Overview

This page summarizes what Lafayette’s municipal zoning/planning ordinance (Title 6, Planning and Zoning) actually requires about zoning: the defined zoning districts, typical permitted uses, and the most decision-relevant dimensional/development controls and overlays that affect what can be built. It synthesizes the Lafayette code text into plain-English guidance and points you to the controlling code sections for verification. Verify parcel-specific rules with the city; some items (zoning map image, parcel-level overlays) are not included in the retrieved materials (see Information Gaps).

How the ordinance works (quick)

  • Lafayette organizes land by named map symbols and zoning articles (examples: R-6, R-10, R-12, R-15, R-20, R-40, R-65, R-100, L-R-5/L-R-10, M-R-O, M-R-T, M-R-B, C, C-1, RB, SRB, PHC). The base rules for each district (uses, density, setbacks, height, parking) are in Title 6. See the Title-6 root for administration and procedure in general (§ 6-101 et seq.) .
  • Many projects are also subject to Lafayette’s objective development standards and design review processes; when design review applies it is mandatory before permits are issued — read Lafayette’s design review rules for triggers and submittal requirements. See Lafayette Design Review for process details and submittal requirements. (§ 6-271 et seq.) .
  • Parking rules are district-specific and implemented through Chapter 6-6; consult the district parking schedules and the city’s parking chapter for exact counts. See Lafayette Parking for those details. (§ 6-890; Chapter 6-6) .

Note on links used above: development standards, parking and design review are discussed in the ordinance and the links point to the GoCodebook menu pages for those topics.

District-by-district breakdown

Below are Lafayette districts that are present in the municipal code files retrieved. Each subsection lists the purpose, typical permitted uses, key dimensional standards (front setback, side/rear, height, lot area/width where stated), and where it generally applies (when the code states this). All statements are grounded in the Lafayette Municipal Code; citations to the exact controlling § follow each item.

R-6 (Single-family residential — map symbol R-6)

  • Purpose & typical uses: detached single-family dwelling and accessory uses; limited farming/parks/home occupations and supportive care are allowed; some uses require a land use permit (§ 6-703, § 6-704) .
  • Dimensional standards: minimum lot area 6,000 sq ft (§ 6-705); height limit 35 ft / 2.5 stories (structures over 30 ft require design-review commission findings) (§ 6-708) .
  • Setbacks and yards: aggregate side-yard minima and rear-yard minima are specified (see § 6-709 – § 6-711) .
  • Where it applies: all land designated R-6 on the city’s zoning map (map symbol R-6) — verify parcel zoning with the city. (§ 6-703) .

R-10 (Single-family residential — R-10)

  • Purpose & typical uses: single-family dwellings, accessory structures, residential care for the aged (small), home occupations, supportive care; other uses may require land use permits (§ 6-721—6-723) .
  • Dimensional: lot size, setbacks and other minima are defined in Article 2 for R-10 (see § 6-705–§ 6-713 for related standards in single-family articles) .
  • Design review/limits: projects exceeding district thresholds or height triggers may require design review (§ 6-1903). .

R-12, R-15, R-20, R-40 (Single-family residential — R-12, R-15, R-20, R-40)

  • Purpose & typical uses: all are single-family districts allowing detached dwellings and accessory uses, with variations in minimum lot width/depth/side-yard aggregates and parking. See the article for each district: e.g., R-12 uses/lot-width rules (§ 6-746—§ 6-753) and R-15 setbacks/side-yard rules (§ 6-767—§ 6-773) .
  • Dimensional highlights: R-12 often requires larger average width and depth than R-6 (see § 6-746 et seq.); R-15 requires front setback 20 ft and aggregate side yards 25 ft (§ 6-769, § 6-768) .
  • Where it applies: consult the zoning map for parcel-level district identification (verify with city).

R-65 and R-100 (Low-density single-family — R-65, R-100)

  • R-65: front setback 25 ft (corner principal frontage 25 ft, other frontage 20 ft), rear yard 15 ft, and two parking spaces required per unit (§ 6-7129—§ 6-7131) .
  • R-100: front setback minima are larger (see district text); rear yard 30 ft; livestock and small farming explicitly allowed; two parking spaces per dwelling (§ 6-7141—§ 6-7151) .

L-R-5 / L-R-10 (Low Density Residential — L-R-5, L-R-10)

  • Purpose: preserve semi-rural character, protect natural resources; uses include single-family homes, small farming and livestock consistent with Chapter 6-5; minimum lot sizes and large setbacks apply (§ 6-7182—§ 6-7211) .

Multiple-family / Mixed districts (M-R-A, M-R-B, M-R-O, M-R-T)

  • M-R-O (Multiple-family / Professional Office): allows duplexes, multi-family, professional offices, medical uses, limited child care; parking schedule and open-space minimums are specified (e.g., 30% open space, parking one space for one-bedroom units, § 6-863, § 6-873—§ 6-875) .
  • M-R-T (Transit/ TOD-style): height capped generally at 25 ft (§ 6-886); open-space requirement 50% and parking standards like 1.5–2 spaces per unit for bedrooms are listed (§ 6-885—§ 6-890) .
  • M-R-B: has its own density, lot-area minima and dimensional standards (e.g., height 35 ft, lot area minima for new lots) — see Article for specifics (§ 6-846—§ 6-849, § 6-849—§ 6-852) .
  • Where these districts allow reduced setbacks, FAR or lot-coverage exceptions, the planning commission may impose conditions or use design review to ensure compatibility (see design review rules and the district articles) .

Commercial & Retail Districts (C, C-1, C-1-60, RB, PHC, SRB)

  • C / C-1 / C-1-60: general commercial uses are permitted (retail, service, medical in specified subareas, residential dwelling units in some areas); some uses require a land use permit; building/site design and parking rules apply (§ 6-921—§ 6-924, § 6-981—§ 6-984) .
  • RB (Retail Business), PHC (Pleasant Hill Road Commercial), SRB (Specific retail block / BART Block): have special rules on open space, step-backs, frontages on Mt. Diablo Blvd., and parking/loading that differ from general commercial districts (see Articles for the SRB/BART Block special plan language) (§ 6-971—§ 6-973, § 6-975.13—§ 6-975.15) .

Overlays and special maps

  • Hillside Overlay District: mapped overlay with additional density, clustering and building-site slope rules (e.g., building site slope maximum of 30%; clustering and exceptions are in §§ 6-2046—§ 6-2047) .
  • Viewing Evaluation Map, Lafayette area ridge map, and other adopted maps are referenced in definitions and are on file at city offices; overlay limits and mapped boundaries (including BART Block specific plan areas) control additional restrictions such as setback, clustering, and prohibitions on certain variances (§ definitions and map-adoption statements) .
  • If a property sits in multiple districts/overlays, the code specifies how to reconcile overlapping standards (e.g., exterior setbacks are those of underlying zoning; lot divider rules extend least-restrictive district 30 ft into a more restrictive district in similar transitions — § 6-2046, § 6-509) .

Accessory Dwelling Units (ADUs)

  • ADUs and JADUs are governed by a dedicated article (Article 3, §§ 6-560—6-569) that implements California ADU law while preserving local objective standards. Class A/B/C ADU categories are defined, size and setback rules are provided, and some ADU types are ministerial (no discretionary review) (§ 6-560, § 6-563, § 6-566) .
  • Key ADU highlights you must check: side/rear setbacks may be as small as 4 ft for many ADUs (§ 6-566(b)(1)); detached ADUs have specific height caps (typical 16–18 ft with exceptions, attached ADUs up to 25 ft) (§ 6-563(b)); the city will not require correction of unrelated nonconforming conditions in some ADU approvals (§ 6-568) .
  • ADUs may also trigger parking exceptions (no parking required in specific circumstances) — consult the ADU article for the parking exceptions and the ADU bonus program (§ 6-569, § 6-566(f)) .
  • For ADU technical compliance you must also follow the California Building Standards Code (Title 24) — see California Building Standards Code for building-level requirements (separate page). Link to Lafayette ADUs for practitioner-oriented detail.

Checklist — what an applicant must satisfy (typical)

  • Confirm the parcel’s zoning and any overlays with the city (zoning map / Hillside overlay / BART Block). Verify mapped overlays per § 6-2046 and definitions (maps on file at city) .
  • Assemble a site plan, vicinity map, building footprints, driveway & parking layout — design-review applications must include these (see design review submittal list § 6-273) .
  • Confirm district-specific setbacks, height, lot coverage and FAR limits in the applicable Article (eg. R-6 § 6-705—§ 6-709, R-65 § 6-7129) and check if planning commission approval or a variance will be needed .
  • If proposing an ADU, confirm which ADU class applies and follow Article 3 (ministerial or ADU-permit rules); record required deed restriction before CO when applicable (§ 6-560—§ 6-569) .
  • Provide required parking per district and review Chapter 6-6 for exceptions (ADU parking exceptions & transit exceptions are in § 6-566(f) and § 6-563) — see Lafayette Parking. .
  • If design review is triggered (e.g., >17 ft in many residential areas, or district-specified triggers), prepare materials per § 6-273 and expectation checks per § 6-274; schedule public notices if required (§ 6-277) .
  • Where a deviation is necessary, consider a variance or land-use permit following Part 1 procedures (§ 6-1) and verify whether the specific section is listed as “modifiable” or excluded (e.g., BART Block limits where variances are prohibited in certain subsections § 6-975.15) .

Risks & Ambiguities

Issue Why it matters What to verify
Overlay applicability (Hillside, BART block, Viewing Evaluation, ridgeline) Overlays change density, siting, clustering, hillside building-site slope, and may prohibit some variances (§ 6-2046, § 6-975.15) Verify mapped overlay boundaries with the Planning Department and request official map exhibits on file at city offices; confirm which overlay rules control.
Parcel-specific nonconformances Existing nonconforming setbacks or structures can limit what a new project must change (ADU and SB9 rules make some allowances) (§ 6-568, § 6-3811) Verify recorded conditions, previous permits, and whether nonconforming features are grandfathered; confirm whether the city requires corrections for ADU approvals.
Design review triggers Height (>17 ft in many single-family zones), changes visible from public property, or multi-family projects trigger design review and possibly hearings (§ 6-1903, § 6-272) Confirm whether the proposed project meets the design-review thresholds and the authority that will hear the application.
Parking calculations vs. transit exceptions ADU and other parking requirements can be waived near transit or under special conditions; wrong assumptions can cause an application denial (§ 6-566(f), § 6-563(3)) Confirm block-level transit proximity, existing car-share availability, and whether on-street parking rules apply.
Zoning map image & parcel lines The ordinance refers to maps on file but does not reproduce the full zoning map in the retrieved materials Request the official zoning map or GIS parcel/zoning layer from the Planning Department; verify any recent rezones (see § 6-555).

Plain-English Summary

Lafayette’s zoning code (Title 6) assigns every parcel to a named zoning district (for example R-6, R-10, M-R-O, C-1), and each district spells out permitted uses, minimum lot sizes/setbacks, height caps, parking, and whether design review or a land use permit is needed; overlays (Hillside, BART Block, etc.) add extra siting and slope rules — always confirm your parcel’s exact zoning/overlays and follow the cited sections below for the concrete rule text. (§ 6-703, § 6-7129, § 6-563, § 6-2046)

Frequently asked questions

What can I build on an R-6 lot in Lafayette?

You may build one detached single‑family dwelling and accessory structures; some uses (e.g., greenhouses >300 sq ft, a second unit, medical offices) require a land use permit. Dimensional rules set minimum lot area (6,000 sq ft) and limit height to 35 ft (structures over 30 ft trigger design review). See §§ 6-703, 6-704, 6-705, 6-708.

What are Lafayette’s setback requirements for single-family zones?

Setbacks vary by single‑family district: for example R-15 and R-12 generally require a 20 ft front setback (§ 6-769, § 6-749) while R-65 requires 25 ft front (§ 6-7129). Corner-lot rules often set a lower secondary frontage setback (see each district article). Verify the exact district article for your parcel.

Do I need design review in Lafayette?

Possibly — design review applies by district and project characteristics (multi‑family or downtown commercial, single‑family projects over 17 ft, or projects that will be visible from public property). The design review article lists triggers and required submittal materials (§ 6-272—§ 6-273) and evaluation criteria (§ 6-274).

How do ADU rules work in Lafayette?

ADUs are governed by an Article that implements California ADU law: some ADUs are ministerial; others require an ADU permit. Typical local rules allow 4 ft side/rear setbacks in many cases, detached ADU heights often 16–18 ft (with transit-based exceptions), and deed restrictions/recording steps apply before occupancy in some cases (§ 6-560, § 6-563, § 6-566). See the ADU article for class A/B/C distinctions and exceptions.

How many dwelling units are allowed on one Lafayette parcel?

That depends on the zoning and which program you use; for SB 9 / housing-development/urban-lot-split rules the code states no more than two total units per parcel for SB9-created parcels, and different caps apply for housing developments (see § 6-3808) — always check the specific article and whether an urban lot split or other program is used.

What parking will the city require for my residential project?

Parking is district-specific and set in Chapter 6-6 and the district articles (examples: M-R-O: one space per one-bedroom unit, M-R-T parking schedules in § 6-890). ADU statute in the code also includes parking exceptions near transit and in certain other conditions (§ 6-566(f)). Consult the district article and Chapter 6-6.

What special rules apply if my lot is in the Hillside Overlay District?

Hillside overlay rules limit allowable building‑site slope (generally ≤30% for suitable building sites), call for clustering in subdivisions, and impose special siting/landscape/grading standards; exceptions and clustering rules are in §§ 6-2046—6-2047. You must provide topographic surveys and may need additional findings for exceptions.

If my proposed project doesn’t meet a numeric standard, can I get a variance?

Yes, the code provides variance and land-use permit procedures under Part 1; however certain sections are expressly non-modifiable for specific areas (for example some provisions in the BART Block specific plan cannot be varied — see § 6-975.15) and variances need findings. Check the "modifiable sections" language in the specific article and follow the Part 1 variance procedures.

Do Lafayette’s rules let me keep small farm animals?

Yes — keeping small farm animals (chickens, rabbits, bees with rules) is allowed in many single-family districts and in L-R districts subject to size and animal-count limits; see Chapter 6-5, Article 6 and district lists for specifics (§ 6-591—§ 6-593, § 6-523).
