The Pérez Art Museum Miami wants a $2.5 million boost in government support, with taxpayers set to cover a third of the museum’s budget next year.

Housed in a new $130 million waterfront headquarters built largely with government money, PAMM’s celebrated debut late last year also tripled the non-profit’s annual operating expenses, to $14 million from $5 million. Private dollars have not kept pace with the higher costs, leaving a gap that PAMM wants Miami-Dade to help close with a 60 percent increase in the museum’s operating subsidy from hotel taxes, according to interviews and budget documents.
