Paso Robles — Overlay Districts

Last reviewed: July 2, 2026

Overview

Overlay zoning districts in Paso Robles are supplemental, geographically‑targeted layers that sit on top of a property's base zoning to add, limit, or tailor uses, development standards, and review procedures for specific places or policy goals. The city’s code lists the set of overlays (HOS, HP, L, MU, PD, SPD, SP, OP) and explains that where a conflict exists the overlay controls. See § 21.36.010 for purpose and applicability.

This reference summarizes what each Paso Robles overlay does in practice, the typical permitted uses, the key standards the code calls out, and where the overlay is applied or how it’s established under the local code. Wherever the code gives a clear numeric standard I cite the controlling §; if the code defers to tables or other chapters I point to those cross‑references.

(First mentions: this page links to the city pages for Paso Robles zoning, development standards, parking, design review, historic preservation, signage, ADUs, and the California Building Standards Code.)

How to read this code

• Overlays supplement an underlying base zone; where overlay and base conflict the overlay prevails (§ 21.36.010).
• Many overlays trigger discretionary review: development plan, conditional use permit, or referral to planning commission/city council as specified in each overlay. When the overlay requires a development plan, see Chapter § 21.16.010 for procedures and required findings.

District-by-district breakdown

HOS — Highway‑Oriented Sign Overlay

• Purpose: regulate height and design of pole signs oriented to highways. § 21.36.020 instructs that HOS is specifically to control highway‑oriented pole signs.
• Typical permitted uses: HOS is not a land‑use overlay; it only modifies sign rules that apply to parcels that face highways. See the sign standards cross‑reference. § 21.36.020 directs applicants to the Highway‑Oriented Signs subsection.
• Key dimensional standards: HOS refers applicants to the sign chapter standard for highway signs (see § 21.52.080(H)). The zoning chapter itself does not restate numeric sign heights; confirm numeric limits in the Signs chapter. § 21.36.020.
• Where it applies: mapped onto parcels that face interstate/highway corridors as shown on the official zoning map; overlay placement is by ordinance. § 21.36.010–.020.

HP — Historic Preservation Overlay

• Purpose: encourage preservation, restoration, and renovation of architecturally significant buildings/neighborhoods. § 21.36.030(A).
• Typical permitted uses: uses are those of the base zone but new construction and significant alterations within HP are subject to architectural review and may be limited consistent with Chapter § 21.62 (Historic Preservation). § 21.36.030(C).
• Key standards: planning commission adopts guidelines considering spacing, lot coverage, setbacks, bulk, height, materials, and block rhythm. Applications for new structures are referred to the planning commission for architectural review. § 21.36.030(C).
• Where it applies: applied to areas with one or more buildings of historic interest; boundaries are determined by the planning commission considering visibility, continuity, and economic impacts. § 21.36.030(B).

L — Lodging Overlay

• Purpose: create locations appropriate for resort/hotel/lodging uses without converting an entire area to commercial zoning; supports the city's visitor‑serving goals. § 21.36.040(A).
• Typical permitted uses: Resort and other hotels, motels/motor hotels, bed and breakfast inns, and similar visitor‑serving uses (subject to review/approval through the development plan process and/or as defined at the time the overlay is applied). § 21.36.040(B).
• Key standards: The overlay is discretionary — the planning commission reviews uses through the development plan process and may add conditions (traffic adequacy and compatibility are explicit considerations). Applications to establish the overlay typically require a site plan and elevations for compatibility. § 21.36.040(A)(2–3); § 21.16.010(C)(3–4).
• Where it applies: established by zone change ordinance on specific properties; may be combined with any base zone. § 21.36.040(A)(2).

MU — Mixed‑Use Overlay

• Purpose: enable multi‑family residential in nonresidential districts, encourage compact, mixed‑use infill and activity throughout the day. § 21.36.050(A).
• Typical permitted uses: In addition to base district uses, MU allows multi‑family dwellings, mixed‑use combining commercial and residential, communal housing, certain care/supportive housing and daycare uses (see § 21.36.050(C)).
• Key dimensional standards: The code provides Table 21.36.050‑1 (Development Standards for Mixed‑Use Overlay) — highlights:
  • Maximum density: 30 dwelling units/acre. Table 21.36.050‑1.
  • Minimum setbacks (residential): Front/street side 10 ft (garages 20 ft); Side 5 ft (1st story)/10 ft (upper stories); Rear 10 ft. Table 21.36.050‑1 and related subsection references.
  • Private open space: 100 sf per unit; Common open space: 100 sf per unit (or 300 sf if only common). Table 21.36.050‑1.
  • Building height: underlying zone height applies. Table 21.36.050‑1.
  • Parking: see Chapter § 21.48 (Parking and Loading Regulations) — mixed‑use projects must meet parking or any overlay‑specific modifications. Table 21.36.050‑1 cross‑ref.
• Where it applies: mapped to specific parcels by ordinance and can be applied in combination with any base zone to enable residential uses. § 21.36.050(B–C).

PD — Planned Development Overlay

• Purpose: identify properties where a development plan is required (even where a development would not otherwise trigger one). § 21.36.060(A).
• Typical permitted uses: uses are those of the base zone, but every project in a PD overlay requires a development plan approval under Chapter § 21.16; the PD overlay can be used to tailor standards to an individual property. § 21.36.060(B–C).
• Key standards: PD projects must comply with the Title unless an approved site plan or development plan modification authorizes changes (see § 21.17.020 and § 21.16.020). The PD overlay emphasizes a development plan hearing before the planning commission. § 21.36.060(C).
• Where it applies: applied by ordinance to specific parcels and functions in combination with base zoning. § 21.36.060.

SPD — Special Planned Development Overlay (and established SPDs A–J)

• Purpose: provide flexibility and negotiated standards for specific properties; SPDs are written into the code as parcel‑specific overlays with tailored permitted uses, conditions, and modifications to base standards. § 21.36.070 and Chapter 21.11 explain the SPD overlay purpose and procedures.
• Typical permitted uses and conditions: each SPD (A, B, C, F, G, H, I, J, etc.) includes site‑specific lists and requirements. Examples from the code (each established by ordinance and shown on the official zoning map):
  • SPD A (21.04.020): requires a conditional use permit for any use on the parcel at 2501 Theater Drive. § 21.04.020.
  • SPD B (21.04.030): six parcels mid‑block near Mesa Road require conditional use permits and access/quitclaim conditions before commercial use. § 21.04.030.
  • SPD C (21.04.040): Theater Drive area C‑2/PD properties conditioned to require conditional use permits to prevent adverse downtown impacts. § 21.04.040.
  • SPD F (21.04.070): C‑3/PD properties east of Golden Hill Road require masonry walls and landscape buffers where abutting residential and require CUPs for uses to reduce noise/visual impacts. § 21.04.070.
  • SPD G (21.04.080): R‑A properties near Airport Road limit future parcelization (20‑acre minimum) and allow two primary dwellings on >=20‑acre parcels. § 21.04.080(A–B).
  • SPD H (21.04.090): 1450 Golden Hill Road is conditioned to limit uses to senior retirement/residential care via CUP. § 21.04.090.
  • SPD I (21.04.100): a 21.4‑acre site limited to agriculture/recreation/winery/hotel uses (with use chart for permitted vs CUP uses). § 21.04.100.
  • SPD J (21.04.110): Paso Robles Gateway project overlay with area‑specific limits and design requirements; development plan required. § 21.04.110.
• Key standards and modification authority: Chapter § 21.11.050 lists the types of standards an SPD may modify (lot sizes, setbacks, grading/hillside standards, sign standards, parking, types/intensity of uses, building heights for projects, and public improvement dimensions). § 21.11.050.
• Where it applies: each SPD is mapped by ordinance and recorded on the official zoning map; see Chapter 21.04 for the established SPDs and the ordinance citations that created them. § 21.04.010 et seq.

SP — Specific Plan Overlay

• Purpose: a specific plan (SP) overlay is intended to implement detailed land use/regulating plans and once adopted the specific plan governs all use and development within its bounds; where the specific plan is silent the zoning title applies. § 21.36.080; § 21.14.010.
• Typical permitted uses and standards: regulated by each specific plan document (Borkey, Uptown Town Center, Olsen‑South Chandler, Beechwood, etc.). The specific plan can supersede base zoning and overlays inside its map area. § 21.14.010(B).
• Where it applies: mapped via ordinance and identified in Chapter 21.05 / 21.13 entries for adopted specific plans. § 21.36.080(D).

Checklist — What an applicant must satisfy for an overlay project

• Verify overlay(s) mapped on the parcel on the official zoning map (city zoning map) — overlay controls where conflict exists. § 21.36.010.
• Determine whether the overlay requires a development plan, conditional use permit, or planning‑commission/city‑council approval (e.g., PD, SPD, L, HP). See the overlay’s § (examples: § 21.36.060, § 21.11.020, § 21.36.040, § 21.36.030).
• Prepare submittal materials required by Chapter § 21.16 (development plan) or Chapter § 21.19 (CUP), including site plans, elevations, landscape plans — SPDs often require more detailed master plans. § 21.11.020; § 21.16.010.
• For MU projects, check Table 21.36.050‑1 for setbacks, open space, density and design standards; coordinate parking per Chapter § 21.48.
• For HP overlays, assemble materials addressing compatibility with the historic guidelines and expect referral to planning commission for architectural review (§ 21.36.030(C)).
• If proposing modifications via an SPD/PD/site‑plan modification, prepare justifications tied to the findings in § 21.11.050 or § 21.17.020 (superior project, no feasible alternatives, no detriment).

Risks & Ambiguities

Plain‑English Summary

Paso Robles overlays (HOS, HP, L, MU, PD, SPD, SP, OP) are extra rules placed on top of a property's base zoning to handle special areas or projects — they can add allowed uses, require a development plan or CUP, or change standards like setbacks, parking, or signs; the overlay text and any parcel‑specific SPD is the controlling requirement so always check the specific overlay § and the official zoning map first (Verify with the jurisdiction). § 21.36.010; Ch. 21.04; § 21.11.050.

Information Gaps

• Exact numeric sign heights and areas for HOS are referenced but not stated in the overlay chapter; the code refers to the Signs chapter (the numeric sign standards were not included in the retrieved excerpts). Not found in retrieved materials — confirm in § 21.52.080(H).
• Parcel‑level overlay boundaries and the official zoning map itself are not included in the retrieved text — map confirmation requires the city’s zoning map. Not found in retrieved materials — Verify with the jurisdiction. § 21.06.010.
• Some SPD ordinance text includes specific numeric limits for individual sites (e.g., hotel room caps, wall heights, landscape widths) — where numbers exist they are in each SPD section; if you need parcel‑specific figures consult the exact SPD subsection in Chapter 21.04.
