Full Breakdown

Apex's noise chapter singles out stationary engines by name: discharging engine exhaust into the open air without a muffler is 'plainly audible and unreasonably loud' by definition under Town Code § 14-33(a)(6), regardless of any decibel reading, a home standby generator, a portable job-site generator, or a stationary steam engine all qualify. A muffler or other device that effectively prevents loud or explosive noise satisfies the rule; no permit is required. The provision sits inside the general noise-prohibition chapter (§§ 14-29 through 14-37), applies within the town's corporate limits, and is enforced as a misdemeanor under G.S. 14-4 with additional civil penalties available under § 14-37.

Violations & Fines

Misdemeanor under G.S. 14-4; civil penalties up to $100/day for the first five days and $500/day thereafter under § 14-37, plus possible town injunctive action for continuing violations.

Frequently Asked Questions

Does Apex set a decibel limit for generator noise?
No. Town Code § 14-33(a)(6) bans unmuffled exhaust from any stationary engine, including generators, outright rather than setting a decibel threshold; a working muffler that prevents loud or explosive noise satisfies the rule.
Can I run a portable generator during a power outage in Apex?
Yes, as long as its exhaust is muffled. The rule targets unmuffled exhaust noise, not generator use itself, and the code's emergency-work exception separately protects outage-related work.
