Noise Ordinances in Durham, NC: What Residents Actually Need to Know

If you live in Durham or are thinking about moving there, noise ordinances are one of those things you probably won't think about until they affect you directly. Durham has 9 specific rules on the books covering different aspects of noise ordinances, and some of them might surprise you.

Aircraft Noise

Durham is affected by RDU Airport flight paths 15 miles southeast. Federal law (ANCA) preempts local regulation, but RDU runs a voluntary noise abatement program established in 1989.

Aircraft noise is federally regulated and not subject to Durham municipal noise citations. RDU tracks noise complaints through its online system.
