Commercial and industrial property in Union City may not produce noise more than 12 dBA above the local ambient at the property line, and the City can require noise inventories and reduction plans from non-compliant sources.
UCMC 9.40.042 caps commercial or industrial noise at 12 dBA over the local ambient at any point outside the property line, with ambient never deemed below 40 dBA (9.40.030(D)). Non-complying sources must give the Planning Department a noise inventory and a noise reduction plan (9.40.090) and may have to fund acoustical-consultant reports (9.40.091). The Planning Commission can order cost-effective reduction measures after a hearing (9.40.092), and operations producing a disturbance must cease within 90 days of a decision unless a compliance agreement is executed (9.40.094). New or altered equipment can seek a certificate of compliance before installation (9.40.110-9.40.111). Short-term exceptions are available by permit for up to six months (9.40.060).
Exceeding the commercial/industrial limit is an infraction under UCMC 9.40.121, each day a separate offense; persistent sources face nuisance abatement (9.40.122) and forced reduction under Article 9.
