San Jose — Development Standards

Last reviewed: July 2, 2026

Overview

This page summarizes the San José zoning Development Standards most relevant to site planning: setbacks, height, lot coverage / floor area ratio (FAR), and density as they appear in Title 20 of the San José Municipal Code. It focuses on the actual local districts used by the City (residential variants, mixed‑use districts, pedestrian/Main Street, open space/agriculture, and selected overlays) and points you to the controlling code sections for each rule so you can verify parcel‑specific requirements. For background on zoning policy and citywide rules see the San José zoning overview and related pages on setbacks and development standards and parking, and for project review triggers see design review.

District‑by‑district development standards

Notes on citations and code references below:

• Whenever I reference a controlling ordinance paragraph I give the code citation with the § glyph (for example § 20.30.200) and include the document citation from the retrieved Title 20 material so you can find the exact table or rule.

R‑1 (One‑Family Residence districts — e.g., R‑1‑8, R‑1‑5, R‑1‑2, R‑1‑1, R‑1‑RR)

Purpose & typical uses: single‑family dwellings and accessory residential uses.
Key dimensional standards (selected examples from Table 20‑60): front setbacks and other minimums vary by R‑1 subtype — for example R‑1‑8: front setback 20 ft, interior side setback 5 ft, corner side 12.5 ft, rear 20 ft, maximum height 35 ft, maximum stories 2.5 as measured in § 20.30.200 . Where exceptions (e.g., minor one‑story additions) apply see § 20.30.310 .
Where it applies: citywide residential neighborhoods zoned for detached houses. Verify parcel’s R‑1 subtype on the Zoning Map.

Practical guidance: use § 20.30.200 to pull the exact numeric row for your R‑1 subtype; the table differentiates minimum lot area, front/side/rear setbacks, driveway length, and height limits.

R‑2 (Two‑Family Residence)

Purpose & uses: duplexes/two‑unit residential.
Key standards: typical front setback 15 ft, interior side 5 ft, corner side 10 ft, rear 25 ft, max height 35 ft, max stories 2.5 per § 20.30.200 .
Where it applies: multi‑family transition lots and smaller residential parcels.

R‑M (Multi‑Family Residential)

Purpose & uses: medium‑density multi‑family housing.
Key standards: typical front setback 10 ft, interior side 5 ft, corner side 7.5 ft, rear 25 ft, maximum height 45 ft (or alternative heights noted in Chapter 20.85) — see § 20.30.200 and height exceptions rules in § 20.85.040.

Practical guidance: R‑M allows taller buildings than R‑1/R‑2 but check Chapter 20.85 for site‑specific alternative height limits.

R‑MH (Manufactured/Mobilehome Residential)

Purpose & uses: mobilehome park lots; development standards similar to multi‑family in some measures. See § 20.30.200 for numeric standards.

MUN — Mixed Use Neighborhood

Purpose & typical uses: pedestrian‑scaled mixed‑use and residential neighborhoods; two sets of standards exist (Conventional and Alternate for small‑lot developments). See § 20.55.104.
Key dimensional standards (Table 20‑137):

• Conventional: minimum lot area 1,452 sq ft per unit, front setback min 10 ft, FAR 0.25–2.0 for mixed use, maximum 30 du/ac for residential projects. § 20.55.104 .
• Alternate: intended for small‑lot/no‑setback courtyard or private‑street projects; may allow no minimum lot area or no frontage requirement but requires concurrent site/subdivision review. § 20.55.104 .

Practical guidance: if you’re doing small‑lot/townhouse product, the Alternate standards can change setbacks and frontage rules — plan early to file concurrent permits. Overlays (see the Neighborhood Business overlay rules) can further modify MUN standards.

Urban Village and Mixed‑Use classes: UV, UR, TR, MUC

Purpose & typical uses: higher‑intensity mixed‑use zones inside Urban Villages and certain commercial/mixed areas. Standards are expressed as FAR ranges and du/acre minimums/maximums. See § 20.55.040 and § 20.55.100 (Table 20‑136).

Representative standards (Table 20‑136 / § 20.55.040):

• UV (Urban Village): maximum FAR up to 10.0; mixed use minimum density 55 du/ac (minimums/max vary by subdistrict) § 20.55.040 .
• UR: minimum 1.0 FAR, maximum 4.0 FAR, mixed‑use minimum 30 du/ac § 20.55.040 .
• TR and MUC have their own FAR/du‑ac ranges summarized in § 20.55.040–100; mixed‑use projects must meet both FAR and du/ac standards.

Practical guidance: for mixed‑use projects calculate FAR including both commercial and residential floor area (code explicitly requires combined FAR calculations for mixed use) — see § 20.55.040.B.1–2.

MS‑G / MS‑C (Main Street — pedestrian oriented districts)

Purpose & typical uses: pedestrian retail and mixed ground‑floor uses. Controls emphasize build‑to lines and active frontage. See § 20.75.100–120 and Table 20‑151.
Key standards: front build‑to line 5 ft (Main Street) or 2 ft (minor cross street); front setback max 10 ft; minimum percent of façade on build‑to line 70% on Main Street; side interior setback: none, but a minimum 15 ft setback is required adjacent to residential zoning. § 20.75.110 and Table 20‑151.

Practical guidance: Main Street districts are about street presence rather than large setbacks — expect design review to enforce active ground‑floor frontage and transparent façade requirements; see the citywide design standards and design review.

OS / A (Open Space / Agriculture)

Purpose & uses: open space, agriculture, limited support structures. Key table: Table 20‑40 § 20.20.200.
Representative standards: minimum lot area OS/A 20 acres, setbacks from abutting streets 50 ft, setbacks to abutting residential property 300 ft for OS, maximum height 35 ft or as established in Chapter 20.85, FAR may be limited or none for OS. § 20.20.200

Practical guidance: OS/A parcels are highly constrained by minimum lot area and large setbacks; check overlay maps (Coyote Valley Agriculture Overlay) where different minimums apply.

Selected Overlay: TERO (Transit Employment Residential Overlay)

Purpose & where: targeted in North San José to allow residential or mixed uses near employment/transit corridors. See § 20.65.060.
Key standards in the overlay: minimum lot area for mixed use 6,000 sq ft, 100% residential density 75–250 du/ac, maximum building height up to 270 ft (in some TERO locations), and setback regulations generally max 10 ft for certain faces. § 20.65.060

Practical guidance: overlays like TERO can substantially increase allowable height and density versus base zoning; always check overlay applicability on the Zoning Map and read the overlay’s Part in Chapter 20.65. Overlay district maps and rules are where you’ll confirm applicability.

Quick reference table — most decision‑relevant numeric standards

How to interpret standards and related processes (practical synthesis)

• Setbacks and height numbers in Title 20 are district‑specific; for standard residential builds pull the row for the exact zoning label (e.g., R‑1‑8) from § 20.30.200 rather than relying on generic “R‑1” rules.
• Mixed‑use and Urban Village districts use FAR and du/acre as the primary intensity controls (both may apply simultaneously). The code requires you to compute mixed‑use FAR including both commercial and residential areas. § 20.55.040
• Some districts (notably MUN) have an Alternate standards pathway for small lot/no‑setback development; that pathway changes minimum lot area and frontage rules but requires concurrent review. § 20.55.104
• Overlays (like TERO, the Neighborhood Business Overlay, Affordable Housing Overlay) can supersede or modify base district rules — always check Chapter 20.65 for overlay rules that apply to your parcel. § 20.65.060
• Accessory Dwelling Units (ADUs) have their own development standards (max area, setbacks, heights) in § 20.80.175; ADU rules in Title 20 also work within state ADU law constraints, so review both local and state ADU rules. See the ADU rules § 20.80.175 and the city ADU page for ministerial process notes.

Also review parking rules in Chapter 20.90 for off‑street parking sizing and exceptions and the citywide design standards when your site is in an Urban Village — see the city parking page for applicant checklists.

Checklist

• Identify the parcel’s exact zoning designation (e.g., R‑1‑8, R‑M) and applicable overlays on the Zoning Map. Verify with Planning staff. § 20.30.200, § 20.65.050.
• Pull the numeric row from the correct district table (setbacks, height, driveway length, stories) — e.g., Table 20‑60 for residential § 20.30.200.
• Calculate FAR and du/ac for mixed‑use or urban village projects per § 20.55.040 and Table 20‑136.
• Check overlay provisions (Chapter 20.65) and note any superseding standards (TERO, Neighborhood Business overlays).
• If proposing an ADU, follow § 20.80.175 sizing, height, and setback rules and confirm state ADU constraints.
• Review parking requirements (Chapter 20.90) and determine whether any reductions/exemptions apply and if design review will be required.
• For downtown, Main Street, or Urban Village projects, check Citywide Design Standards and the district build‑to / frontage rules (e.g., Table 20‑151). § 20.75.110.
• Confirm if rooftop/mechanical height exceptions apply (Chapter 20.85).

Risks & Ambiguities

Plain‑English summary

San José’s Title 20 sets numeric rules by specific zoning labels (R‑1‑8, R‑2, R‑M, MUN, UV/UR/TR, etc.): look up the exact row for your parcel to get front/side/rear setbacks, driveway length, height, FAR and du/acre limits; overlays and Urban Village plans commonly change those numbers, and ADUs have their own permitted sizes and setback flexibilities under § 20.80.175.
