Home foundation problems.
I recently purchased a used home in August, 2008. The home was built in 2004. When I purchased the home I failed to notice any drainage problems. I did have a home inspector evaluate the house and he did notice some water pooling underneath the crawl space. The home owners at that time installed a sub-pump at that location. Thinking this would fix the problem. Now I have water pooling up around my foundation due to the site grading. I am an engineer and I looked up the building code. At the time the house was built the counties building code followed the International Residential Code (IRC). In the ''Foundation'' section, it states that the lot should slope away from the home with a minimum 2% grade extended to 10 feet around the home. The current grade slopes directly toward my home. My question is, if the builder did not meet IRC code, are they responsible for re-grading the lot? Now my home has shifted and I have cracks in the walls/door misalignment. Thank you in advance for your help.
