Mariposa County — Parking

Last reviewed: July 6, 2026

Overview

In unincorporated Mariposa County, minimum off-street parking is regulated by Title 17 Zoning and a set of supplementary standards that apply countywide unless a specific zoning district provides its own rules. Most uses follow the countywide ratios and stall dimensions in the off‑street parking standard, while certain commercial and industrial districts apply plan-based or external standards. This page interprets the ordinance for practical application and ties each rule to the controlling § of the code, within the broader context of the county’s zoning framework and development standards.

Core rule: Outside of the commercial/industrial plan districts noted below, the County’s default off‑street parking standard requires two spaces per dwelling, one per 300 sq ft of retail, one per 1,000 sq ft of wholesale, plus one per employee; each space must be 10' x 20'. See § 17.108.120.

Countywide Off‑Street Parking Rules (Title 17)

Applies in unincorporated areas across all zones except where a district is expressly carved out (see district notes below).

• Minimum ratios and stall size:
  • Residential: 2 spaces per unit. Stall size: 10 ft by 20 ft minimum. Surfacing: residences are exempt from the crushed rock surfacing requirement; other parking must be surfaced with a minimum of two inches of crushed rock. Administration: the Planning Commission may increase minimums for specific sites after a hearing if demand warrants it. § 17.108.120.
  • Retail: 1 space per 300 sq ft gross floor area. § 17.108.120.
  • Wholesale: 1 space per 1,000 sq ft gross floor area. § 17.108.120.
  • Employees: add 1 space per employee (owner counts as an employee). § 17.108.120.
• Applicability carve‑outs: These standard ratios do not apply in the CG‑1, CG‑2, CR, M‑1, and M‑2 districts, which rely on plan-based or external criteria described below. § 17.108.120.
• Parking and setbacks (countywide): Driveways are permitted within setbacks, and the code allows certain structures (e.g., garages, carports, sheltered parking) in yard areas under conditions set in the structure location rules. § 17.108.130(A)(4).
• Definitions you will see on plans:
  • Parking lot/area: an area not in a building used for off‑street parking. § 17.148 (definitions).
  • Parking space: a dedicated, unobstructed space with access to a roadway. § 17.148 (definitions).
• Compliance backstop: You cannot subdivide or otherwise convey land in a way that reduces required off‑street parking below minimums. § 17.04.050.

Quick-reference standards table (unincorporated areas)

Use-Specific Parking Standards

• Bed & Breakfasts and Residential Transient Rentals (vacation rentals)
  • B&B/ag homestay: 2 spaces for the host residence + 1/guest bedroom.
  • Vacation rentals: 1/bedroom; stacked parking may be allowed for individual vacation rentals but is not appropriate for B&Bs; spaces must be on-site, with a narrow exception in Yosemite West Unit 1 where off-street spaces in ROW/easements may be approved through encroachment process and only along the project frontage. § 17.108.180.
• Special event facilities
  • Minimum: 1 space/4 seats or 1/4 persons based on maximum occupancy. Aisles/layout must meet the dimensional standards cited in the code; parking lots and spaces may be placed within the road easement setback area at event venues. § 17.108.220(C)(5), (C)(7).
• Yosemite West Mixed‑Use (YWMU)
  • Apartments/SFR in YWMU: studios/1BR at 1.5 spaces/unit; 2+BR or SFR at 2 spaces/unit; laundry (not public) 2 spaces/facility; internal driveways and parking for multifamily/commercial must be paved. § 17.106.020.
• Planned/cluster residential developments (PRD)
  • Parking must conform to the multi‑family requirements contained in “Urban Planning and Design Criteria (UPC)” and must break up long rows: no more than six adjoining spaces without intervening landscaping. § 17.108.100 (design criteria referencing § 17.88.040).

Parking Inside Setbacks and Driveways

• Countywide: Driveways and certain appurtenances are allowed in setbacks; the code also contemplates garages, carports, sheltered parking in front yards under specified conditions. Verify yard allowances during design review. § 17.108.130(A)(4).
• In plan-based commercial/industrial districts:
  • CG‑1: No parking or development inside the minimum project perimeter setbacks except for wells/utilities and “parking within setback areas contiguous to public road.” § 17.88.030(D).
  • CG‑2 and M‑2: Both reference the CG‑1 setback and parking-in‑setback rules. § 17.92.030; § 17.104.030.

District-by-District Notes (where parking rules differ or are clarified)

• CG‑1 — General Commercial Zone‑1

  • Purpose/uses: Commercial centers under an approved “CG‑1 plan.”
  • Parking: Must conform to the commercial parking requirements in the “Urban Planning and Design Criteria (UPC)” (an external, plan-based standard). Also requires breaking long rows with landscaping: no more than six adjoining spaces without landscaping. § 17.88.040(C).
  • Setbacks: Perimeter setbacks are deep; very limited allowances for parking within setbacks as noted above. § 17.88.030(D).

• CG‑2 — General Commercial Zone‑2

  • Purpose/uses: Companion commercial plan district.
  • Parking/design: Uses the same setback and design criteria as CG‑1, including UPC parking and six‑space landscaping breaks. § 17.92.030; § 17.92.040.

• CR — Resort Commercial Zone

  • Purpose/uses: Highway-related/tourist services.
  • Parking: The countywide default standard explicitly does not apply here, meaning CR relies on its own plan/design criteria. Specific CR parking ratios or design rules were not provided in the retrieved materials. Not found in retrieved materials (verify with the jurisdiction). § 17.108.120.

• M‑1 — Light Manufacturing & Industrial‑1

  • Purpose/uses: Light industrial uses. § 17.100.010.
  • Parking: The countywide default standard does not apply in M‑1; district‑specific parking/design criteria were not included in the retrieved materials. Not found in retrieved materials (verify with the jurisdiction). § 17.108.120.

• M‑2 — Heavy Manufacturing & Industrial‑2

  • Purpose/uses: Heavy industrial plan district.
  • Parking/design: Follows the CG‑1 rules for minimum setbacks, parking in setbacks, and design criteria. § 17.104.030; § 17.104.040.

• YWMU — Yosemite West Mixed‑Use Zone

  • Purpose/uses: Supports vacation‑rental sector logistics and limited housing/services in Yosemite West. § 17.106.010–.020.
  • Parking: Specific, numeric requirements apply (see Use‑Specific). § 17.106.020.

• RRZ, MHZ, MTZ, MGZ, GFZ, MPZ, AEZ, TEZ, IMZ, PSZ — Rural/Resource Base Zones

  • Purpose/uses: Rural residential and resource uses; many list churches as conditional uses, with church parking referenced to the off‑street parking standard’s church subsection. In these zones, parking defaults to § 17.108.120 unless a plan district overrides it. See zone texts noting church parking cross-references to § 17.108.120(F) (specific church standards were not retrieved): MHZ, MTZ, MGZ, GFZ.

Bicycle Parking

• Not found in retrieved materials. No bicycle parking requirements were identified in Title 17 excerpts provided. Verify with the County if a separate standard applies.

Loading and On‑Site Circulation

• Site plans for commercial/industrial/multifamily must show on-site parking layout, number of spaces, circulation, and loading areas; these elements are reviewed as part of the standard site plan process. § 17.08.150.
• The code recognizes loading and unloading facilities and on‑site parking among permitted accessory/site functions. § 17.108.060.

Intersections with Other Local Processes

• Landscaping in parking areas: Where the ordinance adopts the UPC standard (e.g., CG‑1, CG‑2, PRD), you must provide landscaping breaks at least every six adjoining stalls. Coordinate with Landscaping and Screening. § 17.88.040(C); § 17.108.100.
• Signage near parking (wayfinding/event signs) must meet the County’s sign standards; special event facilities must comply with the signs chapter. See Signage; § 17.108.190 is referenced for events. § 17.108.220(C)(9).
• Overlay districts (e.g., Design Review, Historic): Parking placement, screening, or materials may be conditioned during Design Review or in certain overlay districts. Not found in retrieved materials for overlay‑specific parking rules; verify case-by-case.

State Law Considerations (ADUs and Accessibility)

• ADU parking is largely preempted by state law. In many circumstances, a local agency may not require parking for ADUs; use the County’s general residential standard only where state law allows. See California ADU law; the 2025 ADU handbook notes multiple parking prohibitions that local agencies must honor. (Gov. Code § 66322)
• Accessible parking design (stall dimensions, signage, access aisles) is set by the California Building Standards Code, not zoning. Special event facilities explicitly require compliance with California Building Code accessibility. § 17.108.220(C)(13).

Checklist

• Confirm your zoning district and whether you are in CG‑1, CG‑2, CR, M‑1, or M‑2 (these use plan/external standards) using the zoning overview. § 17.108.120.
• Calculate parking using the correct ratio and space size (10' x 20'); add 1/employee where required. § 17.108.120.
• Check use-specific rules if you are a B&B, vacation rental, special event facility, PRD, or in YWMU. § 17.108.180; § 17.108.220; § 17.106.020; § 17.108.100.
• Verify setback allowances for driveways and any sheltered parking; in plan districts confirm whether parking may be in setback areas. § 17.108.130; § 17.88.030(D).
• Prepare a site plan that shows stalls, dimensions, circulation, and any loading areas. § 17.08.150.
• If in a design/overlay area, coordinate with Design Review and applicable Overlay Districts. Not found in retrieved materials (verify with the jurisdiction).

Risks & Ambiguities

Plain-English Summary

For most projects in unincorporated Mariposa County, figure two parking spots per home, 1 per 300 sq ft for shops, 1 per 1,000 sq ft for warehouses, plus a space for each employee; each stall is 10 by 20 feet. If you’re in a plan-based commercial/industrial zone (CG‑1/CG‑2/CR/M‑1/M‑2), or you’re a vacation rental, B&B, special event venue, PRD, or in Yosemite West Mixed‑Use, your parking is set by the specific district/use rules—confirm those early in your site plan.
