How Permitting Works in Folsom, California

Building an ADU in Folsom follows clear guidelines set by California state law and local city ordinances. We handle all paperwork directly with the City of Folsom Community Development Department located at 50 Natoma Street, Folsom, CA 95630.

Here are the key zoning rules you should know:

Unit Size Limits: You can build a detached ADU up to 1,200 square feet on single-family lots. Attached units can be built up to 50% of your main house size.
Property Setbacks: State law requires only 4-foot side and rear setbacks for new detached units. Existing garage conversions do not require any new setbacks.
Building Heights: Detached units can reach 16 to 18 feet in height, while attached units can reach up to 25 feet conforming to main house limits.
Local Utilities: We connect your unit to SMUD for electricity and City of Folsom Environmental Utilities for water and sewer. This ensures safe water pressure and reliable electrical service.
HOA Protections: If you live in an HOA community, California law (AB 670 and AB 3182) prevents your HOA from banning accessory dwelling units.
Review Timelines: City plan reviewers are required by state law to process complete ADU permit applications within 60 days.
