Livermore — Development Standards

Last reviewed: July 2, 2026

Overview

This page summarizes what the Livermore Planning and Zoning Code (LPZC) actually requires for development standards — setbacks, heights, lot coverage, density/density bonuses, and related site controls — organized by the city’s zoning districts. It focuses on ordinance requirements (not Title 24 or building-code matters) and points you to where the code requires site plan approval, design review, and parking studies. For municipal rules on parking consult the Livermore parking page; for design-review procedures see the Livermore design review page. Also note overlay and PD rules described under the city’s overlay districts guidance and the landscaping and screening requirements that commonly interact with yard/setback rules.

How to read this page

• Every numeric standard below is tied to the LPZC section that contains it (we quote the controlling § number) and include the file citation to the retrieved ordinance text. Verify site- or parcel-specific interpretations with the Planning Division. If a standard could not be confirmed in the retrieved materials, the text explicitly says "Not found in retrieved materials."

RL — Low Density Residential (RL family: RL-5, RL-6, RL-7, etc.)

Purpose & typical uses

• The RL district is intended for low-density single-family residential development (single-family homes and accessory uses). See LPZC § 2-16-010 for the district purpose.

Key dimensional standards (typical / highlights)

• Front yard: varies by RL subtype; consult the district table in LPZC § 2-16-040 (district subtypes and lot development regs). Not all subtype front yards are printed in the retrieved excerpt; verify with Planning. Not found in retrieved materials for every RL subtype.
• Site plan / design review: Site plan approval and design review are required for projects in many RL cases before building permits can issue (see LPZC § 2-16-040 and the general site plan rules at § 4-10-030).

Where it applies

• City residential neighborhoods designated low-density in the zoning map and the district list under Chapter 2-16.

Practical note

• RL is a family of districts — always check the RL-* suffix on the zoning map and the specific lot development table referenced by § 2-16-040.

R‑R — Rural Residential (e.g., R-R-1, R-R-3, R-R-5)

Purpose & typical uses

• Rural single-family lots and agricultural/residential uses; the district is oriented to large-lot, low-impact residential/agriculture. See LPZC § 2-13-010 et seq.

Key dimensional standards (by example)

• Lot area: R-R-1 = 40,000 sq ft, R-R-3 = 125,000 sq ft, R-R-5 = 210,000 sq ft per § 2-13-050.
• Front yard: 30 ft (each of R-R-1 / R-R-3 / R-R-5) per § 2-13-060.
• Side yards: one side 20 ft; both sides total 45 ft for each listed R-R subtype (§ 2-13-060).
• Rear yard: 50 ft (§ 2-13-060).
• Maximum site coverage: 25% (§ 2-13-080).
• Maximum height: 35 ft for principal buildings (§ 2-13-090).

Where it applies

• Large-lot parcels and areas mapped R-R on the zoning map (Chapter 2-13).

Practical note

• R‑R setbacks and lot widths are large by design; accessory agricultural structures may carry different setbacks (see § 2-85-050(D) for agricultural setbacks near other zoning districts).

RG — General Residential (examples: RG-16, RG-14, RG-12, RG-10)

Purpose & typical uses

• Single-family and small-scale residential development in varying lot sizes/density bands. See LPZC § 2-25-050 for the RG lot and development table.

Key dimensional standards (as shown in the code table)

• Minimum lot area: RG-16 = 6,000 sq ft, RG-14 = 6,500 sq ft, RG-12 = 7,500 sq ft, RG-10 = 9,000 sq ft (table in § 2-25-050).
• Front setback: 20–30 ft depending on subtype (see table in § 2-25-050).
• Lot coverage: RG-16 = 50%, RG-14 = 40%, RG-12 = 35%, RG-10 = 30% (§ 2-25-050).
• Height envelope: Height is tied to setbacks from non-street property lines with a stepped formula in § 2-25-050(C); taller buildings require deeper side/rear setbacks depending on adjacent zone types (see § 2-25-050(C)(1–3)).

Where it applies

• Typical single‑family neighborhoods mapped RG-* on the zoning map; consult § 2-25-050 for the exact lot‑by‑lot standards.

Practical note

• The RG height/setback relationship is prescriptive: if you propose a wall higher than 10 ft you must calculate non‑street setbacks using the formulas in § 2-25-050(C).

CS — Community Serving Commercial (CS)

Purpose & typical uses

• Community-serving retail/office and mixed uses intended to service neighborhoods. See LPZC § 2-31-010 et seq.

Key dimensional standards

• Minimum lot size: none (§ 2-31-050(A)).
• Minimum street frontage: none except 25‑ft easement if no street frontage (§ 2-31-050(B)).
• Minimum frontage yard (street): 25 ft, must be landscaped (§ 2-31-070(A)).
• Maximum site coverage: 50% (§ 2-31-080).
• Maximum building height: Generally 35 ft, may be allowed up to 50 ft with a conditional use permit or where FAA or other policies allow (§ 2-31-090).

Other requirements

• Site plan approval is required prior to development (§ 2-31-060). Off-street parking must be provided per Chapter 3-20 (§ 2-31-100).

I‑2 / I‑3 — Industrial Districts (e.g., I‑2 light industrial; I‑3 heavy industrial)

Purpose & typical uses

• Industrial, manufacturing, and related service uses with performance standards to protect adjacent uses. See Chapter 2-61 (I‑2) and Chapter 2-64 (I‑3) summaries.

Key dimensional standards

• I‑2 maximum building coverage: 45% (§ 2-61-070).
• I‑2 height & setbacks: Detailed yard/height tables are in the chapter sections (e.g., § 2-61-060 / § 2-61-070); site plan and design review are required prior to development (§ 2-61-060(A)).
• Performance standards: noise, pollution, vibration caps and screening rules are spelled out in § 2-61-080 and similar sections.

Practical note

• Industrial zoning often adds performance standards and additional landscaping/screening requirements; check the I‑zone chapter for buffers to R districts.

SLV‑AG — South Livermore Valley Agricultural (SLV‑AG)

Purpose & typical uses

• Agricultural production and large‑lot agricultural uses in the South Livermore Valley. See LPZC Chapter 2-85.

Key dimensional standards

• Minimum lot size: 100 acres (§ 2-85-040(A)).
• Minimum street frontage: 100 ft (§ 2-85-040(B)).
• Yards: Front 30 ft; Side 20 ft; Rear 50 ft (§ 2-85-050(A)(1–3)).
• Maximum site coverage: 20% (§ 2-85-050(B)).
• Height: 40 ft for principal buildings; up to 100 ft for agricultural‑related or public structures with a conditional use permit (§ 2-85-050(C)).

Other requirements

• Site plan and design review required before building/grading permits (§ 2-85-060). Accessory structure design references point to LPZC § 3-05-150.

PD — Planned Development (PD‑R, PD‑C, PD‑I)

Purpose & typical uses

• PD zones substitute site‑specific regulations approved by ordinance and are used for larger, master‑planned residential, commercial or industrial projects. See LPZC § 2-76-080 through 2-76-120.

Key dimensional standards / how they work

• PD ordinances must state the permitted uses, lot sizes, yards, site coverage, height, parking and open space as the zoning regulations for the PD area (§ 2-76-080(B) and § 2-76-100(A)(2)).
• Because PD regulations are set by the adopted PD ordinance, the “default” base‑zoning standards are replaced: always read the specific PD ordinance text (the ordinance “restates all the standards and requirements for the district”). See § 2-76-120.

Practical note

• A PD allows negotiated variations from conventional standards in exchange for design features or public amenities; every PD has its own numeric rules — check the adopted PD ordinance language cited on the zoning map.

DR — Design Review Combining District (DR)

Purpose & typical uses

• The DR combining district authorizes discretionary design review over site/building/landscape design and allows modification of development standards only within findings limits (§ 2-73-060).

What it changes

• Standards subject to discretionary modification include minimum yards, setbacks, maximum floor area, maximum height, open space, and architectural treatments — but the code forbids relaxing standards below the baseline code minimums (§ 2-73-060(C)).

Practical note

• If your property is mapped with a DR combining district, expect design review and the possibility that the city will require findings on compatibility and visual policies before allowing deviations. See § 2-73-060(D) for the mandatory findings.

Quick Standards Table (decision‑relevant snapshot)

Checklist

• Verify the parcel’s exact zoning and any combining districts (DR, TDC, PD) on the city zoning map (chapter references: § 2-13, § 2-16, § 2-25, § 2-76).
• Confirm lot-specific numeric standards in the district table that applies to your lot (e.g., § 2-25-050 for RG; § 2-13-050 for R‑R).
• Prepare site plan package showing setbacks, heights, parking, landscaping and open space per LPZC § 4-10-040.
• Demonstrate off‑street parking compliance per Chapter 3-20 (parking requirements referenced throughout the district chapters).
• Determine whether your property is subject to design review or PD standards; if so, follow the Livermore design review process and findings in § 2-73-060 and § 4-10-050.
• If proposing deviations, prepare a variance or PD amendment application and evidence supporting the required findings (§ 4-15-010 for variances; § 2-76-080 for PD).

Risks & Ambiguities

Information Gaps

• No citywide FAR table or uniform FAR values for base zoning districts found in the retrieved materials. Not found in retrieved materials.
• Complete RL subtype numeric tables and some RL front setbacks were not fully present in the excerpts; verify full § 2-16-040 text. Not fully present in retrieved materials.
• Detailed measurement rules for height on sloping lots and all exceptions require reading § 3-05-270 through § 3-05-300 in full. Only chapter index appeared in the retrieved materials.

Plain‑English Summary

If you want to build in Livermore, first check the parcel’s zoning and any combining districts — each zone in the Livermore code spells out front/side/rear setbacks, max site coverage, and height (e.g., R‑R requires 30 ft front, 50 ft rear, 25% site coverage, 35 ft height, per § 2-13-060–2-13-090) and many projects must pass site plan approval and design review before a permit is issued (§ 4-10-030, § 2-73-060) . Verify any PD or DR overlay standards that supersede base zoning for your parcel.
