Enforcement Reality
Boston requires STR registration through the Inspectional Services Department and enforces a strict owner-occupancy rule: only properties where the owner lives on-site for at least 9 months per year qualify for investor-type rentals. Fines for non-compliance start at $100 per day and escalate. The city uses a dedicated STR enforcement team that cross-references platform data with registration records. Investor-owned units in multi-family buildings are the primary enforcement target.
This is not a hypothetical. It is enforcement data.
Fines compound. One violation becomes two becomes a shutdown.

Overview
Boston has a three-tier STR system: Limited Share ($25/yr, owner present, renting bedrooms), Home Share ($200/yr, whole unit while absent), and Owner-Adjacent ($200/yr, secondary unit in 2-3 family building). All require primary residence (≥9 months/year). The Owner-Adjacent path is the only legal route to STR an investment property : you must live in another unit of the same 2-3 family building. This is more nuanced than our original assessment and creates a narrow but real investor path: buy a 2-3 family, live in one unit, STR the other(s). Source: boston.gov Inspectional Services.
