San Leandro Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

San Leandro’s Zoning Code (the “Zoning Code of the City of San Leandro”) is organized to implement the General Plan and any adopted specific plans by dividing rules into base districts, overlays, citywide rules, administrative procedures, and housing-specific rules; the Code is codified on eCode360 and identifies where map boundaries, permitted uses, and development standards live (§ 1.04.100; § 1.08.100) . At a practical level, zoning decisions are handled through ministerial zoning permits for by‑right work, administrative exceptions, and clearly scoped discretionary tracks (site plan, use permit, development plan) administered through Chapters in Title 5 (§ 5.04.100; § 5.12.100; § 5.14.100) . State housing laws are folded into local rules via specific chapters—for example ADU rules are implemented locally to reflect Government Code requirements (§ 2.04.388) . Where citywide performance, parking, and building rules matter, those standards are collected in the Code’s cross‑cutting chapters and referenced to the local building and parking chapters (§ 4.04.340; off‑street parking chapter reference) .

How San Leandro's code is organized

• High level structure: the Zoning Code is divided into Titles (General Provisions; Base District Regulations; Overlay District Regulations; Regulations Applying in All or Several Districts; Administrative Regulations; Affordable Housing Regulations) and then Chapters and Sections; this layout is stated in the Code’s organizational rules (§ 1.08.100) .
• Map + text: The regulatory text and the zoning map work together; the map locates the districts and the text prescribes uses and development standards for each district (§ 1.04.104) .
• Types of rules:
  • Land use tables live in the Base District Regulations (Title 2) and in overlay chapters (Title 3) (§ 1.08.100) .
  • Development standards (height, setbacks, coverage) are in Title 2 for base districts and Title 4 for rules that apply across districts (§ 1.08.100) .
  • Administrative procedures for permits, hearings, appeals, interpretations, and fees are in Title 5 (§ 5.04.100 et seq.) .

Zoning district families

San Leandro separates districts into familiar families (residential, commercial, industrial and special mixed‑use/transit districts) plus overlays:

• Residential families and subtypes (examples in the Code): the RO (Residential Office) and multiple R (single‑ and multi‑family) variants with numeric suffixes governing lot size, coverage and accessory rules (see accessory and additional dwelling rules in the RO and R chapters) (§ 2.04.380; § 2.04.348) .
• Commercial/professional family: CC, CN, CR, CS and related downtown/transit areas DA‑1, DA‑2, DA‑3, DA‑4, DA‑6, NA‑1, NA‑2, and SA‑1/2/3 — these district names and the fact that their development regulations are collected together are shown in the commercial district development rules (§ 2.08.300) .
  • The downtown/transit districts (DA‑1 through DA‑6) implement the Downtown San Leandro Transit‑Oriented Development Strategy and include ground‑floor retail expectations and mixed‑use emphasis (§ 2.08.300; DA district summaries) .
  • The North Area Specific Plan is referenced as required guidance for NA‑1/NA‑2 development (§ 2.08.300) .
• Special districts: B‑TOD (large TOD areas where Development Plan approval can be required), business park and industrial districts are handled in Title 2 and tied to specific plan text where applicable (§ 5.14.104; § 2.08.300) .
• Overlays and targeted tools: the Code includes Conservation Overlays (“‑CV”), a H Housing Overlay (shown as an “H” on the map), and S Special Review Overlay among others; overlays are additive to a base district and modify permitted uses or standards (§ 3.12.124; § 3.38.104; § 3.16.100) .
• Historic/landmark treatment: the Code provides a Landmark/Conservation District track administered through the Library‑Historical Commission and a specific review and plan requirement for L Districts (§ 3.28.120; § 3.28.124) .

(Throughout the preceding list district names and plan labels above are shown as they appear in the Code; consult the zoning map for parcel‑level zoning assignments § 1.04.104) .

Citywide development standards (how to read them)

• Where the rules are: citywide performance and cross‑cutting site rules (noise, dust, glare, refuse storage, mechanical screening, driveway visibility, and related standards) are in the Regulations Applying in All or Several Districts (Title Z4 / Chapter 4.04) — see the performance standards and related cross‑cutting rules (§ 4.04.340 et seq.) .
• Typical dimensional controls: each base district chapter lists the district‑specific lot area, lot width, setbacks, maximum height, and lot coverage; for commercial/professional districts those tables and standards are collected in § 2.08.300 and following sections (§ 2.08.304 etc.) .
• Lot coverage and accessory rules: residential lot coverage caps and accessory structure allowances (example: coverage caps of 50%, 60%, 70% tied to specific R district designations; accessory size limits and setbacks) are specified within the R/RO chapters (§ 2.04.348; § 2.04.380) .
• Height exceptions and daylight plane rules are handled in Title Z4 where cross‑district exceptions to height limits are described (§ 4.04.320 et seq.) .
• Parking: parking rules and required parking rates are collected separately (Off‑Street Parking and Loading Regulations) and are referenced by the performance standards and development review chapters; the Code explicitly references the off‑street parking chapter when controlling lighting and parking design (§ 4.04.340; Chapter 4.08 reference) . See the City’s parking rules for required stall counts and design parking.
  • Note: the Code also contains ADU‑specific parking relief: no parking spaces are required for ADUs/JADUs and no replacement parking is required when a garage/carport is converted (§ 2.04.388) .
• Design and site standards: design expectations for specialized areas (Downtown Design Guidelines, East 14th Street guidelines, North Area Specific Plan) are invoked within district development sections to control façades, ground‑floor uses, and pedestrian interface (§ 2.08.300; DA district text) .

(If you want to look up a single numeric standard—height, setback, lot coverage—for a parcel, find the base district on the zoning map and then read that district’s development regulations in Title 2; cross‑check any overlay modifications in Title 3) (§ 1.04.104; § 1.08.100) .

Design and discretionary review

• Design review / site plan / development plan:
  • Small projects and ministerial permits are handled as zoning permits by the Zoning Enforcement Official (§ 5.04.104; § 5.04.108) .
  • Site Plan Review (Chapter 5.12) governs projects that require design review and public noticing; see the site plan review standards and appeal rights (§ 5.12.100; § 5.12.124) .
  • Development Plan Approval is the public, Planning Commission review track for large or special projects (e.g., five or more acres in B‑TOD) and includes required findings tied to General Plan and specific plans (§ 5.14.100; § 5.14.104; § 5.14.124) .
• Findings and conditions: discretionary approvals (use permits, development plans) require findings about consistency with the General Plan, compatibility with surrounding uses, and physical suitability; conditions may be imposed to protect public health and safety (§ 5.14.124; § 5.14.128) .
• Appeals and lapse: decisions are appealable under the appeals chapter and discretionary approvals lapse if not built within the Code’s time limits unless extensions are granted (§ 5.14.132; § 5.14.136) .

For practical guidance on design review steps, timelines and submittal requirements consult the City’s design review page and the site plan/development plan chapters design review.

Specific plans & overlays (where local nuance matters)

• Downtown and East 14th: the DA‑ family (DA‑1 through DA‑6) implements the Downtown San Leandro Transit‑Oriented Development Strategy; DA‑1 requires ground‑floor retail on specified corridors and DA districts include targeted scale/density directions (§ 2.08.300; DA district descriptions) .
• North Area Specific Plan: the NA‑1/NA‑2 districts call out consistency with the North Area Specific Plan in commercial development rules (§ 2.08.300) .
• Overlays:
  • Conservation Overlay (‑CV): used to protect neighborhood character; an overlay includes a Neighborhood Conservation Plan and modifies the base district; building permits must conform to the adopted plan (§ 3.12.124; § 3.12.128) .
  • H Housing Overlay: when adopted the H overlay is combined with base zoning to explicitly permit Mixed‑Use Residential and Multi‑Family Residential uses while generally retaining base district development standards (§ 3.38.104; § 3.38.108; § 3.38.112) .
  • S Special Review Overlay: intended to provide discretionary review for special areas such as the Marina Automall and similar sites, and is applied by ordinance (‑S on the map) (§ 3.16.100; § 3.16.104) .
• Historic overlays/landmarks: Landmark District (L District) designation process, conservation plans and the Library‑Historical Commission’s role are described in the L District chapter (§ 3.28.120; § 3.28.124) .

See the Code’s overlay chapters for the specific ordinance that established the overlay and the map annotation rules; overlay adoption is by ordinance and shown on the zoning map (§ 3.12.124; § 3.38.104) . For summary maps and parcel‑level overlays consult the planning counter or the zoning map (§ 1.04.104) .

Building permits & review (the path from plan to permit)

• Zoning permit first: most projects require a zoning permit application showing compliance; the Code explains the general application requirements and the Zoning Enforcement Official’s authority to accept/deny and to refer to discretionary tracks (§ 5.04.104; § 5.04.108) .
• Ministerial vs. discretionary:
  • Ministerial permits (e.g., many residential building permits and ministerial ADU approvals) are handled without public hearing, subject to objective standards (§ 2.04.388; § 5.04.124—note CEQA applicability for discretionary actions) .
  • Discretionary approvals (use permits, variances, Planned Developments, development plans) require public notice/hearing and findings by the Planning Commission or City Council per Title 5 (§ 5.08.116; § 5.14.116) .
• Environmental review and fees: CEQA review is required for discretionary projects that are not ministerial or categorically exempt; fees are set by resolution and referenced in the zoning administration chapters (§ 5.04.124; § 5.04.128) .
• Lapse and extensions: permits and approvals have lapse periods (e.g., development plans generally lapse after two years unless a building permit or certificate of occupancy is obtained) and the Code provides for extension processes (§ 5.14.136; § 5.04.116) .

Practical takeaway: submit complete zoning/building plans to the Zoning Enforcement Official; simple, objective projects (including many ADUs) are processed ministerially and faster, while larger or non‑standard projects must follow the Site Plan/Development Plan/use permit process and public noticing is required (§ 5.04.104; § 2.04.388; § 5.12.116) .

State housing law in San Leandro

San Leandro’s Code expressly implements several California housing laws, and other state programs are implemented through chapters:

• ADUs/JADUs: the ADU chapter implements Government Code §§ 65852.1/65852.2 and treats ADUs/JADUs as ministerial where objective standards are met; ADU rules cover location, number allowed, setbacks (minimum 4 ft side/rear for ADUs), height caps (typical detached ADU 16 ft, with 18 ft near major transit), no parking requirement for ADUs/JADUs, and ministerial review within 60 days for complete applications (§ 2.04.388) . See the City ADU page for practical checklists ADUs and the statewide rule set California ADU law.
• Density bonus: San Leandro’s Density Bonus chapter implements State Density Bonus Law (Gov. Code § 65915 et seq.), applies in all residential‑allowing districts, and awards the state‑required bonus and incentives when developments qualify (§ 6.08.100; § 6.08.112) .
• SB 9 / duplex‑lot split (two‑unit law) and other newer ministerial lot‑split/ministerial multi‑unit laws: specific local references to SB 9‑style ministerial lot splits or ministerial two‑unit provisions were not located in the retrieved Zoning Code excerpts; verify current implementation or local objective design standards with the City (Not found in retrieved materials).
• Rent control/tenant protections: the municipal Zoning Code excerpts do not establish rent‑control rules; those would typically appear elsewhere in the Municipal Code if adopted (Not found in retrieved materials).
• Building code interface: all building work must comply with the California Building Standards Code (Title 24) as adopted locally; the Zoning Code references the Building Code for building‑permit level compliance and makes procedural connections between zoning permits and building permits (§ 5.04.120; ADU building‑permit ministerial timing) . See the statewide building code reference California Building Standards Code.

If your project relies on a specific state housing provision (SB 35, SB 328, SB 9, density bonus) check the particular local implementing ordinances or contact the Planning Counter to confirm any objective design standards or local overlay rules required by the City (local implementation varies by ordinance and date) (§ 1.08.116—projects in process; § 5.16 amendments) .

Information gaps and verification

• The retrieved Zoning Code excerpts clearly show ADU rules, density bonus implementation, overlay types, and the structure of administrative chapters. However, I did not find an express local ordinance text implementing SB 9‑style ministerial lot splits or any local rent‑control ordinance in the materials provided (Not found in retrieved materials). Confirm with the City Clerk or Planning Division for post‑2024 ordinances or stand‑alone Municipal Code chapters on rent and tenant protections.
• For parcel‑level numeric standards (exact front/setback/height/FAR for a specific parcel), consult the zoning map plus the specific base district section in Title 2 and any applicable overlay ordinance (§ 1.04.104; § 1.08.100) .
