Design My ShedAdding a shed can give you much-needed storage, workspace, or room for hobbies without making major changes to your home. Before choosing a size and scheduling installation, however, there is one important question to answer: Do I need a permit for a shed?
The answer depends on where you live, the size and use of your shed, and your local zoning requirements. In Massachusetts, certain small sheds may not require a building permit, while larger structures generally do. Requirements can also vary considerably between towns and across New England.
Here’s what homeowners should know before installing a new shed.
Do I Need a Permit for a Shed in Massachusetts?
In Massachusetts, you generally do not need a building permit for a one-story detached shed that is 120 square feet or smaller, provided it is used as a tool shed, storage shed, playhouse, or similar accessory structure. Under the Massachusetts State Building Code, these structures are listed as work exempt from the building permit requirement.
However, that does not automatically mean you can place a 120-square-foot shed anywhere on your property.
Your city or town may have zoning requirements governing accessory structures, including rules related to:
- Property line setbacks
- Distance from your home or other structures
- Maximum shed height
- Lot coverage
- Placement in front, side, or rear yards
- Wetlands or environmentally protected areas
- Easements and rights-of-way
That is why it is always a good idea to contact your local building or zoning department before ordering your shed, even when the shed itself appears to be exempt from a building permit.
How Big Can a Shed Be Without a Permit in Massachusetts?
Under the Massachusetts State Building Code, a one-story detached accessory structure used as a tool or storage shed, playhouse, or similar use can be up to 120 square feet without requiring a building permit.
For example, a typical 10′ x 12′ shed is 120 square feet and may fall within this exemption. A 12′ x 12′ shed, on the other hand, is 144 square feet and exceeds the state building permit exemption.
Keep in mind that the 120-square-foot threshold addresses the state building permit requirement. Local zoning rules can still apply to a shed that does not need a building permit.
If you are considering a larger shed, garage shed, pool house, or another more substantial structure, check with your municipality early in the planning process so you know which approvals will be necessary.
What Are Shed Setback Requirements?
A shed setback is the minimum distance your shed must be located from a property line, street, house, septic system, wetland, or another feature on your property.
There is no single setback distance that applies to every shed throughout Massachusetts or New England. Setback requirements are generally established through local zoning regulations, which means the rules in one town can be different from those in the next town.
For example, your town may allow a small accessory structure relatively close to a rear property line while requiring a larger shed to meet the same setbacks as other structures.
Before deciding exactly where your shed will go, confirm:
- Your property boundaries
- Required front, rear, and side setbacks
- Whether shed size changes the setback requirement
- Whether there are septic, utility, drainage, or wetland restrictions
- Whether an HOA or neighborhood association has additional requirements
This is especially important when you have a smaller backyard where every foot of usable space matters.
Do I Need a Permit for a Shed in New Hampshire?
New Hampshire shed permit requirements depend in part on your municipality and the type of construction involved. New Hampshire law requires permits for construction covered by the state building code, and municipalities that have adopted local enforcement mechanisms administer permits through their locally adopted processes.
Because local requirements can differ, homeowners should check with their city or town before installing a shed. Depending on the project and municipality, you may need to consider building permits, zoning approval, setbacks, size restrictions, or other requirements.
If you are researching New Hampshire shed permits, start with your town or city’s building department and provide the proposed shed dimensions, location, foundation type, and intended use. That information will help the department tell you exactly what is required.
What About Shed Permits in Maine, Vermont, Rhode Island, and Connecticut?
The same general advice applies throughout New England: never assume that the rules in a neighboring town or state apply to your property.
Eastern Shed serves homeowners throughout Massachusetts, New Hampshire, Maine, Vermont, Rhode Island, and Connecticut, and permitting and zoning requirements can vary throughout the region.
Before installation, contact your local municipality and ask:
- Do I need a building permit for a shed of this size?
- Are there separate zoning requirements for accessory structures?
- What are the required shed setbacks?
- Are there maximum height or lot coverage restrictions?
- Do I need to submit a plot plan or site plan?
- Are additional permits required if I add electricity or plumbing?
Getting these answers before finalizing your shed size and location can help prevent delays later in the process.
Do I Need a Permit If My Shed Has Electricity?
Even when the shed itself does not require a building permit, adding electrical, plumbing, heating, or other utilities may trigger separate permit and code requirements.
This is particularly important if you are planning something beyond basic storage, such as a workshop, home office, hobby space, pool house, or golf simulator shed.
Tell your local building department how you intend to use the structure rather than simply asking whether a shed of a particular size requires a permit. The shed’s intended use and features may affect the answer.
Who Is Responsible for Getting a Shed Permit?
For an Eastern Shed installation, the homeowner is responsible for obtaining required building permits and making sure the shed location complies with local setback requirements.
That does not mean you have to figure everything out alone. If your town requires a permit, Eastern Shed can assist with the application process and provide relevant information about your shed.
It is best to investigate permitting early, before installation is scheduled. This gives you time to adjust the shed size, location, or other details if local regulations require changes.
Plan Your Shed Before Installation Day
Permits and setbacks are only part of preparing for a shed. You will also need to choose an appropriate location and make sure the installation area is level, firm, accessible, and clear of obstructions.
