Summary
Oakland County does not set a county-wide dBA limit. Royal Oak Zoning §770-94 caps noise at 75 dBA between 6:00 a.m. and 10:00 p.m. and 60 dBA between 10:00 p.m. and 6:00 a.m., measured at the lot line. Birmingham permits powered equipment up to 100 dBA at the property line between 7 a.m. and 7 p.m. Most other Oakland County jurisdictions (Charter Township of Oakland, Pontiac, Troy, Farmington Hills) use audibility-based standards ("clearly audible at the property line" or "50 feet from boundary") rather than numeric dBA caps.
Noise levels shall not exceed 75 decibels between the hours of 6:00 a.m. and 10:00 p.m. and shall not exceed 60 decibels between the hours of 10:00 p.m. and 6:00 a.m. ... Noise which is objectionable as determined by the City due to intensity, frequency, or duration shall be muffled, attenuated, or otherwise controlled. ... Noise resulting from temporary construction activity shall be exempt from this requirement.
Full Breakdown
Numeric decibel limits in Oakland County are the exception, not the rule. §770-94 also prohibits any objectionable intermittent or high-frequency sound regardless of dBA reading, and exempts public-purpose sirens and temporary construction. operating hours. Charter Township of Oakland, Pontiac, Troy, Farmington Hills, and most townships use plain-language audibility tests ("clearly heard 50 feet from the boundary," "clearly audible beyond the property line") rather than calibrated dBA measurements, which means responding officers do not need sound-level meters and can issue infractions based on lay observation. Several Oakland County cities have separate stationary-source dBA tables in their zoning codes for industrial and commercial zones that are stricter than the residential limits.
Violations & Fines
Violations of Royal Oak §770-94 are enforced through zoning and police citations. Audibility-based ordinances in Pontiac, Troy, Charter Township of Oakland, and Farmington Hills are enforced by responding officers as municipal civil infractions without requiring dBA measurement. Pontiac fines run $50-$500 first offense to $200-$500 for third-plus within two years. Royal Oak treats §770-94 violations as zoning enforcement subject to misdemeanor or civil-infraction prosecution depending on the offense.
