Ferndale — Overlay Districts
Overlay Districts under the Ferndale local zoning and planning code, with the controlling citations.
Last reviewed: July 6, 2026
Overview
Ferndale uses “combining” zones (overlays) to layer special rules on top of the underlying base zoning. The City’s Zoning Ordinance 02‑02 establishes these overlays in Article 4 and regulates them in Article 6, with boundaries shown on the official zoning map (§ 4.02–§ 4.04 ). Where a combining zone applies, it either narrows allowed uses, adds protections (like streamside buffers), or substitutes different dimensional standards for the base district.
In Ferndale, a combining zone overlays the base zone; you must meet both the base-zone rules and any overlay-specific rules that apply to your parcel (§ 4.02–§ 4.04; see Article 6 for each overlay’s standards ).
Use this page together with the Ferndale Zoning map/classifications and the city’s Ferndale Development Standards. When an overlay triggers extra review or standards (for example, design control), coordinate early with Ferndale Design Review and check applicable Ferndale Parking rules if the overlay references them.
The Combining (Overlay) Zones at a Glance
Ferndale’s overlays are established in § 4.02: Agriculture (-A), Special Building Site (-B), Recreation (-X), Design Control (-D), Qualified Combining (-Q), Housing Combining (-H), and Streamside Protection (-SPA) (§ 4.02 ).
Agriculture Combining (‑A)
- Purpose and where it applies: Adds agricultural and livestock standards to parcels mapped with “‑A” in addition to their base zoning; see zoning map for exact boundaries (§ 4.03–§ 4.04 ).
- Typical permitted uses:
- General agriculture and livestock, with numeric limits for certain animal categories (examples: up to 5 sheep/goats or similar-size animals per ½ acre; small livestock such as rabbits or chickens up to 200 animals per ½ acre) (§ 6.02.1–§ 6.02.3 ).
- Small and large employee housing associated with agriculture (§ 6.02.1.e–f ).
- Uses with a Use Permit:
- Animal hospitals/kennels; on‑premises retail sale of agricultural products; keeping of animals beyond listed categories (§ 6.02.2 ).
- Key dimensional/operational standards:
- Barns, corrals, pens at least 50 ft from any residence and 20 ft from any lot line; no large‑livestock butchering on premises except for noncommercial use (§ 6.02.3.a–b ).
Special Building Site Combining (‑B)
- Purpose and where it applies: Substitutes lot area and yard requirements for those in the base zone where sound planning calls for modified parcels/yards; mapped as “‑B” plus a sub‑designation (B‑1 through B‑6) (§ 6.03 ).
- Typical effect: Replaces front, side, rear yards and minimum building site area with the values set by the B‑subzone (see table below).
- Key dimensional standards (apply in place of base‑zone yards/site area) (§ 6.03 ):
- B‑1: 8,000 sq ft site; 25 ft front; sides at 10% of lot width (min 8 ft); 10 ft rear
- B‑2: 10,000 sq ft; 25 ft front; sides at 10% (min 10 ft); 10 ft rear
- B‑3: 20,000 sq ft; 30 ft front; sides at 10% (min 15 ft); 15 ft rear
- B‑4: 1 acre; 30 ft front; sides at 10% (min 20 ft); 20 ft rear
- B‑5: As specified on zoning map, but never less than B‑4
- B‑6: Site area per final subdivision map; yards not less than B‑4 unless map states otherwise
Recreation Combining (‑X)
- Purpose and where it applies: Adds recreational uses to compatible base zones without harming adjacent uses; mapped “‑X” (§ 6.04 ).
- Principal permitted uses:
- Public/private noncommercial recreation; general agriculture/roadside stands; dwellings/offices incidental to permitted uses; trailer camps/mobile home parks; public campgrounds (§ 6.04.1 ).
- Uses with a Use Permit:
- Commercial recreation; compatible commercial uses the Planning Commission finds won’t impair area uses (§ 6.04.2 ).
- Key dimensional standards:
- Minimum lot area 5 acres; width 300 ft; front/side/rear yards 50 ft; max height 30 ft (§ 6.04.3 ).
Design Control Combining (‑D)
- Purpose and where it applies: Protects the historic character and visual quality of mapped areas by regulating the appearance of buildings and signs (§ 6.05; amended by Ord. 2024‑01 ).
- What it requires:
- A Design Review Permit is required before erecting, altering, or remodeling any sign, structure, or building in a way that changes outward appearance, unless exempted by the city’s sign ordinance (§ 6.05.2 ). See Ferndale Signage.
- Planning Commission conducts conceptual and final design review; final review results in a decision and may impose conditions (§ 6.05.4.a–b ).
- Timing: If a building permit is required and not obtained within 6 months of Design Review approval, the Design Review Permit automatically expires; staff may grant one 6‑month extension if requested before expiration (§ 6.05, timing/extension rules ).
- Relationship to historic character: Purposes include ensuring architecture, materials, colors, and signs are visually harmonious with surrounding development and the area’s historic appearance (§ 6.05.1.a–d ). See also Ferndale Historic Preservation.
Qualified Combining (‑Q)
- Purpose and where it applies: Used in commercial zones where residential use predominates, to protect residential peace/health/welfare by limiting which commercial uses can occur (§ 6.06 ).
- Principal permitted uses:
- Single‑family dwellings; boarding of not more than two persons not employed on the premises; small employee housing (§ 6.06.1 ).
- Uses with a Use Permit:
- Two‑family dwellings; small multi‑family (not more than four families); offices; commercial instruction; private institutions; B&Bs/boarding houses; small‑animal clinics; mortuaries; plant nurseries; limited in‑building retail/services like antique shops, salons, bookstores, florists, small restaurants, small‑scale retail, studios, tailoring, and wholesale food prep/catering (§ 6.06.2.a–k ).
- Other uses allowed if also permitted in the base zone and found similar/compatible by the Planning Commission (§ 6.06.2.l ).
- Key standards and cross‑references:
- Dimensions/height follow the base zone (§ 6.06.3.a ).
- Off‑street parking/loading must meet § 7.16; coordinate early with Ferndale Parking (§ 6.06.3.b ).
- Existing land/building uses that conformed to the base zone before the ‑Q overlay are allowed to continue and do not become nonconforming; expansions may be allowed via Use Permit if consistent with ‑Q’s purpose (§ 6.06.3.c; see also Ferndale Nonconforming Uses ).
Housing Combining (‑H)
- Purpose and where it applies: Site‑specific overlay intended to cover the existing duplex units on a portion of the Ferndale Housing Project area along Fairview Drive and Trident Lane; principally permits those existing duplexes (§ 6.07 ).
- Practical note: The text is narrowly focused on the existing duplex area; any new or altered use should be confirmed against mapping and the overlay’s stated purpose. Verify with the jurisdiction.
Streamside Protection Area Combining (‑SPA)
- Purpose and where it applies: Established along both sides of Francis Creek to protect riparian habitat and reduce erosion; mapped as a 50‑ft buffer from the top of bank or the edge of the riparian dripline—whichever is farther from the creek centerline (§ 6.08.1 ).
- Regulatory trigger:
- Development within the ‑SPA must comply with General Plan Land Use Element Goal LU‑4 policies, specifically LU‑3.4 (Francis Creek Corridor) and LU‑4.2 (Riparian Habitat/Erosion Control) (§ 6.08.2 ).
- Practical note: Because this overlay points to General Plan policies rather than parcel‑specific numeric standards, applicants should confirm current creekbank/dripline locations and any required studies or conditions with the City. Verify with the jurisdiction.

| ‑SPA Streamside Protection | Protect Francis Creek corridor | Base‑zone uses subject to GP policies | 50‑ft buffer from top of bank or dripline (whichever greater); comply with LU‑3.4 and LU‑4.2 | Expect project‑specific conditions coordinated with the City | § 6.08.1–.2 |
How overlay boundaries are determined
- All overlay boundaries are part of the official zoning map; they control just like base zones (§ 4.03–§ 4.04 ).
- Where boundaries are uncertain, the code provides rule‑of‑construction tools (e.g., street centerlines, lot lines) (§ 4.05 ).
- For ‑SPA, the buffer is measured from top of bank or riparian dripline, whichever is farther—field verification may be needed (§ 6.08.1 ).
Checklist
- Confirm all overlays affecting your parcel on the zoning map; note any B‑subzone, ‑Q, ‑D, ‑A, ‑H, or ‑SPA designations (§ 4.02–§ 4.04 ).
- If mapped ‑D, prepare a Ferndale Design Review submittal; plan your schedule so a building permit can be pulled within 6 months of approval, or request a one‑time 6‑month extension in advance (§ 6.05.2, § 6.05.4; timing/extension rules ).
- If mapped ‑B, apply the B‑subzone lot area and yard standards instead of the base zone’s numbers (§ 6.03 ).
- If mapped ‑Q in a commercial base zone, check whether your use is by‑right or needs a Use Permit; confirm Ferndale Parking compliance (§ 6.06.1–.3 ).
- If mapped ‑A, confirm livestock limits and setbacks for barns/pens; some ag‑related uses require a Use Permit (§ 6.02.2–.3 ).
- If within ‑SPA, measure the 50‑ft buffer from top of bank or dripline and coordinate with the City on applicable General Plan policies (§ 6.08.1–.2 ).
- If mapped ‑H near Fairview Dr./Trident Ln., note that existing duplexes are the focus; confirm any proposed changes with staff (§ 6.07; Verify with the jurisdiction ).
- Where overlays restrict new uses but you are an existing conforming use under the base zone (e.g., ‑Q), check continuation/expansion rules and, if needed, Use Permit findings in Article 10; see also Ferndale Nonconforming Uses (§ 6.06.3.c; § 10.06 ).
Risks & Ambiguities
| Issue | Why it matters | What to verify |
|---|---|---|
| Unclear overlay boundary on a parcel edge | Determines if overlay rules apply | Check the zoning map and apply § 4.05 boundary rules; request staff confirmation if needed (§ 4.03–§ 4.05 ). |
| Which standards control: base vs. overlay | Wrong standards can lead to redesign | Overlays control only the items they regulate (e.g., yards in ‑B; use limitations in ‑Q); apply base standards for everything else (§ 6.03; § 6.06.3.a ). |
| Design Review timing in ‑D | Permit expiration can stall projects | Pull a building permit within 6 months of Design Review approval or secure the one‑time 6‑month extension (§ 6.05, timing/extension ). |
| “Other compatible uses” under ‑Q | Discretion can affect feasibility | Whether a use is “similar/compatible” is a Planning Commission finding; discuss early (§ 6.06.2.l; Use Permit findings § 10.06 ). |
| Measuring the ‑SPA buffer | The wider of top‑of‑bank or dripline governs | Field conditions change; confirm measurement basis and any submittal requirements (§ 6.08.1–.2; Verify with the jurisdiction ). |
| Scope of ‑H overlay | It is narrowly drafted for existing duplexes | Whether new construction is allowed is not detailed; confirm intent and mapping limits (Not found in retrieved materials; § 6.07. Verify with the jurisdiction ). |
Plain-English Summary
Think of Ferndale’s combining zones as “overlays” that add extra rules where needed. Some change setbacks and lot sizes (‑B), some require design review to protect historic character (‑D), some tailor uses in residentially sensitive areas (‑Q), and others protect special resources like Francis Creek (‑SPA). Always check your map layer and then apply the overlay’s rules alongside your base zoning.

Frequently asked questions
Does Ferndale actually have overlay districts, and what are they called?
Yes. Ferndale calls them “combining zones.” The overlays are ‑A, ‑B, ‑X, ‑D, ‑Q, ‑H, and ‑SPA, established in § 4.02, with parcel boundaries on the zoning map (§ 4.03–§ 4.04) .
What changes when my lot has a B‑overlay like B‑2 or B‑4?
A B‑overlay replaces your base‑zone minimum lot area and yard setbacks with the B‑table values. For example, B‑2 requires a 10,000 sq ft site, a 25 ft front yard, side yards at 10% of lot width (min 10 ft), and a 10 ft rear yard (§ 6.03) .
I’m in a commercial zone but mapped with ‑Q. Can I open a shop?
Maybe. ‑Q limits commercial uses where residential uses predominate. Some small‑scale retail and services are allowed only with a Use Permit; single‑family dwellings are typically by‑right in ‑Q areas (§ 6.06.1–.2). Parking must meet § 7.16 (§ 6.06.3.b) .
Do I need design review in the ‑D overlay, and how long is approval valid?
Yes. Any exterior change (including signs) generally needs a Design Review Permit unless exempted. If a building permit is required and not pulled within 6 months of approval, the Design Review Permit expires; staff can grant one 6‑month extension if requested before expiration (§ 6.05.2; § 6.05.4; timing/extension) .
What exactly is protected by the ‑SPA Streamside Protection overlay?
The ‑SPA extends along Francis Creek, covering a 50‑ft buffer measured from the top of bank or the riparian dripline—whichever is farther from the creek centerline. Development must follow General Plan policies LU‑3.4 and LU‑4.2 (§ 6.08.1–.2) .
Can existing commercial uses continue in a ‑Q area if they no longer fit the overlay?
Yes. If they conformed to the base zone when the overlay took effect, they may continue and are not treated as nonconforming solely due to ‑Q. Expansion may be allowed via Use Permit if consistent with ‑Q’s purpose (§ 6.06.3.c) .
What ag activities are allowed in the ‑A overlay?
General agriculture and certain livestock are allowed, with numeric limits (e.g., up to 5 sheep/goats per ½ acre; up to 200 small animals like rabbits/chickens per ½ acre). Some ag retail and animal categories require a Use Permit; barns/pens must observe setbacks (§ 6.02.1–.3) .
Where does the ‑H Housing overlay apply, and can I add more units there?
It is intended for the existing duplex units on part of the Ferndale Housing Project site on Fairview Drive and Trident Lane, principally permitting those existing duplexes. Whether additional units are allowed is not specified—Verify with the jurisdiction (§ 6.07) .
