I am 8 years in a Genesee/Lennar home.
First the plumbing lines were not angled right so the draining was bad. Had to get an independent plumber to tell Lennar what the problem was. Then noticed that the interior paint was sticky. I was told that would not be a problem, I had to let the paint dry. Yeah right...
And now, 8 years later, I am in the midst of getting a deck majorly repaired because of water damage. Yes, water damage in North Denver, Colorado.
I've been continually frustrated with the "cheap" material including the paint that was used by Genesee/Lennar Homes. But what is most scary, is to use below spec/below grade material on a deck that is now literally unsafe to walk on.
I don't know if there is recourse in regards to this but I am going to do some research to find out.
If you build or purchase a Lennar (or previous built by Genesee) home, please make sure you grab a very very good inspector before purchase or closing on a newly built home. This will save you a lot of grief.
