If a proprietor wishes to increase the rent they must provide written notice stating the date that the increase takes effect. However, a proprietor may be prohibited from increasing rent if the right to do so has been excluded or limited by the terms of the rooming house agreement. Where accommodation is to be provided for a fixed term the rooming house agreement is taken to exclude an increase in rent during this time unless there is a specific term allowing for an increase.

Where a rent increase is allowed it must be at least 6 months after the date of the rooming house agreement or, if there has been a previous rent increase, the date of the last rent increase. The proprietor must give at least 4 weeks notice of an increase [Residential Tenancies Act 1995 (SA) s 105I].
