Santa Clarita Zoning, Planning & Building Codes

Last reviewed: July 3, 2026

Overview

Santa Clarita’s land-use rules are codified in Title 17 (the Zoning Code); the title frames the Unified Development Code together with Title 16 and implements the General Plan across the city § 17.01.010 and § 17.01.030 . The code organizes uses into zone families (residential, commercial, industrial, mixed‑use, non‑urban, open space, specific- and corridor-plans) and attaches citywide development standards and overlays to those zones § 17.31.010 . This page explains how the code is laid out, the principal zone families and typical numeric controls (setbacks/height/FAR/coverage/parking), the main overlays and specific plans that matter in Santa Clarita, the permit/review path, and how State housing law (ADUs and two‑unit rules) is implemented locally.

How Santa Clarita's code is organized

• Title and purpose — Title 17 is the City’s Zoning Code and forms the Unified Development Code together with Title 16 § 17.01.010 ; the code must be applied consistent with the General Plan § 17.01.030 .
• Divisions and chapters — The code is structured into Divisions (procedures, zones, use classifications, development standards, overlays, special districts, etc.). The Zoning Designation / purpose statement and the list of zone families are in § 17.31.010 .
• Permit types and review classes — Applications are grouped by Class (Class I–VII); ministerial approvals are Class I, many administrative/design reviews and permits are Class II, minor use/adjustments are Class III, conditional use/variances and tentative maps are Class IV, and legislative actions (specific plans, zone changes) are Class VII § 17.06.020 . The Director, Hearing Officer, Planning Commission and City Council have the decision roles spelled out in Chapter 17.02 § 17.02.050 and § 17.02.030 .
• Post‑decision & effective dates — Approvals become effective per the timed rules (e.g., § 17.06.170 effective date; scope of what the approval covers in § 17.06.180) and permits may carry conditions and performance guarantees § 17.06.170 § 17.06.180 .
• Where to find numeric standards — Lot-by-lot and building controls live primarily in the zone writeups (Chapters 17.32–17.34 for non‑urban, residential, commercial/industrial zones) and in Division 6 property/ development standards (Chapter 17.57 and related sections) § 17.32.010 § 17.57.025 . For citywide design rules and objective standards consult the development-standards chapter and the Community Character & Design Guidelines (see development standards).

Zoning district families (citywide snapshot)

The code explicitly groups zones into families; the code lists the families as non‑urban, urban residential, commercial, industrial, mixed‑use, open space, public/institutional, specific plan, and corridor plan zones § 17.31.010 .

Representative Santa Clarita zones and the controlling citations:

• Non‑urban: NU1 (very low density/rural lots — front setback 20 ft, side 5/5 ft, max height 35 ft) § 17.32.010 .
• Urban residential series: UR1–UR5 (gradations from low to high density); example UR5: max density 30 units/acre, front setback 20 ft, max height without CUP 35 ft § 17.33.050 .
• Commercial / regional: CC (community commercial) and CR (regional commercial). Example CR: non‑residential FAR 2.0, maximum lot coverage without CUP 90%, max height 35 ft and residential setbacks 25 ft § 17.34.030 .
• Business park / industrial: BP (FAR 2.0, lot coverage 90%) and I (industrial; FAR 1.0, lot coverage 90%) — standard right‑of‑way setbacks and 35 ft typical base height § 17.34.040 § 17.34.050 .
• Mixed‑Use and overlays: the code uses overlay zones (see next section) and a dedicated MU—Mixed Use Overlay with tailored incentives (reduced parking, higher heights, density incentives) § 17.38.050 .
• Use rules & parking: permitted uses and parking requirements are set in Division 5 (Use Classifications and Required Parking) and in zone tables; ADUs, accessory uses and parking exceptions are spelled out in Chapter 17.57 and the use tables § 17.41.010 § 17.57 (ADU and related rules) .

Citywide development standards — what to expect

High-level rules that apply across zones (citations below point to the chapters that collect these standards):

• Setbacks and lot coverage — Most zones list numeric setbacks and lot‑coverage caps in the zone write‑up; e.g., residential zones commonly use 20 ft front setback and 5 ft side setbacks in single‑family zones § 17.32.010 . ADU and two‑unit rules create statutory limited exceptions (see ADU and two‑unit sections below) § 17.57.025 .
• Height — Many base zones cap typical building heights at 35 ft without a CUP; some overlay incentives raise allowable heights (for example the JC overlay allows office buildings 3–5 stories or industrial up to 55 ft under prescribed conditions) § 17.34.030 § 17.38.015 .
• FAR / lot coverage — Commercial/business districts publish FAR caps (e.g., CR FAR 2.0, BP FAR 2.0, lot coverage up to 90% in these zones) § 17.34.030 .
• Parking — Required parking standards live in Division 5 and are adjusted in overlays and specific plans (the MU overlay explicitly allows reduced parking and mixed calculations; ADUs have their own parking exceptions) § 17.41.010 § 17.38.050 . For project‑level parking procedures and fees see the City’s parking menu.
• Landscaping, oak tree protection, ridgelines and hillside controls — citywide environmental and design controls (oak tree preservation, hillside development and ridgeline overlays) are applied through Chapter 17.51 and related sections § 17.51.040 . See landscaping and screening for policy references.
• Design review / objective design standards — many projects require objective design compliance with the Community Character and Design Guidelines; Architectural/Design Review appears in Class II (administrative) approvals and in overlay/specific plan rules § 17.06.020 § 17.23.030 . See the City’s design review page for practical steps.

Specific plans & overlays (what changes rules on a parcel)

• Specific plans and corridor plans are explicit zone families and are legislative (Class VII) actions when adopted § 17.31.010 § 17.06.020 . Use the zoning map and the specific plan text to see the site‑level rules.
• Major overlay programs you will encounter in Santa Clarita:
  • MU — Mixed Use Overlay (incentives: reduced parking, increased heights and density, accelerated review; applies on mapped corridors and requires a minor use permit) § 17.38.050 .
  • PD — Planned Development Overlay (extra discretion for underutilized or vacant parcels; redevelopment triggers CUP for >50% valuation) § 17.38.060 .
  • RP — Ridgeline Preservation (applies to mapped ridgelines; requires special exhibits and potential ridgeline alteration permits) § 17.38.070 .
  • HS — Homeless Shelter Overlay (mapped areas where shelters are permitted consistent with SB 2 requirements) § 17.38.010 .
  • VS / VDS — Vehicle Services and Vehicle Dealer Sales Overlays (channel auto uses to mapped corridors with supplemental standards) § 17.38.100 § 17.38.090 .
  • JC — Jobs Creation Overlay (incentives and minimum building types targeted to growth industries) § 17.38.015 .
  • SMHP — Senior Mobilehome Park Overlay and several special‑standards districts (e.g., Happy Valley Special Standards District) that create place‑based exceptions and additional standards § 17.38.085 § 17.39.010 .
• Overlays typically layer additional permitted uses, design standards, and sometimes incentives (reduced parking, height increases) over the underlying zone; deviations still require adjustments/variances per § 17.24.100 and § 17.25.120 .

(For mapped overlays see the City overlay districts page.)

Building permits & review — the path from idea to permit

1. Determine entitlements needed: check the base zone, any overlay or specific plan, and Division 5 use tables. Minor, ministerial or discretionary classification is set by Class I–VII § 17.06.020 .
2. Ministerial vs discretionary: many ADU, small renovation and ministerial permits are Class I; administrative design review and administrative permits are Class II; conditional use permits, variances and tentative maps are Class IV (Commission/Council review for larger actions) § 17.06.020 § 17.02.050 .
3. Application completeness & environmental review: the Director checks completeness (application checklists), and CEQA screening/initial studies are required where applicable § 17.06.060 and § 17.06.050 .
4. Administrative permit and building permit timing: certain projects require an administrative permit prior to building permit issuance (e.g., new single‑family homes, some additions) § 17.23.100 . Conditions, bonds and covenants may be required before an approved site plan is stamped § 17.06.180 § 17.06.220 .
5. Appeals, effective dates and post‑decision steps: decisions become effective per § 17.06.170 (15 calendar days unless appealed); appeals/certifications of review follow Chapter 17.07 § 17.06.170 .

Practical orientation: small, by‑right projects (e.g., ministerial ADU applications that meet objective standards) proceed through the Director’s Class I checklist and (if complete) can be processed without public hearing; conditional projects will need planning hearings and potentially CEQA review § 17.06.080 .

State housing law in Santa Clarita — ADUs, two‑unit rules, SB9 and other interactions

Summary and code citations (local implementation points):

• Accessory Dwelling Units (ADUs) — Santa Clarita incorporates State ADU rules into Chapter 17.57. ADUs are a ministerial, Class I type of application (Chapter 17.22 references the Class I ADU application) and the City sets objective development standards: typical detached ADU max height 16 ft (with transit/other exceptions to 18 ft), required side/rear setback 4 ft, parking exceptions and other rules (one parking space per new ADU unless within 1/2 mile of transit or other exceptions) § 17.57 (L) § 17.57 (ADU parking & height rules) . The code also addresses multifamily ADUs, allowable sizes, deed restrictions for affordability incentives, and impact‑fee treatment § 17.57 (L) § 17.57 (affordability fee waivers) . See the City ADUs page for local checklists and the State California ADU law for statutory backstop.
• Two‑unit (ministerial duplex) rule (implementation of Government Code 65852.21) — Santa Clarita adopted a local provision allowing two (2) unit residential developments in single‑family zones under objective standards (must allow at least two 800 sq ft units, minimum 4 ft side/rear setbacks or zone setback, one story/16 ft height with specific exceptions, required one enclosed parking space per unit unless transit exemption applies), processed ministerially by the Director § 17.57.025 § 17.57.025 (standards) . The local section also includes affordability and owner‑occupancy covenant requirements where applicable § 17.57.025 .
• SB 9 / urban lot splits and ministerial duplex provisions — Santa Clarita’s two‑unit rules explicitly address urban lot splits and ministerial standards (the two‑unit section references urban lot split coordination and ministerial review process), but explicit SB 9 implementing text (the City’s local ordinance titled to directly reference SB 9) is not apparent in the retrieved extracts. Verify with the Planning Division for the City’s adopted SB 9‑specific procedures and urban lot split (Chapter 16.28 referenced) § 17.57.025 .
• Density bonus, rent control and tenant protections — I did not find an explicit local density‑bonus ordinance or a local rent‑control ordinance in the retrieved Title 17 excerpts. Developers should assume State density‑bonus law still applies (Government Code § 65915) but confirm local administrative practices with the Planning Division (Not found in retrieved materials — verify with the jurisdiction).
• Building code & permits — all construction must comply with the adopted Building Code and California Building Standards (Title 24); ADUs and other dwellings must meet State building standards for dwellings as referenced in the ADU provisions § 17.57 (ADU tie to State building standards) . For technical code compliance see the California Building Standards Code.

If you need, I can extract the exact ADU checklist and ministerial submittal steps from the City’s ADU chapter and the Chapter 17.22 Class I application rules.
