Q: How long may holiday lights be displayed?
A: The City's Municipal Code states that exterior holiday lights and decorations must be removed within 30 days of installation, and no later than mid January.

Besides contributing to blight, keeping holiday lights installed for an extended period of time creates the potential for a fire hazard because of their temporary-use nature.

Homeowners found not to be in compliance will be issued a courtesy notice to correct violation within 10 days. Failing to remove the lights within the allotted time frame can result in a $100 fine.

Q: Where can I store my trash containers?
A: All trash cans must be kept out of public view at all times. (Exception will be made on the evening prior to, and/or the day of your trash pick-up.) Rear yard storage of trash receptacles shall be screened by approved walls or fences from view of neighboring property, public and private streets, and public and private right-of-way.
