Pacifica — Overlay Districts

Q: Can a cannabis retail store open anywhere in Pacifica if the base zone allows retail?

No. Cannabis retail is governed by the Cannabis Operation Overlay (CO) : no cannabis uses are permitted by right in the CO; cannabis uses are allowed only as conditional uses subject to a cannabis activity permit , and the City caps cannabis retail operations citywide at six (6) with additional per‑overlay limits. See §§ 9‑4.1751–9‑4.1756 and Table 9‑4.1755(a).

Q: If my lot is in the MFH‑PY overlay, do I measure setbacks from the polygon or the property line?

Setbacks are measured from the property lines , not the polygon boundaries; however, lot coverage and other polygon allowances are calculated based on the polygon area, and lot coverage can be proposed up to 100% of the polygon area (less required setbacks). See § 9‑4.6703(a)(ii–iii) .

Q: Is the Lot Size Overlay District B‑ fully described in the retrieved ordinance excerpts?

No — the listing of the Lot Size Overlay District (B‑) appears in the zoning district list, but the detailed provisions for that overlay were not found in the retrieved materials . For the B‑ overlay you must verify the actual article or contact Planning. § 9‑4.302 shows the district list.

Overview

Overlay and combining districts in the City of Pacifica modify or supplement the rules of the underlying base zones to address special resources, sensitive areas, or targeted land‑use programs. The Pacifica Municipal Code establishes several overlay/combining districts — most prominently the Cannabis Operation Overlay (CO), the Coastal Zone Combining District (CZ), Special Area Combining Districts (SA), and the Multi‑Family Housing Combining District (MFH‑PY) — each with its own purpose, map boundaries, and controlling standards. Confirm a parcel’s overlay status on the City zoning map before planning a project; see the City’s zoning overview for context. Pacifica Zoning

How to read this page

This page sticks strictly to what the Pacifica zoning/planning ordinance text says about overlay/combining districts. Every requirement below is grounded in the code and cites the controlling section (§) and the retrieved ordinance file.

District-by-district breakdown

Note: Because overlay rules frequently defer to the underlying zone, applicants must check both the overlay article and the underlying base‑zone standards (setbacks, height, parking). See the City’s development standards page when the ordinance references underlying standards.

Cannabis Operation Overlay District (CO)

What it is: The Cannabis Operation Overlay (CO) is a set of five geographically‑defined overlay districts created to control the location and number of cannabis businesses in specific areas of Pacifica. The CO is described in § 9-4.1751–§ 9-4.1756.
Overlay names / geography: CO-F (Fairmont), CO‑LM (Linda Mar), CO‑PP (Park Pacifica), CO‑RB (Rockaway Beach), and CO‑SP (Sharp Park). § 9-4.1753 names these districts.
Purpose: Retain local control over the location and number of cannabis businesses to protect public health, safety and welfare. § 9-4.1752.
Allowed uses / permit path:
- Permitted uses: None. All cannabis operations in these overlays require discretionary authorization; conditional uses are allowed only by obtaining a cannabis activity permit and complying with Article 48 and the CO article. § 9-4.1754.
- Numeric cap: The Citywide cap is a maximum of six (6) cannabis retail operations; the CO article further allocates maximum numbers by overlay (for example, CO‑F: 2, CO‑LM: 2, CO‑RB: 3, etc.). See § 9-4.1755 and Table 9-4.1755(a).
Dimensional / development standards: The CO article defers to the development standards of the underlying zoning district or districts except where the CO specifically addresses a subject. § 9-4.1756.
Practical guidance: If your parcel is inside a CO polygon you must (a) obtain a cannabis activity permit under Article 48, (b) ensure the Citywide and overlay numeric limits have not been reached, and (c) comply with the underlying zone standards for setbacks, parking, and building form. §§ 9-4.1751–9-4.1756.

Coastal Zone Combining District (CZ)

What it is: The Coastal Zone Combining District (CZ) is a combining/overlay district that applies to the Pacifica Coastal Zone and supplements the underlying zones with policies implementing the Coastal Act. § 9-4.4300–§ 9-4.4302.
Purpose and effect:
- Purpose includes protecting coastal resources, maximizing public access, and giving priority to coastal‑dependent uses. § 9-4.4300.
- Applicability: CZ supplements the underlying basic zones and prevails in the event of a conflict with the underlying zone. § 9-4.4301.
Permits & supplemental requirements: The CZ articles reference additional coastal development regulations and special area combining districts (Articles 44 and 45) and therefore frequently trigger additional review (coastal development permit or conformance to local coastal plan provisions). Verify coastal permit needs; the ordinance materials reference these other articles. § 9-4.4300–4302.
Practical guidance: If your site is within the CZ, anticipate Coastal Act–aligned findings, public access/reservation of view corridors, and that the CZ rules will control where they conflict with base zone rules. See the City’s land use pages for interplay between the Local Coastal Plan and zoning.

Special Area Combining Districts (SA) — selected examples

What they are: Special Area Combining Districts (SA) are site‑specific overlays created for unique places along Pacifica’s coast and other sensitive areas. The ordinance contains multiple SA districts (SA‑1, SA‑2, SA‑3, SA‑4, etc.). See the SA articles; examples below are pulled from the retrieved material.
SA‑3 Headlands (Headlands/San Pedro Beach)
- Applicability: Applies to the property commonly known as the Headlands. § 9-4.4512.
- Uses: Conditionally permitted uses include lodging, eating establishments, and public trails/vista areas. § 9-4.4512.
- Development controls: Public shoreline access, bicycle parking, emergency access, and a prohibition on structures on designated prominent ridgelines unless no other buildable area exists. § 9-4.4513.
SA‑4 Pacifica State Beach
- Purpose: Recognizes beach‑specific environmental constraints (sensitive species, wetlands, parking shortages, panoramic views) and tailors regulation accordingly. § 9-4.4514.
Practical guidance: SA districts are parcel‑specific; permitted uses and conditions can be very different than the base zone. Check the SA article that applies to your parcel to identify required public access, parking, and programmatic requirements.

Multi‑Family Housing Combining District (MFH‑PY)

What it is: MFH‑PY is a combining/overlay district that identifies specific parcels (shown in a table) where modified zoning provisions apply to enable housing development from the City’s Housing Element sites inventory. See § 9-4.6702–9-4.6703.
Geography: Table 9-4.6702(a) lists the APNs and site addresses included in the overlay (example sites include Oddstad Boulevard, 401 Paloma Avenue, 1450 Terra Nova Boulevard, and others). § 9-4.6702.
Key rules / deviations from underlying zone:
- Within specific polygons of a site the overlay allows modified zoning provisions regardless of the parcel’s base designation. § 9-4.6703(a)(i).
- Setbacks are measured from property lines, not polygon boundaries. § 9-4.6703(a)(ii).
- Lot coverage for a polygon is calculated on the polygon area; projects may propose lot coverage up to 100% of the polygon area (less required setbacks). § 9-4.6703(a)(iii).
Practical guidance: If a parcel is inside the MFH‑PY polygonal area, expect altered site‑planning metrics (lot coverage and usable buildable areas) and the need to conform to the combining district’s additional requirements rather than (or in addition to) the underlying zone. Verify polygon boundaries on the zoning map. § 9-4.6702–6703.

Other overlay / combining mentions in the code

The code’s zoning district list shows several combining or special districts including Lot Size Overlay District B‑ and Single‑Family Residential Hillside District (R‑1‑H); these are named in the zoning district list and map provisions but detailed provisions for the Lot Size Overlay (B‑) were not located in the retrieved excerpts. Confirm specifics with the City (verify with the jurisdiction). § 9-4.302 and district list.

Quick reference table — decision-relevant standards and uses

Overlay / Combining District	Most decision‑relevant rule(s)	Code Reference
Cannabis Operation Overlay (CO) — CO‑F, CO‑LM, CO‑PP, CO‑RB, CO‑SP	No permitted cannabis uses by right; cannabis uses only as conditional uses with a cannabis activity permit; Citywide cap: 6 retail operations; overlay limits by district shown in Table 9‑4.1755(a).	§ 9‑4.1751–9‑4.1756
Coastal Zone Combining District (CZ)	Supplements underlying zones for coastal areas; CZ prevails over underlying zone where they conflict; Coastal Act priorities apply.	§ 9‑4.4300–9‑4.4302
Special Area (SA‑3 Headlands, SA‑4 State Beach)	SA‑3: lodging/eating/public trails conditionally permitted; public shoreline access and no structures on designated ridgelines; SA‑4: beach/environmental constraints.	§ 9‑4.4512–9‑4.4514
MFH‑PY Combining District	Polygonal areas allow modified zoning; setbacks measured from property lines; lot coverage may be up to 100% of the polygon (less setbacks).	§ 9‑4.6702–9‑4.6703
Zoning map / district identification	Overlay status and boundaries are on the City zoning map (designations are part of the code and map). Verify on the map.	§ 9‑4.302

Checklist

Verify overlay status and polygon boundaries on the City zoning map (§ 9‑4.302).
If inside a CO, confirm whether the overlay still has available cannabis retail slots and plan to apply for a cannabis activity permit; follow Article 48 plus the CO article §§ 9‑4.1754–1755.
For CZ parcels, determine whether a coastal development permit or Local Coastal Plan findings will be required; CZ provisions supplement and prevail where they conflict. § 9‑4.4301.
For SA parcels, review the exact SA article that covers the site (permitted uses and public access/shoreline conditions). § 9‑4.4512–4514.
For MFH‑PY parcels, confirm polygon vs. parcel limits, calculate lot coverage on the polygon area, and check setback measurement rules. § 9‑4.6703.
Ensure compliance with underlying zone standards for setbacks, parking, and height unless the overlay expressly modifies them; consult the City’s development standards and parking pages where the code refers to underlying standards.
Confirm whether design review, historic review, or other discretionary reviews are triggered; consult the City’s design review and historic preservation resources.
Obtain required state technical compliance (for construction or occupancy) with the California Building Standards Code and applicable fire/building inspections as required by the City.

Risks & Ambiguities

Issue	Why it matters	What to verify
Overlay polygon vs. whole parcel (MFH‑PY)	MFH‑PY modifies zoning only within a polygon — building area, lot coverage and allowances apply to the polygon, not necessarily the whole lot. Misreading can produce non‑compliant plans.	Confirm polygon boundaries on the zoning map and the combining district table; review § 9‑4.6702–6703.
Citywide and overlay numeric caps (CO)	There are hard limits on number of cannabis retail operations citywide and per overlay. Exceeding the cap prevents permit approval.	Verify current counts and the applicable overlay allocation in § 9‑4.1755 (Table 9‑4.1755(a)).
Which rules “prevail” when overlay and base conflict	Different overlays state differing precedence rules (CO notes its provisions prevail where addressed; CZ explicitly prevails). Misinterpreting precedence can lead to incorrect entitlement strategy.	See § 9‑4.1751 (CO scope) and § 9‑4.4301 (CZ applicability and precedence).
Missing overlay detailed standards (Lot Size Overlay B‑)	Some overlay names appear in the district list, but their detailed article text was not found in the retrieved excerpts.	Not found in retrieved materials — contact Planning or check the full PMC for the specific overlay article. Verify with the jurisdiction.
Coastal review / Local Coastal Plan interplay	CZ and SA districts reference Coastal Act and Local Coastal Plan requirements; project scope could trigger Coastal Act findings or coastal permits beyond ordinary local review.	Confirm coastal permit triggers and any LCP‑required findings; see § 9‑4.4300 and related Coastal articles.

Plain‑English Summary

Pacifica’s overlays (for example the Cannabis Operation Overlay (CO), Coastal Zone (CZ), special area SA districts, and the MFH‑PY housing overlay) place additional, often parcel‑specific rules on top of the base zoning. Some overlays ban or limit specific uses (CO for cannabis), others require public access or protect coastal resources (CZ and SA), and some change site development rules inside mapped polygons (MFH‑PY). Always check the City zoning map and the specific overlay article — the overlay text and its cited code sections control what you can do. Verify with the jurisdiction for parcel‑specific interpretations.

Frequently asked questions

What is an overlay district in Pacifica and how do I know if my property is in one?

An overlay (or combining) district in Pacifica is a set of rules that is superimposed on top of the base zoning for specific areas (e.g., coastal areas, special plan sites, or cannabis overlay neighborhoods). Check the City zoning map and the district list — overlay boundaries are part of the zoning map and adopted in the code under § 9‑4.302. Verify the parcel on the map and then read the overlay’s article (e.g., CO, CZ, SA, MFH‑PY) for the exact standards.

Can a cannabis retail store open anywhere in Pacifica if the base zone allows retail?

No. Cannabis retail is governed by the Cannabis Operation Overlay (CO): no cannabis uses are permitted by right in the CO; cannabis uses are allowed only as conditional uses subject to a cannabis activity permit, and the City caps cannabis retail operations citywide at six (6) with additional per‑overlay limits. See §§ 9‑4.1751–9‑4.1756 and Table 9‑4.1755(a).

Does the Coastal Zone Combining District (CZ) change setback or parking requirements?

The CZ supplements the underlying zone and applies coastal policies; where CZ provisions conflict with the underlying zone the CZ prevails. The CZ article sets coastal priorities (public access, resource protection) and may require different findings or conditions, but many dimensional standards still come from the underlying zone unless the CZ explicitly modifies them. See § 9‑4.4300–4302.

If my lot is in the MFH‑PY overlay, do I measure setbacks from the polygon or the property line?

Setbacks are measured from the property lines, not the polygon boundaries; however, lot coverage and other polygon allowances are calculated based on the polygon area, and lot coverage can be proposed up to 100% of the polygon area (less required setbacks). See § 9‑4.6703(a)(ii–iii).

Do overlays automatically change parking requirements?

Not automatically. Many overlays defer to the underlying zone for parking, setbacks, and height unless the overlay specifically modifies them (for example MFH‑PY modifies lot coverage). Always check the overlay article and then check the City’s parking standards; the CO article explicitly says development standards remain those of the underlying zone unless addressed in the CO. § 9‑4.1756.

Can an overlay override the base zoning?

Yes — in Pacifica some overlay articles explicitly state that their provisions prevail where they conflict with the underlying zoning (for example CZ and the CO article both explain their scope and precedence). Check § 9‑4.1751 (CO scope) and § 9‑4.4301 (CZ applicability and precedence).

If my project is in the Coastal Zone, will I need a Coastal Development Permit?

Possibly. The CZ article is written to implement Coastal Act priorities and references the Local Coastal Plan and other Coastal articles; projects in the coastal zone commonly trigger Coastal Act or LCP review. The overlay text indicates CZ provisions supplement the underlying zones — confirm whether a coastal development permit is required for your specific project with Planning. §§ 9‑4.4300–4302.

The overlay text refers to “underlying zoning standards.” Where do I find those?

Underlying zoning regulations (setbacks, height, permitted uses, parking) are in the base district articles and in the City’s development standards; overlays will explicitly say when they defer to the underlying zone (for example § 9‑4.1756 for CO). You should consult the underlying base district article plus the City’s development standards and parking rules when preparing plans.

Is the Lot Size Overlay District B‑ fully described in the retrieved ordinance excerpts?

No — the listing of the Lot Size Overlay District (B‑) appears in the zoning district list, but the detailed provisions for that overlay were not found in the retrieved materials. For the B‑ overlay you must verify the actual article or contact Planning. § 9‑4.302 shows the district list.
