When does a sign need a permit in Sammamish?
Each city's own sign code, usually a chapter of its zoning or development code, decides which signs need a permit and sets their size, number and placement by zone. Putting up or structurally altering a permanent sign generally needs a city sign permit, plus an electrical permit if the sign is lit, while repainting, ordinary maintenance and copy changes generally do not. Which small or temporary signs need no permit, and up to what size, differs from city to city, so check the city's own list before ordering a sign.
