House hacking Condo: Can you sleep in the living room & rent out the other bedrooms? 

I am planning to house hack a 2 bedroom 2 bath (1000 sqft) condo in Houston, TX. I am wondering if I am able to sleep in the living room and rent out all of the bedrooms. Is this legal and should it be accepted by the HOA?

Can I make any additions to the inside of the condo like another bedroom? I may plan to use wood studs to make another bedroom in the living room area (either a temporary one or permanent). Is this legal and should it be accepted by the HOA?

Thank you.
