Water leaking from the apartment upstairs: what to do

First stop the water, then build your file.

The answer in 2 lines. Go upstairs and ask your neighbor to turn off their water. If no one answers, call your landlord, super, property manager or HOA emergency line: they can shut off the water. Keep away from water near light fixtures and outlets. Photograph and film everything before cleaning up, tell your landlord or HOA in writing, and report the damage to your own renters or condo insurer as soon as you can. Whose insurance pays depends on where the leak came from, who was negligent and your policies.

The first 3 steps

Go upstairs and ask your neighbor to turn off their water. No answer: call your landlord, super, property manager or HOA emergency number (often posted in the lobby or on the lease).
In your place: buckets and towels, move furniture, electronics and valuables away, and don't turn on lights in the wet area.
Take dated photos and video of everything (ceiling, walls, floors, damaged belongings) before you mop up, and keep damaged items for the adjuster.

Stop: danger

Water near a light fixture, outlet or the electrical panel: don't touch anything wet. Turn off power at the breaker only if the panel is dry and you can reach it without stepping in water; otherwise leave and call 911 or your power company.
Ceiling sagging or bulging with water: leave the room and keep everyone out; it can come down. If it's dangerous, call 911.
Never break into your neighbor's unit yourself. The landlord or building management can usually enter in an emergency; if there's danger, firefighters decide.

The steps, in order

Right away: get the water shut off, protect your things, photograph and film.
Same day: write to your landlord or property manager (text or email so there's a record); condo owners tell the HOA or management company. Get the upstairs neighbor's name, phone number and, if they'll share it, their insurer.
As soon as you can: report the damage to your own insurer (renters policy, or condo/HO-6 policy). Policies require prompt notice. Reporting is not the same as getting paid: the insurer decides after looking at the cause.
Next: an adjuster may visit. Make a room-by-room list of damaged items with photos, and receipts or bank records if you have them.
After drying and the insurer's go-ahead: repairs. Keep every receipt, including emergency drying or hotel costs.

Who pays: the usual picture

Your belongings (renter): your renters policy usually covers personal property damaged by sudden, accidental water, minus your deductible. The landlord's policy covers the building, not your things (Triple-I). Your insurer may later try to recover what it paid from the neighbor's insurer if the neighbor was at fault.
The neighbor's liability: if the leak came from their negligence (an overflowing bathtub, a washer hose they ignored), their renters or condo liability coverage may pay for your damage. If it came from the building's pipes or roof, it's usually the landlord's or the HOA's side (Policygenius).
Walls, ceilings, floors: in a rental, the landlord repairs them. In a condo, the split between the HOA's master policy and your HO-6 policy depends on your building's bylaws and the master policy (Amica, condo vs. homeowners insurance).
No renters insurance? You can ask the upstairs neighbor (or their insurer) and the landlord to pay, in writing; if they refuse, small claims court is the usual next step. Limits and procedures depend on your state (Lemonade's step-by-step guide).
Exceptions: damage from long-running slow leaks may be excluded (NAIC), and rising water from outside (storm surge, river) needs separate flood insurance, even for renters (NYC Emergency Management).

This is general information that varies by state and by policy, not advice on your case. If the insurer refuses or delays, your state insurance department handles consumer complaints.

Likely causes

"Only when they shower": a shower pan, caulking or drain problem.
"Even when they're away": a pressurized pipe, supply hose, water heater, or a shared riser in the building.
"After laundry": the washer's drain or supply hose.
"They say it's not them": it may come from a floor higher up, the roof, or a common pipe. That's for the landlord, HOA or a plumber to trace.

What not to do

Throwing out damaged items before the insurer has seen them or the photos.
Starting repairs (paint, drywall, flooring) before the insurer agrees and before everything is dry.
Turning back on wet light fixtures or outlets before a licensed electrician has checked them.
Waiting to dry things out: mold can start within a day or two.

Good to know

Swap phone numbers with the neighbors above and below you, and keep the building's emergency number in your phone.
Keep photos or receipts of your valuable belongings in a cloud folder: it makes any claim faster.

On a Saturday in Brooklyn, Aisha sees water dripping from her bathroom ceiling. Her upstairs neighbor isn't home, so she calls the super's emergency number and he shuts off the water to that line. She films the damage, emails her landlord, and calls her renters insurer the same day. The adjuster covers her ruined rug and laptop minus her deductible, and the landlord repairs the ceiling.
