This page is general information, not legal advice. Bond amounts are set by New Castle County, and every application is reviewed before a bond is issued. See our disclaimer.

Which trade needs which bond

New Castle County requires bonds for building contractors and for trades that work on gas, water, waste and utility systems. Plumbers, HVAC contractors, gas fitters, septic tank contractors and utility contractors each file the bond for their trade. These are county bonds, separate from any bond the City of New Castle requires.

What the bond does

These compliance bonds run to New Castle County. They back the contractor's promise to follow county land use and building rules. If a contractor breaks those rules and causes a loss, a claim can be paid, and the contractor repays the surety.
