San Jose Zoning Overview

San Jose's zoning is governed by Title 20 of the San Jose Municipal Code, administered by the Planning, Building and Code Enforcement Department. As the largest city in the South Bay and the heart of Silicon Valley, San Jose's zoning framework balances residential neighborhoods with commercial, industrial, and mixed-use areas.

Zoning Framework

The city uses standard residential zone designations: R-1 (single-family), R-2 (two-family), and R-M (multiple residence). The R-1 zones include numeric suffixes indicating minimum lot size (e.g., R-1-8 requires 8,000 sq ft minimum lots). San Jose also has planned development (PD) zones that apply custom standards to specific sites.

Urban Villages

A key component of San Jose's growth strategy is the Urban Village plan, which designates specific areas for higher-density, mixed-use development near transit. These areas have their own development standards and are central to the city's Envision San Jose 2040 General Plan.

ADU Policies

San Jose encourages ADU construction and has aligned its local ordinance with California state law. The city offers streamlined ministerial review for qualifying ADU projects, with a 60-day review timeline. ADUs are permitted on all residentially zoned lots with no additional parking requirement.
