All landlords adjust their unit prices for long-term tenants. But in the Bay State, you can’t just send a casual text and call it a day. Instead, you have to comply with all Massachusetts rent increase laws. Here’s what you need to know before you increase a tenant’s rent payment.

Massachusetts isn’t a rent-controlled state, and it prohibits local price stabilization ordinances. However, property owners must comply with the procedural requirements governing notice periods and delivery methods.

In this guide, we’ll explain these legal guidelines and how to write (and deliver) a rent increase letter. We’ll also provide TurboTenant’s free template to save you time and eliminate busywork.

Massachusetts Rent Increase FAQs

How much can I raise rent in Massachusetts?

Massachusetts isn’t a rent-controlled state. As a result, you can raise rent by any reasonable amount.

Is there a maximum late fee in Massachusetts?

No, Massachusetts law doesn’t cap late fees. Landlords can determine their own late payment penalties, but they must outline them in the lease.

Can I increase rent if the tenant is on a verbal agreement?

You can, but if you have a month-to-month lease, provide 30 days’ or 1 rental period’s (whichever is longer) written notice (Mass. Gen. Laws ch. 186, § 12). We recommend notifying tenants in writing for verbal fixed-term agreements as well.
