A Corner Lot With Two Frontages
Nearly half an acre on a downtown Round Rock corner, zoned MU-L under the district the City Council adopted in October 2025. At 0.436 acres this is close to double the land of 704 up the block, and at $26.31 per square foot it is the cheaper dirt of the two by a clear margin — 22% below 704 on a per-foot basis.
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 19,001 square feet, the buildable footprint runs to 11,401 square feet.
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, this lot is represented as falling outside the Historic Overlay, so demolition is not expected to require a Certificate of Appropriateness — buyer should confirm overlay status with the City before relying on it.

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 less than a year ago.

† 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. 710 E Austin Ave is represented as falling outside the Historic (H) Overlay, meaning no Certificate of Appropriateness is anticipated for demolition or exterior work — buyer should confirm overlay status directly with the City, and note 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.

Downtown Round Rock
Round Rock spent the last decade turning its downtown from a place people drove through into a place they drive to. The city rebuilt the streets, added structured parking, and filled the historic core with restaurants and independent retail. The result is a walkable district with genuine foot traffic — the precondition any small-scale mixed-use project needs.
On October 23, 2025 the City Council rezoned 114 downtown parcels and put 40 of them into the new MU-L district, this lot among them. That is the part worth sitting with: the entitlements on this dirt changed less than a year ago, and the market has not fully repriced what the code now permits. Legally nonconforming buildings may remain, but any expansion has to meet the new standards — which is precisely why the teardown math works here.
The wider fundamentals are the reason Central Texas investors look north in the first place. Round Rock is the Williamson County seat of employment, anchored by Dell's global headquarters, served by Round Rock ISD, and roughly twenty miles up I-35 from downtown Austin — close enough to draw Austin rents, far enough to buy land at a basis Austin no longer offers.
