What does a contractor or trade need in Dover that other businesses do not?
4 of the 4 permits particular to a contractor or trade here apply to no other business type we cover in Dover: City of Dover Business License — Contractor, Contractor Business License, Plumbing or HVACR License and Electrician License.
City of Dover Business License — Contractor
This City license is layered on top of Delaware's own state Contractor Business License ($75.00/year, listed on the Delaware state page). Electrical and plumbing contractors specifically must submit a copy of their current State of Delaware professional license and a certificate of insurance for the business as part of this City application — a further local documentation requirement on top of Delaware's own state Board of Electrical Examiners and Board of Plumbing/HVACR Examiners licenses.
Contractor Business License
Contractors license through the same Division of Revenue business license system as any other business, at the identical $75 base rate. A non-resident contractor faces an additional requirement the rest of this license category does not: registering with the Department of Labor's Industrial Accident Board before a license issues, and posting a bond, cash bond or letter of credit equal to 6% of the contract amount.
Plumbing or HVACR License
Delaware licenses plumbing and HVACR work under a single combined board rather than two separate ones, and prices a Master Plumber and a Master HVACR license identically at $173. Unlike most licenses here, there is no grace period at all past the one-year lapse window — the license simply terminates.
Electrician License
A Master Electrician's $203 license costs roughly twice a Journeyperson's or Residential Electrician's $105, on a shared two-year cycle expiring every even year. Continuing education runs alongside it — 10 hours per cycle for Master and Limited license holders, 5 hours for Journeyperson and Residential.
The other 3 local permits in the tables apply to every type of business in Dover, DE; what each one involves is set out on the Dover permits page. The 5 state-level registrations apply to every type of business across DE and are covered on the DE state page.
