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

19, Accessory Uses and Structures, treats a storage shed as an accessory structure clearly incidental to the primary residence. 37 and defined guest houses. 050 supplies the dimensional standards for residential zones: excluding detached garages, carports, spas, and pools, accessory structures (which include sheds) cannot exceed 10 percent of the lot area or 1,000 square feet total, whichever is smaller, an aggregate cap that applies across every accessory structure on the property combined. Height tops out at 15 feet, and a shed is limited to one story with no second floor allowed.

Placement rules matter as much as size: a shed cannot sit in the front yard or in any part of the side yard that projects between the house and the front property line, except for a decorative entry feature. It needs at least 7 feet of separation from the main house and 6 feet from any other accessory building, plus a minimum setback from the side or rear property line of 3 feet if it has no openings facing that line, or 5 feet if it does.

Sheds must also be architecturally compatible with the main house, and metal shipping-style storage containers designed to carry freight are banned outright under subsection (A). 030(E) separately requires accessory structures to meet the Building Code's minimum fire-safety setbacks between buildings, layering a construction-code requirement on top of the zoning dimensional standards.
