Irving, TX Environmental Rules: Vehicle Idling Restrictions (2026)

Sec. 22-3(a)(12) of the Code of Civil and Criminal Ordinances makes it a per se noise violation to operate the engine of any motor vehicle with a manufacturer's gross weight specification over 10,000 pounds within 300 feet of a residential structure for longer than 15 minutes, unless the vehicle sits inside an enclosed structure. The rule targets heavy trucks, delivery vehicles and similar equipment idling near homes rather than passenger cars. Enforcement runs through Sec. 22-7, which gives the chief of police (or a designee, including code enforcement officers) primary responsibility, and Sec.

22-6 creates a rebuttable presumption that the vehicle's registered owner is the person responsible for an idling violation, provable through Texas Department of Transportation registration records. The idling limit sits alongside the chapter's separate exhaust-muffler requirements in Sec. 22-3(a)(13), which bar discharging exhaust from stationary engines or motor vehicles except through an effective muffler, so a truck that idles legally under the 15-minute limit can still be cited if its exhaust is unmuffled or excessively loud.
