Carports in Redmond must meet setback and lot coverage rules under RMC 21.08, typically require a building permit for permanent roofed structures, and generally cannot encroach into required front yard setbacks.
Carports in Redmond are treated as accessory structures under RMC 21.08 and require a building permit when they are permanent roofed structures attached to columns or posts regardless of whether the sides are enclosed. Typical residential zone rules require carports to observe front, side, and rear yard setbacks the same as garages, though some zones allow detached carports to encroach into rear yards to within 5 feet of the property line. Height is limited to the zones accessory structure maximum (typically 15 feet). Carports count toward lot coverage calculations. Temporary fabric car canopies used seasonally are generally not regulated if easily removable, but must not obstruct sight triangles. Converting a carport into an enclosed garage requires a new building permit. In critical areas, new impervious surfaces including carport roofs are restricted under RMC 21.64. HOA covenants may impose additional architectural review.
