How This Compares to Essex County

Lynn's own rule is shown above (No permit under 200 sqft). Here is the separate rule that applies at the county level, for context:

No county-level building department — each town administers

Distinctively, within Essex County itself there is real town-to-town divergence: Hamilton exempts sheds up to 8x12 ft and 10 ft tall (subject to setbacks), while neighboring Gloucester requires a building permit for every shed regardless of size, with structures over 120 sq ft additionally needing to comply with the full state building code. The Town of Essex (a distinct municipality sharing the county's name) also requires permits for most sheds.
