Summary
A shed or other one-story accessory building on an R-1 lot in Gardena must sit at least four feet from the rear and side property lines when it stands in the rear third of the lot. Garages get a break: they may go right on the rear or side line in that same rear third, but a garage facing a public street still needs a twenty-foot front setback.
4. Accessory buildings: one-story accessory buildings, other than a garage, shall be set back four feet from the rear and side property lines when located in the rear one-third of the lot. Garages may be constructed along the rear and side property line when located in the rear one-third of the lot. Garages fronting on public streets shall maintain a minimum twenty-foot yard setback. All garages shall be provided with garage doors and new front facing garages and replacement garage doors for front facing garages shall be sectional type doors.
Full Breakdown
Section 18.12.050(G)(4) of the Gardena Municipal Code sets the yard rules for accessory buildings in the R-1 single-family zone. A one-story accessory building other than a garage, the category covering a garden shed, workshop or detached storage structure, must be set back four feet from the rear and side property lines whenever it is located in the rear one-third of the lot; outside that rear third, the building must instead meet the standard side setback of five feet for an interior lot or ten feet for a corner lot's street side, and the standard rear setback of ten feet for new construction or five feet for an existing single-story dwelling, set out in Section 18.12.050(G)(1) through (3).
Garages are treated differently: a garage may be built directly on the rear or side property line when it sits in the rear one-third of the lot, but any garage fronting a public street must still keep a twenty-foot front yard setback, and all garages, front-facing new construction and replacement doors alike, must use sectional-type garage doors. Section 18.12.050(H) also requires a minimum six feet of separation between the main house and any accessory building. A shed or garage counts toward the lot coverage cap in Section 18.12.050(I), fifty percent for an interior lot or seventy-five percent for a corner lot, and toward the fifty-percent front-yard hardscape limit in Section 18.12.050(G)(5) if it sits within that area.
Violations & Fines
Building an accessory structure that violates the Section 18.12.050 setback, coverage or separation standards is a code violation under Section 1.16.010, chargeable as a misdemeanor punishable by a $1,000 fine and six months in jail, or, at the city attorney's discretion, as an infraction with escalating fines of $100, $200 and $500 for repeats within a year. Code enforcement may also issue a Chapter 1.20 administrative citation.
