Exeter — Design Review

Last reviewed: July 2, 2026

Overview

This page summarizes what Exeter’s zoning ordinance requires for design review (downtown/historic design review) and site plan review: who reviews projects, when review is required, key application materials, and the decision standards that matter for zoning, facades, landscaping, and site layout. The city separates a downtown-focused DD‑X (Downtown Design Overlay) design-review process from the general site plan review used across most commercial, industrial and some overlay districts; both are part of the Title 17 Zoning rules. See Exeter’s zoning and land-use menus for related topics: Exeter Zoning and Exeter Land Use.

Note: this page sticks to design review / site-plan-review material in the municipal code. For building code permitting (Title 24) see the California Building Standards Code.

How Exeter organizes review authority

• The Design Review Committee handles architectural elevations and projects in the Downtown and Historic combining districts (§ 17.03.08) .
• The Site Plan Review Committee (staff technical members) reviews site plans and forwards a recommendation to the Planning Commission; the Planning Commission makes the final decision unless appealed (§ 17.03.07; § 17.54.05–07) .
• For downtown projects the Downtown Design Review Committee makes a decision and that decision can be appealed to the City Council (§ 17.46.06–07) .

For related topics consulted while preparing designs, Exeter routes applicants to chapters covering development standards, parking, overlay districts, historic preservation, and ADUs.

District-by-district breakdown

Below are the Exeter districts that specifically call out design or site-plan review requirements in Title 17. For each district I list the purpose, typical permitted uses, key dimensional/development standards, and where review applies with code references.

DD‑X (Downtown Design Overlay)

• Purpose: to ensure a pedestrian-oriented, visually pleasing downtown and to implement the Downtown Specific Plan; design guidelines and review procedures are codified in the overlay (§ 17.46.01) .
• Typical permitted uses: uses of the base district to which the overlay is applied (the overlay follows the base district permitted/conditional lists) (§ 17.46.03–04) .
• Key standards: projects must comply with downtown design guidelines; many façade/material/scale provisions are in the design guidelines (e.g., scale, proportion, materials, color, historic restoration guidance) (§ 17.46.13) .
• Where it applies: the overlay is combined with downtown base zones (e.g., DD‑CC) and if the overlay is more restrictive it governs (§ 17.46.02) .
• Review trigger / process: Downtown Design Review Committee reviews applications and may approve, approve with conditions, or deny based on consistency with the downtown guidelines; appeal to City Council available (§ 17.46.06–07) .
• Application materials: nine copies, site plan, elevations scaled at 1/4" = 1', material/color samples, landscaping and lighting, sign locations, and other details (§ 17.46.05) .
• Special notes: some minor exterior work is exempt (e.g., limited repairs, painting consistent with guidelines, single‑family dwelling alterations within downtown) (§ 17.46.12) .

MU (Mixed Use)

• Purpose: allow compatible combinations of residential, office and commercial uses that implement the Downtown and Southwest Specific Plans (§ 17.21.01) .
• Typical permitted uses: combinations of uses listed in R‑1, RM‑1.5, RM‑3, CN, PO or CC (larger list is available in those chapters) (§ 17.21.03) .
• Key standards: minimum site area 5,000 sq ft, maximum commercial building height 35 ft, side/rear yards generally no requirement unless adjacent to residential (10 ft) (§ 17.21.05) .
• Where review applies: site plan must be submitted and approved consistent with site plan review rules (§ 17.21.04; § 17.54.02) .

CN (Neighborhood Commercial)

• Purpose: small‑scale commercial serving nearby neighborhoods; design must be compatible with surrounding residential neighborhoods (§ 17.22.01) .
• Typical permitted uses: retail & service (e.g., bakery, bank, barber/beauty, small grocery, restaurants) — full list appears under § 17.22.02 .
• Key standards: design standards require breaking up large façades, offset rooflines, landscaping and trash enclosure screening; see § 17.22.10 and related landscaping chapters for detail (§ 17.22.10; related Landscaping & Screening chapter) .
• Where review applies: site plan review and specific design standards in the CN chapter require committee/commission review (§ 17.22.04; § 17.22.10; § 17.54.02) .

CC (Central Commercial)

• Purpose: central business district uses and enhancement (retail, offices, civic uses) (§ 17.24.01) .
• Typical permitted uses: professional offices, retail stores, parking lots, banks, specialty stores; full list at § 17.24.02 .
• Key standards: design standards and streetscape/landscaping requirements are included in the CC chapter (see § 17.24.10 and 17.24.09) .
• Where review applies: site plan review required prior to construction (§ 17.24.05; § 17.54.02) .

CH (Highway Commercial)

• Purpose: accommodate highway‑oriented commercial activities but with high design standards (landscaping, signage, parking) (§ 17.30.02) .
• Typical permitted uses: bus depots, convenience stores, hotels, restaurants, service stations, parking lots (§ 17.30.02) .
• Key standards: minimum site area 10,000 sq ft, max building height 45 ft (35 ft for accessory), front yard 20 ft (side/rear special rules when abutting residential) (§ 17.30.06) .
• Where review applies: no development may be constructed until it has passed site plan review per Chapter 17.54 (§ 17.30.05) .

O (Open Space)

• Purpose: parks, floodplains, reservoirs, agriculture; low‑intensity public/open uses (§ 17.38.01) .
• Typical permitted uses: parks, cemeteries, drainage basins, environmentally sensitive lands, golf courses, agriculture (§ 17.38.02) .
• Key standards: minimum site area 10,000 sq ft, max height 35 ft (accessories 15 ft), front yard 25 ft; site plan review required (§ 17.38.06; § 17.38.05) .

PD‑X (Planned Development Overlay)

• Purpose: to allow comprehensive, “smart growth” development designs that may deviate from base zone standards but require a development plan and site plan review (§ 17.42.01–02; § 17.42.05–06) .
• Typical permitted uses: those of the underlying base zone; the PD overlays are suffix‑notated (e.g., PD‑R‑1) (§ 17.42.03) .
• Key standards & process: prior to reclassification the applicant must submit a development plan and a site plan consistent with Chapter 17.54; no construction until site plan is approved (§ 17.42.05–06; § 17.54.02) .

At‑a‑glance table — decision‑relevant standards / triggers

Practical guidance (plain‑language synthesis)

• If your project is downtown or in a designated historic overlay, expect a distinct Downtown Design Review process with design‑guideline checks (façade rhythm, materials, awnings, signage). Start with the guidelines in § 17.46.13 and plan to submit full elevations and material samples (§ 17.46.05–06) .
• For most commercial or multi‑unit proposals, prepare for site plan review: a staff committee recommendation is forwarded to the Planning Commission; the review checks land‑use consistency, impacts, circulation, parking and landscaping (§ 17.54.05–07) . See parking and development standards for chapter‑level requirements you will need to meet.
• If the project is an overlay (e.g., PD‑X or DD‑X), the overlay’s rules prevail where they are stricter (§ 17.46.02) . Consult the overlay districts menu early.
• For smaller projects (e.g., single‑family homes, accessory structures) the site plan process may be exempt — but verify with the Planning Director because some exceptions are discretionary (§ 17.54.03; § 17.54.04) . If you are pursuing an ADU, also consult Exeter’s ADU rules and California ADU law because state law can change local processing requirements.
• City staff (Planning Director) and the Site Plan Review Committee are your procedural contacts; the Planning Director participates on committees and prepares administrative resolutions after committee actions (§ 17.03.05–08) .

Checklist

• Confirm whether the property is within the DD‑X overlay or H‑X historic overlay. (§ 17.46.*; Ch. 44)
• Prepare site plan showing lot lines, building footprints, yards, parking, access, lighting, trash enclosures, grading and drainage, landscaping and irrigation. (§ 17.54.04; Exhibit list)
• Prepare elevation drawings (scaled to at least 1/4" = 1') with materials and treatments noted; provide material/color samples. (§ 17.46.05; § 17.46.08)
• If in Downtown overlay: submit nine copies and expect Downtown Design Review Committee review; pay applicable fees. (§ 17.46.05; § 17.46.06)
• Identify exemptions (single‑family dwellings, small accessory increases < 25% may be exempt). If unsure, get a pre‑application meeting with Planning Director. (§ 17.54.03–04)
• If project requires a conditional use permit or PD overlay, assemble master plan documents and concurrent site plan materials. (§ 17.21.02–04; § 17.42.05–06)
• Verify whether an architect's stamp is required for the downtown application drawings. (§ 17.46.08)

Risks & Ambiguities

Information Gaps

• Chapter‑level numeric development standards for R‑1, RM‑1.5, and RM‑3 (typical single‑family/multifamily setbacks, lot sizes) were not present in the retrieved excerpts above. Not found in retrieved materials — verify with the full Title 17 chapters for residential zones.
• Any recent amendments after the copy of the ordinance used here (e.g., updates to application copy counts, electronic submission allowances, or state law implementation) are not captured. Verify with Planning Department for current submittal rules.
• Fee schedules and the current Planning & Building counter procedures (digital submittal, number of sets, electronic file formats) are not in the provided text. Verify with City staff.

Plain-English Summary

If you are building or changing a non‑minor commercial or multi‑unit project in Exeter, you will generally need a site plan review and, if your project is downtown or in the historic overlay, a downtown design review that checks facades, materials, signage and landscaping; both processes require specific drawings, materials samples, and committee/staff sign‑off before building permits are released (§ 17.54.; § 17.46.).
