Santa Cruz, CA Zoning

Euclidean-zoning. 19 districts · 9 overlays · 6 applicable state preemptions.

Overview

Code type
euclidean
Naming convention
letter-code

Santa Cruz uses a letter-code system: R-S (Residential Suburban), R-1 (Single-Family), R-L/R-M/R-H (multifamily density tiers), R-T (Tourist Residential with A/B/C/D/E subdistricts), commercial districts (C-C, C-T, C-N, C-B), P-A (Professional/Admin), I-G (Industrial), CBD, plus parks/public/agricultural/open space districts and numerous overlay districts. Numbers in R-1 subdistricts (R-1-10, R-1-7, R-1-5) encode minimum lot size in thousands of sq ft. The coastal zone overlay (CZ-O) covers substantial portions of the city.

Worth knowing
  • CBD standards incorporated by reference from Downtown Plan Chapter 4 (§24.10.2301, Ord. 2025-11) — specific height/FAR/setback figures require reading the Downtown Plan separately; recorded as partial in CBD district entry
  • R-1 subdistricts encode minimum lot size in the district name (R-1-10 = 10,000 sf, R-1-7 = 7,000 sf, R-1-5 = 5,000 sf) — naming_convention: letter-code with lot-size-encoded numeric suffix
  • R-S suburban subdistricts use acre-based lot minimums (RS-10A, RS-5A, RS-2A, RS-1A); in practice largely absent from the urban core

State preemptions

CA Density Bonus Law — Gov Code §65915applies
Qualifying condition
Density bonus applies citywide to any qualifying affordable housing project in any residential or mixed-use zone. No population threshold. Santa Cruz is a standard city with residential zoning; law applies universally. Checked: Santa Cruz has R-L, R-M, R-H, C-C, C-T, CBD districts all eligible for density bonus projects. HCD status: housing element certified In compliance (reviewed 2023-12-20). Law applies regardless of compliance status.
California SB 9 — HOME Act (Gov Code §66411.7–66411.8)applies
Qualifying condition
SB 9 applies to R-1-5, R-1-7, R-1-10, RS subdistricts (res_sf category). Trigger: parcel in single-family zone, not in historic district, fire hazard zone, flood zone AE, or coastal zone. Note: Santa Cruz has a Coastal Zone overlay (CZ-O) — SB 9 is EXCLUDED from coastal zone parcels per the trigger predicate. Applies to SF parcels outside the CZ-O boundary. Population: 62,956 (2020 Census) — no population threshold for SB 9. Applies = true (partial — coastal zone exclusion reduces scope).
California AB 2097 — Parking Mandate Elimination Near Transit (Gov Code §65863.2)applies
Qualifying condition
Santa Cruz Metro serves the city with local bus service including routes with >15-min peak frequency; Highway 17 Express connects to San Jose. UCSC campus routes provide high-frequency service. City has qualifying transit stops within ½ mile of substantial portions of the city's commercial and multifamily zones. Transit proximity flag: has_qualifying_transit_stop_under_ab2097 = true based on Santa Cruz Metro frequent routes (Lines 3, 9, 10, 16, 17, 35 operating with regular headways). Parking mandates waived on a per-parcel basis within ½ mile of qualifying stop.
California SB 423 — Streamlined Multifamily Approval (Gov Code §65913.4)applies
Qualifying condition
HCD SB 35/423 Determination dataset (hcd-ca-lookup.json): Santa Cruz SB 423 tier = '50%'. Threshold: streamlined ministerial approval for qualifying projects ≥50% affordable. HCD sb35 data: lower_pct_complete=132.2%, above_mod_pct_complete=116.0%, 50pct_flag=Yes (planning period: Half 5th). Housing element: compliance_status=In (reviewed 2023-12-20). Applies to residential and mixed-use zones (R-L, R-M, R-H, C-C, C-T, CBD, MU subdistricts). Excluded from coastal zone and very high fire hazard zones. SB 423 sunset: 2036-12-31.
California AB 2011 — Affordable Housing and High Road Jobs Act (Gov Code §65912.100 et seq.)applies
Qualifying condition
Applies to commercially-zoned parcels (C-C, C-T, C-N, P-A, CBD) in Santa Cruz for 100% affordable projects or corridor-located mixed-income projects. No population threshold. Santa Cruz has commercial zones on Mission Street, Ocean Street, and other corridors qualifying as 'urban corridors.' Prevailing wage required. Applies = true for qualifying commercial sites. Coastal zone exclusion may reduce scope for beachfront commercial parcels.
California ADU / JADU By-Right (Gov Code §66411.7–66411.8)applies
Qualifying condition
ADU/JADU by-right applies to all residential and mixed-use parcels statewide. Santa Cruz has R-S, R-1, R-L, R-M, R-H residential zones, all qualifying. Population 62,956 (2020); no population threshold. ADU parking waived within ½ mile of transit (Santa Cruz Metro), in historic districts (H-O overlay areas), or for ADUs within existing structures. Applies = true citywide on residential and mixed-use parcels.
Non-applicable laws (2)
California Builder's Remedy (Gov Code §65589.5(d)(5))does not apply
Qualifying condition
Builder's Remedy triggered only when housing element is NOT certified by HCD. HCD lookup data shows Santa Cruz housing_element compliance_status = 'In' (reviewed 2023-12-20, 6th Cycle). Builders_remedy_subject = false per hcd-ca-lookup.json. Builder's Remedy does NOT apply.
California SB 10 — Local Upzoning Authorization (Gov Code §65913.5)does not apply
Qualifying condition
SB 10 is an opt-in local tool, not a state preemption. The trigger_predicate is 'never' in the CA overlays file — it applies only when a city has affirmatively adopted an SB 10 resolution. No evidence found that Santa Cruz has adopted an SB 10 resolution. Applies = false (opt-in not triggered).

Quirks & notes

  • CBD standards incorporated by reference from Downtown Plan Chapter 4 (§24.10.2301, Ord. 2025-11) — specific height/FAR/setback figures require reading the Downtown Plan separately; recorded as partial in CBD district entry
  • R-1 subdistricts encode minimum lot size in the district name (R-1-10 = 10,000 sf, R-1-7 = 7,000 sf, R-1-5 = 5,000 sf) — naming_convention: letter-code with lot-size-encoded numeric suffix
  • R-S suburban subdistricts use acre-based lot minimums (RS-10A, RS-5A, RS-2A, RS-1A); in practice largely absent from the urban core
  • Performance Overlay zones (I-G/PER, I-G/PER-2, R-T(B)/PER, R-T(C)/PER) are specialized industrial/tourism performance variants; dimensional standards in Parts 16A/16B/7B.1/7C.1 not extracted due to budget constraints — recorded as not_captured
  • Tourist Residential subdistricts (R-T(A) through R-T(E)) cover the beach/boardwalk area; R-T(C) Beach Commercial and R-T(D) Beach Residential are coastal-specific; standards in Parts 7A-7E not extracted — partial
  • Coastal Zone: Santa Cruz is almost entirely within the California Coastal Zone; CZ-O overlay applies broadly; Local Coastal Program (LCP) is certified by CA Coastal Commission and governs all coastal development permits
  • SB 9 coastal zone exclusion significantly limits lot-split/duplex pathway for beachfront and coastal-proximate parcels
