Lassen County — Parking

Last reviewed: July 6, 2026

Overview

This page explains how off-street parking and loading are regulated in the unincorporated areas of Lassen County under Title 18 (Zoning). Countywide standards live in Chapter 18.104 and are supplemented by district-specific rules in commercial, industrial, business park, and planned community districts. Use this together with the broader Lassen County Zoning, Development Standards, and Design Review pages to understand how parking integrates with site planning.

Headline rule: No required front or street-side yard may be used for required off-street parking, except in commercial or industrial districts where allowed elsewhere in the title. See § 18.104.010 .

Countywide parking and loading (Chapter 18.104)

• Required by use:
  • Residential: Single-family, duplex, and multifamily dwellings require 2 spaces per dwelling unit. Senior housing may reduce to 1.5 spaces per unit; cooperative dorms/boardinghouses require 1 space per 2 occupants; hotels/motels require 1 per guestroom under § 18.104.010 .
  • Commercial examples (apply countywide unless a district supplies a stricter standard): restaurants/nightclubs 1 per 4 seats; drive-ins 1 per 100 sf GFA + 1 per 2 employees; retail stores 1 per 200 sf GFA; shopping centers 1 per 200 sf GFA, and for centers >30,000 sf, 1 per 300 sf GFA; theaters 1 per 4 seats; launderettes 1 per 5 machines; furniture/appliance stores 1 per 600 sf GFA; dance/assembly halls 1 per 4 fixed seats or 1 per 100 sf if not fixed-seating; funeral homes 1 per 4 fixed seats (or 1 per 28 sf of assembly area if no fixed seating), under § 18.104.010 .
  • Industrial examples: warehouses/wholesale 1 per 2,000 sf GFA + 1 per 2 employees (largest shift); laboratories 1 per 300 sf; machinery/equipment sales 1 per 500 sf, under § 18.104.010 .
  • Uses not listed: the Planning Commission sets a comparable standard per § 18.104.010(5) .
• Where parking can go:
  • In general, keep required parking out of sight-distance areas and out of required front/street-side yards. Single- and two-family homes may park in front/street-side yard areas; multifamily parking must sit 10 ft behind the front/street-side property line and the intervening area must be landscaped per § 18.104.020(b) .
  • Off-site parking is allowed on a separate parcel if no on-site parking is available, per § 18.104.020(c) .
• Stall and driveway geometry:
  • Standard stall: 9' x 18'; parallel stall: 9' x 24'; disabled stall: 12' x 18' (local dimension—still coordinate with the California Building Standards Code), all in § 18.104.020(d)-(f) .
  • Min commercial driveway width (“encroachment”): 24 ft for two-way; 12 ft for one-way per § 18.104.030(c)-(d) .
• Loading spaces:
  • Provide 1 loading space for the first 10,000 sf GFA, plus 1 per each additional 35,000 sf, sized 12' x 22' and clear of rights-of-way/sight areas per § 18.104.040 .
• Edge conditions next to residential:
  • Parking lots adjacent to or within an “R” district must be paved, screened by a minimum 6-ft solid fence or wall, and lit so as not to disturb residences, per § 18.104.030(g) .
• Area-specific waiver (Westwood CSD):
  • The Community Development Director may waive parking standards for commercial uses in the Westwood Community Services District if strict adherence creates undue hardship, per § 18.104.050 .

District-by-district: parking-related rules that change the baseline

The county’s base ratios in § 18.104.010–.040 apply everywhere in unincorporated areas unless a specific district sets a stricter or additional rule.

• Most new commercial/industrial projects trigger Design Review before building permits.
• Landscape strips and interior shade trees listed above dovetail with Landscaping and Screening.
• ADU parking is heavily constrained by state law; see California ADU law. State guidance limits ADU parking to a maximum of 1 space per unit/bedroom and exempts many ADUs from parking entirely (e.g., near transit) per state law summaries .
• Accessibility and bicycle parking can be governed outside zoning by the California Building Standards Code. Coordinate code paths even where zoning is silent (see also the county’s accessible stall dimension above) .

Checklist

• Identify your use category and applicable ratio under § 18.104.010 (and confirm if a district standard supersedes it).
• Confirm parking location rules (no front/street-side yard parking unless allowed; multifamily 10-ft landscape setback) per § 18.104.020.
• Size stalls and drive aisles per § 18.104.020–.030; check loading per § 18.104.040.
• If adjacent to an “R” district, show paving, a 6‑ft screen, and compliant lighting per § 18.104.030(g).
• Apply district-specific surfacing, interior tree, and landscaped strip rules (e.g., C‑L § 18.30.060, M‑1 § 18.42.060).
• If parking is off-site, document the parcel and agreement per § 18.104.020(c).
• In Westwood CSD, evaluate whether a director waiver under § 18.104.050 applies.
• Check overlays, Variances and Exceptions, and Nonconforming Uses implications before finalizing the plan.

Risks & Ambiguities

Plain-English Summary

In unincorporated Lassen County, start with the countywide ratios in Chapter 18.104, then layer on your zoning district’s surfacing, landscaping, and loading details. Most homes need two spaces per unit; common commercial and industrial uses follow listed seat/square-foot or employee formulas. Keep required parking out of required front/street-side yards (with narrow exceptions), size stalls and driveways correctly, and add interior trees and landscaped buffers where triggered.
