Sammamish, WA Parking Rules: Driveway Rules (2026)

Driveway design and placement in Sammamish are governed by the Sammamish Development Code (Title 21, Section 21.07.080, Development Standards - Parking and Circulation). Driveways providing ingress and egress between off-street parking and abutting streets must be designed, located and built per the City of Sammamish public works standards adopted by SMC 21.08.010. Driveways for most developments may cross or sit within required setbacks or landscaped areas to reach off-street parking, provided no more than 10 percent of required landscaping is displaced and the driveway is no closer than five feet from any property line. Driveway lanes may be no wider than 11 feet per entry or exit lane unless the director finds wider lanes appropriate and not harmful to circulation, stormwater, safety, pedestrians or visual quality. On the street side, SMC 46.30.070 adopts RCW 46.61.570, which prohibits stopping, standing or parking in front of a public or private driveway and within five feet of the end of the curb radius leading to a driveway, and bars parking on sidewalks and planting strips. Blocking a neighbor's or your own driveway from the street is therefore an enforceable parking violation.
