On building storm drains requiring a manhole, the manhole shall be what distance or less from the building?

The correct distance for a manhole to be located from a building is 15 feet. This requirement is based on ensuring proper access for maintenance and operations, as well as minimizing the risk of water infiltration into building foundations. Placing the manhole too close to a building could hinder access and create potential safety hazards during maintenance activities.

Maintaining this distance also helps ensure that any water or debris flowing through the storm drain system does not impact the integrity of the building's structure or its surrounding landscape. This standard is established to promote efficient drainage management while safeguarding property and public safety.
