City of Folsom

Building permits are required for work regulated by the adopted California building codes and Folsom Municipal Code. Construction cannot start until the permit is issued.

• Exempt Exempt work generally follows the work-exempt provisions in the California Building Code and California Residential Code adopted by Folsom
• Exempt Common examples include small detached accessory structures up to 120 square feet
• Exempt Certain fences not over 7 feet high
• Exempt Certain retaining walls not over 4 feet measured from the bottom of the footing
• Exempt Platforms and walks not more than 30 inches above grade and not over a qualifying area
• Exempt Painting, papering, cabinet work, and similar finish work
• Exempt Prefabricated pools meeting the code small-size threshold
• Exempt Playground equipment for one- and two-family dwellings

Note: Exemption from a building permit does not waive compliance with zoning, design review, historic district rules, utility clearances, or other agency approvals. In Historic Folsom, separate design review rules may still apply even where a building permit is not required.

Building code

As of January 1, 2026, permit applications submitted on or after that date must comply with the 2025 California Building Standards Code. Applications submitted before January 1, 2026 may remain under the 2022 code cycle so long as the application or permit does not expire.

Permit validity

Folsom states permit applications expire 180 days after filing if not issued. Issued permits expire 12 months after issuance if work has not commenced to the Building Official satisfaction, or if more than 180 calendar days pass between approved required inspections after that initial period. Folsom also states that, per the Municipal Code, building permits expire two years after issuance. A one-time 180-day written extension may be granted for justifiable cause if requested before expiration.

Owner-builder

If the property owner is personally performing the work, Folsom requires an Owner-Builder Verification before permit issuance. The owner-builder becomes the responsible party of record and may incur employer obligations if hiring unlicensed workers.

Contractor requirements

Folsom owner-builder materials state contractors are required by law to be licensed and bonded in California and must place their license number on permit applications.
