Newburyport Bylaw Consistency
Newburyport Zoning Ordinance, Section XXII — Accessory Dwelling Units · Last updated January 2025 (adopted January 27, 2025)
Last reviewed: February 23, 2026
What This Means
Newburyport adopted a new ADU ordinance in January 2025 that is among the most consistent in the state. By-right approval, no owner-occupancy requirement, and correct size caps. Two areas merit review: the STR prohibition extends to the principal dwelling, and the Zoning Determination process adds a procedural step beyond a standard building permit.
