In unincorporated Sacramento County, storage sheds under 120 sq ft without electrical or plumbing are generally exempt from building permits. Sheds must meet setback, height, and placement requirements per county zoning standards.
Under the California Building Code as adopted by Sacramento County, detached storage structures under 120 square feet without electrical or plumbing are exempt from building permits. Additional requirements apply: sheds under 9 feet tall can be as close as 3 feet to the property line; sheds between 9 and 12 feet tall must be at least 5 feet from the property line; and sheds over 12 feet require standard setbacks. All sheds must be no more than one story and placed in compliance with zoning setback requirements. The Sacramento County Planning and Environmental Review Department provides specific guidance on accessory structure placement in their Residential Accessory Structures handout. Sheds with any electrical, plumbing, or mechanical systems require building permits regardless of size. Pre-fabricated sheds must still comply with setback and placement requirements. Permit applications are submitted through the Sacramento County Building Permits and Inspection Division.
Unpermitted sheds over 120 sq ft or with unpermitted utilities are building code violations. Setback violations may require relocation or removal of the structure. The county may require retroactive permits with additional fees for non-compliant structures.
