Unfortunately, as Deborah confirmed, the GLA of a home can vary. It is a subjective number due to the factors pointed out by my fellow colleagues. When in doubt, call the listing agent to confirm what is or isn't included in the GLA calculation. Do not use this stated figure alone when researching homes to purchase. Your best bet is a local REALTOR who serves the specific area where you are looking. Please consider finding a buyer's agent to assist you in your search. He/she can prove an invaluable source of information and will most likely save you a bit of time and money. Best of luck and happy hunting!
In my market, what is considered true GLA, is anything considered to be habitable space (finished and heated) A basementsâ€™ space would not be incorporated into the GLA unless it is above grade and there is an egress. Iâ€™m in MA, so air conditioning is not a requirement. â€œPublished GLAâ€ in my area is space that the town has record of, so if there were not building permits pulled for particular areas of a home that have been finished, such as an attic or a basement that is above grade with an egress then the â€œPublished GLAâ€ would not reflect the additional living area.
