Patios & stairs in Silverdale: what to know

The building brochure says a patio typically does not need a permit when it is less than 2,000 square feet. Shoreline and critical-area buffers change that answer: the brochure requires a permit at any patio size inside them, even when the patio sits under 18 inches high. We measure each patio’s area and its position against those buffers before the quote is set.

Grading around a patio is checked separately. The county’s grading brochure, revised 7/23/2025, sets the line at 150 cubic yards or more of material moved, absent a building permit. Its exemptions include excavation below finished grade and landscape installation, and they apply where the land disturbance is less than one acre. Cut and fill around the patio is recorded on the scope either way.

Permits and rules in Silverdale

Before quoting, we check each patio’s area, its shoreline or buffer status, and its cut and fill. A patio larger than 2,000 square feet falls outside the brochure’s typical no-permit line, so we confirm its status with county staff in writing. Where a county reply is open, the estimate shows that line as pending.

Rules change and vary by parcel, so we confirm the current requirements with the city before we start.

Questions from Silverdale homeowners

What patio size stays under the typical Silverdale permit line?

The county’s building permit brochure says a patio typically does not need a permit when it is less than 2,000 square feet. Shoreline and critical-area buffers change that answer, because the brochure requires a permit at any size inside them. We check the patio’s area and location, then confirm the result with county staff before the job is scheduled.

How much cut and fill starts a Silverdale grading permit?

Kitsap County sets the line at 150 cubic yards or more of material moved, absent a building permit, in its grading brochure and in KCC 12.10.030(3). The listed exemptions include excavation below finished grade and landscape installation, and they apply where the land disturbance is under one acre. We add up the excavation and fill for the patio, including any regrading beside it.

Does a Silverdale patio inside a shoreline buffer need a permit?

Yes, at any size, according to the building brochure, which applies that rule even when the patio sits under 18 inches high. We measure the patio’s distance to the buffer line and confirm where that line sits with county staff before quoting.
