Austin is not just growing; it is shooting upward. In the span of a few years, the once-modest skyline has turned into a forest of cranes and glass, with new residential towers rising from Lady Bird Lake to Rainey Street. Those high-rises are reshaping how people live, commute, and spend money downtown, and the burst of activity now has Austin competing with, and by some measures edging past, other big Texas metros when it comes to new towers.
Waterline And The New High-Rise Wave
Front and center in this vertical surge is Waterline, a 74-story mixed-use project that has topped out at roughly 1,025 feet and is set to blend luxury apartments, a 1 Hotel, and about 700,000 square feet of office and retail space when it opens in late 2026, according to Community Impact. Coverage from REBusinessOnline and engineering publications noted the tower’s topping-out in August 2025 and cast it as a sign that Austin’s market is now deep enough to support so-called supertall mixed-use buildings. Developers say crews will be busy with interiors and tenant build-outs through 2026 while leasing continues on both the residential and office sides.
CoStar Says Austin Is Pulling Ahead
Data from CoStar Analytics shows Austin out in front of Houston and Dallas-Fort Worth in high-rise development, with much of the momentum coming from multifamily towers instead of traditional, office-only skyscrapers. That tilt toward apartments helps explain why so many new buildings downtown are stacked as mixed-use, with housing over offices and retail on the lower levels, and why the city’s silhouette looks less like a government town and more like a full-blown urban core.
Projects Remaking Downtown
On the street, that trend shows up in specific addresses. Projects such as ATX Tower at 321 W. 6th, the new 415 Colorado tower, and the Residences at 6G are bringing hundreds of units and reviving ground-floor storefronts along key downtown blocks, according to trackers like Aquila Commercial, LoopNet, and notes from MMG Real Estate Advisors. The formula of apartments above office floors and shops is showing up again and again in the Warehouse District and Rainey Street area, part of a calculated effort by developers to serve downtown workers as well as renters who want a walkable neighborhood with restaurants, bars, and services within a short stroll.
Rules Of The Road
City officials are trying to keep up with the boom and set clearer limits on how tall the next wave can be. An interim zoning change put a 350-foot by-right height cap on most of the central business district and kept the Downtown Density Bonus Program in place as the route to build taller in exchange for community benefits, a framework detailed by ENR. The move was prompted in part by state legislation that narrowed some local zoning powers and is meant to serve as a temporary fix while the city works on a full rewrite of downtown regulations.
