With our tool you have full control over what should be included or excluded from the GLA sketch thanks to space properties. The GLA calculation logic relies on them, as to be included in the GLA a space needs to be:

  • Heated

  • Finished

  • Enclosed

  • Contiguous

  • Permitted

  • Space ceiling height is less than 213 cm (7 ft.)

How to

These options can be accessed through the Quick Edit tool.
Simply click on the label of a space to display its options. You can now check/uncheck the properties and change the ceiling in order to include or exclude a space from the GLA calculation.

Properties details

Heated: Area is heated.

Finished: The walls, floors, and ceiling are all finished to the same level as the rest of the house, with electricity. If a brick exterior wall is present, or baseboards can be seen (except in renovation) the area would NOT be considered finished.

Enclosed: The area should have no areas open to the outside (except for doors/windows). If there is no ceiling or a wall is missing (to the outside, not the inside of another room), then the area would not be considered enclosed.

Contiguous: The area can be accessed from the primary living area. If you have to leave the main house to go outside, through a garage or porch, or other non-living areas, it would not be considered contiguous. This doesn’t apply to basements, where finished vs unfinished is often relayed as a percent of the area that is finished, and is non-GLA.

Permitted: Any area that has been given legal allowance to be built. Generally, most rooms will be permitted. If an area is or is not permitted should generally be identified by an appraiser.

Addition: An area added to a structure that was not part of the original building. These can be complete rooms or extensions to existing rooms.

Conversion: A part or entirety of a room or building that has been converted from an unfinished area to a finished area. Most often occurs with garages, but can also be seen with other rooms, such as enclosed porches.
