Washington County, Vermont Building Permit Guide

Vermont counties have no permitting office, so in Washington County permits come from the town or city, or from the state. By the Census Bureau’s 2025 estimates the largest municipalities are Barre City (8214), Barre Town (8001), Montpelier (7823) and Northfield (5873).

This guide covers the four largest municipalities and the state offices for Washington County.

What requires a permit in Washington County?

In Washington County, permits come from the town or city, under its own zoning and, where it has one, its own building ordinance. Public buildings, which in Vermont include rentals and commercial buildings, also need a state construction permit from the Division of Fire Safety, unless the town enforces the state code itself under an agreement.

Barre Town, for example, requires a building permit for structures greater than 64 sq ft that stay on the property at least 6 months a year.

Vermont has no statewide building code for an owner-occupied single-family home. The state code covers public buildings, including rented homes, and each town decides whether it runs a building department or only issues zoning permits. Vermont rules

Local rules in the largest Washington County towns

Barre City

All development in the city needs a permit, usually some mix of zoning, building, flood hazard and electrical permits. A building permit application is complete only after the Fire Department’s Code Enforcement Office plan reviewer approves it. General maintenance and like-for-like roof, door and window replacement in the same rough opening need no building permit. The city requires its own electrical permit for any electrical work, even by an owner-occupant.

Barre Town

Planning and Zoning issues zoning permits and certificates of occupancy. Before a certificate of occupancy, an RBES or CBES energy certificate must be filed in the Barre Town Land Records.

Montpelier

The city has its own Building Inspector, and building permits apply to all new construction and alterations, including single-family homes, under the Vermont Fire and Building Safety Code, 2025 plus Chapter 4 of the city ordinances. Every project needs one Development Application plus the attachments for each permit; complete applications that need no board review are typically issued within 1-2 business days. Credit cards are not accepted in the office. Public Works permits are needed for new water or sewer connections, adding a bedroom, or work in a city right-of-way.

Northfield

A part-time Zoning Administrator handles permits; a driveway permit is $120.
