Building permits in Kitsap County are handled by Permit Services, Kitsap County Department of Community Development. Washington has a statewide building code framework adopted by the State Building Code Council, while cities and counties manage local permit intake, plan review, fees, and inspections.
This guide covers what requires a permit, how to apply through Kitsap Online Permit Center, permit fees, trade permits, and inspections - so your Washington project can move from submittal to approval with fewer correction cycles.
Confirm the authority having jurisdiction before filing. This guide covers unincorporated Kitsap County. Bainbridge Island, Bremerton, Port Orchard, and Poulsbo may route city projects separately. Washington cities and counties often split building, planning, fire, public works, utilities, septic, shoreline, and critical-area approvals across different offices.
Washington is a statewide code state. Local jurisdictions enforce the Washington State Building Code and applicable state amendments, plus local zoning, land-use, shoreline, floodplain, energy, fire, utility, and development standards. Commercial, multi-family, and engineered scopes may require Washington-licensed design professionals.
Kitsap County uses separate online steps for new applications and for later tracking, payments, reviews, and approved documents, so account setup and record handoff must be managed carefully.
What requires a building permit in Kitsap County?
Under the Washington State Building Code and local ordinances, a permit is required before most construction, alteration, demolition, repair, relocation, occupancy change, and trade work begins.
Permit required
- New residential, commercial, industrial, and mixed-use construction
- Additions, structural alterations, tenant improvements, conversions, and change of occupancy
- Structural repairs, seismic work, decks, porches, garages, carports, and many accessory structures
- Electrical service changes, panel upgrades, EV chargers, solar PV, generators, and permanent wiring
- Plumbing, water heaters, repipes, sewer connections, gas piping, and fixture relocations
- Mechanical equipment, HVAC replacements, ductwork, commercial hoods, and exhaust systems
- Demolition, signs, grading, retaining walls, shoreline/floodplain work, and right-of-way work where applicable
Typically exempt
- Painting, papering, tiling, carpeting, cabinets, countertops, and similar finish work
- Minor repairs that replace like-for-like materials without structural or system changes
- Small detached accessory structures below the local exemption threshold and without utilities
- Some fences, patios, and non-structural site work, subject to zoning and local limits
Exemptions are narrow. Zoning, setbacks, easements, critical areas, shoreline rules, floodplain, historic review, or HOA requirements may still apply even when a building permit is not required.
Get the permit issued before starting work. Work without a permit can lead to correction notices, stop-work orders, doubled or investigative fees, required engineering, or removal of unapproved work.

Kitsap County trade permits
Electrical, plumbing, mechanical, fire, and specialty scopes may require separate permits and registered or licensed trades. Some trade permits can be pulled independently, while others must be tied to a building permit or plan-review record.
Electrical permits
Required for electrical services, feeders, panels, branch circuits, EV chargers, solar PV, generators, and most permanent wiring. Washington L&I or the local electrical authority may administer electrical permits depending on the jurisdiction.
Plumbing & gas permits
Required for water, waste, vent, fixtures, backflow, water heaters, sewer, and gas piping work. Septic or onsite sewage review may be separate for rural properties.
Mechanical permits
Required for HVAC equipment, ductwork, ventilation, commercial hoods, gas appliances, exhaust systems, and similar mechanical scope.
Specialty permits
Depending on scope, projects may also need demolition, sign, fire alarm/sprinkler, grading, erosion control, critical-area, shoreline, floodplain, right-of-way, driveway, tree, or public works permits.
Verify Washington registration before filing. Most paid construction work requires active Washington Department of Labor & Industries contractor registration, bond, and insurance. Permit applications should match the contractor, registration, owner, scope, and valuation.
