Local homes

What Cambridge homes need

Cambridge mixes 19th-century workers' cottages, triple-deckers and Victorian single-families with university, lab and multifamily buildings. Tight lots and shared walls make air sealing and sound control as important as R-value.

In Cambridgeport, Mid-Cambridge, North Cambridge and East Cambridge, homes are close together and often split into condos, so insulation work usually needs agreement between owners and careful planning around shared attics and basements. Many buildings still have original balloon framing with open paths from the basement to the attic.

From the inner suburbs to MetroWest, Middlesex County homes range from 19th-century two-families to large newer colonials, each with different weak spots.

Recommended plan

How we would assess a typical two- or three-family home in Cambridge

Step 1

Test each unit

Blower door tests show which units leak the most.

Step 2

Scan the shell

Thermal imaging finds leaks between units and at the roof.

Step 3

Prioritize upgrades

We rank upgrades by cost and impact.

Step 4

Re-test

Testing after the work confirms the results.

In older homes, a blower door test shows exactly where air leaks, so upgrades go where they matter most.

Climate & code

Climate zone 5A targets

In climate zone 5A, which includes Cambridge, recommended attic levels are R-49 to R-60, well above what most homes built before the 1980s were given. Many Massachusetts towns have adopted the Stretch Energy Code or the Specialized Opt-in Code, which raise insulation and air-sealing requirements for new construction and major renovations.
