Santa Clarita — Overlay Districts

Last reviewed: July 2, 2026

Overview

Santa Clarita’s overlay zones are special zoning classifications layered on top of the base zoning map to add location-specific requirements or allowances (for example for ridgelines, billboards, homeless shelters, job-creation sites, vehicle clusters, and senior mobilehome parks). The overlays do not replace the underlying base zone; they modify or add permitted uses, design standards, or approval requirements that apply in addition to the base zone standards. For base zoning policy and maps see Santa Clarita Zoning and for how overlays interact with routine setbacks and development rules see Santa Clarita Development Standards.

Below are the City of Santa Clarita overlay zones codified in Title 17 that an applicant or homeowner is most likely to encounter. Each district summary gives the ordinance purpose, the typical permitted/conditional uses called out in the overlay, the principal development or procedural controls, and where the overlay applies or how its boundary is established.

BR — Billboard Relocation Overlay Zone

• Purpose: Preserve opportunities to reduce and relocate legally established billboards while reducing overall billboard numbers.
• Typical permitted uses: All uses of the underlying commercial/industrial zone remain, except that off‑site signs (billboards) are permitted only through a billboard reduction and relocation agreement or a development agreement consistent with the BR rules.
• Key standards/procedures: Applies within 300 ft of the Interstate‑5 and State Route‑14 centerlines as shown on the adopted zoning map; relocated billboards must also comply with the California Outdoor Advertising Act where within 660 ft of a State highway; separation rules for digital billboards (example: 2,500 ft minimum separation on same side of freeway) are included. § 17.38.005.

HS — Homeless Shelter Overlay Zone

• Purpose: Implement State requirements (SB 2) by identifying where homeless shelters are permitted in the City.
• Typical permitted uses: All underlying zone uses continue except the overlay explicitly permits Homeless Shelters where the overlay applies (symbol “P”). Additional development standards for shelters reference § 17.66.070 (Homeless Shelters).
• Key standards/procedures: Applies only in areas shown on the adopted map on file in the Planning Division; shelter projects must meet the standards in § 17.66.070 and any deviations require an adjustment or variance per § 17.24.100 and § 17.25.120. § 17.38.010.

JC — Jobs Creation Overlay Zone (JCOZ)

• Purpose: Encourage development of targeted industries (aerospace, biomedical, entertainment, technology, and other Director‑approved industries), improve the jobs/housing balance, and incentivize office/industrial projects in defined areas.
• Typical permitted uses: Applies only to office and industrial buildings (other building types like hotels, hospitals, residential, and vertical mixed‑use are not eligible).
• Key standards/procedures: Office projects must meet a minimum height of three (3) stories; industrial projects must have height > 35 ft; developments must also meet the underlying zone rules plus any JC design standards. § 17.38.015.

RP — Ridgeline Preservation Overlay Zone

• Purpose: Protect the visual integrity of significant ridgelines that are highly visible to the community.
• Typical permitted uses: All uses allowed by the underlying zone remain but require a ridgeline alteration permit for engineered slopes, structures, streets, utilities, or other manmade features within the overlay.
• Key standards/procedures: The RP overlay protects land within 100 ft vertical and 100 ft horizontal distance of the mapped ridgeline; the Director may exempt developments on substantially disturbed or urbanized sites at their discretion; any deviation from RP standards requires an adjustment or variance (§ 17.24.100, § 17.25.120). § 17.38.070.

PD — Planned Development Overlay Zone

• Purpose: Provide additional discretion for redevelopment or previously vacant parcels identified on the City’s zoning map; specifically triggers review for significant projects.
• Typical permitted uses: Underlying uses apply, but new development or redevelopment exceeding 50% of existing structure valuation is subject to approval of a Conditional Use Permit (CUP).
• Key standards/procedures: All projects exceeding the 50% valuation threshold (as determined by the Building Official) require CUP approval in addition to the underlying zone rules. § 17.38.060.

MU — Mixed Use Overlay Zone

• Purpose: Encourage mixed‑use development that responds to context and the City’s Community Character and Design Guidelines.
• Typical permitted uses: Mixed use projects combining residential and commercial; the overlay prescribes open space minimums, architecture expectations, and design review.
• Key standards/procedures: Mixed use projects must provide 200 sq ft per residential unit minimum open space (can be communal), follow Community Character and Design Guidelines, and are subject to City design review processes for architecture and site design. Deviations require adjustment or variance procedures. § 17.38.0xx (Mixed Use Overlay provisions summarized in Chapter 17.38; see the MU subsections in the code).

VDS — Vehicle Dealer Sales Overlay Zone

• Purpose: Concentrate and regulate vehicle dealer sales and services in specific areas to reduce proliferation of auto‑related uses elsewhere.
• Typical permitted uses: Vehicle sales and associated services are permitted or conditionally allowed (a table in the VDS lists specific vehicle sales/services and whether they are P or M). Minor use permits are required for some repair/painting activities; body repair and painting that is incidental to a new-vehicle dealership is treated differently.
• Key standards/procedures: General development requirements follow the underlying zone; special VDS rules include no outdoor display/storage of vehicle parts, operations conducted within enclosed buildings, masonry fencing (no chain link), and storage rules for wrecked vehicles (e.g., enclosed or impound). Variances/adjustments required for deviations (§ 17.24.100, § 17.25.120). § 17.38.090.

VS — Vehicle Services Overlay Zone

• Purpose: Allow and control vehicle repair and service uses while protecting surrounding neighborhoods and requiring operational safeguards.
• Typical permitted uses: Vehicle repair/painting and related services, often with permits or minor use requirements depending on the use and context.
• Key standards/procedures: Requires enclosed operations for many activities; repair hours restricted (for example, 7:00 a.m.–10:00 p.m. Mon–Fri and 8:00 a.m.–7:00 p.m. Sat/Sun for some repair activities); solid masonry fences required (no chain link); on‑site parking and circulation must be provided. § 17.38.100.

SMHP — Senior Mobilehome Park Overlay Zone

• Purpose: Preserve existing senior mobilehome parks and limit conversion to all‑ages parks to maintain senior housing supply.
• Typical permitted uses/requirement: Parks designated as Senior Mobilehome Park must maintain at least 80% occupancy by persons age 55+; new leases must be issued only to seniors except when park occupancy reaches 90% senior occupancy (remaining spaces may then be rented to non‑seniors). Parks must label themselves as senior parks in leases and signage.
• Key standards/procedures: The ordinance lists the designated parks and APNs that are subject to the SMHP overlay; the City conducts biennial verification and requires notification when new leases are signed. Violations are enforceable by Municipal Code enforcement. § 17.38.085.

Practical guidance & comparisons

• Overlay + underlying zone: Always read the overlay’s text together with the underlying base zone standards (density, setbacks, height, parking). Overlays generally state “All uses of the underlying zone shall follow the requirements and restrictions associated with that zone,” and then add overlay‑specific conditions (for example RP, VDS, HS) — so design, parking, and setback compliance still matters. For parking specifics consult Santa Clarita Parking. § 17.38.x (overlay introductions) and specific overlay subsections.

• Design and reviews: Many overlays require additional review or special permits (ridgeline alteration permit, minor use permits, conditional use permits). Projects in overlays are frequently subject to the City’s Community Character and Design Guidelines and City design review procedures; see Santa Clarita Design Review for the review process referenced in overlay provisions. For deviations, the overlay directs applicants to the Adjustment and Variance processes (§ 17.24.100 and § 17.25.120).

• Signs and billboards: Billboard relocations are tightly regulated in the BR overlay; relocated signs must comply with both local conditions and the California Outdoor Advertising Act in some locations. Consult the Santa Clarita Signage rules in conjunction with § 17.38.005.

• Sensitive numeric thresholds to watch for: 50% redevelopment valuation (PD), 80% / 90% senior occupancy thresholds (SMHP), 3 stories / 35 ft minimum height for JC, and 100 ft vertical / 100 ft horizontal ridgeline buffer (RP). Always confirm how the City measures valuation, height, or slope in a specific application—these cross‑refer to other Title 17 subsections and Building Official determinations. § 17.38.060, § 17.38.085, § 17.38.015, § 17.38.070.

• Sites and maps: Most overlays state that applicability is determined by an adopted overlay map “on file in the Planning Division.” If you are evaluating a parcel, verify the overlay boundary with the Planning Division—the ordinance repeatedly points to the official map on file rather than listing every parcel in the text (exception: SMHP lists designated parks and APNs). § 17.38.005, § 17.38.070, § 17.38.085.

• Interaction with building code and ADUs: Overlays add land‑use and locational controls; they do not replace building construction standards in the California Building Standards Code (Title 24). For building code compliance and ADU‑specific statewide rules, consult the California Building Standards Code and Santa Clarita ADUs pages. Where an overlay limits a use (for instance, JC excluding residential building types), ADU permissibility may still be governed by state ADU law and local ADU rules — verify with the jurisdiction.

Checklist — what an applicant must satisfy (typical)

• Confirm whether the parcel is inside an overlay by checking the City’s official overlay map on file with the Planning Division (verify for BR, HS, RP, etc.). § 17.38.005, § 17.38.070.
• Confirm underlying base zone standards (setbacks, lot coverage, FAR, parking) and reconcile overlay additions. § 17.38.x (overlay preambles).
• Determine whether overlay requires a special permit (ridgeline alteration permit, minor use permit, conditional use permit) and prepare required studies (topographic mapping for RP; traffic study for certain PCSSD locations; lease/occupancy documentation for SMHP). § 17.38.070, § 17.38.085.
• Address overlay‑specific operational controls (hours, fencing, enclosures for VS/VDS; masonry walls; billboard agreements for BR). § 17.38.100, § 17.38.090, § 17.38.005.
• If seeking deviations, prepare findings for an Adjustment (§ 17.24.100) or Variance (§ 17.25.120) as overlays explicitly reference those processes.
• For projects invoking design flexibility or required design review, align plans with the City’s Community Character and Design Guidelines and be ready for Design Review. See Santa Clarita Design Review.

Risks & Ambiguities

Plain‑English summary

Santa Clarita’s overlay zones layer extra, location‑specific rules on top of base zoning: they allow or restrict specific uses (billboards, shelters, vehicle dealers, senior parks), impose design or operational controls (ridgeline protections, masonry walls, occupancy percentages), and usually refer you to the City’s official overlay maps in the Planning Division; always check both the overlay text (Title 17) and the map for parcel‑level applicability and the special permits required. § 17.38.005–§ 17.38.100, § 17.38.085.
