Sewer line repair in New York City
Updated · Editorial team; not yet technically reviewed
Short answer
In New York City, the property owner is responsible for the sewer service line from the point it leaves the building up to and including the connection to the city sewer in the street. If DEP finds a defect, it can issue a repair order. Sewer line breaks are among the costliest owner repairs in the city because most of them mean opening the street.
What's different in New York City
The owner must maintain and correct any defect in the sewer line from where it leaves the building up to and including the connection to the city sewer in the street. [1]
DEP issues a written repair order when an owner's sewer line defect must be corrected. [1]
DEP has cited average owner costs of about $10,000 to $15,000 for a sewer line break and $3,000 to $5,000 for a water line break. [2]
Why NYC sewer repairs cost so much
The connection to the city sewer is often under the middle of the street, so the work involves street opening permits, traffic control, shoring a deep trench and restoring pavement to city standards. A camera inspection that pins down the defect keeps the opening to one spot.

The order sets a time to make the repair.
Get a licensed master plumber

Multifamily and attached buildings
In rowhouses and small apartment buildings, one house sewer may serve several units, and a backup affects everyone below the blockage. For one-off clogs, drain cleaning is the first call; for storm backups in basements, see preventing basement sewer backups.
