Ridgecrest — Historic Preservation

Last reviewed: July 2, 2026

Overview

This page summarizes what the City of Ridgecrest zoning/planning ordinance says about historic preservation (what is regulated in the local zoning code, how historic places can affect land-use review, and where to look in the code). Ridgecrest does not appear to maintain a standalone local historic‑landmark chapter in the materials provided; the code references historic and cultural resources within specific districts, site‑plan and specific‑plan rules, and in environmental/cultural resource mitigation requirements. See the cited local code §§ and the state ADU/building‑code references below for related requirements and exceptions. For the citywide zoning framework see Ridgecrest Zoning.

Key local code references used below: § 106‑308, § 106‑326, § 106‑170—106‑172, § 106‑39, § 106‑209—106‑214, and the Ridgecrest Commercial Specific Plan text (Table/§ 106‑575 references) and its cultural resources mitigation items; supporting state guidance appears in the ADU handbook and the California Building Standards Code.

What Ridgecrest's ordinance actually says (synthesis)

• The code explicitly recognizes the protection/location of areas with scenic, historic or cultural value inside the RSP (Recreation, Schools and Public Use) district; those uses are listed as allowable uses in § 106‑308. This means publicly‑oriented open space, cemetery, park and similar sites with historic/scenic/cultural values are a permitted use in the RSP district.

• The ordinance does not contain an obvious, standalone local historic preservation program (no clear "landmarks" chapter, historic‑district designation procedure, or local historic‑resources commission text was found in the retrieved materials). Where historic resources matter in the code, the treatment is indirect: via specific plan/environmental mitigation measures, site plan and discretionary review, and state law references (see "Information Gaps" below). Not found in retrieved materials.

• Projects that trigger site plan review or discretionary entitlements are subject to a design/development review process that can be used to condition projects where historic resources are present; see § 106‑170—§ 106‑172 for the site plan‑review procedural triggers and required submittal information. These provisions are the standard local vehicle to require compatibility and mitigation for sensitive resources.

• The zoning clearance process requires conformity with the zoning code, general plan and any existing entitlements and permits; zoning clearances are required where no discretionary review applies (§ 106‑39). If there are violations or outstanding entitlements, a zoning clearance can be denied or modified. This is the ministerial gate that still requires consistency with other protections (e.g., cultural resource mitigation in a specific plan).

• The planning commission’s variance and public‑hearing authorities (including the findings necessary to grant variances) are set out in § 106‑209 and § 106‑214; those bodies handle discretionary exceptions where strict application of development standards would cause practical difficulty — this is a path for owners of historic properties to request relief when standards would unreasonably affect preservation.

• The Ridgecrest Commercial Specific Plan contains focused design, landscape, circulation and environmental rules for that plan area (including a table of permitted uses, and cultural‑resource mitigation measures such as stop‑work and archaeological evaluation procedures). Those specific‑plan rules operate as the zoning for the specific plan area and explicitly include cultural resource treatment (e.g., mitigation item E‑1 in the specific plan calls for diversion of construction and archaeological assessment when archaeological resources are discovered). See the specific plan / Table 106‑575 and the cultural resource mitigation items.

• State guidance that affects local practice:

  • ADU rules: State ADU guidance allows local objective standards that can prevent adverse impacts on historic resources and clarifies ADU parking exceptions inside historic districts; local ADU rules should therefore coordinate with historic protections (state ADU guidance cited). The Ridgecrest code excerpts provided do not contain a clearly numbered local historic‑district ADU exception section; rely on state ADU law where local text is silent or absent.
  • California Building Standards Code / Historical Building Code: the state building code includes special variances/allowances for historic structures (e.g., Appendix G G106.3 and the CHBC) which local building officials apply at permit review. These are state building‑code rules, not the Ridgecrest zoning code, but they affect historic structures during the permit/building phase.

Practical reading: Ridgecrest handles historic resources mainly by (1) allowing preservation‑type uses in RSP (§ 106‑308), (2) folding cultural‑resource mitigation into specific plans and the environmental review process (Ridgecrest Commercial Specific Plan), and (3) relying on site‑plan review, discretionary permits and variance findings to require preservation/compatibility measures. Direct local procedures to designate landmarks or to create a local historic register were not located in the retrieved zoning materials.

District-by-district breakdown (where the code mentions historic/cultural matters)

RSP (Recreation, Schools and Public Use) — § 106‑308

• Purpose: intended for open space, public facilities, parks, cemeteries and "areas of scenic, historic and cultural values." § 106‑308 identifies preservation of such areas as a purpose of the district.
• Typical permitted uses: recreation areas, civic centers, parks, playgrounds, cemeteries, fairgrounds and areas of scenic/historic/cultural value; accessory structures incidental to those uses. § 106‑308(b)(1).
• Key dimensional/administrative standards: minimum site area 6,000 sq ft (unless preexisting smaller lot), and yard/site plan review requirements; specific yard/distance standards are determined at site plan review. § 106‑308(d)–(f).
• Where it applies: areas mapped as RSP on the official zoning map; consult the city clerk’s copy of the zone map for parcel application. § 106‑281 (zone map adoption and office of city clerk).

CN (Neighborhood Commercial) — § 106‑326

• Purpose: neighborhood‑scale retail/services for local residents; commercial design standards facilitate compatibility with surrounding neighborhoods. § 106‑326(a).
• Typical permitted uses: retail, restaurants (limited), offices; conditional uses include public/quasi‑public uses and others listed in § 106‑326(b)–(c).
• Key dimensional standards: building height limit 35 ft, minimum lot area 6,000 sq ft, front yard setback 10 ft, minimum lot depth 100 ft; side/rear setbacks vary (see § 106‑326(d)–(g)). These standards are the baseline used in site plan review where design compatibility with historic places could be required.
• Where it applies: parcels designated CN on the zoning maps (see zone map). § 106‑281.

Ridgecrest Commercial Specific Plan (Specific‑plan zoning) — (Table / § 106‑575 references)

• Purpose: the specific plan functions as the zoning for its area and establishes tailored development standards, permitted uses (Table 106‑575(c)‑2), landscaping, circulation and design rules intended to create a unified commercial corridor and protect scenic corridors. The specific plan text calls for architectural unity, landscaping, and visual screening along major corridors.
• Historic/cultural treatment: the specific plan includes cultural resource mitigation commitments (for archaeological finds and burials) and stop‑work/consultation requirements (mitigation items E‑1 and E‑2 in the specific plan EIR text). These are contractually binding on projects within the plan area and are enforced in project review.
• Where it applies: the specific plan area is identified in the Specific Plan (see Figure 1 and the specific plan text that becomes the zoning for that area). § 106‑575 references the permitted‑use table and the specific plan authority.

Note: I did not find a local chapter titled "Historic Preservation," "Landmarks," or a listed process for local historic designation in the retrieved zoning materials. Not found in retrieved materials.

Decision‑relevant quick table

Checklist — what an applicant must satisfy (preliminary)

• Confirm whether the property lies in RSP, CN, or within the Ridgecrest Commercial Specific Plan area on the official zoning map (consult the city clerk / planning). § 106‑281, § 106‑308, § 106‑326.
• Determine whether your project requires site plan review (substantial alterations or new development). If yes, prepare full site‑plan materials per § 106‑170—§ 106‑172.
• If the project is ministerial (no discretionary review) request a zoning clearance and show consistency with zoning, general plan and entitlements (§ 106‑39).
• If archaeological or buried human remains are found, stop work and follow the specific plan/EIR cultural procedures (consult a qualified archaeologist and the State Historic Preservation Office); see the specific plan mitigation items (E‑1, E‑2).
• If strict development standards would harm historic fabric, evaluate variance relief with the planning commission; prepare findings to meet § 106‑214.
• Coordinate building permits with the local building official; where the structure qualifies as historic, state building‑code alternatives/variance provisions may apply (CBC/CHBC).
• If proposing an ADU on a property with historic concerns, confirm any local ADU objective standards (state ADU guidance is permissive but local text must be checked). Local ADU/historic cross‑references were not located with a section number in the retrieved materials. Verify with staff. Not found in retrieved materials; see state ADU guidance.

Also: review related local pages about parking, design review, and development standards for objective rules that will be applied during review (parking exceptions for historic areas may be governed by state ADU law). For local rules on these topics see the city menu pages on parking, development standards, and design review. (See the internal links embedded on this page.)

Risks & Ambiguities

Plain‑English Summary

Ridgecrest’s zoning code does not show a dedicated local historic‑preservation ordinance in the materials provided; instead, historic resources are protected where they appear in the zoning map/specific plans and through the city’s site‑plan, conditional‑use, variance, and environmental review processes (notably § 106‑308 for RSP uses and the Ridgecrest Commercial Specific Plan cultural provisions). If you own or propose changes to a potentially historic property, expect site‑plan/discretionary review and coordinate early with planning and building staff.
