Shed Building Permits & Regulations in Boston and Massachusetts and Boston

Updated: Sep 22, 2022

if you live in Massachusetts and want to add certain structures like a shed to your rear yard or the outside space of your home, you will need to get a permit. It’s extremely easy to overlook the requirements for shed building permits and they can be confusing and often misunderstood.

For example, do you need a special permit? Perhaps there are additional permits and regulations you should consider. Maybe you need a construction permit, demolition permit, or foundation permit.

Getting the necessary building permit is essential if you want the work that’s being completed to be correct and safe. If you want to build certain constructions on your land, completing the work without first filing an application would be unlawful and illegal. There are, however, certain constructions that are exempt from building permits.

In this post, you’ll find out what a shed building permit is, whether you need one, how to get a shed permit, exemptions from the regulations, and much more.

What is a Shed Building Permit?

If you want to build any kind of structure on your land, whether it’s in a residential area or farmland, a building permit may be required.

A shed building permit is something that permits you to do construction work on your property. The permit helps you with meeting local codes and ensures the work is done safely. When you apply for your shed building permit, you need to have your shed plans ready.

Do You Need a Building Permit for a Shed in Massachusetts?

According to the Massachusetts State Building Code (9th Edition), Section 105, if the structure you’re building is going to be used as a storage or tool shed, playhouse, or something similar, a building permit is not required, providing the floor area is no more than two hundred (200) square feet.

In addition, the Massachusetts State Building Code (CMR 780) requires any structure over six hundred (600) square feet to have footings.

There will also be zoning requirements you’ll need to comply with, depending on the district in which you live.

For example, in the DN, MSR, GR, and RC Districts, structures of less than 120 square feet and only one story in height must be five feet from the property line.

If the structure is more than 120 square feet, you’ll need to follow rear yard setbacks for the zoning district where the structure is located.

Do I Need a Permit for a Shed in Boston?

Massachusetts State Building Code (780 CMR, Section R105) states that a permit is not needed to build a one-story detached building, such as a shed, provided the floor area is not more than 120 square feet.

However, the state building code does allow individual municipalities to enact stricter codes, so you must check directly with your city or town building department.

For example, there is a new South Boston Zoning Regulation amendment, Article 27S - South Boston Interim Planning Overlay District. You now need a long-form permit application if the structure you want to build is greater than 1,000 square feet.

The application will go before the Zoning Board of Appeal. If the structure is less than one thousand square feet, a notarized statement from the owner or contractor stating the exact square footage is a requirement.
