The 14-Month Countdown: Plymouth Proactively Chases 10% Affordable Housing Milestone to Block Hostile Developers
PLYMOUTH - June 30, 2026 - The Plymouth Select Board has authorized a comprehensive, proactive strategy to permit 238 affordable housing units within the next 14 months. The aggressive timeline is explicitly designed to maximize the town’s leverage under state law, pushing Plymouth past the critical 10% Subsidized Housing Inventory (SHI) threshold. Reaching this legal milestone will grant the community long-term protection from “hostile” Chapter 40B developments that bypass local zoning bylaws and force density into ill-equipped neighborhoods.
The Full Story
The decision came following a detailed strategic briefing by Assistant Town Manager Lauren Lind, who mapped out the municipality’s current housing metrics and projected growth. Plymouth currently sits at an official SHI rating of 8.42%, requiring 406 units to achieve the state’s 10% compliance threshold. While the town currently features 168 units actively moving through its developmental pipeline, an additional 238 units must be formally permitted before next summer to solidify safe harbor rules permanently through the next census cycle.
“Meeting the 10% gives you the opportunity to then really put aside the threat of a comprehensive permit that you don’t want to see so that you can focus on things like workforce housing... It gives you time on the horizon to proactively plan and put the zoning in that you want.” [03:14:27] — Assistant Town Manager Lauren Lind
The board debated whether to achieve the numbers via public-private partnerships or by utilizing the unique mechanisms of municipal authorities. Select Board member Kevin Canty argued strongly against using the local housing or redevelopment authorities, noting that historical projects, such as the Oak Street School, suffered from structural inefficiencies and inflated costs tied to prevailing wage laws. Instead, Canty urged the town to lean heavily on friendly Chapter 40B comprehensive permits and targeted public-private initiatives, such as deploying Community Preservation Committee (CPC) or Affordable Housing Trust funds to “buy down” deed restrictions on market-rate units already under construction.
