Oak Lawn FAQ
What is light trespass?
Light trespass is unwanted light from one property shining onto another, such as a neighbor's floodlight illuminating your bedroom window or yard.
What should I do about my neighbor's bright lights?
Speak with the neighbor first; most issues are resolved by reaiming or shielding fixtures. If that fails, contact Oak Lawn Code Enforcement to investigate.
