Why Berkeley County Matters for 55+ Buyers
Most buyers researching "Summerville 55+ communities" assume they are comparing apples to apples on property taxes. They are not. Del Webb Cane Bay, Four Seasons at Lakes of Cane Bay, and Hammock Walk at Nexton are in Berkeley County. Del Webb Nexton, Horizons, Cresswind, and most other Summerville communities are in Dorchester County. The difference is approximately 0.16 percentage points in effective tax rate — small-sounding but meaningful in cumulative cost.
Berkeley County Tax Rate
Berkeley County's effective property tax rate for legal residences runs approximately 0.51% — versus Dorchester County's ~0.67%. This rate reflects Berkeley's combined millage structure after Act 388's school operating tax elimination for legal residences. Berkeley County has historically maintained lower millage rates than Dorchester, in part due to the industrial and commercial tax base from the Volvo plant, Boeing facilities, and other major employers that fund county operations without placing the burden on residential property owners.
