What is the Boston Short-Term Rental Ordinance?

Updated 2026-05-28

The Boston Short-Term Rental Ordinance, officially Chapter 8, § 8-8 of the City of Boston Code, regulates the short-term rental market to protect the city's housing stock for long-term residents. It defines a short-term rental as a stay of 28 days or fewer and mandates that only owner-occupants or tenants in their primary residence can operate them.

The ordinance prohibits the rental of investment properties and secondary homes. It also established a public registry for all STR units and requires hosts to renew their registration annually.

How it works

To operate a short-term rental in Boston, a host must first verify their eligibility, confirming the property is their primary residence. The ordinance classifies eligible units into three types: Home Share (renting a room while present), Limited Share (renting the entire home while absent, capped at 90 nights/year), and Owner-Adjacent (renting a full unit in a 2- or 3-family building where the owner resides).

The host must then apply to the city for a registration number. This number must be prominently displayed on every online listing for the property on platforms like Airbnb, Vrbo, and others.

Booking platforms are required to share data with the city and remove any listings that lack a valid registration number.

Why it matters

This ordinance fundamentally changes who can participate in Boston's short-term rental market. It effectively eliminates the ability for non-resident investors to operate properties solely for STR purposes.

For eligible hosts, compliance is non-negotiable; operating without a valid and displayed registration number can lead to significant daily fines and removal from booking platforms. Understanding these regulations is crucial for any property owner or manager wishing to legally offer short-term stays in Boston.

Examples

  • A tenant in South Boston rents out their spare bedroom to tourists while they are present in the apartment. This qualifies as a "Home Share" and is allowed, provided they have their landlord's permission and have successfully registered the unit with the city.
  • A homeowner in the North End who lives in their two-family home is prohibited from renting out the second, separate apartment as a short-term rental because it is not their primary residence unit.
  • A condo owner in Back Bay lists their entire primary residence on a booking platform for various weekends when they travel for work. This is a "Limited Share" rental and is permissible as long as they register with the city and do not exceed the 90-night annual rental cap.
  • An investor purchases a studio apartment in Beacon Hill with the sole intention of using it as a full-time Airbnb. This is illegal under the ordinance, as the property is not the owner's primary residence.

Frequently asked questions

Can I rent out a second home I own in Boston as a short-term rental?+
No. The Boston Short-Term Rental Ordinance strictly requires that the unit being rented is the host's designated primary residence. Investment properties and secondary homes are not eligible for short-term rental registration.
What happens if I don't register my short-term rental in Boston?+
Operating an unregistered short-term rental is illegal and can result in fines of $300 per violation, per day. Additionally, online travel agencies (OTAs) are required by law to delist any Boston property that does not display a valid registration number.
Are there limits on how many nights I can rent my primary residence in Boston?+
Yes, if you are renting your entire unit. Under the "Limited Share" category, hosts may rent out their entire primary residence for a maximum of 90 nights per calendar year. There is no annual cap for "Home Share" rentals, where the host is present during the stay.
Do I need to collect special taxes for my Boston short-term rental?+
Yes. Short-term rentals in Boston are subject to the state's 5.7% rooms tax, a local option excise tax of 6.5%, and a 2.75% convention center financing fee. Most major booking platforms collect and remit these taxes on behalf of the host.
