In a detached house, the main shut-off valve is usually in the basement or crawl space where the water line comes through the foundation, often near the water heater or laundry hookups.
Part of every residential service line in the Baltimore water system is privately owned: the public system maintains the main, and the property owner is responsible for the line on their side into the house. Report a water main break in Baltimore County to the current Baltimore County water-service guidance from Baltimore City DPW. Leaks on your side of the meter need a plumber.
