San Jose — Design Review

Last reviewed: July 2, 2026

Overview

San José implements design review primarily through its development-permit framework in Title 20 (Zoning). Most new construction and many exterior changes require a site development permit or a project-specific development permit; single-family proposals use a focused single-family house permit process. The code ties aesthetic and site-compatibility decisions to specific findings (compatibility, landscaping, access, neighborhood character) that decision makers must make before approval. See the city's zoning rules for how design review interacts with zoning, overlays, historic-review, and development standards. § 20.100.610, § 20.100.630

Note on links used below: when the text first discusses related topics I link to the city pages for zoning, development standards, parking, overlays, historic preservation, ADUs, and the California building code so applicants can find connected guidance: the city's Zoning overview, Development Standards, Parking, Overlay Districts, Historic Preservation, ADUs, and the California Building Standards Code.

How San José organizes "design review" in Title 20 (what the code calls it)

• The primary vehicle for design review is the site development permit and related development permits (planned development, special use permits, and single‑family house permits). Projects that trigger a development permit must meet the findings in § 20.100.630 before the Director, Planning Commission, or City Council may approve the permit. § 20.100.610, § 20.100.630
• Single‑family houses in residential zones have a dedicated permit path and findings under the Single‑Family House Permit rules; this process applies in R-1, R-2, and RM districts. § 20.100.1000–§ 20.100.1005
• Downtown and special districts have their own permit and design-guideline chapters (for example, downtown design guidelines and permit procedures). See the Downtown chapter and its design guidelines. § 20.70.500–20.70.600, § 20.70.700
• Overlay and area‑specific rules may add or change design review requirements; overlay districts are defined at § 20.65.010 and then further in their respective overlay sections. § 20.65.010
• Historic resources require parallel review under the Historic Preservation Chapter; Historic Preservation (HP) permits and comments from the Historic Landmarks Commission may be required and are coordinated with Title 20 reviews. See Chapter 13.48 and its cross‑references to Title 20. § 13.48.210–13.48.240

District-by-district breakdown (where design review standards and expectations differ)

Notes: Where the municipal code defines a district purpose or process I cite the controlling section. Specific numeric dimensional controls (exact setbacks, heights, FAR) are in each district's development standards or in tables referenced in Title 20; if a precise numeric standard could not be found in the retrieved snippets for a district, I mark that as Not found in retrieved materials and advise verification with staff.

Residential districts — R-1, R-2, RM

• Purpose: The Single‑Family House Permit purpose (to maintain neighborhood character and regulate aesthetics and site functionality) is set out in § 20.100.1000. The single‑family permit rules apply to R-1, R-2, and RM. § 20.100.1000, § 20.100.1005
• Typical permitted uses: Single‑family dwellings (R-1) and multi‑unit residential uses per the residential district tables (see applicable use tables in Title 20). Not found in retrieved materials for full permitted use lists in the snippets; verify with Table 20‑140/underlying district tables. Verify with the jurisdiction.
• Key dimensional standards: Not found in retrieved materials for district‑specific numeric setbacks/height/FAR in these snippets — those standards are in each district's development standards tables elsewhere in Title 20. Verify with the jurisdiction and in Table 20‑xxx for the specific zoning parcel.
• Where it applies: Citywide residential neighborhoods zoned R-1, R-2, RM. Single‑family permit requirements and adjustments are described in Part 9 of Chapter 20.100. § 20.100.1000–§ 20.100.1030

Downtown — DC, DC‑NT1

• Purpose: Downtown districts have special pedestrian- and street‑oriented design expectations and their own permit rules. See § 20.70.010–20.70.020 for downtown applicability and overlays; downtown permit issuance references Chapter 20.100 procedures. § 20.70.010–20.70.020, § 20.70.600
• Typical permitted uses: Uses are enumerated in downtown use tables referenced in Title 20 (Table 20‑140 and related sections). See downtown uses chapter for allowed retail, office, residential and mixed‑use rules. Not found in retrieved materials for a full list; verify with Table 20‑140. Verify with the jurisdiction.
• Key dimensional standards: Downtown height and setback rules are in the downtown chapter (e.g., § 20.70.200 for height), and downtown design guidelines are codified in § 20.70.500. § 20.70.200, § 20.70.500
• Where it applies: Areas designated as downtown zoning districts and any Downtown overlays (see § 20.70). § 20.70.020

Mixed‑Use / Urban Village — UV, MUC, UR, TR

• Purpose: Encourage mixed residential/commercial forms with specific open space and compatibility standards. See the common/private open space requirements that apply to these districts. § 20.55.102
• Typical permitted uses: Mixed residential and commercial uses per the mixed‑use district use tables and project standards (refer to the Urban Village and Mixed Use chapters). Not found in retrieved materials for a complete list; verify with the parcel's zoning table.
• Key dimensional standards: Open-space minimums and unit thresholds are in § 20.55.102 (common/private open space formulas for UV, MUC, UR, TR); other dimensional limits are in the district tables. § 20.55.102
• Where it applies: Sites zoned UV, MUC, UR, TR, and within identified urban-village plan areas. § 20.55.102

Commercial districts — CP, CN, CG

• Purpose: Commercial zoning and performance standards are established in Chapter 20.40. Permit review and temporary structure exceptions are referenced in several provisions (e.g., temporary sales structures allowances). See § 20.40.* for rules. § 20.40.100 et seq.
• Typical permitted uses: Retail, offices, restaurants and other commercially‑oriented uses as listed in each district's use table. Not found in retrieved materials for a complete list; verify with the municipal code use tables.
• Key dimensional standards: Setback rules generally follow the underlying zoning district and are referenced in the district chapters (setback language appears in the code index). Not found in retrieved materials for specific numeric standards for CP/CN/CG in the snippets — verify with the code's development standards tables.
• Where it applies: Neighborhood and regional commercial strips citywide; downtown commercial uses are governed by the Downtown chapter when in that district. § 20.40., § 20.70.

Industrial districts — IP, LI, HI

• Purpose: Industrial districts and related performance standards are in Chapter 20.50. Certain exceptions to front/side/rear setbacks exist for LI and HI. § 20.50.010, § 20.50.200–20.50.240
• Typical permitted uses: Industrial, light manufacturing, warehousing, and some support commercial uses per Title 20 tables. Not found in retrieved materials for a complete list; verify with the relevant use table.
• Key dimensional standards: Some setback exceptions are spelled out (e.g., front setback exceptions for LI/HI). See § 20.50.200 and § 20.50.230. § 20.50.200–20.50.230
• Where it applies: Properties zoned IP, LI, HI citywide. § 20.50.010

Planned districts / Special projects — Downtown West Planned Development

• Purpose & special rules: The Downtown West Planned Development Zoning District has its own adopted General Development Plan and supersedes some Title 20 provisions where conflicts occur. See § 20.70.700 and the ordinance creating Downtown West standards. § 20.70.700
• Where it applies: The Downtown West planned area only; development approvals follow the adopted Downtown West ordinance rather than generic Title 20 provisions where specified. § 20.70.700

Overlay districts

• Purpose & application: Overlays add or modify rules and are codified in Chapter 20.65. Overlay regulations are applied in addition to the base zoning and can materially change design-review expectations. § 20.65.010–20.65.030

Practical guidance / synthesis (plain‑English direction for designers and applicants)

• If your project is more than a single‑family house, expect a site development permit process that focuses on visual and functional compatibility: the city evaluates consistency with the General Plan and neighborhood, building orientation and elevations, landscaping and screening, and traffic/pedestrian access. See § 20.100.610 and § 20.100.630. § 20.100.610, § 20.100.630
• If the property is in downtown, an urban village, or an overlay (for example UV, MUC, or a Neighborhood Business Overlay), expect extra, district‑specific design requirements and possibly different reviewers or findings (see § 20.70 and § 20.65). § 20.70.500–20.70.600, § 20.65.010
• If the site is a designated historic resource or in a historic district, the Historic Preservation chapter steps in and may require an HP permit in addition to Title 20 permits; the Historic Landmarks Commission's advisory comments are part of the record and may be required prior to action. § 13.48.210–13.48.240
• Early referrals: the Director may set hearings and forward applications to commissions (including Historic Landmarks or Planning Commission) for comment or decision depending on the permit type and Table 20‑260 hearing authorities. See the action-by-director rules. § 20.100.620, Table 20‑260 (referenced)
• Technical or site‑specific standards like parking, setbacks, loading and bike parking are enforced through other Title 20 chapters (for parking see the city's Parking page and Chapter 20.90). Chapter 20.90 and related district setback sections apply. § 20.90.*

Checklist

• Confirm which permit type applies: Site Development Permit, Single‑Family House Permit, Planned Development, or HP permit (Historic). § 20.100.610; § 20.100.1000–1005; Chapter 13.48
• Meet the approval findings: consistency with General Plan/specific plan; conformance with zoning; neighborhood compatibility (orientation, elevations); landscaping, trash/utility screening; traffic/pedestrian access. § 20.100.630
• Prepare architectural elevations, site plan, landscape plan, lighting, materials/colors, utility/trash screening, and parking/loading plans consistent with district standards (Downtown projects must include downtown design guidelines conformance). § 20.70.500; Chapter 20.90; § 20.55.102
• For projects in overlays or special plans, assemble the overlay-specific standards (Chapter 20.65) and any development agreements. § 20.65.010
• If historic, file HP permit application materials and anticipate coordination with Historic Landmarks Commission; allow the 45‑day advisory review where applicable. § 13.48.210–13.48.240
• Confirm parking requirements and TDM (transportation demand management) obligations under Chapter 20.90. § 20.90.*
• Check Table 20‑260 and the Director’s hearing/appeal rules to understand who makes the decision and the appeal path. § 20.100.620; § 20.100.660

Risks & Ambiguities

Plain‑English Summary

If you're building or changing anything more than a typical single‑family house, San José will usually require a site development permit (or another development permit) that performs the city's design review: staff or a commission checks whether the building's siting, elevations, landscaping, parking, and access fit the General Plan, zoning, neighborhood character, and any overlay or historic rules before a building permit is issued. § 20.100.610; § 20.100.630
