DIY Kitchen Remodeling in Washington: What Homeowners May Do Themselves

Washington gives homeowners a lot of room to work on their own houses. The law does not ask you to be a registered contractor, a licensed electrician or a licensed plumber to remodel your own kitchen. What it does not do is excuse you from permits, inspections or the building code. This page sets out where the lines are as of October 2026, and which answers you need to get from the permit office because we could not confirm them.

What state law lets an owner do

These are exemptions from registration and licensing only. L&I's advice is short: "If you do the work youself, you need to check which permits are required and obtain them if necessary."

Work that usually needs no permit

Inside the City of Vancouver, VMC 17.08.090(D)(1) exempts a short list of work from a building permit, including "Painting, papering and similar finish work" and "Replacement of kitchen and bath cabinets that do not require the modification of electrical or plumbing systems." Like-for-like replacement of switches and receptacles is on the city's electrical exemption list (VMC 17.16.040).

Countertops and flooring are not named in the city's exemption list. Treating them as "similar finish work" is an interpretation, so if that is your whole project, confirm it with the Permit Center. The exemption also carries a caveat in the code itself: being exempt from a permit does not authorize work that violates the technical codes.

The full table, item by item, is in whether you need a permit to remodel a kitchen in Vancouver.

Electrical work: the owner permit and its limits

You may wire your own kitchen, but "All circuit wiring" needs a permit, according to L&I, and so does most new and remodel electrical work. The rules on who buys the permit are strict:

• The person doing the work buys the permit. L&I: "Only property owners or electrical contractors can purchase an electrical permit." And: "As a property owner or homeowner, you should only purchase an electrical permit if you are doing the work yourself on your own property."
• Your name must be on the deed. L&I's owner permit application (F500-094-000, 07-2026) states: "Real estate agents, property management companies, relatives, etc. cannot purchase permits for the property owner."
• You certify how the property will be used. On that form, the owner of an existing property certifies they "will not offer the property for sale within 12 months after obtaining the property" and will do the work personally.
• Inspection has a deadline. Request inspection before covering any work, and no later than three business days after completing it or one business day after any part is energized, whichever comes first.

Plumbing, gas and mechanical work

State law does not require a license for plumbing work on your own residence, but RCW 18.106.150(3) leaves local plumbing codes in force, and plumbing permits come from the city or county. In Vancouver, moving a sink is not exempt from a permit, because the city's exemption covers only repairs that do not involve "the replacement or rearrangement of valves, pipes or fixtures" (VMC 17.08.090(D)(3)(b)). In unincorporated Clark County, the county states: "A plumbing permit is required for installation of any plumbing fixtures."

Two things we could not verify, and that you should ask before starting:

• Owner plumbing permits. The City of Vancouver's and Clark County's specific rules for owner-performed plumbing in a kitchen. The city's residential application carries the line "Licensed Plumbing Contractor required per RCW 18.106.440", so ask the Permit Center how that applies when the owner does the work.
• Gas piping and mechanical work. Whether, and on what terms, an owner may run or alter a gas line or install a ducted hood under an owner permit. Both the city and the county permit and inspect this work. Ask the City of Vancouver Permit Center (360-487-7833) or the Clark County Permit Center (564.397.4078).

Which permit covers which task is laid out in plumbing, mechanical and gas permits for a kitchen remodel.

What still needs inspection

Owner work is inspected to the same standard as a contractor's. The rule that catches people out is in VMC 17.08.140(A): work "shall remain accessible and exposed for inspection purposes until approved by the building official." You cannot close walls or set cabinets over rough wiring and plumbing that has not been approved. The city code also notes that the city is not liable for the expense of removing material "required to be removed to allow inspection".

The order of inspections and what each one looks at is in kitchen remodel inspections.

Where DIY commonly goes wrong

• Covering work before inspection. Drywall goes up over the weekend, and the rough-in has to be exposed again.
• Skipping the permit. The consequences, and how work is legalized afterward, are in unpermitted kitchen work.
• Buying a permit for someone else's work. An owner permit covers the owner's own labor. It does not cover a hired electrician.
• Hiring unregistered help. L&I warns that if you hire an unregistered person, "you could be considered that person's employer, with wage, tax, workers' comp, safety, and record-keeping requirements."
• Disturbing old materials. Paint in pre-1978 homes and old flooring, adhesives and ceiling textures in homes of any age have their own rules, even for owners. See lead paint rules and asbestos rules in Clark County.

Mixing DIY with a contractor

Splitting the job is common: the owner handles demolition, painting or the backsplash, and hired trades do the rest. A few points from the law shape how that works.

• Hiring a registered contractor does not make you one. RCW 18.27.090(11) exempts "An owner who contracts for a project with a registered contractor".
• Acting as your own general contractor is less clear. The statute's definition of contractor includes a person who, on their own property, "employs members of more than one trade upon a single job or project or under a single building permit". How that fits with the owner exemption for an owner-occupant who hires several trades directly is something we could not confirm. Check with L&I before you set a project up that way.
• Each trade pulls its own permit for its own work. Under L&I's rules, an electrical contractor you hire must buy the permit for what it installs.
• Verify everyone you pay. Each trade you hire directly should be registered, and electricians and plumbers certified. The lookup is described in how to verify a contractor in Washington.
• Put the split in writing. A contractor's warranty and schedule will normally cover only its own work, so the contract should say which tasks are yours and when they must be finished.
