Richardson's Noise from Specific Sources: The Rules That Matter

Every city handles noise from specific sources a little differently. In Richardson, Texas, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Generator Noise

Key details: Audibility Standard: Subject to general noise ordinance dBA limits. Audibility Standard: Night limits stricter (about 55-60 dBA residential). Requirement: Standby generators need electrical/gas permits. Requirement: Self-test cycles best scheduled midday. Requirement: Mitigation with enclosures and barriers.

Car Alarm Limits

Key details: Continuous Alarms: Continuous alarms treated as unreasonable noise. Expected Self-deactivation: Expected self-deactivation within 5-10 minutes. Police May: Police may tow repeat offenders. Citations To: Citations to vehicle owner possible. Nighttime Noise: Nighttime noise limits apply.

Bar & Nightclub Noise

Bars, restaurants, and nightclubs in Richardson must comply with the general noise ordinance at receiving property lines and with any conditions in their zoning or specific-use permit. Amplified outdoor sound is tightly regulated in mixed-use areas.

Sup Revocation Possible: SUP revocation possible for repeat violations. Sound Management Plans: Sound management plans recommended.

This is not one of those rules that cities tend to ignore. Richardson actively enforces its bar & nightclub noise requirements.

HVAC & Mechanical Noise

Richardson regulates HVAC equipment noise under its general noise ordinance, which sets dBA limits at the property line that vary by zone and time of day. New equipment installations must be sited to comply with these limits, especially at night in residential areas.

Key details: Noise Ordinance: Noise ordinance applies to HVAC equipment. Residential Daytime: Residential daytime about 60-65 dBA at property line. Lower Nighttime: Lower nighttime limits (55-60 dBA). Complaints Investigated: Complaints investigated with dBA meter. Mitigation: Mitigation: blanket, barrier, relocation, upgrade.

The Bottom Line

Richardson's noise from specific sources rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Richardson is broadly strict or permissive.
