Point Arena — Nonconforming Uses
Nonconforming Uses under the Point Arena local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
This page summarizes how the City of Point Arena treats nonconforming uses, nonconforming structures, and nonconforming lots under the local zoning ordinance (Title 18, Zoning). For the broader context on local policy and maps, see the Point Arena zoning & planning overview. The rules that control whether an existing (lawful) nonconforming use can continue, be changed, rebuilt, or expanded are in the general provisions chapter; off‑street parking, lots, and rebuilding thresholds are dealt with separately in the same chapter.
What the ordinance says (core rules)
- A lawful use or structure that existed when the ordinance became effective may continue even if it does not meet current standards — but only to the extent and under the limits the code allows. See § 18.25.170 .
- A structure that is nonconforming only because of lot area, yards, height or similar dimensional issues may be altered, repaired or extended provided the alteration does not increase the existing degree of nonconformance. See § 18.25.170(1) .
- If a nonconforming building is destroyed or repaired and the cost of repair using new materials exceeds 60 percent of the current appraised value, the rebuilt structure must comply with the current zone regulations. The ordinance requires repair to commence within one year and allows an additional six months to complete exterior reconstruction. See § 18.25.170(2) .
- A nonconforming use may not be changed to another nonconforming use; changes must be to a conforming use. A nonconforming use discontinued for one year or more cannot be reestablished. A nonconforming use of only part of a structure cannot be extended to cover the whole building. See § 18.25.170(3) .
- Uses that require a conditional use permit are treated as nonconforming until the required permit is obtained. See § 18.25.170(4) .
- Nonconforming lots that were lawfully created (recorded subdivision map or otherwise lawfully established) are treatable as legal building sites for permitted uses of the zone, even if they do not meet current minimum lot area — subject to satisfaction of the other requirements of the code. See § 18.25.180 .
- Nonconforming off‑street parking in existence on the effective date is counted as the required parking for that specific use; changes to use, building, or parking must follow the special provisions in § 18.25.190 (including providing parking for any expansion or for changes to a use that increase parking demand). See § 18.25.190 — consult the city's parking standards for calculations and in‑lieu options via the parking page.
Note: site design, architectural review and many rebuild/alteration approvals go through the planning commission under the city's design review/site development rules; see § 18.25.150 for the planning commission role and design criteria. See the design review page for procedural expectations. § 18.25.150 .
District-by-district practical breakdown (where nonconforming rules apply)
Below are the principal zones in the Point Arena code with the short purpose, typical permitted uses, key dimensional standards, and where that zone is applied in the city. In every zone the general nonconforming rules above (Chapter 18.25) apply to pre‑existing lawful nonconforming uses/structures.
SR 1 (Suburban Residential — One Acre) — § 18.20.020
- Purpose: low‑density single‑family residential and small‑scale agriculture buffer.
- Typical permitted uses: single‑family dwellings, small farms, accessory structures, home occupations (principally permitted); some conditional uses (bed & breakfast, second units) are listed in the SR rules. See § 18.20.020 .
- Key dimensional standards: minimum lot area: one acre, minimum lot width: 125 ft, yards: front 20 ft / rear 15 ft / side 10 ft, max height: 35 ft. See § 18.20.020(c) .
- Application: larger single‑lot suburban areas and rural edges shown on the zoning map.
SR 1/2 (Suburban Residential — One‑Half Acre) — § 18.20.020
- Same purpose and uses as SR 1. Key change: minimum lot area: one‑half acre (other setbacks and height follow SR standards). See § 18.20.020(2)(c) .
RA‑2 (Residential Agriculture) — § 18.20.060
- Purpose: very low‑density residential with limited agricultural uses.
- Uses: small farms, one single‑family dwelling (mobile/manufactured allowed), accessory agricultural buildings; conditional uses include animal hospitals, stables, bed & breakfast and one second dwelling unit per the second unit ordinance. See § 18.20.060 .
- Dimensional standards: minimum lot area: two acres, minimum lot width: 250 ft, yards: front 20 ft / rear 15 ft / side 10 ft, max height: 35 ft. See § 18.20.060(3) .
MR (Multifamily Residential) — § 18.20.040
- Purpose: medium‑density residential and mixed residential/office types.
- Uses: single‑family and multifamily dwellings, live/work, home occupations; conditional uses include inns, offices, day‑care. See § 18.20.040(1–2) .
- Key standards: minimum lot area: 5,800 sq ft, min lot width: 60 ft, yards: front 20 ft / rear 10 ft / side 5 ft, max height: 35 ft, max density: 1 unit / 5,800 sq ft. See § 18.20.040(3) .
C (Core Commercial) — § 18.20.070
- Purpose: downtown goods, services, offices, and urban housing.
- Uses: retail, restaurants, services, offices, visitor‑serving facilities; some residential allowed. See § 18.20.070(1–2) .
- Key standards: varied; often no front yard when fully commercial, max height: 35 ft, sidewalks required. See § 18.20.070(4) . Nonconforming commercial uses subject to the general rules in § 18.25.170 .
HWC (Highway Commercial) — § 18.20.080
- Purpose: highway‑oriented goods & services that need easy access and parking (Highway 1).
- Uses: all C uses plus vehicle sales, fitness facilities, emergency shelters, and certain conditional industrial/warehouse or vehicle services when screened. See § 18.20.080(1–2) .
HC (Harbor Commercial) — § 18.20.090
- Purpose: Arena Cove coastal‑dependent commercial and visitor services; coastal‑dependent uses have priority.
- Uses: boat launching, boat repair, fish processing, visitor‑serving retail, and related public facilities (many uses conditional). See § 18.20.090 .
- Special: coastal policies and ESHA buffers are commonly relevant in HC; nonconforming marine or harbor uses are governed by the general nonconforming rules and coastal permit requirements. See § 18.25.220 .
I (Industrial) — § 18.20.100
- Purpose: non‑nuisance industrial activities requiring screening and control of emissions.
- All uses require a conditional use permit; key standards include min lot area: 10,000 sq ft, min width: 80 ft, setbacks: front 30 ft / rear 20 ft / sides 20 ft, max height: 45 ft. See § 18.20.100(1) .
PF, P, OS (Public Facility; Park; Open Space) — § 18.20.110–130
- PF: public uses and utility facilities — most uses are conditional and site‑specific standards are set by the planning commission. See § 18.20.110 .
- P: parks and recreation uses; standards emphasize public access and facilities. See § 18.20.120 .
- OS: permanent open space with very limited building allowances; see § 18.20.130 .
Every district above is subject to the general nonconforming rules in § 18.25.170–190 (continuance, repair threshold, discontinuance, lots, and parking) , and site development/design review § 18.25.150 for alterations and additions .
Quick reference table — common decision points
| Issue | Rule in plain words | Code Reference |
|---|---|---|
| Can an existing nonconforming use continue? | Yes — lawful uses existing on the ordinance effective date can continue, subject to limits below. | § 18.25.170 |
| Repair/rebuild after damage | If repair cost > 60% of current appraised value, rebuilt structure must meet current zone regulations; work must start within 1 year. | § 18.25.170(2) |
| Discontinued use | If a nonconforming use is discontinued for one year or more, it cannot be reestablished. | § 18.25.170(3) |
| Nonconforming lots | Lawfully established recorded lots that are undersized remain legal building sites for permitted uses if other code requirements can be met. | § 18.25.180 |
| Nonconforming parking | Existing nonconforming parking at time of ordinance counts as required parking for that use; expansions/changes trigger parking provisions. | § 18.25.190 |
| Design/site review for changes | Most relocations, exterior remodeling, additions require planning commission review and a coastal development permit when applicable. | § 18.25.150 |
Checklist — what an applicant should prepare for a nonconforming‑use/structure proposal
- Establish that the use/structure was lawfully existing on the ordinance effective date (title, recorded map or permit history). See § 18.25.170 .
- If proposing repair/rebuild, obtain an appraisal and construction cost estimate to test the 60% threshold under § 18.25.170(2) .
- If the site is an undersized lot, demonstrate that other code requirements (setbacks, septic/water, parking, ESHA buffers) can be met per § 18.25.180 .
- Provide parking calculations and demonstrate compliance with § 18.25.190 (or supply an in‑lieu fee proposal where applicable); review the city's parking standards on the parking page. See § 18.25.190 .
- Submit design/site plans addressing § 18.25.150 design criteria and any coastal development permit requirements; be ready for planning commission review. See design review page and § 18.25.150 .
- If in or adjacent to an ESHA or riparian buffer, supply habitat/buffer analysis and special findings per § 18.25.220–240 (environmental review). See overlay districts and ESHA rules § 18.25.220 .
- Prepare evidence of adequate services (water/sewer) and traffic capacity for the proposed continuation or change per zone sections (e.g., § 18.20.040, § 18.20.070) .
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Rebuild cost threshold (the 60% test) | If reconstruction costs exceed 60% of current appraised value the structure must meet current code — this can eliminate existing nonconforming relief. | Verify appraised value methodology, obtain pre‑construction estimate, and confirm the city’s interpretation and required documentation per § 18.25.170(2) . |
| Discontinuance clock | The one‑year discontinuance rule can cause loss of nonconforming rights if use stops. | Document continuous operation; for intermittently used businesses collect permits, tax records, lease history to show continuity (see § 18.25.170(3)) . |
| Nonconforming lot usability | A legal undersized lot may still fail other standards (setbacks, septic, ESHA). | Verify physical ability to meet setbacks, septic and other zone requirements and coastal/habitat rules; nonconforming lot rule is permissive but conditional (see § 18.25.180). |
| Parking carried forward | Existing nonconforming parking can be “frozen” for that use but expansions or changes trigger parking compliance. | If you plan change of use or expansion, compute additional parking obligations and review in‑lieu options in § 18.25.190 . |
| ESHA / riparian buffers | Nonconforming uses inside buffer zones are allowed to continue but additions that encroach closer are generally prohibited without special findings. | Confirm buffer mapping, work with resource agencies, and collect the four findings required for exceptions (see § 18.25.220 and related sections) . |
| Coastal Development Permit interplay | Many coastal‑area nonconforming situations still require CDPs; the LCP rules can restrict what can be continued or rebuilt. | Confirm CDP applicability and the specific coastal findings required in Chapter 18.30 and the general plan/local coastal program. Verify with city staff. . |
Plain‑English summary
If your building or business in Point Arena was legal under older rules, you can generally keep it — but you cannot enlarge the nonconforming part, you cannot change to a different nonconforming use, you must rebuild to current code if damage/repair exceeds the 60% threshold, and an undersized lot that was lawful before still can be built on provided you meet the other standards; see § 18.25.170–190 for the exact limits.

Frequently asked questions
What are Point Arena's core rules for nonconforming uses?
Point Arena allows lawful pre‑existing uses and structures to continue, but they may not be changed to another nonconforming use, cannot be reestablished after being discontinued for one year, and repairs/extensions cannot increase the degree of nonconformance; major rebuilding that costs more than 60% of appraised value must meet current zone rules. See § 18.25.170.
Are undersized (nonconforming) lots buildable in Point Arena?
Yes — a lot lawfully established on a recorded map or lawfully separate on the ordinance effective date is considered a legal building site for uses permitted in the zone, but you still must meet other code requirements (setbacks, services, environmental rules). See § 18.25.180.
If my nonconforming building burns down, can I rebuild it in the same footprint?
You can rebuild, but if the cost of repair/reconstruction (using new materials) exceeds 60% of the current appraised value the rebuilt building must comply with the current zone standards; repair must commence within one year (with six more months to finish exterior). See § 18.25.170(2).
Does existing nonconforming parking still count toward required parking?
Yes — off‑street parking facilities lawfully existing on the ordinance effective date are considered the required parking for that specific use; however, if you change or expand the use or building, you must provide parking for the expansion or difference per § 18.25.190. See § 18.25.190.
Can I expand a nonconforming use into other parts of the building or lot?
No — a nonconforming use of part of a lot or structure may not be extended throughout the lot or structure. Any change of a nonconforming use must be to a conforming use. See § 18.25.170(3).
Do I need planning commission design review to alter a nonconforming structure?
Most relocations, external remodeling, additions and other site alterations require planning commission review and normally a coastal development permit when in the coastal zone; design/site criteria are in § 18.25.150. See § 18.25.150.
Will ESHA/riparian buffers stop me from repairing or expanding a nonconforming use?
Pre‑existing buildings and nonconforming uses within riparian buffer zones may continue as legally nonconforming, but additions that encroach closer to the stream are generally not allowed except under narrow exceptions and required findings. See § 18.25.220.
How does the nonconforming rules interact with different zones (e.g., MR, C, HWC)?
The Chapter 18.25 nonconforming provisions apply across all zones; whether a rebuilt or altered use is allowed also depends on the underlying zone standards (for example MR standards in § 18.20.040, C in § 18.20.070, HWC in § 18.20.080) and the planning commission's design review findings. See § 18.25.170 together with the applicable zone section.
Can nonconforming zoning conditions block creation of an ADU?
Point Arena's zoning ordinance text does not specifically address ADU approvals in the nonconforming rules found; state ADU law can limit a local agency’s ability to require correction of physical nonconforming zoning conditions. For local ADU rules see the city's ADU page and verify with planning staff (Not found in retrieved materials in the Point Arena zoning text). Verify with the jurisdiction.
