Shed permit rules in Rocklin, CA — also referred to as storage shed, backyard shed, or accessory building regulations — set size limits, setbacks, and when a building permit is required.
Under California Building Code §105.2 (adopted by Placer County Code Chapter 15) and Placer County Code 17.56.020, one-story detached storage sheds, playhouses, and similar accessory structures up to 120 sq ft and 12 feet in height do not require a building permit, but must still meet zoning setbacks. Electrical or plumbing work requires permits.
Placer County adopts the California Building Code in Chapter 15 of the Placer County Code. CBC §105.2 (Work Exempt from Permit) exempts one-story detached accessory buildings used as tool/storage sheds and similar uses that do not exceed 120 sq ft in floor area, provided the structure also meets Placer County Zoning Ordinance height (12 ft max measured under the Zoning Ordinance) and setback requirements. If the shed contains electrical wiring or plumbing, separate electrical and/or plumbing permits are required. Sheds over 120 sq ft, or with utilities, require a full building permit and must comply with the CBC, including wildland-urban interface provisions in Chapter 7A if the site is in a designated FHSZ. Setbacks for accessory structures vary by zone district under PCC 17.56.020 — contact Placer County Planning Services for the specific setback for your parcel.
Building a shed that exceeds the 120 sq ft exemption or includes utilities without a permit is a code violation enforced by Placer County Building Services and Code Compliance. Sheds in setbacks or that exceed allowed lot coverage are zoning violations.
