Massachusetts Stretch Code Town Map

Massachusetts Stretch Code Towns Map

Not all Massachusetts cities and towns have yet adopted the Stretch Code, but those which have are indicated on the map and are enforcing its provisions with tenacity.

Stretch Code townships, however, operate under a different set of design and testing standards, which require outside resources such as HERs raters be used by builders for all areas of energy compliance, thereby relieving the building department(s) of this portion of the building construction review & inspection.
