Key facts for hiring a plumber in Jacksonville
- Jacksonville's permits FAQ: a permit exemption for fixture replacement after the stop excluding water heaters, leak stopping and drain stoppage clearing (read 21 October 2026), quoted below.
- Half of Jacksonville's homes were built in 1987 or earlier (Census ACS 2020-2024).
- USGS well samples of untreated ground water in Duval County (34 wells, 2000-2015, mostly the Floridan aquifer system; not tap water) have a median hardness of 323 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.
- Jacksonville's homes by age: 18.6% (±0.6 points) were built in 1959 or earlier, 20.9% (±0.7 points) from 1960 to 1979, 28.2% (±0.7 points) from 1980 to 1999 and 32.3% (±0.8 points) in 2000 or later (Census ACS 2020-2024, margins of error at 90%).
