Sand City — Historic Preservation

Last reviewed: July 2, 2026

Overview

Sand City’s zoning ordinance does not establish a full, standalone local historic-preservation program (no local “landmark” or Mills Act chapter was located in the retrieved ordinance). Historic-resource protections in Sand City appear as targeted rules inside other chapters: the Design Control (DC) overlay, coastal zone rules, the ADU chapter (special parking rules where a dwelling is inside an historic area), and the floodplain/exceptions rules that treat “historic structure” as a special category. To find which approvals will apply to a given property, start with the property’s zone and whether it lies inside the DC or any CZ overlay, then check the floodplain/historic exceptions and the ADU rules. See the City’s base zoning overview for map/context via the Sand City Zoning page.

How the ordinance treats historic resources (core rules)

• Definition — "Historic structure." Sand City adopts a standard regulatory definition that uses National/State/local register criteria: a “historic structure” is one on (or eligible for) the National Register, a contributing property to a National Register district, listed on a State inventory, or on a local inventory recognized by an approved state program. This is the controlling definition used when the code carves out special treatment (e.g., flood-plain exceptions). § 18.88.010.

• Design control (DC) overlay. Where the DC overlay applies, exterior changes, signs, fences, and additions require a design permit and committee review; the DC overlay is the primary local mechanism where architecture and visual character (including potential impacts to historic resources) are reviewed. See § 18.58.010 (purpose), § 18.58.030 (design permit required for uses in DC), and § 18.58.040 (design committee composition). § 18.58.050 addresses coastal-zone design control.

• Coastal zone overlays (CZ) and coastal-specific districts. Coastal overlay chapters (for example CZ and related coastal-use districts such as CZ HP habitat preserve) add permit layers and coastal-development permit triggers; where a property sits inside a coastal overlay, historic-resource issues are evaluated under both the local ordinance and the Local Coastal Program. The CZ overlay and coastal district rules are in § 18.50.010 and related CZ chapters.

• Floodplain exceptions for historic structures. Floodplain variance/exception rules explicitly authorize exceptions for the repair or rehabilitation of a “historic structure” if the work will not preclude its continued designation and the exception is the minimum necessary to preserve the historic character. See the flood/exceptions chapter: § 18.88.130(D)(2) and the historic-structure definition in § 18.88.010.

• Accessory Dwelling Units (ADUs) — parking exception for historic areas. The ADU chapter exempts ADUs from required additional parking in specific circumstances; one listed exemption is when the ADU is located inside an architecturally significant historic district (the ordinance’s ADU parking exceptions list appears at § 18.63.050(B)(6)(d) and related junior ADU standards are § 18.63.060). That means ADU parking requirements are relaxed where a property is in such a historic district. § 18.63.050 / § 18.63.060.

• Design review & site-plan requirements in zones where historic issues commonly arise. Several districts that allow residential or mixed-use development (for example MU‑P, R‑3) require site plan approval and design-review regulations; projects in those zones will be subject to DC/design-review where the overlay applies. See district rules (e.g., § 18.13.060 for MU‑P, § 18.12.060 for R‑3) and the general design-control chapter § 18.58.

• What the ordinance does not show in the retrieved materials: a local landmarks register, a Mills Act program, a formal local historic‑preservation commission, or a local ordinance describing a process to designate local historic landmarks/districts. Not found in retrieved materials.

District-by-district breakdown (where historic rules intersect zoning)

Below are the Sand City districts where the code explicitly brings historic-preservation effects into permitting or standards. Each subsection lists the district purpose, typical review triggers affecting historic resources, key dimensional / process standards that matter for preservation decisions, and where the district typically applies.

DC (Design Control) district

• Purpose: The DC overlay exists to "set standards intended to achieve desired results in housing, commercial and industrial development" and to review external design, signs, fences, and site appearance. § 18.58.010.
• Typical permitted uses / triggers: All proposed uses in the DC require a design permit (i.e., design review) — exterior alterations, signs, and additions are subject to DC. § 18.58.030.
• Key standards / process: Applications must include elevations, color schemes, landscaping, and other visual information. A five‑member design committee reviews applications; the Planning Director is ex‑officio. § 18.58.020–040.
• Where it applies: The DC is an overlay (see the combining districts list) and is applied in combination with base zones on the zoning map. § 18.06.020.

CZ (Coastal Zone) overlay and coastal-zone districts (including CZ HP)

• Purpose: The CZ overlay enforces consistency with the Local Coastal Program and brings coastal‑permit review to projects in the coastal zone. § 18.50.010.
• Typical triggers affecting historic resources: Coastal development permit requirements, coastal-specific site-plan and environmental review; coastal permits must be shown to conform to the LCP, and the City’s coastal procedures provide public hearing notice and findings requirements. § 18.50.020, § 18.50.050–060.
• Key standards: Coastal districts also include special district standards (e.g., CZ HP for habitat) that can limit changes to site form, views, and siting—these intersect with preservation by constraining alterations and additions near protected resources. § 18.48.010–030.
• Where it applies: Properties inside the mapped coastal overlay on the zoning map (see § 18.06.060 adoption of zoning map).

R‑1 / R‑2 / R‑3 (Residential districts) — ADU and site review intersections

• Purpose: Standard residential districts; ADU rules and design control requirements interact with historic considerations. § 18.06.010, the ADU chapter § 18.63.
• Typical triggers: ADU applications (ministerial) and junior ADUs; where the property is in an "architecturally significant historic district" ADU parking exceptions apply (see § 18.63.050(B)(6)(d)). § 18.63.050.
• Key dimensional/process standards that matter: ADU setbacks, parking limits, and ministerial approval timelines; junior ADUs permitted ministerially when standards met (§ 18.63.060). § 18.63.050–060.
• Where it applies: Across the R‑1/R‑2/R‑3 zones per the ADU chapter; design review or site plan may still be required where DC overlay or district rules call for it.

MU‑P (Planned Mixed‑Use) and other zones with site‑plan / design‑review requirements

• Purpose: Mixed-use and employment-focused zone; site plan approval is mandatory for most physical alterations and design-review rules apply. § 18.13.060.
• Typical triggers: Site-plan approval by City Council; design review; PUD requirements where large projects are proposed. § 18.13.060.
• Key standards: On-site parking, landscaping, and design-review conditions apply and may require architectural or landscape treatments to avoid adverse impacts on nearby historic resources. § 18.13.050–060.

Decision‑relevant summary table

Checklist — what an applicant must satisfy (historic‑resource projects)

• Determine whether the property is inside the DC overlay or any CZ overlay and consult the zoning map. Verify base zoning (R‑1, R‑2, R‑3, MU‑P, etc.). § 18.06.010–060.
• If in DC, prepare design permit application with front/side/rear elevations, color/materials, landscaping, sign plans and other visuals as required. § 18.58.020–030.
• If the property lies in the coastal zone, include LCP analysis and be prepared for coastal development permit procedures and notices. § 18.50.050–060.
• If the building is an identified historic structure, submit documentation of the listing/eligibility and, for floodplain variance requests, justify that proposed work will not preclude designation and that the exception is the minimum necessary. § 18.88.010, § 18.88.130(D)(2).
• For ADUs, check § 18.63 parking and setback exceptions and record any deed restriction required by junior ADU standards. § 18.63.050–060.
• Submit any required site plan, PUD or conditional-use materials if the base district requires site-plan approval (MU‑P, R‑3, etc.). § 18.13.060, § 18.12.060.

Risks & Ambiguities

Plain‑English Summary

Sand City does not have a full local historic‑preservation code chapter in the retrieved ordinance; instead, historic resources are treated case‑by‑case via the Design Control (DC) overlay, coastal permits, ADU parking exceptions for properties inside “architecturally significant historic districts,” and floodplain exceptions for listed historic structures. That means if your property is in the DC or CZ overlay, expect design review and coastal findings; if it’s a listed historic structure, you get some narrowly tailored exceptions (especially in flood areas). Verify with City planning about any local landmark listings or historic‑district maps because the ordinance text returned did not show a formal local designation procedure.
