What MassDEP has recorded
- RTN 3-0038382 — Multi-unit Residential, tier classified (active), status TIERI · MassDEP file
Within about 500 m (a third of a mile): 1 active tier-classified 21E site and 0 sites with an Activity and Use Limitation. All MassDEP sites in Watertown.
What this means
- The last sale price is 83% above the current assessment. Massachusetts assessments aim at full market value as of January 1 of the year before the fiscal year.
- A tier-classified site is a release still being cleaned up under the Massachusetts Contingency Plan; the MassDEP file shows the stage reached.
- Built before 1978: the Massachusetts Lead Law applies when a child under six lives there; ask for any lead inspection or letter of compliance.
