Where a house forms part only of any premises, the reference in section 13(1)(b) to the house includes reference to any part of those premises which the owner of the house is responsible for maintaining (solely or in common with others) by virtue of ownership, any real burden or otherwise.

Nothing in subsection (1) requires the landlord to carry out any work unless any part of the premises, or anything in the premises, which the tenant is entitled to use is adversely affected by the disrepair or failure to keep in proper working order.
