Lewiston Maine Fence and ADU Permit Guide

Lewiston requires fence permits and allows accessory dwelling units through building permits under local size, occupancy, and principal-dwelling standards.

Permit takeaway

Lewiston says a fence permit is required and the department needs the proposed fence length and height when the permit is requested.

Zoning and placement

Fence placement may be on the property line, but Lewiston recommends offsetting the fence enough to maintain both sides without crossing onto a neighbor's property.

Building and trade review

New accessory dwelling units may be constructed with a building permit and are limited by the city's ADU standards, including maximum size and owner-occupancy rules.

Call before applying when

Call before applying if the fence will be on a property line, the property is historic or constrained, the ADU is detached, the ADU approaches 900 square feet, or owner-occupancy status is unclear.
