What MassDEP has recorded
- RTN 3-0014370 — No Location Aid, activity and use limitation, status RAO, class B2, AUL recorded October 16, 1996 · MassDEP file
Within about 500 m (a third of a mile): 5 active tier-classified 21E sites and 7 sites with an Activity and Use Limitation. All MassDEP sites in Boston.
What this means
- Assessed 1255% above the median residential condominium in Boston ($1,926,500, 10,170 parcels).
- An Activity and Use Limitation is a deed restriction: it limits how the land may be used (often no residential use or no digging) and passes to every buyer.
- Built before 1978: the Massachusetts Lead Law applies when a child under six lives there; ask for any lead inspection or letter of compliance.
