Overview

Design review in Winters is the planning-review process the city uses to ensure new and altered buildings and site improvements fit the city's visual character and form-based downtown rules. The local rules are codified in Chapter 17.36 (Design Review) and operate alongside the downtown form‑based code (Chapter 17.58), the lot and setback standards in Chapter 17.56, landscaping rules in Chapter 17.76, and historic‑district review in Chapter 17.108. See the city's zoning menu for related topics like design review, parking, and development standards while you prepare materials.

Key controlling citations: § 17.36.010, § 17.36.020, § 17.36.030, § 17.36.040, § 17.58.015 .

What the Winters code requires (short list)

  • Design review is required for specific project types and locations — see § 17.36.020. Major triggers: new non‑residential buildings ≥ 500 sq ft, additions ≥ 500 sq ft, any new multifamily construction, and new single‑family units (projects with multiple units reviewed as a group) .
  • Design review is implemented through the site's site‑plan review and is generally heard by the Planning Commission; procedural notice and hearing rules follow Chapter 17.16 and the site plan review rules in § 17.36.030 .
  • The Commission must make findings based on the criteria listed in § 17.36.040 (massing, materials, avoiding blank facades, screening mechanicals, landscaping conformance with Chapter 17.76, and conformity with Winters design guidelines / downtown form‑based standards) before approving a design review site plan .

District‑by‑district breakdown (how design review interacts with local zones)

Below are the Winters zoning districts most relevant to design review. For each I list the purpose/where it’s used, typical permitted uses (high‑level), the most decision‑relevant dimensional standards, and where design review shows up.

Note: the code contains full tables Table 3A / Table 3B (lot, FAR, height, and minimum lot area) and a Setback Matrix (Table 4); consult those tables for parcel‑specific numbers. See the development standards pages when you need dimensional specifics: development standards. All cited standards below come from the Winters zoning title (various tables and chapters) .

D-A (Downtown‑A form‑based district)

  • Purpose / where it applies: Core downtown historic/commercial blocks; regulates form and frontage to preserve a pedestrian, historic storefront character under the form‑based code Chapter 17.58 .
  • Typical permitted uses: Retail, restaurants, offices, residential above ground floor (subject to Table 17.58 allowed uses and conditional uses) .
  • Key dimensional standards: Maximum height 45 ft (varies by frontage type; Table 17.58‑3) and an area‑wide residential cap of 20 dwelling units/acre for downtown; mandatory architectural standards and frontage/build‑to rules apply during design review § 17.58.060 and § 17.58.070 .
  • Design review: All qualifying projects listed in § 17.36.020 within D‑A must have design review prior to building permits; the form‑based code standards are mandatory and enforced in design review § 17.58.015 .

D-B (Downtown‑B form‑based district)

  • Purpose / where it applies: Transition blocks in downtown with slightly different frontage and setback expectations; still within the downtown master plan area Chapter 17.58 .
  • Typical permitted uses: Similar to D‑A but with different frontage allowances per the regulating plan (see Table 17.58‑4) .
  • Key dimensional standards: Maximum height 45 ft on most frontages (some secondary streets 35 ft) per Table 17.58‑3; frontage types and build‑to lines govern street relationship .
  • Design review: Same requirement as D‑A — design review enforces the downtown form‑based mandatory standards § 17.58.015 .

R‑1 (Single‑family residential)

  • Purpose / where it applies: Low‑density single‑family neighborhoods (standard residential zone) .
  • Typical permitted uses: Single‑family homes and customary accessory structures; some home occupations subject to rules .
  • Key dimensional standards: Maximum site coverage 50% (single‑story), height 30 ft, minimum lot area ~7,000 sf average (6,000 sf absolute minimum) (Table 3A / 3B) and front/side/rear setbacks per Table 4; accessory building rules and setback exceptions in § 17.56.020 apply .
  • Design review: New single‑family construction is listed as subject to design review (all new single‑family units are subject to design review; multiple units in a subdivision can be reviewed as a group) § 17.36.020(C) .

R‑2, R‑3, R‑4 (Higher‑density residential zones)

  • Purpose / where they apply: Duplex/multi‑family and higher density residential areas; R‑3/R‑4 allow small multifamily projects and higher coverage/height as shown in Table 3A/3B .
  • Typical uses: Duplexes, townhomes, small apartment buildings (subject to unit density limits and minimum lot sizes) .
  • Key dimensional standards: Progressive increases in allowed site coverage (R‑3 60% / R‑4 70%) and heights (R‑3 35 ft, R‑4 45 ft); minimum lot areas differ by zone (Table 3B) .
  • Design review: New multifamily construction triggers design review (see § 17.36.020(B)) and the planning commission focuses on massing, variety (avoid repetitive tract designs), and pedestrian orientation per § 17.36.040(G) .

C‑1, C‑2, C‑H (Commercial zones)

  • Purpose / where it applies: General neighborhood and highway commercial; C‑H is highway‑oriented commercial; C‑2 allows higher FAR and height where noted (see Table 3A) .
  • Typical uses: Retail, restaurants, offices, service uses; accessory office/retail in industrial buildings allowed up to specified percentages .
  • Key dimensional standards: FAR and height vary (example: C‑1 FAR 0.40, C‑2 FAR up to 2.0 for some uses, heights up to 45 ft where shown) — see Table 3A for the zone your parcel is in .
  • Design review: Non‑residential buildings ≥ 500 sq ft and additions ≥ 500 sq ft are subject to design review § 17.36.020(A); the Commission will evaluate materials, blank walls, mechanical screening, and landscaping § 17.36.040 .

M‑1, M‑2, BIP (Industrial / business park)

  • Purpose / where it applies: Light to heavier industrial and business park areas; design standards aim to allow industrial activity while minimizing visual impacts .
  • Typical uses: Manufacturing, distribution, business park offices; limited retail accessory uses (20% rule) .
  • Key dimensional standards: FARs and heights vary by subzone (see Table 3A) — M‑1 height ~40 ft, M‑2 ~50 ft, coverage and setbacks per Table 3A/3B .
  • Design review: Metal buildings > 120 sq ft anywhere in the city require design review § 17.36.020(F); larger industrial buildings and parking/landscaping proposals are reviewed via site plan/design review § 17.36.030 .

P‑D (Planned Development overlay)

  • Purpose / where it applies: Applied as a suffix overlay (“-PD”) to a base zone to authorize project‑specific standards and design; the P‑D allows tailored development standards and is established by a PD permit and rezone/plan process § 17.48 .
  • Typical uses: Mixed residential, commercial or combinations where a site‑specific plan creates public benefit; uses permitted are those in the approved PD plan § 17.48.030 .
  • Key dimensional standards: Per the approved PD plan (Table 2B and PD plan set the minimum lot area, densities and any deviations) — design review enforces the PD’s design provisions in the permit conditions § 17.48.040 .
  • Design review: PD plans include the design standards and architectural elevations; the planning commission reviews conformance and may approve PD modifications or minor changes are handled by the zoning administrator per PD rules § 17.48 .

Historic districts / Main Street Historical District

  • Purpose / where it applies: Preserve exterior character of contributing structures; Chapter 17.108 establishes review rules and limits the Commission to exterior features only and prescribes special criteria (e.g., Secretary of the Interior standards) .
  • Typical permitted uses: Repairs compatible with historic character; substantial exterior work or demolition on a cultural resource requires prior approval § 17.108.050–070 .
  • Design review overlap: Work within the historic district has an additional layer of review by the Historic Preservation Commission; no building permit for exterior work is issued without the Commission’s certificate § 17.108.050(E–F) .

How the design review process works (practical synthesis)

  • Filing and scope: Conceptual (pre‑application) design review is optional and advisory; formal design review is part of the site plan review process and is a discretionary Planning Commission action for the projects listed in § 17.36.020 — expect a noticed public hearing when the commission is the reviewing body § 17.36.030 and § 17.36.070 .
  • What reviewers focus on: The Commission’s evaluation is explicitly design‑oriented: building mass and scale, rooflines/height, material quality and colors (new construction), avoiding blank walls, mechanical screening, and landscape/parking treatment (referencing Chapter 17.76) § 17.36.040 .
  • Conditions and findings: Approval requires findings that the site plan meets the listed design criteria; the Commission can add conditions (e.g., material changes, additional screening, landscape modifications) § 17.36.050 .
  • Expiration / revocation: Site plan approvals via design review follow the same revocation/expiration/modification rules as other approvals in § 17.24.070(A) (e.g., time limits, potential revocation for noncompliance) and design approvals can be modified under the same rules § 17.36.060 .

Practical tips: use the optional conceptual review to test massing and material palettes (advice is advisory only), coordinate parking and landscape design early (parking standards are reviewed during site plan/design review), and expect downtown projects to be evaluated under the form‑based Chapter 17.58 mandatory standards as part of design review .

Checklist

  • Confirm whether your project triggers design review under § 17.36.020 (nonresidential ≥ 500 sq ft, any new multifamily, any new single‑family, metal buildings >120 sq ft)
  • If in D‑A or D‑B, prepare elevations, frontage/build‑to compliance, and form‑based compliance evidence per § 17.58.015–070
  • Prepare site plan with parking, circulation, and landscape plans consistent with Chapter 17.76 and the parking standards; show tree canopy strategy for parking lots § 17.76.040
  • Provide material samples, color palettes (new construction only), and mechanical screening details per § 17.36.040(B–D)
  • If in a historic district or working on a designated cultural resource, supply the Historic Preservation Commission application materials and allow for its review § 17.108.050
  • Check setbacks, lot coverage, FAR and height against Table 3A/3B and Table 4 and include a compliance table in your packet § 17.56.010
  • Consider submitting a conceptual design review before formal submittal to get advisory feedback § 17.36.070

Risks & Ambiguities

Issue Why it matters What to verify
Whether a small single‑family project will be routed to design review The code states “any single‑family residential units is subject to design review,” but practice may vary for minor permits Verify at intake whether the community development director treats minor rebuilds as qualifying modifications (see § 17.58.060 and qualifying modification language) and confirm whether the project can be handled at plan check
Downtown form‑based mandatory vs. code silence The downtown form‑based chapter prevails where it addresses a topic; elsewhere the general code applies Confirm which regulating plan street typology applies to your frontage (Figure 17.58‑1) and which specific frontage/build‑to standard applies § 17.58.015–020
Historic district overlap Historic Preservation Commission rules can add separate submittal requirements and timelines If within Main Street Historical District, submit to Historic Preservation Commission as required and expect exterior review, certificates, and possible 180‑day demolition holds § 17.108.050–070
Lot‑specific setbacks and PD overrides Site‑specific PD plans and recorded subdivision conditions can supersede general standards Verify recorded PD plan or subdivision conditions and consult Table 3A/3B and PD ordinance language § 17.48 and § 17.56.010
Landscaping and parking metrics Design approval requires a landscape plan; parking layout affects whether the Planning Commission treats the site plan as major Confirm tree spacing, canopy expectations (50% within 10–15 years) and any downtown parking siting rules early § 17.76.040

Plain‑English Summary

If you are building or making notable exterior changes in Winters you will likely need design review: the Planning Commission (or its designee) will look at massing, materials, landscaping, parking and how the building meets downtown form‑based rules; downtown (D‑A/D‑B), multifamily, and most new single‑family projects are explicitly reviewed and the code gives mandatory criteria the Commission must apply § 17.36.020–040, § 17.58.015 .

Frequently asked questions

Do I need design review for a 300 sq ft commercial addition in Winters?

No — a nonresidential addition smaller than 500 sq ft is not listed as a mandatory Planning Commission design‑review trigger; design review is required for nonresidential construction or additions ≥ 500 sq ft per § 17.36.020(A). However, the community development director may still require review if the exterior changes are visually significant — verify at intake with staff § 17.36.020(E) .

What projects always go to Planning Commission for design review?

The code lists: new nonresidential buildings or additions ≥ 500 sq ft, new multifamily construction, and all new single‑family residential units (projects with multiple units can be reviewed as a group) — see § 17.36.020 .

How does downtown form‑based code change design review in the D‑A/D‑B zones?

Projects in D‑A and D‑B are subject to form‑based, mandatory architectural and frontage standards; all qualifying projects under § 17.36.020 within D‑A/D‑B must pass design review demonstrating conformance with Chapter 17.58 (including Table 17.58‑3 height and frontage/build‑to requirements) § 17.58.015–060 .

Does the Historic Preservation Commission review overlap with design review?

Yes. Work on designated cultural resources or within a historic district requires Historic Preservation Commission approval for exterior work; the Commission considers only exterior features and issues certificates of approval/rejection before building permits are issued § 17.108.050–070 .

Are metal storage buildings treated differently for design review?

Yes. The code explicitly requires design review for metal buildings exceeding 120 sq ft in any district — see § 17.36.020(F) .

What landscaping will the Planning Commission expect during design review?

Landscape plans must meet Chapter 17.76 standards: permanent maintenance, plant sizing, irrigation plans, and parking lot tree canopy goals (minimum 50% tree canopy within 10–15 years and one tree per 6 required spaces interior ratio, etc.) § 17.76.040–060 .

If my lot is in a Planned Development (‑PD), which standards apply?

A PD overlay sets project‑specific standards; the PD plan and Table 2B control minimum lot area, densities and any deviations — design review enforces the approved PD plan rather than the general base zone where the PD makes specific changes § 17.48.040 .

Who enforces the design review conditions and what happens if I don't comply?

The Community Development Director enforces the zoning title; site plan approval via design review follows the same revocation/expiration rules as other permits (see § 17.24.070(A) and § 17.36.060) and approvals can be revoked or expire if conditions are not met .

Can I get informal comments before filing a formal design review?

Yes — the code allows an optional conceptual design review prior to formal site plan submission; conceptual review is advisory only and does not bind later decisions § 17.36.070 .

Do I need to follow Title 24 when I submit materials for design review?

Design review governs appearance, siting, and landscape; compliance with the California Building Standards Code (Title 24) is required for building permits but is a separate review layer from design review — coordinate both but note the code’s design review criteria address aesthetics and site design (not building code compliance). Verify specific building‑code intersections with the building department and plan check — building code matters are outside Chapter 17’s design review criteria (verify with the jurisdiction) .
