Water restrictions in Howard County, MD — also called the watering schedule, outdoor irrigation rules, or drought ordinance — set which days and hours you can run sprinklers or irrigation.
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.
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.
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%.
