78664 covers a well-established stretch of Round Rock, the kind of area where you’ll find homes built anywhere from the early 1990s through the 2010s sitting a few streets apart. I’m Robbie English, REALTOR, Broker with Uncommon Realty, and here’s what actually matters if you’re looking here.
This zip code mixes established neighborhoods like Chandler Creek and Round Rock West with newer infill construction, which gives buyers a range of price points and lot sizes you won’t find in Round Rock’s newer, further-out sections. Round Rock is home to major employers including Dell Technologies’ headquarters, which sits inside 78664 and has shaped commute patterns and housing demand across the city for decades. The Round Rock Premium Outlets and Kalahari Resorts Round Rock are also nearby, adding retail and hospitality jobs and a steady stream of visitor traffic to the local economy.
What to Actually Check
Confirm the specific Round Rock ISD campus assignment, since attendance zones can vary street by street even within the same neighborhood. Ask about the age of major systems (roof, HVAC, water heater) on any home over 15 years old, and check whether an HOA applies, since older Round Rock neighborhoods vary in whether they have one — some, like Chandler Creek, come with a pool and tennis courts, while others have no shared amenities at all.
Comparing 78664 to Nearby Round Rock Zip Codes
If you want more of a master-planned feel with a golf course and resort-style pools, I’d also point you toward 78665 on the northeastern side of the city. 78664’s advantage is usually the lot age, established trees, and proximity to Dell and the outlets, not amenity packages.
Portions of 78664 also extend into Pflugerville, so don’t assume every address in this ZIP code pays Round Rock property tax rates or falls under the same municipal services — that’s another item worth confirming before you write an offer, not after.
