New Castle County Contractor License: Classes, Bonds, and Application Process
Two License Types, Four Bond Classes
New Castle County requires its own contractor license for work in unincorporated areas — your state business license and DOL registration don't cover it. The county's Department of Land Use issues two types:
Permit Endorsed licenses are for contractors performing structural work that requires building permits (new construction, additions, major renovations). Non-Permit Endorsed licenses cover NAICS Sector 23 contractors doing cosmetic or non-structural work that doesn't trigger a building permit — think painting, flooring, or landscaping.
The distinction matters because Permit Endorsed licensees need statutory compliance bonds and ICC digital code access. Non-Permit Endorsed licensees don't need bonds and pay a scaled fee based on employee count ($150 to $400).
License Classes and Bond Amounts
Permit Endorsed licenses are divided into four classes based on the maximum project valuation you can work on:
| Class | Project Valuation Ceiling | Required Bond |
|---|---|---|
| Class U (Unlimited) | No limit | $200,000 |
| Class A | Up to $200,000 | $150,000 |
| Class B | Up to $100,000 | $50,000 |
| Class C | Up to $50,000 | $25,000 |
The bond must be a New Castle County Statutory Compliance Bond using the exact county-mandated form. Modified or custom bond forms get rejected — the surety company needs to use the county's specific template, and the name on the bond must match the license application exactly.
Annual Fees and the ICC Digital Access Requirement
Every Permit Endorsed contractor pays $400 per year for the license plus a mandatory $10 ICC Digital Code Access Fee — total of $410. The county replaced physical code book sales at permit counters with this digital subscription, which grants discounted online access to the adopted building codes, commentaries, and local amendments.
The $410 fee is the same across all four classes. Your bond premium varies by class and credit history, but the county fee itself doesn't change whether you're Class C or Class U.
Starting July 1, 2026, New Castle County applies a mandatory 3% service fee to all credit card transactions at the Department of Land Use, so factor that in if you're paying licensing or permit fees by card.

What You Need Before Applying
Before submitting your NCC contractor license application, you'll need:
- An active Delaware Division of Revenue business license
- A DOL Contractor Registration Certificate
- General liability insurance (minimum $250,000 per occurrence, $500,000 aggregate)
- Workers' compensation coverage (or documented exemption)
- The completed Statutory Compliance Bond in the county's exact form
- Your Master Contractor License Verification (CLV) form
Applications go through the NCC Department of Land Use eServices Portal. Processing times vary, but having all documents ready and bond forms correctly completed avoids the most common rejection reasons.
Important: NCC Licenses Don't Cover Wilmington or Newark
New Castle County's licensing authority covers unincorporated areas only. If your project is inside the City of Wilmington or the City of Newark, you need their separate municipal contractor licenses and bonds — an NCC permit-endorsed license won't let you pull permits there.
This catches contractors who assume the county license covers everything in the county. Map your project parcel to the correct authority having jurisdiction before applying.
Getting Set Up Across All Jurisdictions
The county license is one piece of a multi-layer system — you also need state registrations and potentially municipal licenses depending on where your projects are. The Delaware General Contractor License Guide walks through the complete sequence from state business license through county permit endorsement, with the exact forms and bond templates referenced for each step.
