Concord Building Permit Timelines & Delays
Concord issues its own residential building permits through the Code Administration Division of its Community Development Department, consistent with New Hampshire's model where the state sets the I-Codes minimum (RSA 155-A) but reserves permit issuance to municipalities. Applications run through the city's Citizen Self Service portal.
Concord permitting, the figures

What the data shows
Concord issues its own residential building permits through the Code Administration Division of its Community Development Department, consistent with New Hampshire's model where the state sets the code minimum (RSA 155-A) but reserves permit issuance to municipalities (City of Concord).
The city reports measured volume but not speed: its FY2024 Annual Report shows 523 building permits and about $116 million in construction value, plus hundreds of electrical, mechanical, and plumbing permits, with no plan-review turnaround target published (City of Concord FY2024 Annual Report).
Concord enforces the 2021 I-Codes (the statewide base, with the energy code held at the 2018 IECC); see the New Hampshire state guide for the broader standard-versus-enforcement framework (New Hampshire State Building Code).
Downtown projects face an added gate: work in the Concord Historic District requires a Heritage Commission Certificate of Approval before construction, alteration, or demolition, and the Merrimack River floodplain adds elevation and permit requirements (City of Concord).
On the zoning side, Concord adopted interim amendments in 2025 allowing one accessory dwelling unit (attached or detached) by right in districts that permit single-family homes, to comply with New Hampshire's new statewide ADU law (City of Concord, 2025).
Most delay accumulates before technical review
The data points to the same lever everywhere: most delay accumulates before technical review, in completeness and resubmittal cycles. Permittable's Permit Review Diagnostic checks your plans against applicable codes and common reviewer issues before you submit — so your package is more likely to clear on the first pass.
Concord permitting: FAQ
How long does a building permit take in Concord, NH?
Concord does not publish a plan-review turnaround or service target; it reports volume (523 building permits in FY2024) but not processing time (City of Concord FY2024 Annual Report). A 10-to-15-business-day figure circulating online comes from a private permit-expediter, not the city, so it carries no official weight.
Who issues building permits in Concord?
The City of Concord Code Administration Division, within Community Development. New Hampshire reserves permit issuance to municipalities (RSA 155-A) and provides no statewide enforcement, so Concord runs its own permitting through a Citizen Self Service portal (City of Concord).
Does Concord have historic-district review?
Yes. Projects within the Concord Historic District require a Certificate of Approval from the Heritage Commission before any construction, alteration, or demolition, a review layer on top of the building permit (City of Concord Heritage Commission). The Merrimack River floodplain adds separate elevation and permit requirements for riverfront work.
Can I build an ADU in Concord?
Yes, and more easily since 2025. Concord adopted interim zoning amendments allowing one accessory dwelling unit, attached or detached, by right in districts that allow single-family homes, to comply with New Hampshire's revised statewide ADU law effective July 1, 2025 (City of Concord, 2025). This reversed Concord's prior attached-only rule.

Concord publishes no measured plan-review or permit turnaround; the FY2024 figures are volume totals (523 building permits), not per-application speed. A 10-to-15-business-day residential estimate circulating online is from a private permit-expediter, not the city, and is not used here. The 2025 ADU amendments are labeled interim, so exact size caps should be confirmed against the finally adopted ordinance (state law sets a 750-square-foot floor and a 950-square-foot default ceiling).
