Alpine County — Design Review

Last reviewed: July 6, 2026

Overview

In the unincorporated areas of Alpine County, “design review” is centered on the combined overlay for the Markleeville Historic District and, separately, countywide scenic corridor protections. The Markleeville Historic District overlay requires review of exterior work to keep new and existing buildings compatible with the area’s historic period of architecture (roughly 1850–1940) under Chapter 18.56 of the zoning ordinance (§ 18.56.010; § 18.56.060) . The zoning ordinance applies only in unincorporated Alpine County (§ 18.04.040) .

The single biggest rule: if you’re doing exterior work in the Markleeville townsite—new construction, additions, demolition of pre‑1940 elements, signs, fences, colors in the commercial core, lighting, grading, or new driveways—plan on a design review before you pull other permits (§ 18.56.020(C)) .

Linking context:

• Get oriented with the county’s zoning & planning overview and base zoning.
• Dimensional rules referenced by design review live in development standards.
• Design overlays are summarized under overlay districts and historic preservation.
• Sign, parking, and variance questions often come up alongside design review; see signage, parking, and variances and exceptions.

Design Review Geographies (Overlays)

MHD Markleeville Historic District Combined Zone

• Purpose. Protect and enhance historic character central to tourism and community identity; ensure new development is compatible with the townsite’s 1850–1940 architectural character (§ 18.56.010; § 18.56.060) .
• Where it applies. The entire Markleeville townsite—about 160 acres as shown on the “Map Showing Markleeville Townsite… dated May 6, 1910” (§ 18.56.020(A)) .
• Typical permitted uses. Same as the underlying base zone; the overlay does not change what uses are allowed (§ 18.56.040) .
• Key dimensional standards. Height, lot area, and setbacks follow the underlying base zone unless the formally adopted Markleeville Historic Design Guidelines establish a more restrictive requirement (§ 18.56.050; § 18.56.070) .
• What triggers design review. Exterior modifications needing a building permit; demolition/removal of any structure or portion built before 1940; any new structure or addition; any sign requiring a sign permit (see Chapter 18.74); outdoor lighting; exterior color changes in the commercial core; grading/terracing; fences/walls; vehicle parking areas/driveways; certain small sheds in the commercial core (§ 18.56.020(B)) .
• Exceptions. Routine maintenance and repairs that don’t change exterior appearance; removal of structures unsafe to occupy due to disaster or dilapidation, upon building department removal permit (§ 18.56.030) .
• Who reviews. The Markleeville Design Review Committee (five regular members plus a museum director ex officio) in a noticed public meeting (§ 18.56.080; § 18.56.090(C)–(D)) .
• Process and timing. Design review starts when Planning is notified of a complete building permit application or a non‑permit activity is proposed; fees may apply. The committee decides within 30 days of the first review meeting; written determinations and any conditions are issued; work cannot start during the appeal period (§ 18.56.090(A)–(E)) .
• Appeals and enforcement. Any interested party may appeal to the Planning Commission within 10 days; failure to comply can trigger fines up to $10,000 per occurrence and a lien (§ 18.56.110; § 18.56.120) .
• Demolition. Demolition/removal of any pre‑1940 structure is not authorized unless a replacement plan is approved (e.g., building permit, CUP with no structures, or a PD development plan per § 18.28.010(B)) (§ 18.56.100) .

Scenic Highway Corridor (Countywide Overlay)

• Purpose. Implement General Plan aesthetics and protect outstanding scenic resources (§ 18.60.010) .
• Where it applies. Any area visible from designated scenic highway corridors identified in the General Plan (§ 18.60.020) .
• Standards. The chapter includes prohibited activities and design guidelines (§ 18.60.030; § 18.60.040). Not found in retrieved materials for their specific lists or criteria—verify with the jurisdiction.
• Interaction with other reviews. These scenic requirements apply in addition to base zoning and any MHD review, where both overlays overlap (§ 18.60.020) .

How the Markleeville Design Review Process Works (Step‑by‑Step)

• File/notify. Planning is notified by the Building Official (for building‑permit work) or by the proponent (for non‑permit activities) to start review (§ 18.56.090(A)) .
• Pay fee. The Board of Supervisors may set a review fee by separate resolution (§ 18.56.090(B)) .
• Public notice. The agenda is posted in two or more Markleeville locations; owners within 300 feet get mailed notice at least 15 business days before the meeting (§ 18.56.090(D)(1)–(2)) .
• Committee meeting. A quorum must be physically present; the committee reviews for consistency with Chapter 18.56 and the adopted Markleeville Historic Design Guidelines (§ 18.56.090(C)) .
• Determination. Within 30 days of the first review meeting, the committee issues a written determination (with conditions if needed) and delivers it to the Building Official within three business days; activity cannot commence during the appeal period (§ 18.56.090(E)) .
• Appeal. Ten days to appeal to the Planning Commission (§ 18.56.110) .
• Enforcement. No building permit or activity may proceed unless compliant; violations may be fined up to $10,000 per occurrence and recorded as a lien (§ 18.56.120) .

Triggers and Exemptions (Markleeville Townsite)

• Triggers (design review required).
  • Exterior modifications requiring a building permit; new construction/additions; demolition/removal of any pre‑1940 structure; signs that need permits; outdoor lighting; exterior color changes in the commercial core; grading/terracing; fences/walls; parking areas and driveways; certain small sheds in the commercial core (§ 18.56.020(B)) .
• Exemptions. Routine maintenance/repair not altering exterior appearance; disaster‑ or dilapidation‑related removals deemed unsafe and permitted for removal by the Building Department (§ 18.56.030) .

Key Standards and References (At‑a‑Glance)

Interplay With Other Alpine County Codes

• Underlying zones control uses and core dimensional metrics; the MHD overlay only narrows design choices and can impose stricter dimensional standards via its adopted guidelines (§ 18.56.040–.050; § 18.56.070) . Check your parcel’s base zone first on the zoning map.
• If your work includes a sign, confirm it meets the sign chapter; many signs in the townsite will need both a sign permit and design review (§ 18.56.020(B)(4))—see signage for content and size rules .
• Any new or reconfigured parking must meet countywide parking standards in addition to design compatibility—see parking and § 18.68.100 .
• If strict application of a standard creates hardship, you may seek relief under variances and exceptions; appeals from MHD decisions go to the Planning Commission (§ 18.56.110) .
• Planned Development projects have their own development plan process (with architectural/site content) and are referenced in the MHD demolition replacement pathways (§ 18.56.100; § 18.28.040–.050) .
• Building‑code compliance is separate; if you see references to the state code, that means the California Building Standards Code governs construction methods, not design compatibility. Not found in retrieved materials for any Alpine County design review adopting Title 24 criteria directly—design review remains a zoning function.

Checklist

• Confirm your parcel is in unincorporated Alpine County (§ 18.04.040) .
• Verify whether your site lies within the Markleeville townsite boundary (§ 18.56.020(A)) .
• Identify if your activity triggers review (work types listed in § 18.56.020(B)) .
• Check the underlying base zone’s dimensional rules and any stricter MHD guideline standard (§ 18.56.050–.070) .
• Prepare materials sufficient for committee review (plans, elevations, colors, lighting, site work) in line with the adopted Markleeville Historic Design Guidelines (§ 18.56.090(C)) .
• Coordinate public noticing timelines (agenda posting; 300‑ft mailed notices 15 business days before meeting) (§ 18.56.090(D)) .
• Allow for the 30‑day committee decision window and the appeal period before starting work (§ 18.56.090(E); § 18.56.110) .
• If demolishing any pre‑1940 structure, line up an approvable replacement plan (permit, CUP, or PD plan) (§ 18.56.100) .
• If your project is visible from a designated scenic corridor, incorporate applicable scenic guidelines (§ 18.60.010–.020) .

Risks & Ambiguities

Plain-English Summary

If you’re doing exterior work in the Markleeville townsite, expect a public design review to make sure your project fits the community’s historic look. The committee can condition approvals, you have a 10‑day appeal window, and demolition of anything from before 1940 requires an approved replacement plan. Outside Markleeville, scenic‑corridor areas also carry design expectations if the project is visible from designated highways.
