Yes. Miami Beach is a regular stop on the route, not an edge case.
Miami Beach was incorporated in 1915, and most of the housing stock standing today went up across the 1920s through the 1960s. Work inside the Art Deco and MiMo historic districts goes through an additional preservation review on top of the ordinary building permit, which affects timeline more than the plumbing itself.
Miami Beach is fully served by county or city water and sewer, with no meaningful well-and-septic presence left to plan around, and on top of that, king-tide flooding is documented enough here that the city itself funds pump-station work to manage it, which is one more thing a technician checks before recommending outdoor or ground-level work.
Before a job like this starts, the City of Miami Beach building department has to sign off, and filing that paperwork sits on us, not on you.
