Your legal address appears on tax returns, on the USPS, on your driver's license and on your voter registration card. Simply put, a primary residence is where a person or family spends most of their time. Establishing a property as your primary residence means that you should spend most of your personal time there, whether the home is owned by you or is leased. Owning a property alone does not make it a primary residence.
In a nutshell, a primary residence is the primary home in which a person lives. It can be a house, apartment, trailer or houseboat where a person, couple or family lives all or most of the year. It's also the address that appears on a person's driver's license, car registration, and voter registration card. And, in general, a person's primary residence is the house closest to a person's employer.
