Tour boats blasting narration through megaphones along county waterways would be silenced under a new Miami-Dade County ordinance headed to the commission.
District 5 Commissioner Vicki Lopez introduced legislation that would prohibit amplified speakers, megaphones and any other outward-facing sound devices on paid tour boats operating in county waters. Tour operators could still use microphones, but only to broadcast audio into personal headsets worn by passengers.
The ordinance is scheduled for first reading as Agenda Item 4(C) at the Board of County Commissioners meeting on Tuesday, Sept. 1.
Why it matters locally
The ban would apply countywide, including within incorporated cities like Aventura and Sunny Isles Beach, unless a municipality has adopted its own noise regulations and formally notified the county clerk that it does not want county enforcement.
The ordinance's preamble states that increased tourism has led to more vessel-based tours, and that amplified sound from those tours causes negative impacts for residents and visitors on the water and on shore.
It also notes that noise crosses jurisdictional boundaries and that enforcement officers face challenges tracking municipal lines on Biscayne Bay and other waterways.
What the ordinance does
The legislation amends Section 21-28 of the Miami-Dade County Code, which governs noise regulations. Beyond the megaphone ban, it expands and clarifies the county's authority to enforce noise rules inside municipalities.
The preamble frames the measure as a quality-of-life issue, stating that tourism should not create undue harm for residents even as it remains crucial to the county economy. Lopez, a former state representative appointed to the District 5 seat in November 2025, requested the ordinance through the County Attorney's office.
Miami Herald reporter Doug Hanks, who covers Miami-Dade County government, flagged the legislation on X on Wednesday, Aug. 26:
@doug_hanks: "No more megaphones for tour boats in Miami-Dade County under legislation by @commvickillopez -- people on the tour would have to wear headphones to hear the guide. Have waterfront homeowners been complaining?"
What's next
Six weeks must pass between first reading and a public hearing, meaning the earliest a final vote could occur is mid-October. Municipal officials must receive four weeks' notice before the public hearing. If enacted, the ordinance takes effect ten days after passage unless vetoed by the county mayor.
No co-sponsors have been publicly identified. Reactions from tour boat operators were not available as of publication.
Residents can attend the Sept. 1 commission meeting or submit comments through the county's legislative portal.
