Calaveras County — Design Review

Last reviewed: July 6, 2026

Overview

In unincorporated areas of Calaveras County, “design review” is a discretionary check on architecture, site layout, materials, landscaping, and related features—used only where the County has mapped a Design Review overlay. The rules live in Title 17 of the County Zoning Code and apply alongside base zoning and other development standards. This page explains when design review applies, what gets evaluated, and how it is processed under the County’s ordinance.

Key rule: Design Review is required only on parcels mapped with the Design Review (DR) Overlay; it does not apply Countywide and does not change your base zoning uses or dimensional standards (§ 17.29.020; § 17.11.010–.030).

Where Design Review applies (DR Overlay)

• The County identifies specific areas where design review is mandatory by applying a Design Review (DR) Overlay to the Official Zoning Map, shown with a “-DR” suffix added to the base zone (for example, C-1-DR) per § 17.11.030.
• The overlay includes prescribed areas of Mokelumne Hill and any other areas adopted by the Board of Supervisors with community input, per § 17.11.020.
• Outside mapped DR areas, projects are not subject to the County’s design review procedure (§ 17.29.020).

See the County’s overlay districts overview for how overlays interact with base zoning.

How Design Review works

• Review authority. The Planning Commission conducts Design Review for projects already requiring Commission-level approval; otherwise, the Planning Director is the review authority (§ 17.29.030; § 17.26.030(C)).
• Applications. File on prescribed forms; if your project also needs a Use Permit or Variance, Design Review is processed concurrently (§ 17.29.040.A–B).
• Public notice and hearings. All Design Review applications require public notice under § 17.27.070. A public hearing is required when the Planning Commission is the review authority; no hearing is required when the Director is the review authority (§ 17.29.040.C–D).
• Scope of review. The County considers the site plan, building proportions/massing/details, orientation and relationship to surroundings, on‑site parking layout, exterior materials, fencing/walls/screening, landscaping and hardscape, and all signs including size, lighting, color, and materials (§ 17.29.050.A(1)–(7)).
  • Parking layout reviewed in Design Review must also meet separate parking standards (e.g., design standards in § 17.22.080) (§ 17.29.050.A(3)).
  • Landscaping and sign details are part of Design Review; substantive sign rules are addressed separately under County signage regulations (§ 17.29.050.A(6)–(7)).
• Decisions, appeals, expiration. Appeals follow § 17.27.140; approvals become effective/expire per § 17.27.110; approvals may be revoked per § 17.27.130 (§ 17.29.060).
• Zoning clearance tie‑in. Before permits issue, staff verifies conformance with any applicable Design Review approval (§ 17.28.040).

For background on common procedures, see the County’s zoning & planning overview.

District-by-district: Design Review areas

Design Review is mapped as an overlay and does not change base zoning allowed uses or base dimensional standards (setbacks, height, etc.). Where the DR overlay applies, the following subareas are identified in the code.

Design Review (DR) Overlay Zone

• Purpose: Identify areas where Design Review is required and guide development consistent with adopted standards and the General Plan (§ 17.11.010; § 17.29.010).
• Typical permitted uses: Not altered by the overlay. Uses remain those allowed by the underlying base zone (Not found in retrieved materials for any DR-specific use list).
• Key dimensional standards: Not altered by the overlay; base zoning controls (Not found in retrieved materials for DR-specific setbacks/height).
• Where it applies: Any parcel shown with “-DR” on the Official Zoning Map (§ 17.11.030).

Mokelumne Hill DR Area

• Purpose: Apply adopted design review standards specific to prescribed areas of Mokelumne Hill (§ 17.11.020(A)).
• Typical permitted uses: Not changed by DR; base zoning controls (Not found in retrieved materials for DR-specific use list).
• Key dimensional standards: Not changed by DR; base zoning controls (Not found in retrieved materials for DR-specific standards).
• Where it applies: Prescribed mapped areas of Mokelumne Hill (§ 17.11.020(A)).

Other Board‑Adopted DR Areas

• Purpose: Establish DR with community‑adopted standards in other locations as designated by the Board of Supervisors (§ 17.11.020(B)).
• Typical permitted uses: Not changed by DR overlay (Not found in retrieved materials for DR-specific use list).
• Key dimensional standards: Not changed by DR overlay (Not found in retrieved materials for DR-specific standards).
• Where it applies: Any additional areas mapped by Board action with the “-DR” suffix (§ 17.11.030).

What Design Review evaluates (submittal focus)

When you apply, be prepared to show:

• Site plan showing building placement, orientation, on‑site circulation, and parking arrangement consistent with both DR criteria and applicable parking standards (§ 17.29.050.A(2)–(3)).
• Architectural elevations with massing, proportions, roof forms, materials, and details (§ 17.29.050.A(1), (4)).
• Fencing, walls, screening, and; if applicable, landscape and hardscape plans (§ 17.29.050.A(5)–(6)).
• Sign plan with size, location, color, materials, and lighting (§ 17.29.050.A(7)).

Also coordinate with any separate approvals affecting historic resources in mapped areas; limited‑scope approvals for historic demolition run under § 17.16.060 (separate from DR).
Do not confuse design review with the California Building Standards Code; building code reviews address construction methods and safety, not the discretionary design topics listed above.

Calaveras County Design Review at a Glance

Checklist

• Confirm the parcel is in a -DR overlay on the County Zoning Map (§ 17.11.030).
• Identify whether the project already needs Commission‑level approval (which sets the DR review body) (§ 17.29.030).
• Prepare submittals: site plan, elevations, materials, fencing/screening, landscaping/hardscape, and sign plan as applicable (§ 17.29.050.A).
• Coordinate any required Use Permit/Variance so DR can be processed concurrently (§ 17.29.040.B).
• Ensure your parking layout meets parking design standards in addition to DR criteria (§ 17.22.080; § 17.29.050.A(3)).
• Anticipate public notice and, if Commission‑level, a public hearing (§ 17.29.040.C–D).
• Track appeal windows and approval expiration per common procedures (§ 17.29.060; § 17.27.110).

Risks & Ambiguities

Information Gaps

• The specific, adopted design standards for Mokelumne Hill and any other DR‑mapped neighborhoods were referenced but not included in the retrieved materials.
• The Official Zoning Map layers and precise boundaries of each -DR area were not included in the retrieved materials.
• Any DR‑specific objective dimensional standards (if any exist) were not found in the retrieved materials; base zoning appears to control.

Plain-English Summary

If your project is in unincorporated Calaveras County and your parcel has a “-DR” overlay, the County will review your building design, site layout, landscaping, parking arrangement, and signs for compatibility with adopted design standards. The Planning Director handles most reviews, but Commission‑level projects go to a public hearing. Design review doesn’t change what you can build under your base zoning—it ensures it looks and fits in appropriately.
