Last reviewed: July 6, 2026

Overview

In unincorporated Santa Cruz County, “Design Review” is the County’s site, architectural, and landscape review applied to certain projects that require a zoning site development permit or coastal development permit. The rules live in Title 13 of the Santa Cruz County Code, primarily in the Design Review chapter (§ 13.11.010–13.11.080) and cross-reference district standards, development standards, and Coastal Zone provisions. Design review evaluates building and site design, environmental compatibility, and conformance with the County’s Design Guidelines where applicable, and it is integrated into the site development permit process in § 13.11.050 .

The core trigger: if your project needs a site development permit and falls into the categories listed in § 13.11.040, you’re in design review—unless a specific exemption or Planning Director waiver applies (see § 13.11.040(B)) .

What is covered by Santa Cruz County’s Design Review chapter

  • Purpose and scope: Establishes design review to implement the General Plan/LCP and guide residential, commercial, industrial and public facility projects; identifies when design review is required; integrates County Design Guidelines; and sets standards and limited exceptions (§ 13.11.010–13.11.025) .
  • When design review is required: Residential thresholds (e.g., “large homes,” multifamily), subdivisions, and all new or exterior-remodel commercial, mixed-use, industrial, or public facility projects; agriculturally related uses in CA, A, and RA are exempt (§ 13.11.040(A)) .
  • Process timing: Occurs during initial completeness review (first 30 days) with possible second/third rounds if plans are revised or CEQA mitigation changes design (§ 13.11.050) .
  • County Design Guidelines: Apply to new multifamily (3+ units) and commercial/mixed-use projects, including exterior remodels/additions over 500 sf, within the Urban and Rural Services Lines; used as review criteria in design review (§ 13.11.060) .
  • Design standards: Environmental site planning, coordinated development, signage, lighting, waste/recycling, and landscaping standards guide approval (§ 13.11.070) .
  • Flexibility: Case-by-case exceptions to design standards/guidelines may be granted where they better achieve chapter objectives (§ 13.11.080) .

How design review is applied across districts in unincorporated areas

Below is a district-by-district view of how design review intersects with purposes, typical uses, and key standards where established in the retrieved materials.

R-1 Single-Family Residential

  • Purpose and typical uses: Single-family neighborhoods; single-family dwellings are the typical primary use (context from County zoning framework). Large-home projects (5,000 sf+) trigger design review under § 13.11.040(A)(1)(b), which references § 13.10.324 .
  • Design review applicability:
    • New residences or ≥500 sf additions on sensitive sites or in coastal special communities require DR (§ 13.11.040(A)(1)(a)) .
    • New or remodeled single-family homes 5,000 sf+ require DR (§ 13.11.040(A)(1)(b)) .
  • Key dimensional standards: Not found in retrieved materials. Verify with the Development Standards and § 13.10.500–13.10.600 as applicable (general reference; specific R-1 standards not retrieved) .

RM and RF Multifamily Residential

  • Purpose and typical uses: Multifamily housing; RM sub-districts scale from RM-1.5 up to RM-9; RF appears in the multifamily chart context.
  • Design review applicability: Residential projects with 3+ units require DR (§ 13.11.040(A)(1)(c)); County Design Guidelines apply to new multifamily of 3+ units within USL/RSL (§ 13.11.060(B)) .
  • Key dimensional standards (illustrative selections from the Multifamily Dimensions Chart):
    • FAR: RM-3 to RM-4 = 0.6; RM-4.5 = 0.5; RM-5 to RM-6 = 0.5; RM-6.5 to RM-9 = 0.5; RF = 1.1 (<30 du/ac) or 1.5 (≥30 du/ac) (see table notes) (§ 13.10.323, Table) .
    • Setbacks: Front 15–20 ft depending on RM sub-district; side interior 5–8 ft; rear 15 ft; third-story stepbacks may apply (§ 13.10.323, Table) .

C Commercial Districts

  • Purpose and typical uses: Retail, services, offices; commercial centers. County references to “commercial districts” and “commercial uses” are broad; district-by-district names were not retrieved.
  • Design review applicability: All new commercial construction or exterior remodels go through DR when a site development permit is required (§ 13.11.040(A)(3)), and commercial districts confirm DR applies to some SDPs (§ 13.10.333(A)(1)) .
  • Special corridor standards: The Pleasure Point Commercial Corridor sets caps and stepbacks (e.g., max 20,000 sf tenant space; third stories interior; sidewalk width and setbacks) (§ 13.10.333(D)) .
  • Key dimensional standards: Not comprehensively retrieved; verify per commercial district standards and Development Standards. Other applicable standards: signage (§ 13.10.580–13.10.587), Parking Chapter 13.16 .

M-1, M-2, M-3 Industrial Districts

  • Purpose and typical uses:
    • M-1 Light Industrial: assembly and similar non-nuisance uses.
    • M-2 Heavy Industrial: lumber mills, major manufacturing/processing.
    • M-3 Mineral Extraction: rock, sand, gravel, other mineral resources (purposes listed in § 13.10.341) .
  • Design review applicability: Industrial districts confirm DR is required for some SDPs under § 13.11.040–13.11.080 (§ 13.10.343(A)(1)) .
  • Key dimensional/operational notes: Additional industrial standards (e.g., nuisance control, smoke limits) appear in § 13.10.344; cross-reference general standards and parking (§ 13.10.500–13.10.600, Chapter 13.16) (§ 13.10.346, Table) .

PF Public and Community Facilities

  • Purpose and typical uses: Public/quasi-public institutions and community facilities (§ 13.10.361) .
  • Design review applicability: New construction or exterior remodels are subject to DR via § 13.11.040(A)(3); PF chapter recognizes SDPs and references design review (§ 13.10.363(A)) .
  • Key dimensional standards (PF) shown below.

PF key site and structural dimensions (selected)

Standard Requirement Code Reference
Max height 3 stories (40 ft) § 13.10.363(B), Table 13.10.363-1
Lot coverage 40–95% § 13.10.363(B), Table 13.10.363-1

Abutting residential/ag Min 10–15 ft, with extra third-floor stepbacks § 13.10.363(C)

PR Parks, Recreation and Open Space

  • Purpose and typical uses: Preserves open space and supports low-intensity commercial recreation and park facilities (§ 13.10.351) .
  • Design review applicability: The PR district’s “Other Standards” table explicitly references design review and site development (§ 13.10.356, table includes “Design review and site development: § 13.11”) .
  • Key dimensional standards: Not found in retrieved materials. Verify with district charts.

CA, A, RA Agriculture and Resource Districts

  • Purpose and typical uses: Agriculture and related resource uses.
  • Design review applicability: All agriculturally related uses and structures in CA, A, and RA are exempt from design review (§ 13.11.040(A)(5)) .
  • Site development permits: Agricultural development permit thresholds appear in the SDP chart (e.g., EHA/farmworker housing; agricultural support facility thresholds) (§ 13.11.037, Table excerpts) .

TP Timber Production

  • Purpose and typical uses: Timber production; accessory structures addressed in the SDP chart.
  • Design review applicability: If a TP project otherwise meets a DR trigger (e.g., exterior remodel of a commercial building on a mixed-use site), DR would apply; otherwise, accessory structures to timber production can be permitted by right per the SDP chart (§ 13.11.037, Table) .

Coastal Zone overlay and special areas

  • Coastal Zone: Coastal development permits are required as specified in Chapter 13.20; Coastal Zone applies in the unincorporated Coastal Zone and is applied with zoning and other code provisions (§ 13.20.020) . When in the Coastal Zone, design review happens alongside CDP review.
  • Coastal special communities and sensitive sites: These designations trigger DR for certain residential projects; “sensitive site” is defined in § 13.11.030 and includes scenic areas, coastal bluffs, ridgelines, and other mapped resources . For corridor- or village-specific design, some areas (e.g., Pleasure Point) have additional guidance embedded in County standards or the Design Guidelines (§ 13.10.333(D); § 13.11.060) .

What design review looks at (high-level standards)

  • Environmental site and building design: Coordinate circulation, encourage clustering where appropriate (especially in rural/sensitive areas), retain natural features, transition massing near lower-density neighbors, and protect scenic resources (§ 13.11.070(B)) .
  • Signage: Must meet sign regulations and be consistent with design principles; freestanding signs integrated with site/building design (§ 13.11.070(C)(3); signs in § 13.10.580–13.10.587) .
  • Lighting: Direct light on-site; shield sources; 15-ft max light poles for parking/circulation (§ 13.11.070(C)(4)) .
  • Waste/recycling: Provide appropriately sized and accessible waste and recycling enclosures (with weather protection) for commercial, industrial, public facility, and multifamily (§ 13.11.070(C)(2)) .
  • Landscaping: Site and parking-lot landscaping must meet the County’s principles and water-efficient landscape standards (§ 13.11.070(D)) and Chapter 13.13; see also Landscaping and Screening .
  • Parking/circulation: Apply Chapter 13.16 standards; coordinate shared access and guest parking where required; see Parking (§ 13.16.060 referenced via § 13.11.070(C)(5)) .

Process integration and approvals

  • Design review is built into the site development permit workflow, with initial review during the first 30-day completeness window and subsequent reviews if plans change or CEQA mitigation requires redesign (§ 13.11.050) .
  • The Planning Commission, Zoning Administrator, and Planning staff are charged with administering design review as established in § 13.11.010(F) .
  • In commercial and industrial districts, the code reiterates that design review is required for some SDPs and cross-references Chapter 13.11 (§ 13.10.333(A)(1); § 13.10.343(A)(1)) .

Checklist

  • Confirm the site is in unincorporated Santa Cruz County and identify base zoning and any Overlay Districts.
  • Determine if a site development permit (and/or coastal development permit) is required for the work scope (§ 13.11.035, § 13.11.037; § 13.20.020) .
  • Check DR triggers in § 13.11.040 (large-home threshold; multifamily 3+ units; commercial/industrial/public projects; subdivisions; sensitive sites/coastal special communities) .
  • If multifamily or commercial/mixed-use within USL/RSL, prepare to meet the Santa Cruz County Design Guidelines (§ 13.11.060(B)) .
  • If ADU-only, confirm DR exemption and follow California ADU law and local ADU standards (DR exemption in § 13.11.040(A)(1)(c)) .
  • Align plans with design standards in § 13.11.070 (site planning, transitions, signage, lighting, waste/recycling, landscaping) and applicable Signage and Parking rules .
  • If in the Coastal Zone, integrate CDP requirements (§ 13.20.020); if in a corridor/village with special guidance, incorporate those standards (e.g., Pleasure Point, § 13.10.333(D)) .
  • Consider whether a minor exception or variance is needed for objective standards (see Variances and Exceptions; references in code to § 13.10.230–.235) .
  • Be prepared for iterative review per § 13.11.050; final conditions will be binding and enforced (§ 13.10.280(B)) .

Risks & Ambiguities

Issue Why it matters What to verify
Is the site “sensitive” or in a “coastal special community”? Triggers DR for ≥500 sf single-family additions/new homes Confirm mapping and definitions under § 13.11.030; verify with County GIS and Planning staff
Large-home threshold New/remodeled SFD at 5,000+ sf requires DR Confirm gross floor area calculation and applicability under § 13.11.040(A)(1)(b) and § 13.10.324
Which commercial/industrial SDPs require DR DR attaches to new builds/exterior remodels Confirm your scope meets § 13.11.040(A)(3) and district cross-references in § 13.10.333 / § 13.10.343
Applicable design guidelines Some corridors/areas have added guidance Check County Design Guidelines applicability (§ 13.11.060(B)) and any special corridor provisions like Pleasure Point (§ 13.10.333(D))
Agricultural exemption limits CA, A, RA uses/structures exempt from DR Confirm your use is “agriculturally related” per § 13.11.040(A)(5)
Coastal + DR sequencing CDP adds procedures and findings Coordinate CDP under § 13.20.020 with DR timing in § 13.11.050
Submittal requirements Historical DR submittal section repealed Use current County submittal checklists; § 13.11.051 repealed—ask staff for current submittals

Plain-English Summary

If you’re building or significantly remodeling in unincorporated Santa Cruz County, you may need design review—especially for multifamily, commercial/industrial/public projects, large single-family homes, subdivisions, or work on sensitive/coastal-community sites. Design review happens within the site development permit process, checks your project against County design standards and guidelines, and can include fine-tuning of site design, parking, signage, lighting, and landscaping. ADUs are exempt. Coastal Zone projects add CDP steps. If something seems off with strict standards, limited flexibility exists case-by-case.

Frequently asked questions

Do I need design review for a new single-family home in unincorporated Santa Cruz County?

Yes if the house is 5,000 square feet or larger, or if it is on a sensitive site or within a coastal special community; see the triggers in § 13.11.040(A)(1)(a)–(b) (with large-home provisions tied to § 13.10.324). Smaller homes outside those areas typically avoid DR unless other approvals pull it in.

Are ADUs subject to design review in unincorporated areas?

No. Accessory dwelling units are exempt from design review under § 13.11.040(A)(1)(c). Still, ADUs must meet County ADU standards and state rules.

What counts as a “sensitive site” for design review purposes?

“Sensitive site” includes mapped scenic areas, coastal bluffs, ridgelines/ridgetops, scenic road viewsheds, and other areas where development could impact public views or sensitive resources, as defined in § 13.11.030. These locations trigger DR for certain residential additions/new homes. Verify with County GIS.

I’m doing a commercial exterior remodel—will I need design review?

Yes. All new commercial construction and remodels involving exterior alterations require design review where a site development permit is required, per § 13.11.040(A)(3), and commercial district standards confirm that DR applies to some SDPs in § 13.10.333(A)(1).

How does design review interact with the Coastal Zone?

In the Coastal Zone, coastal development permit requirements apply alongside zoning. In case of conflict, the more protective coastal provisions prevail; see § 13.20.020. Design review occurs within the permit process per § 13.11.050.

Can design standards be adjusted if my site has constraints?

Possibly. The County may allow flexibility or exceptions to the design standards and Design Guidelines when it better achieves chapter objectives or due to special site circumstances, per § 13.11.080. This is case-by-case and not a precedent.

Do agriculturally related buildings need design review?

Not in the CA, A, or RA districts. Agriculturally related uses and structures in these zones are exempt from DR under § 13.11.040(A)(5). Confirm your use qualifies.

What does design review look at—signs, lighting, and landscaping too?

Yes. Standards address coordinated site planning, signage conformance, lighting that is shielded and directed on-site, waste/recycling enclosures, and landscaping that meets water-efficient standards, per § 13.11.070(C)–(D).
