The Value Is In The Location
Just under a fifth of an acre of downtown Round Rock carrying the MU-L mixed-use zoning the City Council adopted in October 2025. The two-bedroom house standing on it needs major repairs, and the price reflects that — this is not a renovation play dressed up as a deal. What you are buying is 8,640 square feet of land inside a district whose development rules were rewritten in October 2025.
At $300,000 the land basis works out to $34.72 per square foot. The MU-L code permits up to three detached principal buildings on a single lot, none larger than 2,800 square feet, within a 60% lot coverage cap — which on this parcel means as much as 5,184 square feet of building footprint. Height runs to two and a half stories. That is a materially different use than the single small house sitting there today.
The rear yard is deep and canopied by mature shade trees, with a stone outbuilding near the back line. The lot sits outside the Historic (H) Overlay on the City’s downtown zoning map, so demolition does not require a Certificate of Appropriateness — one of the more expensive and unpredictable steps a downtown teardown can face.

What You Can Build
On October 23, 2025 the Round Rock City Council overhauled downtown zoning and rezoned 114 parcels — 40 of them into the new MU-L (Mixed-Use Limited) district. 704 E Austin Ave carries that zoning. MU-L is built to keep the residential scale and historic character of the east end of downtown while opening the door to small-scale commercial and multi-building residential. That is the whole thesis on this lot: the structure is past saving, but the entitlements underneath it changed in October 2025.

† Permitted with Supplementary Use Standards — allowed in MU-L, but subject to additional conditions in Sections 2-77 and 2-91 of the Zoning and Development Code. Confirm the standards for your intended use before you rely on it.
MU-L permits restaurants, event centers, enrichment centers and upper-story residential only on lots fronting Main Street or Georgetown Street. This parcel fronts E Austin Ave, so those four uses are off the table here — as are mobile food establishments, which carry the same frontage restriction. Plan around the list above, not the full MU-L use table.
Buyer and buyer's agent are solely responsible for independently verifying every figure, permission, and development assumption on this page before submitting an offer. That includes zoning and district designation, permitted and conditional uses, supplementary use standards, setbacks, height, lot coverage and buildable area, parking, driveway and access rights, platting or replatting requirements, demolition permitting, utility availability and capacity, easements, floodplain, impact and development fees, and any overlay, deed restriction, or covenant affecting the property. Nothing here is a representation or warranty by Migma LLC, Ron Natal, or Hart of Texas Realty as to what may actually be built, permitted, or approved.
Standards are summarized from the City of Round Rock Downtown Mixed-Use Zoning User Guide (v1.1, released February 5, 2026), which is itself a plain-language summary. The controlling documents are the City's Zoning and Development Code — including Sections 2-73, 2-77 and 2-91 — and the adopting ordinances from the October 23, 2025 downtown rezoning. Where this page and the Code differ, the Code governs.
Lot-specific figures, including buildable footprint, land basis, and square footage, are calculated from the reported lot size and have not been confirmed by survey. Acreage, lot lines, and legal description should be verified by a current survey and title commitment. 704 E Austin Ave sits outside the Historic (H) Overlay on the City's downtown zoning map, so no Certificate of Appropriateness is required for demolition or exterior work — note, however, that all MU-L buildings must still comply with the City's Historic Design Guidelines for Residential Properties regardless of overlay status.
Direct all zoning, permitting, and buildability questions to City of Round Rock Planning and Development Services prior to offer. Buyer is encouraged to engage a licensed architect, engineer, surveyor, and land-use counsel to confirm feasibility.

The Documents
The 1952 Starkfield Addition restrictions imposed a 30-foot front building line, a 700 sq ft minimum floor area, and a ban on commercial use — and they terminated by their own terms on March 18, 1977. Nothing replaced them. The 1953 and 1954 instruments only release and ratify the release of a racial covenant, void under federal law regardless. Nothing in the chain limits the number of dwellings per lot. The recorded documents are below so you can read that for yourself rather than take it from a listing page.
Provided for buyer convenience only. Recorded instruments are reproduced as filed in the Williamson County real property records. Buyer and buyer's agent should obtain their own survey, title commitment and legal review, and should not rely on these copies as a substitute for either.
