Bell Zoning, Planning & Building Codes

Last reviewed: July 1, 2026

Overview

Bell regulates land use through Title 17 of its municipal code, the city’s Bell Zoning ordinance. Title 17 identifies the city’s base zoning districts, overlay zones, review procedures, and citywide standards for yards, height, design, and parking requirements. The code is explicit about when projects need ministerial zoning clearance versus discretionary site plan review, and where overlays (Planned Development and Mixed-Use) can flex or layer standards. The city also codifies how ADUs are processed to comply with state law, and requires a specific plan for large (4+ acre) sites.

How Bell’s code is organized

• Title 17 is the zoning title and may be cited as the “Bell zoning code.” Chapter 17.04 contains general provisions and sets minimum requirements, treatment of existing variances/CUPs, and continuity of nonconforming status rules.
• Chapter 17.12 establishes the city’s base zones and the official zoning map; R-1 is the most restrictive.
• Zone chapters then follow: R-1 (Ch. 17.16), R-2 (Ch. 17.20), R-3 (Ch. 17.24), C-3R (Ch. 17.28), C-3 (Ch. 17.32), M (Ch. 17.40), and T Transitional (Ch. 17.44), each with permitted uses and development standards. Examples: R-3 standards at §17.24.050; M standards at §17.40.040.
• Overlay districts include the Planned Development (PD) overlay (Ch. 17.48) and the Mixed-Use Overlay (MUOZ) (Ch. 17.49).
• Citywide standards live in Chapter 17.52 (general design/yard rules), Chapter 17.76 (off-street parking and loading), Chapter 17.88 (landscaping), and Chapter 17.25 (exterior color review in commercial/manufacturing areas).
• Process chapters include Chapter 17.92 (site plans and zoning clearance) and Chapter 17.96 (variances and conditional use permits).

Zoning district families

Bell’s base zones are designated in §17.12.010: R-1, R-2, R-3, C-3R, C-3, C-M, M, and T. The code ranks R-1 as the most restrictive.

Residential districts

• R-1 (Single-Family Residential). Typical lots must be at least 5,000 sf and 50 ft wide; the district sets a 25 ft front yard, 5 ft interior sides (street side 10 ft), and a 10 ft rear yard. Height is capped at 2 stories/30 ft for primary structures and 15 ft for accessory buildings. Off-street parking is required per Chapter 17.76.
• R-2 (Light Multiple Residential). Height is limited to 2 stories/30 ft, with accessory buildings up to 15 ft. The code includes side yard adjustments for sub-50-foot lots and establishes off-street parking by cross-reference to Chapter 17.76; front-yard landscaping and hardscape limits also apply.
• R-3 (Heavy Multiple Residential). New lots must be at least 7,200 sf and 60/65 ft wide (interior/corner); density is one dwelling unit per 1,452 sf of lot area. Lot coverage is capped at 50% and height at 3 stories/35 ft (accessory height limits vary, with ADUs governed by §17.54.050(E)). Parking is per Chapter 17.76.

Commercial and manufacturing districts

• C-3R (General Commercial and Residential). The district allows a wide range of commercial uses (and residential by CUP) with development standards that include: for commercial, a 10 ft landscaped front setback; 10 ft side yard when adjoining R zones; 10 ft rear (or 5 ft when separated by an alley); maximum height 70 ft with R-1 adjacency step-down. Parking and loading are per Chapter 17.76, and site plan review is required before a building permit.
• C-3 (General Commercial). Permitted uses are detailed extensively in Chapter 17.32; refer to the chapter for the use list and applicable standards.
• C-M (Commercial Manufacturing). Industrial-intensity uses in C-M and M zones are controlled by special approvals for certain activities (e.g., hazardous waste facilities require a CUP and must locate in C-M or M).
• M (Manufacturing). No front yard is required unless a driveway enters the front wall (then 20 ft minimum); side and rear yards are 10 ft when abutting R zones (rear can be 5 ft if separated by an alley). Height is up to 70 ft, with step-down to R-1 limits within 50 ft of an R-1 lot line. Parking/loading per Chapter 17.76; site plan review is required before building permit.

Special purpose district

• T (Transitional). A tailored zone tied to the Bell Federal Service Center property and its potential reuse; the findings section explains why additional controls are needed due to the site’s size and impacts.

Citywide development standards

• General design and yard rules. Chapter 17.52 applies citywide unless stated otherwise: it clarifies that required yards must be open to the sky, provides “vision clearance” triangles on corners (15 ft legs at 42 in max height), and allows screened mechanicals/roof structures to exceed height limits in C and M zones.
• Definitions and yard measurement. Definitions for “front,” “side,” and “rear” yards clarify how to measure setbacks.
• Off-street parking and loading. Every principal use must provide and maintain off-street parking and loading per Chapter 17.76. The schedule is in §17.76.020 (e.g., commercial ratios scale by building size in C zones).
• Landscaping and screening. Chapter 17.88 outlines landscape/irrigation design with water-conservation measures and planting guidance.
• Exterior color review (commercial/manufacturing). Chapter 17.25 requires exterior color review with many entitlement types; appeals can reach the city council. Nonconforming exterior colors must be abated within three years after notice.

Examples at-a-glance (selected districts):

• The R-1 district sets a 25 ft front setback, 5 ft interior side, 10 ft street side, 10 ft rear, and a 30 ft/2-story height cap.
• The R-3 district limits lot coverage to 50%, height to 35 ft/3 stories, and requires one unit per 1,452 sf of lot area.
• The M district allows up to 70 ft height (with adjacency step-down), no front yard unless a driveway penetrates the façade (20 ft then), and 10 ft side/rear abutting R districts.

Specific plans & overlays

• Specific plans for large sites. A specific plan is required for any development of 4 acres or more; applicants must deposit estimated preparation costs, and the process follows Gov. Code §65450 et seq.
• Overlay Districts
  • Planned Development (PD) overlay (Ch. 17.48). Allows a precise plan of development; properties carry the “PD” suffix on the map. Uses remain limited to those allowed in the underlying zone, but an approved plan can supersede certain development standards. Plans expire if not commenced within 12 months (extendable once by 6 months). Modifications need a public hearing; appeals go per Title 2, Ch. 2.100.
  • Mixed-Use Overlay (MUOZ) (Ch. 17.49). Applied narrowly to lots at 7020–7030 Atlantic Ave.; it permits neighborhood-serving commercial on the first floor and multiple-family units above (up to 30 du/ac), subject to administrative site plan review. Development standards include: minimum lot area 7,200 sf; minimum widths 60/65 ft (interior/corner); lot area per unit 1,452 sf; maximum height 4 stories/45 ft; setbacks 15 ft front, 5/10/15 ft sides (interior/street/corner), and 10 ft rear.

Building permits & review

• Zoning clearance vs. site plan review. A zoning clearance is ministerial and confirms compliance with the zone and applicable standards; it’s used for defined scopes, including all ADUs/JADUs, certain small residential additions, and interior tenant improvements.
• Site plan review is discretionary and required wherever the code says so; smaller projects can be approved by the Community Development Director, while larger or referred cases go to the Planning Commission with notice and findings on plan consistency, architecture, and landscaping. Appeals are per Title 2, Ch. 2.100.
• Ties to building permits. If a site plan or zoning clearance is required, no building permit may issue (or remain in effect) until that approval is in place.
• Zone- and district-specific triggers. For example, site plan review is required before building permits in C-3R and M.
• Building code. Construction must also comply with the California Building Standards Code adopted locally; Title 17 references building code parameters for reconstruction thresholds and similar matters.

State housing law in Bell

• ADUs and JADUs. Bell implements state ADU law through Chapter 17.54, which aligns with Gov. Code §§65852.2 and 65852.22. The city processes ADUs/JADUs ministerially via zoning clearance; local standards include design-match requirements, separation/open-space rules, and an explicit allowance that if local coverage/size rules would otherwise block an 800 sf ADU, the 800 sf ADU must still be allowed if other standards are met. ADU parking rules are contained in §17.54.070.
  • State overlay: current law requires jurisdictions to accommodate at least an 800 sf ADU with 4 ft side/rear setbacks and limits detached ADU heights (generally 16–18 ft depending on transit and context), and restricts when parking can be required; Bell’s Chapter 17.54 operates within these statewide limits. See the overview of California ADU law for details.
• SB 9 (two-unit projects and urban lot splits) and density bonus. A local SB 9 or density bonus ordinance was not identified in the retrieved materials; the city must still process qualifying projects under state law. Confirm current local procedures with Planning; see California housing laws. Not found in retrieved materials.
• Rent regulations. Title 17 does not address rent control or just-cause eviction. Check the municipal code outside Title 17 and state law for applicability. Not found in retrieved materials.
• Nonconforming housing status. The code clarifies that uses granted by prior variances or CUPs continue subject to §17.96.170–.180, and violations of prior zoning do not gain legal nonconforming status by adoption of the current code. See Bell Nonconforming Uses.
