Summary

Miami-Dade County caps sound from rural event venues, farm wineries, breweries and distilleries, and other agritourism uses in the AU Agricultural District at 70 dBA or 80 dBC, measured from 200 feet off the property line or from any point on an adjoining residential lot. The limit applies on top of the countywide noise ordinance and is enforced with calibrated sound meters.

City-specific rules exist: Miami, and Coral Gables have their own decibel limits rules that differ from Miami-Dade County's county-level regulations. If you live in one of those cities, check the city-specific page instead.

Sound emanating from the property with the agritourism use shall not exceed 70 dBA or 80 dBC, when measured: i.from any point at least 200 feet from any exterior property line of the property with the agritourism use; or ii.from the property line of any abutting or adjacent property with a residential use, or from any other point on such abutting or adjacent property.2.Measurement shall be performed by a sound level meter that has been calibrated using a sound level meter calibrator at the measurement site prior to measurement.3.A violation of this requirement shall be presumed to occur if sound exceeds the foregoing limitations for a continuous duration of one minute within any 5-minute period. Each minute of violation and each side of the property from which a violation is measured shall constitute a separate offense.

Full Breakdown

1. The cap applies to rural event venues permitted under subsection (8), farm-related wineries, breweries and distilleries permitted under subsection (26), and ancillary agritourism uses such as farm tours, U-Pick operations and small-scale outdoor amusements permitted under subsection (27)(c)2 and 3. Sound leaving the property cannot exceed 70 dBA or 80 dBC, the C-weighted scale, which is more sensitive to bass and other low-frequency sound. The county measures compliance from two vantage points: at least 200 feet from the property's own boundary, or anywhere on an abutting or adjacent residential lot, whichever the inspector chooses.

Inspectors use a calibrated sound level meter that meets ANSI or IEC Type 1 or Type 2 standards, checked against a field calibrator at the measurement site before each reading. A violation is presumed once sound exceeds the limit for a continuous minute within any five-minute window, and the code treats every minute of exceedance, and every side of the property where it is measured, as a separate offense. 07, Florida Statutes.

Violations & Fines

A property with three or more noise violations on different days within 12 months loses eligibility for a new or renewed Certificate of Use for the agritourism activity, and the Director can revoke an existing one, unless all outstanding violations and liens are cleared and a $25,000 bond is posted with the Department. Interfering with an inspector investigating a noise complaint or enforcing the limit is itself a separate violation of this section.

Frequently Asked Questions

Does the 70 dBA limit apply to my backyard party?
No. Section 33-279(27)(d) only governs agritourism uses in the AU Agricultural District: rural event venues, farm wineries, breweries, distilleries and similar farm-ancillary activities. Ordinary residential noise is instead governed by the countywide nuisance-noise rule in Section 21-28, which uses a 100-foot audibility test rather than a decibel meter.
Where does the county measure the sound from?
Either at least 200 feet from the agritourism property's own boundary, or from any point on an abutting or adjacent residential property, whichever location the inspector chooses. Both are measured with a sound level meter checked against a field calibrator immediately before the reading is taken.
What happens after repeated violations?
Three or more noise violations on different days within a 12-month period bar the Director from issuing or renewing the venue's Certificate of Use, and an existing CU can be revoked, unless the owner clears all outstanding violations and posts a $25,000 bond with the Department.
Is there a quiet curfew on top of the decibel cap?
Yes. These same agritourism uses may only run between 9:00 a.m. and 11:00 p.m., and no outdoor amplified sound is allowed at all between 11:00 p.m. and 9:00 a.m., regardless of decibel level.
