Do you need a shed permit in Massachusetts?

In Massachusetts, you usually don’t need a building permit for sheds up to 200 sq. ft., as long as they’re one story and not used for living space. But that doesn’t mean you’re off the hook because local zoning laws still apply and can affect placement, height, and setbacks.

For sheds over 200 sq. ft., a building permit is typically required. Some towns may have stricter rules, so it’s always best to check with your local building department before starting your project. Skipping this step can lead to fines or delays.

What Size Shed Can I Build Without a Permit in MA?

In Massachusetts, you can usually build a shed up to 200 square feet without needing a building permit, as long as it’s one story and not used for living space. This is allowed under the state building code.

However, zoning rules still apply no matter the shed size. Local regulations may restrict how close your shed can be to property lines, how tall it can be, or where it’s placed on your lot.

If your shed is larger than 200 square feet, you’ll most likely need a permit, and some towns may have stricter thresholds. Always check with your local building or zoning department before starting your project to avoid any fines or delays.

Do I Need a Permit to Run Electricity to My Shed in MA?

Yes, you need a permit to run electricity to your shed in Massachusetts. Even if the shed itself doesn’t require a building permit, any new electrical work must be permitted under the Massachusetts Electrical Code.

In most cases, a licensed electrician is required to pull the permit and perform the work. The permit is filed through your town’s electrical inspector, and the project must pass inspection before the power can be turned on.

This step ensures everything is installed safely and up to code, helping you avoid hazards, fines, or failed inspections down the road.

Shed Permit Requirements in Massachusetts Counties

Whether or not you need a permit often depends on your shed’s size, height, and location on the property. While the state exempts one-story sheds up to 200 square feet from needing a building permit, many towns still require zoning approval or a plot plan, even for smaller structures.

It’s also important to consider things like setback requirements, neighborhood restrictions, and conservation rules that may affect where and how you can build. To help you plan ahead, we’ve gathered an overview of what some Massachusetts municipalities require when it comes to shed permits.

Where do I get a shed permit in MA? 

In Massachusetts, shed permits are typically handled at the local level by the city or town’s building department or inspectional services department where the shed will be built. Massachusetts does not have a statewide shed permit process, so requirements (like size limits, setbacks, and zoning rules) can vary by municipality.

Here’s how to get your shed permit in MA:

1. Visit your town or city’s official website.
2. Look for the Building Department or Inspectional Services section.
3. Download the shed/building permit application or apply online via a portal (some towns use PermitEyes or OpenGov).
4. Submit your shed specs, a plot plan, and pay the fee.
5. Wait for approval before starting any construction.

Even small sheds (under 200 sq ft) may still need a zoning review or site plan approval, depending on your town’s regulations. Always check with your local office to avoid fines or project delays.

How much is a shed permit in Massachusetts?

For smaller sheds (typically under 200 sq ft), many towns charge a modest flat fee, often between $25 and $75. Larger structures or those requiring a full building permit can cost $100 to $200 or more, especially if zoning reviews or inspections are involved. Some towns also base the permit fee on the total construction cost, charging a set rate per $1,000 of estimated value.

Since each municipality sets its own rates, it’s best to check with your local building department for the most accurate pricing.

How long does it take to get a permit in Massachusetts? 

The time it takes to get a shed permit in Massachusetts depends on your town and the complexity of the project.

For smaller sheds (under 200 sq ft), many towns offer quick approval within a few business days, especially if your application is complete and meets local zoning rules. Larger or more complex builds that require full building permits, inspections, or zoning board review can take 1 to 4 weeks or longer.

To avoid delays, submit all required documents (like a site plan and shed specs) up front and double-check local guidelines with your town’s building department.

How long does a building permit last in Massachusetts?

In Massachusetts, a building permit is typically valid for 6 months from the date of issuance. However, this can vary slightly by town.

Most municipalities follow the Massachusetts State Building Code, which allows permits to remain active as long as work begins within 6 months and continues without significant interruption. If your project stalls, you may need to request an extension or reapply, depending on how much time has passed.

For the most accurate timeline, it’s best to check directly with your local building department as they can clarify expiration policies and extension procedures specific to your area.

What is the penalty for not getting a shed permit?

Penalties vary by town, but common consequences include fines, stop-work orders, and mandatory removal of the unpermitted structure. Some municipalities may also charge double permit fees if you’re caught building without prior approval. In worst-case scenarios, you might have to tear down the shed entirely or pay for retroactive inspections and zoning adjustments.

To avoid delays, extra costs, or legal trouble, it’s always best to check with your local building or zoning department before starting your shed project.

Shed Permit Requirements in Massachusetts

In Massachusetts, shed permit rules depend on your local town or city. While some towns allow smaller sheds that are usually under 120 to 200 square feet, without a building permit, zoning approval is still almost always required.

If your shed exceeds the size limit or includes electricity, plumbing, or is placed too close to property lines, you’ll likely need a full building permit and a site plan. Even if a building permit isn’t needed, setback rules, height restrictions, and other zoning laws still apply.

To avoid fines or delays, check with your local building department before starting any shed project.

Ready For Your Shed?

Ready to add a shed to your Massachusetts property? Before you break ground, make sure you’re clear on local permitting rules. In the Bay State, building codes and zoning regulations vary by town, and whether or not you need a permit depends on things like square footage, shed height, and where it’s going on your lot. Skipping this step can cost you, not just in fines, but possibly in having to dismantle your new shed.
