Salt Lake City Title 21A applies form-based zoning controls including height, setback, lot coverage, and bulk-plane standards that limit mansionization of small lots, especially within historic districts and traditional neighborhoods.
While SLC does not have a single ordinance titled mansionization, Title 21A imposes layered limits that achieve the same goal. Single-family residential zones cap lot coverage typically at 40 percent, set front setbacks via averaging with neighbors, and impose 28 to 35 foot height ceilings. Historic districts add design review through the Historic Landmark Commission, which scrutinizes mass, scale, materials, and roof pitch. Bonus floor area is generally not available for tear-down replacement. Recent code amendments tightened side setbacks for tall additions and required step-backs near shorter neighboring homes.
Building above the envelope triggers stop-work orders, denial of certificate of occupancy, and forced redesign or demolition of non-conforming portions. Historic district violations can stack design-review fines.
