Generator noise in Dallas is regulated under both Chapter 30 (general noise) and the zoning code Section 51A-6.102 (environmental performance standards). Generators near residential use are subject to construction-hour restrictions if used on job sites, and general noise standards at all other times.
Portable and standby generators in Dallas are subject to noise regulations under Chapter 30 and Section 51A-6.102 of the Dallas Development Code. Generators used as part of construction activities near residential use must comply with the construction hours in Section 30-2: 7 AM to 7 PM Monday through Friday, and 8 AM to 7 PM on Saturdays and legal holidays. Outside construction contexts, generator noise is regulated under the general nuisance provisions of Chapter 30 and the zoning noise limits of Section 51A-6.102, which prohibit noise exceeding the background level by more than 5 dB(A) or the district limit, whichever is greater. During power outages, emergency generator use is generally permitted but must still comply with reasonable noise standards. Permanent standby generators require proper permitting and must meet setback requirements. The city recommends sound-attenuated enclosures for generators located near property lines.
Generator noise violations may result in fines up to $2,000 for commercial properties under Chapter 30. Residential violations are Class C misdemeanors with fines up to $500. Generators operating during prohibited construction hours face automatic violation under Section 30-2.
