Preserving the Island's Character
Understanding the Historic District Commission is essential for any property owner on Nantucket. The HDC process may seem complex at first, but it's what preserves the timeless character that makes this island so special—and protects your investment for generations to come.

Understanding the HDC
The Historic District Commission (HDC) is a five-member elected board established in 1955 that governs all exterior changes to buildings and structures on Nantucket. The entire island, including Tuckernuck and Muskeget, is designated as a National Historic Landmark and listed on the National and State Registers of Historic Places.
The HDC ensures that Nantucket's unique architectural heritage is preserved for future generations. This protection maintains property values and the island's distinctive character that makes it one of the most sought-after destinations in the country.
Any exterior change visible from a public way requires HDC approval. This includes new construction, additions, alterations, paint colors, windows, doors, roofing, fencing, hardscaping, landscaping features, and even equipment like HVAC units.
The HDC issues Certificates of Appropriateness (COA) for approved projects. Applications must include detailed plans, drawings, photographs, and for larger projects, proof of abutter notification. Certificates are valid for three years from issuance.

Frequently Asked Questions
No, the HDC only has jurisdiction over exterior features visible from a public way, including Nantucket Harbor. Interior renovations do not require HDC approval, though they may require building permits.
Simple projects may be approved within a few weeks, while complex renovations or new construction can take several months. The HDC meets every Tuesday at 4:00 PM. Plan for at least one round of revisions before final approval.
Violations result in a penalty of $300 per day until the violation is corrected. The HDC may also require you to restore the property to its previous condition or submit a new application for approval.
The HDC maintains a list of pre-approved historic colors, but they can technically approve any color that fits Nantucket's historic character. Colors should be subdued in hue and blend with adjacent buildings and the overall setting.
For projects involving 1,000 square feet or more of changes (100 square feet in historic core areas), you must notify abutters via certified mail and provide proof with your application.
Highly recommended. Architects experienced with Nantucket's HDC understand the nuances of designing for the island and can save you significant time and money by avoiding common pitfalls in the approval process.
