Summary

Howard County has no year-round odd/even watering ban. Water use is limited only when the state declares a drought. Under Maryland's Level One Mandatory Restrictions, watering grass is prohibited and outdoor water use is sharply curtailed; between droughts the county asks residents to conserve voluntarily.

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

Watering of grass is prohibited... Washing paved surfaces such as streets, roads, sidewalks, driveways, garages, parking areas, tennis courts, and patios is prohibited.

Full Breakdown

Howard County's Bureau of Utilities supplies public water to more than 85% of residents and follows Maryland Department of the Environment drought declarations rather than a permanent watering calendar. When a drought emergency is declared, MDE's Level One Mandatory Water Use Restrictions prohibit watering lawns, ban sprinklers on gardens and landscaping (hand-held containers with shutoff nozzles are allowed), and stop washing paved surfaces and non-commercial vehicles. During the milder drought watches and warnings issued in 2025-2026, the Baltimore-region counties, including Howard, urged voluntary cuts in non-essential outdoor water use. Newly seeded areas and permitted athletic fields get limited exceptions.

Violations & Fines

During a declared drought emergency the mandatory MDE restrictions are enforceable; voluntary-stage requests carry no fine but the county asks users to cut consumption by about 10%.

Frequently Asked Questions

Can I water my lawn in Howard County?

Are current restrictions mandatory?
Recent 2025-2026 Baltimore-region measures were voluntary, asking residents to limit non-essential outdoor water use. Mandatory limits apply only once the state formally declares a drought emergency.
