Industrial Noise: Apex vs Cary

Are there decibel limits for industrial sites in Apex?

Yes. Apex Town Code Sec. 14-31 (Chapter 14, Article III) sets dB(A) caps in Table 1 that apply at the property line to all sound sources - including industrial sites - with separate daytime and nighttime limits and a violation triggered when sound exceeds the limit for more than ten percent of the measuring period. Sec. 14-30 requires measurement at least 10 feet inside the complainant's property boundary. The Apex Unified Development Ordinance adds buffer-yard, setback, and screening requirements at the boundary between LI (Light Industrial) / TF (Tech/Flex) zones and adjacent residential parcels.

What if industrial noise from the U.S. 1 corridor reaches my neighborhood?

Industrial sites in Apex's LI (Light Industrial) and TF (Tech/Flex) zoning districts must meet the Sec. 14-31 Table 1 dB(A) caps at your residential property line. Call Apex Police non-emergency at 919-362-8661 to report active noise - it can be cited under Sec. 14-31 (sound-emission violation) or Sec. 14-33 (prohibited noise) as a misdemeanor under N.C.G.S. 14-4. For pattern issues, contact Apex Planning - the project's original site-plan conditional approval and Unified Development Ordinance buffer-yard requirements may contain enforceable noise / screening conditions.

How is industrial noise measured?

For sites under UDO Article 7 performance standards, by dBA at the property line per ANSI standards. For others, by the §92 reasonable-person standard.

Can a 24-hour gas station operate?

Yes if not in a residential district. §92.05(L) only restricts garages and filling stations in residential districts during nighttime hours.

Who do I call about a noisy HVAC unit next door?

If commercial: Wake County Sheriff for citation, plus Planning for UDO compliance check. If residential: Sheriff for noise; commercial-grade equipment may still be subject to performance review.
