Bill Summary · SD 117

Legislative bill overview

SD 117 establishes Massachusetts building standards and requirements designed to reduce greenhouse gas emissions and improve climate resilience in new and existing buildings. The bill likely includes mandates for energy efficiency improvements, electrification requirements to phase out fossil fuels, and resilience standards to protect buildings from climate impacts like flooding and extreme heat.

Why is this important

Buildings account for roughly 30% of Massachusetts' greenhouse gas emissions, making them a critical sector for meeting state climate goals. Requiring buildings to become "climate safe" addresses both mitigation (reducing emissions) and adaptation (preparing for climate impacts), while potentially reducing long-term energy costs for building owners and occupants through efficiency gains.

Potential points of contention

  • Cost burden: Retrofitting existing buildings to meet new standards could impose substantial expenses on property owners, landlords, and renters, with concerns about affordability and whether costs are passed to tenants
  • Implementation timeline and feasibility: Questions about whether buildings can realistically meet electrification and efficiency deadlines, and whether sufficient contractor capacity exists statewide
  • Regulatory scope: Debate over which building types should be covered, how stringent requirements should be, and whether exemptions for certain sectors (small buildings, historic properties, etc.) are appropriate
