Clark County sits opposite Portland across the Columbia and is the fifth most populous county in Washington. Its permit floor is markedly lower than most of the state — work that is routinely exempt elsewhere is permitted here as a matter of course.
The Building Safety programme reviews and inspects all construction requiring building permits in unincorporated Clark County and in the town of Yacolt, from small residential remodels to multi-storey commercial buildings, with applications through the county land management system.
This guide covers unincorporated Clark County and the town of Yacolt, which the county also permits. Vancouver, Battle Ground, Camas and the other incorporated cities permit separately, though the state issues electrical permits in several of them.
Re-roofing, siding and windows are all permitted work. The county states that re-roofing permits are required for all buildings in Clark County, and that a permit is required to replace any windows or siding on a structure. Generally a maximum of two layers of roofing may be applied to a residential structure, and a separate permit may be required where structural work such as replacing roof sheathing is involved.
What requires a building permit in Clark County?
Washington has a mandatory statewide building code. The codes enumerated in chapter 19.27 RCW, the State Building Code Act, are adopted and amended by the State Building Code Council within the Department of Enterprise Services, and they are required in all cities and counties — local government administers and enforces them rather than deciding whether to have them. A city or county may amend the state code, but it amends upward from a floor it cannot opt out of. So the question in Clark County is not whether a code applies, but which edition is in force and what Clark County Community Development has added to it.
Permit required
- New buildings, additions, alterations and change of occupancy or use
- Structural alterations, load-bearing changes, foundations, decks and retaining walls
- Plumbing work under the Uniform Plumbing Code as adopted by the state
- Mechanical and HVAC change-outs, fuel gas work and ventilation
- Work affecting the Washington State Energy Code envelope or systems
- Re-roofing above the exempt scope, demolition, and work in critical areas
Often exempt
- Ordinary repairs and maintenance replacing materials in kind
- Small accessory structures below the code threshold, where zoning allows
- Painting, flooring, cabinetry and other finish work
- Like-for-like fixture swaps with no alteration to piping
Local amendments, fee schedules and exempt thresholds differ from one jurisdiction to the next, so an exempt list from a neighbouring city is not reliable. An exemption from a building permit is never an exemption from zoning, critical areas review, the energy code or a trade permit. Confirm scope with Clark County Community Development before work starts.
Your electrical permit almost certainly does not come from the city. For most of Washington, electrical permits are issued and electrical inspections are carried out by the Electrical Program at the Department of Labour and Industries under chapter 296-46B WAC — not by the local building department. A minority of cities run their own electrical programme instead. Establish which applies to the parcel before you assume a single counter handles everything, because the electrical track runs on its own timetable and its own inspector.
The statewide features that catch projects everywhere
Four things shape a Washington filing more than the model code does. First, the edition is set by the state on a three-year cycle and adopted in two groups over a two-year timeline, so the building, residential, mechanical and plumbing parts do not all arrive on the same day. Second, plumbing runs on the Uniform Plumbing Code as adopted by the state, not the International Plumbing Code that most of the country uses. Third, the Washington State Energy Code is its own code under chapter 19.27A RCW rather than the international energy code, and it is among the most demanding in the country. Fourth, growth management and critical areas regulation reach ordinary residential work near wetlands, steep slopes, streams and shorelines far more often than owners expect. Cascadia subduction zone seismic detailing applies statewide. Retaining walls carry an engineering requirement with no exceptions: a permit is required for walls over four feet measured from the bottom of the footing to the top, or for any wall supporting a load such as a slope, driveway or footings — and engineering by a Washington State registered engineer is required for all retaining walls requiring a permit, whatever the size or circumstances
Who handles permitting in Clark County?
Building Safety reviews and inspects all construction projects requiring building permits in the unincorporated areas of Clark County and the town of Yacolt, with development engineering, fire marshal and code enforcement functions running alongside within Community Development.
| Detail | Information |
|---|---|
| Department | Clark County Community Development, Building Safety |
| Address | Public Service Center, 1300 Franklin Street, Third Floor, Vancouver, WA 98660 |
| Community Development | (564) 397-2375 |
| Building Safety | (564) 397-4912 |
| Counter | In-person services by appointment only, arranged by email |
| Also permits | The town of Yacolt as well as unincorporated county |
| Electrical | State Labour and Industries, covering the county, Battle Ground, Yacolt and La Center |
| Processing times | Published as a rolling twelve-month average by permit type |
The counter is not a walk-in service. All in-person services at the Permit Center require an appointment, scheduled by email, with staff otherwise available by phone and email and the county encouraging online services. It asks for the permit, case or licence number, the address and the parcel number on any enquiry, which speeds a response considerably.
The county publishes something few jurisdictions do: average permit processing times by permit type on a rolling twelve-month basis. That is a real planning input rather than a target, because it reflects what actually happened rather than what the department intends, and it can be checked before committing to a programme date.
Permit types
Residential permits
Residential permit categories are unusually granular, with separate permit types for demolition, fences and retaining walls, mobile home placement including temporary hardship permits and six-month staging, and miscellaneous matters such as address assignment and agricultural structure exemptions. Manufactured and mobile home demolition goes to the state rather than the county.
How Washington contractor credentials work
Washington registers contractors rather than licensing them. Under chapter 18.27 RCW every contractor must register with the Department of Labour and Industries, file a continuous surety bond — thirty thousand dollars for a general contractor, fifteen thousand for a specialty contractor — and keep liability insurance on file. Registration runs for two years and carries no continuing education requirement at the base level. Crucially, registration is not a competence test and it does not authorise trade work: electrical work requires certification under chapter 19.28 RCW and plumbing under chapter 18.106 RCW, each with its own examination and its own programme office.
A general registration does not let anyone touch the wiring or the pipes. A registered general contractor must subcontract electrical and plumbing work to appropriately certified trades, and an electrical contractor licence additionally requires at least one certified electrician on staff. Verify the registration is active and the bond and insurance current with Clark County Community Development and with the department, because registration lapses are common and an expired registration invalidates the credential the permit relies on.
Commercial permits
Commercial work runs through electronic plan review with its own file requirements. Because the state issues electrical permits in unincorporated Clark County and in Battle Ground, Yacolt and La Center, the electrical scope on a commercial project is invoiced and inspected outside the county process entirely.
Registrations, trade certifications and design professionals
Three credential layers appear on Washington projects: the state contractor registration under chapter 18.27 RCW, which nearly everyone doing the work needs; separate state trade certification for electricians and plumbers, each examined and administered by its own programme; and, on commercial and larger residential work, drawings stamped by a Washington-licensed architect or professional engineer. Confirm what Clark County Community Development requires for the specific building before filing.
Clark County permit costs and fees
Clark County fees are based on project valuation on a similar structure to the incorporated areas nearby, with the published rolling processing times available alongside to plan the calendar as well as the budget.
| Fee component | How it works |
|---|---|
| Building permit | Set by the local jurisdiction, usually on project valuation; the state sets the code, not the fee |
| Plan review | A percentage of the permit fee or a flat charge, set locally |
| Plumbing and mechanical | Separate local permits under the adopted plumbing and mechanical codes |
| Electrical | Usually a state permit fee through the Labour and Industries Electrical Program, not a city fee |
| Energy code | Compliance documentation for the Washington State Energy Code, and review time for it |
| Critical areas and land use | Separate review and fees where wetlands, slopes, streams or shorelines are involved |
Washington sets the code statewide but leaves the fee schedule local, so two jurisdictions on the same edition can price the same project very differently. The electrical fee is the one that most often surprises people, because on most projects it is paid to the state rather than to the city. Ask Clark County Community Development for the schedule in force on your filing date, and confirm the electrical route separately.

Trade permits and who may pull them
Trade permits are separate from the building permit and, in Washington, are not all issued by the same body. Plumbing and mechanical permits come from the local jurisdiction under the codes the state has adopted. Electrical permits come from the Electrical Program at the Department of Labour and Industries, unless this jurisdiction runs its own. That split is the single most common source of confusion on a Washington project.
Your electrical permit almost certainly does not come from the city. For most of Washington, electrical permits are issued and electrical inspections are carried out by the Electrical Program at the Department of Labour and Industries under chapter 296-46B WAC — not by the local building department. A minority of cities run their own electrical programme instead. Establish which applies to the parcel before you assume a single counter handles everything, because the electrical track runs on its own timetable and its own inspector.

How to apply for a Clark County building permit
Re-roofing on all buildings, and any siding or window replacement, all require permits here.
A Washington State registered engineer is required for all retaining walls that need a permit.
In-person services at the Permit Center are by appointment only, arranged by email.
Averages by permit type are published on a rolling twelve-month basis.
The state issues electrical permits in unincorporated Clark County and three of the incorporated towns.
Separate types cover demolition, fences and retaining walls, mobile homes and miscellaneous approvals.
Review, corrections and what actually causes delay
In Washington the first cause of delay is the energy code, because the state code is its own instrument and more demanding than the international one most designers default to. After that comes critical areas review, which reaches ordinary residential work near wetlands, streams, steep slopes and shorelines and adds its own study and mitigation timeline. Then the electrical split, where a project waits on a city inspection that was never going to happen because the electrical permit sits with the state. Then edition confusion, because the state adopts in two groups and the parts do not all move together. Build review time into the schedule and confirm the checklist with Clark County Community Development before filing.
Approvals do not stay live indefinitely. Permit validity periods are set locally on top of the state code, so they differ between neighbouring jurisdictions and cannot be assumed from a previous job. On phased or financed work, confirm the expiry window and keep the permit alive with progress inspections.
Inspections in Clark County
Where a permit is required, standard checkpoints include footing and foundation, framing, rough-in plumbing and mechanical, insulation and energy code compliance, fire systems on commercial work, and final, with a certificate of occupancy before the building is used. Because the county permits the town of Yacolt as well as unincorporated areas, the same inspection service covers both, which is worth knowing on a project near that boundary.
The point to plan around is that the electrical inspections may be booked with a different body entirely. Where the state Electrical Program holds the electrical permit, its inspector attends on the state’s schedule and the local inspector will not sign off electrical work. Sequencing a cover-up around two independent inspection queues is the practical skill on a Washington job.
Do not cover work before the required inspection has been approved. Keep the issued permits — plural — the approved plans and the energy code documentation available on site.
Clark County permit search and official resources
Permit records in Washington are split the same way the permits are. Where Clark County Community Development is the authority for unincorporated Clark County, it holds the building, plumbing and mechanical records — but the electrical record for most projects sits with the state Electrical Program instead. If you are buying, refinancing or renovating, check both, because a clean local record does not mean the electrical work was ever permitted.
Confirm the edition, the local amendments and the electrical route. Washington sets a mandatory statewide minimum under chapter 19.27 RCW, but the edition moves in two groups on a three-year cycle and every jurisdiction may amend upward. All three questions have to be answered for the parcel and the filing date.

Frequently asked questions
Do I need a permit to re-roof?
Yes. The county states that re-roofing permits are required for all buildings in Clark County, with no size threshold, and that a separate permit may be required where structural work such as replacing roof sheathing is necessary. Generally a maximum of two layers of roofing may be applied to a residential structure.
What about siding and windows?
Both are permitted work. A permit is required to replace any windows or siding on a structure, which is a materially lower threshold than most Washington jurisdictions apply.
Does my retaining wall need an engineer?
If it needs a permit, yes. A permit is required for retaining walls over four feet measured from the bottom of the footing to the top, or for any wall supporting a load such as a slope, driveway or footings, and engineering by a Washington State registered engineer is required for all retaining walls requiring a permit.
Can I just come to the counter?
No. All in-person services at the Permit Center require an appointment, arranged by email, with staff otherwise available by phone and email.
Which code edition applies?
The state edition as amended by the county. Washington has a mandatory statewide building code. The codes enumerated in chapter 19.27 RCW, the State Building Code Act, are adopted and amended by the State Building Code Council within the Department of Enterprise Services and are required in all cities and counties, so local government administers and enforces them rather than choosing whether to have them. The two thousand twenty-one editions took effect on the fifteenth of March, two thousand twenty-four after two delays, and the two thousand twenty-four editions are dated to take effect on the third of May, two thousand twenty-seven. Adoption runs in two groups over a two-year timeline, so the building, residential, mechanical and plumbing parts do not all move on the same day. A city or county may amend upward from the state minimum but cannot opt out of it.
Who issues my electrical permit?
The state, in unincorporated Clark County and also in Battle Ground, Yacolt and La Center. Washington registers contractors rather than licensing them. Under chapter 18.27 RCW a contractor registers with the Department of Labour and Industries, files a continuous surety bond of thirty thousand dollars as a general contractor or fifteen thousand as a specialty contractor, and keeps liability insurance on file, renewing every two years. Registration is not a competence test and does not authorise trade work: electrical certification comes under chapter 19.28 RCW and plumbing under chapter 18.106 RCW. The electrical permit itself usually comes from the state rather than the city, because the Electrical Program at Labour and Industries issues electrical permits and carries out electrical inspections for most of Washington under chapter 296-46B WAC.
