Question:   What is a "principal residence?"  

Answer: The tax credit for energy efficiency is available for improvements made to a home that you own and use as your "principal residence." This is the home where you live most of the time. A temporary absence due to special circumstances, such as illness, education, business, military service, or vacation will not change your principal residence.
The home must be in the United States. It can include a house, houseboat, mobile home, cooperative apartment, condominium, and a manufactured home.
