Home Remodeling Contractors in Bainbridge Island, WA

The City of Bainbridge Island Planning and Community Development department issues building permits, and it accepts applications only as electronic submissions through its Public Permit Portal. The same portal account is used to pay fees, schedule inspections and request a consultation meeting with staff before an application is filed.

After the city deems an application complete, its initial review generally takes 30 days. Depending on the project, the Building and Planning Divisions, Public Works, the Bainbridge Island Fire Department and the Kitsap Public Health District may all review it. Inspections are booked for weekday morning or afternoon windows, and the city recommends at least 48 hours of notice.

Critical areas on the island are regulated under BIMC 16.20, updated by Ordinance No. 2018-01. The city maps them in its Critical Areas Web App, including wetlands, streams and other fish and wildlife habitat, aquifer recharge areas and geologically hazardous areas such as steep slopes.

Near the water, the Shoreline Master Program takes over. Under the city's policy on accessory structures, a shed or similar building under 200 square feet, normally exempt from a building permit, needs both a building permit and a shoreline permit when it sits within 200 feet of the shoreline jurisdiction. The same policy keeps a small backyard building exempt only when it has no plumbing, heating or living space and sits outside every zoning setback and critical area buffer; a bathroom in one needs a building permit and sewer, water or Kitsap Public Health District approval.

Where a home is on septic, the Kitsap Public Health District becomes part of the permit. If a project needs Health District approval before the building permit, the owner files a Building Clearance, which requires a permitted septic system and a designated reserve area. Adding a bedroom or an ADU beyond the system's permitted design capacity needs a Building Site Application from a septic designer or engineer.

Interior-only remodels that add no bedrooms, reroofing, and replacing windows, decks or siding do not need Health District review.

The city's ADU guidance, dated February 2026, allows one accessory dwelling unit per parcel in all residential zones, attached or detached, up to 1,000 square feet; a garage built with it does not count toward that limit. It needs one off-street parking space unless it is within 0.25 miles of a transit stop or on-street parking is sufficient, and inside the shoreline jurisdiction an ADU is conditional under BIMC 16.12. Through a countywide program the city also offers pre-approved ADU plans, the smallest 480 square feet, which city staff still review for each lot.

The Census Bureau's 2020 to 2024 American Community Survey puts the median year built at 1989, and the 1990s were the busiest decade. More than a third of homes predate 1980, some 745 predate 1940, and roughly three in four are detached single-family houses. We price the work each era calls for in writing before it starts.
