Foundation Walls

[Dublin ohio]

Have appraised numerous properties with a concrete slab for foundation. Have always put poured concrete for foundation walls. The only other thing you could say would be none going by the technical definition of wall. Have never been called out in 23 years for putting poured concrete for basement wall material for slab foundation. Makes sense within the context of that section which asks for materials and condition

In areas with a frost line the foundation must extend down to the frost line (most county codes). A footer is dug down to about 3 feet and poured 1 foot deep by 18" wide. On top of that is a concrete block foundation wall (Stem wall) up to or above the finished grade. The interior is filled with sand or pea gravel and then the concrete pad is placed on top of that. So, most slab floors have a concrete block stem wall down to the footing. On very wide pours there may be extra stem walls or piers for the middle of the concrete pad. In some areas a flooting pad is allowed but most are required to go deep enough on the edges to keep frost and rodents from infiltrating.

Do slabs in your area require that the perimeter turn down deeper than the slab thickness?

Here is what the FHA has to say about filling out that section of the URAR:

Appraisal Report and Data Delivery Guide, page 20:

Foundation Walls: Enter the material type: poured concrete, block, brick stone, treated wood, etc., and rate the observed condition.

99.9 % of the homes in Phoenix have no basements or crawl spaces. Foundation = Concrete Slab, Foundation walls = Concrete/Avg

This is the typical foundation

A slab is a foundation.

That would be a no. Before a slab is poured, reinforced concrete footers are poured at places where major weight bearing walls are located. Concrete block is then laid on the footers and filled with concrete to bring the slab to grade when poured. Even a monolithic slab will have footers dug. The only difference between a foundation in Florida, California or Upstate New York is the depth they have to be dug to get below the frost line. In the southern states its zero so footers are typically 18" deep. In Upstate New York they have to be 8-10 feet. As long as you're digging down that far, you might as well haul away all the dirt and make a basement.

Puerto Rico is in the tropics so there is no frost line
The construction you described is typical in the island
So if the slab and footers are considered the foundation
Where are the foundation walls?
I believe the proper answer is "None"
What you have is then the "Exterior walls"
But those are answered as a different item

 

[Carlos Danger]

I was considering the footers and slab as one piece. Surely you are not saying a house on a slab has no foundation.

Of course not

What I do on my reports is put a check mark on "Concrete Slab'"
and "None" or "N/A" in "Foundation Walls" as there is no basement nor walls below grade

BTW I also consider the footers and slab as one piece
