Water heater repair Las Vegas: who may do it
Water heater repair Las Vegas homeowners pay for is licensed work in Nevada, even when the job is small. Renters usually shouldn't pay at all. Here is how to stop the damage, check who you're hiring, what the contract must say, and what your landlord owes you. This page doesn't list plumbers. It tells you what the law requires of whichever one you call.
What to do first
Who is allowed to do the work
Nevada defines a contractor as anyone who repairs or alters a building or structure, or offers to (NRS 624.020(2)). Acting as one without an active license is unlawful unless an exemption applies (NRS 624.700(1)).
The well-known exemption is for repair work under $1,000. It does not cover work of a type done by a plumbing, electrical, refrigeration, heating or air-conditioning contractor. It also doesn't cover work that needs a building permit (NRS 624.031(6)). So "it's only a small job" is not a way around the license for a water heater.
The license class that names this work is C-1 plumbing and heating. Subclass C-1h, water heaters, covers "the installation, replacement and repair of water heaters," including the connection to existing water and gas lines and the venting. Subclass C-1d, plumbing, also covers "systems to heat potable water" and a permanent means to supply gas (NAC 624.190). If you own and live in the home, the owner's exemption runs through the Contractors Board, so ask them before doing it yourself (NRS 624.031(5)). A store that only sells you the unit doesn't need a contractor's license (NRS 624.020(3)). Installing it is another matter. The exemption for installing a finished product reaches only items that don't become a permanent fixed part of the structure (NRS 624.031(7)).
What to check, and why it matters
| Check | Why | Source |
|---|---|---|
| License is active | A contract with someone who needed a license and had none is void from the start | NRS 624.700(1), (4) |
| Name on the license matches who you're paying | A license can only be used in the licensee's name, or by its employee | NRS 624.3014 |
| Monetary limit covers the job | Every license carries a limit, and going over it is cause for discipline | NRS 624.220(2), 624.3015(2) |
| Mobile or manufactured home | The contractor generally needs a license under NRS 489.311 to repair one | NRS 624.3015(5) |
| Permit | On a single-family home covered by the contract rules below, the contractor must get all necessary permits | NRS 624.970(6) |
Read 2026-11-01 off the Nevada Revised Statutes: chapters 108, 118A, 455C and 624 revision stamped 4/15/2026; Nevada Administrative Code chapter 624, revised 6/7/2026. Local permit rules aren't in these chapters. Ask the contractor, or your city or county building department, whether your job needs one.
What the contract must say if you own and live in the home
These rules apply to a licensed contractor working for the owner-occupant of a single-family home, and they cover repairs (NRS 624.970(1), (7)). The contract must be in writing and show:
| Item | The rule | Source |
|---|---|---|
| Who | Contractor's name, address, license number and monetary limit | NRS 624.970(2)(a) |
| What and when | A description of the work and the estimated finish date | NRS 624.970(2)(d), (e) |
| Price | The total, including taxes | NRS 624.970(2)(f) |
| Deposit | No more than $1,000 or 10% of the price, whichever is less, unless the contractor has the $100,000 consumer bond or Board relief. A contract that breaks this can be voided by you | NRS 624.970(1)(b), (2)(g) |
| Added costs | A change in work or price must be in a written change order you accept, or it can't be enforced against you | NRS 624.970(2)(i) |
| Paying as you go | Payments can't run ahead of the value of work done, apart from the deposit, unless a bond is included | NRS 624.970(2)(k) |
| Your copies | A legible copy of everything you sign, and a signed receipt for money paid, when you sign | NRS 624.970(4) |
A repair-only job doesn't need plans or equipment lists in the contract (NRS 624.970(2)(j)). You can't sign away these rights: a clause waiving them is void (NRS 624.970(5)).
If you rent
Your landlord must keep the home habitable. That includes a water supply capable of producing hot and cold running water (NRS 118A.290(1)(c)), and plumbing in good working order (NRS 118A.290(1)(b)). The landlord can't charge you for that work, not even a home warranty copayment, unless you, your household or a guest caused the problem (NRS 118A.290(4), (5)).
If the landlord must supply hot water and willfully or negligently doesn't, and that makes the home unfit to live in, it is an essential-service problem. Give written notice. If the landlord doesn't fix it, or use best efforts, within 48 hours not counting weekends and holidays, you may buy reasonable amounts of the service and deduct it, recover damages, withhold rent, or move to comparable housing while rent stops (NRS 118A.380(1)). There are conditions. For withholding rent, for one, you must have been current on the day of your notice. Read My landlord won't make repairs before you use any of these.
If the job goes wrong
| Problem | What the law gives you | Source |
|---|---|---|
| Bad or unfinished work by a licensee | The Board can order the contractor to fix it at their cost, pay another licensee, or pay you. It can also fine them up to $10,000 | NRS 624.300(1) |
| Money lost on your own home | The Recovery Fund may pay if a licensed contractor's violation cost you. File within 4 years after the work is done | NRS 624.470, 624.480, 624.510 |
| Took your money and diverted it | A crime if the contractor willfully fails to use it for the job | NRS 624.750(4) |
| Unlicensed worker | A first offense is a misdemeanor, with a fine of $1,000 to $4,000 | NRS 624.750(2)(a) |
| A lien on your home | Someone claiming a lien generally has 90 days after finishing to record a notice of lien, or 40 days after a recorded notice of completion | NRS 108.226(1) |
The Recovery Fund doesn't pay if the license was suspended or revoked when you signed, or if you pulled the building permit yourself (NRS 624.510(2)). A contractor must tell you about the Fund in writing in the contract (NRS 624.520).

Good to know
Nevada's boiler chapter doesn't reach an ordinary home unit. It exempts a water heater that stays within 199,999 BTU per hour, 210 degrees and 120 gallons (NRS 455C.090). Behind on the gas or power bill too? See the energy help on the power outage page.
