As a tenant, you are responsible for notifying the landlord of any defects or deterioration within a reasonable time. For example, if you notice the fridge is leaking but you fail to notify the landlord or take any preventive measures, your landlord could claim all or part of the repair costs from you. You are also responsible for leaving the unit in the same state as you found it. For example, if you damage the carpet and fail to repair it, the landlord can seek compensation from you.
