Portable and standby generators in Richardson must operate within the city's noise ordinance decibel limits, which are stricter at night and in residential zones. Permanent standby installations also require a building permit and setback compliance.
Portable generators used temporarily during power outages are generally tolerated but must still avoid creating an unreasonable noise disturbance, especially between 10 p.m. and 7 a.m. in residential zones where the ordinance limit is lower (typically 55-60 dBA at the property line). Generators used for construction or events must operate within the ordinance unless a noise variance has been issued. Permanent whole-house standby generators (such as Generac and Kohler units) require an electrical permit, gas permit, and placement that meets the manufacturer's clearance and the noise ordinance at the property line. Weekly self-test cycles should be scheduled during midday to avoid neighbor complaints. Mitigation options include sound-attenuating enclosures, acoustic barriers, and siting further from bedrooms. Code enforcement responds to complaints and measures dBA at the receiving property line. Long-running construction generators should include a noise impact plan.
Specific penalty amounts for this ordinance are not published in a publicly accessible fine schedule. Contact Richardson code enforcement directly for current fines, enforcement procedures, and hearing options.
