that names nothing.

"Certified inspector required" tells a working inspector nothing about the seat: not residential or commercial, not field or plans review, not which code edition.

Our research did not confirm a standard set of requirements to fall back on either.

Name the certification exactly, match it to the seat, or state plainly that you will help the right candidate obtain it.

Age-coded wording.

Terms like "young", "recent college graduate", "boy" or "girl" violate age-discrimination rules unless a statutory exception applies, and help-wanted ads may not show a preference for, or discourage, applicants based on race, color, religion, sex, national origin, age 40 or older, disability or genetic information.

Describe the work, not the person you imagine doing it.

Questions the posting cannot ask.

Stating the physical demands and asking whether the applicant can meet them is allowed before a conditional offer.

Disability-related questions and medical exams before a conditional offer are not — keep them out of the posting, the application form and the phone screen.

Referral-only hiring.

Recruiting mainly by word of mouth through a mostly one-group workforce can itself be discriminatory if almost all hires come from that group.

Post the job publicly.

Small-shop assumptions.

Federal EEO laws cover private employers with 15 or more employees, the age law covers those with 20 or more, and the Equal Pay Act covers virtually all employers — but state laws often cover smaller employers, so check yours.

Federal contractors must include the equal-consideration tagline in job ads; many other employers add an equal-opportunity line voluntarily.

Screening rules you have not checked.

Background-check, ban-the-box and paid-sick-leave rules were not verified state by state in our research — confirm the rules where you hire before you screen.

Eligibility verification, before the first day.

While applications come in, check whether your state mandates E-Verify.

Florida requires private employers with 25 or more employees to use E-Verify for new hires, and North Carolina requires employers with 25 or more employees in the state to do the same.

South Carolina requires every private employer to verify every new employee within three business days, and Arizona, Alabama and Mississippi require every employer to use it too.

The thresholds reported for Georgia, Tennessee and Utah were not verified in our research, so check your state's current rule directly.

Federal contractors covered by the FAR E-Verify clause must enroll within 30 calendar days of contract award.

With the copy fixed, put the posting where inspectors actually look: browse current plumbing inspector jobs to see what candidates see on the board, and our guide to how to write a job ad for HVAC technicians walks the ad copy itself — the ad-wording rules above apply to any job ad, an inspector posting included.

When you are ready to run the full process, the guide to how to hire a plumbing inspector covers sourcing, pay, screening and the first 90 days.

This page is employer career information, not legal advice. Confirm inspector hiring requirements with the authority over your inspections — the state licensing board, or the city or county building-safety department — pay-posting rules with each state labor department, and employment-law questions with an employment attorney.
