Nantucket's Affordable Housing Plan: New Developments & Programs for Year-Round Living

Nantucket is making significant progress toward solving its affordable housing crisis, with a goal of reaching 8% of its year-round housing stock classified as affordable by the end of 2025. Through new construction projects like the "New Downtown" development, financial assistance programs, and an innovative deed restriction initiative, the island is actively working to provide stable, year-round housing for its workforce and residents, moving closer to compliance with the state's Chapter 40B law.

What is the Current State of Affordable Housing on Nantucket?

For years, the high cost of real estate on Nantucket, driven by seasonal demand and limited inventory, has made year-round living difficult for many residents. The town is currently addressing a significant gap in its Subsidized Housing Inventory (SHI), which is the official list of affordable housing units that count toward state mandates. According to the 2020 U.S. Census, Nantucket has 6,180 year-round housing units. Under Massachusetts General Law Chapter 40B, municipalities are encouraged to have at least 10% of their housing stock be affordable for low- to moderate-income households. This means Nantucket needs 618 affordable units. The town's housing director, Kristie Ferrentella, recently reported that Nantucket has reached 6.55% of this goal and is projected to hit 8% by the end of 2025.

How is the "New Downtown" Development Contributing?

A key project in this effort is the "New Downtown" development on Sparks Avenue. This project will add 32 new housing units to the island's inventory. A critical feature of this development is that eight of the units will be permanently restricted for households earning at or below 80% of the Area Median Income (AMI). Furthermore, all 32 units are eligible for the town's SHI. This strategic approach not only increases the number of available homes but also ensures that a portion remains affordable in perpetuity, directly addressing the need for housing that is accessible to the local workforce.

What Innovative Programs Are Being Introduced?

Beyond new construction, Nantucket is deploying creative tools to preserve existing housing stock. One of the most anticipated initiatives is a new deed restriction program. In this program, the town will compensate homeowners in exchange for placing a legally binding covenant on their property's title. This covenant would require the home to be used as year-round affordable housing, preventing its conversion to a seasonal or short-term rental. This strategy is a direct response to the challenge of preserving existing inventory that might otherwise be lost to the lucrative seasonal market. Based on our experience assessment, such programs can be highly effective in maintaining community character and stability.

What Were the Historical Challenges Identified?

Nantucket's current initiatives are built on years of planning, including a detailed 2021 Housing Production Plan. This plan diagnosed several structural issues:

• Lack of Housing Diversity: The island's stock is predominantly single-family homes, with few multi-family options, limiting choices for smaller households.
• Geographic Concentration: Most diverse housing types are clustered near the town center, creating bottlenecks for those working in outlying areas.
• Seasonal Market Pressure: A high percentage of homes built between 1980 and 2009 catered to seasonal demand, which did little to alleviate affordability for year-round residents. This led to a high housing cost burden, where many residents spend more than 30% of their income on housing.

Nantucket’s multifaceted approach demonstrates a strong commitment to creating a sustainable community for its year-round residents. By combining new construction, financial aid, and pioneering preservation tools, the island is building a foundation for stable and inclusive living beyond the summer season. The progress toward the 8% SHI milestone is a clear indicator that these strategies are gaining traction.
