Overview

Design review in Sunnyvale is the local, site-and-architectural review process applied under the Zoning Code (Title 19) to new construction and exterior changes intended to protect neighborhood character and ensure projects meet adopted design guidelines. The program is governed by Chapter 19.80 (purpose, guidelines, applicability, procedures and findings) and is implemented by the Director of Community Development, the Planning Commission, and (on appeal) the City Council. See the city’s rules for how design guidelines are adopted and where discretionary review is required (§ 19.80.010–050) .

Note: this page focuses strictly on what the Sunnyvale Zoning Code (Title 19) says about design review and closely related local review paths; building code (Title 24), statewide housing mandates, or tenant law are out of scope. For the City’s broader planning menu, see the Sunnyvale overview and the specific Sunnyvale Zoning pages linked below.

What the ordinance requires (short list)

  • The City Council adopts citywide design criteria and the Director maintains guidelines used in review (§ 19.80.020) .
  • Any proposed use requiring a discretionary land use permit that includes new construction or exterior changes is subject to design review (§ 19.80.030) .
  • Permitted uses that involve new construction or exterior changes are also subject to design review; minor cases may be handled through building plan check or a miscellaneous plan permit (§ 19.80.030, Chapter 19.82) .
  • Director-level approvals may be made without notice, with notice (no hearing), or the Planning Commission may hold a public hearing depending on project type, scale, and thresholds such as FAR/gross floor area (§ 19.80.040) .
  • The decision standard is that the project “will conform with the applicable criteria and various guidelines for design review established by the city council” (§ 19.80.050) .

How decisions are made and where design review sits in the permit flow

  • The City Council adopts general design criteria; the Director maintains the detailed design guidelines used by staff in review (§ 19.80.020) .
  • For projects tied to a discretionary entitlement (use permit, special development permit, etc.), design review is done as part of that entitlement review; for ministerial or permitted projects with exterior changes, design review may occur through building plan check or a Miscellaneous Plan Permit (Chapter 19.82) (§ 19.80.030, § 19.82.020) .
  • The Director may approve certain low‑impact projects without public notice; higher-impact residential projects (two‑story or projects exceeding FAR/gross floor area thresholds) require notice or a Planning Commission hearing (§ 19.80.040) .

District-by-district breakdown (where design review interacts with districts)

Below are the zoning districts that the Title 19 excerpts tie directly to design-review procedures and the key local standards you need to check. Each district name and numerical standard below is bolded and tied to the controlling Sunnyvale Zoning Code section(s).

R-0 (Residential)

  • Purpose / typical uses: single-family detached and low-density residential. Uses and review types are listed in the residential use tables and Chapter 19.18 (§ 19.18.030) .
  • Design-review trigger: New single‑family or duplex residences and exterior changes are subject to design review; single‑story minor additions under the threshold may be exempt from full procedures but the Director can require review for significant exterior changes (§ 19.80.030) .
  • Key dimensional standards to cross‑check when preparing materials: front yard minimum 15 ft, average front yard 20 ft, side yard totals and rear yard standards as listed in Table 19.34.030 (§ 19.34.030) .
  • Where it matters: small single‑family projects often go to the Director; larger projects that exceed FAR/gross floor area thresholds are elevated to Planning Commission (§ 19.80.040) .

R-1 (Residential)

  • Purpose / typical uses: single-family residential uses; Table 19.18.030 controls permitted, MPP, or UP status (§ 19.18.030) .
  • Dimensional highlights (Table 19.34.030): Front yard min 15 ft, Front yard average 20 ft, Total side yards = 20% of lot width but not less than 15 ft, one side 6 ft, rear yard 20 ft (§ 19.34.030) .
  • Design-review pathway: single‑story additions below the FAR/GFA threshold may be approved administratively; two‑story or projects exceeding thresholds require notice or a hearing (§ 19.80.040) .

R-2 (Residential, duplex/low-multi)

  • Purpose / typical uses: duplexes, small multi-family; use table in Chapter 19.18 applies (§ 19.18.030) .
  • Dimensional highlights (Table 19.34.030): Front yard min 15 ft, Average front yard 20 ft, side yard totals and minimum one-side 4 ft, rear yard 20 ft (see § 19.34.030) .
  • Design-review pathway: small single‑story work may be director‑level; second‑story work or projects above FAR/GFA threshold require notice/hearing (§ 19.80.040) .

R-3, R-4, R-5 (Medium/High density residential)

  • Purpose / typical uses: multi‑family residential (apartments, townhomes) with increasing density allowances in R-3, R-4, R-5; permitted uses and review types are in Table 19.18.030 (§ 19.18.030) .
  • Dimensional & open‑space rules: multifamily open space and landscaping rules apply (Chapter 19.37) and minimum usable open space provisions apply specifically to R-3, R-4, R-5 (§ 19.37.100) .
  • Design-review trigger: multiple‑family projects of 3–50 units in R-2, R-3, R-4, R-5, R‑MH require design review (and may need Planning Commission hearing depending on other permits) (§ 19.80.040) .

R‑MH (Mobile-home residential)

  • Purpose: manufactured/mobile home park compatibility and standards; design review applies for multi‑unit developments as above (§ 19.80.040) .
  • Check: lot standards and permitted uses are in the residential tables and Chapters 19.30–19.37.

Commercial / Office / Industrial districts (C‑1, C‑2, C‑3, O, M‑S, M‑3, LSAP/MXD series)

  • Purpose / typical uses: local retail (C‑1 etc.), professional office (O), and industrial/service parks (M‑S, M‑3), plus LSAP/MXD specific zones for large‑scale mixed‑use nodes; see the use tables and LSAP-specific Tables (e.g., 19.35.060) for detailed allowances (§ 19.18.030, § 19.35.060) .
  • Dimensional highlights: FAR and height limits are tabulated in Table 19.32.020 and in LSAP Tables 19.35.060/070; example entries (M‑S and M‑3) and the form of the table are in § 19.32.020 and § 19.35.060 — always check the applicable table row for your zoning designation (§ 19.32.020, § 19.35.060) .
  • Design-review implications: new nonresidential buildings adjacent to residential zones or exterior modifications adjacent to residential zones trigger design review (and sometimes the Planning Commission) (§ 19.80.040) .

Notes on the district breakdown above: the Zoning Code uses multiple tables (Tables 19.34.030, 19.32.020, 19.35.060, etc.) to show exact setbacks, heights, lot coverages, and FAR by district; for a parcel‑specific answer you must verify the parcel’s zoning and read the applicable table row and footnotes (§ 19.34.030, § 19.32.020) .

Quick reference table — key decision‑relevant standards and code refs

Topic What matters to a reviewer Code reference
Who adopts design rules City Council establishes design criteria; Director maintains guidelines § 19.80.020
Applicability (discretionary & permitted work) Any discretionary permit with new construction/exterior work; permitted work with exterior changes is also reviewed (§ 19.82 MPP covers some minor cases) § 19.80.030, § 19.82.020
Director vs Commission review Director: some projects (no notice / notice‑only); Planning Commission: two‑story or projects exceeding FAR/GFA thresholds, 3–50 unit multifamily § 19.80.040

FAR / lot coverage lookups Consult Table 19.32.020 for district FAR/height/coverage values; thresholds referenced in review triggers § 19.32.020

Practical guidance / how to prepare an application

  • Start with the City's adopted design guidelines (maintained in the Dept. of Community Development) and align exterior materials, massing and landscaping to those criteria (§ 19.80.020) .
  • Determine whether your project is discretionary or permitted and whether it contains exterior changes that trigger design review (§ 19.80.030) .
  • For single‑family/duplex work, check the FAR/gross floor area thresholds in § 19.32.020 to see whether the Director can act, notice is required, or the matter goes to Planning Commission (§ 19.80.040) .
  • If your project is adjacent to residential zoning, anticipate stricter scrutiny (new nonresidential buildings or exterior modifications next to residential properties are listed triggers) (§ 19.80.040) .
  • Provide streetscape elevations that show adjacent properties for on‑site posting requirements in single‑family/duplex notices (§ 19.80.040) .
  • If you propose minor changes, explore a Miscellaneous Plan Permit (MPP) route for administrative review of colors, materials, fencing, small accessory structures, landscape plans, and parking configurations (§ 19.82.010–020) .

Checklist (what an application must satisfy)

  • Demonstrate conformance with the Council‑adopted design guidelines (§ 19.80.020) .
  • Identify whether the project is discretionary or permitted and list associated entitlements (use permit, SDP, MPP) (§ 19.80.030, § 19.82.020) .
  • Provide site plans, elevations, materials/colors, and streetscape elevation (adjacent homes) for single‑family/duplex notices (§ 19.80.040) .
  • Show compliance with applicable setbacks, FAR, lot coverage, landscaping and parking standards (consult Tables 19.32.020, 19.34.030, Chapter 19.37, Chapter 19.46) (§ 19.32.020, § 19.34.030, § 19.37.040) .
  • Prepare for public notice timelines or hearings if thresholds are exceeded (§ 19.80.040, Chapter 19.98) .
  • If proposing an ADU, confirm ministerial ADU review rules and timelines under Chapters 19.79 and 19.82 (§ 19.79.100, § 19.82.020) .
  • Be ready to show how the project meets the design-review finding (conforms to applicable guidelines) (§ 19.80.050) .

Risks & Ambiguities

Issue Why it matters What to verify
FAR / GFA thresholds referenced in design‑review triggers The Director vs. Commission path depends on whether a project “does not exceed either the FAR or gross floor area threshold established in Section 19.32.020” (§ 19.80.040) Verify the exact numeric FAR or gross floor area threshold that applies to your lot’s zoning row in § 19.32.020 (Table may have district‑specific rows and footnotes). See § 19.32.020 .
Parcel‑specific district rules and footnotes Tables include footnotes that alter setbacks, minimum lot widths, or special adjacency rules (LSAP or specific plans) (§ 19.35.070, § 19.34.030) Verify parcel zoning, any specific- or precise‑plan overlays, and the applicable table footnotes before assuming numeric standards.
“Significant modification” exemption language for single‑family The Director can still require review for changes even when an addition is under the 20% threshold — “significant” is partly discretionary (§ 19.80.030) Expect discretionary judgment — discuss scope with staff early; ask for written interpretation if unclear.
Applicability to ADUs ADUs are generally ministerial under Chapter 19.79, but exceptions exist and the city may delay an ADU decision if submitted with a new main dwelling (§ 19.79.100, § 19.82.020) Confirm the ADU submittal path with staff for your parcel; verify whether design review or MPP is required.

Plain‑English summary

Sunnyvale’s design‑review rules require that new buildings and exterior changes follow city design guidelines and be checked by the Director or the Planning Commission depending on size, type and adjacency to residences; small, routine changes may be handled through building plan check or a Miscellaneous Plan Permit, but check FAR/gross floor area thresholds and local tables because those numbers determine whether notice or a hearing is required (§ 19.80.020–050, § 19.82.020) .

Frequently asked questions

Do I need design review in Sunnyvale?

If your project includes new construction or exterior changes and is tied to a discretionary land use permit, you must go through design review; permitted uses that add or change the exterior are also subject to design review (some minor cases can be handled through building plan check or a Miscellaneous Plan Permit) (§ 19.80.030, § 19.82.020) .

What triggers a Planning Commission hearing versus Director approval?

The Code lists three review tracks: Director approval without notice for limited cases, Director with public notice/no hearing for some projects, and Planning Commission hearings for larger or higher‑impact projects — e.g., new single‑family/duplex residences that exceed the FAR or gross floor area thresholds in § 19.32.020, and multifamily projects of 3–50 units in certain districts (§ 19.80.040) .

What is the deciding legal standard for approving design review?

The Director or Planning Commission may approve a design review only upon finding that the project’s design and architecture will conform with the applicable design criteria and guidelines adopted by the City Council (§ 19.80.050) .

Are small single‑story home additions exempt from design review?

Single‑story additions that add or modify less than 20% of the existing floor area are generally exempt from the full procedural requirements, but the Director may require design review if the change is “significant” to exterior appearance (materials, window placement, roof form, etc.) (§ 19.80.030) .

Where do I find the setback and FAR numbers I must meet for my lot?

Setbacks are listed in Table 19.34.030 and related front‑yard rules (§ 19.34.030–045); FAR, height, and lot coverage values are listed in Table 19.32.020 and LSAP tables like 19.35.060 for special plan districts — always check the table row for your zoning district and applicable footnotes (§ 19.34.030, § 19.32.020, § 19.35.060) .

Will adding an ADU trigger design review?

ADUs are generally reviewed ministerially under Chapter 19.79 and certain ADU categories are exempt from separate utility fees; however, if an ADU application is submitted together with a new primary dwelling the City may delay ADU action, and some ADU projects may still require MPP or discretionary review if they don’t meet objective standards (§ 19.79.100, § 19.82.020) .

If my project is next to homes, will that increase the chance of a hearing?

Yes. New nonresidential buildings or exterior modifications that are adjacent to a residential zoning district are explicitly listed as triggers for Design Review with public notice or for Planning Commission hearing depending on thresholds (§ 19.80.040) .

How do I appeal a Director’s design‑review decision?

Decisions by the Director under the design‑review subsections may be appealed by the applicant, the owner of the subject property, or the owner of property within the required noticing radius, to the Planning Commission; Planning Commission decisions are further appealable to the City Council in limited circumstances (§ 19.80.040(c)–(e)) .
