Delaware contractor license requirements, at a glance
Delaware requires contractors working in the state to register with the Office of Contractor Registration.

Full Delaware licensing detail, local jurisdictions, and official sources
Licensing, bond, and insurance details
| Requirement | Detail | Source |
|---|---|---|
| Surety bond | Delaware does not require a routine surety bond from every registered contractor or Master Plumber. The Department may impose a registration-compliance bond after specified labor-law violations, up to $10,000 per worker. Certain nonresident contractors separately file the Division of Revenue tax bond or approved security. Public work and local permits can impose other bonds. | State source |
| General liability insurance | Delaware contractor registration requires workers-compensation proof when applicable but does not publish a universal commercial general-liability minimum. The current Master Plumber requirements likewise do not list a general-liability minimum. Electrical contractors separately carry at least $300,000 general liability, and a project, owner, municipality, or other trade license can impose additional coverage. | State source |

How to start a contracting business in Delaware
To start a contracting business in Delaware, set up your business entity, register for the state tax accounts that apply to your work, confirm the contractor credential your trade requires with Delaware Office of Contractor Registration, and clear local permits before you hire or bid. Use the ordered steps below as a planning path and open each official Delaware link to confirm what applies to your entity, trade, project size, and job location.
Choose the business structure
Compare the entity options available in Delaware before you file. Your structure affects registration, taxes, ownership records, and the documents a licensing agency may request.
Register the business
Use the official Delaware filing system to form or register the entity and confirm whether a separate business name filing is needed.
Set up state tax accounts
Check the state revenue agency for business tax registration, sales or marketplace tax rules, withholding, and any industry-specific accounts that apply to your work.
Confirm the contractor credential
Start with Delaware Office of Contractor Registration. Match the license, registration, classification, or local requirement to the exact trade and scope you plan to sell.

Check permits and local rules
State registration does not replace city, county, building-department, or trade-permit rules. Confirm the job address and scope before bidding or starting work.
Register before hiring
If you will have employees, confirm employer registration, withholding, unemployment, workers compensation, and workplace-safety responsibilities with the responsible agencies.

What to verify before you bid
Before you bid in Delaware, confirm the credential matches the exact work and that your business, tax, and insurance records use the same legal name. A state license or registration does not replace city or county permits, local business licensing, or bond requirements, so verify the job location too.
- Match the credential to the work. General building, residential work, electrical, plumbing, HVAC, roofing, public work, and specialty trades can follow different rules.
- Check the project location. A state registration never replaces city or county contractor registration, permits, bond requirements, or local business licensing.
- Set up the business first when required. Confirm the entity name, tax account, workers' compensation status, and insurance certificate match the name used on the license application and contracts.
- Confirm money and deadlines directly. Fees, financial limits, bonds, insurance minimums, renewal dates, notice rules, and lien deadlines are deliberately omitted unless they were checked against the responsible agency or statute.

Common Delaware contractor startup questions
Does Delaware require a contractor license?
Delaware requires contractors working in the state to register with the Office of Contractor Registration. Business licensing, tax accounts, and nonresident-contractor rules are separate and may apply in addition to trade and local requirements.
Where do I start the contractor application?
Start with Delaware Office of Contractor Registration (DOCR). Confirm the classification and application path for your exact work before relying on a general summary.
