DC light trespass complaints are handled through DOB Property Maintenance under DCMR 14-802 (nuisance) and DC Code 22-1321 (nuisance/disorderly). Residential fixtures aimed or shielded improperly so that illumination falls on neighboring property can be cited as a private nuisance. Commercial lighting must meet specific property-line lumen limits under the Energy Code. Complaints are filed via 311.
DC treats light trespass primarily as a nuisance issue rather than under a dedicated lighting ordinance. The general property maintenance provisions at DCMR 14-802 prohibit conditions that constitute a nuisance to neighboring properties, which case law has extended to include persistent, unreasonable artificial light intrusion. DC Code section 22-1321 (unlawful to annoy, alarm, or disturb) provides criminal backing for extreme cases. The DC Energy Code (12-I DCMR) Section C405.6 requires commercial and multi-unit residential projects to meet BUG rating (Backlight-Uplight-Glare) standards so that light is contained on-site: residential-zoned receiving property lines must receive no more than 0.1 foot-candle of commercial spillover, and commercial-zoned lines no more than 0.5 fc. Residential-to-residential cases are resolved through nuisance complaint — MPD may respond to disturbance calls, DOB issues property maintenance notices, and civil suits are available for persistent unresolved trespass. Holiday and seasonal lighting receives broad tolerance from November through early January. Flood lights and motion-sensor security fixtures must be aimed downward and shielded to illuminate only the owner's property; 'sky-beam' or upward-aimed searchlights require a DDOT air rights permit. Advisory Neighborhood Commissions often mediate neighbor-to-neighbor lighting disputes informally before escalation to DOB.
Residential light trespass nuisance: DOB notice, 30 days to correct, $100-$500 fine. Commercial BUG rating failure: $500-$2,000 Energy Code violation. Repeat or flagrant: up to $1,000 plus civil tort exposure. Sky beams without permit: $500-$2,000 FAA coordination issue possible.
