Wall in the foyer that constantly need to be straighten.Do you think I have major problems
Arising?What should I do?The houses built in this almost new subdivision were developed
On an old land field...

I think you need to bring out a real contraction contractor to inspect it. There is always a little settling but these seems extreme.

Also missing the term old land field, what type of field ?

Many states have laws requiring that a builder provides a warranty when selling new construction. The structural portion of the warranty is usually for 10 years. Did you buy directly from the builder? Did you receive a warranty? If so then you should contact the warranty company to have them come out and inspect rather than spending money on a contractor.

If you didn't receive this type of warranty when you purchased then you should definitely have the house examined by an expert, preferably an engineer.

The landfill I mentioned was disposal of trash approximately 15-20 years ago.

... an old land field....

landfill

Ah.

It's spelled "landfill", actually. As in "fill" the land with junk and trash.

I don't know if it affects anyone's liability. The builder, as well as the subdivision developer, should have anticipated settling, knowing the history of the land. But I don't think this fact would expand the warranty.
