I would want as many hand tools as I could accumulate so I could make modifications to my building. Im not an apartment dweller but after shtf I would start making alterations to my building to suit the situation.
If there are empty apartments I would set one up with storage barrels. A lot of buildings can have the roof drainage system modified to divert water to a new location. Just cutting a hole in the wall near the down spout and adding an elbow will bring it indoors.
I would suggest a good supply of large nails and a framing hammer for use in securing the building and individual doors as needed. An edge nailed door (both edges) with a board nailed to the floor behind the door, won’t open until the door collapses. Reinforcement to the door can be added as needed.
