MARICOPA, Ariz. - Twelve homeowners with the City of Maricopa are competing for the best decorated Halloween house.

"This is our twelfth year," said Niesha Whitman, the special events and marketing manager for the city. "This year something new that we did was start putting some of the pictures on Facebook. All the homes are looking at the other homes and saying, 'Wow, I really need to step up my game next year.'"

A full list of the houses (with photos) can be seen on the "Mysterious Mansion Mayhem Home Decorating Contest" Facebook page.

Voting begins at midnight Saturday morning.
