Grand Terrace — Design Review
Design Review under the Grand Terrace local zoning and planning code, with the controlling citations.
Last reviewed: July 2, 2026
Overview
Grand Terrace's local code handles design review under a consolidated Site and Architectural Review framework (commonly called design review). The rules live primarily in Chapter 18.63 (Site and Architectural Review) and a complementary set of objective design standards for multifamily/mixed‑use in Chapter 18.64; both explain when review is required, the three review levels, findings required for approval, application contents, and appeals. See the city's zoning rules for how design review interacts with parking, setbacks and other standards. § 18.63.010, § 18.63.020, § 18.64.010 .
Note: this page interprets and synthesizes the local ordinance language; always verify with the Community Development Director for parcel‑specific questions.
How Grand Terrace organizes design (site & architectural) review
The purpose and scope of the city's design review programme are in § 18.63.010 and § 18.63.030: the program reviews site planning (setbacks, parking, circulation, landscaping, grading, public safety, etc.) and architectural matters (style, materials, colors, massing, signage) to ensure consistency with the zoning title and General Plan. § 18.63.010, § 18.63.030 .
There are three application/review tracks: land use application, administrative site and architectural review, and site and architectural review (public hearing). The code lists which projects fall into each track and gives examples of items that can be handled by staff versus the Site and Architectural Review Board. § 18.63.020 .
Multifamily residential and mixed‑use with residential are also governed by an Objective Design Standards chapter; projects that meet those objective standards can qualify for a ministerial (non‑discretionary) path. Deviations from those objective standards trigger discretionary review under Chapter 18.63. § 18.64.010, § 18.64.020 .
Typical submittal requirements, routing, and completeness review are set out in § 18.63.040; fees and additional submittal items are determined by the Director on a case‑by‑case basis. § 18.63.040 .
(For how design review ties into parking rules, see the city's parking chapter linked below; design review explicitly considers parking and circulation as part of its scope.) § 18.63.030 .
District‑by‑district breakdown (where and how design review applies)
Below are the Grand Terrace districts where the code explicitly ties to Chapter 18.63 and the most relevant local design requirements found in the retrieved ordinance. For each district I list the purpose of the district (as stated in the code or inferred from the code headings), the kinds of uses subject to design review, and the most decision‑relevant dimensional/development notes that appear in the ordinance excerpts we retrieved. Where a precise numeric standard was not available in the retrieved text, I flag that as an information gap.
R-1 (Single‑Family Residential)
- Purpose / typical uses: single‑family dwellings and accessory residential structures. The code treats modest residential additions and accessory structures as potentially approvable at the Director level but still ties many residential actions to the land‑use/architectural review framework. § 18.63.020.B .
- Design review triggers: land use application is required for any new construction over 6 ft in height and for many renovations that change use, size, capacity, or access; certain small additions (< 500 sq ft in R‑1) can be approved administratively if materials match the existing building. § 18.63.020.B.1, § 18.63.020.B.2.d .
- Key standards to watch: front/setback and other dimensional standards are governed by the applicable zoning district development standards (see the Development Standards chapter). Verify the exact numeric front, side, and rear setbacks with Chapter 18.10/development standards. Not all numeric setback tables appear in the retrieved excerpts. Verify with the jurisdiction.
R-3 / R3‑24 Overlay (Multifamily / higher‑density option)
- Purpose / typical uses: R-3 allows multifamily housing; the R3‑24 overlay offers an optional 20–24 units per acre density for affordable housing when the owner opts in. § 18.48.010, § 18.48.020 .
- Design review triggers: multifamily developments are subject to the Objective Design Standards in Chapter 18.64; if a project complies with those objective standards and all zoning district regulations it may be eligible for ministerial review (no discretionary design hearing). If the applicant chooses deviations from the objective standards the project becomes discretionary and is reviewed under Chapter 18.63. § 18.64.010.C .
- Key standards: Objective Design Standards require LEED‑equivalent sustainability targets for multifamily (including a LEED Platinum or equivalent requirement for multifamily projects), site design rules for at‑grade parking, setbacks to mitigate privacy impacts (including a 15‑foot setback in some adjacencies) and landscape privacy screening requirements (e.g., 10‑foot landscaped setback and 20 ft trees) — these are in § 18.64.040–060. § 18.64.040, § 18.64.060, § 18.64.050 .
CM (Commercial / Mixed Commercial)
- Purpose / typical uses: commercial/manufacturing‑commercial mix (nonresidential table references). The CM district explicitly requires site and architectural review under Chapter 18.63. § 18.36.090 .
- Design review triggers: any development in CM is subject to Chapter 18.63; see § 18.63.030 for the scope (parking, circulation, landscaping, signage, loading, materials/colors). § 18.36.090, § 18.63.030 .
- Key standards: off‑street parking must conform to Chapter 18.60; signage and screening are design considerations. (Exact lot/dimensional numbers for CM must be verified in the development standards chapter — not reproduced in the retrieved excerpts.)
MR (Restricted Manufacturing)
- Purpose / typical uses: low‑intensity, low‑impact light manufacturing and industrial uses designed to avoid nuisances. § 18.39.010–.020 .
- Design review triggers: MR sites are processed with the site development standards and Chapter 18.63 procedures for significant projects. The MR site development standards table appears in the code and lists numeric lot minimums (for example, minimum lot area 20,000 sq ft, lot width 70 ft, lot depth 100 ft in § 18.39.050). § 18.39.050 .
- Key standards: uses and conditional uses are listed in the nonresidential use table referenced by § 18.39.020–.030; design review will focus on screening, setbacks, and ensuring no nuisance. § 18.39.020–.030 .
PUB (Public Facilities/Institutional)
- Purpose / typical uses: public buildings, utilities, institutional uses. The PUB district explicitly calls out that the provisions of Chapter 18.63 apply. § 18.43.080 .
- Design review triggers: any PUB district development is to follow Chapter 18.63. § 18.43.080 .
- Key standards: public projects still must meet the findings of § 18.63.060 and may require public hearing notice under § 18.63.050. § 18.63.060, § 18.63.050 .
If a particular zoning district you care about is not listed above, verify by checking the district chapter for a cross‑reference to Chapter 18.63 (many district chapters include an explicit "Site and architectural review" subsection). Examples above show how the code repeats that pattern. See district references § 18.36.090, § 18.39.050, § 18.43.080, and § 18.48.040 for explicit cross‑references. .

Practical guidance and interpretation
"Do I need design review?" — Start with the project's scope: if it is new construction > 6 ft in height, increases building size or changes use/intensity, or is a multifamily/mixed‑use project, the project will trigger at least a land use application and many will require administrative or formal site & architectural review. § 18.63.020.B.1 .
Multifamily projects: design review is handled differently if the project meets objective standards in Chapter 18.64 — meeting those standards can enable a ministerial (non‑discretionary) route and potentially avoid a public hearing; choosing deviations will cause discretionary review. § 18.64.010.C .
Staff vs. board: many accessory or modest residential alterations (sunrooms, some ground‑floor additions < 500 sq ft in R‑1, satellite dishes that are screened properly, playhouses meeting the criteria) can be approved by the Planning Director without the full board; larger projects go to the Site & Architectural Review Board or Commission. § 18.63.020.B.2, § 18.63.020.C .
Findings and conditions: approval requires the seven findings in § 18.63.060, and approvals commonly include conditions to secure those findings (landscaping, materials, screening, maintenance of common areas). Expect conditions addressing circulation, parking, and landscaping. § 18.63.060 .
Appeals and timeline: Site & Architectural Review Board decisions can be appealed to the City Council within 10 calendar days; administrative decisions can be appealed to the Planning Commission also within 10 days. Be mindful of appeal deadlines and mail/notice requirements in § 18.63.070. § 18.63.070 .
Practical cross‑references (first mention of related topics linked here): the design review process will require you to check the city's rules on parking, development standards, overlay districts, ADUs, landscaping and screening, and signage. For building code compliance you must still meet the California Building Standards Code.
Checklist (what an applicant must satisfy for a typical design review submittal)
- Determine review track: land use, administrative, or full Site & Architectural Review per § 18.63.020.
- Complete application form and pay fees as set by the Director / fee schedule (fees are assessed per project type) — see § 18.63.040.
- Provide site plan(s) showing building placement, setbacks, lot coverage, parking layout, driveways/ingress/egress, pedestrian routes and sidewalks — scope specified in § 18.63.030.
- Provide architectural elevations (materials, colors, fenestration) and sign locations per § 18.63.030.B.
- Landscaping plan (showing screening, trees, water‑efficient design where applicable) — Chapter 18.64 and Chapter 15.56 references apply for multifamily. § 18.63.030, § 18.64.040
- Any technical studies requested by the Director (traffic, drainage, stormwater management, biological/historic review, parking management plan) — Director may require per § 18.63.040 and § 18.64.020.D.
- For multifamily/mixed‑use, document compliance with objective ODS standards (or identify deviations) — § 18.64.010.C.
- If applicable, record affordable housing covenants for R3‑24 overlay projects before permits (§ 18.48.050).
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Exact numeric setbacks and lot standards for many districts | Approval and applicability of administrative vs. discretionary review hinge on dimensions | Confirm the development standards tables in the underlying district chapter (e.g., Chapter 18.10 or equivalent) — Not found in retrieved materials |
| Which specific projects are ministerial under Chapter 18.64 | A project that meets the objective standards can avoid discretionary hearings; unclear boundary if small deviations exist | Verify whether the exact design detail you plan to change still qualifies for ministerial approval or triggers Chapter 18.63 — § 18.64.010.C |
| Fee amounts and submittal checklist details | City fees and exact plan set requirements affect budget/timeline | Confirm current fee schedule and the Director's checklist; § 18.63.040 allows Director to add/delete requirements |
| Distinctions between Administrative review and Director approvals for accessory structures | Misclassification may result in unexpected public notice or appeals | Look up the full lists in § 18.63.020.B–C and verify with the Community Development Director |
| How sustainability requirements (LEED Platinum) are applied in practice | Could add design complexity and cost for multifamily projects | Confirm acceptable “equivalent standard” and submittal evidence required under § 18.64.040.A |
Plain‑English Summary
If you build or change anything that affects the look, placement, or intensity of use in Grand Terrace, Chapter 18.63 controls whether your project needs a staff review, administrative approval, or a public hearing; multifamily projects have extra objective standards where meeting those rules can speed approval. Check the specific district chapter to see how Chapter 18.63 is applied to your parcel and get the Director's checklist early. § 18.63.020, § 18.64.010 .

Frequently asked questions
Do I need design review in Grand Terrace for a small backyard accessory building?
If the accessory structure is within the limits enumerated for administrative approvals, the Planning Director can approve it without full board review; however, accessory structures that exceed trigger sizes or coverage (e.g., structures with 65% or more of the main residence living area, or 1,200 sq ft or larger) are subject to administrative or formal site & architectural review per the Director's lists. Check § 18.63.020.C for the administrative list and the definitions used by the Director.
What findings does the Site & Architectural Review Board use to approve a project?
The board must make the findings listed in § 18.63.060: consistency with the code and General Plan; visual harmony and appropriate scale; harmonious architecture, materials and colors; adequate landscaping and open space; preservation of natural beauty and avoidance of indiscriminate grading/vegetation loss; consistency of signs; and conditions necessary to secure the code’s purposes. § 18.63.060
Can a multifamily project get a ministerial approval (no hearing)?
Yes — multifamily residential and mixed‑use residential projects that fully comply with the city's Objective Design Standards in Chapter 18.64 are eligible for ministerial (objective) review; if the applicant elects to deviate from those objective standards, the project becomes discretionary under Chapter 18.63. § 18.64.010.C
Does the R3‑24 overlay change design review requirements?
The R3‑24 overlay provides an optional higher density (20–24 units/acre) for qualifying affordable housing and directs that developments under this overlay be processed as an administrative site and architectural review per § 18.48.040; it also requires an affordable housing covenant before permits. § 18.48.010, § 18.48.040, § 18.48.050
What materials do I need to submit for a site & architectural review application?
The required submittal items are set out in § 18.63.040; generally you must submit a completed application, plans (site plan, elevations), and supporting materials. The Planning Director will determine completeness and may require additional technical reports (traffic, drainage, parking management, biological, historical) as necessary. § 18.63.040
If the Planning Director approves my project, can neighbors appeal?
Yes. Decisions of the Planning Director made under administrative site & architectural review are appealable to the Planning Commission within 10 calendar days; decisions of the Site & Architectural Review Board are appealable to the City Council within 10 calendar days. See § 18.63.070 for the appeal mechanics. § 18.63.070
Will design review address parking and circulation?
Yes — the scope of site and architectural review explicitly includes vehicle and pedestrian access, internal circulation, parking lot design and parking location. Off‑street parking standards in Chapter 18.60 still apply and the Director can require a parking management plan if needed. § 18.63.030, § 18.63.040
Are sustainability requirements mandatory for multifamily projects?
Chapter 18.64 requires multifamily/mixed‑use residential projects to demonstrate compliance with the sustainability requirements listed (including a LEED Platinum or equivalent standard, and water‑efficient landscape compliance). Confirm what the Director accepts as "equivalent" in practice. § 18.64.040.A–B
Is signage considered during design review?
Yes — sign design and location are part of the architecture review and approvals must ensure signs are consistent with the scale and character of the building and the code. The Site & Architectural Review findings explicitly include sign consistency. § 18.63.030.B.4, § 18.63.060.6
Who decides minor changes after approval?
The Community Development Director may approve minor changes to an approved planned residential development (so long as density and use do not change) via administrative site & architectural review; larger changes revert to the original review authority. § 18.63.020.G (Minor changes) — see also planned development subsections.
