Lakewood, WA Building Setbacks & Zoning: Setback Rules (2026)

030(A), which lists zones across the top, from single-family R1 through the densest multifamily zone MF3, and dimensional standards down the side. Front yard/street setbacks are 15 feet in R1 and R2, drop to 10 feet in R3, R4, and the MF zones, and fall to just 5 feet in the MR1 and MR2 zones. Every zone shares a 20-foot garage or carport setback, so a vehicle can park in the driveway without hanging over the sidewalk, and a 25-foot setback along any principal arterial or state highway regardless of the zone's ordinary front yard figure.

Rear yards without an alley run 15 feet for one to three units in R1/R2, dropping to 10 feet for larger buildings or in R3 and R4, while a rear yard fronting an alley needs no setback at all under (B)(3). Interior setbacks split by construction type in the single-family zones: 0 feet for an attached wall, 5 feet for a detached structure, while the MF1 through MF3 zones use a flat 8-foot interior setback regardless of attachment. 090(B) governs how these lines are measured and applied, including a 20-foot rule for flag lots and a requirement that corner lots provide a front yard setback on every street frontage. 030(C)(1) to preserve a significant or heritage tree, provided the reduced line stays at least 3 feet from the property line. 090(B)(11).
