A basement garage is a garage that is partially or mostly below grade in single-family residences, town houses and duplexes:
Enter a basement garage as follows:
Enter the entire basement area (including the area of the garage) for component 801 (Total Basement Area) to include the cost for excavation, floor structure, supporting columns and basement walls.
Use this component and/or components 805 (Basement Garage, Single) and 807 (asement Garage, Triple) ) to add the additional costs associated with the garage, including garage door and finishes on common interior walls and ceilings for a basement garage. Enter the number of each of these basement garages in the residence.
Instead of these components, you can add the cost of the basement garage finish by entering the size of the basement garage in square feet for component 804 (Basement Garage Finish Area).
