Alecia, the landlord, refuses to fix a small leak in the roof that was there prior to the current tenant. Joe, the current tenant, has just discovered the leak after a heavy rain. The consequence is that black mold has been forming in the attic for quite some time. Joe still has significant time remaining on his lease. Joe has notified Alecia in writing by email of the mold and leak issue but has received no response. He is concerned about the premises becoming unsafe to live in. It has been 14 days since he emailed her his notification.

What are all of Joe's options if Alecia declines to do the repairs?

Please discuss all remedies Joe may seek.
