Shut off water without notice

(MA US) Theyre renovating 2 units in my building, the one right above me and one on the first floor. This weekend I had no hot water during the day, although it returned later in the evening. I chalked it up to a tapped out water heater.

This morning im off work and find my water isnt working at all. Im assuming it was shut off for the renovations, but I was given no notice about this being the case, and casts a different light on the issues this weekend. I know that without emergency they cannot legally shut off my water, but it'll also probably be back on by 4pm.

Im trying to decide how much energy I want to waste on this. I did submit a maintenance ticket, did some legal research, and Im debating if I want to deal with storming into the office only to get a bunch of platitudes when I have 8 million errands to run today.
