Shed Installation · Imperial County, California
In Imperial County, a Shed Installation under 120 sq ft generally does not require a building permit. At or above 120 sq ft, a permit is required.
The county follows the standard statewide 120-square-foot exemption for a detached tool or storage shed, but the same Division of Building & Safety also administers a distinct, separately defined structure category that has nothing to do with ordinary storage: the county's cannabis ordinance defines a personal-cultivation accessory structure as a fully enclosed and secured building in the rear yard, not visible from a public place, capped at 100 square feet, a size threshold specific to that use and lower than the shed exemption itself. The county is also the lead agency for mobile home park regulation under Title 25 of the California Code of Regulations, so mobile home park installations such as carports, decks, and cabanas go through the same building-permit process as a standard accessory structure rather than a separate mobile-home-specific track. Building permits in Imperial County are handled under the Imperial County Planning & Development Services, Division of building code (IRC California Building ). Local zoning, property-line setbacks, and any electrical or plumbing work can still require separate approval, so confirm the details with Imperial County Development Services.
