Every original Tega Cay foundation predates the town itself
Tega Cay was built in 1970 as a gated Lake Wylie community on former India Hook Hills land Duke Power sold to Charlotte's Ervin Company, and residents didn't vote to incorporate as a municipality until July 4, 1982, so every foundation poured in the original development is at least twelve years older than the town government now regulating it.
Peninsula clay and fifty years of settlement
The peninsula's original name, India Hook Hills, described the red-clay spur jutting into the Catawba River, the same shrink-swell clay that's now had over five decades to work on Tega Cay's original 1970s foundations, longer than on houses built in the community's later development phases.

What to tell us about your Tega Cay foundation
Tell us whether the property dates to the original 1970s development or a later phase, and where cracking or settlement is visible. That timing detail matters more in Tega Cay than in a town built in a single era.
Fifty years of peninsula settlement and support planning
Original 1970s Tega Cay construction has had roughly fifty years to settle into the peninsula's red clay, more than enough time for pier and support needs to differ from a house built in a later development phase on the same street.
