Buying Home with Un Permitted ADU

[Kristjan Schweizer]

Hey there!

I am considering purchasing a home that has a fully built ADU. I am considering the risk and was hoping for some input. The ADU was built by a licensed and bonded contractor that didn't get the permits due to time constraints. I plan on living in the home and renting out the ADU. I am not sure I even need to permit it but curious of risks I am taking on and if anyone here has experience with this type of situation.
