A Corner Lot With Two Frontages
A downtown Round Rock corner zoned MU-L under the district the City Council adopted in October 2025. Survey puts it at 0.290 acres — 12,634 square feet — roughly 46% more land than 704 up the block. It is also the cheaper dirt: $27.70 per square foot here against $34.72 at 704. More land, a lower basis, and the corner.
The corner is the point. Two street frontages give a site plan options a mid-block lot simply does not have: separate vehicular access, more flexible placement for the three detached buildings MU-L permits, and street presence on two sides for any commercial use. With a 60% coverage cap on 12,634 square feet, the buildable footprint runs to 7,580 square feet — roughly 2,400 square feet more than 704 allows.
The house itself is a two-bedroom, one-bath with original wood trim, a stone fireplace, and an enclosed sun porch — dated throughout, with an original kitchen and a single bath, but more intact than its counterpart up the block. A detached two-bay garage sits at the rear off the gravel drive. As with 704, the lot sits outside the Historic Overlay on the City’s downtown zoning map, so demolition does not require a Certificate of Appropriateness.

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. 710 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. ‡ Permitted in MU-L only on lots fronting Main Street or Georgetown Street — in play here on the strength of this lot’s Georgetown frontage, not of the district, and subject to the City’s development approval.
MU-L permits restaurants, event centers, enrichment centers, upper-storey residential and mobile food establishments only on lots fronting Main Street or Georgetown Street. This is a corner: it can be oriented to either E Austin Ave or N Georgetown St, and taking the Georgetown frontage puts those five uses in play — they are marked ‡ above. A mid-block MU-L lot cannot reach them at all. The orientation goes through development approval with the City, so confirm it with Round Rock Planning and Development Services before you underwrite to any of the five.
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. 710 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
Two separate sets of private restrictions once governed this lot, and both have lapsed. The 1947 deed that conveyed Lots 13 and 14 imposed a 30-foot front building line, a 750 sq ft floor minimum and a ban on commercial use — terminated by its own terms on January 1, 1968. The 1952 subdivision restrictions imposed much the same and terminated March 18, 1977. The 1953 and 1954 filings only release and ratify the release of a racial covenant, void under federal law regardless. Nothing in the chain limits dwellings per lot. Note that the recorded utility easements are a different matter — those survive, and this parcel carries several. Read them yourself below.
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.
