Rental compliance, registration and inspections

Registration and periodic inspection of rental units is set by each city or town, not by the state, and the requirements differ meaningfully between neighbouring municipalities. Boston operates a formal rental registration and inspection regime for non-owner-occupied units; other cities in the region have their own arrangements, and those change.

We will not tell you what a given city requires without having confirmed it, because a confident wrong answer here is what produces a fine. On the city pages we say plainly where a requirement is established and where we have not verified it. For properties under management, confirming the current requirement is part of the job.

Massachusetts regulates residential security deposits tightly: what may be collected at the start of a tenancy, how the money must be held, what must be given to the tenant and when, and what must happen at the end. The penalties for getting it wrong are statutory rather than discretionary and can substantially exceed the deposit itself.

This is stated as of 2026 and is a general description, not legal advice — the statute is detailed and a specific situation deserves a specific answer from a Massachusetts attorney. What we can say is that this is the most common way an otherwise careful owner ends up on the wrong end of a claim, and that the fix is procedural: do it right at the start and keep the paperwork.

The state sanitary code sets minimum standards for residential rental housing — heat, hot water, working facilities, structural and sanitary condition — and those obligations run for the whole tenancy rather than being satisfied once at move-in.

Practically, that means a maintenance system that responds rather than defers, and a record showing that it did. Both are part of managing a property properly rather than an extra.
