What does a contractor or trade need in Nashua that other businesses do not?
3 of the 3 permits particular to a contractor or trade here apply to no other business type we cover in Nashua: General Contractor Registration (not found), Electrician License and Plumbing License.
General Contractor Registration (not found)
No fee applies. New Hampshire has no statewide general contractor license (confirmed at this project's own state layer), and Nashua's own Department of Building Safety issues building, mechanical, electrical, and plumbing permits per project through the process recorded elsewhere in this file rather than a standing local contractor registration. The City Clerk's own current Licenses & Permits page names no general-contracting category either.
Electrician License
A striking gap between the application fee and the renewal fee: both journeyman and master applications cost the same modest $50, but renewal jumps to $150 for a journeyman and $270 for a master, on a three-year cycle. A high or medium voltage electrician's renewal is also $270. An electrical corporation registering as a business pays a separate $50 application, a $20 certificate fee and $125 to renew.
Plumbing License
Plumbing and mechanical trades sit under one combined board here rather than being split apart, unlike electrical work, which has its own separate board. A master plumber pays $310 to apply and $300 to renew; a journeyman $190 and $180; an apprentice $90 and $80. The same board licenses fuel gas fitting, hearth installation and domestic appliance work as related but distinct credentials, each in a similar $170 to $190 price range, plus a $250 fee for a mechanical business entity registering as a company.
The other 5 local permits in the tables apply to every type of business in Nashua, NH; what each one involves is set out on the Nashua permits page. The 4 state-level registrations apply to every type of business across NH and are covered on the NH state page.
