San Jose Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

San José’s zoning is codified as Title 20 of the San José Municipal Code (the San José Zoning Code) and organizes citywide land‑use rules, district tables, and permit rules for development across distinct chapters and overlays. The code establishes the city’s basic zoning districts (residential, commercial, industrial, urban‑village/mixed‑use, downtown, pedestrian‑oriented, and planned development), citywide standards (setbacks, height, FAR/density, parking), and procedural chapters that govern discretionary and ministerial review. For navigation, the Zoning Code points readers to chapter‑level rules (e.g., residential rules in Chapter 20.30, parking in Chapter 20.90) and to the Specific Plans process in Title 18 for area plans. See the formal Title citation in § 20.10.010.

How San Jose's code is organized

• Title and purpose: The Zoning Code is explicitly the San José Zoning Code and states its purposes (public health, safety, land‑use consistency with the General Plan) in § 20.10.010 and § 20.10.020.

• Table of chapters: The code groups regulation by topic (e.g., Chapter 20.30 — Residential Zoning Districts, 20.40 — Commercial, 20.50 — Industrial, 20.55 — Urban Village & Mixed Use, 20.65 — Overlay Districts, 20.70 — Downtown, 20.90 — Parking, Loading & TDM, 20.100 — Administration & Permits, 20.195 — Ministerial Approvals) and Section/Chapter headings are the primary way to find rules. The title itself lists these chapter headings and their functions.

• Specific plans and area plans live in Title 18 under the Specific Plans chapter (see § 18.20.010 through § 18.20.080) and are implemented alongside Title 20 standards where adopted.

• Where the Zoning Code defers to objective design rules, it instructs users to consult the Citywide Design Standards and Guidelines; these are applied expressly to the Urban Village/Mixed Use districts (see § 20.55.030).

Zoning district families

San José organizes districts into families; key names and locations in the code:

• General provisions / districts established — the authority establishing the districts is in § 20.10.060; Chapter 20.10 contains the general provisions and map/district rules.

• Residential districts — rules, allowed uses and specific residential development standards live in Chapter 20.30 (examples: single‑family and multiple‑family regulations, accessory building rules, fence, setback and height measurement rules). See, for example, setback rules and SB 9 implementation in § 20.30.010 and related provisions.

• Commercial / Public‑Quasi‑Public — Chapter 20.40 holds the commercial district regulations and development standards (use tables and performance standards are located there).

• Industrial districts — Chapter 20.50 contains LI/HI/IP performance standards, setbacks, and use rules.

• Urban Village & Mixed‑Use districts — the city’s higher‑intensity districts are the UVC, UV, MUC, MUN, UR, and TR districts and are set out in Chapter 20.55; each district’s purpose and whether residential is permitted is described in § 20.55.010 and related sections (the chapter also prescribes how FAR vs. du/acre are applied).

  • In those districts the code points to the Citywide Design Standards and to adopted Urban Village Plans; where plan standards exist they prevail over default chapter provisions (§ 20.55.020–.030).

• Downtown zoning districts — the downtown primary commercial and transition districts (DC, DC‑NT1, etc.) and their ground‑floor active‑use overlay (AUA) are in Chapter 20.70 and grant special standards for ground floor uses and downtown parking/bicycle/loading.

• Pedestrian oriented / Main Street — in Chapter 20.75 the code defines pedestrian‑oriented districts (MS, MS‑C, etc.) and building frontage/placement rules.

• Planned Development (PD) — PD districts are authorized in § 20.10.070 and Chapter 20.60 contains PD implementation rules.

Citywide development standards (high‑level)

San José provides a mix of district‑specific tables and citywide rules; the code sets where to find the controlling numeric standards.

• Floor area ratio (FAR) and density: For Urban Village and Mixed Use districts the code specifies whether a district uses FAR or dwelling units per acre (DU/AC) and directs users to Table 20‑136 and related text (see § 20.55.040 for applying FAR vs. DU/AC; maximums and minimums for UVC, UV, MUC, MUN, UR, TR are listed there).

• Setbacks and projections: Citywide setback rules for residential and mixed‑use lots (including allowed projections, front/side/rear rules, and when rear setbacks may be zero adjacent to commercial) appear in § 20.55.101 and related residential chapters (see § 20.30.400–.440 for residential projections and front setback limitations). Those sections also explain allowable small projections, mechanical equipment placement, and alley assumptions.

• Height and measurement: The zoning code explains basic height limits and measurement conventions (e.g., measurement of height, maximum height exceptions, and rooftop exceptions) in Chapter 20.30 for residential and in Chapter 20.85 for area‑specific height rules; see § 20.30.610 and § 20.85.010 for how heights are measured and where exceptions may be established.

• Lot coverage / open space: Common and private open space requirements for residential/mixed‑use developments in UV/MUC/UR/TR districts are set in § 20.55.102 (minimum usable open space standards).

• Parking, loading and TDM: Off‑street parking, loading, and Transportation Demand Management standards are in Chapter 20.90 (general rules, two‑wheeled vehicle standards, and Downtown bicycle standards appear within Chapters 20.90 and 20.70). For example, the general purpose and detailed bicycle parking rules are organized under § 20.90.300 et seq.; downtown bicycle and loading standards are in § 20.70.485 and § 20.70.410.

• Design standards: Where chapter development rules are not sufficiently prescriptive (notably in Urban Village/Mixed Use districts), the code requires use of the Citywide Design Standards and Guidelines; see § 20.55.030.

Specific plans & overlays

• Specific plans: The Specific Plans process (area‑level, implementing General Plan policies and creating custom land‑use/implementation standards) is codified in Title 18, Chapter 18.20; the code explains plan elements, initiation, hearings, and relations to the General Plan (§ 18.20.010–.080). Specific plans, once adopted, control development within their boundaries and can supply specialized design and implementation rules.

• Overlay districts: Overlays (Chapter 20.65) layer additional rules onto base zoning. San José identifies overlays such as the AHO (Affordable Housing Overlay), MIHO (Mixed‑Income Housing Overlay), HERO (Housing Element Residential Overlay), TERO (Transit Employment Residential Overlay), and neighborhood business overlays (e.g., Japantown, Willow Glen). Each overlay part contains applicability, development standards, and any affordable housing or inclusionary conditions (see § 20.65.010 and the individual overlay sections such as § 20.65.050 for TERO and § 20.65.070–.110 for AHO).

Building permits & review (permit paths)

• Permit categories: The Zoning Code separates discretionary land‑use permits (conditional use permits, special use permits, planned development permits, site development permits) from ministerial approvals and administrative permits. Chapter 20.100 is the primary administrative and permit chapter (see § 20.100.010 for the permits overview and § 20.100.620–.630 for site development permit procedures and findings).

• Site development permits & design review: Projects requiring review under site development permits must be noticed and fit findings about consistency with the General Plan, the Zoning Code, and neighborhood compatibility; the director/commission/council must make specific findings in § 20.100.630 before granting such permits. These findings explicitly require that design, landscaping, traffic/pedestrian access, and environmental impacts be addressed.
  (First mention: San Jose Design Review) /us/california/san-jose/design-review

• Ministerial / streamlined paths: The code contains a Chapter 20.195 for local ministerial approvals (streamlined infill, ministerial approvals in overlays, emergency shelter ministerial approvals) with objective standards for eligible projects; see § 20.195.070–.090. Ministerial paths require meeting objective site, design and construction standards in Titles 17, 19 and 20 before approval.

• Building permits & Title 24 / local building code: While zoning establishes land‑use and site standards, building permits and construction code compliance are processed under Title 17 (Building and Construction) and the California Building Standards Code (Title 24). The Zoning Code cross‑references Title 17 as part of the ministerial standards (see § 20.195.080 referencing Titles 17 and 19). For the state construction codes, consult the City's building division materials and the California Building Standards Code.
  (First mention: California Building Standards Code) /us/california/building-codes

• Appeals and variances: Appeals procedures (to director, Planning Commission and City Council) and administrative variance-type mechanisms are in Chapter 20.100 (appeal sections § 20.100.220–.280) and Development Variances / Exceptions procedures (e.g., development variances in § 20.100.1310–.1330). See also the Planned Development and PD‑exception provisions in Chapter 20.60.

State housing law in San Jose

San José’s Zoning Code incorporates and implements several California housing laws through local sections and cross‑references. Below are the main intersections.

Accessory Dwelling Units (ADUs) & Junior ADUs

• Local ADU rules are in Chapter 20.80 (see § 20.80.181 et seq. for purpose/applicability and § 20.80.183–.185 for permit and condominium ADU rules). The code includes streamlined approval language and amnesty provisions consistent with state ADU law. For the state statutory baseline, consult California ADU law and the state building standards.

Senate Bill 9 (Lot splits / two‑unit ministerial approvals)

• San José includes explicit SB 9 implementation provisions under the residential chapter; see § 20.30.010 for SB 9 implementation and § 20.30.800–.840 for urban lot split and additional requirements/waivers. These sections set local objective standards and cross‑reference ministerial and streamlined review where applicable.
  (First mention: California housing laws) /us/california/housing-laws

Density bonus / affordable housing incentives

• The city’s local density bonus and incentives are codified in Chapter 20.190 (Affordable Housing Density Bonuses and Incentives). Developers seeking state density bonus rights must consult both state density bonus law and the local Chapter 20.190 requirements and incentives.

Local tenant protections and rental rules

• Title 20 includes tenant/buyer protection provisions and conversion/relocation requirements under Chapter 20.170 (tenant/buyer protections, notice of intention to convert, relocation assistance, unjust eviction rules). The Zoning Code excerpts retrieved discuss protections tied to condominium conversions and tenant notice/relocation rather than a broad apartment rent‑control ordinance; the code excerpts do not present a comprehensive citywide rent‑control chapter in Title 20. Verify with the City Attorney or Housing Department for current rent regulation programs. See § 20.170.420–.430 for conversion and relocation protections.

Practical orientation and tips

• If you’re looking up a site: start with the parcel’s zoning on the official Zoning Map, then read the district chapter (e.g., 20.30 for residential or 20.55 if in an Urban Village) and the applicable overlay chapter (Chapter 20.65) for additional rules; both the district and overlay controls may be binding (see § 20.10.060 and § 20.65.010).

• For numeric standards: refer to the district‑specific tables (Table 20‑40, Table 20‑136, Table 20‑144, etc.) described in the district chapters and in Chapter 20.55 for Urban Village FAR/du/acre guidance (§ 20.55.040).

• For design review and discretionary approvals: anticipate site development permit findings and public hearing notice timelines under § 20.100.620–.630 and the appeal rules in § 20.100.220–.280.

• For fast, ministerial housing approvals: check Chapter 20.195 for whether your project qualifies for local streamlined/ministerial approval (and ensure compliance with Titles 17/19/20 objective standards referenced in § 20.195.080).

Information Gaps / Verify with the city

• The file excerpts provided cover the Zoning Code table of contents, many chapter headings, and numerous specific sections, but they are excerpts of the municipal code. For a full, current numeric table (exact setback feet, FAR numbers for every district, and the complete text of Tables 20‑136 / 20‑140), consult the official San José Municipal Code website and the current Zoning Map. Where I cite chapter headings and specific sections above, consult the full ordinance text for complete numeric figures and cross‑references. (If you want, I can pull specific table entries or the full page text next.)
