I've been asked a lot of questions about the upcoming political elections, and the main concern is whether or not Association members may place advertising signs in their yards.
No signs may be placed in common areas, only in private or limited common areas.
The Colorado Common Interest Ownership Act reserves the free speech right of Association Members. Signs are restricted in size (24" x 24" or less), to one for each ballot issue (or candidate), and most importantly: not placed before 45 days before the election and not to exceed 7 days after the lection.
I have linked you to a more elaborate explanation with this website. Please note that you DO have rights to display political signs! The writer of the attached link (in 2012) was not allowed to in her state..
