Garden Grove — Design Review

Last reviewed: July 2, 2026

Overview

Garden Grove’s local rules for design review are embedded in the City’s Land Use Code (Title 9). The code assigns review authority (Director, Zoning Administrator, Planning Commission, Downtown Commission, and City Council) and ties design and architectural review to specific zone chapters (especially the Civic Center CC zones and Garden Grove Boulevard Mixed Use GGMU zones) and to the site‑plan / discretionary permit procedures in Chapter 9.32. The rules require conformance with adopted architectural/design criteria and with site, landscaping and sign standards; thresholds and the hearing body depend on the zone and the permit type (§ 9.04.030; § 9.18.090.030; § 9.18.100; § 9.32.010.H).

Other related pages referenced below include Garden Grove Parking, Garden Grove Overlay Districts, Garden Grove ADUs, Garden Grove Signage, Garden Grove Landscaping and Screening, and the California Building Standards Code.)

How Garden Grove organizes design/architectural review (short primer)

• Review authorities are established in the code: Planning Commission, City Manager/Director, and Zoning Administrator have explicit roles in design-related decisions; a Planning Coordinating Committee provides technical review and the City Council is the final appeal body (§ 9.04.030).
• The procedures and thresholds for hearings, site plan approvals and appeals are consolidated in Chapter 9.32 (procedures/hearings); design guidelines are specifically a matter the hearing body reviews and adopts by resolution (§ 9.32.010.H; § 9.32.020).
• Many zone chapters (notably the Civic Center (CC) and Garden Grove Boulevard Mixed Use (GGMU) chapters) add mandatory site‑plan and building design plan steps and identify which commissions review architecture (for example the Downtown Commission in CC‑2) (§ 9.18.090.030.D).

District-by-district summary (purpose, typical uses, key dimensional/design triggers, where it applies)

Note: the code defines zones in § 9.04.050; each district’s design rules (when present) are in the chapter cited below.

R-1 — Single-Family Residential

• Purpose: regulate single‑family development and preserve neighborhood character. (§ 9.04.050)
• Typical permitted uses: detached single-family dwellings (and accessory structures). (See Chapter 9.08 for R‑1 standards.)
• Key dimensional/design standards: refer to Chapter 9.08 (R‑1 standards) for setbacks, heights, minimum unit area and intrusions; single‑family work is generally regulated by those objective standards (§ 9.12.040.030 references R‑1 standards for single‑family construction in R‑2/R‑3).
• Design review triggers: the code does not publish a universal “design review required for all R‑1 projects” rule in the retrieved excerpts; instead single‑family projects must meet R‑1 objective standards (see Chapter 9.08) and may be subject to discretionary review when a hearing‑body action is required (e.g., variances). Verify with staff for neighborhood/design‑review thresholds. Not found in retrieved materials for a blanket R‑1 design review trigger.

R-2 / R-3 — Multi‑Family Residential and Limited Multi

• Purpose & uses: duplexes, triplexes and multifamily units; R‑2/R‑3 projects must comply with R‑1 single‑family standards where noted; special rules for duplex/triplex are in § 9.12.040.040.
• Key standards: e.g., maximum main structure two stories/30 ft for duplex/triplex; lot coverage caps (50% for duplex/triplex); minimum lot width for new duplex/triplex 60 ft (§ 9.12.040.040).
• Design review: larger multi‑unit projects often enter discretionary review (site plan, PUD, or ministerial housing review per Chapter 9.32). For state‑ministerial housing projects, the Department Director may perform ministerial review subject to objective standards (§ 9.32.010.D).

O-P, C-1, C-2, C-3 — Office & Commercial Zones

• Purpose & uses: office, neighborhood and community commercial uses (listed in each base zone); see § 9.04.050 for zone names.
• Key design/dimensional rules: commercial/office development standards and tables (setbacks, heights, lot dimensions) live in § 9.16.040 and related tables (see § 9.16.040.010). Large commercial changes or sign relocations are processed through Site Plan (Planning Commission) per the listed procedures (e.g., billboard relocation example) (§ 9.20.110).
• Design review triggers: site plan/site design review is common for new commercial buildings or substantial expansion; signage and parking design are specifically regulated and can be conditioned through site plan approvals (§ 9.20; § 9.18.*).

M-1 / M-P — Industrial / Industrial Park

• Purpose & uses: light industrial, manufacturing, industrial park uses; development standards and design expectations for service, screening and circulation are in the commercial/industrial chapters (see § 9.16.040).
• Design review triggers: redevelopment or new industrial buildings typically go through site plan and technical review by the Planning Coordinating Committee and may require discretionary hearings depending on the application (§ 9.04.030; § 9.32).

GGMU‑1 / GGMU‑2 / GGMU‑3 — Garden Grove Boulevard Mixed Use

• Purpose: create a pedestrian‑oriented, boulevard character with active frontages and higher intensity where appropriate; three intensity tiers are GGMU‑1, GGMU‑2, GGMU‑3 (§ 9.18.010.020; § 9.18.100).
• Typical uses: integrated commercial and residential mixed‑use, plazas, retail at ground floor, pedestrian amenities.
• Key standards and design triggers: specific front‑setback/pedestrian plaza/tree requirements; boulevard garden plaza sizes (Table 9.18‑3) and mandatory plaza/landscaping standards; enhanced building design standards and site design standards apply to all GGMU zones (§ 9.18.100.020; Table 9.18‑3).

CC‑1 / CC‑2 / CC‑3 / CC‑OS — Civic Center zones

• Purpose: mix of civic, institutional, commercial and high‑density residential uses; Main Street historic character (especially CC‑2) is emphasized. (§ 9.18.090.030).
• Typical uses: civic, retail, mixed‑use, plazas and shared parking solutions.
• Key design triggers: site plan mandatory before building permits where a new building is proposed or floor area >10% added; building design plan required for structural rehab when a site plan is not required; Downtown Commission reviews plans and recommends to the Planning Commission; projects must conform to architectural/design criteria adopted by the Community Development Department (§ 9.18.090.030.D.1–4).

Historical‑Cultural Overlay (HC)

• Purpose & application: preserves historic/cultural resources; the overlay is combined with base zones and imposes additional review (site plan approval required prior to building permits in the overlay area). (§ 9.16.030.030).
• Design review: the overlay explicitly empowers the Zoning Administrator and hearing bodies to review improvements and requires that future improvements within 200 ft be approved by the Zoning Administrator for compatibility. (§ 9.16.030.030.D–E).

Transition Overlay (T) and other Specific/Planned zones

• Purpose: facilitate transitions and special design criteria between uses; they set additional lot and design standards and may require site plan/Planning Commission review; see overlay chapters (e.g., Transition Overlay § 9.28/9.18 references).

Quick reference table — most decision‑relevant design/architectural items

Checklist — what an applicant should prepare for design/architectural review

• Completed planning application forms per Chapter 9.32 (fees apply) — see application forms and fee resolution (submit to Community Development). § 9.32.010.D.
• Site plan showing building footprint, circulation, parking, setbacks, and grading (required for new buildings / major additions; CC‑2: new building or >10% addition triggers site plan). § 9.18.090.030.D.2.
• Building design drawings (elevations, materials, colors) — building design plan required for some rehab projects and all projects where department resolution/criteria require it. § 9.18.090.030.D.3.
• Lighting, signage and landscape plans; if landscape area meets thresholds, submit landscape documentation package and irrigation design per the Guidelines. § 9.18.120.020 – .030.
• Statement of conformance with any adopted architectural/design criteria or design guidelines applicable to the zone (Community Development Department resolutions referenced in zone chapters). § 9.18.090.030.D.1.

• CEQA checklist / documentation if the project is discretionary and may require environmental review (Chapter 9.32 references CEQA review requirements). § 9.32.010.G.

Risks & Ambiguities

Plain‑English summary

If you’re changing or building something in Garden Grove that affects the exterior — especially in the Civic Center or Garden Grove Boulevard Mixed Use areas — expect a design review tied to the zone’s site‑plan and architectural criteria. The Planning Department, Zoning Administrator, Downtown Commission (for Main Street/CC‑2) and Planning Commission each play roles depending on the zone and the scale of work; follow the site plan, building design plan and landscape submission requirements in Title 9 to avoid delays (§ 9.04.030; § 9.18.090.030; § 9.18.120).

Information gaps (from retrieved materials):

• A clear, single‑section “Design Review” definition that lists every trigger for every zone (e.g., an explicit R‑1 design‑review trigger) was not found in the retrieved excerpts — much of the code ties design review to zone chapters and to Chapter 9.32 procedures. Verify with Community Development for parcel‑specific requirements. Not found in retrieved materials.
• The actual text of the Community Development Department resolutions that function as the “architectural and design criteria” (referenced for CC‑2 and other zones) is not included in the Title 9 excerpts; those are filed with the City Clerk and should be requested.
