Humboldt County — Parking

Last reviewed: July 3, 2026

Overview

This page summarizes how the Humboldt County zoning and planning ordinance regulates parking in the county’s unincorporated areas. It explains the county’s off‑street parking, loading, handicapped and bicycle parking rules, and how those requirements interact with specific zoning districts and special development rules (for example, Accessory Dwelling Units (ADUs) and Commercial Residential projects). For on‑site building requirements (Title 24 / state code) see the California Building Standards Code. This page interprets the County Code; always verify site‑specific questions with County staff.

Key countywide rules (what the code actually says)

• The county’s off‑street parking rules are codified at § 314-109.1 and apply in all zones in unincorporated Humboldt County; the purpose is to provide minimum on‑site parking to reduce street congestion and protect pedestrian/vehicle safety (§ 314-109.1.1) .
• Required parking must generally be located on the same site and be independently usable; substitute or shared off‑site parking is allowed only under narrow findings (§ 314-109.1.3.1) .
• The Code contains a parking schedule and uses table under § 314-109.1.4 (minimum spaces by use). If a use is not listed the Director sets a comparable standard (§ 314-109.1.3.9) .
• Exceptions and reductions can be approved by Special Permit or other discretionary approvals where the Hearing Officer or Planning Commission makes stated findings (for geographic/topographic constraints, historic structures, Rural Centers, proximity to urban areas, or transit access) (§ 314-109.1.3.12; § 314-109.1.5.2) .
• Loading spaces: minimum one (1) loading space per 20,000 sq ft gross floor area (with ability to eliminate loading requirement for ≤10,000 sq ft by Director decision or to modify by Special Permit) (§ 314-109.1.5.1) .
• Handicapped parking: dimensional standards and ratios are specified (e.g., 14 ft × 18 ft for accessible stalls; one accessible space required for 6–40 total stalls, then one per each additional 40 or portion thereof) (§ 314-109.1.3.8) .
• Landscaping and lighting for parking: the Planning Commission may require landscaping (recommended minimum 2% of parking area) and lighting must be shielded so direct rays are confined to the property (§ 314-109.1.6.2; § 314-109.1.3.7) .
• The County allows shared‑parking and parking reductions for certain mixed/commercial residential projects where transit, walkability, or evidence demonstrates lower demand (see the Commercial Residential rule at § 314-56.5.3) .

District-by-district breakdown (how parking rules interact with specific Humboldt County zones)

Note: these summaries apply only to unincorporated areas and reference the County Code excerpts that control parking quantity/layout. Where district‑level rules refer back to the off‑street parking standards, the controlling County off‑street parking sections remain § 314-109.1 and subsections.

MU1: MIXED USE (URBAN)

• Purpose & where it applies: The MU1 zone facilitates compact, mixed residential and commercial development in urban unincorporated communities; see § 314-9.1 for the MU1 rules (landscaping and lighting tied to parking changes) .
• Typical permitted uses: small retail, offices, multi‑unit housing, live/work. Parking is required for new development per § 314-109.1, but MU1 explicitly references that parking requirements follow § 314-109.1 and that mixed‑use reductions or shared parking can be approved (see MU1 parking subrules) (§ 314-9.1.1.3) .
• Key dimensional/parking standards: landscaping is required when a project creates five (5) or more new parking spaces; lighting must be shielded; mixed‑use projects may qualify for up to 50% reduction for residential parking through special permit or administrative route when supported by evidence (§ 314-9.1.1.1; § 314-9.1.1.3; § 314-109.1) .

MU2: MIXED USE (RURAL)

• Purpose & where it applies: MU2 supports small‑scale mixed uses in rural centers and smaller population bases; the zone can be modified by Special Area Combining Zones (e.g., Design Control) (§ 314-9.2) .
• Typical permitted uses: neighborhood commercial, small offices, limited residential. Parking quantity follows § 314-109.1; rural context supports special permit exceptions for topography or historic buildings (§ 314-109.1.3.12) .
• Key points: Because MU2 often covers constrained rural sites, the Code contemplates Special Permits to modify parking or loading where justified (§ 314-109.1.5.2; § 314-109.1.3.12) .

Commercial Zones: C‑1 (Neighborhood Commercial), C‑2 (Community Commercial), C‑3 (Industrial Commercial), CH (Highway Service Commercial), MB (Business Park)

• Applicability: commercial residential rules (Section § 314-56.5) apply to these zones for mixed residential/commercial projects where public water/sewer are available; parking standards refer back to § 314-109.1 (§ 314-56.5.2–3) .
• Typical uses: retail, restaurants, offices, light industrial (C‑3), service uses (CH, MB).
• Key dimensional/parking standards: commercial residential projects in these zones may obtain administrative permit approval to reduce required residential vehicle parking by up to 50% or permit shared parking across uses on a single site where demand doesn’t conflict; the Code requires documentation of transit proximity, pedestrian/bicycle connections, or peak demand evidence to support a reduction (§ 314-56.5.3; § 314-109.1.3.6) .

P: PLANNED UNIT DEVELOPMENT (P)

• Purpose & where it applies: PUD regulations (Section § 314-31.1 P) govern site planning, including parking pod layout, guest parking, and RV storage for planned residential developments; the PUD delegates to the off‑street parking chapter for quantity and design standards (§ 314-31.1.7.4) .
• Typical uses: residential subdivisions, clustered housing.
• Key points: PUDs may cluster parking in pods and require guest parking up to one (1) space per two (2) dwelling units if the Commission finds it necessary; parking must be designed to meet the off‑street parking and loading standards (§ 314-31.1.7.4.1–.2) .

Residential uses and ADUs

• General: Minimums for residential parking and how to count spaces are governed by § 314-109.1.4 (see § 314-109.1.4.1 for single detached/duplex types) .
• ADUs: The County requires one (1) parking space per ADU; that space may be tandem on a driveway and may be located in setbacks in most cases unless specific findings (topographic or fire/life safety) prevent it (§ 314-69.05.4.6) .
• Key caution: State ADU law also applies and can preempt local rules in some circumstances — always cross‑check with state ADU guidance California ADU law.

SRO (Single‑Room Occupancy) Facilities (use‑type specific)

• The SRO development standards require off‑street parking consistent with § 314-109.1 and specifically require secure bicycle parking at the ratio of one (1) space per four (4) SRO units (§ 314-60.1.3.7) .

Checklist (what an applicant must satisfy for an off‑street parking submittal)

• Show on the site plan the number of provided spaces and how they are counted relative to the Code’s parking schedule (§ 314-109.1.4) .
• Locate required spaces on the same parcel or provide documentation/agreements for substitute/shared parking if off‑site (§ 314-109.1.3.1) .
• Provide accessible (handicapped) stalls at the required size and ratio and sign them per Code/County standards (§ 314-109.1.3.8) .
• If loading docks are needed, show required 1 per 20,000 sq ft or request Director/Special Permit approval for exemption (§ 314-109.1.5.1) .
• If proposing fewer spaces than the schedule, attach a parking study or evidence (transit proximity, pedestrian/bicycle connections, shared parking analysis) to support an administrative permit or Special Permit (§ 314-56.5.3; § 314-109.1.3.12) .
• For ADUs, show one dedicated space and explain tandem/setback use if using those options (§ 314-69.05.4.6) .
• Provide landscaping and lighting plans when adding five (5) or more spaces (or as required by the Planning Commission) and comply with visibility corridor rules (§ 314-9.1.1.1; § 314-109.1.6.2) .
• Show secure bicycle parking if a use requires it (for SROs or per local conditions) and reference the County required ratios (§ 314-60.1.3.7) .
• Verify Public Works maneuvering requirements for ≥5 non‑residential spaces (no backing onto the street) (§ 314-109.1.6.1) .

Risks & Ambiguities

Plain‑English Summary

Humboldt County requires most required parking to be provided on site; the off‑street parking chapter sets minimums (including accessible stalls and loading) but also gives tools—administrative permits and Special Permits—to reduce or modify requirements where transit access, site constraints, or shared‑use arrangements make fewer stalls reasonable. ADUs need one space (tandem allowed); loading and bicycle parking minimums are explicitly specified for some uses. Always cross‑check with Public Works and the County planner for site‑specific exceptions or design constraints (§ 314-109.1; § 314-69.05.4.6; § 314-109.1.5) .
