I am looking to by a home with crawl space. The crawl space is a dirt floor and has 4' clearence at the back end of the house and 5' clearence at the front. It is about 20' by 17'. The space is very dry and there is no ledge that may restrict my digging down a few feet.
The problem I have is that there is no footing. This will make it easier for me to work around but I have a great concern about the strength of the structure if I start digging. The cement walls as they sit now are solid with two minor hairline cracks.
I plan on having a professional do the work but would like to know what options I have and how this would be handled.
