Yuba City — Overlay Districts

Last reviewed: July 3, 2026

Overview

Yuba City's zoning ordinance implements several combining/overlay districts (called "combining districts" in the Code) that sit on top of the base zoning map to add location‑specific rules or incentives. The principal overlays in the Code are the Agricultural Combining District (A), Airport Influence Combining District (AI), Historic Combining District (H), Special Standards Combining District (X), and Specific Plan Combining District (SP); the Flood District (F) is treated as a district with special flood standards. The ordinance explains purpose, how overlays interact with the base zone, and the procedures to create or remove an overlay; see the district list at § 8-5.105 .

Notes on reading this page

• Every requirement below is referenced to the Yuba City Zoning Code. Where the Code delegates standards to another chapter (for example flood rules in Title 6), I note that delegation and cite the controlling §. Verify parcel‑specific overlay boundaries with the City’s official district map (on file with the City Clerk and Planning Director) as required by § 8-5.106 .
• Links: the first natural mention of related topics below are linked to the relevant GoCodebook pages: development standards, design review, parking, ADUs, California building codes, and historic preservation.

How the overlays work (general rule)

• Overlays are combined with a base district; the base district's permitted uses and standards apply unless the overlay states otherwise or a specific plan/combining district explicitly prevails. See § 8-5.3903 for the Specific Plan rule that the specific plan controls when in conflict, and § 8-5.3802 for the Special Standards fallback that uses of the base district continue to apply unless limited by the overlay .
• Where a combining district imposes unique criteria or requires additional findings, rezoning to or establishment of the combining district is processed as an amendment to the Zoning Code under the procedures for map changes (Article 72). See § 8-5.3804 and § 8-5.3904 .

District-by-district breakdown

Note: each subsection lists the Code purpose, typical permitted uses (as written), key dimensional or procedural standards, and where the overlay typically applies.

Agricultural Combining District (A)

• Purpose: To permit limited raising of farm animals where lot size makes that use appropriate without creating a nuisance; see § 8-5.3501 .
• Typical permitted uses: All uses of the underlying base zone; plus expressly listed agricultural activities such as crop and tree farming, livestock farming, poultry/rabbit farming, and sale of on-site agricultural products (subject to limits and review levels) — see § 8-5.3502 .
• Key dimensional/operational limits (bolded where decision‑relevant):
  • Structures for animals (barns, stables, coops, kennels) must be at least 35 ft from any property line and 40 ft from any dwelling (§ 8-5.3503) .
  • Animal density limits: not more than one large animal per 0.5 acre (specific allowable mixes enumerated) and a use permit is required for large‑scale poultry/rabbit operations; see § 8-5.3502(3–4) .
• Where it applies: Rezoned onto parcels where existing lot size and proximity make limited agricultural uses appropriate; creation/disestablishment follows standard rezoning procedures (rezone application plus materials) — see § 8-5.3503 and establishment rules in Article 35 .

Airport Influence Combining District (AI)

• Purpose: Implements the Sutter County Airport Comprehensive Land Use Plan (CLUP) to avoid incompatible development in overflight zones — § 8-5.3601 .
• Typical permitted uses: All uses of the base district remain allowed provided the use conforms to the compatibility criteria in the CLUP; the overlay does not create a new use list but conditions uses to the CLUP compatibility standards (§ 8-5.3602) .
• Key procedural and numeric controls:
  • Projects within the AI overlay are subject to pre‑review by the Airport Land Use Commission (ALUC) when required by the CLUP; if ALUC finds a project inconsistent, City must follow that finding unless the City Council overrules for hardship (§ 8-5.3603) .
  • For height/airspace restrictions, see the Airport Zoning chapter (Chapter 3) because that chapter sets height surfaces (approach, transition, turning zones) and numeric slope/height limits (e.g., zero ft at runway end increasing at 1 ft vertically per 20 ft horizontally up to 150 ft in some zones) — see 8-3.04–8-3.05 .
• Where it applies: Properties inside the airport overflight/approach zones shown on the Official Airport Zoning Map; verify with the City’s map and the CLUP before permitting — see § 8-3.04 and § 8-5.3601–3603 .

Historic Combining District (H)

• Purpose: Preserve and manage rehabilitation/restoration of historic resources and implement General Plan historic resource policies (§ 8-5.3701) .
• Typical permitted uses: All uses and development standards of the base district continue to apply; uses that would adversely affect the historic resource can be limited and alterations are reviewed for conformance with the previously prepared historic report and Secretary of the Interior’s Standards (§ 8-5.3705) .
• Key standards / procedures:
  • Rezoning into H requires a rezone application with a site plan, photographs, and professional historic documentation; the Historic Preservation Review Committee reviews candidates before formal submittal (§ 8-5.3703 and related subsections) .
  • Exterior modifications that require a building permit for a recognized historic building are subject to administrative design review; if staff finds proposed changes may harm character‑defining features the proposal goes to the Historic Preservation Review Committee (§ 8-5.3708) .
  • Exception: Certain architectural elements (towers, spires, cupolas) may be allowed up to 25 ft above the underlying district height limit if historic documentation supports it (§ 8-5.3705(b)) .
• Where it applies: Properties rezoned by the City Council to H; incentives and procedures are set out in Article 37 and tied to the City’s historic inventory — see § 8-5.3701–3709 . For administrative design review rules see the City’s design review overview linked below.

Special Standards Combining District (X)

• Purpose: Two uses — (1) a City tool to apply parcel‑specific development criteria not needed citywide, and (2) an optional way for applicants to propose innovative, higher‑quality deviations from standard development metrics (the district is explicitly not intended to reduce standards) (§ 8-5.3801) .
• Typical effect: Does not change the underlying use list except to limit uses if the combining standards so state; density/intensity remains subject to the General Plan and findings must be made for a combining zone adoption (§ 8-5.3802–3806) .
• Key procedural requirements:
  • Establishment is an amendment to the Code and processed using Article 72 procedures (§ 8-5.3804). The approving authority must find consistency with the General Plan and that the proposed revisions will not create incompatibilities (§ 8-5.3806) .
• Where it applies: Applied to specific parcels as a rezoning tool (map amendment) to fine‑tune development standards or authorize alternative site designs. Because the overlay can change setbacks, lot coverage, or similar metrics, confirm all modified standards in the adopted combining text — see § 8-5.3804–3806 .

Specific Plan Combining District (SP)

• Purpose: Ensures development within an area subject to an adopted specific plan meets the plan's standards; SP can be combined with any base district inside a specific plan boundary (§ 8-5.3901) .
• Typical permitted uses and standards:
  • All permitted uses and use permit uses of the base district continue unless the specific plan identifies different allowed uses; the specific plan controls in a conflict (§ 8-5.3902–3903) .
  • Permit type and review process for site improvements are dictated by the base district and the specific plan (and specific plan may establish its own review body to advise the decision‑maker) (§ 8-5.3904) .
• Where it applies: Parcels located wholly or partially within boundaries of an adopted specific plan; check the City’s specific plan documents and the combined zoning shown on the district map — see § 8-5.3901–3904 .

Flood District (F) (why it matters as an overlay/district)

• Purpose: Allows limited use of land in mapped floodplain consistent with minimizing hazards; flood standards and technical elevation requirements are implemented in Title 6 (Flood Damage Prevention) as referenced by the zoning Code (§ 8-5.2601 and cross‑reference in many district development standards) .
• Key action items: Any development in F must comply with the City’s flood standards (Title 6) — verify base flood elevation requirements, building elevation, and whether a levee fee or floodproofing is triggered; see the cross‑references in the district standards (e.g., flood standard references in multiple district tables) .

Quick reference table — most decision‑relevant rules

Practical guidance (plain‑English, for applicants)

• Always check both the base zone and the overlay text: the overlay may add procedural steps (for example, ALUC review for AI or design review for H) or change standards (for X or a Specific Plan). See § 8-5.3903 and § 8-5.3801 .
• For projects on a parcel with H or in a specific plan, expect extra submittal requirements (photos, historic report, elevations or narrative) and possible referral to a committee; see § 8-5.3703–3708 and § 8-5.3904 .
• If you want to use the flexibility of a Special Standards (X) overlay to vary setbacks or coverage, plan a rezoning package and be prepared to demonstrate that your alternative produces equal or better quality and is consistent with the General Plan (findings in § 8-5.3806) .
• For properties near the airport, build the CLUP compatibility test into feasibility early; an ALUC negative finding can essentially block a zoning amendment unless the Council makes a hardship finding — § 8-5.3603 .

Helpful links (first mention)

• The ordinance ties overlay development to the City’s development standards and to procedures including design review. See the City’s rules on parking and ADUs because overlays often reference those standards. Work that requires a building permit still must comply with the California Building Standards Code. If your proposal involves historic resources, read the City’s historic preservation rules early.

Checklist — what an applicant must satisfy for an overlay‑affected project

• Confirm overlay(s) on the parcel using the official district map (on file as required by § 8-5.106) .
• Identify the base zone and list of permitted uses — compare with overlay limitations (see the applicable combining district §§: § 8-5.3501–3503, § 8-5.3601–3603, § 8-5.3701–3709, § 8-5.3801–3806, § 8-5.3901–3904) .
• Prepare required submittal materials (site plan, elevations, historic report if H, specific‑plan compliance materials if SP) — see § 8-5.3703 and § 8-5.3904 .
• Identify required referrals (ALUC for AI; Historic Preservation Review Committee for H) and schedule accordingly (§ 8-5.3603, § 8-5.3709) .
• Check cross‑references: flood zone rules (Title 6) for F; parking, landscaping, signage and other development standards referenced in the applicable district tables (see district tables and cross‑refs in Articles 11–26) .
• If seeking modified standards via X, prepare General Plan consistency analysis and justification for quality equivalency per § 8-5.3806 .

Risks & Ambiguities

Plain‑English summary

Yuba City’s overlays (combining districts) — notably A, AI, H, X, SP, and F — layer additional use, setback, or process rules onto the base zoning. They are implemented by rezoning/map amendment, can require external reviews (ALUC, Historic Committee), and in some cases (Specific Plans) the overlay’s standards will control over the base zone; see the identified Code sections for the exact tests and procedures such as § 8-5.3501–3503, § 8-5.3601–3603, § 8-5.3701–3709, § 8-5.3801–3806, and § 8-5.3901–3904 .
