(Fictional addresses and names have been used for this real situation.)
My friend Frank rents a non-stabilized first floor apartment in a privately-owned house. The address is 100 Fictional Street.
The house addressed 102 Fictional Street is adjoined by one common exterior wall to 100 Fictional Street. That neighboring house is owned by a different LL.
(What I am describing as a common wall is probably really two exterior walls touching each other although that seems to be insignificant.)
Satan rents a non-stabilized first floor apartment at 102 Fictional Street.
Satan is constantly playing his stereo system very loudly. Frank has made repeated attempts by verbal communication only, so far, with his own LL and with Satan to get the loud-noise problem resolved. The problem persists however.
Can Frank take steps to break his lease due to Satan’s refusal to lower the music’s volume?
Can the Warranty of Habitability be applied here or is Frank’s LL completely absolved of any responsibility because of the fact that the noise is being generated from a property not owned by Frank’s LL?
(Both Frank and Satan have leases which shall not expire soon.)
