Even though the water system in Baltimore County belongs to Baltimore City, the County is responsible for the use of the fire hydrants in the County by the public. The Fire Hydrant Utilization Policy (PDF) must be followed and a fee is charged by Baltimore County to use one of these fire hydrants to fill swimming pools, irrigate landscaping, wash down construction sites, etc.
You may apply for a permit to use a fire hydrant in Baltimore County through the Department of Permits and Development Management.
A sample of the Fire Hydrant Connection Permit (PDF) and regulations are provided here only as a reference. The actual permit cannot be accessed via the Internet.
