Howard County sets no countywide maximum lawn height for owner-occupied homes. Overgrowth is enforced only where it becomes a health nuisance (vermin, refuse). Rental housing must meet the adopted International Property Maintenance Code.
Unlike some cities, the Howard County Code contains no fixed grass-height limit for owner-occupied single-family lots. Weed and overgrowth complaints on such properties are handled under the Health Code nuisance provision (Sec. 12.110) when the condition harbors vermin or refuse that threatens health. For rental housing, Howard County has adopted the 2024 International Property Maintenance Code as the Property Maintenance Code for Rental Housing (Sec. 3.700), whose exterior-property standards require grounds be kept free of weeds and plant growth. Homeowner-association covenants in Columbia and other communities often impose stricter, privately enforced lawn standards.
Nuisance overgrowth: Title 24 civil penalty (Class E to Class B) or fines to $1,000. Rental IPMC violations enforced by the Department of Inspections, Licenses and Permits.
