Residential Tenancies Act 1986, ss 66H, 66I
When you move into a boarding house, the landlord must make sure that your room is clean and that no-one else is using it (unless you’ve rented it as a shared room). While you’re living there, the landlord mustn’t interfere with your reasonable peace, privacy and comfort, and they mustn’t unnecessarily interrupt the supply of electricity, water and gas. The boarding house as a whole has to be reasonably clean, secure and in reasonable repair, and it has to meet building and health and safety requirements.

You must have access at all times to your room and to toilet and bathroom facilities, and you must have access at all reasonable hours to the other facilities in the boarding house, like kitchens and laundries. The landlord must tell you and the other tenants immediately if the locks are changed.
