Reduces term of affordability required for affordable housing created through middle housing construction or conversion.

This bill reduces the required affordability term for certain affordable housing units from 30-40 years to just 10 years. It specifically applies to housing created through "middle housing" construction (buildings with 2-4 units) or "middle housing conversion" (renovating existing buildings with up to 4 units to increase low- and moderate-income housing). The bill aims to encourage denser housing development by making it easier for developers to create affordable housing with shorter affordability requirements. This change directly affects developers building middle housing, municipalities that count these units toward their affordable housing obligations, and housing programs that finance such projects.
