Hudson, NH Building Safety: Plumbing Permits (2026)

Hudson Town Code § 205-2K sets the plumbing permit fee schedule, administered alongside all other building permits by the Community Development Department. A residential plumbing permit is $75, rising to $100 for new construction; a renovation permit is $75, a deduct meter is $60, and a temporary plumbing permit is $75. 01 per square foot beyond that, with a separate $75 deduct-meter fee for commercial accounts. Industrial plumbing work carries a flat $275 fee. As with electrical work, the underlying construction standards come from the codes Hudson has adopted under § 178-1: the 2003 International Residential Code for one- and two-family dwellings, and the current State Building Code under RSA 155-A:1 for all other structures, with the Town declaring under § 178-1C that it will enforce that state code pursuant to RSA 674:51(I).

Demolition permits, listed immediately after plumbing in § 205-2L, run $50 residential, $100 commercial and $175 industrial, underscoring that Hudson treats each trade and phase of construction as its own permitted, fee-bearing step.
