Ceiling Fell Down

[Ryan Ball]

Over the weekend we had a plaster (not drywall) ceiling fall down in one of our units.  It was about a 10 x 15 foot section in a living room.  Fortunately the tenant was not sitting under it.  Our property manager has not seen anything like it and we are at a loss to explain what caused it.  No water leaks or other visible causes.  We have owned the building for about 1.5 years and it was/is very well maintained.  Has anyone else ever seen something like this?
