Shed Installation Permits in Pomona

Local Rule

City of Pomona Development Services Department, Building Safety Division; California Residential Code Section R105.2 (Pomona-adopted)

Pomona administers building permits under the statewide California Building Code, which exempts a one-story detached accessory structure used as a tool or storage shed from a building permit when the floor area does not exceed 120 square feet and the structure has no electrical, plumbing, or mechanical systems; prefabricated or site-built sheds over 120 square feet require a permit. The city adopted a comprehensive update to the Pomona Zoning and Development Code effective July 31, 2024. Many Pomona neighborhoods have older housing stock and nonconforming lots, which can complicate setback compliance for accessory structures.

How This Compares to Los Angeles County

Pomona's own rule is shown above (No permit under 120 sqft). Here is the separate rule that applies at the county level, for context:

Los Angeles County / local code

California's building code lowers the shed exemption to 120 square feet (a 10x12 shed), below the national 200, with a 12-foot height cap. Anything larger, taller, on a permanent slab, or with electrical or plumbing needs a permit. In Los Angeles County the shed must also meet zoning setbacks (commonly 5 feet from side and rear lines) and, in fire-hazard zones, ignition-resistant requirements.
