In the days leading up to an election people often show support for a political candidate by placing signs in front yards and windows. Once the election's over, however, these signs become "political litter" and it's time to remove them.
Check With the City
In the United States, the deadline for removing signs from your yard varies from city to city. For example, in San Ramon, California, you must remove signs within 10 days after the election and in Tuscon, Arizona, you're allowed 15 days, but in Newton, Massachusetts, you only have two days following the election to take down the signs. In addition to this, your homeowner's association, apartment's lease agreement of condominium or co-op board may have alternative rules. If you're not sure, it's always safe to remove the signs the day after election.
