The New York State Liquor Authority regulates establishments that want to make, sell and/or store alcohol for consumption on- or off-premises. There are many rules about where the premises can be, who can have an interest in the licensed premises and how the business can operate. The exception to NYSLA regulation is for on-premises consumption where the establishment has a maximum occupancy of less than 20 persons. In this instance, a license for retail on-premises consumption is not required. The premises must be able to prove the officially established maximum occupancy with a Maximum Occupancy Certificate issued by the local municipality.
