Before You Build in Florin, CA: Permit & Rule Checklist (2026)

Sacramento County Zoning Code §5.2.5 limits solid front-yard fences in residential zones to 3 feet, semi-open picket fencing to 4 feet, open chain link to 4 feet, and open wrought iron to 7 feet. Side-street, interior side, and rear fences may be up to 7 feet.

Retaining walls over 4 feet (measured from bottom of footing to top of wall) require a building permit per the California Residential Code adopted via SCC Title 16. Any retaining wall supporting a surcharge (additional structural load like a driveway, building, or pool) requires a permit regardless of height.

Fences up to 7 feet in interior side and rear yards generally do not need a building permit in unincorporated Sacramento County. Front-yard fences must comply with §5.2.5 height limits; retaining walls over 4 feet (or any height supporting a surcharge) require a permit.

Sacramento County Zoning Code §5.2.5.A.2 requires perimeter fences around private pools not otherwise restricted from unauthorized public access, built to California Building Code §3109.4.4.3. The standard CBC barrier is at least 60 inches tall with self-closing, self-latching gates and openings no greater than 4 inches.

New swimming pools in Florin require a building permit from Sacramento County Building. The permit covers pool structure, electrical, plumbing, and the California Building Code §3109 perimeter barrier. Construction must comply with Zoning Code §5.2.5 walls and fences and the Pool Safety Act (SB 442).

California Pool Safety Act (Health and Safety Code §115920 et seq., SB 442) requires every newly constructed or remodeled swimming pool at a private single-family home to include at least two of seven listed drowning-prevention safety features.

Florin ADUs are regulated by Sacramento County Zoning Code §5.4.5 (Residential Accessory Structures and ADUs) and the state ADU statute (Gov. Code §65852.2). The County allows one ADU plus one JADU on a single-family lot, with detached ADUs typically capped at 850 sq ft (1 bedroom) or 1,000 sq ft (2+ bedrooms).

Converting an existing garage into a habitable space (bedroom, ADU, JADU) requires a building permit and must meet Zoning Code §5.4.5 ADU standards or Building Code habitability standards. The converted space typically counts toward residential floor area and lot coverage limits.

Detached accessory structures up to 120 sq ft are typically exempt from a building permit in Sacramento County (per CBC §105.2). Larger structures require permits and must comply with Zoning Code §5.4.5 setbacks and height limits.

A foundation-built tiny home meeting the California Residential Code can qualify as an ADU under Sacramento County Zoning Code §5.4.5 - up to 850 sq ft (1BR) or 1,000 sq ft (2BR+). Tiny homes on wheels (THOWs) are recreational vehicles and cannot be occupied as a permanent residence on a residential Florin lot.

Open agricultural and yard-waste burning in unincorporated Sacramento County requires a Sacramento Metro AQMD permit and is only allowed on declared 'permissive burn days.' Residential yard-waste burning is generally prohibited in the urban Florin area.

Open burning is regulated by Sacramento Metro Air Quality Management District (SMAQMD) and the Sacramento County Fire Code. Residential recreational fires in approved devices (gas patio heaters, propane fire pits, and small wood-fueled chimineas) are generally allowed except on Spare-the-Air (no-burn) days called by SMAQMD November 1 - February 28.

Removal of any heritage California oak (60+ inches girth measured 4.5 ft above ground) or designated landmark tree on private property in unincorporated Sacramento County requires a Tree Permit under SCC Chapter 19.04 and Chapter 19.12.

Routine trimming of trees in Florin generally does not require a permit unless the tree is a heritage California oak or landmark tree under Chapter 19.04/19.12. Even for protected trees, light pruning (less than 10-25% of canopy) typically falls under the exempt maintenance category.

Florin water service is provided by the Sacramento County Water Agency (SCWA) Zone 40 / Florin Resource Conservation District and California Water Service. Year-round watering restrictions limit landscape irrigation to assigned days and prohibit watering between 10 a.m. and 7 p.m.
