Do I need parking for a Sammamish ADU?
✓ Verified against code · August 19, 2026
Usually not: no additional space if your parcel already has four or more, and no minimum at all within a quarter mile of an existing — or even a planned — transit stop.

How current is this?
Sammamish’s ADU rules run under SMC 21.05.010.C(5) / 21.04.030.C (Sammamish Municipal Code) (Ordinance O2024-578). Sammamish's Title 21 rewrite (Ord O2024-578) took effect January 1, 2025 — six months ahead of the state deadline. Beware the city's own DADU handout: last revised September 2023, it still shows an 18-ft height limit, one-DADU cap, and two-space parking rule, all long repealed. We verified this answer against primary sources on August 19, 2026, and every change we catch is logged in the changelog.
