Riverside — Parking

Q: What are the minimum parking stall and aisle dimensions I must show on plans?

Minimum stall sizes are 9 ft × 18 ft for standard stalls and 8 ft × 16 ft for compact stalls (compact limited to 15% of total); drive‑aisle widths are set in Table 19.580.080 B and driveway minimums in Table 19.580.080 C — see § 19.580.080 .

Q: Can a mixed‑use project reduce required parking near transit?

Yes. The Director may grant a mixed‑use parking credit up to 15% for developments within a Transit Priority Area or supported by a shared‑parking analysis; VMT‑reduction incentives can also reduce parking up to 10% , and both can combine subject to limits — see § 19.580.060 C–D .

Q: What are Riverside's off‑street loading requirements for new commercial/industrial buildings?

At least one loading space of 10 ft × 22 ft × 14 ft (H) per 4,000 sq ft gross floor area (with a limit of two spaces required unless the floor area exceeds 20,000 sq ft) and associated maneuvering area must be provided — see § 19.580.110 .

Q: What landscaping is required inside and around parking lots?

Parking lots must include shade and screening: roughly one tree per four spaces , minimum percent coverage rules (parking lots >20 spaces require minimum 5% of lot area landscaped), and street‑front landscaped setbacks (10–15 ft depending on size); see § 19.580.090 for full rules.

Overview

This page explains what the City of Riverside's zoning code requires for parking, loading, and associated design/maintenance rules under the local zoning ordinance (primarily Chapter 19.580). It focuses only on zoning/planning requirements (off-street parking counts, stall dimensions, landscaping, loading, special district exceptions and credits) and does not cover Title 24 building-code or tenant/housing law. See the city's rules for design and permitting interactions with design review and development standards below. § 19.580.010 sets the purpose and scope of the chapter.

Controlling chapters & top-line rules

Purpose and applicability: Chapter 19.580 (Parking and Loading) — § 19.580.010 (purpose) and § 19.580.020 (applicability) establish that off‑street parking and loading requirements apply to new and existing development and to off‑street lots even when not otherwise required by title.
Minimum parking counts: Table 19.580.060 sets minimum required off‑street spaces per use; the table is the starting point for almost every calculation. § 19.580.060 describes mixed‑use credits, VMT incentives, and exceptions.
Design/dimension standards: Stall sizes, compact-space limits, aisle widths, driveway widths, garage dimensions and tandem rules are in § 19.580.080 and its tables.
Loading: Off‑street loading minimums and maneuvering requirements are in § 19.580.110.
Landscaping / screening: Parking-lot landscaping, setbacks and screening are in § 19.580.090.
Maintenance & enforcement: Long‑term maintenance and enforcement rules are in § 19.580.120 and § 19.580.130.

District-by-district breakdown (Riverside-specific)

Below are the most decision‑relevant Riverside zoning districts with what the zoning code actually ties to parking. This is a plain‑English synthesis tied to the local code citations shown.

R-1 (Single‑Family Residential)

Purpose / typical uses: Single‑family homes and accessory uses listed in the residential tables. Parking normally follows the base Table 19.580.060 and the residential use rows of that table.
Key parking rules:
- On‑lot parking must follow the off‑street location/type rules; front/street‑side yard landscaping generally may not be used for parking — see § 19.580.050 H and references to 19.580.070 for permitted locations (full 19.580.070 text not fully reproduced in retrieved materials; verify with the City).
- Single‑family garage minimum interior sizes are specified in § 19.580.080 (one‑car 12'×20', two‑car 20'×20').
- Special overlay or site rules may add requirements (e.g., Residential Protection Overlay applies additional development standards that reference Chapter 19.580).
Where it applies: City neighborhoods zoned R-1; parking specifics for accessory dwellings and two‑unit developments are handled elsewhere (see ADU rules). (Verify with the jurisdiction for parcel‑specific driveway/front‑yard interpretations.)

R-3 / Multiple‑Family Residential

Purpose / typical uses: Multi‑unit apartments, townhomes and small lot developments. Parking counts are taken from Table 19.580.060 under "Dwelling – Multiple Family."
Key parking rules:
- At least 75% of the required multifamily parking must be covered (carport or enclosed) unless otherwise modified — § 19.580. (multiple family rules)*. Tandem parking may be allowed in limited cases for units with two or more bedrooms — § 19.580.070 cross‑references.
- Small‑lot PRD projects must follow Chapter 19.780 and provide parking in accordance with Chapter 19.580; recreational vehicle parking is prohibited on residential lots.
Where it applies: All R-3 zoned areas; PRD exceptions apply where a PRD permit is granted — Chapter 19.780.

RC (Residential Conservation) and PRD (Planned Residential Developments)

Purpose / typical uses: Special residential conservation / planned development types with site‑specific standards.
Key parking rules:
- PRD projects generally require two fully enclosed spaces per dwelling unit and guest parking (often 1 guest per 3 units) — these are exceptions/additions to Chapter 19.580 and appear in the PRD sections. § 19.780 and associated subsections apply.
- PRD projects must still design parking to meet Chapter 19.580 dimensional standards.

MU‑N, MU‑V, MU‑U (Mixed‑Use: Neighborhood / Village / Urban)

Purpose / typical uses: Ground‑floor retail/office with residential above in different urban intensities.
Key parking rules:
- Mixed‑use zones refer parking to Chapter 19.580 for counts and allow design flexibility; parking structures must be integrated with architecture and parking between the street and buildings is prohibited — § 19.170.070 (mixed‑use standards) with cross‑references to § 19.580.060.
- Mixed‑use parking credit: the Community & Economic Development Director may grant up to a 15% mixed‑use parking credit where transit‑priority conditions or a shared‑parking analysis justify a reduction — § 19.580.060 C.

C‑P / C‑1 / Commercial Zones

Purpose / typical uses: Office and neighborhood retail; parking demand typically higher per square foot.
Key parking rules:
- Use‑specific ratios are in Table 19.580.060 (for example, offices are commonly 1 space/250 sf). See the table for the precise entry for each commercial use; the approving authority can require more spaces at discretionary review. § 19.580.060 E and Table 19.580.060.
- Drive‑throughs, outdoor sales, and other special commercial uses have separate footnotes and may have modified or mixed classifications in the table.

M‑1 / Industrial Zones

Purpose / typical uses: Manufacturing, processing, distribution.
Key parking & loading rules:
- Parking areas for industrial uses are provided per Chapter 19.580; when industrial uses abut residential zones additional landscape buffers and screening (e.g., 20‑ft buffer) apply — see industrial zone chapter cross‑references plus § 19.580.
- Loading: At least one loading space of 10 ft × 22 ft × 14 ft (H) per 4,000 sf gross floor area (with limits on how many required) is specified in § 19.580.110.

Key numeric standards (decision‑relevant table)

Standard / topic	Requirement (plain English)	Code reference

Distance to off‑site parking	When allowed, parking may be provided within 300 ft walking distance unless otherwise stated	Table notes in Table 19.580.060 and § 19.580.060 E.

Practical guidance & interpretation tips

Always start with Table 19.580.060 for counts. If the exact use is not listed, the Community & Economic Development Director will determine a ratio (see § 19.580.060 B).
If you propose a mixed‑use project near transit, plan a shared‑parking analysis to pursue the 15% credit and/or VMT measures for further reductions; document trip patterns, hours and peak demands (see § 19.580.060 C–D).
Dimension checks matter: if you propose angled stalls or compact stalls, overlay the standard rectangle per § 19.580.080 A.7 to demonstrate no overhang into drive aisles or planters.
Multifamily projects should budget for covered parking (75% covered requirement) and account for distribution and landscaping between garage structures per the multifamily subsection.
Loading and maneuvering areas are part of the parking plan and must meet the same design, surfacing and access standards as parking (see § 19.580.110 and § 19.580.040 for plot‑plan requirements). file
Landscaping and setbacks for parking are mandatory; parking between the public right‑of‑way and buildings is generally prohibited in mixed‑use zones (see § 19.580.090 and mixed‑use standards). file

Checklist

Consult Table 19.580.060 and identify the exact row for your use § 19.580.060.
Prepare a plot plan showing location, counts, stall dimensions, aisle widths, curb cuts, landscaping and lighting (required before building permit) § 19.580.040.
Verify stall dimensions, compact‑space percentage, driveway/aisle widths per § 19.580.080 and include dimension callouts.
Provide required loading spaces per § 19.580.110 if the use involves materials/merchandise.
Show parking‑lot landscaping, street setbacks and tree counts on landscape plan per § 19.580.090.
If seeking reductions (mixed‑use credit, VMT incentive, ADU exemptions), submit supporting analyses (shared parking study, VMT measures). § 19.580.060.
Confirm covered parking percentage and guest‑parking rules if project is multi‑family or a PRD — Chapter 19.780.

Risks & Ambiguities

Issue	Why it matters	What to verify
Unlisted or novel use	Table 19.580.060 may not have a direct row; the Director sets a ratio	Ask the Community & Economic Development Director for a formal determination § 19.580.060 B.
19.580.070 location/type specifics	Several sections reference § 19.580.070 for where parking may be located but the full text was not included in retrieved excerpts	Verify the full text of § 19.580.070 with the City (parcel‑specific driveway/front‑yard questions). Not found in retrieved materials.
Historic properties	Historic resource exemptions may relieve parking additions but standards vary	Confirm application of the cultural resources parking exemption in § 19.580.060 F and consult Historic Preservation rules.
ADU parking interplay	State ADU laws may preempt some local parking rules; local code cross‑references ADUs in other chapters	Check local ADU chapter and California ADU law; local code references ADUs but parcel outcomes can vary. Verify with the City.
Compact/tandem allowances	Compact stalls limited to 15% and tandem generally disallowed except where specifically allowed	Confirm proposed compact/tandem usage meets § 19.580.080 and any zone‑level exceptions.

Plain‑English summary

Riverside's zoning code requires you to provide a specific number of off‑street parking spaces for almost every use (start at Table 19.580.060), with detailed stall sizes, aisle widths, landscaping, and loading bay rules set out in § 19.580.080–§ 19.580.110; mixed‑use projects and VMT‑reducing measures can earn moderate reductions, but multi‑family developments must plan for covered parking and tree/landscape requirements. file

Frequently asked questions

What table sets the required number of off‑street parking spaces in Riverside?

The required number of spaces for most uses is set in Table 19.580.060 (Required Spaces); start there for your use and follow the rules in § 19.580.060 for mixed‑use credits and exceptions.

What are the minimum parking stall and aisle dimensions I must show on plans?

Minimum stall sizes are 9 ft × 18 ft for standard stalls and 8 ft × 16 ft for compact stalls (compact limited to 15% of total); drive‑aisle widths are set in Table 19.580.080 B and driveway minimums in Table 19.580.080 C — see § 19.580.080.

Can a mixed‑use project reduce required parking near transit?

Yes. The Director may grant a mixed‑use parking credit up to 15% for developments within a Transit Priority Area or supported by a shared‑parking analysis; VMT‑reduction incentives can also reduce parking up to 10%, and both can combine subject to limits — see § 19.580.060 C–D.

Do multifamily projects need covered parking?

Multifamily developments must provide covered parking for a high portion of required spaces — the code requires at least 75% of required multifamily parking be in a carport or fully enclosed structure (see multifamily provisions referencing Chapter 19.580).

What are Riverside's off‑street loading requirements for new commercial/industrial buildings?

At least one loading space of 10 ft × 22 ft × 14 ft (H) per 4,000 sq ft gross floor area (with a limit of two spaces required unless the floor area exceeds 20,000 sq ft) and associated maneuvering area must be provided — see § 19.580.110.

Can parking be located off‑site?

Yes, in some cases parking may be located off‑site within a specified walking distance (300 ft is used in Table notes), but the exact allowances and measurement rules are in Table 19.580.060 and its notes; verify with the Community & Economic Development Director. § 19.580.060 E.

Are compact and tandem spaces accepted for single‑family homes?

Compact spaces are not permitted to satisfy single‑family requirements (compact limits are described in § 19.580.080). Tandem parking generally cannot satisfy minimums except for certain multifamily or specific single‑family exceptions listed in § 19.580.070 and zone subsections; check the applicable subsection for your zone.

What landscaping is required inside and around parking lots?

Parking lots must include shade and screening: roughly one tree per four spaces, minimum percent coverage rules (parking lots >20 spaces require minimum 5% of lot area landscaped), and street‑front landscaped setbacks (10–15 ft depending on size); see § 19.580.090 for full rules.

If my proposed use is not listed in the table, who sets the parking ratio?

If not listed, the Community & Economic Development Director (or designee) determines the required number based on similar uses and operating characteristics per § 19.580.060 B.

Does Riverside prohibit large commercial truck parking in residential zones?

Yes. It is unlawful to park trucks or trailers over certain sizes (GVWR >10,000 lb or larger than 8 ft high/24 ft long) on residentially zoned property except for immediate loading/unloading or as otherwise allowed; see the prohibition language in § 19.580.100.
