Spokane controls oversized infill homes through SMC Chapter 17C lot coverage, building height, and floor area regulations rather than a dedicated mansionization ordinance, with stricter limits in residential single-family RSF and historic overlay zones.
Unlike Los Angeles, Spokane has not adopted a stand-alone mansionization ordinance. Instead SMC Chapter 17C combines maximum building heights, lot coverage caps, and required side and rear yards to limit how much home can fit on a residential lot. Most RSF zones cap height around thirty-five feet and lot coverage near forty to forty-five percent. Historic districts including Browne's Addition and the South Hill historic overlay layer additional design review through the Spokane Historic Landmarks Commission. Recent Comprehensive Plan updates allow more middle-housing forms (duplex, triplex) instead of larger single-family mansions on infill lots.
Exceeding height, coverage, or setback limits can produce stop-work orders, code-enforcement civil penalties, and required redesign or removal before final inspection or occupancy.
