Summary
Martin County caps industrial and commercial noise, including data center HVAC and generator sound, at fixed decibel levels measured at the property line.
Maximum permissible sound levels by receiving land use are set forth in table 1. It shall be unlawful to operate or cause to be operated any source of sound or to project a sound or noise across a real property boundary in such a manner as to create a sound level which exceeds the limits set forth for the receiving land use designation... Industrial: 7:00 a.m.—9:00 p.m., 70 dB(A); 9:00 p.m.—7:00 a.m., 65 dB(A).
Official source re-checked September 7, 2026: no newer edition of the code had been published (publisher’s edition: Code of Ordinances: Supplement 62 | Land Development Regulations: Supplement 62).
Full Breakdown
A data center sited on industrial land in unincorporated Martin County can't push sound past 70 dB(A) from 7:00 a.m. to 9:00 p.m. or 65 dB(A) overnight, measured at the receiving property line under the county's noise control ordinance. On commercial land the caps drop to 65/60 dB(A), and if the facility abuts residential land, the stricter residential limit (60/55 dB(A)) controls at that boundary. Cooling towers, chillers, and backup generators all count as noise sources under the ordinance.
Violations & Fines
Code inspectors enforce violations under F.S. ch. 162, treating each noncompliant reading as a separate offense; a facility can seek a limited-time or conditioned variance from the Board of Zoning Adjustment.
