How much does it actually cost to permit a contractor or trade in New Castle County?

What does a contractor or trade need in New Castle County that other businesses do not?
5 of the 5 permits particular to a contractor or trade here apply to no other business type we cover in New Castle County: Permit Endorsed Contractor License (building Class U, A, B, C and utility contractors), Non-Permit Endorsed Contractor License (NAICS Sector 23 work that needs no permit), Contractor Business License and 2 more.
Permit Endorsed Contractor License (building Class U, A, B, C and utility contractors)
The county's Contractor Licensing page states: "Contractors working in unincorporated New Castle County providing construction and building improvement services are required to obtain a New Castle County contractor license." A permit endorsed license "is required for those individuals or companies who perform construction related activities that require a permit. This would include building, plumbing, and HVACR contractors to name a few." Under §6.03.001 each application is accompanied by the fee stated in the Appendix, and the Department sets the policy on expiration and renewal. Chapter 6 Appendix 7 (Miscellaneous Fees Schedule, Eff. 07/01/2009, Rev. 11/30/2010, 07/01/2015) sets $400 per license category for building contractors (Class U, A, B, C) and for utility contractors. The county's 2026 Building Contractor Requirements and 2026 Utility Contractor Requirements sheets state: "The total fee for the 2026 license is $410: License Fee - $400 ICC Digital Code Access Fee - $10"; the ICC fee pays for online access to the adopted codes. Required with the online application: a State of Delaware business license valid for 2026; a certificate of liability insurance with minimum limits of $250,000 per occurrence and $500,000 aggregate; and the county's 2026 Statutory Compliance Bond form (modified forms are not accepted). Bond amounts on the 2026 sheets and the Appendix 4 bond form: Class U $200,000 (unlimited project value), Class A $150,000 (projects up to $200,000), Class B $50,000 (up to $100,000), Class C $25,000 (up to $50,000), HVACR $25,000, Decorative Appliance $10,000, Master Plumber $10,000, Sewer & Drain Cleaner $10,000 and Outside Utility $50,000. New home builders must hold at least Class A, and HVACR and plumbing contractors also need a State of Delaware Division of Professional Regulation license for their trade. The bond form states "License Period: January 1, 2026 to January 1, 2027". New Castle County Code §6.01.001 states that Chapter 6 "shall apply to the unincorporated territory of New Castle County, Delaware, and may apply to incorporated municipalities if by appropriate action of its governing body, any such governing body elects to be included in its application. Such jurisdictions are defined in Appendix 6 of this Chapter." The county's Contractor Licensing page states: "Any properties that are incorporated in a specific property tax area are not New Castle County's jurisdiction." Licensing questions: 302-395-5420, licensing@newcastlede.gov.
Non-Permit Endorsed Contractor License (NAICS Sector 23 work that needs no permit)
The county's Non-Permit Endorsed Contractor License page states that these licenses "are valid to perform construction activity defined by Sector 23 of the North American Industry Classification System (NAICS) code that does not require a permit from our jurisdiction or fall under HVACR and plumbing work." The Contractor Licensing page's FAQ states that "All persons engaging in any aspect of construction activity, as defined by Sector 23 - Construction" of NAICS are contractors requiring a license, excluding those solely engaged in subdivision and land development, electrical contractors (licensed by the State of Delaware as electricians), heavy utility construction in the DelDOT right of way, and maintenance employees of state-owned facilities. The fee depends on the number of employees, as listed on the county's 2026 Contractor License Application for Non-Permit Endorsement Holders and in Chapter 6 Appendix 7 (Eff. 07/01/2009, Rev. 11/30/2010, 07/01/2015): $150 for a business with no employees (sole proprietor) up to five employees, $250 for six to ten, and $400 for eleven or more. The application asks for the State of Delaware business license number, and can be filed online with a credit card or on paper with a check to 87 Reads Way, New Castle, DE 19720 (allow up to two weeks for processing). New Castle County Code §6.01.001 states that Chapter 6 "shall apply to the unincorporated territory of New Castle County, Delaware, and may apply to incorporated municipalities if by appropriate action of its governing body, any such governing body elects to be included in its application. Such jurisdictions are defined in Appendix 6 of this Chapter." The county's Contractor Licensing page states: "Any properties that are incorporated in a specific property tax area are not New Castle County's jurisdiction."
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 2 local permits in the tables apply to every type of business in New Castle County, DE; what each one involves is set out on the New Castle County permits page. The 5 state-level registrations apply to every type of business across DE and are covered on the DE state page.
