Requirements & Zoning

Long Beach regulates ADUs through zoning and the building code; key topics include permitted locations, size limits, setback rules, lot coverage, and parking reductions where state law applies. Review the municipal code for zoning definitions and any adopted local modifications before preparing plans.[2]

  • Determine zoning designation and permitted ADU types (attached, detached, internal).
  • Confirm maximum ADU size and height limits for your lot.
  • Check parking requirements and possible state-law suspensions.
  • Prepare site plans, floor plans, elevations, and utility connections for review.

Specific fine amounts for ADU violations are not provided on the cited municipal pages; where fine schedules or civil penalties exist they appear in enforcement or code sections and should be confirmed with the department.
