Requires exterior cages for air conditioners

This bill requires exterior cages for air conditioners installed in apartment buildings and other multiple-dwelling properties. It directly affects building owners and managers who install AC units on exterior walls, mandating protective cages unless the unit is fully inside a dwelling unit or already secured by a window sleeve. The law exempts existing installations meeting those criteria and takes effect 90 days after enactment. It focuses solely on physical installation standards, with no mention of enforcement details or cost impacts.
