The bill amends Chapter 45-53 of the General Laws by adding a new section titled "Tiverton affordable housing units." It establishes that in the town of Tiverton, whenever the percentage of affordable housing is less than ten percent (10%), any developer must ensure that at least fifty percent (50%) of the units in their approved plans, permits, or projects are designated as affordable housing. This requirement remains in effect until the town achieves full compliance with the affordable housing standards outlined in chapter 53 of title 45. The act will take effect immediately upon passage.
