Hartford County, Connecticut Building Permit Guide

Hartford County is a map label, not a permit office. Connecticut dissolved county government in 1960, so a building permit here comes from the building department of the town where the parcel is. The four largest towns by the Census Bureau’s 2025 estimates are Hartford (121981), New Britain (76286), West Hartford (64242) and Bristol (62341).

This guide lists the towns in Hartford County and the building offices and local rules of its four largest towns.

What requires a building permit in Hartford County?

Hartford County has no county building rules. Whether a job needs a permit is set by the State Building Code, the same in every Connecticut town, and the town adds its own zoning, fees and filing rules, which differ from town to town as the examples below show.

Building, mechanical, plumbing, sprinkler and temporary structure permits are applied for online. Check first whether a Planning and Zoning application is needed and whether the property is in a historic district subject to historic review. The application needs drawings, technical specifications, a workers comp certificate listing the City of Hartford as certificate holder, the contractor’s license and, for home improvement work, the signed contract. The city has up to 30 days to respond to a completed application; typically permits are issued within the first two weeks.

New Britain

Permits come from the Department of Licenses, Permits and Inspections. Inspection requests go through the permit portal, and inspectors keep office hours of 8:15 - 9:30 A.M. and 3:00 - 3:45 P.M.; outside those hours an appointment is required.
