Plympton is a Stretch Code town: the state's adoption list shows it in effect since 2013.

• New homes: HERS 42 if mixed-fuel or HERS 45 if all-electric, or Passive House certification
• Additions and renovations over 1,000 sq ft or over 100% of the existing home: a HERS 65/70 rating on the finished house
• Smaller additions and alterations: REScheck or the prescriptive path
• Commercial: COMcheck for buildings up to 20,000 sq ft

Plympton is an MBTA Communities (Section 3A) adjacent small town and appears on the state's compliant list.

Running the HERS model at the design stage shows whether the walls, windows and heating plan reach the target before anything is ordered.

On a renovation, the rating covers the whole house after the work, so the existing walls and attic can decide whether HERS 65/70 is within reach.

On most jobs the rater visits twice: at pre-drywall to check insulation and air sealing while they can still be fixed, and at final for the blower door, duct leakage and ventilation tests.

REScheck compares the planned insulation, window and air sealing values with the code tables, which suits small additions and alterations with a simple envelope.

The energy paperwork is reviewed when the permit is issued and again before the certificate of occupancy, so the final report should match the approved plans.

Heat pump sizing, duct location and the ventilation plan are easiest to settle before framing, and those choices move the HERS score more than most finishes do.
