Here is the regulation from the guide.

Hunting, shooting or carrying of loaded firearms within 500 feet of any building occupied by people or domestic animals or used for storage of flammable material, or within 250 feet of such buildings when waterfowl hunting in tidal areas from land shooting positions or from floating blinds anchored adjacent to land or from rock positions, is prohibited, unless written permission from lesser distances is obtained from the owner and carried. Landowners, their spouses and lineal descendants are exempt from this restriction, providing any building involved is their own.
