A condominium owner (A) leased the unit to another (. B does not want to pay the rent because of the needed repairs in the unit. Since the cause of the uncomfortable use of the unit is the repair needed in the common area, the condominium corporation repaired the area. Pending the repair of the repair of the area the unit owner or lessor remains to be unpaid. The repair of the area was awarded to a contractor. Is there a way the unit owner can demand from the condo assoc to further demand the contractor to finish the contract of service.
