Summary

Maryland has no statute on residential light trespass, but Harford County's zoning code does. Section 267-79 requires light to be shaded, shielded, or directed so it does not reflect into neighboring residential lots or buildings, enforced through site-plan and code review.

These county ordinances apply to unincorporated areas of Harford County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Lighting shall be designed and controlled so that any light shall be shaded, shielded or directed so that light intensity or brightness does not adversely affect the operation of vehicles or reflect into residential lots or buildings.

Full Breakdown

No Maryland statute governs light spilling from one home onto another, so a Harford County resident bothered by a neighbor's floodlight relies on two paths. The first is the county zoning code: Section 267-79 requires lighting to be shaded, shielded, or directed so its brightness does not reflect into residential lots or buildings, a standard applied through site-plan review and code enforcement, mainly on commercial, mixed-use, and multifamily development. The second is a common-law private-nuisance claim, where a court can order an unreasonable light shielded, redirected, or dimmed if it substantially interferes with a neighbor's use of their property. For an ordinary house-to-house floodlight with no site plan, the nuisance suit is usually the practical tool.

Violations & Fines

Where the zoning standard applies, the Department of Planning and Zoning can require a noncompliant fixture to be reshielded or redirected. Otherwise a resident may bring a private-nuisance suit in which a court orders the offending light shielded or dimmed.

Frequently Asked Questions
