Redwood City — Design Review

Last reviewed: July 2, 2026

Overview

Design review in Redwood City is processed primarily through the Architectural Permit (often called "design review" in practice). The Architectural Permit regulates appearance, site layout, and compatibility — applying to most nonresidential projects and specified residential projects — and relies on findings about neighborhood character, landscaping, parking access, and architectural quality. The permit rules, review authorities, required findings, and thresholds are set in the city's Zoning Ordinance (Article 45 and related articles) and are applied together with the city's development standards (setbacks, height, facade rules, landscaping, and overlay-specific rules). See the city's Zoning overview for context at the Redwood City Zoning page. (/us/california/redwood-city/zoning)

Important first links (used at first natural mention below): this page cross-refers to the city's rules for parking, development standards, overlay districts, Historic Preservation, landscaping, ADUs, and the California Building Standards Code for later building-permit work — link targets are the Redwood City menus listed above: Parking (/us/california/redwood-city/parking); Development Standards (/us/california/redwood-city/development-standards); Overlay Districts (/us/california/redwood-city/overlay-districts); Historic Preservation (/us/california/redwood-city/historic-preservation); Landscaping and Screening (/us/california/redwood-city/landscaping-and-screening); ADUs (/us/california/redwood-city/adu); California Building Standards Code (/us/california/building-codes).

Note: this page summarizes the Zoning Ordinance design-review rules (Architectural Permits and closely related permit types). It does not cover building-code (Title 24) compliance, ministerial building permits, or tenant/housing law.

What the Zoning Ordinance actually says (core rules)

• Permit type: Redwood City calls the design-review process an Architectural Permit. The purpose, applicability, and procedure are located in Article 45 of the Zoning Ordinance (see § 45.1–§ 45.6) — the city defines the permit to "provide for the orderly and harmonious appearance of structure and related site improvements" and to "ensure the design quality of developments" (§ 45.1) .

• Applicability: The ordinance says the following projects require an Architectural Permit: new construction, additions or exterior changes for nonresidential uses and specified residential projects (the code lists applicability categories and expressly excludes SB 9 projects from Architectural Permit review in Article 45) (§ 45.2) .

• Review authority and public hearing thresholds: The Zoning Administrator typically decides Architectural Permits without a public hearing, except where the code requires otherwise — for example, large single-family projects or projects on steep/sloping lots trigger public hearings (see § 45.3; single-family projects exceeding 3,000 sq ft or certain FAR thresholds require Planning Commission hearing per Article 48) .

• Required findings: The Architectural Permit decision must be supported by design-oriented findings: variety in design, proportionality and harmony with the site, conformity to the character of nearby structures, retention of natural features, parking accessibility, landscaping and screening standards, and special findings for sloping lots (§ 45.4; § 45.5 for sloping-lot additional findings) .

• Procedure and appeals: Common procedures (notice, decision types, appeal rights, permit duration) are handled in Article 41 (Article 41.5 public notice; Article 41.6 decisions and permit effectiveness) — decisions may approve, deny, amend, revoke, or condition permits (§ 41.5–§ 41.6) .

• Design standards that review relies on: Architectural Permits are applied together with the city's development and design standards (setbacks, facade/opening composition, landscaping, screening, sidewalks, parking). Examples include façade glazing minimums for street-facing faces in several subareas (e.g., 40% ground-floor commercial glazing in mixed-use/commercial contexts per § 17A.5/§ 53.8), landscaping and pervious-area minimums, and mechanical screening requirements (§ 17A.5; § 53.5; § 55.5) .

• Planned developments: When a project is processed as a Planned Development or Planned Community permit, the review authority may modify development standards but must still approve design-related findings; Planned Development standards and findings are in Article 46 (§ 46.4–§ 46.6) .

• Overlay and sub-district rules: The city applies sub-district/floating standards (for example, MUC sub-districts) that add specific façade, entrance, sidewalk, height/FAR, and public-space expectations that the review authority enforces as part of design review (see Table 53-3 and related text in Article 53) .

District-by-district breakdown (how design review functions by district)

Below are the primary districts that commonly trigger Architectural Permits and the local rules that most affect design review. Each subsection summarizes purpose, typical uses, key dimensional/design standards that the Architectural Permit enforces, and where the district commonly applies.

R-1 (Residential — Single Family)

• Purpose: promotes low-density detached single-family living and accessory uses (§ 5.1) .
• Typical permitted uses: detached single-family homes, accessory buildings and ADUs (subject to Article 37 rules), customary residential accessory uses (§ 5.1) .
• Key dimensional/design standards (that design review enforces): front setback 15 ft (garage/carport 20 ft); side setbacks (interior first story minimum 6 ft, exterior side yard adjacent to street 12.5–15 ft depending on lot width); rear setback 20 ft; max height 28 ft / 2.5 stories; lot coverage 40%; pervious area minimums (40% lot; 60% of front yard on sloping R-1 lots per Article 5) — see §§ 5.6, 5.7, 5.5, 5.9 .
• Where it applies: predominant western and flatter parts of the city; sloping lot rules and "sloping lots" definition also address hillside R-1 properties (§ 5.8) .

RH (Residential — Hillside)

• Purpose: hillside/residential with larger lots, semi‑rural character (§ 5.1) .
• Typical permitted uses: single-family homes, accessory uses, and site-sensitive development (§ 5.1) .
• Key dimensional/design standards: front setback 20–25 ft (depending on lot area), side yard requirements with first-story/upper-story distinctions (first story: 7 ft on one side, total 15 ft for both sides), rear setback 25 ft; lot width and minimum site-size rules; additional sloping-lot findings and construction measures (§ 5.7, § 5.8) .
• Where it applies: hillside areas and areas identified by the code as RH (§ 5.1) .

MUC (Mixed-Use Corridor / sub-districts — MUC‑ECR, MUC‑VB, MUC‑RC, MUC‑SB, MUC‑GB)

• Purpose: mixed‑use urban corridor standards with sub-district specificity (El Camino Real, Veterans Blvd, Redwood Creek, Seaport/Station Block, Gateway) used to shape higher-intensity, pedestrian-oriented development (§ 53.x) .
• Typical permitted uses: mixed commercial/residential, retail, office, and residential at higher densities; ground-floor active uses emphasized (§ 53.8, Table 53-3) .
• Key dimensional/design standards that Architectural Permit enforces: maximum building heights (typical example 85 ft with bonus rules), minimum street-facing façade transparency and entrance frequency, sidewalk widths, minimum pervious area, FAR and possible FAR bonus rules, and sub-district-specific pedestrian entrance frequency (e.g., ground-related entrances every 100 ft or 50 ft for retail) (§ 53.7; Table 53-3; § 53.8; § 17A.5 for façade composition) .
• Where it applies: specific mixed-use zoning sub-districts mapped in the Zoning Map (El Camino Real corridor, downtown and gateway areas) — these sub-district standards are applied during Architectural Permit review as objective and/or discretionary criteria (§ 53.x) .

IP (Industrial Park)

• Purpose and typical uses: industrial/office park uses with design expectations to minimize impacts on adjacent residential areas and require screening, loading and service area design (§ 18 / Article 18) .
• Key standards: setback and upper-story stepback rules, screening of service areas and mechanical equipment, and façade/opening standards that review authority will consider (§ 55.5; Article 18 design rules) .
• Where it applies: industrial park zones shown on the zoning map; Architectural Permits for nonresidential buildings in IP districts are subject to Article 45 findings (§ 45.2–45.4) .

Checklist — what an applicant must satisfy (practical)

• Identify whether an Architectural Permit is required (nonresidential work and many residential exterior projects) — verify applicability under § 45.2 .
• Prepare design drawings showing building massing, elevations, materials, and façades demonstrating compliance with façade composition requirements (e.g., glazing percentages where applicable) — refer to § 17A.5 and § 53.8 .
• Submit a landscape plan integrated with the site layout showing pervious area, street trees, and screening of service/mechanical areas — see § 53.5 and § 55.5 .
• Demonstrate parking access and layout compliance with Article 30 (Off‑Street Parking & Loading) and show pedestrian connections to the public sidewalk — see § 45.4 (findings re: parking) and Article 30 (parking) .
• If the project is large or on a sloping lot, include special analyses (grading, slope stability, context setbacks, additional findings per sloping-lot rules) — see § 45.5 and § 5.8 .
• If you are in an overlay/sub-district (e.g., MUC-ECR, MUC-VB), include sub‑district-specific design responses: entrance frequency, sidewalk treatment, and any required public amenities — see Article 53 sub-district rules (§ 53.5–§ 53.8) .
• Confirm public-noticing requirements and anticipated review authority (ZA, Planning Commission) per Article 41 (public notice, decision types) — see § 41.5–§ 41.6 .
• Prepare to show how the project meets the Architectural Permit findings in § 45.4 (written narrative tying design choices to the findings) .

Risks & Ambiguities

Plain‑English summary

If you are changing a building’s exterior or building new nonresidential (or certain residential) work in Redwood City, you will very likely need an Architectural Permit — the city’s design-review process — which evaluates how your building looks, how it connects to sidewalks and parking, and how landscaping and mechanical equipment are screened. The city’s design findings and numeric standards (setbacks, heights, glazing, pervious area, and sub-district rules) are what the planner or Zoning Administrator will use to approve, condition, or deny your project; always check the specific sections cited below and verify thresholds with city staff.
