Point Arena — Development Standards

Last reviewed: July 2, 2026

Overview

This page summarizes the development standards that appear in the Point Arena zoning ordinance (Title 18 zoning provisions as provided) — setbacks, heights, lot-area/density rules, and related site-development requirements that control where and how you can build in each zoning district. Where the ordinance assigns discretion to the Planning Commission (for design, reduced heights/setbacks, or PRDs), I note that explicitly and point to the controlling sections. Verify parcel-specific rules with the city; anything not in the retrieved ordinance is labeled "Not found in retrieved materials." Links below point to related local topic pages referenced in the ordinance (parking, design review, overlays, ADUs, etc.).

(First mentions of related topics are linked inline: parking, design review, overlay districts, ADUs, California Building Standards Code, historic preservation, landscaping.)

This page is grounded in the retrieved Point Arena zoning materials; each rule below cites the ordinance § and the file preview used.

How to read these rules

• Numeric requirements are the objective standards the ordinance lists; where the code says the Planning Commission "may require" or "may modify," that is discretionary and flagged below (verify with the jurisdiction). See § 18.25.150 for the Commission's site and architectural review authority.
• For project-level submittal and modification rules for large or comprehensively planned developments, see the Planned Residential Development (PRD) / Comprehensive Development Plan rules. § 18.30.130 and § 18.30.140.
• Parking and landscaping requirements are applied in the ordinance and are described under specific zone rules and Chapter 18.25; see the landscaping/screening rules.

District-by-district breakdown

Note: every district description below gives the district purpose, typical permitted uses, and the ordinance-listed dimensional standards where those appear in the retrieved materials. Each numeric item is followed by the controlling § citation and the file preview marker.

SR — Suburban Residential (§ 18.20.020)

Purpose & where it applies

• The SR district applies to properties designated on the zoning map suitable for low-density single-family residential development; the ordinance frames it as intended to preserve suburban lot patterns and neighborhood character. § 18.20.020

Typical permitted uses

• Single-family dwellings, accessory structures, and customary home occupations consistent with the zone intent. § 18.20.020

Key dimensional standards

• The ordinance text for the exact numeric minimum lot area, lot width, and yard dimensions for SR are Not found in retrieved materials for a definitive single list. Verify parcel-specific standards with the city. § 18.20.020

Notes

• Projects that significantly alter site form in SR are subject to the general design/site development rules in § 18.25.150.

UR — Urban Residential (§ 18.20.030)

Purpose & where it applies

• The UR district is intended for moderate-density residential development in urbanized portions of the city. The ordinance identifies it as serving lower-to-moderate density multifamily or attached residential forms. § 18.20.030 Not found in retrieved materials (full text not shown)

Typical permitted uses

• Single-family and duplex or limited multifamily uses (depends on the full ordinance text). Not fully listed in the retrieved excerpts. Verify on the zoning map and full code. § 18.20.030

Key dimensional standards

• Specific numeric standards for UR (lot size, setbacks, heights) are Not found in retrieved materials. Verify with the jurisdiction. § 18.20.030

MR — Multifamily Residential (§ 18.20.040)

Purpose & where it applies

• The MR district is intended for medium-density multifamily apartment development and mixed residential building types; development must be served by municipal water and sewer. § 18.20.040

Typical permitted uses

• Single-family and multifamily dwellings, cohousing, live/work (except mobile homes), tot lots, and home occupations. § 18.20.040

Key dimensional standards (decision-relevant)

• Minimum lot area: 5,800 sq ft — § 18.20.040
• Minimum lot width: 60 ft — § 18.20.040
• Maximum lot depth: 3× lot width — § 18.20.040
• Minimum yards: front 20 ft; rear 10 ft; side 5 ft — § 18.20.040
• Maximum building height: 35 ft (the Planning Commission may require a lesser height under § 18.25.150) — § 18.20.040
• Maximum residential density: 1 dwelling unit / 5,800 sq ft (equivalent to the minimum lot area limit above) — § 18.20.040
• Usable open space: 15% of each lot, in addition to required yards and patios — § 18.20.040

Practical guidance

• Because MR requires municipal water and sewer as a condition precedent, expect the city to verify utility capacity during review (§ 18.20.040).

RA-2 — Residential Agriculture (§ 18.20.060)

Purpose & where it applies

• The RA-2 zone allows very low-density residential with limited agricultural activities, serving as a rural buffer and maintaining small-town character. Septic systems and wells are permitted in some circumstances. § 18.20.060

Typical permitted uses

• Farming, crop production, greenhouses, accessory barns, one single-family dwelling (mobile/manufactured allowed), and limited home occupations; conditional allowances for second units subject to the second unit ordinance and state law. § 18.20.060

Key dimensional standards

• The specific numeric lot-area/minimums and setbacks for RA-2 are Not found in the retrieved excerpts (the section text includes permitted uses and conditions but the numeric table is not shown). § 18.20.060

Notes

• Special standards apply for second dwelling units and for ensuring water/septic adequacy; check the second unit rules and Local Coastal Program references in the code. § 18.20.060

C — Core Commercial (§ 18.20.070)

Purpose & where it applies

• The C district (Core Commercial) covers the downtown/core area for retail, services, and visitor-serving uses intended to serve residents and tourists. § 18.20.070

Typical permitted uses

• Retail, professional offices, restaurants, public uses, lodging, and existing dwellings; mixed residential uses may be allowed with conditions. § 18.20.070

Key dimensional standards

• Minimum yards: front none (unless frontage abuts residential zone, then front yard of that zone applies); rear 15 ft; side none (side yard abutting a residential zone must match the residential front yard) — § 18.20.070
• Maximum building height: 35 ft (planning commission may require lesser height under design review rules) — § 18.20.070

Notes

• The Planning Commission may require a comprehensive development plan for mixed-use projects and can deny dwelling units in the core if they conflict with downtown objectives or coastal priorities. § 18.20.070

HWC — Highway Commercial (§ 18.20.080)

Purpose & where it applies

• The HWC district supports highway-oriented goods and services along Highway 1, including uses that rely on vehicle access and parking. § 18.20.080

Typical permitted uses

• All uses allowed in the Core Commercial zone plus vehicle/boat sales, fitness facilities, emergency shelters/transitional housing, and service uses; some heavier or vehicle-related uses are conditionally permitted. § 18.20.080

Key dimensional standards

• Specific numeric minimum yards, lot sizes, and maximum heights for HWC are Not shown in the retrieved excerpts in a single definitive list. The ordinance contains conditional residential use rules and requires PRDs for certain residential projects; see § 18.20.080 and PRD rules. § 18.20.080

Notes

• The Planning Commission may require comprehensive development plans for mixed residential/mixed-use projects in HWC. § 18.20.080

HC — Harbor Commercial (§ 18.20.090)

Purpose & where it applies

• Minimum yards: front 20 ft; rear 15 ft; side 10 ft — § 18.20.090
• Maximum building height: 45 ft — § 18.20.090

Notes

• For harbor areas the ordinance emphasizes priority of coastal-dependent uses and requires connection to municipal water and sewer systems where applicable. § 18.20.090

I — Industrial (§ 18.20.100)

Purpose & where it applies

• The I zone is for nonnuisance industrial activities that should be separated from residential/tourist areas. Uses that create noise, odor, or other impacts are restricted. § 18.20.100

General regulatory requirements & design controls

• Design/Architectural Review: The Planning Commission has site development and architectural review authority over relocation, construction, additions, and landform alteration; projects require commission approval and a coastal development permit as prescribed in Chapter 18.30 (except for interior remodels that do not alter external profile). See § 18.25.150. Design review link: /us/california/point-arena/design-review.
• Landscaping & Screening: New development in MR, C, HWC, HC, and I must submit landscaping and screening plans meeting specified criteria (maintenance, perimeter landscaping for parking, screening for nonresidential uses abutting residential uses, prohibition on invasive species). See § 18.25.140. Landscaping link: /us/california/point-arena/landscaping-and-screening.
• Comprehensive/PRD Plans: Projects on parcels ≥ 10 acres (or assemblies equal to 10+ acres) require a comprehensive development plan and PRD processing; PRD may allow modifications of underlying zone standards (height, yards, lot sizes) only upon written findings and public benefit. See § 18.30.130 and § 18.30.140.
• Coastal & Environmentally Sensitive Areas: Certain excavations, bluffs, riparian corridors, and wetlands are restricted and subject to coastal development permit conditions (see § 18.25.220 and related subsections referenced throughout Chapter 18.25). Not all detailed restrictions were in the retrieved excerpts; verify with the LCP map and code.

Related topics you will need to check during application: parking, overlay districts, historic preservation, and signage rules. The code also references the state California Building Standards Code for building-safety standards — building code requirements are separate from these zoning development standards.

Checklist

• Confirm zoning designation for the parcel on the zoning map (match to the district summaries above) — Verify with the jurisdiction. § 18.15.050
• Confirm basic dimensional standards for that district (min lot area, width, depth, yards, max height) from the full code or planning staff. See district § cited above.
• Check utilities requirement (MR, HC, HWC often require municipal water/sewer) and whether the site is eligible for septic/well (RA-2, some I/PF conditions). § 18.20.040, § 18.20.090, § 18.20.060
• Determine whether design review / Planning Commission approval is required and prepare materials per § 18.25.150 (site siting, elevations, landscaping). § 18.25.150
• For projects ≥10 acres or proposed PRDs, prepare a comprehensive development plan per § 18.30.140. § 18.30.140
• Prepare landscaping and screening plan for MR, C, HWC, HC, I as required by § 18.25.140 (include tree wells for parking areas where applicable). § 18.25.140
• Verify whether any overlays, riparian buffers, floodplains, or fault setbacks apply to the parcel; consult the Local Coastal Program and overlay maps. Verify with the jurisdiction.

Risks & Ambiguities

Plain-English Summary

Point Arena’s zoning ordinance sets district-by-district rules for lot size, setbacks, and height (for example, MR allows 35 ft height and 20 ft front setbacks with 5,800 sq ft minimum lots), and gives the Planning Commission authority to require design review and, in some cases, to modify numeric standards for public benefits or coastal/resource protection. You must confirm the parcel’s exact zone and whether coastal overlays or PRD requirements apply; plan on design review and landscaping plans for most non-single-family projects. § 18.20.040; § 18.25.150.
