Decorative displays for holidays may be displayed no more than 30 days before and 7 days after the specific holiday under SLCRO §1003.168. Displays on private property only — no public right-of-way placement.
Holiday displays are exempt from sign-permit requirements but must follow the 30/7 timing window. The rule applies to inflatables, Christmas lights, Halloween displays, and similar seasonal decorations. The county enforces the rule mostly by complaint; many cities (Clayton, Ladue) have stricter time windows or HOA overlays.
Notice of Violation; sign removal; minimal fines.
