Raleigh, NC Noise Ordinances: Decibel Limits (2026)

Raleigh measures noise using a calibrated Type 2 sound-level meter set to A-weighting and slow response, held at the receiving property line or at the facade of the receiving residence if the property line is too close to the source to produce a representative reading. The exact limits vary by receiving-zone category and time of day, with daytime running from 7:00 AM to 10:00 PM and nighttime from 10:00 PM to 7:00 AM. Residential Receiving Land (R-1, R-2, R-4, R-6, R-10, and residential mixed-use zones) is the most strictly protected, with daytime caps around 60 dB(A) and nighttime caps around 50 dB(A). Commercial and mixed-use receiving zones sit roughly 5 dB(A) higher each, and industrial receiving zones another 5 to 10 dB(A) higher. Short peak noises - impulse sounds such as a backup beeper, a single dropped dumpster, or a gunshot at a shooting range - may have separate peak-value limits measured with a faster time response.

The ordinance also includes a plainly audible standard that allows officers to cite noise without a meter reading when amplified sound - music, bass, public-address systems, or vehicle stereos - is clearly audible across a property boundary during nighttime hours. This is frequently used for downtown Glenwood South bar patios, backyard parties in North Hills and Five Points, and car-stereo complaints along Capital Boulevard, Peace Street, and South Saunders Street. For festivals and permitted events such as IBMA World of Bluegrass, Hopscotch, Brewgaloo, the African American Cultural Festival, and amplified performances at Red Hat Amphitheater and Coastal Credit Union Music Park at Walnut Creek, the city issues special-event noise permits that raise the cap for a limited time and a defined geographic area. Violations typically result in a civil citation for the first offense and escalating penalties for repeat offenses at the same address, with revocation of amplified-entertainment permits a possible consequence for venues.
