Key facts for hiring a plumber in Miami
- Miami's permit page: a permit rule for water heater replacement (read 17 October 2026), quoted below.
- Half of Miami's homes were built in 1979 or earlier (Census ACS 2020-2024).
- USGS well samples of untreated ground water in Miami-Dade County (84 wells, 2009-2023, mostly the Biscayne aquifer; not tap water) have a median hardness of 237 mg/L as calcium carbonate, which USGS classes as very hard. That is a well reading, not a tap-water reading: a utility may draw from other sources or soften its water before it reaches you, so ask your water utility what your tap water measures before you pay for a softener.
- Miami's homes by age: 29.8% (±0.9 points) were built in 1959 or earlier, 21% (±0.9 points) from 1960 to 1979, 12.8% (±0.7 points) from 1980 to 1999 and 36.4% (±1.0 points) in 2000 or later (Census ACS 2020-2024, margins of error at 90%).
