Summary
Residential structure height in San Diego is capped by an angled building envelope plane keyed to lot width and zone, not a single flat number citywide, per SDMC §131.0444.
Maximum structure height shall not exceed the height of the angled building envelope plane, which connects the maximum structure height adjacent to the setback and the overall maximum structure height as determined by the underlying base zone... For buildings with a slab foundation, the maximum permitted structure height is 21 feet for one- and two-story structures or 31 feet for three-story structures. For buildings with a conventional raised floor, the maximum permitted structure height is 25 feet for one- and two-story structures or 35 feet for three-story structures.
Full Breakdown
San Diego's residential zones cap height with an angled building envelope plane rather than one flat limit. The plane's angle depends on lot width under Table 131-04H, and the maximum structure height itself varies by base zone: RS/RX zones top out near 24 feet at the setback line, RT zones at 21-35 feet depending on foundation type and story count (30-degree plane above 27 feet), RM-1 zones at 30 feet, and RM-2 zones at 40 feet. Encroachments above the envelope require approval under §131.0461.
Violations & Fines
Building without Development Services approval that exceeds the angled envelope plane or the zone's maximum structure height triggers a code enforcement stop-work order and requires a permit modification or discretionary Neighborhood Development Permit to resolve.
