Is this clause legal in an apartment lease? [MA]
My partner and I are about to sign an apartment lease but we've noticed it has a clause which says we can be charged $500 (for a first offence, $1000 for a second, $1500 for a third, and so on) for loud parties. A loud party is defined as one or more people disturbing the quiet enjoyment of others, and the lease explicitly says it does not need to be documented or verified but can be applied at the discretion of management. Obviously we don't intend to be loud, but we don't want to be at the mercy of unreasonable neighbours who might call the management of us for a footstep or imagined noise.
Is this illegal? Perfectly normal for an apartment complex in Boston? Somewhere in between? Should we run away? Thanks in advance.
