Summary

Columbia, Missouri exempts holiday and seasonal illuminated displays from the Unified Development Code's exterior lighting standards, but any seasonal light fixture still cannot be aimed to create glare or spill light onto neighboring property in Boone County.

Seasonal decorations that include illuminated displays are exempt from this section except that no light fixture that is part of a seasonal display shall be aimed or directed to create glare or light spillage.(vii)This section shall not apply to the installation of an outdoor lighting structure if an application for a building permit involving the installation of that structure was received by the city on or before December 4, 2006.(2)All outdoor facilities intended for nighttime use (5:00 p.m.—7:00 a.m.) shall be illuminated and such illumination shall be maintained in compliance with the standards of this section.(3)Searchlights and similar spot light fixtures, such as moving, flashing, chasing and strobe lights used to attract attention to a place are prohibited.(4)For enhanced security, only light sources with a color rendering index (CRI) of greater than sixty (60) shall be used. See Table 4.5-1 for CRI range of lamps.(5)Any light source or lamp that emits more than nine hundred (900) lumens (13 watt compact fluorescent or 60 watt incandescent) shall be concealed or shielded with an IESNA full cut-off style fixture with an angle not exceeding 90 degrees to minimize the potential for glare and unnecessary diffusion on adjacent property.

Full Breakdown

Columbia's Unified Development Code regulates most outdoor lighting under UDC § 29-4.5, covering fixture shielding, footcandle limits, and photometric plans for permanent installations. Seasonal decorations with illuminated displays are carved out of that entire section: no permit, photometric plan, or shielding standard applies to a homeowner's holiday lights anywhere within Columbia city limits. The single carryover restriction is that no light fixture that is part of a seasonal display may be aimed or directed so it creates glare or spills light onto adjoining property. This is a city ordinance and does not reach unincorporated Boone County.

Violations & Fines

Community Development can order a glare-producing seasonal light fixture redirected or removed under the UDC's general violation, enforcement, and penalty provisions in § 29-6.6; the seasonal exemption itself carries no fine or permit fee.

Frequently Asked Questions

Do I need a permit for Christmas lights in Columbia, Missouri?
No. Seasonal illuminated displays are exempt from the city's exterior lighting standards under UDC § 29-4.5(d)(1)(vi), though fixtures still cannot be aimed to create glare or spill light onto neighbors.
Can my neighbor complain about my holiday lights?
Only if a fixture is aimed to cause glare or light spillage onto their property: the seasonal-display exemption in Columbia's code does not cover that specific misuse.
