Petaluma — Parking

Q: What is the baseline number of automobile parking spaces I must provide for a retail store in Petaluma?

Use Table 11.1 to calculate baseline: General retail is 1 space per 300 sq ft of gross floor area; the requirement is set in § 11.060 and Table 11.1 .

Q: How many bicycle parking spaces are required for a new office building?

Bicycle parking must be at least 10% of the automobile spaces required for most uses; the ordinance also prescribes a 60%/40% locker‑to‑rack guidance unless the PBAC approves deviations (§ 11.090 ) .

Q: Can I provide required parking off‑site in Petaluma?

Yes — required car parking can be provided off‑site up to 600 feet from the primary entrance (bicycle parking up to 100 feet ), with the exact distance determined by the Community Development Director on a case‑by‑case basis (§ 11.040 ) .

Q: Do residential conversions to an ADU require replacement parking?

The ordinance text in Table 11.1 indicates no replacement parking required for conversions to accessory dwelling units or junior accessory dwelling units; verify project specifics with Planning (Table 11.1 , § 11.060 ) .

Q: What are the minimum loading berth dimensions I must design to?

Standard loading berth minimum is 45 ft long × 12 ft wide × 14 ft clearance ; special uses (e.g., hearses) have smaller minimums listed in § 11.120(A) .

Q: Will my parking plan need site plan approval?

Almost certainly — all parking facilities except those provided for permitted principal uses in the A, RR, R1, R2, and R3 districts require site plan approval under § 11.080 ; consult the Zoning map and Planning staff to confirm whether your use is a permitted principal use (§ 11.080 ) .

Q: Are showers required for employees at a new commercial building?

Employee showers are required where Table 11.2 triggers them by gross floor area for certain uses (office, retail, etc.); see § 11.090 and Table 11.2 for thresholds (and § 11.095 for possible modifications routed through PBAC) .

Overview

This page summarizes what the Petaluma Implementing Zoning Ordinance requires for off‑street parking, bicycle facilities, and loading. It is built directly from Chapter 11 (Parking and Loading Facilities, Off‑Street) of the Petaluma ordinance and related development standards; every rule below is tied to the controlling code section cited. For design, landscaping, and site‑plan interplay see Petaluma Development Standards and Design Review.

What the code controls (quick points)

The ordinance establishes purpose and definitions for off‑street parking and loading (§ 11.010, § 11.020) .
Required automobile spaces are set by a use‑based schedule (Table 11.1 / § 11.060) and may be adjusted by the Director or through permits (§ 11.065, § 11.105) .
Bicycle parking minimums, mix of lockers/racks, and employee showers are mandatory for many uses (§ 11.090, Table 11.2) .
Off‑street loading berth counts and dimensional standards are in Table 11.3 and § 11.120 .
Alternatives (shared lots, off‑site parking up to 600 ft, valet, reductions) are allowed under standards in § 11.040 and § 11.065/11.105 .

District-by-district (what changes by zoning district)

Notes: the ordinance treats many parking requirements by land use (Table 11.1) rather than by zone. Where district-specific rules exist the ordinance cites the district names explicitly — those are summarized below. If you need district rules not listed here, Verify with the jurisdiction.

A (Agricultural)

Purpose / typical uses: agricultural, very low‑intensity uses.
Parking regime: permitted principal uses in A are exempt from the normal site‑plan approval requirement for parking facilities noted in § 11.080; however required spaces are still determined by use/Table 11.1 (§ 11.080, § 11.060) .
Where it applies: parcels mapped A in Chapter 4 (zone map). Verify with the jurisdiction for parcel specifics.

RR (Rural Residential)

Purpose / typical uses: very low‑density residential.
Parking regime: parking for permitted principal uses in RR is one of the limited exceptions to site plan review (§ 11.080) — required spaces still come from Table 11.1 or specific residential formulas (§ 11.060) .
Practical note: access drives serving small numbers of dwellings have lower minimum widths (10–12 ft) (§ 11.070(B)) .

R1, R2, R3 (Single- & Multi‑Family Residential)

Purpose / typical uses: single‑family up to low/medium density multi‑family housing.
Parking regime:
- Residential parking counts use specific rules in Table 11.1 (single household, attached townhomes, multi‑household: often 1 covered + additional spaces per bedroom; multifamily bedroom‑based ratios; overall minimum of 1.5 spaces/unit sometimes referenced) (§ 11.060, Table 11.1) .
- Off‑street parking facilities in R districts cannot be designed so vehicles must back across a sidewalk when the lot has five or more spaces (§ 11.070(B)) .
- Parking provided for permitted principal uses in R1/R2/R3 are excepted from the normal site plan approval rule (§ 11.080) .
Practical where it applies: projects affecting porches/driveways/front setbacks must respect the restrictions on parking in required front/street‑side setbacks (§ 11.070(E)) .

Industrial / Business Park

Purpose / typical uses: manufacturing, processing, warehouses, business parks.
Parking regime:
- Table 11.1 sets use ratios for manufacturing/wholesale/warehousing (e.g., 1 space per 500 sf or per‑acre minimums for industrial zones) (§ 11.060) .
- Industrial/business park parking in excess of current employment needs can be reserved as landscaped area with Director approval (§ 11.070(J)) .
- Parking lots in these zones must meet lighting, paving, grading, and landscaping rules (see § 11.070(F–G) and Chapter 14) .

Planned Districts (Chapter 19 / PD)

Purpose / typical uses: site‑specific development standards approved via planned district.
Parking regime: Chapter 19 may adopt separate parking requirements; when a planned district standard is more restrictive it controls; otherwise Chapter 11 applies (§ 11.050) .

Municipal Parking Assessment Districts

Sites/structures located inside a municipal parking assessment district are exempt from providing on‑site parking (§ 11.035) .

Key standards and quick lookup table

Topic	Requirement (plain)	Code reference
Purpose / scope	Off‑street parking & loading to reduce street congestion; showers to encourage bike commuting	§ 11.010
Use-based automobile parking	See Table 11.1 (e.g., General retail 1/300 sf; manufacturing 1/500 sf; multifamily per bedroom rules)	§ 11.060 / Table 11.1
Bicycle parking minimum	Min 10% of auto spaces (25% for commercial recreation/community) and mix guidelines (60% lockers/secure, 40% covered racks)	§ 11.090
Showers (employee)	Table 11.2 sets showers by gross floor area for certain uses	§ 11.090 / Table 11.2
Off‑site parking allowance	Required parking can be provided up to 600 ft off‑site (bicycle parking up to 100 ft); Director determines allowed distance	§ 11.040
Shared parking reduction	Shared facility within 300 ft can supply required spaces; conditional reductions allowed (minor/major adjustments)	§ 11.040, § 11.065
Loading berth size	Typical berth: min 45 ft length x 12 ft width, 14 ft overhead (special cases smaller)	§ 11.120(A)
Site plan approval	All parking facilities except permitted principal uses in A, RR, R1, R2, R3 require site plan approval	§ 11.080
Parking lot design basics	Access aisle widths, sight distances, paving, drainage, lighting and landscaping rules	§ 11.070(A, C, F, G)

Practical guidance and interpretation

Start by matching your proposed use to Table 11.1 to get the baseline automobile parking count (§ 11.060) . For home projects, follow the dwelling/bedroom rules in Table 11.1 and note no replacement parking is required for conversion to ADUs or JADUs in the table text (§ 11.060) . See Petaluma ADUs for the ADU program interaction.
If your site is close to transit or you plan to provide bike/bus incentives, pursue a minor adjustment (up to 20% reduction) through the Director or a major reduction via Conditional Use Permit — support with a parking demand analysis (§ 11.040(D), § 11.065, § 11.105) .
Design bicycle parking to meet the 10% rule and the 60/40 locker‑to‑rack mix (case‑by‑case flexibility through PBAC) and provide showers per Table 11.2 when the use triggers them (§ 11.090) . The Petaluma Bicycle Advisory Committee (PBAC) must review deviations (§ 11.090, § 11.095) .
Expect site plan review for nearly all non‑residential parking and any parking facilities that are not the permitted principal use in the five listed zones (§ 11.080) . Coordinate with Design Review and Landscaping and Screening standards early because Chapter 14 landscaping rules apply to parking areas (§ 11.070, cross‑refs in Ch. 7) .
For loading, size berths to the minimums in § 11.120 and keep loading maneuvers on‑site; additional berths can be required if truck activity will spill into public streets (§ 11.100–11.120) .

Checklist

Identify the proposed land use and locate the matching row in Table 11.1 to calculate baseline auto parking (§ 11.060) .
Determine bicycle parking required (min 10% or 25% for commercial recreation) and plan locker/rack mix (§ 11.090) .
Confirm whether your site falls inside a municipal parking assessment district (exemption) (§ 11.035) .
Check if you can use shared/off‑site parking (up to 600 ft for cars, 100 ft for bikes) and get Director sign‑off (§ 11.040) .
For reductions >20%, prepare a professional parking‑demand study for a CUP (§ 11.040(D), § 11.065) .
Size and detail loading berths per § 11.120 and Table 11.3 (§ 11.100–11.120) .
Prepare site plan showing access aisles, sight triangles, grading/drainage, lighting, landscaping, EV readiness and stall dimensions (as required by Chapters referenced in § 11.070 and Ch. 7) .
Coordinate PBAC review if you seek bicycle‑parking deviations or shower modifications (§ 11.090, § 11.095) .

Risks & Ambiguities

Issue	Why it matters	What to verify
Exact per‑use counts in Table 11.1	Table entries contain many use‑specific numbers (retail, restaurant, multifamily formula); a wrong row gives a wrong parking count	Verify the correct Table 11.1 row for your precise use; consult § 11.060 and the official Table image in the ordinance
Which zones are “permitted principal uses” exempted from site plan approval	§ 11.080 provides an exception for A, RR, R1, R2, R3 — but applicability depends on the exact permit and use	Confirm the parcel’s zoning and whether your proposed use is a permitted principal use; contact Planning (Verify with the jurisdiction) (§ 11.080)
Off‑site distance allowed (0–600 ft)	Director discretion affects whether off‑site parking within 600 ft is acceptable (§ 11.040)	Ask the Community Development Director for the permitted distance for your application and rationale (§ 11.040)
Bicycle parking mix and PBAC routing	PBAC review is required for deviations; percent mixes are guidance but not absolute without PBAC sign‑off (§ 11.090)	Confirm PBAC expectations and whether lockers vs covered racks are feasible at your site (§ 11.090, § 11.095)
EV charging / Level 2 readiness	Ch. 7 references EV readiness and CalGreen; Chapter 11 references stall sizing only	Verify EV infrastructure requirements with Building Code (California Building Standards Code) and local Building Dept (Not found in retrieved materials in Chapter 11; see Ch. 7 references)

Plain-English Summary

Petaluma’s zoning code requires you to provide off‑street car parking, bicycle parking, and loading spaces based on the type of use (see Table 11.1 and Table 11.3), with bicycle parking set at at least 10% of auto spaces and specific locker/rack targets; reductions or off‑site/shared solutions are possible but require Director or permit approval (§ 11.060, § 11.090, § 11.040) .
