Full Breakdown

County Code section 22.02.008 bars operating any musical instrument, speaker, or loudspeaker so it is plainly audible across a property line between 9 p.m. and 8 a.m., and separately bans any noise that exceeds the ambient level by 10 dBA at the point of complaint regardless of time. The Department of Land Use can grant a special waiver for parades, permitted temporary events, or other planned gatherings. Police enforce the ordinance; a first conviction carries a $250-$1,000 fine, rising to $500-$2,500 for a second offense and $1,000-$5,000 for each offense after that, with each day a separate violation. Wilmington and Newark run their own noise codes outside this chapter.

Violations & Fines

First offense: $250 to $1,000. Second offense: $500 to $2,500. Third and later offenses: $1,000 to $5,000 each, and each day the violation continues is a separate offense.

Frequently Asked Questions

Can I play amplified outdoor music after 9 p.m. in New Castle County?
Not if it is plainly audible across your property line. Code 22.02.008.B.2.b bars a loudspeaker or instrument used that way between 9 p.m. and 8 a.m. Daytime music can still violate it if it exceeds ambient noise by 10 dBA.
Does this rule cover Wilmington or Newark?
No. Wilmington and Newark are incorporated cities that run their own municipal codes, which are not part of this county code. This provision governs the rest of New Castle County.
Is there any way to get an outdoor concert or event approved?
Yes. The Department of Land Use can grant a special waiver for a specific event on written application, weighing the hardship of compliance against the impact on neighboring properties.
