Santa Cruz County Zoning, Planning & Building Codes

Last reviewed: July 6, 2026

Overview

This page orients you to how land use is regulated in the unincorporated areas of Santa Cruz County. The County’s zoning rules live in the Santa Cruz County Code’s Title 13 Planning and Zoning, most notably the Zoning Ordinance at § 13.10; they implement the General Plan/LCP and work alongside dedicated chapters for design review, parking, and the Coastal Zone. In the Coastal Zone, a separate chapter governs permitting and can be more protective than standard zoning. This guide explains how the code is organized, the district structure, core development standards, overlays and specific-corridor rules, the permit path, and how state housing laws for ADUs, SB 9 and density bonus interact with County regulations.

The Coastal Zone chapter applies in addition to zoning, and if there’s a conflict, the coastal rules or the most protective standard prevails over other regulations to safeguard coastal resources. See § 13.20.020(C) .

How Santa Cruz County’s code is organized

• The Zoning Ordinance states its purposes and scope at § 13.10.110–130, implementing the General Plan/LCP and regulating use, site development, signs, and more .
• District regulations are grouped by family (residential, commercial, industrial, agricultural, resource, public/open space, special use), each with use charts and site standards. The County maintains the official zoning map per § 13.10.180 and procedures for map amendments in § 13.10.185 .
• Countywide site and dimensional rules you’ll look for under Santa Cruz County Development Standards generally live in § 13.10.500–13.10.600, and variances/minor exceptions are at § 13.10.230–235 (see below) .
• Design review and Site Development Permits (SDPs) are administered in Chapter 13.11; the chapter establishes when SDPs and design review apply, the review process, adopted Design Guidelines, and design standards (§ 13.11.020, § 13.11.035, § 13.11.050, § 13.11.060–070) .
• Parking and circulation standards, including vehicle and bicycle parking and access/circulation design, are in § 13.16 (e.g., § 13.16.010, § 13.16.040, § 13.16.060, § 13.16.090) .
• Coastal development permitting lives in § 13.20; it applies to all coastal-area development and can supersede zoning where more protective (§ 13.20.010–030) .
• Permit processing mechanics (approvals, findings, amendments, conditions) are in Title 18; Chapter 18.10 is repeatedly cross-referenced for use permits, SDPs, conditions, and appeals (e.g., § 13.10.220, § 13.11.035(B)) .

Zoning district families

Santa Cruz County’s zoning districts are mapped from General Plan/LCP designations via the Zoning Implementation Table at § 13.10.170-1, and include the following families used in unincorporated areas :

• Residential: RA (Residential Agriculture), RR (Rural Residential), R-1 (Single‑Family), RB (Ocean Beach Residential), RM (Multifamily), RF (Residential Flex) — purposes and use charts at § 13.10.321–322 .
• Commercial: C-1 and C-2, with special mixed-use and corridor rules at § 13.10.334 (e.g., density up to 45 du/ac; Pleasure Point corridor standards) .
• Industrial: M‑1 (Light), M‑2 (Heavy), M‑3 (Mineral Extraction), purposes/standards at § 13.10.341–343 .
• Agricultural/Resource: A (Agriculture), CA (Commercial Agriculture), AP/A‑P (Agricultural Preserve variants), TP (Timber Production) — standards and cross‑references at § 13.10.319 and TP uses at § 13.10.372 .
• Public/Open Space: PR (Parks, Recreation & Open Space) and PF (Public & Community Facilities) at § 13.10.351–356 and § 13.10.365–366 .
• Special Use: SU, with development standards and cross‑references to SDPs and CDPs at § 13.10.383 .
• Combining/Overlay districts: The code lists combining districts at § 13.10.400 et seq., such as SP (Salamander Protection) at § 13.10.481–483, AIA (Airport) at § 13.10.437–438, R (Regional Housing Need), W (Watsonville Utility Prohibition), and -Min (Ministerial Combining District for certain affordable multifamily) in Table 13.10.400‑1 .

Also note: “Villages” (e.g., Aptos, Ben Lomond, Boulder Creek, Felton, Seacliff, Soquel) can have adopted specific or area plans that layer design criteria; “village” is defined at § 13.11.030(J), and projects must follow any adopted special plan standards per § 13.11.035(E)(3) . See Santa Cruz County Overlay Districts for more.

Citywide development standards

The County uses district-specific site and structural dimensions, plus countywide standards and exceptions.

• Residential multifamily and RF example standards (excerpt from the County’s chart at § 13.10.323):
  • RF: front setback 10 ft; interior side 5 ft/5 ft; rear 15 ft; third-story stepback requires at least 10 ft for 50% of exterior walls; FAR allowed 1.1–1.5 depending on density; no max lot coverage listed for RF in this chart .
  • RM-5 to RM-6: front setback 20 ft; side 5 ft/8 ft; rear 15 ft; garage/carport entry 20 ft; max lot coverage 45%; FAR 0.5 .
  • Garage/carport entries must observe 18–20 ft setbacks depending on RM subdistrict; third stories in lower‑intensity RM tiers require 10 ft stepbacks for 50% of walls, while higher‑intensity RM tiers may not require it (see chart notes) .
  • FAR is calculated per definitions and rules in § 13.10.510 and § 13.10.700, with noted exemptions in § 13.10.323(F)(8); accessory structures and ADUs follow § 13.10.611 and § 13.10.681 .
• Commercial/mixed-use: Mixed residential over commercial can reach a base density of 45 du/ac (additional units via density bonus per Chapter 17.12), with corridor-specific standards (see Pleasure Point below) and an FAR parking exemption if ≥75% of parking is in structured/podium/underground formats (§ 13.10.334(A), (E)) .
• Corridor/special area examples:
  • Pleasure Point commercial corridor standards (e.g., minimum sidewalk widenings, no height exceptions, third-story placement, and adjacency setbacks) are codified at § 13.10.334(D) .
• Countywide standards, exceptions, and enforcement:
  • General site standards are aggregated at § 13.10.500–600, and fire‑safe setbacks may increase in State Responsibility Areas (Title 14, Cal. Code Regs., Ch. 7) as flagged in § 13.10.334(C) notes .
  • Minor exceptions allow limited relief such as up to a 5% height increase, 15% setback reduction, and specific FAR/coverage adjustments (§ 13.10.235) — see variances and exceptions .
  • Variances follow findings at § 13.10.230; violations of setbacks/height/coverage are enforceable per § 13.10.277–280 .

Parking and circulation

• Vehicle parking purpose and framework are at § 13.16.010; design standards (location of parking, allowance for off‑site/shared parking via recorded easements) at § 13.16.060(A)(1)–(3); interior roadway and guest‑parking rules (e.g., 20% guest parking for certain interior roadways) at § 13.16.090(H)(3) .
• Bicycle parking is required for new/intensified uses with quantities and rack types in § 13.16.040; compact space allowances appear in § 13.16.050 (e.g., up to 40% compact stalls for lots ≥81 spaces) . Link: see parking.

Specific plans & overlays

• Coastal Zone: Chapter 13.20 establishes the CDP process, findings, noticing/appeal, and the rule that coastal regulations apply with zoning and prevail if more protective (§ 13.20.010–030) .
• Corridor standards: The Pleasure Point commercial corridor standards are codified at § 13.10.334(D) (tenant space size, sidewalk widths, height exceptions prohibited, adjacency setbacks) .
• Combining/overlays: Examples include SP Salamander Protection (§ 13.10.481–483), AIA Airport (§ 13.10.437–438), R Regional Housing Need (§ 13.10.475–477), and -Min Ministerial Combining District (§ 13.10.494–497) — see Table 13.10.400‑1 and overlay districts .
• “Village”/area plans: Defined at § 13.11.030(J); SDPs must comply with any adopted special plan standards per § 13.11.035(E)(3) .

Building permits & review

• Determine use permissions in your base district (e.g., residential uses at § 13.10.322; industrial at § 13.10.343). Some uses are permitted by right, others need a Use Permit; processing and findings reference Chapter 18.10 (§ 13.10.220, § 13.10.322(B)) .
• Most physical development that is not purely ministerial will need a design review-linked Site Development Permit (SDP) per § 13.11.035; procedures and timing are at § 13.11.050. The County applies adopted Design Guidelines to multifamily/mixed‑use/commercial within the service lines (§ 13.11.060), and § 13.11.070 provides design standards (e.g., coordinated parking/landscaping, sensitive-site clustering) .
• Coastal properties often also need a CDP under § 13.20 (and ADUs/JADUs have tailored coastal processing; see below) .
• Building permits are issued under the California Building Standards Code (Title 24). Zoning compliance is checked before or alongside building permit issuance; enforcement tools for nonconforming structures and permit conditions are at § 13.10.262 and § 13.10.276–280 .

State housing law in Santa Cruz County

• ADUs/JADUs:
  • Ministerial approval is required under timelines aligned with state law: ADU/JADU applications must be approved or deemed incomplete within 60 days when submitted independent of a new primary dwelling (§ 13.10.681(H)(2)); ADU/JADU permits are otherwise ministerial per Gov. Code 65852.2, as reflected in § 13.10.681(H)(1). Coastal processing may still require a CDP with coastal noticing/appeals if no exemption applies (§ 13.10.681(H)(1)(a); cross‑references § 13.20.050–110) .
  • The County details fee treatment (no “impact fees” for units under 750 sq ft) in § 13.10.681(H)(3) and provides special processing rules for PR and TP zones (§ 13.10.681(H)(1)(a)–(c)) .
• SB 9 two‑unit developments and urban lot splits:
  • Two‑unit developments are established in § 13.10.327 with objective standards and a 60‑day approval window; denial is limited to objective noncompliance or specified public‑safety conflicts (mirroring Gov. Code 65589.5(d)(2)) (§ 13.10.327(C)–(F)) .
  • Urban lot splits are in § 13.10.328 with objective parcel standards (e.g., minimum 2,400 sq ft existing parcel; newly created smaller parcel at least 1,200 sq ft; larger parcel ≤60% of the original), and no discretionary review other than a CDP in the Coastal Zone (§ 13.10.328(D)–(E)). Up to two units per lot are allowed; a maximum of four units can result from an SB 9 lot split (§ 13.10.327(D)(7)) .
• Density Bonus Law:
  • The County cross‑references its density bonus chapter (Chapter 17.12) for mixed‑use/multifamily in commercial districts. Additional units may be allowed, including in the Coastal Zone when consistent with the Coastal Act and the LCP (§ 13.10.334(A)(1)(a)–(b)) .
• Renter protections:
  • Local rent-control provisions were not found in the retrieved materials. See California housing laws for state requirements (e.g., AB 1482) and verify any County-specific rent ordinances with the jurisdiction. Not found in retrieved materials.
