Alpine County — Parking

Last reviewed: July 6, 2026

Overview

This page explains how off-street parking is regulated by the Zoning Ordinance of the County of Alpine for projects in the unincorporated areas. The core rules live in Title 18 (Zoning), primarily in the countywide standards of Chapter 18.68 and the definition section of Chapter 18.08. Every project should start by confirming its base zoning under the county’s Alpine County Zoning map and then apply the countywide parking ratios and siting limits below.

Plain-English keystone: Off-street parking is required for every land use in unincorporated Alpine County per § 18.68.100, with ratios by use, minimum stall size of 9 ft by 18 ft by 7 ft high, rounding up to the next whole space, and restrictions on putting spaces in required front/side yards and at street corners.

• Applicability reminder: All Title 18 standards apply in the unincorporated areas only (§ 18.04.040).
• Countywide parking rules apply together with your base district standards and any combined/overlay district rules; where a district or overlay is silent, Chapter 18.68 controls (§ 18.68.010).

Countywide parking standards you will use on most projects

• Required across all zones with use-by-use ratios in § 18.68.100. Fractions round up. Spaces are prohibited within one-half of the required yard area nearest the front/side street line of any required front yard, and within the sight-distance area of a street corner unless a variance is approved.
• A standard parking space is at least 9 ft wide by 18 ft long with 7 ft vertical clearance (§ 18.08.610).
• If a use is not listed, the Planning Commission sets the requirement (§ 18.68.100(D)). Off-site parking may be allowed on adjacent or noncontiguous parcels with a use permit (§ 18.68.100(E)).

Core off-street parking ratios (selected)

Secondary dwelling units (local “second-family dwellings”)

• Countywide ratio: see table above (§ 18.68.100(A)(2)).
• Placement and tandem rules: Required spaces must be on the same lot, not in the public right‑of‑way; these spaces cannot be located in tandem with the minimum spaces required for the primary unit, though the secondary-unit’s own spaces may be tandem (§ 18.69.030(D)). Verify any updates relative to current California ADU law.

Siting and yard protections that often trip projects

• Do not place required stalls within the “front half” of any required front yard, or within a required street-side yard on a corner lot. Avoid the corner sight-distance area unless a variance is granted (§ 18.68.100). Consider Alpine County Variances and Exceptions if needed.

Plan-level loading information

• For Planned Development (PD) projects, your development plan must map the “location, arrangement and dimensions of truck loading spaces and docks,” along with the number/dimensions of parking spaces, aisles and angles (§ 18.28.030(C)(4)).

How parking interacts with Alpine County districts and overlays

Use-specific parking ratios above apply countywide (§ 18.68.100). Several districts and combined/overlay districts either restate that Chapter 18.68 controls parking, or specify how parking appears in their site-layout rules. The notes below emphasize purpose, typical uses, key dimensional standards, and any parking tie-ins.

AP — Agricultural Preserve

• Purpose/uses: Agricultural preserve lands; other regulations section ties AP uses to Chapter 18.68 for off-street parking.
• Parking: Must comply with countywide standards in § 18.68.100.
• Key standards: Not found in retrieved materials.

LP — Land Preserve

• Purpose/uses: Preserve natural/open space, allow limited resource-based activities (permitted and conditional uses listed).
• Parking: Countywide standards apply (§ 18.68.100).
• Key standards: Not found in retrieved materials.

NC — Neighborhood Commercial

• Purpose/uses: Neighborhood-scale retail and services; typical uses in § 18.40.020 (not retrieved in full). Key lot/yard standards include 10,000 sf minimum lot area; 30 ft front and rear yards; side yards vary near residential (§ 18.40.040). A main building is limited to 2,500 sf floor area (§ 18.40.050). Height per § 18.68.050 (§ 18.40.060).
• Parking: Off-street parking and loading allowed outside the building; countywide parking rules of Chapter 18.68 expressly apply (§ 18.40.070).

C — Commercial

• Purpose/uses: Business centers (retail, offices, hotels/motels, etc.). Height limit 3 stories/45 ft (§ 18.44.050). Yard minimums: Front 6 ft; sides/rear vary when abutting residential (§ 18.44.060).
• Parking: “Off-street parking and other requirements are set forth in Chapter 18.68” (§ 18.44.070), so apply the countywide ratios in § 18.68.100.

IND — Industrial

• Purpose/uses: Broad industrial and commercial uses. District text is in Chapter 18.48 (purposes and use lists retrieved).
• Parking: Apply countywide standards in § 18.68.100. District-specific numeric parking/loading standards: Not found in retrieved materials.

INS — Public/Institutional

• Purpose/uses: Public/quasi-public facilities; yard minimums include Front 30 ft; Sides 20 ft; Rear 20 ft (§ 18.52.040).
• Parking: Off-street parking requirements are set forth in Chapter 18.68 (§ 18.52.060).

PD — Planned Development (overlay-type zone)

• Purpose: Enable comprehensive, clustered development with open space protection.
• Parking/loading: PD plans must show parking counts/dimensions, aisle widths, bay widths, angles, and truck loading spaces/docks (§ 18.28.030(C)(4)). Height/yard standards may deviate if the total development is improved (§ 18.28.050).

—CR — Commercial Recreation (combined overlay)

• Purpose/uses: Recreation-serving retail and facilities; when combined with a base zone, the more restrictive rules govern. Chapter 18.68 applies to all such combined districts (§§ 18.64.020–.050).
• Parking: Use countywide standards (§ 18.68.100).

MHD — Markleeville Historic District (combined overlay)

• Purpose: Protect and enhance historic character of Markleeville townsite with added design guidance and review (§ 18.56.010).
• Parking: No unique parking ratios were retrieved; apply countywide standards in § 18.68.100 and expect design sensitivities via Alpine County Design Review within the overlay.

Bear Valley Area parking mitigation (fees for secondary units)

• A county program imposes a “Bear Valley Future Parking Needs Mitigation Fee” of $1,800 per secondary dwelling unit within the Bear Valley Area when such a unit is approved (§ 18.87.020).

What’s not in Title 18 (zoning) but commonly confused with it

• Bicycle parking: Not found in retrieved zoning materials. State building standards (CALGreen) may impose bicycle parking for certain projects; those are outside zoning and governed under the California Building Standards Code. Not found in retrieved materials.
• Accessible parking (number/markings, etc.): Governed by state accessibility standards under the California Building Standards Code. Not found in retrieved materials.

For parcel-specific questions that hinge on overlays or design treatments, also check Alpine County Overlay Districts, Alpine County Development Standards, and Alpine County Historic Preservation.

Checklist

• Confirm your site’s base zoning and any combined/overlay zones under Alpine County Zoning.
• Calculate spaces per § 18.68.100; round up. Cite your use category precisely.
• Dimension stalls to at least 9 ft x 18 ft x 7 ft clear; show drive aisles and angles if using angled parking (§ 18.08.610; § 18.28.030(C)(4) for PD).
• Keep required stalls out of required front/street-side yards and corner sight-distance areas unless a variance is granted (§ 18.68.100; see Alpine County Variances and Exceptions).
• If use is not listed, request a Planning Commission determination under § 18.68.100(D).
• If proposing off-site parking, secure a use permit per § 18.68.100(E).
• For secondary units, follow § 18.69.030(D) siting/tandem rules and § 18.68.100(A)(2) ratios; in Bear Valley, add the parking mitigation fee (§ 18.87.020). Verify any state ADU preemption against local rules via California ADU law.
• In overlays like MHD or PD, coordinate with Alpine County Design Review for layout and context consistency (§ 18.28.030; § 18.56.010).

Plain-English Summary

If you’re building or changing a use in unincorporated Alpine County, plan for off-street parking. Count spaces using the county’s chart in § 18.68.100, round up, size each stall at least 9 by 18 feet, and keep required stalls out of required front yards and corner sight lines. Special districts and overlays still rely on the same countywide parking rules, though PDs must show loading spaces on their site plans; secondary units have extra placement rules and, in Bear Valley, a set parking fee.
