An Act relative to property tax exemptions for the increased value of a home as a result of certain alterations and improvements to the home

This bill creates a property tax break for homeowners who make specific modifications to their homes to accommodate elderly or disabled tenants. It allows a $500 annual reduction in property taxes for improvements made to provide housing for someone aged 60 or older, or a disabled person (as defined in the bill), who is not the home's owner. The home must have been a single or multi-family residence with no more than three units before the changes, and the homeowner must annually confirm the tenant's eligibility. The exemption ends if the tenant no longer lives there and cannot be claimed more than once per year by a single homeowner.
