Riverside — Design Review

Last reviewed: July 3, 2026

Overview

The City of Riverside requires design review for many new buildings, exterior alterations, signs, and landscaping in specified zones and specific-plan areas; the detailed procedures live in Chapter 19.710 of the Zoning Code. Design review can be administered as an Administrative Design Review (director/DRC) or heard by the Planning Commission depending on the project and the approving authority; the ordinance lists exempt project types and cross-references site plan, conditional-use and specific-plan reviews. See the City's zoning pages on design and zoning rules for context and the development standards for dimensional rules that the design review enforces.

How design review fits in the code (quick legal anchors)

• Applicability and exemptions: § 19.710.020
• Approval required before starting work: § 19.710.030
• Who reviews/decides (DRC/Director vs Planning Commission): § 19.710.035

District-by-district breakdown

Below are the Riverside districts and specific-plan areas where design review is explicitly required or routinely applied. Each subsection gives the local purpose, typical uses, where design review is required, and the primary code citation.

RC — Residential Conservation (RC)

• Purpose: Preserve and manage design quality around conserved residential areas; informs compatibility of infill and rehabilitations.
• Typical permitted uses: Residential and limited accessory uses as defined by the RC base zone.
• Key dimensional standards: See applicable single‑family / multi‑family development tables in Article V and Chapter 19.100 (development standards vary by subzone).
• Design-review trigger: All new buildings, structures, signs, enlargements and certain site work in the RC zone require design review under § 19.710.020(A)(1).

R-3 and R-4 — Multi‑family residential zones

• Purpose: Medium/high density multi‑family housing.
• Typical uses: Duplexes, apartments, condominiums, accessory uses allowed by the zone.
• Key dimensional standards: Multi‑family standards (height, setbacks, lot coverage) appear in the residential development tables (see Table 19.100.040.A and Chapter 19.100).
• Design-review trigger: In R-3 and R-4 all new buildings, structures or enlargements require design review per § 19.100.080(B) and review is processed under Chapter 19.710.

Commercial & Office — O, CR, CG, CRC

• Purpose: Office, retail, service and general commercial activity (Chapter 19.110 defines intent).
• Typical uses: Administrative offices, retail stores, service providers, and related uses.
• Key dimensional standards: Variable by commercial zone—see Article V Commercial development tables and Chapter 19.110.
• Design-review trigger: Design review applies to new buildings, exterior changes and signage in Commercial and Office zones as listed in § 19.710.020(A)(1).

Mixed‑Use zones (various MU subtypes)

• Purpose: Combine residential with retail/office to create walkable, integrated development.
• Typical uses: Ground‑floor retail with upper‑story housing, stand‑alone multi‑family in certain MU subzones.
• Key dimensional standards: Mixed‑Use development standards and thresholds found in Chapter 19.120 and related tables; certain thresholds trigger site plan review vs design review. See also development standards.
• Design-review trigger: Mixed‑Use projects are included in § 19.710.020(A)(1); stand‑alone multi‑family or age‑restricted senior housing in Mixed‑Use zones may be permitted by right but remain subject to design review under Chapter 19.710.

Industrial zones (I, BMP, Business & Manufacturing Park)

• Purpose: Light to heavy manufacturing, warehousing and industrial services.
• Typical uses: Warehouses, manufacturing, distribution, maintenance/repair.
• Key dimensional standards: Industrial zone tables (e.g., Table 19.145.030 for Railway Zone) set height, setbacks, and lot standards; specific park/warehouse standards in Chapter 19.435.
• Design-review trigger: No industrial building, structure or sign or exterior alteration may commence until design review approval is granted pursuant to § 19.130.050 and Chapter 19.710.

Downtown Specific Plan / Downtown subdistricts

• Purpose: Implement the Downtown Specific Plan’s design and urban form goals.
• Typical uses: Mixed commercial, office, civic and residential uses tailored by subdistrict.
• Key dimensional standards: Adopted Downtown Specific Plan includes subdistrict design guidelines and standards (see Chapter 19.147).
• Design-review trigger: Downtown requires design review for new buildings, signs and exterior alterations as set in the Downtown Specific Plan and Chapter 19.147.050; design guidelines for subdistricts are the primary standard.

Orangecrest Specific Plan Zone — OSP

• Purpose: Create a mixed residential/office/retail area with subdistricts and specific development standards.
• Typical uses: Residential (varied densities), retail and office consistent with the Orangecrest Specific Plan.
• Key dimensional standards: Site development standards are set in the adopted Orangecrest Specific Plan; where conflict exists, the more restrictive standard controls.
• Design-review trigger: The Orangecrest Specific Plan requires design review for any new building, structure or sign per § 19.148.050.

Innovation District Overlay — ID

• Purpose: Encourage high-density, pedestrian‑oriented mixed uses and investment consistent with the ID Master Plan.
• Typical uses: High‑density residential, office, civic, entertainment, institutional and pedestrian retail.
• Key dimensional standards: ID chapter contains project-level design standards; where standards are absent, Title 19 applies.
• Design-review trigger: Projects within the ID Overlay must obtain design review for new construction or exterior alterations per § 19.170.020(C)(1) as implemented through Chapter 19.710.

Checklist (what an applicant must prepare / expect)

• Complete design review application and fees (per Planning Division submittal requirements). Verify with the City. Verify with the jurisdiction.
• Plot plan showing lot lines, building footprint, setbacks and site circulation (site plan review elements may be consolidated) — Chapter 19.770 describes possible required conditions.
• Building elevations and materials/finish/color board for all façades (DRC/Director or Planning Commission will review elevations) — § 19.710.035(A)(1‑2).
• Landscape and irrigation plans (required; Park & Recreation fees due with submittal for landscape review) — § 19.710.035(A)(3).
• Mechanical/outdoor equipment screening details (plan and elevations) — § 19.555.020.
• Trash/recycling enclosure plans consistent with City policies; elevations and construction details — Chapter 19.555 and related trash enclosure policies.
• Sign program or individual sign plans, when signage is proposed (signs reviewed per Citywide Design & Sign Guidelines) — § 19.710.035(A)(2).
• Any required Water Quality Management Plan (WQMP), WQMP compliance or Water Efficient Landscaping and Irrigation documentation (if applicable) — referenced in Administrative Design Review criteria and landscape chapters.
• If your project is in an Overlay (e.g., ID, OSP, Downtown SP), include any specific-plan required graphics, public‑realm improvements or dedication exhibits — see the applicable specific-plan chapter (e.g., § 19.170.020, § 19.148.030, § 19.147.050).

Note: design review does not replace other permits; applicants must still comply with parking standards, signage rules, and development standards. Mechanical and structural code compliance falls under the California Building Standards Code and may be checked separately.

Risks & Ambiguities

Plain‑English summary

If you're planning a non‑trivial exterior change in Riverside — new building, added floor area, new sign, or major landscape/mechanical work — expect to go through the city's design review process (Chapter 19.710) unless your project qualifies for a specific exemption; the review enforces the design guidelines and can be handled administratively by staff or brought to the Planning Commission depending on the project and zone.
