Lynn, MA Building Setbacks & Zoning: Setback Rules (2026)

The Lynn Zone Ordinance, enforced by Inspectional Services, carves the city into fifteen zoning districts shown on the Zoning Map, running from single- and multi-residence districts through business and industrial zones. Its Table of Dimensional Regulations and footnotes set the minimum yard (setback) each parcel must maintain from its front, side, and rear lot lines, and those distances tighten or loosen by district. Dense residential neighborhoods packed with two- and three-family homes carry smaller yards than outlying single-residence areas. Building into a required yard needs a variance from the Lynn Zoning Board of Appeals under the state Zoning Act, MGL c.40A §10, which requires proof of hardship unique to the lot.
