San Ramon Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

San Ramon's zoning and planning rules are organized in Title D — the city's Zoning Ordinance (often called the Unified Development Ordinance) and implemented by the Community Development Department, the Zoning Administrator, the Planning Commission and City Council. The ordinance divides rules into Divisions for applicability, allowed land uses and zoning standards, site planning and design standards, use-specific standards, resource-management rules, permit procedures, administration, and definitions—so you look to different Division/Chapter numbers depending on whether you need use tables, design rules, or permit steps. Key topics you will consult in the code are the residential, mixed‑use, commercial/industrial and special-purpose zone chapters; the citywide site-planning standards (setbacks, heights, FAR and parking); the permit and review procedures under Division D6; and the overlay and specific-plan provisions that can override base-zone rules. § D1-1, § D2-2, § D3-6, § D6-23

How San Ramon's code is organized

• Title D — Zoning is structured into Divisions and Chapters (Division D1 through Division D8). The Table of Contents lists: Division D1 (Applicability), Division D2 (Allowable Land Uses and Zoning Standards), Division D3 (Site Planning and Project Design Standards), Division D4 (Standards for Specific Land Uses), Division D5 (Resource Management), Division D6 (Planning Permit Procedures), Division D7 (Zoning Ordinance Administration) and Division D8 (Glossary/Definitions). See the ordinance TOC for the division layout § D (Title D Table of Contents) .
• For “what goes where”: use tables in Division D2 (Tables 2-1, 2-6, 2-8, etc.) to determine allowable uses and required land-use permits § D2-3 . Site and design rules live in Division D3 (general property standards, landscaping and parking) — for example, height rules are in § D3-6 and parking rules in Chapter D3-III § D3-III . Permit process steps (application filing, review, decision, expiration, changes and appeals) are in Division D6 and D7 (e.g., Development Plans, Architectural Review, Planned Development Permits, and Nonconforming rules) § D6-23, § D6-25, § D7-I .

Zoning district families

San Ramon uses familiar base-zone families plus tailored mixed‑use and special zones. Below are the principal zone families and how they function in the code (names and targets are the city's terms; bolded zones are the ordinance labels):

• Residential zones — base density/lot-size residential zones such as RS-12, RS-10, RS-7, RS-6, RS-D, and multifamily ranges RMH, RH, RVH (with explicit density ranges in du/acre). Minimum lot sizes, widths, and setbacks are spelled out in the residential tables (Table 2-3 and D2-8 development standards) § D2-8, Table 2-3 .

  • Example programmatic text: RMH (15–22 du/ac), RH (22–30 du/ac), RVH (30–50 du/ac) are used where townhouses/apartments and higher-density housing are planned § D2-8 .

• Mixed‑use zones — city-specific mixed-use districts with FAR and density ranges: MUR (Mixed‑Use Residential Emphasis), DMU-N (Downtown Mixed‑Use — North), DMU-S (Downtown Mixed‑Use — South), CCMU (City Center Mixed Use). These zones set minimum/maximum residential densities and sitewide FAR ranges tailored to downtown/City Center intensification § D2 (mixed‑use descriptions and FAR ranges) .

• Commercial/Office/Industrial — CR, CS, MC, OA, OL, CC, CT, M-1 (Medical Center), M-2 (Health Facility) and others. Nonresidential lot coverage, FAR and setbacks are collected in the commercial/office development tables (Tables 2-9/2-10) § D2 (Tables 2-9/2-10) .

• Planned Development — PD is a flexible zone allowing project-level standards and modifications (minimum PD site 10 acres, PD may adjust setbacks, coverage, height and parking except it cannot increase base density without complying with density‑bonus rules) § D2-? (PD zone standards), § D6-25 .

• Overlay zones — the code uses overlay modifiers such as -H (Height Limit), -IS (Interim Study), -L (Landmark) and -SH (Senior Housing); overlay rules live in Division D2 (Overlay Zones / D2‑VI) and can modify base-zone requirements § D2-VI . See the city's overlay summary for location‑specific overlays. San Ramon Overlay Districts

(Every named zone and its table entry is descriptive in the ordinance — consult the use tables in Division D2 for the exact permitted, conditional and prohibited uses § D2-3 .)

Citywide development standards

San Ramon organizes citywide standards into Division D3 — site planning and design. Below are the headline rules and where to find them.

• Setbacks and projections: Minimum front/side/rear setbacks vary by zone and are summarized in the zone development tables (e.g., Table 2-9, Table 2-10 and the residential table Table 2-3). Exceptions and allowed projections into setbacks are handled in Section § D3-10 (exceptions/projections) § D3-10, Table 2-3, Table 2-9 .

• Height: Base maximum heights are shown per zone in the development tables (examples: 55 ft, 40 ft, 35 ft appear in commercial/office tables) and height measurement/exception rules are in § D3-6 (Height Limits and Exceptions) § D3-6, Tables 2-9/2-10 .

• FAR and lot coverage: Nonresidential floor area ratio and lot‑coverage maxima are shown in the same zone tables (examples: 0.45 FAR, 25–30% lot coverage in several commercial/office zones) Tables 2-9/2-10 .

• Parking and loading: Off‑street parking standards, required ratios, dimensions and design live in Chapter D3-III (Parking and Loading). Refer to Chapter D3-III for stall counts, accessible parking, and when parking reductions or shared parking apply § D3-III . For a quick topic link on parking procedures and submittals, see the city’s parking entry. San Ramon Parking

• Landscaping, screening and driveways: Landscape design is in Chapter D3-II; screening, buffers and driveway/site‑access standards are in D3-II and D3-37 respectively § D3-II, § D3-37 . San Ramon Landscaping and Screening

• Design and architectural review: Architectural/design review rules (required reviews, criteria and post‑decision procedures) are in Division D6 — Architectural Review (e.g., § D6-22 and Development Plans § D6-23) and design criteria are cross‑referenced to Division D3 standards § D6-22, § D6-23 . See the city design-review overview for process detail. San Ramon Design Review

Note: specific numeric setbacks, heights and FAR vary by zone and are tabulated in each zone's development table — always confirm the table row for your zone (e.g., Tables 2-3, 2-9, 2-10) before designing § D2 (zone tables) .

Specific plans & overlays

• Specific plans and development agreements take precedence over conflicting Zoning Ordinance rules — the code explicitly states that a conflicting specific plan or development agreement controls where it applies § D1-3 (development agreements/specific plans priority) .
• The ordinance includes explicit PD (Planned Development) procedures to implement large master‑planned developments with modified standards (PD minimum net area 10 acres, PDs may modify setbacks/coverage/height/parking except to increase base density without using the density bonus procedure) § D6-25, § D6-25.B.1–4 .
• Overlays (see Division D2, Chapter VI) such as -H, -IS, -L, -SH can add or limit features in any base zone; the overlay chapter lists applicability and control mechanisms § D2-VI . San Ramon Overlay Districts

Building permits & review

• Required planning permits and the building-permit connection: The code requires that any land-use or planning permit required by the Zoning Ordinance be obtained before a grading or building permit is issued (the building permit will require plans consistent with the zoning approval) § D2-2.B .
• Common planning approvals you will encounter:
  • Minor/major Development Plan (Division D6, § D6-23) — Development Plans are required for most new development except single‑family homes and noncontroversial additions § D6-23 .
  • Architectural Review (Division D6, § D6-22) — required in many zones; criteria focus on site layout, architecture, landscape, public safety and compatibility § D6-22 .
  • Planned Development Permit (Major/Minor) — used to approve master/development plans and to modify standards where allowed; decision authority and notice procedures differ for Major vs. Minor PDs § D6-25 .
  • Variances, exceptions and appeals — administered under Division D7 (nonconforming uses, appeals, enforcement) and the Variance chapter — see Division D7 for appeal deadlines and enforcement § D7-I, Division D7 . San Ramon Variances and Exceptions
• Timing, expiration and changes: Planning approvals expire if not exercised in a prescribed period, may be extended by the Zoning Administrator (typically up to three 12‑month extensions) and changes to approved projects follow the code’s “changes to an approved project” rules § D6-35, § D6 (extensions) .
• Where to start: file an application with the Community Development Department per Division D6 (Permit Application Filing and Processing) — the Zoning Administrator checks completeness; some applications may be routed to Planning Commission for public hearing § D6-1, § D6-23 .

For sign rules, historic preservation rules, nonconforming use rules, and signage specifics see the respective chapters in Division D3, D7 and the appendices: San Ramon Signage San Ramon Historic Preservation San Ramon Nonconforming Uses

State housing law in San Ramon

Summary: state housing statutes (ADU/JADU streamlining, SB 9 lot splits/duplex approvals, and density‑bonus law) interact with San Ramon’s local code. Local rules must comply with state law; where the municipal code has specific implementing chapters they apply, otherwise state law controls.

• Density bonus: San Ramon includes a Density Bonus chapter in Division D4 (Division D4, Chapter VIII — Density Bonus) so density‑bonus requests are administered locally per the municipal procedure § D4-VIII .
• Accessory dwelling units (ADUs) and JADUs: The San Ramon zoning code excerpts provided do not show a dedicated local ADU section in the retrieved materials. For statewide minimums and limits on local ADU rules (size, setbacks, parking exemptions, detached ADU height) consult California ADU law and the state ADU handbook. The state ADU guidance (2025 update summary) explains limits local agencies may not impose (for example, minimum ADU size/coverage/parking restrictions and base height rules) — see the California ADU handbook excerpt provided (state law summary) § (state guidance) . For San Ramon-specific ADU submittal standards, check the city's ADU page and contact Planning staff; the municipal ADU implementing section was not found in the retrieved ordinance materials (Not found in retrieved materials) . San Ramon ADUs California ADU law
• SB 9 / lot splits and duplexes: The retrieved San Ramon ordinance excerpts do not contain explicit SB 9 implementing language. Where state law (SB 9) applies, the city must follow statutory ministerial procedures; local code language that departs from SB 9 would not be effective to block qualifying SB 9 projects. If you plan to use SB 9, confirm current local ministerial checklists with Planning staff (Not found in retrieved materials).
• Rent control / rent stabilization: The municipal code excerpts in the materials provided did not show any local rent‑control ordinance or a reference to rent‑stabilization; if you need a definitive answer, verify with the City Clerk or the municipal code online (Not found in retrieved materials).

Practical orientation — how to use this overview

• Step 1 — Identify the zoning for your parcel (Zoning Map) and then read the zone’s table row in Division D2 to learn permitted/conditional uses and required permit types § D2-3, Tables 2-x .
• Step 2 — Consult the applicable development standards table for that zone (setbacks, height, FAR, lot coverage) and Division D3 for how those measurements are defined § D3-6, Tables 2-3 / 2-9 / 2-10 .
• Step 3 — Check overlays and any specific‑plan or development‑agreement language that may control the parcel (specific plans override conflicting zoning provisions) § D1-3 .
• Step 4 — Match the required planning permit (ministerial vs discretionary). For ministerial work (typical small ADU or a building permit for a conforming project) file for building/grading permits after any required planning clearance; for discretionary proposals prepare to apply for Development Plan, Architectural Review or Planned Development § D6-23, § D6-25 .
• Step 5 — Use the Zoning Administrator and Community Development staff early — they determine completeness and can often route a minor application without Commission hearing § D6-23.D .
