When a loss crosses several units

A riser failure on the twelfth floor is a construction problem for a day and a governance problem for a month. Multi-unit losses are rarely difficult because of the building work. They are difficult because several parties, several policies, and a lot of anxious residents all attach to the same event.

Document per unit from the start

In a condominium or co-op, the building policy and the unit owner policies are separate instruments covering different things. A single blended scope covering four apartments is very difficult to allocate afterwards, and the attempt to allocate it is where neighbors start disagreeing with each other.

Separate records per unit, from the first walkthrough, prevent that. Each unit gets its own photographs, its own readings, its own line items. It is slightly more work on day one and it removes an entire category of dispute on day thirty.

Decide who talks to residents, and make it one person

In a multi-unit loss the thing that fails is almost never the construction. It is three parties giving residents three different timelines. The contractor tells someone in the hallway one thing, the managing agent's office says another, and a board member answers a question in the elevator with a third.

Pick one channel and route everything through it. Residents tolerate bad news far better than contradictory news, and a timeline that moves once with an explanation beats one that was never given.

Expect the units that never saw water to be affected

Smoke and moisture both travel through shafts, chases, and the gaps around risers. The complaint from two floors up, in a unit with no visible damage at all, is usually real. Odor in particular migrates well beyond anything anyone would predict from looking at the loss.

Inspect further than the obvious perimeter, and record the units you checked and found clear. Proving what was unaffected is part of the record.

Access is the schedule

• Notice periods that residents genuinely receive, not notices posted the night before
• Work hours the building's rules actually permit
• Protected paths through occupied common space, every day, not just on inspection day
• Elevator and loading dock time booked rather than assumed
• A plan for units where nobody is home, agreed before the crew is standing outside the door

On a multi-unit job, access failures cost more days than the work does. A crew that cannot get into two apartments on a Tuesday has lost the day for those units, and drying does not pause politely while that gets sorted out.
