Fremont, California Zoning & Land Use Guide
Key Zoning Facts
Fremont is the fourth-largest city in the San Francisco Bay Area, located in southern Alameda County with a population of approximately 230,504 (2020 Census). The city's zoning and land use framework is administered by the Community Development Department's Planning Division under Fremont Municipal Code Title 18.
Residential Zoning Districts
Fremont's residential zoning uses a detailed system with lot-size-based designations:
- R-1 Single-Family Districts range from R-1-6 (6,000 sq ft minimum lots) to R-1-40 (40,000 sq ft minimum lots, typically in hillside areas). The most common are R-1-6 and R-1-8.
- R-2 Duplex Residential allows two-family dwellings on 8,000 sq ft minimum lots.
- R-3 Multi-Family Districts range from R-3-10 (up to 10 units/acre) to R-3-30 (up to 29.9 units/acre), with increasing height and coverage allowances at higher densities.
- R-G Garden Residential Districts (R-G-15 through R-G-40) provide for attached housing types like townhomes and rowhouses.
Special Planning Areas
Fremont has several specialized zoning districts including the Warm Springs Innovation District near the BART station, City Center Districts (CC-TN, CC-UO, CC-UN), and Downtown Districts (D-CA, D-MD, D-E, D-CC). The Transit-Oriented Development (TOD) overlay applies additional standards near BART stations.
ADU Development
Fremont permits ADU construction on all residentially zoned lots per California state law and local ordinance (Fremont Municipal Code Section 18.190.005, Ordinance 06-2023). Detached ADUs up to 1,200 square feet are allowed with 4-foot rear and side setbacks and a 16-foot height limit. The city offers a preapproved plans program with expedited 7-business-day review and a flat $1,000 plan review fee. No additional parking is required. JADUs up to 500 square feet are also permitted within existing structures.
