Overview

This page distills how off-street parking, bicycle parking, and loading work under the Sutter County Zoning Code for the unincorporated areas only. The rules live in Article 20 of the County’s Zoning Code and apply to new projects and to changes of use that increase required parking by more than 10% (with some legacy approvals grandfathered) under the broader Sutter County Zoning framework. The County also ties parking lot design and improvements to applicable development standards and, in commercial/industrial settings, often to design review.

Most unincorporated Sutter County projects must provide on-site, usable off‑street parking; you can’t put required spaces in the front or street‑side setbacks, and tandem generally doesn’t count unless specifically allowed. See § 1500-20-030 and § 1500-20-080 for details.

What the ordinance covers

  • Applicability to new development and to changes of use that increase parking by >10% (unincorporated areas) per § 1500-20-020.
  • Location/use rules, off‑site/shared parking, tandem, and multiple parcels per § 1500-20-030.
  • How to calculate minimums, rounding, mixed-use summation, unknown tenants, and parking studies per § 1500-20-040–050.
  • Substitutions (compact, motorcycle, alt‑fuel EV spaces), residential vehicle rules, and ADA cross-reference per § 1500-20-060.
  • Reductions via Administrative Permit and a demand study (shared, unique uses, and TDM programs) per § 1500-20-070.
  • Stall/aisle dimensions, surfacing, striping, access/flow, curb stops, lighting/landscape/screening, and maintenance per § 1500-20-080.
  • Bicycle parking (when and how required) per § 1500-20-090.
  • Loading (when required, dimensions, location/screening, striping, passenger loading) per § 1500-20-100.
  • Related public right‑of‑way dedications/improvements for certain districts and areas per § 1500-20-110.

Core standards and “gotchas”

  • Required parking must remain usable; don’t store fleet vehicles or merchandise there per § 1500-20-030(A).
  • Required spaces may not be placed in front or street-side setbacks (driveways may cross them) per § 1500-20-030(B).
  • Off‑site/shared parking is possible with an Administrative Permit, recorded covenants, and proximity per § 1500-20-030(D) and § 1500-20-070(A).
  • Tandem doesn’t count, except in mobile home parks and for single‑family outside front/side street setbacks with compliant surfacing per § 1500-20-030(E).
  • For multi‑tenant/mixed‑use sites, add the parking required for each use; rounding 0.50 up per § 1500-20-040(A–C).
  • If tenants aren’t known, size parking for the most intense allowed use unless approved otherwise per § 1500-20-040(D).

Bicycle parking essentials

Within a City Sphere of Influence or a Rural Community, provide bicycle spaces in addition to car spaces: multi‑family at 1 per 3 units; schools at 1 per vehicle space; all other uses at 1 per 20 vehicle spaces; racks or lockers are acceptable, and locate near entries, visible, well‑lit, paved, anchored, separated from autos, and maintained per § 1500-20-090(A–B).

Loading areas

Provide at least one loading space (12' x 40' with 14' vertical clearance) for commercial/industrial uses over 10,000 sf, adding one per 20,000 sf to a max of four; place to the rear where feasible, separate from parking aisles, screen with a minimum 6‑foot hedge/fence/wall and landscape, stripe and label; for very large complexes (>50,000 sf), add passenger loading near main entries per § 1500-20-100.

Design of parking lots and spaces

  • Minimum stall/aisle dimensions are in Table 1500‑20‑2; a typical 90° stall is 9 ft x 18 ft with a 27 ft two‑way aisle; compacts: 8 ft x 16 ft. Residential garages must be 10 ft x 20 ft minimum for one car, +10 ft width per added car per § 1500‑20‑080(A).
  • Provide paved surfacing/striping where required; rural/all‑weather options exist outside spheres for certain use types per § 1500‑20‑080(B).
  • Control drainage, safe access/flow, avoid dead‑end aisles (if unavoidable, add 5‑ft backing area), install curb stops and protect sidewalks/landscaping, coordinate lighting/landscaping/screening, and maintain the lot free of weeds/litter per § 1500‑20‑080(C–I).
  • Parking lots are often reviewed with design review in specified districts; County guidance also expects shading of paved parking via trees (e.g., 1 tree per 4 stalls or a 50% shade plan within 15 years) and landscaped islands to break up fields of stalls; see the County’s design/landscape criteria excerpted in the Zoning Code for specifics.

Reductions and flexibility

The County can reduce minimums via an Administrative Permit when justified by a parking demand study for:

  • Shared/mixed‑use projects (aligning peak demands; shared facility within 500 feet; recorded shared‑use covenants) per § 1500‑20‑070(A).
  • Unique operators with different peak profiles per § 1500‑20‑070(B).
  • TDM facilities/programs (e.g., showers/lockers, enhanced secured bike parking, carpool/vanpool priority, proximity to transit) per § 1500‑20‑070(C).

Standalone “Parking Facilities” are recognized as a use type in the County’s Use Tables and appear broadly permitted in several districts; when a parcel is used solely for parking, Table 1500‑20‑1 indicates “none beyond parking facility itself” for required spaces per § 1500‑20‑050/Table 1500‑20‑1 and the Use Tables excerpt in Article 7.

Residential nuances (vehicles, RVs, setbacks)

  • Inoperable/unregistered vehicles, trailers, and boats must be behind a 6‑ft fence or inside an enclosed structure; not in required front/street‑side yards in residential districts per § 1500‑20‑060(F)(1).
  • Commercial truck‑tractor/trailer parking is prohibited on residential parcels, with limited exceptions in ER, RAN, and R‑1 via Use Permit per § 1500‑20‑060(F)(2).
  • RV/boat parking: within a City Sphere/Rural Community, RV/boat parking is prohibited in required front/street‑side setbacks; outside those areas, one licensed RV/boat may be stored in an unscreened front/side street setback on parcels zoned AG, RAN, ER, R‑1 if it’s in a designated surfaced area and outside rights‑of‑way/easements per § 1500‑20‑060(F)(3).

Title 24/ADA parking

Accessible parking counts, location, striping, and signage reference state and federal accessibility rules; the County points to the California Building Standards Code and federal guidelines. Accessible stalls count toward your minimums per § 1500‑20‑060(A).

  • A -PD overlay may modify minimum off‑street parking ratios when the Board of Supervisors establishes the PD standards; check adopted Development Plans per § 1500‑08‑060(D)(7). See Sutter County Overlay Districts.

Checklist

  • Confirm your parcel is in the unincorporated county (not an incorporated city) via the Sutter County zoning & planning overview.
  • Identify your base district and any overlays; if within a -PD, verify any modified parking ratios per § 1500‑08‑060(D).
  • Calculate minimum off‑street parking using Table 1500‑20‑1; apply rounding and mixed‑use rules per § 1500‑20‑040.
  • Check if bicycle parking is required (spheres/Rural Communities) and design per § 1500‑20‑090.
  • Provide loading spaces if floor area and use type trigger them per § 1500‑20‑100.
  • Site spaces outside front/street‑side setbacks; avoid tandem unless allowed per § 1500‑20‑030.
  • Design stalls/aisles to Table 1500‑20‑2; pave/stripe/surface appropriately and address access, drainage, lighting, landscaping, screening per § 1500‑20‑080 and County landscape criteria.
  • If seeking reductions or shared parking, prepare a demand study and record agreements per § 1500‑20‑070.
  • If in Commercial/Employment districts or Sutter Pointe, be ready for frontage improvements tied to occupancy/parking-demand increases per § 1500‑20‑110.
  • If the project triggers design review, incorporate Article 20 compliance and the County’s parking/landscape expectations.

Plain-English Summary

In unincorporated Sutter County, you must provide usable off‑street parking on your site. The County spells out how to count spaces, where to put them (not in front setbacks), how big they must be, what surfacing is required (paved in commercial/industrial and many urbanized contexts), when to add bike parking and loading, and when you can share or reduce spaces with a study. If you are near a city sphere or in commercial/industrial districts, expect paving, possible frontage improvements, and design review scrutiny of your lot layout.

Frequently asked questions

Can I put required parking in my front setback in unincorporated Sutter County?

No. Required off‑street spaces cannot be located in front or street‑side setbacks. Driveways may cross those setbacks to reach parking areas, but the spaces themselves must be outside the setbacks per § 1500‑20‑030(B).

Are tandem spaces allowed to count toward my minimum parking?

Generally no. Tandem stalls do not count toward the minimums, except in mobile home parks and for single‑family residential when the tandem spaces are outside required front/street‑side setbacks and properly surfaced per § 1500‑20‑030(E).

How close must shared or off‑site parking be to my use?

Shared parking for mixed/joint‑use projects must be within about 500 feet and backed by recorded covenants. An Administrative Permit and a parking demand study are required for reductions per § 1500‑20‑070(A)(3–4).

When are loading spaces required, and how big are they?

Commercial and industrial uses over 10,000 square feet that require loading must provide at least one loading space, plus one per additional 20,000 square feet up to four. Each loading space must be at least 12' wide by 40' long with 14' vertical clearance; location/screening rules also apply per § 1500‑20‑100.

Do I need to provide bicycle parking?

Yes, in City Spheres of Influence and Rural Communities. Provide 1 bike space per 3 units (multi‑family), 1 per vehicle space (schools), and 1 per 20 vehicle spaces (all others); locate near entries, paved, visible, anchored, and separated from vehicles per § 1500‑20‑090.

What are the standard stall and aisle dimensions?

A typical full‑size stall is 9 ft by 18 ft; a 90‑degree two‑way aisle is 27 ft. Compact stalls are 8 ft by 16 ft. Residential garages must be at least 10 ft by 20 ft for one car (wider for more cars) per § 1500‑20‑080(A).

Can I reduce my required parking with a transportation demand program?

Possibly. The County may approve reductions when a study shows carpool/vanpool incentives, showers/lockers for cyclists, enhanced bike parking, or proximity to active transit will lower demand. Recording conditions to maintain the program is required per § 1500‑20‑070(C).

Can I store an RV or a boat in my front yard?

It depends on where you are and your zoning. Within City Spheres/Rural Communities, RV/boat storage is prohibited in required front/street‑side yards. Outside those areas, one licensed RV/boat may be stored in the front/side street setback on AG, RAN, ER, or R‑1 parcels if on a compliant surfaced area and outside ROW/easements per § 1500‑20‑060(F)(3).

Do I have to pave my parking lot in agricultural or rural areas?

Often not. Outside City Spheres/Rural Communities, certain agricultural, open space, resource extraction, and residential use types may use all‑weather surfacing (e.g., 4 inches of Class 2 aggregate base) instead of paving, unless conditioned otherwise per § 1500‑20‑080(B)(2).

If my tenant changes, do I need more parking?

If the change increases the number of required off‑street spaces by more than 10%, you must add spaces to meet the added demand per § 1500‑20‑020(B). For unknown tenants at shell approval, the County may require parking sized to the most intense allowed use per § 1500‑20‑040(D).
