Miami Requires 60% Support for Charter Changes, Stricter Than Tampa and Orlando

Miami-Dade County requires a 60 percent supermajority for most citizen-initiated charter amendments placed on the ballot, a rule that applies to proposals affecting property taxes, zoning and public facilities. This standard governs how measures reach the November 2026 ballot and determines whether they take effect after certification by the county canvassing board.

The requirement stems from the county charter last amended in 2012 and stands in contrast to simple-majority rules used for similar local questions in Tampa and Orlando. County election officials prepare the ballot language at least 90 days before the election under Florida statutes that set signature thresholds for petitions at 10 percent of registered voters in the most recent gubernatorial race.

Effects on Local Services and Costs

Residents in neighborhoods such as Little Havana and Overtown would see direct consequences if a measure to expand Metrobus routes or add stormwater pumps reached the ballot. A proposal that secures 55 percent support would fail under the current threshold, leaving existing county budget allocations unchanged for those programs. The fiscal year 2025 county budget document lists $312 million for transportation and $87 million for parks and recreation, figures that would remain in place absent a successful referendum.

Local advocates note that the higher bar limits the number of measures that qualify for the ballot each cycle. In the 2024 election, three of five citizen petitions fell short of the required signatures before the deadline set by the elections department.

Comparison to Other Florida Jurisdictions and Next Steps

Policy analysts point out that Jacksonville and St. Petersburg allow many local tax and bond questions to pass with a simple majority when placed on the ballot by the city council. Miami-Dade's process therefore places a greater emphasis on broad consensus before new revenue measures can take effect. The county elections department is scheduled to release its voter information pamphlet by early October 2026, which will list all certified measures along with the exact wording and the applicable approval percentage.

Ballots will be mailed to eligible voters starting 40 days before election day. County staff will verify results within 10 days after polls close, after which any approved measures are incorporated into the charter and take effect on the date specified in the measure itself.
