An Act relating to improvements to residential properties

HD 1901 creates a program allowing municipalities to finance specific residential property improvements through "betterment assessments." It directly affects homeowners in participating cities or towns who want to install qualifying upgrades like sewer system repairs, roof reinforcements, flood mitigation, energy-efficient systems, or renewable energy installations on properties with four or fewer dwelling units. Municipalities must opt-in via local vote to administer the program, and financing is repaid through liens on the property tied to the improvements, with assessments accruing interest as market rates (not capped). The bill defines "qualifying improvements" broadly to include both safety upgrades (e.g., flood barriers, hurricane-resistant windows) and efficiency measures (e.g., insulation, solar panels), but does not require homeowners to participate.
