Do you need a permit for water softener installation in Allentown, PA?
Usually yes
In most cases yes — Lehigh County and the City of Allentown generally require a permit for water softener installation. Height, size and location on the lot determine the exact review, so confirm with the building department before you start.
Allentown sits in Lehigh County, Pennsylvania. Deep frost lines, snow load and a very old housing stock mean permits frequently touch structural, electrical and energy-code upgrades at once. Work outside city limits is permitted by the county building department rather than the city.

Frequently asked questions
Is Florida water hard?
Most of Florida draws from limestone aquifers, so hardness of 10 to 20 grains per gallon is typical. That is hard to very hard, and it is the main reason Florida water heaters scale up faster than the national average.
