Revise commercial property assessed clean energy laws

This bill amends Montana's Commercial Property-Assessed Clean Energy (PACE) program to expand financing opportunities for multifamily housing facilities with at least five residential units. It updates legal definitions to explicitly include multifamily properties and clarifies what qualifies as an energy conservation measure, such as insulation, window upgrades, HVAC modifications, and electric vehicle charging stations. The changes allow local governments to establish districts within their jurisdictions to administer these financing programs, enabling property owners to pay for energy efficiency improvements through property assessments rather than traditional loans. The bill takes effect immediately upon passage and approval by the legislature.
