Lake Elsinore, CA Accessory Structures: Shed & Carport Rules (2026)

LEMC § 17.76.040 divides accessory structures in the R-1 single-family district into groups with different siting rules. Group I covers sheds, children's playhouses and similar enclosures under 120 square feet with a maximum height of six and one-half feet; these small structures may be built right on the property line as long as the design complies with the City's fire and building codes, and they are also exempt from formal design review under LEMC § 17.76.140. Group II covers larger detached sheds, cabanas, workshops and similar enclosed buildings under 600 square feet with a maximum height of 15 feet, along with unenclosed carports, gazebos and patio covers; these must sit no closer than 5 feet to a side property line and 10 feet to a rear property line, and any attached, enclosed version of these structures must meet the same setback required for the main dwelling.

Group III covers enclosed structures of 600 square feet or more, which must be set back the same distance as the main dwelling unit, with straight-in entry garages sometimes required to sit even farther back. With the exception of open trellis-type patio covers and detached garages, accessory buildings generally must be located in the rear one-half of the lot and be architecturally compatible with the main dwelling. Swimming pools and spas (Group IV) are limited to rear yards or the enclosed portion of a side yard, and pool equipment within 10 feet of a property line needs a 6-foot masonry wall separating it from the neighboring lot.
