Silverdale county permit lines and open questions
Kitsap County’s building permit brochure, revised 12/11/2025, requires a permit for a non-shoreline wall over 4 feet high. The exemption covers only upland, non-shoreline walls of 4 feet or less, taken from the footing’s underside up to the wall’s top edge, that carry no surcharge such as a road, building, or tank, or any combustible or flammable liquid. The same brochure requires a permit for a driveway or sidewalk slab rising more than 30 inches over grade or spanning a lower story or basement. On shoreline parcels that line drops to 18 inches.
The grading brochure, revised 7/23/2025, sets the permit line at 150 cubic yards or more of material moved, absent a building permit, and KCC 12.10.030(3) uses the same figure. Stormwater follows KCC 12.20.010: the first five requirements apply once new and replaced hard surface reaches 2,000 square feet, or land disturbance reaches 7,000 square feet.
Driveways that connect private property to a county road need a county road approach permit from Kitsap County DCD. The county right-of-way brochure requires a permit to construct, alter, repair, or relocate any utility or roadway feature in county right-of-way, and it does not mention driveways, curbs, or sidewalks.
