About this bond

What a subdivision bond is

Cities and counties often require a developer to bond the public improvements in a new subdivision or site plan, like streets, sidewalks, storm drains, sewer and water lines, before they approve the final map or permits. The bond guarantees the improvements are built to the agency's standards.

In Delaware

Delaware's DelDOT requires security before it takes over new subdivision streets for state maintenance, under 17 Del. C. § 508. Since June 9, 2025, the bond is 150% of the top coat cost estimate.

FAQs

Common questions.

How much does the Delaware Subdivision Bond cost?

3% of the contract amount, with a $250 minimum. The calculator on this page works it out for your amount. Propeller adds a $25 service fee for this bond.

Do I have to pay the full bond amount?

No. You pay the premium. The bond amount is the most the surety would pay out on a valid claim, and if it ever pays one, you pay the surety back.

Is there a credit check?

A soft one. Propeller's application asks you to agree to a soft credit inquiry, which doesn't affect your credit score. Your credit can change the rate, and you see the final price before you pay.

Who sets the subdivision bond amount in Delaware?

The city or county approving the subdivision, usually based on the engineer's estimate of the improvement costs. See the facts above for the state law behind it.

When is the bond released?

After the agency accepts the finished improvements. Many agencies then require a smaller maintenance bond for a warranty period.
