Board sent letter Addendum to Rules and Regulations: Unit Remodeling Rules" for windows to be changedand given owners 15 days to get permits

An owner is running some type of retail/showroom out of their condo.  There are constantly people buzzing into the building and walking around the halls.  Our bylaws do not say one can not run a business. 

Can you help us understand what our condo association's CC&R is saying?

I am a mortgage broker and I can not find a contact to get the condo docs and bylaws for a borrower.  Where can I get this HOA information?

How does condo association enforce the rules and regulations from the bylaws?

They remove the stop sign and the Property Manager confirms it was removed and then then put the sign right back.
