Full Breakdown
Coral Gables exempts routine testing and operation of emergency backup energy generators from its general noise ordinance only if run between 11:00 a.m. and 2:00 p.m., Monday through Friday, and only if the sound stays at or below 80 dBA measured from the nearest property line. Generators on single-family lots, or on properties abutting a single-family lot, face a tighter 70 dBA cap. Units permitted and closed out before November 9, 2021 are grandfathered out of the dBA caps but must still keep to the testing-hour window. Portable generators run during a declared weather-related state of emergency are exempt from the dBA limits entirely.
Violations & Fines
Testing outside the 11 a.m.-2 p.m. Monday-Friday window, or exceeding 80 dBA (70 dBA for single-family properties) at the property line, forfeits the noise-ordinance exemption and exposes the operator to enforcement by police or code enforcement under the general noise article.
