Water reaches a ceiling under another apartment
Notify the appropriate building contact and preserve the symptom timeline. A stain shows where water appeared, not necessarily its origin.
An upstairs room is a lead, not a verdict
A ceiling stain beneath another apartment may need access on more than one floor. Describe the timing and location to the building contact without diagnosing the upper residence from below. Water appearing at a ceiling does not establish whether the source is supply plumbing, drainage or another path.
Keep the repair and ownership decisions distinct
Ask what evidence locates the source and which permissions are needed for any proposed opening. The relevant building documents determine responsibility; a stain does not replace them. Confirm who will authorize source correction and who will arrange the affected finish, including any investigation not covered by the first accepted scope.
Locate the leak before repairing finishes
Ask what findings locate the source, leaving association or owner responsibility to the actual documents. Detection, pipe work and restoration can need separate authorizations.
