How to Build a Shed on Nantucket: Permits, Process & Pro Tips
Thinking about adding a shed to your Nantucket property? On-island, sheds aren’t just for storage—they’re an extension of your home’s style and character. Prefab sheds may seem convenient at first glance, but custom stick-built sheds, thoughtfully designed and constructed on site, are the preferred option. They integrate beautifully with your home, are more likely to meet HDC requirements, and are built to withstand Nantucket’s coastal environment. J.Martinson Builders can provide drawings and HDC representation as part of your shed building project. Feel free to contact us directly for personalized advice. Want to learn more?

1. Determine if your shed needs a building permit
On Nantucket, sheds under 200 square feet—such as a 10’x20’ or 12’x16’—typically do not require a building permit if they are for storage only and do not include utilities or living space. However, zoning compliance and Historic District Commission (HDC) approval are still required for all sheds, regardless of size or construction method.
A building permit is NOT required if:
• The shed is 200 square feet or smaller
• There are no electrical, plumbing, or HVAC system
• The structure is single-story and used for storage only
A building permit is required if:
• The shed’s ground cover exceeds 200 square feet
• Utilities are included (electric, water, heating/cooling)
• You are looking to add features such as a deck or roof overhang
2. Review Zoning Setbacks & Lot Coverage
Zoning rules on Nantucket are precise and can affect the location, size, and height of your shed.
Always confirm:
• Side, rear, and front yard setback requirements
• Maximum allowable lot coverage (sheds up to 200 square feet is generally exempt from lot coverage allowance)
• Height restrictions for accessory structures
You can check your property’s zoning and details using the Nantucket GIS Map.
3. Professional Site Planning and Survey
You may need a land survey if:
• Property lines are unclear or your shed will be close to setback limits
• The HDC or Building Department requests an official site plan
• You are close to the maximum allowed lot coverage
A professional survey ensures accurate placement and protects against costly mistakes.
4. Obtain Historic District Commision (HDC) Approval
Every shed on Nantucket, regardless of size, must be approved by the Historic District Commission. The review process is much more straightforward for custom stick-built designs tailored to Nantucket’s architectural standards. Generally, a homeowner hires an agent to represent their project. J.Martinson Builders can offer this service for small structures like sheds.
Your HDC submission should include:
• A to-scale site plan showing the proposed shed location
• Elevations of all sides of the shed
• The completed HDC application form
• Photographs of your site and neighboring properties with similar features if applicable
5. Applying for a Building Permit
If your shed exceeds 200 square feet or includes utilities, your contractor will submit abuilding permit application to the Nantucket Building Department after obtaining HDC approval.
You’ll need the following to obtain a building permit:
• HDC approval documentation
• Proof of zoning compliance
• Structural drawings
6. CONSTRUCTION & Final Steps
• If a permit is issued, your builder will schedule required inspections at the foundation, framing, and final stages.
• Even if no permit is required, your construction must fully comply with HDC and zoning standards. This is a separate inspection.
• Once your shed is complete, notify the Nantucket Assessor to update your property records, as this may impact your property tax assessment.
