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

Beaumont Municipal Code § 17.03.060, the Residential, Single-Family Zone (R-SF Zone) section, names sheds outright. Paragraph C.2.d says accessory structures, including second and guest units, detached garages, outbuildings, sheds, gazebos, and patios, must comply with the front and side setback regulations for the R-SF Zone and can be located in the rear yard areas only under four limits. The front yard minimum is 20 feet. Interior side yards cannot be less than five feet on each side, except that interior lots 70 feet or more in width need five feet on one side and ten feet on the other. Corner lots carry a street side yard of at least ten feet from each side yard property line.

The four rear-yard limits are specific. The height of any accessory structure cannot exceed the height of the principal residence on the site. A single-story accessory structure sits at least ten feet from the principal residential structure, and a two-story one at least 20 feet away. A minimum rear setback of ten feet applies to every accessory structure. The structure, or the total of all accessory structures, can never occupy more than 25 percent of the lot.

Where a lot adjoins the R-C (Recreation/Conservation) Zone, the same section requires a 20-foot setback along the property line shared with that zone. The section also caps a main building at 35 feet or two stories, whichever is less, and a shed cannot rise above the house it serves. When a setback or classification question is unclear, Section 17.02.130(B) makes the Community Development Director responsible for gathering the facts and issuing a written interpretation, and the Director can refer the matter to the Planning Commission.
