HB 120 Montana House · 2025 Regular Session

Revise commercial property assessed clean energy laws

HB 120 expands Montana's Commercial Property-Assessed Clean Energy (C-PACE) program to include multifamily housing facilities with at least five residential units. This change directly affects property owners and developers of qualifying multifamily buildings (e.g., apartment complexes), allowing them to finance energy efficiency and renewable energy upgrades through property assessments. The bill amends definitions to explicitly include these residential properties under the program, covering improvements like insulation, solar panels, and energy-efficient appliances. It maintains the existing financing mechanism where costs are repaid through property taxes over time, without requiring new debt or upfront payments from property owners. The law took effect immediately upon the governor's signature on April 7, 2025.
