Rent increases larger than 3% would be allowed only if the landlord has made
substantial changes to the property that provide a material benefit to tenants. This
wouldn’t include changes that are required by law (such as meeting the Healthy
Homes Standards or routine upkeep), but could include major kitchen or bathroom
renovations. The increase would have to be agreed by the tenants and the landlord
before the work is undertaken.
