Overview

San Pablo’s zoning ordinance is codified as Title 17 (Zoning) and establishes base zoning districts, overlay/special districts, and the official Zoning Map for the City of San Pablo, California that together control allowable uses, densities, heights, and setbacks. See the city's general mapping and program-level overview at the San Pablo zoning & planning overview page. The ordinance organizes rules by district (base zones), supplemental overlay/special districts, and district-specific development standards and procedures (use permits, design review, etc.) (§ 17.01.010; § 17.26.030) .

How this page is organized

Below I summarize each base zoning district in Title 17 with the ordinance sections that control purpose, typical permitted uses, and the most decision‑relevant dimensional standards. Where the ordinance uses tables (e.g., Table 17.32-C, Table 17.34-B) I cite the controlling section rather than reproducing long code text. For site‑specific questions (lot corners, substandard parcels, overlay combinations) verify with the City; I flag gaps and verification steps at the end.

Base zoning districts — district-by-district

Note: the list of base districts is established in § 17.26.030 (Table 17-26-A) .

R-1 — Single-Family Residential District

  • Purpose: Implement single‑family neighborhoods; preserve low density (maximum ordinary density 12 du/acre) (§ 17.32.020) .
  • Typical permitted uses: single‑family dwellings, Accessory Dwelling Units (ADUs), accessory uses and home occupations (subject to ADU rules in Section 17.60.070) (§ 17.32.020; § 17.60.070) . See the San Pablo ADUs page for process notes.
  • Key dimensional standards: setbacks and substandard‑parcel rules are in Table 17.32‑C and § 17.32.050 (minimum parcel sizes, side yard formulas). Example: for a standard lot 5,000 sf / 50 ft width the first‑story side yard is an aggregate of 20% of parcel width to a max of 10 ft with at least 4 ft on one side; second‑story aggregate side yards are 18 ft total with minimums (§ 17.32.050; Table 17.32‑C) .
  • Where it applies: citywide where mapped on the zoning map; R‑1 substandard‑parcel rules govern small lots (§ 17.28.010; § 17.32.050) .

R-2 — Two‑Family Residential District

  • Purpose: Duplexes and low‑rise multifamily; maximum density 18 du/acre (§ 17.32.020) .
  • Typical uses: single‑family, duplexes, ADUs, accessory uses. Open space minimums are higher than R‑3/R‑4 (see § 17.32.070) .
  • Key dimensional standards: open space 350 sf/unit (minimum), setbacks as in Division IV and Table 17.32‑B (see § 17.32.040 and § 17.32.070) .

R-3 — Multifamily Residential District

  • Purpose: Medium density multifamily housing — maximum density 24 du/acre (§ 17.32.020) .
  • Typical uses: townhouses, apartments, condominiums, ADUs; accessory uses allowed (§ 17.32.020) .
  • Key dimensional standards: side‑yard aggregate equal to 20% of parcel width up to 25 ft with per‑story minimums (e.g., 5 ft each side for 1–2 stories; 8 ft each side for 3 stories) (§ 17.32.060) . Open space minimums: 300 sf/unit and private open space minimums apply (§ 17.32.070) .

R-4 — High‑Density Multifamily District

  • Purpose: High‑density housing near transit/centers — maximum density 48 du/acre (§ 17.32.020) .
  • Typical uses: higher‑rise apartments, mixed residential types; ADUs allowed. Development intended near transit nodes (§ 17.32.020) .
  • Key dimensional standards: side yard aggregate = 20% parcel width up to 25 ft with 12 ft min on each side for 4+ stories; open space rules apply (§ 17.32.060; § 17.32.070) .

RMU — Residential Mixed‑Use District

  • Purpose: Mixed residential/office/retail; designed for higher intensity residential plus complementary uses; maximum FAR 1.5 and max residential density 50 du/gross acre within FAR limits (§ 17.32.020) .
  • Typical uses: ground‑floor retail/office with apartments above; ADUs allowed where consistent with other rules (§ 17.32.020) .
  • Where it applies: mapped locations tied to general plan mixed‑use corridors and specific plan areas (§ 17.26.030) .

NC — Neighborhood Commercial District

  • Purpose: Small‑scale convenience retail and services; maximum FAR 1.0 (§ 17.34.020) .
  • Typical uses: shops, cafes, personal services, small offices; mixed‑use housing encouraged in neighborhood centers (§ 17.34.090) .
  • Key dimensional standards: Table 17.34‑B has parcel area, height and FAR guidance (minimum parcel 2,000 sf, max building 30 ft in NC) (§ 17.34.040; Table 17.34‑B) .

CR — Regional Commercial District

  • Purpose: Larger retail, regional goods and services; higher intensity commercial uses; maximum building height 50 ft, minimum parcel area 10,000 sf (Table 17.34‑B) (§ 17.34.040) .
  • Typical uses: supermarkets, larger retail, mixed uses (residential allowed when commercial FAR ≥ 0.5) (§ 17.34.040) .

CMU — Commercial Mixed‑Use District

  • Purpose: Mixed commercial and residential uses at moderate to higher intensities; Table 17.34‑B indicates office FAR 1.5, residential density up to 50 du/ac when permitted (§ 17.34.040) .
  • Typical uses: mixed‑use projects, higher intensity retail/office with housing above; design guidelines and FAR incentives apply (§ 17.34.110; § 17.34.100) .

IMU — Industrial Mixed‑Use District

  • Purpose: Industrial and employment uses with compatible office/mixed uses; maximum building height 65 ft in Table 17.34‑B (§ 17.34.040) .

  • Key dimensional standards: institutional development standards are in § 17.36.040 (example: maximum building height 27 ft, no minimum parcel area; specific setbacks rules) (§ 17.36.040) .

OS — Open Space District

  • Purpose: Parks, recreation, conservation lands; uses limited to public recreation and resource‑protection activities (§ 17.26.030) .

Overlay & Special Districts (high‑level)

  • The city has five primary overlay districts: D1 Hillside, D2 Priority Development Area (PDA), D3 Air Quality Health Risk, MF Multifamily Overlay, and CP Creek Protection; plus specific plans SP1 (23rd Street) and SP2 (San Pablo Avenue). The overlays supplement or supersede the base zone per § 17.38.010–020 (overlay rules) .
  • Important overlay highlights:
    • Hillside (D1): any structure >1 story requires Zoning Administrator review and geotechnical review; findings required to protect hillside (§ 17.38.030) .
    • PDA (D2): promotes higher density near transit and applies to mapped PDA areas (Rumrill Rd, 23rd St SP, San Pablo Ave SP) (§ 17.38.040) .
    • Creek Protection (CP): prohibits structures in floodways and requires finished floors above the 100‑year floodline (§ 17.38.070) .
    • Multifamily (MF): preserves existing multifamily where base zone changed; expansion must meet R‑3/R‑4 standards (§ 17.38.060) .
    • Designated Housing Element sites (HE): targeted parcels with ministerial/minor design review rights when projects meet affordability thresholds; see § 17.38.090 for parcels and by‑right/minor design review rules for 20% affordable units (§ 17.38.090) .

See the San Pablo Overlay Districts page for mapping context.

How uses and approvals are processed (brief)

  • The base zones map allowable uses into the use tables (Table 17.32‑A and Table 17.34‑A/B) using R/A/U/– designations; specific use rules live in Division V and Chapter 17.30 (rules for similar uses, temporary uses) (§ 17.32.030; § 17.30.030) .
  • Entitlements are decided by different authorities: the Zoning Administrator handles administrative approvals (plan check/zoning clearance, minor design review, administrative use permits), the Planning Commission handles conditional use permits, major design review, variances; appeals and legislative amendments are heard by City Council (§ 17.18.010; § 17.16.070) .
  • Minor adjustments, administrative use permits, and use permits have findings and notice rules—see Chapters 17.18 and 17.16 for procedures and timelines (§ 17.18.080; § 17.16.010 ff.) .

Checklist — what an applicant must satisfy (pre‑application to submittal)

  • Confirm property base zone and any overlay or specific plan designation on the adopted Zoning Map (Zoning Map adoption rules: § 17.28.010) .
  • Check base zone permitted uses in the use table for the relevant chapter (residential chapters 17.32, commercial 17.34, institutional 17.36) and any Division V special use rules (§ 17.32.030; § 17.34.030; § 17.36.010) .
  • Verify applicable development standards: density, FAR, height, setbacks, min parcel area (Table 17.32‑B/17.32‑C for residential; Table 17.34‑B for commercial) (§ 17.32.040; § 17.34.040) .
  • Confirm whether overlay district rules (D1/D2/D3/MF/CP/HE/SP1/SP2) change standards or require special studies (geotech, air quality, creek setbacks) (§ 17.38.010–090) .
  • Check parking requirements and shared parking allowance (see San Pablo Parking and § 17.34.100 FAR incentives for shared parking impacts) .
  • Determine whether the proposal requires design review (minor vs major) or conditional/administrative use permits; consult Chapter 17.18 and Chapter 17.16 for processing and notice rules (§ 17.18.010; § 17.16.070) .
  • If proposing housing, check ADU rules (§ 17.60.070) and HE overlay ministerial review allowances (§ 17.38.090) .
  • Identify required technical studies: stormwater compliance (Chapter 8.40), green infrastructure thresholds (Chapter 17.40), geotechnical reports in hillside overlay (§ 17.38.030) .
  • Prepare materials for completeness review and plan check; expect zoning clearance / plan check action by the Zoning Administrator for many non‑discretionary items (§ 17.18.020) .

Risks & Ambiguities

Issue Why it matters What to verify
Overlay vs. base zone conflicts Overlays may modify or override base standards (e.g., HE minimum density, CP creek rules) — grants or denies rights Confirm mapped overlays on the property and read relevant overlay section (§ 17.38.020–090) and the Zoning Map (§ 17.28.010)
Substandard parcels and lot creation Smaller lots trigger R‑1 rules or restrictions on new lot creation Use Table 17.32‑B and § 17.32.050; do not assume standard setbacks/densities apply without checking parcel area/width rules (§ 17.32.050; Table 17.32‑C)
Measurement & intrusion rules (height/setbacks) Measurement rules can change what fits on a lot Consult Chapter 17.46 (height and yard measurement) and specific table notes referenced in § 17.32.040 and § 17.34.040 — Verify with zoning staff for corner lots and street frontage situations (§ 17.32.040; § 17.34.040)
“Similar use” decisions Use tables are not exhaustive; zoning administrator can classify new uses If proposed use isn’t listed, a similar use determination (§ 17.18.040) may be required — verify likely outcome with pre‑application meeting (§ 17.18.040)
HE overlay ministerial thresholds Affordability triggers different review (minor design review/by‑right) For HE overlay parcels, confirm the list of APNs in § 17.38.090 and required affordability (% units) to qualify for ministerial review

Plain‑English summary

San Pablo’s Title 17 establishes base zones (R‑1 through R‑4, RMU, NC, CR, CMU, IMU, I, OS) that tell you what can be built where and the main limits (density, FAR, height, and setbacks). Overlay districts (hillside, PDA, creek protection, multifamily, HE, plus specific plans) layer extra rules on top of base zoning and can change review types or require technical studies. Always confirm the parcel’s mapped base zone and overlays on the adopted Zoning Map and check the specific tables/sections cited here before you design a project (§ 17.26.030; § 17.28.010; § 17.38.010–090) .

Information Gaps

  • Exact numeric front‑yard setback figures by base zone are contained in measurement tables referenced by § 17.32.040 and § 17.34.040 but the full Table 17.32‑B values and all Table 17.34‑B notes were not presented in full in the retrieved snippets. Verify with the City’s official published tables for parcel‑specific numbers. Not found in retrieved materials: complete Table 17.32‑B numeric list of minimum parcel areas for every residential tier.
  • The official, current graphic Zoning Map (PDF/image) was referenced by § 17.28.010 but the map file itself was not included here; verify exact parcel mapping with the City Clerk / planning maps.
  • Detailed parking rates by use were not recovered verbatim; consult the San Pablo Parking chapter/table for exact stall counts per use. Not found in retrieved materials (exact parking schedule).

Frequently asked questions

What can I build on an R-1 lot in San Pablo?

On a property zoned R-1, you may build a single‑family home and accessory uses including ADUs, subject to the R‑1 development standards and accessory rules. The district’s ordinary maximum density is 12 dwelling units per acre; setback and side‑yard rules for substandard parcels are in § 17.32.050 (Table 17.32‑C) (§ 17.32.020; § 17.32.050) .

What are San Pablo setback requirements for single‑family lots?

Setbacks depend on parcel size and zone. For R‑1 substandard parcels see Table 17.32‑C and § 17.32.050 (examples: a 5,000 sf/50 ft lot uses an aggregate first‑story side yard equal to 20% of parcel width with max 10 ft and at least 4 ft on one side). Measurement rules (how to measure front and side yards) are in Chapter 17.46 (§ 17.32.050; Chapter 17.46) .

Do I need design review for a new multiunit project in San Pablo?

Design review thresholds vary: minor design review and major design review are processed per Chapter 17.18 and the approving authority table in Chapter 17.16. Projects in certain overlays (e.g., HE) that meet affordability thresholds can qualify for ministerial/minor review—see § 17.38.090 for HE rules (§ 17.18.090; § 17.38.090) . See San Pablo Design Review for procedural detail.

Where do I find the zoning map to confirm my parcel’s zone?

The official map referenced by the code is the “Zoning Map for the City of San Pablo, California” — its adoption and interpretation rules are in § 17.28.010–020. Verify the current map with City planning staff or the City Clerk because map amendments occur by ordinance (§ 17.28.010) .

How does an overlay district affect what I can build?

Overlay districts supplement or override the base zone: where overlay provisions conflict with the base zone, the overlay prevails (see § 17.38.020). Examples: CP (Creek Protection) prohibits placing structures in floodways; D1 Hillside requires geotech and additional findings for >1‑story structures (§ 17.38.020; § 17.38.030; § 17.38.070) .

Can I build an ADU and what rules apply in San Pablo?

ADUs are allowed in residential zones and are governed by local rules and state ADU law. The San Pablo ordinance references ADU development standards in § 17.60.070; state ADU limits also apply (see California ADU law). For local dimensional/modification requirements consult § 17.60.070 and confirm parking and setback interactions with Division IV rules (§ 17.60.070) .

What densities and FAR can I expect in mixed‑use zones (RMU/CMU)?

- RMU: FAR 1.5 and max 50 du/acre (residential contained within the FAR) (§ 17.32.020) . - CMU: Table 17.34‑B shows office/non‑office FAR allowances and a maximum residential density (see § 17.34.040 and Table 17.34‑B) .

What is the process for an administrative use permit or a minor adjustment?

An Administrative Use Permit and Minor Adjustment are processed by the Zoning Administrator under Chapter 17.18 with notice rules from Chapter 17.16. The zoning administrator may impose conditions and can refer matters to the Planning Commission (§ 17.18.080; § 17.16.060) .

Are there special rules for projects near creeks or on a hillside?

Yes: the Creek Protection (CP) overlay prohibits structures in floodways and requires finished floors at or above the 100‑yr floodline (§ 17.38.070) and the Hillside (D1) overlay requires geotechnical reports and findings for multi‑story structures (§ 17.38.030) .

How do FAR incentives work if I want more floor area for a commercial project?

Under § 17.34.100 commercial projects may receive an FAR increase (up to 0.75 additional) if they provide public amenities, shared parking, or consolidate parcels; any FAR increase requires a use permit per that section (§ 17.34.100) . ---
