Alhambra, CA Accessory Structures: Carport Rules (2026)

The City of Alhambra lists carports among the detached accessory structures (with garages, sheds, workshops, gazebos and covered patios) governed by its residential development standards under Title 23 of the Zoning Code. Per City guidance, accessory structures may not exceed a height of 15 feet and must be set back a minimum of three feet from any interior side or rear lot line. Structures under 4 feet tall may sit within a street-side setback but no closer than 3 feet to the lot line. Accessory structures collectively may not occupy more than 40 percent of the required rear-yard setback area, which constrains how much covered parking and other structures can fill the back of a lot. A carport may only be built on a lot that already has a permitted main building. New carports and expansions are generally subject to Minor Site Plan Review, and Design Review Board approval may be required depending on the project type, location and zone district. Because carports are roofed structures, a building permit is normally required in addition to zoning clearance. Note that when required covered parking is involved (for example, replacing an enclosed garage with a carport), the City's residential parking standards also apply. Owners should confirm specifics with the Planning Division (626-570-5034) before building.
