Overview: ADUs, Elevators and Lead Safety

In Hesperia, ADUs are regulated through the city building and planning permit system and by the adopted California building and health standards. Elevator installation in multi‑unit ADUs, or when a lift is used to meet accessibility or habitable‑space rules, may trigger additional plan review for structural, mechanical and accessibility compliance. Lead‑safety obligations apply to renovation, repair and painting activities in pre‑1978 buildings and to contractors performing work that disturbs painted surfaces.

For permit applications and department contacts, consult the City of Hesperia Building Safety and permits page City of Hesperia Building Safety[1]. The Hesperia Municipal Code contains local enforcement provisions and adopted codes Hesperia Municipal Code[2]. Federal lead renovation rules are administered by the U.S. EPA EPA RRP[3].
