Help for Question 4

What type of foundation does your house have?

If different parts of your home have different foundation types, select the type that underlies the largest floor area. If your home is a split-level or tri-level, select the type for the part of your home that is at ground level.

Slab-on-Grade

This is a poured concrete foundation that rests on the soil surface

Unconditioned Basement

Unconditioned basements do not have heating or cooling, and are not used as living space.

Conditioned Basements

Conditioned basements have heating or cooling, the walls are generally finished, and the space is part of the living space of the house.

Unvented Crawlspace

The house is on a raised foundation, with 2 to 3 feet of airspace under the floor. Unvented crawlspaces do not have open vents to the outside, and are typically warmer than vented crawlspaces.

Vented Crawlspace

The house is on a raised foundation, with 2 to 3 feet of airspace under the floor. Vented crawlspaces have open vents to the outside, so the air under the house is close to the same temperature as outside air.
