Which items does a landlord repair & wear-and-tear of tenants?

[Claudia Schmidt]

1) Can anyone please help me determine what is normally a landlord's responsibility in terms of maintenance of a rental property?

2) And what are the items that should be repaired by the tenant through regular wear-and-tear? My rental properties are long term.

3) Do you detail this in the rental contract so that it's clear for both parties? If so, can anybody please share with me a sample of their rental contract clause please?

4) Is painting the apartment something the landlord has to include every year? Every 2 years? Should it be mentioned in the contract too?

Thank you in advance for your advice! Much appreciated!
