Full Breakdown
040. Attached accessory structures must meet the same setbacks and height limit as the primary building. Detached accessory buildings are treated differently depending on where they sit on the lot. In the front half of a lot, a detached shed or accessory building must meet the same setback as the primary building for the zone. In the rear half, a detached accessory building of 450 square feet or less may encroach into the interior side and/or rear yard setback all the way to the property line.
Only one such encroaching building is allowed on lots of 6,000 square feet or smaller; two are allowed on larger lots if separated by at least 10 feet. A detached accessory building over 450 square feet must meet the full setback of the underlying zone, and no detached accessory building or structure may sit within five feet of an alley. Height is capped at 15 feet for detached accessory structures and buildings in the front half of the lot. 110. On corner or reverse corner lots, the exterior side setback follows the front yard setback of the adjacent key lot.
Nonresidential lots must keep detached accessory buildings at least five feet from the primary building. Property within San Clemente's Coastal Zone faces an added layer: a Coastal Development Permit under the certified Local Coastal Program is required before an accessory structure near the shoreline can be built, on top of these Title 17 standards.
Violations & Fines
Building without a permit or in violation of these setback and height standards is enforceable as a zoning violation under the City's general penalty, Section 1.16.010: a misdemeanor punishable by a fine up to $1,000, up to six months in county jail, or both, unless the City elects to prosecute as an infraction, which carries escalating fines of $100, $200 and $500 for repeat offenses within a year. Each day the violation continues is a separate offense.
