Siskiyou County — Parking

Parking under the Siskiyou County local zoning and planning code, with the controlling citations.

Last reviewed: July 6, 2026

Overview

This page distills how off-street parking and loading are regulated by the Siskiyou County Zoning Ordinance for unincorporated areas. The ordinance sets countywide parking ratios by use, stall and aisle geometry, basic lot design features, and when a formal plan is required. Where a parcel is in a planned development or overlay, you’ll still apply the base parking rules unless a duly adopted plan or overlay states otherwise under the Siskiyou County Zoning.

Plain-English core rule: Unincorporated Siskiyou County sets off-street parking by use category (residential, commercial, industrial), with standard stall dimensions of 9 ft by 20 ft and a 24 ft two-way aisle at 90 degrees. See § 10-6.5610 for the counts and geometry.

Countywide off-street parking and loading standards

Baseline standards. The ordinance codifies minimum off-street parking counts by use and district groupings, plus loading and geometric requirements, all applying in unincorporated areas under § 10-6.5610.
Definitions. A “parking space” is at least 9 ft by 20 ft; “off-street parking space” is a motor-vehicle storage area off public ROW and directly accessible to an aisle, guiding site design in unincorporated areas under § 10-6.3602.139 and § 10-6.3602.127.
Lot geometry. Standard stall and aisle dimensions, curb/edge barriers along property lines, and a “use the greater aisle width” rule when two angles share an aisle are all fixed by § 10-6.5610(e).
Landscaping in lots. For commercial and industrial projects, landscape at least 6% of the interior of a parking lot, dispersing shade trees throughout; also at least 6% of required frontage landscaping must sit in the 20 ft front setback under § 10-6.5609(b).
Loading. Provide off-street loading: one berth up to 10,000 sf of floor area, plus one additional berth per additional 10,000 sf, per § 10-6.5610(d).
Planned developments. In a P-D (Planned Development) district, you must submit an off-street parking and loading plan as part of the development plan under § 10-6.1187(b)(1).
Circulation tie-in. Street and on-site circulation supporting parking and loading must align with the County Land Development Manual per § 10-6.5607.
Administrative flexibility. The Planning Director may modify parking and loading requirements “as necessary,” which is a key relief route distinct from a formal Siskiyou County Variances and Exceptions process, under § 10-6.5610(e)(3).

Parking stall and lot geometry (design-critical)

Standard stalls and aisles (selected values): 90° stalls are 9 ft x 20 ft with a 24 ft aisle; 45° stalls are 9 ft x 20 ft with a 22 ft one-way aisle; parallel stalls are 9 ft x 20 ft with a 22 ft aisle. Loading spaces are 12 ft x 30 ft with 15 ft vertical clearance. All per § 10-6.5610(e).
Aisle-sharing rule: If two opposing stall-rows have different angles but share the same aisle, use the greater aisle width required by either side under § 10-6.5610(e)(1).
Perimeter protection: Spaces along property lines must be protected by a minimum 6 in x 6 in raised curb or equivalent barrier to prevent vehicle encroachment from off-site or non-maneuvering streets per § 10-6.5610(e)(2).

Bicycle parking and EV-ready

Bicycle parking: Not found in retrieved materials.
EV charging/accessible parking: These are addressed by the California Building Standards Code, not the zoning ordinance. Coordinate early so your site plan leaves room to meet Title 24 accessibility and EV infrastructure at building permit. Not found in retrieved materials for zoning specifics.

Landscaping within parking areas

Provide and disperse interior landscaping (shade trees prioritized) covering at least 6% of the interior of commercial/industrial parking lots; calculate interior area using 280 sf per space; also, at least 6% of landscape must be placed within the 20 ft front yard setback or frontage area per § 10-6.5609(b)(1)–(2).

Dimensional standards: Not found in retrieved materials.
Where it applies: Verify with the jurisdiction.

P-D (Planned Development)

Purpose/uses: Flexible, mixed configurations; must demonstrate adequate off-street parking equivalent to otherwise required standards, and submit an off-street parking and loading plan per § 10-6.1187(b)(1) and Article 11‑D purpose statement.
Parking: Ratios may be expressed as a plan-based ratio if feasibility is demonstrated; base standards still anchor adequacy under § 10-6.1187(b)(1).
Dimensional standards: Established via the approved PD plan; verify with the jurisdiction.

Overlay districts

FRZ (Fault-Rupture Zone) Overlay. Applies over base zones countywide; it does not rewrite parking ratios but may restrict development potential altogether in mapped fault-rupture zones per § 10-6.5701–.5702. Coordinate early on feasibility before finalizing a parking program and Siskiyou County Design Review.

Practical design pointers (unincorporated areas)

Early test-fit: Lay out a 90-degree module using 9 ft x 20 ft stalls with 24 ft aisles, then adjust for trees to meet the 6% interior landscape rule; add curb stops/barriers at perimeters per § 10-6.5610(e) and § 10-6.5609(b).
Use-specific counts: Pick the right row from § 10-6.5610(b)–(c); if your use isn’t listed, consult Planning about the most analogous category and whether the Planning Director will accept a modification per § 10-6.5610(e)(3).
Loading: Don’t forget the 10,000 sf trigger in § 10-6.5610(d); place loading with 15 ft vertical clearance near service entries.
Special cases in R-R: Resident-owned heavy equipment/vehicle parking has extra screening/access conditions in § 10-6.4803(d)—plan for fencing and surfacing.
Landscaping + frontage: Allocate part of your frontage landscaping to meet the 6% in the 20 ft front yard rule in § 10-6.5609(b)(1) while also satisfying the lot-interior 6% requirement.
ADUs/second units: Older local standards reference dedicated spaces; however, state rules now govern ADU parking. Coordinate with Planning and check California ADU law. Not found in retrieved materials for updated local ADU parking.

Checklist

Identify base zoning and any overlays in unincorporated areas; confirm if PD applies.
Select the correct parking ratio from § 10-6.5610(a)–(c) based on your use.
Test-fit stalls/aisles to the geometry in § 10-6.5610(e); include curbs/barriers at edges.
Provide required loading per § 10-6.5610(d), with adequate vertical clearance and maneuvering.
Meet landscape minimums inside parking and along frontages per § 10-6.5609(b), with shade trees dispersed.
If in a P-D, prepare the required off-street parking and loading plan per § 10-6.1187(b)(1).
If a unique use or constrained site, discuss a Planning Director modification under § 10-6.5610(e)(3) or explore Siskiyou County Variances and Exceptions.
Reserve space to satisfy Title 24 accessibility/EV at building permit; see California Building Standards Code.

Risks & Ambiguities

Issue	Why it matters	What to verify
Use not expressly listed in the ratio table	Misclassification can under/over-supply parking	Which listed category in § 10-6.5610(b)–(c) is the best analog; whether a modification under § 10-6.5610(e)(3) is appropriate.
Partial or phased PD projects	Parking adequacy must be shown per phase	Your P-D plan’s parking/loading ratios and phasing compliance under § 10-6.1187(b)(1).
Landscaping tradeoffs	Failure to meet both interior and frontage minimums can delay approvals	Landscape calculations meeting both 6% interior and 6% frontage under § 10-6.5609(b).
Overlay constraints (FRZ)	May preclude or condition development even if parking meets code	Whether a mapped FRZ affects the parcel under § 10-6.5701–.5702.
Accessibility/EV not planned for early	Redesigns later in permitting if Title 24 space is lacking	Coordinate early with Building Division; Title 24 lives outside zoning in California Building Standards Code.
ADU/second unit parking	State preemption can override older local ratios	Confirm current ADU parking applicability with Planning; see California ADU law.

Plain-English Summary

If you’re building in unincorporated Siskiyou County, start with the use-based parking counts in § 10-6.5610, lay out 9-by-20 stalls with the required aisles and perimeter curbs, and don’t forget a loading berth for every 10,000 sf of commercial/industrial space. Provide interior shade-tree landscaping equal to 6% of the lot’s parking interior and meet the frontage landscape piece as well. Special districts like PDs require a parking/loading plan; overlays don’t change counts but may limit development. For accessibility and EV, plan space early—those are handled at building permit under state codes.
