Edmonds, WA Building Setbacks & Zoning: Lot Coverage Limits (2026)

030(D) sets a uniform 35 percent lot coverage maximum for buildings across all three overlays of the LDR (low-density residential) zone: LDR-S, with a 6,000-square-foot minimum parent lot; LDR-M, with an 8,000-square-foot minimum; and LDR-L, with a 12,000-square-foot minimum. Unlike the setback and lot-width standards in the same table, which vary by subdistrict, the coverage limit does not scale up on larger lots; a home on a 12,000-square-foot LDR-L lot is held to the identical 35 percent ratio as a home on a 6,000-square-foot LDR-S lot.

030(A) requires that development regulations for middle housing be no more restrictive than those for detached single-family residences, including the lot coverage standard specifically named in that subsection. 030(C) unless the applicant obtains a conditional use permit allowing more. Accessory structures, garages, decks and other impervious surfaces on an LDR lot count toward the same 35 percent lot coverage figure, since the standard measures coverage by buildings and other structures on the site as a whole rather than isolating the primary residence.
