Sun City Georgetown Isn't One Community — It's Thirty Years of Them

Del Webb broke ground on Sun City Georgetown in 1996. Nearly three decades later, the same gate, the same HOA, and the same community name cover homes built across four distinct eras — new construction still selling from $231,000 alongside resale homes from the original phases reaching $900,000-plus. Which section of the 5,300 acres you buy into matters as much as the community you picked.

Approved for 10,550 homes total — roughly 7,500+ occupied today

That gap between "occupied" and "approved" is the detail worth sitting with: Sun City Georgetown is still roughly 3,000 homes from full build-out. A buyer moving into a newer section today isn't moving into a finished, settled community the way the 7,500-homes number might suggest — they're moving into a development that will likely still be under active construction, with the traffic, dust, and equipment that comes with it, for years to come.

What the price spread actually reflects

A $231,000 new-construction listing and a $900,000-plus resale are not really competing for the same buyer, even though both carry the "Sun City Georgetown" name. The cheaper end reflects current entry-level new-construction floor plans; the top end reflects premium lots, larger square footage, or original-phase homes with mature landscaping in the most established sections. Comparing the two by price alone tells you almost nothing about lot location, construction era, or proximity to whatever's still being built.

None of this makes newer sections a worse choice — for a buyer who wants current finishes and floor plans, and doesn't mind nearby construction activity for a few more years, it's a reasonable trade. It just means "which phase" is a real question to ask before touring, the same way you'd ask "which county" in a multi-county market — except here the variable sits inside a single HOA rather than across a map.

The one number that applies the same way regardless of which phase you buy intoGeorgetown ISD's school tax rate — the largest single line on the bill — freezes permanently once you file the over-65 exemption with Williamson County Appraisal District, regardless of which era of Sun City Georgetown you buy into. File within 30 days of closing; the freeze locks that year's amount for as long as you own the home, whether it's a 1998 original-phase house or a home closing this year.
If the scale and ongoing construction aren't for youThe Colony at Williamsburg and Sage Cobblestone are smaller, already-established or newer alternatives in the same Georgetown/Round Rock corridor, without Sun City's scale or its multi-decade build-out timeline. Overture Georgetown, a 55+ rental-only community, is worth a look purely as a rent-vs-own comparison point before committing to a purchase in any phase.

The honest first question at Sun City Georgetown isn't "is this the right community" — at 7,500-plus homes and counting, it almost certainly has a section that fits your budget. It's "which phase, how close to the remaining 3,000 homes of construction, and what era of finishes" — because within this one gate, those answers vary about as much as they would across four separate communities anywhere else in this guide.
