Summary
Santa Maria sets minimum front, side and rear yard depths by zoning district in Title 12. In the R-1 single-family district, front yards run 20 feet, side yards 5 and 10 feet, and rear yards 10 to 20 feet depending on building height and story count.
All yard measurements are made from the lot lines. Front Yards. Front yards shall be no less than twenty feet (20′) deep, except as follows: Garages with side entry may be set back not less than fifteen feet (15′) from the front property line. Garages with front entry shall be set back not less than twenty feet (20′), except garages with roll-up doors may be set back a minimum of eighteen feet (18′) from the property line adjacent to the street. Side Yards. On interior lots, one side yard shall be a minimum of five feet (5′) and the other ten feet (10′). On a corner lot, the setback shall be fifteen feet (15′) from the side property line adjoining the street; the other side yard shall be no less than five feet (5′). Rear Yards. For a single-story structure, the setback shall be not less than ten feet (10′). The required rear yard setback for buildings with two or more stories is twenty feet (20′) except as follows: The setback may be reduced to fifteen feet (15′) provided no more than twenty feet (20′) of the rear width of the structure is projecting into the required twenty foot (20′) setback.
Full Breakdown
09. Front yards must be at least 20 feet deep, though a side-entry garage can pull back to 15 feet and a front-entry garage with a roll-up door can sit at 18 feet instead of the standard 20. Side yards on interior lots split unevenly: one side must be at least 5 feet, the other at least 10 feet. Corner lots flip that ratio on the street side, requiring 15 feet from the side property line adjoining the street while the interior side yard drops to a 5-foot minimum; front-entry garages on corner lots still need 20 feet (18 feet with roll-up doors).
A zero side yard is possible only with an approved development plan or subdivision map that meets the combined side yard total on both adjoining lots. Rear yards depend on structure height: single-story buildings need 10 feet, while two-or-more-story buildings normally need 20 feet, reducible to 15 feet if no more than 20 feet of the rear building width projects into the setback. Rear setbacks for single- and two-story buildings can drop to 10 feet where the rear yard adjoins a flood control facility or OS (Open Space) zoned property.
R-2 medium-density lots carry a different rear yard rule: a 10-foot minimum, jumping to 20 feet where the rear yard adjoins an R-1 district, and 25 feet for alley-accessed garages and carports. 03 (Conformance) makes clear no structure may be erected, enlarged or altered except as this title specifically allows, tying every district's numeric setback to a mandatory conformance standard rather than a discretionary guideline.
Violations & Fines
Building or maintaining a structure that encroaches into a required setback violates SMMC Section 12-1.03 (Conformance) and is separately declared an unlawful public nuisance under Section 5-6.202(k), which covers any violation of the zoning ordinances or use of property outside a granted permit or entitlement. The Community Development Department enforces setback compliance at building permit review and can require plan modification, and the City may pursue nuisance abatement, including a recorded Notice of Nuisance, for encroachments discovered after construction.
