Maryland sets no statewide lawn-height cap. In Harford County, grass and weeds may not exceed 12 inches on a residential subdivision lot under 5 acres, enforced by Planning and Zoning.
No Maryland statute limits grass height, so the binding rule in Harford County is local. County vegetation-control law prohibits letting grass or weeds pass 12 inches on any lot inside an approved residential subdivision that is smaller than 5 acres. Land in active agricultural use and areas platted as reforestation or forest-retention are exempt, and parcels over 5 acres outside a subdivision are unregulated. This targets neglected turf in Bel Air, Aberdeen, and Havre de Grace neighborhoods, not the rural north around Jarrettsville. The Zoning Enforcement Division of Planning and Zoning handles complaints and issues correction notices.
Zoning Enforcement issues written notice with a cutting deadline. If the owner ignores it, the county abates the growth, bills the cost as a charge against the property, and can add fines.
