San Diego — Design Review

Last reviewed: July 2, 2026

Overview

San Diego does not use a separate stand‑alone chapter labelled “Design Review.” Instead, design, architectural, and site‑plan review is embedded in the City’s Land Development Code through development review and the suite of discretionary permits (Site Development Permit, Neighborhood Development Permit, Neighborhood Use Permit, Planned Development Permit, etc.). The rules explain when review is required, what findings the decision‑maker must make, and which zone and overlay rules and design manuals apply. See the Land Development Code for the procedural triggers and findings that function as San Diego’s design/architectural review standards: § 126.0101 and § 126.0102 .

Note: This page stays strictly in the scope of the local zoning / planning ordinance (Title 13 / Chapter 12 Land Development Reviews). For building code matters refer to the California Building Standards Code / Title 24 / the Building Regulations .

How "design review" works in San Diego (short synthesis)

• The City treats design/architectural/site plan review as part of its development‑permit procedures. The general purpose and applicability are set out in § 126.0101 and § 126.0102 (development review purpose; which permits require development review) .
• Specific permit procedures (decision process, required findings, and who decides) are in Chapter 12, Article 6; e.g., Site Development Permits are covered by § 126.0501 and related sections; Neighborhood Development Permit findings and enforcement rules appear in Article 6 Divisions for Neighborhood Development Permits (see § 126.0404 / § 126.0405) .
• The decision maker may require project‑specific conditions to address design, compatibility, public safety, and resource protection; findings for approval are mandatory (the project must satisfy all required findings) — see § 126.0105 and the findings cross‑references for each permit type .
• Notices and public outreach rules (who gets mailed notice and the 300‑foot rule) are in § 112.0302 and related notice rules, which affect what neighbors see during “design review” processes .

(First links to related topics in the text: San Diego uses the San Diego Zoning framework to implement design review; refer to San Diego Development Standards for dimensional rules, San Diego Parking for parking impacts that will be reviewed, San Diego Overlay Districts for supplemental design rules, San Diego ADUs for accessory dwelling considerations, and the California Building Standards Code for building code (construction) matters.)

Decision triggers, permit types and where design gets reviewed

• Development review is required when a project needs one of the discretionary development permits listed in § 126.0102: Neighborhood Use Permits, Conditional Use Permits, Neighborhood Development Permits, Site Development Permits, Planned Development Permits, Coastal Development Permits, and Variances. The code’s intention is to review schematic/conceptual design before construction permit review begins .
• Site Development Permit: purpose is to review projects whose site, location, size, or other characteristics may have significant impacts; procedures are in § 126.0501 and triggers in § 126.0502 .
• Neighborhood Development Permit: used for smaller discretionary neighborhood‑scale design/compatibility issues, with its own findings and enforcement provisions (see the neighborhood permit findings and violation rules in the Neighborhood Development Permit division) .
• Decision process levels (Process Two, Three, Five, etc.) are used to assign administrative vs. public hearing reviews; see § 126.0104 for which processes apply and § 126.0105 for the findings that must be made to approve a development permit .
• If overlays or special districts apply, the overlay’s supplemental design criteria apply (for example, the Mission Trails Design District has its own design manual and may require a Site Development Permit) — see § 132.1201 and § 132.1205 .

District‑by‑district breakdown (where design rules commonly matter)

Below are the primary base zones where design review and site plan scrutiny commonly arise. This is not an exhaustive list of every zone; it emphasizes zones where design/compatibility questions are frequent and points to the controlling local code sections.

RS / RS (Residential Single‑Unit)

• Purpose: single‑family residential development standards and neighborhood character regulation.
• Typical permitted uses: one single‑family dwelling (and accessory uses such as ADUs where allowed).
• Key dimensional/design controls: setbacks, maximum FAR tiers by lot area, garage/driveway rules, projections and yard encroachments. See maximum FAR rules in § 131.0446 (and Table 131‑04J) and setback rules referenced in § 131.0443 and related tables .
• Where it applies: all RS variants (RS‑1‑2 through RS‑1‑14) across community plan areas; minor modifications for single dwelling development may be granted by the Development Services Director in limited circumstances (see § 129.0105 for procedural coordination and § 129.0106 for fees/requirements) .
• Practical note: many single‑family additions can be exempt from development permits, but those that change setbacks, height, or are in sensitive overlays will trigger a Neighborhood Development Permit or Site Development Permit — check § 126.0102 and the applicable zone tables .

RT / RT (Residential Townhouse / Small‑lot)

• Purpose: townhome / small lot residential forms with narrower lots and stricter garage/parking siting rules.
• Typical uses: attached and detached single family units in small‑lot patterns.
• Key dimensional/design controls: required lot widths, front/street side setbacks, garage placement and alley access rules (see Table 131‑04F and the RT‑zone development regulations and garage rules) .
• Where it applies: RT‑designated subzones; design review commonly checks garage placement, driveway access, and façade articulation.

RM / RM (Multi‑Family Residential)

• Purpose: multi‑family (apartments, condominiums) with explicit standards for open space and building articulation.
• Typical uses: multi‑unit housing, sometimes mixed‑use with ground‑floor commercial depending on the community plan.
• Key dimensional/design controls: private exterior open space, common open space, FAR/height limits, building spacing and architectural projections; see § 131.0455 for private exterior open space rules and the RM tables for FAR and density limits .
• Where it applies: RM zones across community plan areas; most multi‑unit proposals will require a Neighborhood Development Permit or Site Development Permit and must meet the findings in § 126.0105/§ 126.0404 .

CR / CO / CV / CP / CR/CO/CV/CP (Commercial / Center / Village)

• Purpose: commercial and mixed‑use urban forms with district‑specific development standards for building frontage, transparency and pedestrian design.
• Typical uses: retail, office, service uses and in many cases mixed residential.
• Key dimensional/design controls: building articulation, transparency, pedestrian paths, loading/parking screening; see the commercial development regulations and Table 131‑05 series for specific lot, height and setback limits .
• Where it applies: neighborhood and downtown commercial districts; design review frequently addresses building frontage, step‑backs and parking screening.

OR / OR (Open Space / Resource)

• Purpose: protect natural resources and limit development footprint.
• Typical uses: low‑intensity recreation, conservation; development often limited by allowable development area rules in § 131.0250 .
• Where it applies: hillsides and resource areas; design review focuses on siting to minimize disturbance.

Mission Trails Design District (overlay) — Mission Trails Design District

• Purpose: supplemental design regulations intended to maintain the interface between development and Mission Trails Regional Park / San Diego River Park.
• Key rules: required compliance with Mission Trails Design Guidelines in the Land Development Manual; many proposals in the district require a Site Development Permit (Process Three) — see § 132.1201–§ 132.1205 .
• Practical note: where the overlay applies, design guidance in the District Design Manual is mandatory and will control architectural treatment, materials, and landscape interface.

Quick table — most decision‑relevant design / review items

Checklist — what an applicant must supply for a design/ site review submittal

• Complete development‑permit application per § 112.0102 (application filing rules) — Verify with the City Manager / DSD (See § 126.0103 for how to apply) .
• Concept/site plan and schematic architectural elevations that demonstrate compliance with relevant zone tables (setbacks, height, FAR) — see the applicable zone tables such as FAR rules in § 131.0446 .
• A written narrative describing how the project meets the required development‑permit findings in § 126.0105 and, where relevant, the supplemental findings for the permit type (for example, Neighborhood Development Permit supplemental findings in the Neighborhood division) .
• Evidence the project complies with overlay/area design rules (e.g., Mission Trails Design Guidelines where § 132.1205 applies) .
• Parking and circulation plan (reviewed against the City’s parking standards) — parking is a common design issue and will be checked under the Land Development Code/Chapter 14 standards and the project’s development permit review; see San Diego Parking and relevant code chapters .
• Notice list and fees; prepare for mailed notice to owners/tenants within 300 feet per § 112.0302 .
• CEQA/environmental submittals if required (the Planning Director/decision maker will require relevant initial study or EIR materials) — see Article 8 environmental document rules (Chapter 12, Article 8) and associated public review procedures .
• For historical resources or projects requiring historic incentives, documentation addressing the Secretary of the Interior standards (see the Neighborhood Development Permit supplemental findings for historic resource incentives) .

Risks & Ambiguities

Plain‑English summary

San Diego handles what people commonly call “design review” as part of its development‑permit system: the City reviews schematic site plans and architecture when a project needs a discretionary permit (Site Development Permit, Neighborhood Development Permit, etc.), and approval requires the project to meet the specific findings laid out in the Land Development Code; see § 126.0101–§ 126.0105 for the basic rules and the zone tables in Chapter 13 for dimensional standards .
