Lynn Zoning & Land Use Guide
Key Zoning Facts
Lynn Zoning Overview
Lynn is a diverse coastal city on the North Shore, located about 10 miles north of Boston with direct MBTA commuter rail and bus service. Once a major shoe manufacturing center, Lynn is experiencing a renaissance as rising Boston-area housing costs drive development interest to its waterfront, downtown, and transit-accessible neighborhoods.
The city's zoning is administered by the Office of Economic and Community Development. Lynn's zoning code organizes the city into residential, commercial, and industrial districts, with particular attention to the waterfront and downtown redevelopment areas. The city has adopted several overlay districts to guide mixed-use development along key corridors.
Lynn's waterfront location, transit access, and relatively affordable land values make it a focal point for housing development in the Boston metro area. The 2024 state ADU law and MBTA Communities Act requirements further support the city's housing production goals.
Key Zoning Districts
Lynn's zoning includes R-1 through R-4 residential districts (increasing density), C-1 (Neighborhood Commercial), C-2 (General Commercial), and industrial zones. The Waterfront overlay and Downtown overlay districts allow higher density mixed-use development.
ADU Regulations
Under the 2024 state ADU law, Lynn permits ADUs by right in single-family zones. ADUs may be up to 900 square feet with no additional parking required. The Building Department handles ADU permits within 45 to 75 days.
Development Process
Development in Lynn starts with a zoning review through the OECD. Conforming projects proceed to building permits. Variance and special permit requests go to the Zoning Board of Appeals. Projects in overlay districts may require additional site plan review.
