San Jose Zoning System
The San Jose zoning system includes 32 total zone classifications: 6 residential zones (R-1-6, R-1-8, R-2, R-3, R-M, and others) and 5 commercial zones (CG, CN, CP, CO, and others), as well as 4 mixed-use zones (MXP, MXPD, DC) and 4 industrial zones (LI, HI, IP). San Jose uses Municipal Code Title 20 for zoning regulation. As the largest city in the Bay Area and Silicon Valley's urban core, San Jose covers 177 square miles with a diverse mix of residential, commercial, and industrial uses. Residential zones range from low-density single-family (R-1-6 requiring 6,000 sqft lots) to high-density multi-family (R-M). The city has focused growth around the Downtown area, BART/VTA transit corridors, and Urban Villages — mixed-use nodes identified in the General Plan as areas for infill and intensification. The BART Silicon Valley extension (Berryessa station opened 2020, Downtown extension planned) is reshaping zoning near stations. The city maintains an interactive zoning map for property lookup.

Can I build an ADU in my backyard in San Jose?
Yes. California state law requires San Jose to permit ADUs by-right on all residential lots. You can build a detached ADU up to 1,200 sqft, or a Junior ADU (JADU) up to 500 sqft within your existing home. No owner-occupancy requirement applies. San Jose is one of the most ADU-active cities in California due to its housing shortage. Permits are processed ministerially within 60 days.
What are San Jose's short-term rental rules?
San Jose requires short-term rental registration ($200/year) for all rentals under 30 days. Your property must be your primary residence. Transient Occupancy Tax (10%) applies to all short-term rental income. Register with San Jose Finance Department before listing on any platform. Airbnb collects and remits TOT on behalf of qualifying hosts.
What zoning is needed for a single-family home in San Jose?
Most single-family homes in San Jose are in R-1-6 (6,000 sqft minimum lot) or R-1-8 (8,000 sqft minimum lot) zones. These zones allow one primary dwelling plus ADUs per state law. Front setback is 20 ft, side yards 5 ft, and rear yard 20 ft. Building height is limited to 30 ft (2 stories). Check your specific zone at the San Jose GIS Portal: gisportal.sanjoseca.gov.
Do I need a permit to run a business from my home in San Jose?
Yes. A Home Occupation Permit ($200) is required for any business operated from a San Jose residence. Restrictions include: no clients on-site, no non-resident employees, no exterior signs. Business use must be incidental to residential use. Silicon Valley's startup culture makes home occupation permits very common in San Jose.
Are solar panels required on new homes in San Jose?
Yes. California's Title 24 Energy Code requires solar PV on all new low-rise residential construction. San Jose has one of the highest solar adoption rates in the US. PG&E net metering is available under NEM 3.0. SolarAPP+ provides expedited permits for standard residential systems. San Jose's 300+ sunny days per year make solar highly cost-effective.
What are San Jose's ADU setback requirements?
New detached ADUs in San Jose require 4-foot side and rear setbacks per California state law (Gov Code 65852.2). No setback is required for an ADU that replaces an existing structure in the same footprint (e.g., garage conversion). Front setbacks follow the applicable zone standards — typically 20 ft for R-1 zones. No minimum ADU lot size requirement.
