Summary

Seminole County's Land Development Code (Sec. 30.1302) sets maximum sound levels measured at the property line, using octave-band decibel limits that fall from 68 dB at 31.5 Hz to 17 dB at 8,000 Hz along a residential boundary, and higher limits along commercial/industrial boundaries.

These county ordinances apply to unincorporated areas of Seminole County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

Sound levels may be measured at any point on the property line on which the use is located with a sound-level meter and associated octave-band filter manufactured according to standards prescribed by The American Standards Association.

Full Breakdown

Unlike the complaint-based noise Chapter 165, the Land Development Code imposes numeric performance standards. Sec. 30.1302 requires every use to comply with maximum noise standards measured at the property line with a sound-level meter and octave-band filter. Along a property line abutting a residential district the limits by center frequency are: 31.5 Hz = 68 dB, 63 Hz = 66 dB, 125 Hz = 66 dB, 250 Hz = 59 dB, 500 Hz = 52 dB, 1,000 Hz = 46 dB, 2,000 Hz = 37 dB, 4,000 Hz = 26 dB, 8,000 Hz = 17 dB. Limits along a commercial/industrial boundary are higher. Under Ch. 165, officers measure noise with hearing within 20 dB of normal (165.11).

Violations & Fines

Land Development Code noise-standard violations are enforced through county code-enforcement / Chapter 53 procedures; noise-ordinance violations are penalized under Sec. 1.8 (165.61).
