How these estimates work
Pricing reflects our real 2026 rate card: single-family new construction $1,850–$2,500, ADUs $1,600–$1,850, multifamily $900–$1,450 per unit, additions and renovations from $600, duct leakage tests from $350, REScheck reports from $300, and COMcheck from $600. Every estimate includes the full compliance package: REM/Rate energy model, pre-drywall inspection, blower door testing (3.0 ACH50 target for new construction), duct leakage testing where required (max 4 CFM25 per 100 sq ft), and the final HERS certificate for your building department.
Score targets follow the 2025 Massachusetts Stretch Energy Code Technical Guidance: HERS 42 for new mixed-fuel homes, HERS 45 for all-electric, HERS 52–55 for ADUs, and tiered targets of roughly HERS 52–75 for major additions and renovations. Towns on the Specialized (Opt-In) Code layer electrification requirements on top — talk to a rater if your town has opted in.
