2027 Light Trespass Legislation
Texas Legislature · Proposed 2027 Session
Texas currently has no statutory remedy for property owners harmed by a neighbor's excessive, unshielded outdoor lighting. This initiative proposes two targeted amendments:
- Health & Safety Code §343 — adds light trespass as an actionable civil nuisance.
- Penal Code §42.01 — adds excessive light trespass to disorderly conduct, with clear lumen thresholds (≤2,000 lm at ≥2700K; ≤3,000 lm below 2700K).
