New Mexico Light Trespass (2026)

Key Facts

Authority: NMSA 74-12-1 et seq.
Direction: Light below horizontal
Enforcement: Building official
Civil action: Nuisance claim available
Max fine: $250

Full Breakdown

Under NMSA 74-12-1 et seq., all regulated outdoor lighting installed in New Mexico must be fully shielded so the light source is not visible from neighboring properties and light is directed below the horizontal plane. This functions as a statewide light-trespass standard. The Construction Industries Division enforces compliance through building permits. Property owners experiencing light trespass from non-compliant fixtures can file complaints with local building officials. Common-law nuisance claims also remain available where bright lighting unreasonably interferes with the use of adjacent property.

Violations & Penalties

Civil penalty up to $250 per violation; permit revocation; private nuisance lawsuits seeking injunctions and damages may also proceed.

Frequently Asked Questions

What can I do about a neighbor's bright security light shining into my window?

Document the light, request shielding, and report to your local building official under the Night Sky Protection Act. You may also pursue a private nuisance claim in district court.

Are motion-activated security lights regulated?

Motion-activated fixtures are allowed but must still be shielded to direct light downward when activated. Lights triggering frequently across property lines may constitute light trespass.
