Bell — Land Use

Land Use under the Bell local zoning and planning code, with the controlling citations.

Ask AI what you can build See coverage

Quick answer

Bell assigns uses by zone (R‑1 through M), with overlays never expanding allowed uses beyond the underlying zone (§ 17.48.040, § 17.48.090). Homes in R‑1/R‑2 need a 25 ft front setback and cap at 30 ft/2 stories (§ 17.16.040; § 17.20.040). ADUs are allowed citywide with 4 ft side/rear setbacks and 16 ft max height (§ 17.54.050). Alcohol sales need a CUP; gas-station/convenience-store beer/wine is limited to 10 a.m.–10 p.m. with other conditions (§ 17.96.030).

Overview

Bell regulates land use through Title 17 Zoning of the municipal code, which assigns every parcel to one of eight base zones and, in some cases, an overlay. What you can do on a lot depends first on its base zoning, and then on any overlays and citywide conditional-use limits. Use-specific standards (like alcohol sales) apply citywide and can require discretionary approvals. For a high-level map of how these pieces fit, see the Bell zoning & planning overview.

In Bell’s overlay areas, a use is allowed only if it’s permitted by the underlying zone, and no permits are issued in an overlay until a precise development plan is approved (§ 17.48.040, § 17.48.060, § 17.48.090).

How Bell organizes land uses (zones)

Bell establishes these base zones, from most to least restrictive: R-1, R-2, R-3, C-3R, C-3, C-M, M, and T (§ 17.12.010). Your parcel’s “underlying zone classification” is what appears on the city’s official zoning map (§ 17.08.716). See Bell Zoning for map access and district boundaries.

Citywide conditional uses (CUPs) you should know

Certain uses are only allowed citywide if you obtain a conditional use permit (CUP). These include airports/heliports and several types of alcoholic-beverage sales with specific operating limits (§ 17.96.030). When you apply for a CUP (or variance), you must submit a full development plan with site boundaries, proposed buildings/uses, parking, open space, elevations, landscape, and a schedule (§ 17.96.080). The City may attach conditions to prevent impacts like noise, light, odor, and traffic (§ 17.96.090). If you’re seeking relief, also review Bell Variances and Exceptions.

Key CUP triggers and conditions (§ 17.96.030):

  • Airports and heliports: CUP required in all zones.
  • Alcohol at restaurants: CUP with annual review; alcohol sales must be ≤ 20% of gross food+alcohol sales; annual financials due by March 1; audits and security can be required; other conditions possible (§ 17.96.030(2)(a)).
  • Gas stations selling beer/wine for off-site consumption: CUP with annual review; sales limited to 10 a.m.–10 p.m.; no less than six-packs; no malt liquor; trained seller; at least two attendants during sales; clear plastic bagging; security measures may be required (§ 17.96.030(2)(b)).
  • “Beer and wine convenience store” (< 23,000 sq ft) for off-site consumption: must be ≥ 500 linear ft from schools, parks, churches, and from another such use; CUP with annual review; alcohol ≤ 25% of gross sales; 10 a.m.–10 p.m. hours; six-pack minimum; no malt liquor; audits and other conditions may apply (§ 17.96.030(2)(c)).

Overlay districts that affect land use

  • Overlay Zone (Chapter 17.48). Overlays provide flexible planning for commercial/industrial projects but cannot authorize uses beyond what the underlying zone permits (§ 17.48.040, § 17.48.090). A precise plan of development is required before any permit or use may commence in an overlay (§ 17.48.060). See Bell Overlay Districts.
  • Mixed-Use Overlay (Chapter 17.49). Where applied, principal use is limited to multiple-family dwelling units above the first floor, up to 30 du/acre (§ 17.49.050(A)). Accessory uses allowed include ADUs (Chapter 17.54), limited home occupations, and domestic animals per BMC 6.04.010, with conditions (§ 17.49.050(B)). Each unit must have a private balcony of ≥ 150 sq ft (§ 17.49.050(C)).

Related screening and frontage landscaping are enforced; see Bell Landscaping and Screening.

Nonconforming and prior entitlements

  • As long as a nonconforming use/building exists, no new use/building may be added except as expressly allowed (§ 17.100.030). See Bell Nonconforming Uses.
  • Previously granted variances/CUPs remain in effect if their conditions are met, and such uses are not deemed nonconforming solely due to that status (§ 17.04.060).

Practical notes for commercial corridors

  • All uses in any C zone must operate indoors unless the Planning Commission determines the use is customarily conducted outdoors; outdoor sales are limited to retail goods sold on-site; outdoor storage areas must be screened and paved; hazardous-material users must have interceptors/clarifiers and follow applicable disposal laws (§ 17.36.030). If exterior storefront security measures are proposed, check the C-3/C-3R rules (§ 17.32.040(I), § 17.28.040(I)). Coordinate early with Bell Design Review for facade/security treatments and Bell Signage.

Checklist

  • Confirm the parcel’s base zoning and any overlays on the city’s official zoning map (underlying zone governs uses) (§ 17.12.010; § 17.08.716).
  • Identify whether your proposed activity is a listed citywide conditional use (airports/heliports; restaurant alcohol; gas-station or convenience-store beer/wine) and prepare a CUP with a full development plan (§ 17.96.030; § 17.96.080).
  • For any overlay parcel, prepare and obtain approval of a precise plan of development before any permit or use start (§ 17.48.060).
  • If in the Mixed-Use Overlay, confirm your residential program is above the first floor and ≤ 30 du/acre, and provide 150 sq ft balconies (§ 17.49.050).
  • Verify setbacks, height, and adjacency walls for your zone; apply landscaped frontages in C/C-M/C-3R as required (§ 17.28.040; § 17.32.040; § 17.36.040; § 17.40.040).
  • Confirm parking location compliance; in C/M zones, off-site options are limited and must be within 400 ft and legally guaranteed (§ 17.76.080); see Bell Parking.
  • For ADUs/JADUs, apply citywide standards (e.g., 4-ft side/rear, 16-ft height, design match), and the ban on above-garage ADUs in R-1 (§ 17.54.050; § 17.54.060).
  • If relying on a prior CUP/variance, confirm it remains in good standing (§ 17.04.060); if a site is nonconforming, verify limitations before changing/adding uses (§ 17.100.030).

Risks & Ambiguities

Issue Why it matters What to verify
Missing permitted-use lists by district You need to know if your use is allowed by right vs. CUP Principal permitted uses for each zone (R-1, R-2, R-3, C-3R, C-3, C-M, M, T). Not found in source materials. Verify with the jurisdiction.

Mixed-Use Overlay boundaries Determines if residential-over-commercial is allowed Whether your parcel is within the Mixed-Use Overlay and any additional criteria beyond § 17.49.050. Verify with the jurisdiction.
Alcohol CUP renewal and audit conditions Affects operating costs and compliance Annual review, financial submittals, potential police/security conditions for alcohol-related CUPs (§ 17.96.030).
500-ft separation for beer/wine convenience stores Site selection feasibility Confirm measurement method (“linear feet”), applicability to existing vs. proposed sensitive uses (§ 17.96.030(2)(c)(ii)).
Off-site parking substitution limits May constrain tenant mix and floor area Whether off-site parking within 400 ft is feasible and legally secured; ensure 80% on-site minimum is met (§ 17.76.080).
Overlay plan requirements Can add time and design commitments Required submittals/maintenance obligations for overlay plans (§ 17.48.060; § 17.48.030).

Plain-English Summary

Bell divides land into eight zones and then layers on special rules like conditional-use permits for alcohol and overlays for project-specific planning. Residential areas generally need 25-foot front setbacks and cap out at two stories, while commercial yards are often 10 feet and industrial has none unless driveways enter the building. ADUs are broadly allowed with 4-foot side/rear setbacks and 16-foot height, but you can’t put an over-garage ADU in R‑1. When in doubt, check if your use needs a CUP and whether an overlay plan is required.

Frequently asked questions

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

R-1 is intended for single-family residential. The code provides dimensional standards (e.g., front setback 25 ft; 30-ft/2-story height cap) and allows ADUs subject to Chapter 17.54, but a detailed list of principal permitted uses was not provided in the source materials (§ 17.16.010; § 17.16.040; § 17.54.050). Verify permitted uses with the City.

Can a Bell gas station sell beer and wine?

Yes, but only with a CUP that is reviewed at least yearly and subject to strict conditions: sales limited to 10 a.m.–10 p.m., no less than six-packs, no malt liquor, staff training, two attendants during sales, and clear-bagging of alcohol, among others (§ 17.96.030(2)(b)).

What are the front setback requirements for homes in Bell?

In both R-1 and R-2, front yards must be at least 25 feet deep or the average of the block’s front setbacks, whichever is less (§ 17.16.040(C)(1); § 17.20.040(B)(1)). Rear yards are 10 ft; side yards are typically 5 ft, with 10 ft on the street side of corners (§ 17.16.040(C); § 17.20.040(B)).

Are mixed-use residential units over shops allowed in Bell?

Where the Mixed-Use Overlay applies, multiple-family dwelling units are allowed above the first floor, up to 30 dwelling units per acre, with each unit having a 150-sq-ft balcony (§ 17.49.050(A), (C)). Uses must still be consistent with the underlying zone (§ 17.48.040; § 17.48.090). Confirm overlay boundaries with the City.

Do restaurants need a CUP to serve alcohol in Bell?

Yes. Restaurants otherwise permitted in their zone may serve alcohol for on-premises consumption only with a CUP, which is reviewed annually and limits alcohol sales to 20% of total food+alcohol sales, with required financial reporting and potential security conditions (§ 17.96.030(2)(a)).

Where can commercial projects provide off-site parking?

In C and M zones, required parking must be on the same lot, but the City may approve a substitute lot within 400 feet walking distance if at least 80% of spaces (and no fewer than 10) stay on the principal lot and the off-site parking is legally guaranteed (§ 17.76.080).

Can I put an ADU over a garage in Bell?

Yes in R-2, R-3, and C-3R, where an ADU may be built on top of a one-story detached garage or other detached structure; not allowed in R-1 (§ 17.54.050(E) n.4). Citywide ADU setbacks and height still apply (4-ft side/rear; 16-ft height) (§ 17.54.050(E)).

How tall can industrial or commercial buildings be?

Generally up to 70 ft in C-3, C-3R, and M, and up to 150 ft in C-M, but if the site is within 50 ft of an R-1 lot line, the height must match the R-1 maximum in that band (§ 17.28.040(C)(1); § 17.32.040(C)(1); § 17.36.040(C)(1); § 17.40.040(C)(1)).

What limits apply to outdoor sales and storage in commercial zones?

All C-zone uses must occur indoors unless customarily outdoors as determined by the Planning Commission; outdoor sales are limited to on-site retail goods and storage areas must be fully screened and paved. Hazardous-material users must install interceptors/clarifiers and comply with disposal laws (§ 17.36.030).

Do nonconforming uses block new projects on the same lot?

Yes. As long as a nonconforming use/building exists, you generally may not establish a new use/building except as expressly allowed (§ 17.100.030). Prior CUPs/variances remain valid if conditions are met (§ 17.04.060). See Bell Nonconforming Uses.
