Yuma, AZ Accessory Structures: Shed & Carport Rules (2026)

Section 154-15.15 governs storage sheds, garages, workshops and similar detached buildings in Yuma's residential districts, splitting them into two tiers by size. 'Small' accessory structures, up to 200 square feet and under nine feet tall, cannot sit in the required front yard setback, and their leading edge, including any overhang, needs only a one-foot setback from the side and rear property lines, reduced to zero feet if all roof drainage is directed back onto the same lot (§154-15.15(F)(2)(b)). Height for a small shed is capped at just under nine feet, or the height of the house, whichever is less (§154-15.15(F)(2)(c)).

'Large' accessory structures, those over 200 square feet or over nine feet tall, face tighter siting rules: they must sit at least ten feet behind the front-facing corner of the main house, with a five-foot leading-edge setback from side and rear lines, reduced to three feet if the structure is unenclosed on all sides, and a maximum height of 25 feet or the height of the principal building, whichever is less (§154-15.15(F)(1)(b)-(c)). A large shed also cannot exceed 50% of the primary home's total square footage (§154-15.15(F)(1)(e)).

Every accessory structure, regardless of size, must keep a three-foot clearance on two adjacent sides for fire and emergency access (§154-15.15(D), waived for fully open shade structures), must comply with all applicable building and fire codes (§154-15.15(C)), and cannot sit inside a recorded easement without written permission from the easement holder (§154-15.15(E)).
