How Big is My House Really?

Q: I measured the square footage of the home I was buying, and it was totally different from what was advertised. What gives?

A: Measuring a home's square footage is not as simple as it sounds. There are a number of rules about which space can be counted and which can't. The basic rules state that, in order to be included in the square footage, the space must be (1.) intended for human occupancy, (2.) heated by a permanent heating system, (3.) have direct access to another living area, and (4.) it must have finished floors, walls, and ceilings. But there are special cases. Stairways, for example can be tricky. Bay windows, open foyers and rooms with sloped ceilings can be challenging, too. Additions done without a building permit may not be able to qualify at all. Because there are so many different rules, buyers, sellers and even real estate agents should not attempt to measure the home. This job is best left to a licensed appraiser.
