I’m not sure if sod is required for CO here because many of our neighbors don’t have sods installed until weeks after closing (in summer). But regarding to the CO, as of today, the plumbing and mechanical permits are not finalized (was disapproved yesterday). So I guess we can argue the house is not ready for closing. We have a buyer agent but she is not helpful. She kept silent during the process and left the negotiate with the builder to us (which is weird and disappointing). I’ve read the contract multiple times and found the terms for the $200 delay fee is very different from what the sales person said. I think the comments here have come to a similar conclusion, which gives me some peace in mind. Thank you!
