Tewksbury is dominated by postwar capes, ranches and garrison colonials, many still close to their original footprint and layout. That makes it strong dormer and rear-addition territory — expanding upward or backward is usually cheaper here than moving. Outlying neighborhoods are on septic, so Title V capacity governs whether a bedroom can be added at all. We check that before scoping anything, because it is the constraint most likely to change the answer.
Tewksbury never adopted an ADU bylaw, so the state law applies to your lot directly — and the legacy Family Suite bylaw still on the books can no longer be enforced against a protected ADU. Most of the town is sewered, which takes the usual project-killer off the table. The postwar capes and garrison colonials here are strong dormer and rear-addition territory.
