Ceres — Land Use

Last reviewed: July 1, 2026

Overview

This page summarizes how the City of Ceres regulates land use in its zoning ordinance (commonly adopted as a Title 18 zoning code). It focuses strictly on what the local ordinance permits, conditions, or prohibits in each zone and where to look for dimensional and process rules. For site design and compliance you will also need to review the city's development standards, parking, and design review rules referenced below.

How the ordinance controls land use (summary)

• Uses are organized by zone: residential, commercial, industrial, and planned-community districts list permitted principal uses, accessory uses, and conditional uses (CUPs) in each district text (see the district chapters; e.g., R-1 § 18.08.* and C-2 § 18.16.*) .
• Uses listed in a zone as "conditional" require a CUP; the standards and findings for CUPs are in § 18.30.020 and related CUP sections (temporary uses and administrative CUPs are separately listed) .
• Many district chapters allow the Director or Planning Commission to find "similar" uses acceptable or to impose special site standards; where language is permissive, the code points you to the applicable property development standards chapter for numeric rules (setbacks, lot coverage, heights) — e.g., see each zone's property standards reference (for example § 18.19.060 for M-1) .
• Accessory dwelling units are explicitly permitted as accessory uses in multiple zones but are subject to the ADU rules referenced in § 18.28.060 (see the local ADU requirements and the city's ADU page) .

Below is a district-by-district practical breakdown (purpose, typical permitted uses, where it applies, and the controlling code references). Bolded district names and standards highlight what applicants scan for.

R-A (Rural/Agricultural)

Purpose: Preserve agricultural and low‑intensity rural uses while limiting residential and commercial uses in those areas. See § 18.07.010–§ 18.07.060 for standards and limitations (lot sizes, setbacks).

Typical permitted uses:

• Farm and ranch uses, limited rural residential uses; accessory agricultural structures (permitted list in the chapter). See § 18.07.020–§ 18.07.060.

Key dimensional standards (code references):

• Minimum lot area: 1 acre for principal uses (§ 18.07.060.A)
• Maximum lot coverage: 15% (plus an extra 10% allowance for accessory structures on single‑family lots) (§ 18.07.060.B)
• Front setback: 25 ft (accessory structures: more restrictive rules apply) (§ 18.07.060.D)

Where it applies: Outlying parcels designated R‑A on the zoning map; verify the parcel's zoning with the City.

R-1 (Single‑Family Residential)

Purpose: For single‑family neighborhoods and related residential support uses (§ 18.08.010)

Typical permitted uses:

• Single‑family detached dwellings, customary residential accessory uses, garages, pools, home occupations, ADUs (subject to § 18.28.060) (§ 18.08.030)

Conditional uses and prohibitions:

• Conditional uses include schools, churches (on lots <1 acre), public parks, licensed child care and hospitals (§ 18.08.040)
• Prohibited: multiple dwellings are expressly prohibited in R‑1 (§ 18.08.050)

Key dimensional standards:

• See the property development standards for R‑1 (setbacks, lot coverage, height) referenced in the R‑1 chapter; accessory rules (garages, pools, ADUs) are in § 18.08.030 and the ADU chapter § 18.28.060 (§ 18.08.* and § 18.28.060)

R-3 (Medium‑Density Multiple‑Family)

Purpose: Allow medium (7–12 du/acre) multiple‑family housing and associated services (§ 18.10.010)

Typical permitted uses:

• Single‑family, two‑family, and medium‑density multi‑family dwellings and related uses listed in § 18.10.020; accessory uses subject to § 18.10.060 standards.

Key dimensional standards:

• Property development standards are set in § 18.10.060 (lot area, setbacks, lot coverage) — consult that section for numeric minimums and site design requirements (§ 18.10.060)

R-4 (Medium‑High Density Multiple‑Family)

Purpose: Support higher‑density multi‑family residential (see § 18.11.*) for compact housing forms and required services.

Typical uses and standards:

• See § 18.11.010–§ 18.11.060 for permitted uses and development standards; recreation, parking, and solid‑waste requirements are addressed in the chapter (§ 18.11.*)

C-1 (Neighborhood/Convenience Commercial)

Purpose: Convenience‑oriented retail and services serving neighborhoods (§ 18.15.010)

Typical permitted uses:

• Banks, pharmacies, small grocery and retail shops, restaurants (limits on alcohol or entertainment described in the chapter), child care, and other neighborhood services (§ 18.15.020)

Key rules:

• Storage and most operations must be conducted within a building except certain outside displays (see § 18.15.020 and the property development standards § 18.15.060)

C-2 (Community Commercial)

Purpose: Larger community commercial uses and administrative/professional uses (§ 18.16.010)

Typical permitted uses:

• All A‑P and C‑1 principal uses, department stores, restaurants (including alcohol in certain cases), liquor stores, and general retail/service uses (§ 18.16.020)

Accessory and conditional uses:

• Accessory residential uses, small storage structures, parking and loading areas (see § 18.16.030 and parking rules in § 18.26.120.L), and conditional uses like automobile service stations and dry cleaning plants (§ 18.16.030–§ 18.16.040; § 18.26.120.L)

C-3 (Wholesale/Heavy Commercial)

Purpose: Concentration of wholesale and heavy commercial activity; most storage must be indoors (§ 18.17.010–§ 18.17.020)

Typical permitted uses:

• Auto sales, building material yards, appliance/furniture sales, equipment rental, repair shops, public storage, and related heavy commercial uses described in § 18.17.020

Key rule:

• Outdoor storage and displays are limited; most uses and storage must be totally enclosed except specified exceptions (§ 18.17.020)

M-1 (Light Industrial)

Purpose: Light and specialized industrial, administrative, and R&D uses (§ 18.19.010)

M-2 (General Industrial)

Purpose: Heavy or general industrial processes that may require more separation from residential uses (§ 18.20.*)

Typical uses and conditional processes:

• Broader manufacturing with explicit conditional lists (chemical processes, large‑scale manufacturing) often require location >500 ft from residential zones or a CUP (§ 18.20.040)

P‑C (Planned Community)

Purpose: Flexible, master‑planned development with its own master plan and possible variation of standards; requires a master plan and may permit mix of residential, commercial, public uses (§ 18.13.010–§ 18.13.030)

Key rules:

• Minimum parcel size for P‑C: 1 acre; P‑C may allow accessory uses including ADUs, mobile home parks, and adult businesses where consistent with the general plan and master plan; master plan and development plan reviewed by Planning Commission and City Council per § 18.13.030

Checklist — what an applicant must satisfy (typical)

• Confirm zoning for the parcel and verify that the proposed use is listed as a permitted principal use or an accessory use in the zone chapter (see the zone chapters cited above; e.g., § 18.08.030 for R‑1) .
• If the use is listed as a conditional use, prepare a CUP submittal addressing the findings in § 18.30.020 (and related CUP procedures) .
• Demonstrate compliance with property development standards — setbacks, lot coverage, height — in the zone's development standards chapter (e.g., § 18.07.060, § 18.08.*, § 18.19.060) .
• Provide required parking calculations and layout per the city parking standards (see parking and the code cross‑references such as § 18.26.120.L) .
• Address service functions: off‑street loading, solid waste storage and screening per the applicable sections (e.g., off‑street loading standards referenced in the zone chapters and § 18.26.120.M) .
• If the site is in a P‑C or overlay district, include master plan or overlay compliance as required (P‑C master plan per § 18.13.030 and overlay rules per the city's overlay district chapter) .
• If seeking an exception such as a variance, follow the variance rules in the code and consult the variances and exceptions guidance.
• For ADUs, follow local ADU rules and the statewide ADU law — local code cross‑references ADUs to § 18.28.060 (see the city's ADU page for application steps) .

Risks & Ambiguities

Plain‑English Summary

Ceres lists allowed and conditional activities by zoning district in Title 18: you must check the parcel's zone, confirm the use is permitted (or be ready for a CUP), and meet the numeric property standards and parking/loading requirements the zone points to — for example, R‑A requires 1‑acre minimum lots and R‑1 is limited to single‑family homes (ADUs allowed as accessory). Always verify the specific numeric standards in the zone's property development standards section and get a pre‑application check with the city for ambiguous "similar use" situations (§ 18.07.060; § 18.08.030; § 18.30.020) .
