Cloverdale Zoning, Planning & Building Codes

Last reviewed: July 1, 2026

Overview

Cloverdale’s land use rules are codified in Title 18 — Zoning of the municipal code (the zoning ordinance) and implement the City’s general plan. The code organizes the city into distinct zoning district families (residential, commercial, industrial, public/institutional and special districts) and supplements them with citywide development and design standards, a permit/review matrix, and special-purpose chapters (e.g., ADUs, parking, signs, historic provisions). The planning director, planning commission and city council share roles in approvals; the code also explicitly integrates state housing and building law where applicable. See § 18.01.010 for the title and purpose of the zoning code and the code’s applicability to all properties in Cloverdale.

How Cloverdale's code is organized

• Title and purpose: The zoning ordinance is titled Title 18 — Zoning; its general provisions (purpose, applicability, consistency with the general plan) are at § 18.01.010–§ 18.01.060.
• Table of contents / chapter structure: Title 18 is arranged into chapters for administration/enforcement (Chapter 18.02), land-use permits and approvals (Chapter 18.03), residential (Chapter 18.04), commercial (Chapter 18.05), industrial (Chapter 18.06), public institutional (Chapter 18.07), special districts (Chapter 18.08), special provisions (Chapter 18.09), design standards (Chapter 18.10), signs (Chapter 18.12), and parking/loading (Chapter 18.11). The table-of-contents format is shown in the Title 18 index.
• Where to find major rules:
  • Permit and review procedures (conditional use permits, variances, PUD/PUD permits, plot plan review): Chapter 18.03 (see § 18.03.100–§ 18.03.140).
  • Citywide design standards: Chapter 18.10 and the design‑review rules in § 18.03.150.
  • Development standards and use tables: Chapter 18.04 (residential), 18.05 (commercial), 18.06 (industrial), and the special‑provisions Article in Chapter 18.09 (includes ADUs, SROs, home occupations, etc.).

Zoning district families (what the code actually uses)

The code groups districts into families and gives them the following labels (bolded here as they appear in the ordinance):

• Residential family: R-R (rural/residential), R-1 (single‑family), R-2 (low‑density multi), R-3 (multifamily). Base residential district rules and densities are in § 18.04.020–§ 18.04.050.

• Commercial family: DTC (Downtown Commercial), TOD (Transit‑Oriented Development), O-R (Office/Multifamily Residential), G-C (General Commercial) and other commercial subcategories described in Chapter 18.05; the intent statements for O‑R, DTC and TOD are at § 18.05.020.

• Industrial family: M-1 (General Industrial) and M-P (Industrial Park) with site standards and permitted/conditional uses in § 18.06.020–§ 18.06.040.

• Public/Institutional: PI (Public Institutional) — see Chapter 18.07 for uses and site standards.

• Special zoning districts / overlays: P‑D / PD (Planned Development), SP (Specific Plan / Specific Plan zoning district), and site‑specific P‑D districts (e.g., P‑D/1 Jefferson Springs, P‑D/3 Solar Park, etc.). Those special‑district rules are in Chapter 18.08 and the P‑D listings and special plan rules are in § 18.08.010–§ 18.08.040.

Practical orientation: the code ties zoning to the general plan and the official zoning map; any change of district requires the rezoning/amendment procedures in § 18.03.080.

Citywide development standards (high‑level)

• Where they live: Each district chapter contains tables of site development standards (lot area, lot width, setbacks, height, lot coverage, FAR where applicable). See residential site standards at § 18.04.050 and commercial site standards at § 18.05.040. For industrial site standards, see § 18.06.040.

• Typical numeric controls called out in the residential tables (examples the code itself shows): maximum building height commonly 35 ft or 2 stories for primary residential structures (with lower accessory limits noted), minimum building separations and lot‑size tiers, and notes about buffers adjacent to industrial zones and waterways — see § 18.04.050 (table and notes). These numeric entries and footnotes drive the city’s lot/height/setback expectations.

• Floor‑area ratio (FAR) and lot coverage: The code applies FAR and lot‑coverage limits in the district tables (residential/commercial) and explicitly treats ADUs for FAR and density purposes in § 18.09.180 (ADU rules).

• Setbacks and projections: Modifications and allowed projections (eaves, porches, bay windows) are spelled out in Chapter 18.04 (see § 18.04.050 notes and related provisions).

• Parking: Off‑street parking and loading rules are in Chapter 18.11; the code calls out special regulations for truck parking, downtown parking areas and design/paving/landscaping standards for parking lots (e.g., § 18.11.070–§ 18.11.150). See the parking chapter for dimensional, surfacing, screening and maintenance requirements. — Cloverdale’s specific parking rules are collected at Cloverdale Parking.

• Landscaping and screening requirements: Special provisions for screening, fencing, hedges and landscaping are in Chapter 18.09 (see § 18.09.030 and cross‑references in the site‑standards notes). — see Cloverdale Landscaping and Screening.

• Signs: Regulated in Chapter 18.12 (sign regulations) with a planned‑sign program and administrative sign permit procedure referenced in § 18.03.170. — see Cloverdale Signage.

Design review, discretionary review & variances

• Design review: The planning commission serves as the design review committee; the design review procedures (major and minor) and intent are in § 18.03.150, and the code requires design review for conditional uses that include new construction or exterior changes. Objective design standard language and residential/commercial guidelines are in Chapter 18.10 and § 18.03.150. — see Cloverdale Design Review.

• Discretionary permits: Conditional use permits, PUD permits, specific plans and planned development approvals require findings and public hearings per Chapter 18.03 (notably § 18.03.110 for conditional use permits and § 18.03.130 for PUD permits). The planning commission is the decision body for many discretionary approvals and can attach conditions to ensure consistency with the general plan.

• Variances and exceptions: Variances to dimensional standards (front/side/rear yards, height, parking) are processed under § 18.03.140; the code sets the standard findings (special circumstances, not self‑created, no grant of special privilege). Minor exceptions/home‑occupation rules are in § 18.03.180–§ 18.03.200.

• Nonconforming uses: Rules for nonconforming uses, structures and signs are in § 18.02.090, which governs how prior‑legal uses/structures are treated when they don’t meet new rules. — see Cloverdale Nonconforming Uses.

Specific plans & overlays (what matters in Cloverdale)

• Specific plans and special zoning districts: The code establishes a Specific Plan (SP) zoning district and sets the application and minimum content standards in § 18.03.080 and Chapter 18.08; the Alexander Valley Resort Specific Plan is called out as an active specific‑plan district in § 18.08.040.

• Planned developments / PDs: PD districts and site‑specific PD provisions are in Chapter 18.08 (see § 18.08.010–§ 18.08.020), including the list of P‑D/1 through P‑D/6 examples (Jefferson Springs, Solar Park, Bandiera Winery, etc.).

• Downtown / Transit areas: The code contains a strong downtown emphasis — DTC and a TOD district are intended to support pedestrian‑oriented, transit‑supportive development and are described at § 18.05.020; the station/downtown precise plan is specifically referenced.

• Historic overlays & conservation: Historic design review and procedures are provided in § 18.03.160 (historic design review) and the design chapter contains corridor/area standards (e.g., Cloverdale Boulevard, Asti Road). The code allows modifications/waivers for properties that meet historic‑designation criteria. — see Cloverdale Historic Preservation and Cloverdale Overlay Districts.

Building permits & review path (how a project actually moves)

• Who runs the intake and initial review: The planning director administers Title 18, determines completeness, processes CEQA documentation, collects fees, posts notices, prepares reports and may administratively approve certain permits consistent with the permit matrix (§ 18.02.070).

• Typical permit sequence:

  1. Pre‑application / zoning verification (identify zoning district per § 18.01.060).
  2. Application submitted to planning director; if plot plan review is required the planning director acts (or forwards to planning commission) under § 18.03.120.
  3. If discretionary (CUP, PUD, variance, specific plan), public hearing(s) follow per Chapter 18.03 (§ 18.03.050 notice rules and hearing procedures).
  4. Design review: required for new construction and exterior changes for discretionary permits (see § 18.03.150).
  5. After entitlement approval, building permit applications are processed by the building department; where state building or fire codes apply the project must conform to those codes (Title 24 and local building/fire code requirements are referenced in the ADU and general development provisions). Example: ADUs must comply with building and fire codes as a precondition to issuance (§ 18.09.180).

• Permit timelines and expiration: Many approvals expire in two years if no building permit is issued; the code’s permit table and expiration entries are in Table 18.03.100 and related sections of Chapter 18.03.

State housing law in Cloverdale — how state rules interact with local code

Cloverdale’s zoning code expressly references and integrates state housing and density law in several places; below is a practical summary.

ADUs / JADUs

• Local ADU chapter: Cloverdale regulates accessory dwelling units in § 18.09.180 (Accessory dwelling units) and junior ADUs in § 18.09.185. The local rules: size tiers (for small and larger lots), attachment/detachment rules, ADU counts on multifamily parcels (caps and conversion rules), and design/setback/height rules are all in § 18.09.180. Notable local specifics include maximum ADU sizes by lot size (examples: up to 850 sq ft on lots under 6,000 sq ft, up to 1,200 sq ft on lots 6,000+ sq ft; limits for multiple ADUs are stated in the section) and that ADUs are exempt from density calculations; the section also requires compliance with building/fire codes. See § 18.09.180 for the full list of ADU provisions. — see Cloverdale ADUs and California ADU law.

• Parking and ADUs: The code specifically waives additional parking for ADUs in many cases (no additional parking required and no replacement parking required when a garage is demolished to build an ADU) — see § 18.09.180(9).

• Timing: ADU review timelines (building permits for ADUs) are referenced — the ordinance states ADU review shall be completed within 60 days of submittal for complete applications for parcels with an existing dwelling (§ 18.09.180(12)).

• Interaction with state law: The local code implements ADU standards but also defers to state building and fire codes for technical compliance as required by state law; see § 18.09.180 (ADU compliance and exemptions).

Density bonus and state density law

• Cloverdale’s code allows densities to be increased consistent with State Density Bonus Law and references Chapter 18.13 as the local density‑bonus implementation location (notes in the residential/commercial site‑standards tables state density may be increased under State Density Bonus Law and/or Chapter 18.13). See the table notes in § 18.04.050 and § 18.05.040. — see California housing laws.

SB‑9, SB‑10, rent control, and other state items

• SB‑9 (ministerial lot splits and duplex allowances) or SB‑10 are not expressly implemented or called out by name in the retrieved Title 18 excerpts. The code does include mechanisms for lot‑size minimums, PUDs, PDs and allows specific plan rezoning — but explicit SB‑9 ministerial compliance language was Not found in retrieved materials; verify with the city planning department for any recent SB‑9 implementing regulations or objective standards. Likewise, there is no rent‑control ordinance language visible in the retrieved Title 18 materials — Not found in retrieved materials; consult the city clerk or housing authority for local renter protections.

Practical tip: because state ADU and density bonus laws preempt or bind local rules in certain respects, always check current state law and the City’s adopted implementing ordinances; the code contains multiple cross‑references to state law and to Chapter 18.13 for density bonus implementation.

Quick checklist for common projects in Cloverdale

• Small remodel/no change to footprint: verify zoning compliance; planning director may issue zoning clearance (see § 18.02.070).
• New single‑family home / subdivision: consult Chapter 18.04 site standards § 18.04.050, and PUD/provisional rules if clustering is proposed (§ 18.04.060 / § 18.03.130).
• New commercial in downtown/TOD: consult § 18.05.020–§ 18.05.050 (DTC/TOD/O‑R intent), Chapter 18.10 design controls, and Chapter 18.11 parking requirements.
• ADU: review § 18.09.180 for size, setback, height and parking exemptions and expect a 60‑day clock on a complete ADU application.

Information Gaps and verification pointers

• SB‑9 / ministerial lot split implementation language was not found in the retrieved Title 18 excerpts; confirm with Cloverdale planning staff whether objective SB‑9 standards were adopted after the version of Title 18 we reviewed. Not found in retrieved materials.
• Any recent updates (2024–2026 ordinances) that amend the code beyond the retrieved files should be verified on the City’s code page or by contacting the planning department; the eCode360 snapshots include ordinance amendment notes but may not reflect the absolute latest administrative interpretations.
