Arlington’s Historic Properties

This map shows all 1,226 properties on the town’s historic inventory. 873 are on the Arlington Historical Commission’s list, and 353 sit in one of the seven local historic districts. Pick a dot or a row to see what’s known about the building and open its paperwork: the inventory form filed with the Massachusetts Historical Commission and its record in MACRIS, the state’s historic database.

Properties come from the town’s Historic Commission Inventory map layer, which holds both the Historical Commission’s list and the properties in local historic districts. Each dot sits on the address point the town gives it.
Inventory forms link to the scanned form at the Massachusetts Historical Commission, found from each property’s MHC number. MACRIS turns away automated checks, so I couldn’t open every form to confirm it. A few records have no scan yet. If a form link fails, the MACRIS record link still shows what the state holds.
102 properties have no MHC number in the town’s layer, so they have no state paperwork to link to. Some are marked as not on the state’s list at all.
Protection lists what the town’s layer records: a local historic district, the National Register of Historic Places, or a recorded preservation restriction. Outside the districts, a building on the Historical Commission’s list is covered by the town’s demolition delay bylaw.
Two properties are marked demolished in the town’s layer. I’ve kept them on the map and said so.
