Concord Permit Guide

Concord is the state capital, which puts a line through its map that no other New Hampshire city has: the State House and the state office buildings are permitted by the State Fire Marshal, and everything else on Green Street is the city's Building Safety Division.

Derry Permit Guide

Derry takes permit applications online only, and since twenty twenty-two it has required every proof and plan to be in hand before an application is submitted at all — a rule the town adopted specifically so its inspectors could work on complete files.

Dover Permit Guide

Dover runs the most complete online permitting operation in the band — around sixty application types in one portal, available around the clock — and its Inspection Services division moved out of City Hall to a new office on Mast Road in June twenty twenty-five, which catches out anyone working from an older address.

Keene Permit Guide

Keene combines roles that most cities separate: its Building and Health Official is also the city's fire marshal, and its Building Division Manager is also the floodplain administrator and assistant emergency management director — three questions, one person, in a city where the floodplain is the defining constraint.

Merrimack Permit Guide

Merrimack is a town, a river and a county in New Hampshire, and only one of the three is this jurisdiction: the Town of Merrimack sits in Hillsborough County, not in the county that shares its name, and its Building Department works from the Daniel Webster Highway rather than Town Hall.

Nashua Permit Guide

Nashua does not run a permit portal: its Building Safety Department publishes fillable PDF forms, and the completed form is emailed to the department's permits address or brought to a permit desk that closes half an hour before the office does.

Portsmouth Permit Guide

Portsmouth is the smallest city in the band and the most demanding to permit in: the Historic District Commission meets once a month and adds at least that to a review, and the city will not issue a new permit on a property that still has an uninspected one open.

Rochester Permit Guide

Rochester put building, zoning and licensing into a single department rather than splitting them, so the office that answers a setback question is the same one that issues the electrical permit and the business licence.

Salem Permit Guide

Salem sits directly on the state line at the busiest crossing in New Hampshire, which makes it a retail and commercial market far larger than its thirty-two thousand residents suggest — and puts a completely different code framework a few hundred yards from most of its commercial frontage.
