Lancaster, CA Trash & Recycling: Dumpster Rules (2026)

Lancaster's C-zone design requirements set a specific formula for commercial trash and recycling storage: 20 square feet of storage area for every 1,000 square feet, or portion thereof, of net floor area in the facility, with a floor for the required area, but never less than 6 feet wide and 18 feet long as an exterior dimension. The storage area must include separate containers for waste and for recyclable materials, and each container has to be clearly marked or color coded to show which is which, reflecting the state source-separation mandate.

Physically, the enclosure must be walled on three sides by masonry or concrete construction at least 5 feet high, fitted with a sight-obscuring gate made of noncombustible material; chain link fitted with slats does not satisfy that gate requirement. The enclosure floor must be concrete, and the walls need a protective concrete curb or conventional wheel stops so dumpsters being wheeled in and out do not damage the masonry. Placement is restricted too: the storage area cannot sit in a spot that is openly exposed to a fronting street or to a neighboring residential area, a siting rule the broader design section reinforces by directing that trash enclosures generally be located away from primary building entrances, drives and streets and be designed with a non-combustible overhanging trellis or roof cover, and separated from adjacent parking by a 6-foot-wide planter.

120, so a property owner adding or relocating a dumpster enclosure after initial construction needs the director's sign-off that the revised layout still meets these dimensional and screening standards.
