bought a house but found the construction permit is missing

[Yong Lai]

Hi all,

I bought a house in Dec 2021. The house is a new build and close to Dallas downtown. Now I am trying to install solar panels on the roof and find out that the construction permit for the house wasn't completed. The city of Dallas notified me that the builder/seller pulled the construction permit in July 2021 but never completed it. Now the permit expired due to inactivity and based on their record, there is basically nothing built on the lot where my house sits. I contacted the seller but he simple doesn't respond. I contacted this seller last year regarding the house quality issue and he simply denied any responsibility although the house was still under one year warranty. What should I do in this situation? Should I go to the lawsuit route? 

thanks,

Yong
