Frequently Asked Questions

What is the current office vacancy rate in Austin?
About 15.7% as of Q1 2026 — elevated by historical standards, but declining year-over-year for the first time since 2022 as demand returns.
What are Austin office rental rates in 2026?
Full-service asking rents average about $42 per square foot. By class: Class A around $51, Class B around $37, Class C around $33. For Class A on a triple-net basis, suburban submarkets run $24 to $33 NNN, the CBD and Domain run $38 to $46, and trophy space is near $53.
What is the difference between full-service and triple-net (NNN) rent?
Full-service (gross) rent bundles operating expenses, taxes, and insurance into one rate. Triple-net quotes a lower base rate plus your share of those expenses on top. Comparing offers apples-to-apples matters, because the cheaper NNN rate often is not.
How much office space does my business need?
A practical starting point is 150 to 250 square feet per employee (about 3 to 5 people per 1,000 SF), depending on how many private offices and conference rooms you need versus open space.
Which Austin submarkets should I consider?
It depends on budget and talent. The CBD and Domain/North carry premium Class A pricing, while the Northwest and Southwest offer comparable quality at meaningfully lower rates. The spread between downtown and the suburbs is as wide as it has been in years.
Do I need a tenant rep broker, and what does it cost?
In Austin, tenant and buyer representation is paid by the landlord at closing through a commission already built into the deal. Having your own broker costs you nothing extra and gives you real market leverage.
How long does it take to lease office space in Austin?
Plan on three to six months for most deals: a few weeks to tour and shortlist, then 30 to 60-plus days to negotiate the lease and complete any build-out.
Is now a good time to lease or renew office space in Austin?
For tenants, yes. Vacancy above 15% means landlords are competing for good credit, and concessions like free rent and tenant-improvement allowances are on the table. That window narrows as absorption rises, so timing matters.
How should Austin property owners approach leasing up space right now?
Price to current data, market aggressively with premium listing exposure and direct outreach, and stay flexible on term. Well-positioned, well-marketed space is leasing; overpriced or quietly-listed space is sitting.
