Plumbing in Miami
Miami's Exhibit C fee schedule, adopted by Resolution R-26-0200 on April 23, 2026, sets plumbing permits on residential work up to 3 units at 0.50 percent of estimated construction cost. The same exhibit prints $45.00 for residential work estimated under $2,500. Its minimum permit fee is $110.00. State of Florida and Miami-Dade County surcharges aren't in those figures. The permit counter is on the 4th floor of the Miami Riverside Center, 444 SW 2nd Avenue.
Applications go through iBuild, and the city's Building permit page lists 311 or 305-468-5900 for questions. Section 553.79(1)(g) of Florida law exempts single-family owners from a building permit for work valued under $7,500. Plumbing isn't covered. Miami-Dade Water and Sewer's 2025 Water Quality Report, covering January 1 to December 31, 2025, names groundwater from the Biscayne Aquifer as the main source, and the Alexander Orr, Jr. plant uses lime treatment to reduce hardness.
EPA lists Mdwasa Main System (PWSID FL4130871). WASD has submitted a lead service line inventory. It's posted at miamidade.gov/knowyourpipes. The County hasn't used lead as a piping material since 1976, its Know Your Pipes page says, but some properties still list service lines of unknown material, and customers with an unknown line are asked to take a survey. Lead tap sampling data comes from the WASD laboratory, at 786-552-4181 or 786-552-4738, on request.
