Cloverdale — Overlay Districts

Last reviewed: July 1, 2026

Overview

Cloverdale’s Title 18 zoning code does not define a formal “overlay district” or “combining district” labeling system in the retrieved ordinance materials. Instead, the city uses several district tools and special-district processes — Planned Unit Development (P-D), Specific Plan (SP), PUD permit modifications, historic design review, conditional use permits, and map/amendment procedures — to achieve the same on‑the‑ground effect that an overlay district would (site‑specific modifications layered over a base zone). See § 18.01.060, § 18.03.080, § 18.08.020, and § 18.08.030 for the controlling procedures and authorities.

Note: Because the code does not contain a labeled “overlay” or “combining” chapter in the retrieved materials, this page explains how Cloverdale accomplishes overlay‑like regulation and then provides a district‑by‑district breakdown of the actual base zones that would most commonly be affected. Verify parcel‑specific questions with the city. Not found in retrieved materials: any section titled “Overlay District” or “Combining District.”

How Cloverdale handles overlay‑type controls (legal mechanisms)

• Zoning map amendments and creation of special, site‑specific controls occur through the amendment process and ordinance adoption; the rules and findings are in § 18.03.080. This is the formal way to create any map‑level change (including a site‑specific zone or specific plan area).
• Planned developments (P‑D) and Specific Plan (SP) districts are the primary tools for area‑specific regulations that modify base zone standards (i.e., they operate like overlays by establishing different standards for a defined area). See § 18.08.020 and § 18.08.030.
• PUD permits and PUD modifications can adjust development standards within certain districts (examples: Downtown Core and Office/Residential provisions) without creating a separate overlay map symbol; see § 18.05.050.
• Conditional use permits and design review are commonly used to impose site‑specific conditions that function like overlay rules (see § 18.03.110 and § 18.03.150). Design review standards (historic and non‑historic) may add or relax dimensional or façade requirements.
• Historic considerations: where the code allows modification of underlying standards for historic properties (e.g., within PUD processes), the code refers to historic evaluation and preservation standards; the O‑R district also carries historic design provisions. See § 18.05.050 and the O‑R notes.

Practical takeaway: In Cloverdale you will not usually find a map symbol called “H‑Overlay” or “F‑Overlay” in the retrieved code; overlay‑style outcomes are implemented by adopting a new zone, SP/P‑D designation, or by discretionary permits that add conditions to the underlying district. Verify parcel‑specific designations with the official zoning map kept by the city clerk and planning director under § 18.01.060.

District‑by‑district breakdown

Below are the base districts in Title 18 that an overlay (or SP/P‑D) would normally modify. For each district I list purpose, typical permitted uses, key dimensional standards, and where the district applies (as stated in the code). For parking, design review, and other implementation details see the linked topics inline.

• Typical permitted uses: standard single family, duplexes, ADUs. § 18.04.040.
• Key dimensional standards: lot area 6,000 sf, front setback 20 ft, building height 35 ft, FAR 0.35–0.40 depending on lot size. § 18.04.050.

R‑3 (Multifamily Residential)

• Purpose: Higher‑density residential (apartments, multifamily). § 18.04.040.
• Typical permitted uses: multifamily units subject to standards and permitting. § 18.04.040.
• Key dimensional standards: minimum lot area 10,000 sf, front setback 20 ft, rear setback varies by height (one‑story 10 ft, two‑story 20 ft), density up to 16 units/net acre. § 18.04.050.

DTC (Downtown Core)

• Purpose: Pedestrian‑oriented downtown core and active ground‑floor commercial. § 18.05.020.
• Typical permitted uses: retail, office, upper‑floor residential (with limitations on street‑front residential on certain corridors). § 18.05.030.
• Key dimensional standards and special rules: Downtown special frontage and design expectations; PUD can modify where appropriate (see § 18.05.050). § 18.05.030, § 18.05.050.
• Where it applies: Downtown segments identified on the zoning map; special street segments are called out in the DTC rules. § 18.05.030.

O‑R (Office/Residential)

• Purpose: Office and low‑intensity mixed uses, often on former residential lots transitioning to office or mixed uses. § 18.05.020.
• Typical permitted uses: offices, compatible residential (including conversions), limited commercial. § 18.05.030.
• Special note: Historic design provisions apply in the O‑R district and single‑family houses in O‑R follow R‑2 standards where specified. § 18.05.030 (notes).

G‑C and S‑C (General Commercial and Service Commercial)

• Purpose: Neighborhood/throughway commercial (G‑C) and higher intensity commercial/service uses (S‑C). § 18.05.020.
• Typical permitted uses: retail, service businesses; more intensive services and light commercial permitted in S‑C. § 18.05.030.
• Dimensional standards: See Table 18.05.040‑A in § 18.05.040 for lot coverage, setbacks and FAR applicable to commercial zones. § 18.05.040.

PI (Public Institutional)

• Purpose: Government, public facilities and related uses. § 18.07.010.
• Typical permitted uses: schools, libraries, community centers, utilities (many require conditional use permit). § 18.07.020.

P‑D (Planned Development) and SP (Specific Plan)

• Purpose: Tools to create project‑specific regulations and modify base standards for a defined area; these are the city’s main mechanism for area‑specific customization (functional equivalent to overlays). § 18.08.020, § 18.08.030.
• Typical uses and flexibility: The code lists named P‑D districts (e.g., P‑D/1 Jefferson Springs, P‑D/5 Bandiera Winery) with their own adopted rules; a Specific Plan (SP) district uses an "SP‑#" map symbol and may include customized lot, use, parking, and landscaping standards. § 18.08.020, § 18.08.030.

Checklist

• Confirm base zoning for the parcel on the official zoning map (zoning map kept by city clerk / planning director) § 18.01.060.
• Determine whether the desired change is accomplished by a P‑D, SP, PUD permit modification, conditional use permit, or a formal zoning map amendment; follow § 18.03.080, § 18.08.020, § 18.08.030, § 18.05.050.
• Meet design review submittal requirements where triggered (see § 18.03.150) and consult the Cloverdale Design Review page for procedural details.
• Prepare findings and neighborhood/context analyses required for conditional permits and map amendments (see § 18.03.110 and § 18.03.080).
• Demonstrate compliance with applicable Cloverdale Parking and Cloverdale Development Standards chapters (see Chapters 18.11, 18.04, 18.06).
• If historic resources are involved, include a historic report and preservation plan when requested (historic exceptions referenced in § 18.05.050 and O‑R notes).
• Verify whether ADU proposals must also follow state ADU law in addition to local ADU standards; see Cloverdale ADUs and California ADU law. (Local ADU code reference: § 18.09.180 — Not quoted verbatim here; verify with the code.) Not found in retrieved materials: a single consolidated “overlay” procedure.

Risks & Ambiguities

Information Gaps

• A code section explicitly titled “Overlay Districts” or “Combining Districts” was not found in the retrieved Cloverdale Title 18 materials. Not found in retrieved materials.
• If Cloverdale maintains a separate overlay map or a locally‑named overlay (e.g., flood, airport, historic overlay), that map or ordinance text was not present in the retrieved document set. Verify with the city clerk / planning department. Not found in retrieved materials.

Plain‑English Summary

Cloverdale does not use a titled “overlay district” chapter in the retrieved zoning code; instead, the city achieves the same site‑specific regulatory results by creating Planned Development or Specific Plan districts, by approving PUD (PUD/PUD‑style) modifications and conditional permits, and by using design review and historic review to add site‑specific requirements. Always check the official zoning map and the ordinance adopting any P‑D or SP for the parcel in question. § 18.08.020, § 18.08.030, and § 18.03.080 are the most relevant code places to start.
