Summary
Clay County has no dark-sky ordinance for homes, but its Land Development Code requires commercial and industrial lighting to be shielded so the light source is hidden at any property line next to a residential or agricultural district. Cities may add their own lighting rules.
Lighting sources shall be designed and located so that the direct source of the light is shielded from view at all property lines abutting residential or agricultural zoning districts.

Full Breakdown
Missouri has no statewide dark-sky law, and unincorporated Clay County does not regulate residential porch or yard lighting. The county's lighting standards sit in the Land Development Code for commercial and industrial development: in the C-1, C-2, and C-3 districts, lighting must be designed and located so the direct light source is shielded from view at property lines abutting residential or agricultural zones (LDC Sec. 151-4.11). Airport-area development faces added glare limits under Sec. 151-5.5 to protect pilots. Kansas City and other Clay County cities apply their own lighting and glare provisions. For a neighbor's residential light, the practical remedy is a private nuisance approach.
Violations & Fines
Nonconforming commercial lighting is corrected through the county's zoning enforcement under LDC Sec. 151-14, which can require reaiming or shielding fixtures. Residential light disputes are generally handled as private nuisance matters.
