Your property owner association bylaws say you can't put up a "for sale" or "for rent" sign... nor can you display an American flag on your balcony.
Are these regulations legal... and will they hold up in court? Lynette Reagan, a board member of Rockrimmon Condominiums says she learned the answer to both questions is no.
It's the reason she and other board members joined the group called CAI, Community Associations Institute.
She says residents are glad they did.
Lynette says, "I think they appreciate the idea we're bringing in very definite answers. We know where we can go to check on things. We know materials that CAI offers, so we use those."
One measure impacting residents and property owner associations alike is known as Senate Bill 100, a measure which became law in Colorado in 2006.
It spells out new rules on everything from landscaping and parking to meetings held by board members of POAs.
And while residents don't stay current on all this stuff CAI does.
According to Eric Phillips with CAI, "Our main objective is to educate members, home owners, the community on HOAs... rules, regulations, legislation."
CAI which has been around ten years... also gives advice on budget and financial issues. It says one out of every six Americans is governed by some kind of homeowner association.
