Apex FAQ
Is there an HVAC noise limit in Apex, NC?
Apex Town Code does not include an HVAC-specific decibel limit or setback. HVAC noise is enforced under the general Sec. 14-31 Table 1 dB(A) caps at the complainant's property line (measured at least 10 ft inside the boundary per Sec. 14-30, with the violation triggered when the cap is exceeded for more than 10% of the measuring period). Violations are misdemeanors under N.C.G.S. 14-4. Report to Apex Police 919-362-8661.
Where can a new AC condenser be placed on my Apex property?
HVAC equipment placement is not addressed in Town Code Chapter 14 - it is governed by the Apex Unified Development Ordinance for your specific zoning district (typically a minimum side or rear yard setback for accessory mechanical equipment, with stricter rules in buffer yards adjacent to a different zoning district). Permits are issued by Apex Building Inspections & Permitting under the State of North Carolina mechanical code, applied uniformly statewide under N.C.G.S. Ch. 160D-1101. Check your HOA covenants too - Beaver Creek, Salem Village, Bella Casa, and similar Apex subdivisions frequently impose stricter equipment-screening rules than the town code.
