If a utility company disconnects service, or gives written
notice that service is about to be shutoff because a
landlord who is supposed to furnish utilities has not paid
the utility bill, then the landlord is liable to the tenant
[regardless of whether the unit is "all bills paid,"
submetered or mastermetered]. If this happens, the tenant
can terminate the lease and move out immediately or within
30 days of receiving the first notice, as long as the
landlord has not presented evidence that the utility bill
has been paid prior to the tenant's termination. So be sure
to give your notice in writing, date it and keep a copy. If
you properly terminate the lease and plan to move, you may
deduct your security deposit from your last month's rent
(if you have not paid it yet), and sue for actual damages
(such as moving expenses), court costs and attorney fees.
But note, that you may be in for a fight if the landlord
disagrees.
Rather than terminate the lease, you can try to avoid the
shutoff by reconnecting the utility in your name and
deducting the amounts paid to the utility company from your
rent. You may have to organize most of the tenants of the
complex in order to be able to negotiate successfully with
the utility company.
