Be aware of anti-discrimination laws and how to avoid running afoul of Fair Housing requirements.Establish a good rental agreement that is compliant with the laws for your jurisdiction.

I would want to see his paperwork to be sure he is compliant with all the laws.

Welcome back to high school math haha.Additionally, the parties can see significant consequences if they are not compliant with the rules which can also void your agreement.

We cleared all permit requirements and were marked compliant.

I'm simplifying, but did you know the baby could ingest lead from dirt in some completely random place and you would still be liable because they don't have to prove it came from your house if you are not compliant--and in this case they have documentation that proves its in your house.

Added attached garage, made all bedrooms compliant, increased bathroom size, added laundry room, reconfigured kitchen layout
