What does HM mean in the Unit number field?
 

• HM generally stands for House Meter. If you see HM listed for a Service Address, it usually means the meter is used for shared amenities, like laundry rooms, community rooms, clubhouses, walkway lighting, or other common services. This helps provide these conveniences to everyone in your community.
• If there are multiple Service Addresses with the Unit or Premise type of HM (House Meter), please double-check that the last four digits of the meter number match before turning on the meter. This will help make sure you activate the correct one. For tips on locating your meter number, click here.
