What the HRCA allows
The Highlands Ranch Community Association doesn’t require Architectural Committee approval for temporary holiday lights and decorations. Its holiday decorating page says decorations may go up 30 days before the holiday and must come down 30 days after, and the Residential Improvement Guidelines say clips and hooks added to hold temporary lights must also be removed within 30 days after the holiday, weather permitting. January takedown is part of your price.
