- ALQs are limited in the size of livable square footage to a maximum of 50% of the livable square footage of the principal dwelling or 1,000 square feet, whichever is less.
Livable square footage is the sum of the area contained within a principal dwelling measured from the inside wall surfaces, including finished basements but excluding garages, carports, porches, utility rooms, stairways, sheds, storage rooms, balconies, and patios. More generally, it is the area that is heated or cooled.
