San Bernardino Mixed-Use Density Rules

Land Use and Zoning California 4 Minutes Read · published February 10, 2026 Flag of California

San Bernardino, California regulates how many housing and commercial units are allowed in mixed-use zones through its zoning rules, development standards, and application processes. This article summarizes where density limits typically appear in city regulations, how developers and property owners request exceptions or variances, and practical steps for compliance and appeals. Use the official municipal code and the Planning Division guidance when preparing site plans or conditional use permits to confirm exact numeric limits and any applicable overlays.[1][2]

How density is set in mixed-use zones

Allowed density in mixed-use districts is generally defined by the zoning designation, development standards (floor area ratio, lot coverage), and any applicable overlay or specific plan. The municipal code may list permitted uses, minimum lot sizes, and sometimes maximum dwelling units per acre, but many projects are also governed by General Plan land-use designations and special plans.

Check the zoning designation and any applicable specific plan early in project planning.

Typical standards and measurements

  • Density often expressed as units per acre or units per lot; sometimes FAR is used instead of unit counts.
  • Setbacks, height limits, and parking minimums affect achievable density.
  • Density bonuses or incentives (affordable housing, transit-oriented development) may increase allowable units where the municipal code or state law applies.

Planning review and approvals

Projects in mixed-use zones typically require planning staff review and one or more public hearings for conditional use permits, site plan review, or variances. Engage the Planning Division early for pre-application guidance and to identify discretionary steps.

Penalties & Enforcement

Enforcement of zoning and density rules is handled by the city through code enforcement, building and safety, and the Planning Division. Specific monetary fines, escalation steps, and non-monetary remedies are controlled by the municipal code and administrative enforcement policies.

  • Enforcer: Planning Division, Building & Safety, and Code Enforcement departments; contact via official planning or code pages.[2]
  • Fine amounts: not specified on the cited page.
  • Escalation: first/repeat/continuing offence procedures and amounts are not specified on the cited page.
  • Non-monetary sanctions: stop-work orders, administrative abatement, notices to appear, civil injunctions, or referral to the city attorney for prosecution.
  • Inspections and complaint pathways: file a complaint with Code Enforcement or submit a planning inquiry to the Planning Division.
  • Appeals and review: appeals of planning decisions are heard by the Planning Commission or City Council per municipal procedures; time limits for filing appeals are not specified on the cited page.
If a specific fine or deadline is required for your case, request the enforcement guideline from the enforcing department.

Applications & Forms

The city publishes application forms for entitlements such as conditional use permits, variances, and site plan reviews. The exact form names, numbers, fees, and submittal methods are provided by the Planning Division or Permit Center; if a specific form or fee is not on the cited page, it is not specified on the cited page.[2]

Common violations and practical penalties

  • Building more units than allowed without proper permits — typically subject to stop-work orders and potential fines.
  • Failure to obtain conditional use permit or variance — administrative enforcement and possible reversal of permits.
  • Noncompliance with density bonus conditions (affordability requirements) — loss of bonus and enforcement actions.
Document compliance steps and approvals before marketing or occupying units.

How-To

  1. Confirm the property's zoning and any specific plan or overlay that affects density.
  2. Request a pre-application meeting with the Planning Division to review density calculations and required entitlements.
  3. Prepare and submit complete application forms, site plans, and any environmental documents to the Permit Center or Planning Division.
  4. Attend public hearings as scheduled and respond to conditions requested by staff or commissioners.
  5. If issued a violation, follow correction orders promptly, pay assessed fines if any, and use the appeal process if appropriate.
