Read your HOA bylaws re: finish work. Typically, the HOA shouldn't give a hoot about work inside of your condo so long as it doesn't have the potential to interfere. i.e. if you're doing some bathroom maintenance then they'll want to make sure your contractor is licensed and bonded and that they are aware of when they're coming.
