ADU Rules
Long Beach Zoning Ordinance defines a garage apartment as a dwelling unit erected above a private garage, regulated as an accessory use subordinate to the principal dwelling. Comprehensive Land Use Ordinance #676 (effective Aug 11, 2025) is the controlling instrument; it replaces the 2013 Unified Land Use Ordinance #598. Accessory structures must be on the same zoning lot as the principal building and be subordinate in area, extent and purpose. Mississippi has no statewide ADU preemption, so Long Beach permitting standards (setbacks, height, parking, owner-occupancy) govern.
