Larkspur — Parking

Last reviewed: July 2, 2026

Overview

This page summarizes what the Larkspur zoning ordinance requires for parking, loading, bicycle parking, and parking-area design and landscaping. The primary rules live in the off-street parking and loading chapter and are applied by district: Chapter 18.56 is the controlling chapter for counts, design, accessible spaces, EV spaces, loading and landscaping, and district chapters (for example 18.20, 18.28, 18.41, 18.44) reference and apply those standards. See Larkspur’s zoning menu for broader context on how these rules fit into the city's permitting framework. § citations below point to the exact code provisions and the Larkspur Zoning file where those provisions appear.

NOTE: This page stays within Title 18 (zoning). Requirements from the California Building Standards Code (Title 24) are not addressed here. The page also links to the city's rules on setbacks and development standards, design review, overlay districts, ADUs, landscaping and screening and historic preservation because those rules commonly affect how and where parking is sited.

How the code is organized (short)

• Chapter 18.56 — Off‑Street Parking and Loading: counts, calculations, accessible parking, loading, bicycle parking, EV parking, dimensional and landscape/ screening standards, and tables. § 18.56.010 – .160.
• Each zoning district chapter (for example 18.20 R‑1, 18.28 R‑2, 18.32 R‑3, 18.41 SD, 18.43 GD, 18.45 TD, 18.44 C‑1, 18.48 C‑2, 18.52 L‑1) contains a short clause tying new construction, structural alteration or change of use to Chapter 18.56 and, in some districts, special exceptions. See the district excerpts below for specifics.

District‑by‑district breakdown (how Chapter 18 applies in each district)

Below are the Larkspur zoning districts that commonly come up in parking decisions. Each subsection summarizes the district purpose, typical uses, where the ordinance ties parking to Chapter 18.56, and any district‑specific parking notes or exceptions.

R‑1 — First Residential District (Chapter 18.20)

• Purpose & typical uses: One‑family dwellings and uses that preserve low‑density residential character. § 18.20.005 – .020.
• Parking rules: When a new dwelling is constructed or a main building is structurally altered or the use substantially changed, minimum off‑street parking must follow Chapter 18.56. § 18.20.100 requires application of Chapter 18.56 standards.
• Key dimensional/parking notes: In all R Districts, one‑half of required (non‑guest) parking must be covered and paving in front yards is limited (see § 18.16.115 and § 18.56.150 for surfacing/dimension rules). § 18.16.115; § 18.56.150.

R‑2 — Second Residential District (Chapter 18.28)

• Purpose & typical uses: Medium‑density residential (one‑ and two‑family dwellings, ADUs, group homes). § 18.28.005 – .020.
• Parking rules: Off‑street parking for new dwellings and changes of use is governed by Chapter 18.56 (see § 18.28.100).

R‑3 — Third Residential District (Chapter 18.32)

• Purpose & typical uses: Higher‑density residential. § 18.32.
• Parking rules: Uses and new constructions must meet Chapter 18.56 minimums (see § 18.32.100). Guest/usable outdoor area rules are district‑specific; parking calculations still follow § 18.56.100.

T‑R — Tidelands Residential District (Chapter 18.22)

• Purpose & typical uses: Low‑lying tidelands; physiographic constraints. § 18.22.
• Parking rules / exception: Because of shoreline constraints the code explicitly states off‑street parking per Chapter 18.56 is not required in the T‑R district unless the Planning Commission finds that it is physically possible to provide off‑street parking and that it is necessary. § 18.22.100.

SD — Storefront Downtown (Chapter 18.41)

• Purpose & typical uses: Historic, pedestrian‑scaled downtown retail, restaurants, offices, and some residential above ground floor. § 18.41.010.
• Parking rules: New construction/structural changes are subject to Chapter 18.56 minimums; residential units above first‑story commercial have specific parking direction (1 space per unit for above‑first‑story units). § 18.41.100 & § 18.41.150.

GD — Garden Downtown (Chapter 18.43)

• Purpose & typical uses: Mixed downtown uses with lower building coverage and more surface parking. § 18.43.
• Parking rules: Chapter 18.56 controls; district includes a development plan trigger at 5,000 gsf and then requires a parking plan addressing disabled, loading and bicycle standards per § 18.43.140–.150. § 18.43.150 references rates and calculation approach in § 18.56.100.

TD — Transitional Downtown (Chapter 18.45)

• Purpose & typical uses: Preserve pedestrian‑scaled historic character while allowing modern commercial uses, surface parking. § 18.45.010.
• Parking rules: New/additional floor area must provide parking on site or, with a use permit, off‑site or contribution to a parking assessment district; rates for retail/restaurant/office/residential for additions are stated in § 18.45.150 (which draws from § 18.56.100).

C‑1 — Restricted Commercial (Chapter 18.44) and C‑2 — Commercial (Chapter 18.48)

• Purpose & typical uses: Neighborhood/commercial uses (retail, service, offices). § 18.44, § 18.48.
• Parking rules: When new buildings are constructed, or use/structure is changed, off‑street parking and loading must comply with Chapter 18.56; a noted exception: residential units above first‑story commercial have a specific requirement of one parking space per dwelling unit in some downtown/commercial districts (see § 18.44.100).

A‑P — Administrative & Professional (Chapter 18.40)

• Purpose & typical uses: Office, professional uses. § 18.40.
• Parking rules: New construction/changes of use follow Chapter 18.56 minimums (§ 18.40.100).

• Purpose & typical uses: Light industrial and related service uses. § 18.52.
• Parking rules: Off‑street parking and loading for new buildings/structural changes must conform to Chapter 18.56 (§ 18.52.100).

MHP — Mobile Home Park (Chapter 18.30)

• Purpose & typical uses: Mobile home parks (affordable housing). § 18.30.
• Parking rules: Off‑street parking standards are referenced to Chapter 18.56 where applicable; mobile home park standards may include lot/unit parking specifics within chapter text. Verify project‑specific requirements with the City. § 18.30 and § 18.56.

Key technical standards (what the code requires on a practical level)

• Minimum counts: Use the tables in § 18.56.100 for residential (by bedroom and tenure) and commercial use rates; for new construction the code lists specific rates (retail/service, restaurant, office, residential, hotel). § 18.56.100.
• Guest parking: Guest parking rules are set out in § 18.56.110 and apply in addition to unit counts. § 18.56.110.
• Calculation and alternative compliance: The Planning Commission or Community Development Director can apply similar‑use determinations, allow joint‑use, or let a project pay into off‑site parking (parking assessment district) or provide a use permit for off‑site solutions. See § 18.56.025, § 18.56.050, and district-specific parking permit provisions. § 18.56.025–.050; district references (e.g., § 18.45.150).
• Bicycle parking: Nonresidential development must provide short‑term racks for visitors and secure long‑term parking for employees/tenants per § 18.56.140 (design, anchoring, location). § 18.56.140.
• Loading: Off‑street loading berths are required per building use and gross floor area (Table 18.56‑I). § 18.56.130.
• Accessible parking: Follow State and ADA requirements; accessible stalls count toward minimums and may be required to be added without variance even if this reduces conformity. § 18.56.120.
• Design dimensions & compact car rules: Stall and aisle dimensions, compact car layouts and minimum surfacing/drainage/slope rules are in § 18.56.150 and supporting tables. § 18.56.150 and Tables 18.56‑II/III.
• Landscaping & screening: For parking lots >5 stalls and parking lots ≥12 stalls there are screening/landscape and irrigation/tree requirements (10% landscaping minimum and 1 tree per 6 stalls). § 18.56.160.

Practical guidance / application notes

• Always start with § 18.56.100 for counts; then check the zoning chapter for the property (for example 18.20, 18.28, 18.41, 18.44) for district‑specific language (exceptions, in‑lieu, or specific per‑use clauses).
• If your parcel is within 1/2 mile of transit, check § 18.56.115 for reduced parking eligibility; the City still may impose minimums if certain findings are made. § 18.56.115.
• ADUs: ADU parking is governed by Chapter 18.23 (ADU rules, including exemptions for ADU parking in many cases: historical district, within 1/2 mile of transit, car share proximity, etc.). See § 18.23 and § 18.56.100 for interaction. Larkspur ADUs and § 18.23.
• For downtown historic areas (for example SD), parking is frequently constrained and the code allows one‑space‑per‑unit rules for residential above commercial; check Heritage Preservation overlay rules when siting parking because these overlays can restrict surface parking or require design review. See § 18.41.100 and Heritage Preservation chapters.
• Loading and deliveries: Loading berth requirements are use/size‑based (Table 18.56‑I) — plan loading locations to avoid conflicts with pedestrian corridors and adjacent R districts because screening/ buffering rules apply. § 18.56.130; § 18.56.160.

Checklist

• Determine zoning district for the parcel and read that chapter (e.g., 18.20, 18.28, 18.41, 18.44).
• Use § 18.56.100 to calculate required off‑street vehicle parking and § 18.56.110 for guest parking.
• Confirm loading berth requirements from § 18.56.130 (Table 18.56‑I).
• Provide bicycle parking per § 18.56.140 (short‑term and long‑term ratios + anchoring).
• Check accessible parking requirements § 18.56.120 and ensure ADA/stall dimensions are provided and counted.
• Prepare a parking plan showing surfacing, aisle/stall dimensions, drainage, screening/landscape islands and irrigation per § 18.56.150–.160.
• Verify whether parking reductions apply (e.g., ADU exemptions § 18.23, transit proximity § 18.56.115).
• If proposing off‑site parking, shared parking, or contribution to a parking district, get the required use permit or City approval per the district rules and § 18.56.050.

Risks & Ambiguities

Plain‑English summary

If you build, change use, or add floor area in Larkspur you must meet the off‑street parking counts and design rules in Chapter 18.56 (counts for homes, retail, restaurants, offices; bicycle racks; loading berths; accessible and EV spaces) unless a district chapter gives a specific exception (for example the Tidelands T‑R district). ADU parking has its own chapter with common exemptions. Always check the parcel’s specific zoning chapter and bring a parking plan showing stalls, circulation, ADA spaces, bike racks and landscaping when you apply. § 18.56.100 et seq.; district chapters (e.g., 18.20, 18.28, 18.41, 18.44).
