Local routing and responsibility
Tenants should first contact the landlord, managing agent or superintendent. If the leak remains unresolved, use the residential water-leak complaint route. Co-op and condominium residents should contact their board or management because repair responsibility depends on their agreements.
Repair decision and documentation
For an owner reporting outside water entering a basement, the water-leak category excludes storm-related rainfall. Use the sewer-backup route when appropriate instead. Keep photographs and request numbers, and begin safe drying promptly rather than waiting for complaint processing.

First identify whether water came from a building leak or storm-related sewer backup; the NYC311 routes differ. Tenants should notify the landlord or managing agent, while co-op and condominium residents should check board or management agreements. Photograph the source and affected rooms, preserve the request number, and arrange safe drying without waiting for complaint processing.
