My entire building is in an uproar because there was a notice given that starting immediately the basement door will be locked from the hours of 9pm until 9am. The reason for this is unknown, although we suspect that it is our first floor neighbor complaining about any squeak or creak they hear during the night when someone brings down their garbage, washes their clothes, or goes to their storage space. What I want to know is wether or not it is legal to lock tenants away from their personal belongings so early at night or at all for that matter?
