For a landlord to avoid liability for work contracted for by the tenant, the landlord must include a provision in the lease prohibiting such action and record a memorandum of that provision of the lease in the public records of the county in which the property is located. If you are unsure of your rights and responsibilities as a landlord, you should consult an experienced real estate lawyer in your area.

No. Without the landlord's permission, the tenant then becomes responsible for any damages that occur. I can't imagine a contractor not checking with the landlord. The contractor can be sued for damages as well.
