San Leandro — Development Standards

Last reviewed: July 2, 2026

Overview

This page summarizes the development-standards rules that appear in the City of San Leandro Zoning Code (setbacks, heights, lot coverage, density/FAR, daylight planes, and related accessory/ADU standards). It focuses only on what the local zoning ordinance actually prescribes; where the code is silent or parcel-specific, I flag that you should Verify with the jurisdiction. For the city's zoning map and base rules see the San Leandro Zoning information.

Notes on citations: every numeric standard below references the controlling code section (the § number) and the uploaded Zoning Code excerpts used to prepare this page. The file-search snippets are indicated inline using the provided file citation markers.

District-by-district breakdown

Each district subsection below lists: purpose/typical uses (short), the most decision-relevant dimensional rules, and where those rules appear in the San Leandro Zoning Code.

Residential districts (R): RS, RD, RM-3000, RM-2500, RM-2000, RM-1800, RM-875, RO, RS-40, RS-VP

• Purpose / typical uses: single- and multi‑family housing types and accessory residential uses; ADUs regulated separately. See residential base rules in the R District chapters. Design review or additional approvals may apply for some multi‑unit projects — check local procedures.
• Setbacks (typical): Front setbacks are generally 20 ft in many R districts (e.g., RS and RD) and 15–40 ft in specific subdistricts where noted; side yards often 5 ft (minimum) and rear yards typically 15 ft; corner‑side values and district exceptions are listed in the table of minimum yards. See § 2.04.316.
• Height: typical maximum 30 ft in many R districts (RS, RD); RS-VP and some RO subrules set alternate height measurement or lower maximums (e.g., 18 ft in the RS‑VP subdistrict). See § 2.04.320.
• Daylight plane / bulk controls: For RD, RO, RS, RS‑40, RS‑VP parcels a daylight plane begins at 19'‑6" above side setback and slopes 45° inward; use this plus the height limit to determine the allowed building envelope (§ 2.04.324) — rooftop equipment may be exempt as stated in code.
• Lot coverage: RS and many R districts: 50% maximum lot coverage; RO has a lower rate (about 33⅓%) with additional rules for wide lots — see § 2.04.328 and § 2.04.376 for RO specifics.
• Accessory structures: footprint and height rules for accessory buildings are specific (exemptions for very small structures, and step‑up setbacks and heights — e.g., up to 0 ft allowed for very small exempt structures; greater setbacks for taller accessory structures). See § 2.04.348.
• ADUs: ADUs/JADUs have detailed, ministerial standards (maximum areas, no parking required for ADUs, minimum 4 ft side/rear setbacks for ADUs, detached ADUs must keep 5 ft separation from other structures). ADU-specific height caps (e.g., 16 ft for detached ADU, different limits for attached/repurposed) apply; see § 2.04.388. For the state rules that also affect ADUs consult the California ADU law.

Practical guidance: For a single‑family lot expect to design to the 20 ft front, 5 ft side (min), 15 ft rear, 30 ft height, and 50% coverage regime unless the parcel lies in a different R subdistrict or has nonconforming neighbors where averaging rules apply (§ 2.04.316; § 2.04.320; § 2.04.328).

Commercial / Downtown / Special Activity districts: CC, CN, CS, CR, DA‑1..DA‑6, NA‑1/NA‑2, SA‑1..SA‑3

• Purpose / typical uses: retail, commercial, mixed‑use, and targeted downtown Transit‑Oriented Development (DA) and neighborhood activity (NA/SA) sites. Downtown DA districts include special height and street‑front rules intended to implement the Downtown TOD strategy.
• Setbacks and street interface: basic front/side/rear yard rules for commercial districts are in the commercial chapter; DA districts have tailored front setbacks tied to street sections and pedestrian zone widths (e.g., along East 14th St a 7 ft minimum front setback to create a 15‑ft pedestrian zone in specified locations; ground‑floor residential often set back 10–15 ft). NA‑2 has 20–25 ft front setbacks depending on height, and side/corner side setback rules tied to building height. See § 2.08.308.
• Height: DA districts have specific height frameworks and some parcels meeting state Public Utilities criteria may be allowed up to 7 stories without a conditional use permit where state law applies; see § 2.08.312. Downtown height allowances are nuanced — consult the code for site‑specific allowances.
• Lot coverage: Commercial district maximum coverage varies — CC, CN, CS, P: 50%; CR: 25%; many DA/NA/SA subdistricts list 100% coverage (i.e., no coverage limit) for appropriate downtown subareas — see § 2.08.316.
• Adjacency limits / daylight plane: where these districts abut R districts, daylight plane and step‑back rules apply to limit bulk toward residences (see the required daylight plane illustrations and § 2.08.308).

Practical guidance: downtown/mixed‑use projects must check the DA subarea rules and the pedestrian/street‑section standards early (these directly change front setback and sidewalk requirements).

Industrial districts: IG, IL, IP, IT

• Purpose / typical uses: general, light, industrial park, and technology‑oriented industrial uses; mixed performance, with landscaping/site standards for IP.
• Setbacks: Typical minimums in many I districts are Front 10 ft (IG/IL/IT) and 20 ft front for IP; side and rear may be 0 ft in some I districts but check the table in § 2.12.308. Additional setbacks apply at specific streets (e.g., Doolittle Drive requires 20 ft front/corner‑side). See § 2.12.308.
• Height: baseline heights are often 35 ft for IG, IL, IP, IT, with special limits when within 100 ft of an R district (reduced to 25 ft within 100 ft), and an administrative adjustment may allow up to 50 ft in some I districts via the Zoning Enforcement Official. See § 2.12.312.
• Lot coverage / FAR: IG/IL/IT typically allow up to 75% lot coverage and 1.0 FAR, IP typically 40% coverage and 0.8 FAR; exceptions and calculation rules are in § 2.12.316.
• Landscaping: minimum site landscaping percentages are required for I districts (e.g., IG/IL/IT: 5%, IP: 15%). See § 2.12.320.

Practical guidance: industrial development near residential neighborhoods must pay careful attention to the within‑100‑ft height limit and the increased yard rules when height rises above 20 ft in IG/IL/IT (the code increases front/corner‑side yard requirement as buildings get taller).

B‑TOD / Transit‑Oriented Subareas (B‑TOD Sub‑Areas 1–3)

• Density: Minimum density standards apply to multi‑family and mixed‑use projects in B‑TOD subareas — e.g., Sub‑Area 1 = 65 du/acre, Sub‑Area 2 = 60 du/acre, Sub‑Area 3 = 20 du/acre (with limited exceptions for Sub‑Area 3). See § 2.10.316.
• Lot coverage / open area: maximum coverage and minimum open area are provided; lot coverage may be as high as 80% with minimum 20% open area in these mixed‑use districts; administrative exceptions possible. See § 2.10.320.

Practical guidance: these zones enforce minimum density as well as lot‑coverage/open‑area rules — both must be shown on plans.

Key standards at a glance

If you rely on the table above for a specific parcel, Verify with the jurisdiction: site‑specific overlays, easements, floodplain, or historic zoning may override base figures. See the Overlay Districts guidance.

Checklist

• Confirm zoning district for parcel (city zoning map) and any overlay districts. Verify with Planning staff.
• Show measured building height and method used (finish‑grade reference) consistent with § 1.12.108 definitions (Verify with the jurisdiction). Not found in retrieved materials: the full definition text for "Height".
• Dimensioned site plan showing front/side/rear setbacks per district (§ 2.04.316; § 2.12.308).
• Demonstrate compliance with daylight plane where applicable (§ 2.04.324; daylight plane rules for C/DA adjacency in § 2.08.308).
• Calculate lot coverage and FAR per district rules and exemptions (cornices, open-sided roofs, etc.) (§ 2.04.328; § 2.12.316).
• For multi‑family or B‑TOD projects, show density calculations (minimums in § 2.10.316) and open‑area calculations (§ 2.10.320).
• If proposing ADU: follow ADU rules (setbacks, max size triggers for FAR/coverage, no parking required) in § 2.04.388 and be aware that state ADU law also applies. Link to ADUs.
• Confirm landscaping/screening minimums (chapter references and I‑district minimum site landscaping) (§ 2.12.320; Chapter 4.16). See San Leandro Landscaping and Screening.
• If proposing deviations (setback, height, coverage), identify process: Administrative Exception or Planning Commission review per the noted sections (e.g., Administrative Exceptions § 2.10.408 / site plan rules). See San Leandro Variances and Exceptions.

Risks & Ambiguities

Plain-English Summary

San Leandro's zoning code sets district‑specific numeric rules: residential yards are typically 20 ft front, 5 ft side, 15 ft rear with 30 ft height and 50% lot coverage; commercial/downtown (DA) zones and industrial zones have their own height, setback, and FAR/coverage rules (industrial examples: IG/IL/IT typically 35 ft height, 75% coverage, 1.0 FAR). ADUs have their own ministerial rules (setbacks, size limits, no parking required) and daylight plane and adjacency rules further limit massing near residences. Always check overlays, DA/TOD subarea standards, and the code's specific § citations listed below before final design.
