Overview

This page explains how the San Luis Obispo County Land Use Ordinance (Title 22) regulates off-street parking, loading, and related design in the unincorporated areas. Chapter 22.18 establishes the countywide rules for when parking is required, how many spaces are needed by use, how lots are designed and constructed, and when adjustments are possible, with planning-area standards sometimes layering on location-specific tweaks. Title 22 applies inland; sites in the Coastal Zone follow Title 23, but the core framework below reflects inland, unincorporated standards under the County’s zoning and planning overview and Land Use system.

The single most important rule: all uses that require a land use permit must provide off‑street parking consistent with Chapter 22.18, unless specifically modified by that chapter or applicable planning-area standards (§ 22.18.020; § 22.18.050; § 22.01.050) .

Countywide parking and loading standards (what applies everywhere inland)

  • Off-street parking required; available adjustments

    • Parking is required for all permitted uses, with limited modifications for compact spaces, motorcycle spaces, parking districts, on-street-loss offsets, shared on-site parking (up to 20% via adjustment), and shared peak-hour parking via Minor Use Permit (§ 22.18.020.A–F) .
    • “Modification of parking standards” allows further reductions or alternative designs through a Minor Use Permit when findings show needs are met without safety issues (§ 22.18.020.H) .
    • Nonconforming parking can constrain changes of use; see the ordinance pathway referenced by § 22.18.020.G and our page on Nonconforming Uses (§ 22.18.020.G) .

  • Where parking can go on a site

    • No required spaces are allowed in the required front setback, except in Residential Multi-Family areas that qualify for medium- or high-intensity development; side and rear setbacks may be used except the street side of a corner lot (§ 22.18.030.A–B) .

  • Design dimensions and access

    • Standard stall is 9 ft by 18 ft; parallel is 9 ft by 22 ft; aisle widths vary by angle and one-/two-way circulation (§ 22.18.040.A) .
    • Lots with more than two vehicles must be designed to avoid backing into public ways; access must meet § 22.54.020 site access/driveway standards (§ 22.18.040.B.1–2) .
    • Tandem parking is limited to specific cases (same-dwelling tandem, attendant-managed, or restricted all-day employee lots with caps) (§ 22.18.040.B.5) .
    • Required guest spaces for residential projects must be distributed for convenient guest access (§ 22.18.040.B.3, via § 22.18.050.C.5) .

  • Construction, surfacing, and screening

    • Surfacing depends on lot turnover rate and whether you are inside or outside an Urban or Village Reserve Line: asphalt/concrete for higher-intensity inside lines; chip seal/crushed rock may be allowed for lower-intensity and outside lines (§ 22.18.060.A) .
    • Striping, wheel stops/curbs, minimum 7'-6" covered-clearance (non-residential), max 5% slope, and a tree canopy plan to shade 60% of surface within 10 years are required; screening includes perimeter landscape strips and walls/fences toward streets and residential edges (§ 22.18.060.B–G) .

  • Special spaces within Urban or Village Reserve Lines

    • Accessible parking is required in nonresidential lots with five or more spaces and must follow the California Building Standards Code (Title 24); a summary ratio table appears in § 22.18.050.B.1, but design/location is governed by state code (§ 22.18.050.B.1) .
    • Provide one bicycle rack space per 10 auto spaces in lots with 20+ spaces; racks must allow locking (§ 22.18.050.B.3) . (This is separate from CALGreen bicycle requirements.)
    • One space per “company vehicle” parked on-site during normal hours is required for commercial/industrial uses (§ 22.18.050.B.2) .

  • Off-site parking and loading

    • Off-site parking can be approved by adjustment if the farthest space is within 400 ft, under common ownership or recorded lease, and not in a residential category unless the use is allowable there (§ 22.18.070) .
    • Off-street loading bays are required by intensity and floor area; the code provides bay counts by size and “loading intensity” and includes design constraints (access, setbacks from residential, no use for parking) (§ 22.18.080) .

How many spaces? Selected ratios from § 22.18.050

The county uses a by-use schedule that sets required parking, “turnover” (operational intensity), and loading intensity. Below are commonly used entries.

Use (unincorporated areas) Minimum Off-Street Parking Notes Code Reference
Single-family dwellings 2 per dwelling Includes mobile homes on individual lots § 22.18.050.C (Residential Uses)
Multi-family dwellings Residents: 1 per studio/1-bed; 1.5 per 2–3 beds; 2 per 4+ beds; plus Guest: 1 + 1 per each 4 units beyond four Guest spaces must be distributed for access § 22.18.050.C (Residential Uses); § 22.18.040.B.3
General agricultural processing (packing/processing) 1 per 1,000 sf of use area Low turnover; High loading intensity § 22.18.050.C (Agricultural Uses)
Wineries/distilleries 1/2,000 sf active area + 1/5,000 sf storage + 1/200 sf tasting room Low turnover; High loading intensity § 22.18.050.C (Agricultural Uses)
Restaurants & bars (on-site consumption) Customers: 1/60 sf customer area; Employees: 1/360 sf customer area + 1/100 sf kitchen High turnover; Medium loading § 22.18.050.C (Retail Trade Uses)
Fast food 1/100 sf kitchen High turnover; Medium loading § 22.18.050.C (Retail Trade Uses)
Food & beverage retail 1/200 sf floor area + 1/checkstand + 1/600 sf storage High turnover; Medium loading § 22.18.050.C (Retail Trade Uses)
Warehousing (commercial storage) 1/2,000 sf first 10,000 sf; then 1/5,000 sf thereafter Low turnover; High loading § 22.18.050.C (Wholesale Trade)

Notes:

  • Where a building’s exact tenants are unknown, size parking for the most intense allowable use unless uses are limited by recorded agreement or CUP conditions (§ 22.18.050.A.2) .
  • Mixed-use sites add the total of each use, subject to allowed sharing reductions (§ 22.18.020.D–E; § 22.18.050.A.1) .

Planning-area and corridor standards that can change parking outcomes

Several planning-area standards refine where parking sits on a site or how it’s counted. Always check Overlay Districts and community plans:

  • San Miguel (Mission Street): To preserve on-street parking, parcels with alley/side-street access are prohibited from adding driveways on Mission Street; layout guidance urges rear parking and inter-parcel circulation (§ San Miguel standards) .
  • Oceano (Cienaga/21st area): Nonresidential uses that don’t fit “general retail” rates must submit a parking plan; mixed-use projects may need a Minor Use Permit parking adjustment if the plan shows a shortfall (citing § 22.18.020.H) (§ 22.108 standards) .

District-by-district context for parking

San Luis Obispo County uses “land use categories” (e.g., AG, RSF, RMF, CR). Parking requirements are set by use (§ 22.18.050), but district context and planning-area standards affect siting, surfacing, and screening. See Zoning for the county’s category system.

Agriculture (AG)

  • Purpose/context: Working lands with low parking turnover for ag operations; many ag uses rely on on-site usable area.
  • Parking takeaways: Most ag uses either have specific ratios (e.g., packing houses) or can use unimproved on-site areas where allowed; screening applies when abutting residential; surfacing outside Urban/Village lines can be chip seal/crushed rock depending on turnover (§ 22.18.050.C; § 22.18.060.A, G) .
  • Where it applies: Unincorporated rural areas.

Rural Lands (RL)

  • Purpose/context: Low-intensity resource lands; similar parking surfacing flexibility to AG.
  • Parking takeaways: Lower turnover uses may qualify for less intensive surfacing; loading only if required by the use; maintain screening near residences (§ 22.18.060; § 22.18.080) .
  • Where it applies: Unincorporated rural areas.

Residential Rural (RR), Residential Suburban (RS), Residential Single-Family (RSF)

  • Purpose/context: Detached housing categories with varying lot sizes.
  • Parking takeaways: 2 spaces per dwelling for single-family; keep required spaces out of front setbacks; guest distribution rules apply in projects that require guest parking; screening along street/residential edges applies (§ 22.18.050.C; § 22.18.030; § 22.18.040.B.3; § 22.18.060.G) .
  • Where it applies: Unincorporated neighborhoods and rural-residential areas.

Residential Multi-Family (RMF)

  • Purpose/context: Apartments/condos; often medium/high-intensity residential zones.
  • Parking takeaways: Per-unit resident ratios plus distributed guest spaces; limited allowance for required parking in front setbacks for medium/high-intensity RMF; tandem is allowed within a dwelling under limits (§ 22.18.050.C; § 22.18.030.A; § 22.18.040.B.5) .
  • Where it applies: Urbanized unincorporated communities.

Commercial Retail (CR)

  • Purpose/context: Retail, restaurants, visitor-serving uses.
  • Parking takeaways: High-turnover restaurant/food retail ratios; drop-off areas for larger restaurants; frontage design in some corridors may require rear/side parking to support main street character (§ 22.18.050.C; § 22.18.040.B.4; San Miguel standards) .
  • Where it applies: Unincorporated commercial nodes; see planning-area standards.

Commercial Service (CS)

  • Purpose/context: Service, light commercial/industrial hybrids.
  • Parking takeaways: Project-specific rates per § 22.18.050.C tables; business park standards can limit front-lot parking and break large lots into landscaped sub-areas (§ 22.18.050.C; § 22.96 standards excerpts) .
  • Where it applies: Industrial/service corridors in unincorporated areas.

Office & Professional (OP)

  • Purpose/context: Office uses and clinics.
  • Parking takeaways: Size to the applicable office ratio in § 22.18.050.C; provide drop-off areas when over 5,000 sf; bicycle racks if 20+ spaces inside Urban/Village reserve lines (§ 22.18.040.B.4; § 22.18.050.B.3) .
  • Where it applies: Unincorporated office districts.

Industrial (IND)

  • Purpose/context: Manufacturing, warehousing, distribution.
  • Parking takeaways: Lower-turnover employee/long-term parking; robust loading bay requirements based on intensity; warehousing ratios scale with square footage (§ 22.18.050.C; § 22.18.080) .
  • Where it applies: Unincorporated industrial parks.

Recreation (REC)

  • Purpose/context: Private/commercial recreation.
  • Parking takeaways: Recreation-specific ratios (e.g., health resorts/hot springs: 2 per hot tub/spa + 1/100 sf pool, plus lodging unit spaces when included) (§ 22.30 standards) .
  • Where it applies: Unincorporated recreation areas.

Public Facilities (PF) and Open Space (OS)

  • Purpose/context: Civic/institutional and permanent open lands.
  • Parking takeaways: Size to specific institutional use in § 22.18.050.C; provide drop-off for listed public assembly facilities; screening/surfacing apply as elsewhere (§ 22.18.040.B.4; § 22.18.060) .
  • Where it applies: Countywide.

Practical design and compliance notes

  • Landscaping and shading: Parking-lot shade canopy is a development standard; coordinate early with Landscaping and Screening (§ 22.18.060.F–G) .
  • Accessibility: Accessible stall counts and design follow state code referenced by § 22.18.050.B.1; see the California Building Standards Code for technical criteria (Title 24) (§ 22.18.050.B.1) .
  • Bicycle parking: County rack requirement is additive to any CALGreen obligation; confirm the stricter applies for your project (§ 22.18.050.B.3) .
  • ADUs: State law caps ADU parking at 1 per unit/bedroom and exempts many ADUs from parking entirely; guest parking cannot be required for ADUs. See California ADU law (Gov. Code § 66314; HCD 2025 Handbook) for statewide limits that preempt local ratios .

Checklist

  • Identify your land use(s) and applicable category in Title 22; confirm you are in inland, unincorporated County (not Coastal Zone) (§ 22.01.050) .
  • Calculate base parking using § 22.18.050 tables (include resident and guest where applicable) .
  • Check special spaces (accessible per Title 24; bicycle racks if 20+ spaces inside Urban/Village lines; company vehicles) (§ 22.18.050.B.1–3) .
  • Confirm location rules, tandem limits, drop-off needs, and site access (§ 22.18.030; § 22.18.040) .
  • Apply construction/surfacing type by turnover and Urban/Village line; include shading and screening (§ 22.18.060) .
  • Determine if shared parking, on-street-loss adjustment, or off-site parking are sought; collect findings/leases as needed (§ 22.18.020.D–F; § 22.18.070) .
  • Check planning-area/community standards that affect parking layout or counting (e.g., Mission St., Oceano) (planning-area standards) .
  • If seeking reductions, prepare a Minor Use Permit justification addressing § 22.18.020.H findings and any Variances and Exceptions path, if applicable (§ 22.18.020.H) .

Risks & Ambiguities

Issue Why it matters What to verify
Unknown future tenants Parking must cover the most intense likely use if tenants are not known Either limit uses via recorded agreement/CUP or size to the highest required ratio (§ 22.18.050.A.2)
Shared parking claims Reductions have caps, distance limits, and approval types Combine § 22.18.020.D (max 20%) with § 22.18.020.E (peak-hour sharing) and show walk distances to each entrance (§ 22.18.020.D–E)
Off-site parking leases Loss of lease can terminate the use Record lease and track 60‑day replacement window (§ 22.18.070.B)
Surfacing choice Inside/outside Urban/Village lines and turnover change paving type Document turnover and map location; follow § 22.18.060.A table
Guest parking in MF projects Must be distributed for access Lay out guest stalls throughout the site (§ 22.18.040.B.3)
Corridor standards (e.g., Mission St.) Some corridors prohibit new curb cuts to preserve on‑street parking Check applicable planning-area overlays before fixing driveway locations (San Miguel standards)
ADU parking State law overrides local minimums Apply ADU exemptions and 1‑space cap per state law (HCD Handbook)

Plain-English Summary

If you’re building or changing a use in unincorporated San Luis Obispo County, plan on off‑street parking that meets Chapter 22.18: count spaces by the use (homes, shops, restaurants, warehouses each have different ratios), keep required stalls out of front setbacks, and build the lot with the right paving, striping, shading, and screening. You can ask for reductions (shared parking, off-site spaces), but you’ll need findings and, sometimes, a Minor Use Permit; also check any planning-area rules that affect driveways or parking layouts.

Frequently asked questions

How many parking spaces does a single-family house need in unincorporated San Luis Obispo County?

Two off-street spaces per dwelling are required for single-family dwellings on individual lots. Required spaces cannot be placed in the required front setback (§ 22.18.050.C; § 22.18.030.A) .

What are the multi-family parking requirements, including guest spaces?

Resident parking is 1 space per studio/1-bedroom, 1.5 per 2–3 bedrooms, and 2 per 4+ bedrooms, plus guest parking of 1 space plus 1 per each 4 units beyond four. Guest spaces must be distributed for convenient access (§ 22.18.050.C; § 22.18.040.B.3) .

Can I reduce parking by sharing spaces among tenants or with uses that peak at different times?

Yes. Shared on-site parking can reduce counts by 5% per nonresidential use up to 20% by adjustment; additional reduction for differing peak hours requires a Minor Use Permit, with distance and minimum totals controlled by § 22.18.020.D–E (§ 22.18.020.D–E) .

Can required parking go in the front yard setback?

Generally no. Required spaces may not be in the required front setback, except in RMF areas that qualify for medium/high-intensity development. Side and rear setbacks may be used (not the street side on corners) (§ 22.18.030) .

How close must off-site parking be if I can’t fit it on my lot?

Up to 400 feet away, under common ownership or a recorded lease; if a lease ends, you have 60 days to replace the spaces. Off-site parking in residential categories is limited to uses allowable there (§ 22.18.070) .

Do I need bicycle parking?

If your lot has 20 or more spaces within an Urban or Village Reserve Line, provide one rack space per 10 auto spaces. Racks must allow locking (§ 22.18.050.B.3) .

What triggers loading spaces and how are they sized?

Loading bays are required by use and floor area using the “loading intensity” table; they must have direct access and be set back at least 25 ft from residential, and cannot double as parking (§ 22.18.080) .

Is accessible parking part of my minimum count?

Yes. Nonresidential lots with five or more spaces must include accessible stalls per Title 24; counts and technical criteria are in state code referenced by § 22.18.050.B.1 (§ 22.18.050.B.1) .

How does the County treat parking for ADUs?

State law caps ADU parking at one space per unit/bedroom and exempts many ADUs from any parking; guest parking cannot be required for ADUs. Local rules cannot be stricter (Gov. Code § 66314; HCD 2025 ADU Handbook) .

Could planning-area rules change driveway or parking layout?

Yes. For example, San Miguel’s Mission Street prohibits new driveways where alley/side-street access exists to preserve on-street parking; some Oceano blocks require a parking plan for non‑retail uses. Always check applicable standards (§ 22.96 and § 22.108 area standards excerpts) .
