Hospital helipads in LA County need a building permit under California Building Code §1503.3 plus LACOFD Title 32 fire approval. Medevac flights enjoy emergency exemptions from §12.08.330 noise rules, but routine training flights must minimize residential disturbance.
Hospital rooftop helistops in LA County clear three layers. Building approval comes through LA County DPW Building & Safety enforcing California Building Code §1503.3 (load, FATO/TLOF dimensions, lighting, and edge protection). Fire and life-safety review is conducted by LACOFD under Title 32 (LA County Fire Code), including foam suppression for elevated decks. Operationally, FAA Form 7480-1 airspace approval is mandatory. Once permitted, medevac flights are exempt from county noise ordinance §12.08.330 under the emergency-vehicle clause. However, hospitals running training, transfer, or non-emergency flights must follow voluntary noise abatement procedures including avoiding 10pm-6am hours when feasible. LA County hospitals like Harbor-UCLA, MLK, and Olive View are major operators.
Operating without LACOFD or Building & Safety approval is a misdemeanor under Title 32 with daily fines up to $1,000 plus stop-use orders. FAA can revoke airspace approval. Routine overnight flights may trigger §12.08.330 nuisance complaints.
