Round Rock Office — Q1 2026
Submarket snapshot: occupancy is firming, but small-footprint tenants are doing all the work. Sublease overhang remains the story above 15,000 SF.
The headline number for Round Rock office in Q1 was a 90-basis-point improvement in direct vacancy, to 14.8%. That’s the third consecutive quarter of compression and the tightest the submarket has been since mid-2024. It is also misleading.
What’s actually leasing
Tenants under 5,000 SF accounted for 78% of net absorption this quarter — primarily professional services backfilling spec-suite product along the I-35 corridor. Landlords who have invested in spec suites are leasing them in 30-60 days at face rates flat year-over-year, with concessions trimmed by roughly half a month per year of term.
Above 15,000 SF the story is different. Three blocks of contiguous space came back to the direct market in Q1 — one from a sublease maturity that did not renew, two from right-sizing. Total available space over 15,000 SF actually grew quarter-over-quarter despite the headline compression.
Sublease overhang
The sublease market is what to watch. Sublease availability rose to 240,000 SF, with two-thirds carrying lease term of less than 18 months remaining. Subleases priced 15-25% below comparable direct space are the relevant comp for any tenant with flexibility on timing.
What this means
- Owners with sub-5,000 SF spec product: the market is good to you right now. Hold the line on face rate; expect deals to close in 45-60 days.
- Owners with 15,000+ SF availability: assume the comp is sublease, not direct. Price accordingly or invest in spec demising to participate in the small-footprint demand.
- Tenants under 5,000 SF: the spec-suite window is closing. The best inventory is going first; what’s left in Q3 will be the second tier.
- Tenants over 15,000 SF: there is real leverage here through year-end if you are willing to take sublease term. Direct deals are negotiable but the sublease arbitrage is the lever.
