Due to a recent change in code and inconsistent filings, "H-2" can mean one of three things: "Making, processing, generating or storing hazardous materials that present a sudden-burning hazard or a hazard from chemical burning" or "Day care facilities, occupied by persons of any age who receive custodial care (without overnight) by individuals other than parents, guardians or relatives in a place other than at home" or "Medical, surgical or custodial care on a 24-hour basis of more than three persons who are not capable of self-preservation."
