Bathroom Remodel Permits & Code in Clark County, WA: The Complete Guide

The three-part test: what actually triggers a permit

Every jurisdiction in Clark County administers the same underlying rulebook — the Washington State Building Code, the state's adopted version of the International Residential Code — so the technical trigger for a bathroom permit is consistent even though the office you file with is not. Three categories of work reliably cross the line:

• Plumbing moves — relocating a toilet, sink, or shower/tub drain and supply lines, or adding a fixture, rather than reconnecting one in its existing location.
• Electrical work — adding or rewiring circuits, new outlets or lighting, or upgrading exhaust-fan wiring. This piece is permitted by the state, not the city or county building counter.
• Structural or mechanical changes — removing or altering a wall (load-bearing or not), reframing for a curbless shower pan or recessed niche, or changing ventilation/mechanical systems.

Incorporated cities vs. unincorporated Clark County — who you actually file with

This is the detail people get wrong most often: Clark County is large, but most of its population lives inside incorporated cities that run their own building departments entirely separate from the county. If your address is inside Camas, Vancouver, Battle Ground, Washougal, Ridgefield, or La Center, your permit goes to that city — not to the county — even though the city sits inside Clark County's borders.

Clark County's own Community Development department only issues permits for unincorporated land: areas like Salmon Creek, Hazel Dell, Orchards, Felida, and Brush Prairie that fall outside every city boundary. The county runs its own online system, the Land Management System (CC LMS), separate from any city's permitting portal.

How the application and review process works

The mechanics differ slightly by office, but the shape is the same everywhere: submit an application (usually online), the reviewing agency checks it against the Washington State Building Code and any local amendments, corrections get sent back if something's missing, and a permit issues once fees are paid and plans are approved.

Vancouver's process runs through five stages — submission, prescreen, plan review, approval, issuance — with plan review commonly taking 4–6 weeks for a moderate remodel. Battle Ground runs a comparable four-stage process through its Customer Self Service portal. Camas manages the same flow through its own online system. Clark County's unincorporated-area applications go through CC LMS. In every case, the office reviewing your plans is checking the same core things: does the plumbing layout meet code, is the electrical load and wiring method acceptable, does any structural change maintain the required framing and fire separation, and is ventilation adequate for the space.

Inspections: what gets checked and when

A permit isn't a one-time stamp — it comes with a schedule of required inspections tied to construction milestones, and the job isn't legally finished until a final inspection closes it out. For a typical bathroom remodel that involves plumbing and electrical, expect inspection points roughly in this order: rough-in plumbing and electrical (before walls close up), any framing/structural inspection if a wall was altered, a waterproofing or shower-pan inspection where applicable, insulation (if exterior walls were opened), and a final inspection covering fixtures, GFCI/AFCI protection, and ventilation.

Every jurisdiction in the county schedules and tracks inspections through its own online account tied to the permit — Vancouver posts results to the applicant's account, Battle Ground uses an inspection card system, and Clark County tracks them through CC LMS. Skipping a required inspection, or covering work before it's signed off, is one of the most common reasons a remodel stalls at resale, since an uninspected permit shows up as open in a title search.

Fees: budget for them, but expect a range, not a fixed number

Every jurisdiction here prices permits off the value of the work rather than a flat rate — Camas publishes a fee schedule alongside its Impact & System Development Charge schedule, Vancouver calculates and communicates plan review fees after receiving an application since cost scales with project valuation, and Clark County describes its permit fees as "project specific fees for review and inspection services." None of them publish a single number that applies to every bathroom remodel, because a plumbing-only permit and a permit involving a structural wall move are priced differently.

The practical takeaway: budget permit fees as a small percentage of the overall project cost, and get the actual number from the jurisdiction's published fee schedule (or from your contractor, who pulls the permit) rather than assuming a flat figure. Our bathroom remodel cost guide covers how permit and plan-review costs typically fit into an overall project budget.

Why licensed matters: contractor registration and who's liable

Washington requires anyone performing construction work for someone else — plumbing, electrical, or general contracting — to be registered with the Department of Labor & Industries under RCW 18.27, which requires a surety bond and liability insurance. The one carve-out is RCW 18.27.090: a homeowner can do work on the personal residence they occupy without registering, as long as the work isn't being done to prepare the home for sale, demolition, or lease.

The law also puts a verification duty on the permitting agency itself — RCW 18.27.110 requires whoever issues the building permit to confirm the listed contractor is currently registered before the permit is issued. That's a backstop, not a substitute for your own diligence: use L&I's free Verify tool to check a contractor's registration, bond, insurance, and citation history before signing anything, in any Clark County jurisdiction.

An unlicensed contractor pulling a permit under someone else's registration, or skipping the permit altogether, isn't just a paperwork problem — it removes the state-mandated bond and insurance protection the registration system exists to provide, and it can leave a homeowner personally on the hook if the work fails inspection or causes damage down the line.

A quick way to self-check your project

• Is a sink, toilet, tub, or shower moving to a new location, or is a new fixture being added? → Plumbing permit, filed with your city or (if unincorporated) Clark County.
• Is a new circuit being added, or is wiring being altered — including exhaust fan or heated-floor wiring? → Electrical permit, filed with WA L&I regardless of city or county.
• Is any wall being removed, moved, or opened for framing (including recessing a curbless shower pan)? → Structural/building permit, filed with your city or county.
• Is ventilation or mechanical equipment changing? → Mechanical permit, same jurisdiction as your building permit.
• None of the above, and everything is staying in its existing footprint? → Likely no permit required, but confirm with your jurisdiction before assuming.

How Camas Bath handles this

Because the right office depends on the address, and the right permit type depends on scope, we determine both up front — city building department, Clark County Community Development, or WA L&I for electrical — and pull, submit, and manage the required permits and inspections as part of every full bathroom remodel, accessible bathroom, or wet room conversion project across Camas, Vancouver, Washougal, Battle Ground, Ridgefield, and the unincorporated Salmon Creek and Hazel Dell areas.
