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

411(D) sets location standards for accessory buildings and structures separate from the yard-encroachment rules that open the same section. An accessory building attached to and made structurally part of the main house must have a common wall with it and meet every zoning requirement that applies to the main building itself, so an attached shed cannot get a smaller setback than the house it is joined to. Detached accessory buildings in the R-1, R-2, R-3, or PD zones, unless an approved precise plan says otherwise, split into two tiers.

Buildings designed for residential occupancy, or any detached accessory structure larger than 1,000 square feet or taller than 12 feet, must sit at least 10 feet from any dwelling on the same lot or an adjacent lot, and must otherwise meet the same setback requirements that apply to the primary dwelling on the lot. Smaller, non-residential structures under 1,000 square feet and under 12 feet, the kind of patio covers, gazebos, cabanas, and pool shelters homeowners typically add, get lighter standards: a walled structure needs only a 3-foot separation from the walled side to any other building on the lot, plus a 3-foot separation from any side or rear lot line.

If the structure's walls are less than 10% solid, no separation from other buildings is required except at windows, where 3 feet still applies, though the 3-foot lot-line separation remains. On a corner lot, any such structure must also meet the street side yard setback that applies to the primary dwelling.
