Fresno, California Zoning & Land Use Guide
Key Zoning Facts
Fresno Zoning Overview
Fresno is the fifth-largest city in California and the largest city in the San Joaquin Valley. The city's zoning and land use regulations are administered by the Development & Resource Management Department under the Fresno Municipal Code.
Residential Zoning
Fresno's residential zoning system uses a tiered RS (Residential Single-Family) framework. RS-1 covers estate lots of 10,000 sq ft or more, RS-3 applies to standard suburban lots of 6,000 sq ft, and RS-5 supports smaller urban lots of 5,000 sq ft. The RM-1 zone allows multi-family housing including apartments and townhomes.
ADU Development
Fresno supports ADU construction under California's statewide framework. The city has worked to streamline the ADU permit process, and property owners on residentially zoned lots can build detached ADUs up to 1,200 square feet with ministerial approval within 60 days. Fresno's relatively affordable land and lower construction costs make it an attractive market for ADU development.
Agricultural Interface
As a major agricultural center, Fresno has unique land use considerations at the urban-agricultural boundary. Buffer zones and transition areas between residential development and farming operations help manage compatibility. The city's General Plan addresses long-term urban growth boundaries and agricultural preservation.
Downtown Revitalization
The Downtown Neighborhoods Specific Plan introduces form-based code standards for central Fresno, encouraging mixed-use development, pedestrian-friendly streetscapes, and higher-density infill housing near the city core.
