Ask a landlord-tenant lawyer and get answers ASAP
are you asking if you must allow the repairs or set any conditions?
Courts expect repairs to be done at date and time suitable for both sides without much interference with use. LL may not enter at will, and tenant may not object to all times. Courts expect both sides to be reasonable for benefit of the premises and the parties involved.
Let me know if that is clear and acceptable.
You may file a complaint in court seeking a definite schedule and rent credit for affected period.
