Delaware Contractor Bond Requirements: State, County, and Municipal Bonds Explained
Bonds Layer Up Fast in Delaware
Delaware's decentralized licensing system means surety bond requirements come from multiple authorities. Depending on where you work and what type of work you do, you might need bonds from the state, the county, and the city — each serving a different regulatory purpose.
Understanding which bonds apply to your situation prevents two common problems: paying for bonds you don't actually need, and getting blindsided by a bond requirement mid-project that delays your permit application.
State-Level Bonds
Non-resident contractor bond. If your business is headquartered outside Delaware, the Division of Revenue requires a surety bond equal to 6% of any single contract valued at $20,000 or more, or 6% of combined contracts within a calendar year totaling $20,000 or more. This bond guarantees your tax obligations to the state.
You can also post a cash bond or certificate of deposit instead of a surety bond. The bond must be in place before you begin physical work on any Delaware project.
HICPA bond. Contractors performing residential home improvements above $1,000 must maintain a minimum $10,000 surety bond registered with the Attorney General's Consumer Protection Unit. This applies to all residential contractors — general and specialty trades alike.
New Castle County Bonds
New Castle County requires a Statutory Compliance Bond for all Permit Endorsed contractor licenses. The bond amount matches your license class:
| License 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 |
Two critical details: the bond must be on the exact county-mandated bond form (modified forms are rejected), and the name on the bond must match your license application exactly. A mismatch between your business name on the bond and the name on your application is one of the most common rejection reasons.

City of Newark Bonds
Newark requires a Compliance Bond scaled to estimated construction cost:
| Estimated Construction Cost | Required Bond |
|---|---|
| $1,000,000 and above | $200,000 |
| $500,000 to $999,999 | $150,000 |
| $250,000 to $499,999 | $100,000 |
| $100,000 to $249,999 | $75,000 |
| $25,000 to $75,999.99 | $25,000 |
| Under $25,000 | $10,000 |
Newark's bond carries an unusual feature: it guarantees that you'll correct any code violations discovered within three years of the certificate of occupancy. That's a longer obligation window than most performance bonds, so your surety exposure extends well past project completion.
Newark also requires your certificate of liability insurance to explicitly name the City of Newark as the certificate holder, with limits of $300,000/$500,000 per accident.
City of Wilmington Bonds
Wilmington requires a $3,000 surety bond specifically for contractors performing HVAC, plumbing, and street/sidewalk/utility curb work. This is a trade-specific bond — general contractors doing structural work without those scopes may not need it, but if your project includes any plumbing or mechanical work, the bond applies.
What You Don't Need
Kent County and Dover rely on state-level licensing and trade bonds. They don't impose county-level general contractor bonds. Sussex County doesn't require a general contractor bond either, though it does require a $5,000 trade plumbing bond for licensed plumbers.
Bond Premiums vs. Bond Amounts
The face value of a bond (the penal sum) isn't what you pay out of pocket. You pay a premium to a surety company, and the premium depends on your credit score, financial history, and business track record. A contractor with credit issues could pay substantially more, or need to post collateral.
