Bellevue FAQ
Do I need a permit for my Bellevue outdoor kitchen?
Only if it involves utility connections (gas, water, sewer, dedicated electrical) or a roof/canopy structure. A pre-fabricated movable grill on a patio with no plumbed lines does not need a permit. As soon as you tap gas or water, you need separate plumbing and gas permits through MyBuildingPermit.com plus an L&I electrical permit.
Which codes apply to a Bellevue outdoor kitchen?
The 2021 I-Codes as adopted by the Washington State Building Code (WAC 51-50, 51-51) and amended by BCC Title 23. The fire code provisions in BCC 23.11 govern clearances to combustibles. Setbacks follow the underlying zoning district under LUC 20.20.
Seattle FAQ
Do I need a permit for a built-in outdoor kitchen in Seattle?
Yes if it has any gas line, plumbing, electrical, or roof. SDCI requires a building permit under SBC 105. Counter-only assemblies with no utility connections may not need one.
How close to the property line can my outdoor kitchen be?
Default setbacks in Neighborhood Residential zones are 5 ft sides and 25 ft rear under SMC 23.44.014. Outdoor kitchens count as accessory structures and cannot encroach into required setbacks.
Can I do my own gas line for my outdoor kitchen?
Gas piping work requires a licensed gas-piping contractor and a Seattle Fuel Gas Code permit. The line must be pressure-tested under SFGC 406 before commissioning.
