Overview

This page explains how Red Bluff’s local zoning (commonly titled the zoning ordinance, Article/Chapter references beginning with § 25.) controls what uses are allowed on property in each zone, when a Conditional Use Permit (CUP) or Administrative Use Permit (AUP) is required, and which dimensional standards typically apply. For a quick map-level check start at the city's zoning overview. All requirements below are taken from the local zoning ordinance (Title 25 / “Zoning”) that the city enforces (citations given inline).

How the ordinance organizes land use

  • Allowed/conditional uses are listed in a use-zone matrix and topic-specific use tables; the ordinance distinguishes P (permitted), CUP (conditional use permit), AUP (administrative use permit) and N (not allowed) across zones (see the use tables and notes for the matrix) § 25.09.35 .
  • General applicability and required compliance items (setbacks, lot size, parking, landscaping, etc.) are mandatory for any new use; see § 25.01.5 and related administrative provisions § 25.01.3 .
  • Where off-street parking is relevant, follow the local parking rules in Article XXIII referenced by the commercial and other district rules § 25.08.22 .
  • Commercial and other development must typically comply with the city’s design review rules and the development standards tables (see the development standards charts called out in each district) § 25.08.30; § 25.08.24 .

Below is a district-by-district synthesis (what the ordinance actually says).

District-by-district breakdown

Note: for any parcel, “where it applies” is simply “on parcels zoned” to that district. Verify the parcel zoning with the Community Development Department.

Residential districts — R-1, R-2, R-3, R-4

Purpose and overview

  • The R districts are the city’s residential zones; they carry zone-specific lot and yard standards and are the baseline for single- and multi-family housing. All residential development must comply with the residential lot and yard tables in Article VI § 25.06.40 .

Typical permitted and conditional uses

  • Dwelling units, accessory residential uses, and limited neighborhood services per the use-zone matrix; accessory farm animals and small kennels are specifically addressed with limits (e.g., up to 50 poultry/rabbits; commercial kennels >10 dogs require a CUP) § 25.11.7 .
  • Planned developments may include any uses permitted in the district (and limited cross‑district exceptions) per the planned development rules § 25.14.3 .

Key dimensional standards (examples from the ordinance notes)

  • Minimum side yard: 5 ft and add 3 ft for each additional story above the first; minimum front yard may be 10 ft (where alley access) or 20 ft otherwise; detached accessory buildings side/rear yards 3 ft minimum. See the residential lot standards table § 25.06.40 .
  • General minimum lot areas, parking counts, landscaping, and building coverage are set in Article VI; parking cross-references Article XXIII § 25.06.40 .

Where it applies

  • City parcels zoned R-1, R-2, R-3 or R-4; planned development rules allow some cross-over subject to findings § 25.14.3 .

Commercial districts — C-1, C-2, C-3, FC (Freeway Commercial), HC (Historic Commercial)

Purpose and overview

  • Commercial districts regulate neighborhood retail, downtown core activities, general commercial services and freeway-oriented uses. The commercial article requires compliance with development standards and design review (commercial lot standards and design guidelines) § 25.67; § 25.08.24; § 25.08.30 .

Typical permitted and conditional uses

  • Use‑zone tables show which retail, service, office, vehicle service, and specialized uses are permitted in C-1/C-2/C-3; many vehicle/repair and shop uses are allowed with varying CUP/AUP triggers — consult § 25.08.35 and the table in § 25.79 for the commercial use matrix § 25.08.35; § 25.79 .
  • Cannabis-related uses are restricted and must comply with Chapter 6B as noted in the commercial notes § 25.09.35 .

Key dimensional and procedural standards

  • Front/side/rear yards, building coverage and heights are governed by the “commercial lot standards” charts called out in § 25.79; off‑street parking per Article XXIII applies § 25.08.24; § 25.08.22 .
  • Signage follows the city sign code; design review usually applies to commercial projects § 25.08.28; § 25.08.30 .

Where it applies

  • Parcels zoned C‑1, C‑2, C‑3, FC, HC; see the permit table in § 25.79 for zone‑by‑zone permitted/conditional uses § 25.79 .

Industrial districts — M-1, M-2, P-I (Planned Industrial / Public‑Industrial standards)

Purpose and overview

  • Industrial zones accommodate light and general industrial, repair, storage and other higher‑impact uses. The ordinance lists permitted/conditional uses and includes an industrial lot standards table § 25.09.35; § 25.93 .

Typical permitted and conditional uses

  • Warehousing and low‑impact storage often P; high‑impact storage, vehicle impound yards and some outdoor industrial activities are CUP‑regulated — consult the M‑zone matrix § 25.09.35 .

Key dimensional standards (from the industrial lot standards table)

  • M‑1: Front yard 5 ft, Side yard none, Rear yard 5 ft, Min lot area 6,000 sf, Max building coverage 65%, Max height ~50 ft (notes apply) § 25.93 .
  • M‑2: similar but allows larger building coverage and greater height in some cases (Max building coverage 70%, height up to 60 ft) § 25.93 .

Where it applies

  • Parcels mapped M‑1, M‑2, or other industrial designations in the zoning map; special industrial lot standards sit in § 25.93 .

Public and special districts — A‑V, P‑A, Airport and Combining Districts (AZ, FP, FW, MHCA)

Purpose and overview

  • Public zones (such as A‑V, P‑A) and combining districts implement agency, airport, and floodplain land‑use controls and require agency‑specific review; permitted public uses are listed in the public agency tables § 25.10.35; § 25.104 .

Typical permitted and conditional uses

  • Schools, police/fire stations, airports/heliports, drainage facilities, parks, and municipal storage/maintenance structures are explicitly listed as P or CUP in the public use tables § 25.10.35 .

Key controls and overlays

  • The AZ (Airport Approach Zone) combining district requires conformance with the airport land use plan and usually an aviation easement for parcels within an approach area § 25.11.11 .
  • Floodplain overlays (FP) and floodway overlays (FW) require compliance with the city’s Chapter 26 flood regulations § 25.11.13; § 25.11.14 .

Where it applies

  • Applied as shown on the zoning map and by combining district maps; where a combining district is present, both base zone and overlay rules apply.

Planned developments and setback adjustments (tools developers use)

  • Planned developments: a process allowing design flexibility where the Planning Commission can grant use permits that may alter certain dimensional standards if objectives are met (planned development rules and permitted-use exceptions) § 25.137 – § 25.141; the ordinance requires the PD to include only uses permitted in the base district (with the stated exceptions) § 25.138 .
  • Setback adjustments: the code provides an administrative/Planning Commission pathway for setback reductions subject to conditions (minimums cannot go below specified absolute minima—e.g., residential constructions not closer than 8 ft front/rear, 3 ft side) § 25.158 and application procedures § 25.159 .

Quick reference table — selected decision‑relevant standards and uses

Topic Rule / Typical value or trigger Code reference
Side yard minimum (residential) 5 ft; add 3 ft per story above first (detached accessory bldg side/rear 3 ft) § 25.06.40
Planned development allowed cross‑uses PD may include uses permitted in base district; limited cross‑district exceptions for R and C categories § 25.138 (planned development permitted uses)
Commercial setbacks/building coverage/height Follow “commercial lot standards” charts—see § 25.79; design review typically applies § 25.08.24; § 25.79; § 25.08.30
M‑1 front/side/rear setbacks & coverage Front 5 ft; Side none; Rear 5 ft; Max coverage 65%; Min lot 6,000 sf § 25.93 (industrial lot standards)
Off‑street parking requirement cross‑reference See Article XXIII; commercial/industrial tables reference Article XXIII for minimums § 25.08.22
Airport overlay requirement Aviation easement and compliance with airport land use plan for parcels in approach zone § 25.11.11 (AZ combining district)
Cannabis uses Must comply with Chapter 6B; use allowed varies by commercial zone § 25.09.35 (notes)

Checklist — what an applicant must satisfy (high‑level)

  • Confirm the parcel’s base zone and any combining/overlay districts with Community Development (verify zoning map) § 25.01.5 .
  • Consult the use‑zone matrix / specific district use table (is the proposed use P, CUP, AUP, or N?) § 25.08.35; § 25.09.35; § 25.10.35 .
  • Produce a site plan showing setbacks, parking (see parking) and landscape areas — parking rules are enforced under Article XXIII § 25.08.22 .
  • Confirm whether design review applies and, if so, follow submittal standards (commercial and many multi‑unit projects) § 25.08.30 .
  • If use is conditional (CUP) or administrative (AUP), prepare supporting findings and neighborhood noticing; see planned development and use permit procedures § 25.137–§ 25.147 .
  • Check overlay/combining district constraints: airport, floodplain, mobile home common area (MHCA) rules may add requirements § 25.11.11; § 25.11.13; § 25.11.14; § 25.112 .
  • For uses not listed in tables, prepare a “similar use” justification per the ordinance (see similar‑use rule) § 25.183 (referenced in the matrix) .
  • Verify any state‑level requirements (for example ADUs and building‑code compliance) with the local ADU rules and the California Building Standards Code.

Risks & Ambiguities

Issue Why it matters What to verify
Use not listed in the matrix The code requires similar‑use interpretation; different staff/commission conclusions change permit outcome Check the “similar uses” provision referenced in the matrix and prepare a written comparison § 25.183 (matrix notes)
Parcel is in an overlay (airport/floodway) Combining districts can add easements or additional permit hurdles (airport easement, floodplain Chapter 26 compliance) Confirm overlay boundaries and read § 25.11.11, § 25.11.13 / § 25.11.14; verify with Community Development and airport land use plan
Conflicting references for dimensional relief Some PD or setback adjustments can waive standards but absolute minima remain § 25.158 If requesting reductions, follow the setback adjustment application steps and confirm absolute minima § 25.158 – § 25.160
Parking calculations for mixed uses Off‑street parking standards live in Article XXIII and are cross‑referenced by district; miscalculating stalls delays approvals Pull Article XXIII requirements and confirm which use table applies to mixed‑use calculations § 25.08.22
Cannabis and regulated industries Chapter 6B (cannabis) and other specialty chapters impose overlay or permit constraints not obvious in the zone matrix Verify Chapter 6B compliance and any caps or locational limits § 25.09.35 notes
ADUs / State law interactions State ADU rules can preempt local requirements, but local ordinance controls sit elsewhere Local ADU details were not located in the retrieved materials — Verify with the jurisdiction and the city ADU page ADUs. Not found in retrieved materials.

Plain‑English summary

The Red Bluff zoning code (Title 25) uses zone‑by‑zone use tables and district lot‑standard charts to say what you can build on any given parcel: residential zones allow housing with minimum yards/lot sizes; commercial zones allow retail and services but often require design review and parking; industrial zones allow warehouses and repair with specific setbacks and coverage limits. If a use is listed P, you follow the standards; if it’s CUP or AUP you need a permit; if it’s N it’s not allowed — consult the exact zone table referenced in the ordinance § 25.08.35; § 25.09.35; § 25.10.35 .

Frequently asked questions

What can I build on an R-1 lot in Red Bluff?

Most typical single‑family residential uses and accessory residential uses are allowed in R‑1; zone‑specific minimum yards, lot area and parking must be met (see residential lot standards § 25.06.40) and planned developments or nonstandard proposals follow the planned development and use permit rules § 25.138; § 25.06.40 .

What are Red Bluff setback requirements for houses?

The residential table sets minimums (example: side yard 5 ft with +3 ft per story above the first; front yard 10 ft where alley access or 20 ft otherwise). See the residential lot standards table § 25.06.40 for the full set of yard rules and notes .

Do I need a Conditional Use Permit (CUP) for a business in a C‑2 zone?

Check the commercial use table: uses are shown as P, CUP, AUP or N for C‑2 in the permit list; if the matrix shows CUP for your use, you must apply and meet the CUP findings § 25.79; § 25.08.35 .

Are there special rules if my lot is inside the airport approach area?

Yes. The AZ combining district requires compliance with the airport land use plan and an aviation easement prior to development permits on properties in the approach zone § 25.11.11 .

Where are the industrial zone setbacks and coverage limits stated?

Industrial lot standards (M‑1, M‑2, P‑I) including front/side/rear setbacks, minimum lot area and max building coverage are in the industrial lot standards table, § 25.93 .

How do I know whether my proposed use is treated as “high‑impact” storage or “low‑impact”?

The use tables mark “storage, high impact potential” as CUP in many zones and define examples/thresholds in the notes; the specific definitions and thresholds are cross‑referenced to the storage/industrial notes § 25.09.35; § 25.239 (cross‑reference) .

If a use is not listed in the matrix, what do I do?

The ordinance directs applicants to the “similar uses” rule and staff interpretation; prepare a written comparison to a listed use and request a determination under the code’s similar‑use provisions (matrix notes referencing § 25.183) .

Does commercial development always require design review?

Not always, but the ordinance states that “unless specifically exempted, all development proposals for commercial districts shall comply with the design review guidelines” — so expect design review for most commercial projects § 25.08.30 .

Are cannabis businesses allowed in Red Bluff?

Cannabis uses are treated specially: the commercial use notes indicate that cannabis uses must comply with Chapter 6B and that permissibility varies by commercial zone; check § 25.09.35 and Chapter 6B for specifics § 25.09.35 .

Can I reduce setbacks through a variance or PD?

Setback reductions can be sought via the setback adjustment procedures or as part of a planned development, but absolute minima cannot be violated and specific findings apply; see the setback adjustment and PD sections § 25.158 – § 25.160; § 25.137 – § 25.141 .
