Rancho Sienna is a master-planned community along Ronald Reagan Boulevard at the crossroads of Georgetown and Liberty Hill. Despite a Georgetown mailing address, the community falls within Liberty Hill ISD. Six builders offer homes from the mid-$300s to $600s with Hill Country views, 100+ acres of parks, and a resort-style pool.
Georgetown’s Rancho Sienna corridor
Rancho Sienna stands out as one of Georgetown’s few master-planned communities built around environmental responsibility from the ground up. Spread across 600 acres at the corner of Ronald Reagan Boulevard and Highway 29, the neighborhood opened in 2012 and has matured into one of northwest Georgetown’s most established options for families and relocating buyers.
The community sits roughly 25 miles northwest of Austin, close enough for commuters but far enough to avoid the congestion that defines communities closer to I-35. Builders here have emphasized energy-efficient construction and native landscaping, which keeps utility costs lower than many comparable Georgetown subdivisions.
Rancho Sienna Elementary anchors the neighborhood’s school options within Georgetown ISD. For buyers comparing locations across the metro, the Austin neighborhood directory provides a side-by-side look at how Georgetown communities stack up against other submarkets.

Where to focus inside Rancho Sienna
Rancho Sienna is a single master-planned community rather than a collection of distinct sub-neighborhoods with separate names. The development is organized into phases and sections that rolled out over time starting in 2012, with earlier phases clustered closer to the amenity center off Ronald Reagan Boulevard and newer sections pushing south and west across the 600-acre footprint. Builders like Taylor Morrison, Ashton Woods, and Gehan Homes each built in designated sections, so you can often identify which part of the community you’re in by the builder style and lot size.
The practical difference between sections comes down to lot width, tree coverage, and proximity to the community pool and Sienna House amenity center. Homes closer to the original entry off Highway 29 tend to sit on more established landscaping with mature trees, while lots on the western edge back up to open space and offer wider rear views. There are no gated sub-sections or separate HOA structures within the community.

HOA dues run $100 to $200 per month depending on your lot and section.

Getting around from Rancho Sienna
Ronald Reagan Boulevard south to Highway 183A is the fastest route to Cedar Park and northwest Austin, running about 25 minutes outside of rush hour. During morning peak traffic from 7:00 to 8:30, that stretch can push past 40 minutes as 183A merges into MoPac congestion. Heading east on Highway 29, downtown Georgetown is only 10 to 12 minutes, making it one of the easier commutes in the area.
Buyers working at Fort Cavazos should plan on 50 to 60 minutes via I-35 north, though the toll roads through Temple can shave off time on lighter days. For those comparing options farther west, the Best Neighborhoods in Liberty Hill sit along similar commute corridors but add a few minutes to Austin-bound routes. Remote and hybrid workers get the best deal here, with Georgetown’s local retail and dining close enough that most errands stay under 10 minutes.
