Belmont — Design Review

Design Review under the Belmont local zoning and planning code, with the controlling citations.

Last reviewed: July 1, 2026

Overview

Belmont’s zoning ordinance establishes a two-track system for review of project appearance and site layout: multi-family, commercial, mixed-use, and similar projects go through Section 13 “Design Review,” while single-family and duplex projects use Section 13A “Single Family and Duplex Residential Design Review.” These processes focus on form, materials, site planning, and objective standards set by the city’s zoning and development standards, not whether the use itself is allowed. For certain areas and districts, Belmont layers on additional, district-specific design triggers and criteria.

Key point: Belmont’s Design Review is about appearance and site design, not land use entitlements; a Use Permit addresses land-use compatibility separately (Section 13.1(b)).

How Belmont’s Design Review Is Organized

Section 13 applies to all new structures and exterior alterations unless the project is governed by Section 13A (single-family or duplex) or Section 24 (ADUs). “Exterior alteration” expressly includes changing windows/doors and repainting with different materials or colors from those previously approved.
Section 13A governs residential design review for property zoned R-1 and R-2 when building a new home or altering the square footage or floor plan; it establishes thresholds, noticing, and findings tailored to neighborhood context.
Numerous zoning districts and overlays restate that Design Review applies and, in some cases, add district-specific criteria. See the district-by-district breakdown below.

The mechanics (what to expect)

Pre-application meeting is mandatory for projects needing Zoning Administrator, Planning Commission, or City Council approval (both Section 13 and 13A).
Landscape minimum for DR projects: at least 10% of gross site area unless a district requires more; landscape plans must be prepared by a licensed landscape architect above 500 sq ft of landscaping, show species consistent with the City’s preferred lists/Green Infrastructure Plan, include irrigation, and meet MPWD WELO.
Reviewing authority and appeals vary by project scale. Minor commercial/multi-family exterior changes are handled at the Community Development Department level; other projects move to the Zoning Administrator or Planning Commission per Table 13.4; appeals flow per Section 13.4.4.
Objective design standards (Section 13.6) govern topics like consistent elevations, materials/color treatment, lighting, and screening; exceptions may be allowed by the reviewing authority in limited cases.
For “Housing Development Projects,” approval must be granted if objective standards are met and no specific, unmitigable health/safety impact exists (Housing Accountability Act framework, incorporated into Section 13).

Special overlay review: Within D‑1, no building permit for a new structure, exterior alteration or enlargement, including exterior remodeling or repainting with new colors, may be issued until plans are submitted to the Planning Commission; these are reviewed consistent with Section 13.
Additional overlay standards: Color palette review, sidewalk design, landscaping, lighting, and circulation objectives are specified for the district. See Section 22.6 and related provisions.

Planned Development (PD) Districts

Design Review linkage: Amendments to a PD’s Detailed Development Plan are treated as changes to the CUP and Design Review and processed under Section 12.4/12.12.
Submittals commonly include elevations and perspective drawings to ensure architectural unity and harmony with surroundings.

Downtown Specific Plan sub-areas within C‑2

C‑2 parcels within the Downtown Specific Plan area reference specific figures and require Design Review under Section 5.3.14 and related sections; downtown design guidelines and maps guide height, bulk, setbacks, and streetscape.

What counts as Design Review vs. Residential Design Review (13A)?

Non-residential, multi-family (3+ units), and mixed-use projects: Section 13 (site plan and architectural design review).
Single-family and duplex on R‑1 or R‑2 lots: Section 13A, with tiered thresholds, neighbor outreach, noticing, and findings focused on neighborhood compatibility.
ADUs are handled separately in Section 24; see Belmont ADUs.

Process and thresholds highlights

Minor changes at the CDD level (e.g., repainting with new approved colors, small window/door changes not adding floor area, minor lighting/landscaping plan changes, rooftop screens, and certain parking lot reconfigurations) are reviewed administratively per Table 13.4.
Zoning Administrator procedure includes noticing and the option for a meeting; the ZA may refer a case up to the Planning Commission.
Appeals: CDD-level decisions are appealable to Planning Commission (PC); ZA-level decisions may be appealed by the applicant and owners within 300 feet; PC may affirm or forward to City Council with a recommendation.

Checklist

Confirm which track applies: Section 13 (multi-family/commercial/mixed-use) or Section 13A (single-family/duplex on R‑1/R‑2).
Attend the required pre-application meeting if your project needs ZA/PC/CC action.
Prepare a complete application under Section 10.4 with plans showing all exterior work and site features.
Provide a landscape plan meeting the 10% minimum (or higher district standard), species/irrigation standards, and MPWD WELO, by a licensed landscape architect if >500 sf landscape area.
Demonstrate consistency with underlying district standards (setbacks, height, FAR), objective design standards (Section 13.6), and any overlay/district-specific criteria (e.g., D‑1 color palette, E‑2 traffic study if >5,000 sf, Downtown Specific Plan figures).
If a “Housing Development Project,” document compliance with all applicable objective standards to secure approval under Section 13.5.1.
Follow noticing/outreach per the applicable table (Table 13.4 for Section 13; Table 13A.4 for Section 13A).
Plan for potential appeal windows and conditions of approval.

Risks & Ambiguities

Issue	Why it matters	What to verify
Is my project under Section 13 or 13A?	Wrong track = delays; single-family and duplex work on R‑1/R‑2 is under 13A; most others are under 13	Confirm zoning district and project type with the City; see Sections 13.2.1 and 13A.2
“Exterior alteration” includes repainting?	Yes, if colors/materials change from prior approval	Section 13.2.1(b) clarifies repainting can trigger DR; verify scope early
Who is the reviewing authority?	Thresholds dictate timing, noticing, fees	Portions of Table 13.4 are shown; ask staff to confirm where your project lands
District overlay rules (D‑1)	Downtown has added standards and PC-level plan review	Confirm if your parcel is in D‑1; Section 22.12 governs PC review and additional design elements
Housing projects and “by-right”	Certain CMU sites process “by right” with objective DR only	Confirm parcel eligibility in the Housing Element and CMU rules (5A.1.2(k))
Landscape % conflicts	Districts like RC or E‑2 may require >10%	Check district-specific landscape minimums vs. Section 13.3.1 baseline
E‑2 large additions	>5,000 sf triggers extra criteria (traffic, shading, articulation)	Verify project size and submittal expectations under 5.7.7

Plain-English Summary

In Belmont, most commercial, multi-family, and mixed-use projects must pass a design review focused on how the building looks and fits the site, while single-family/duplex projects follow a tailored residential review. Expect to show compliant setbacks and height, submit a landscape plan (usually at least 10% of the site), and meet objective design standards. Some areas like Downtown and E‑2 add extra rules. If your project meets all objective standards—and especially if it’s a qualifying housing project—the city must approve it.

Frequently asked questions

Do I need design review in Belmont?

Most likely yes. All new structures and exterior alterations require Section 13 Design Review unless you are in the single-family/duplex track (Section 13A) or building only an ADU under Section 24. Repainting with new colors/materials also counts as an “exterior alteration.”

What is the difference between Design Review (13) and Residential Design Review (13A)?

Section 13 applies to multi-family (3+ units), commercial, and mixed-use projects and relies on objective standards; Section 13A applies to single-family/duplex in R‑1/R‑2 with tiered procedures and neighborhood-focused findings.

Are painting and window changes subject to Design Review?

Yes—if you are changing the approved design, materials, or colors. Belmont defines “exterior alteration” to include repainting with new colors/materials and window/door replacements. Minor changes may be reviewed administratively at the CDD level.

Who approves my Design Review—staff, Zoning Administrator, or Planning Commission?

It depends on project scale. Table 13.4 assigns minor exterior changes to the Community Development Department, while larger projects go to the Zoning Administrator or the Planning Commission; appeals routes are set in Section 13.4.4. Verify thresholds with staff.

What if my project is a Housing Development Project?

If your housing project meets all applicable objective standards, the city must approve it unless there’s a specific, unmitigable health/safety impact per the Housing Accountability Act (codified in Section 13.5.1).

Do Downtown projects have extra design controls?

Yes. Properties in the D‑1 Downtown Design Control District must submit plans to the Planning Commission for review before permits—this includes exterior alterations and repainting with new colors—coordinated with Section 13 procedures.

Is there a minimum amount of landscaping required?

Generally, at least 10% of the site must be landscaped for DR projects, with district-specific increases in some zones (e.g., RC, E‑2). Plans must use a licensed landscape architect above 500 sf and meet irrigation/WELO requirements.

Are public schools subject to Design Review?

No. The PS Public and Semi-Public District exempts public schools from Design Review, though other PS development is subject to Section 13.

In the E‑2 District, when do extra design criteria kick in?

For new buildings or additions over 5,000 sq ft, you must address added criteria such as traffic analysis, enhanced landscaping, facade articulation, and screening.

Can the city allow alternatives to active-ground-floor window transparency in CMU?

Yes. Alternatives may be approved through Design Review where a use’s operations make compliance impractical (e.g., theaters), provided the street-facing wall is enhanced with relief, detail, and landscaping to maintain pedestrian interest.
