A 1928 Phoenix Landmark Gets a $135M Hotel Overhaul and What the Project Signals for Southwest Renovation.
Downtown Phoenix just got its most consequential adaptive reuse announcement in years.
Local developer Chris DeRose and his company CivicGroup, alongside Sunflower Development Group, plan to convert the Security Building at the corner of Van Buren Street and Central Avenue into a 255-room hotel through a $135 million renovation. Built in 1928 and currently owned by Maricopa County, the building will be leased to the development team as a hotel for at least 20 years. The renovation scope involves stripping out drywall, carpet, non-historic walls and cubicles while preserving the building’s original historic character. When complete, the property will deliver 15,000 square feet of meeting space including a 5,500-square-foot ballroom and five food-and-beverage concepts — among them a three-meal restaurant and an upscale dining venue.
That’s not a refresh. That’s a total interior rebuild of a near-century-old office tower.
The project landed in news feeds on August 28, right in the middle of a downtown Phoenix hospitality surge. The Denū Hotel & Spa, a $140 million 17-story property at 1 E. Adams Street with 236 rooms and 22,300 square feet of event space, is completing its final work ahead of a September 16 opening. Path Construction wrapped a 54,000-square-foot StudioRes by Marriott extended-stay hotel in Mesa the same week, delivering 124 furnished studio rooms with kitchenettes. The pipeline is not slowing down.
Nationally, hotel construction is the strongest performer among all traditional commercial sectors in 2026. The American Institute of Architects’ July 2026 Consensus Construction Forecast puts hotel spending growth at 4.6% for this year and 5.2% for 2027. Commercial construction broadly is expected to grow 4.8% in 2026, but hospitality is increasingly the category where project economics make the most compelling case.
Renovation Over Ground-Up: The Numbers Back It
The national hospitality picture tells a consistent story. Renovations and additions generated approximately $6.4 billion in hospitality construction revenue in 2025, accounting for nearly 27% of the sector, according to a March 2026 IBISWorld report analyzed by PCL Construction. High financing costs and rapidly evolving guest expectations are accelerating investment in existing assets rather than new development. The Security Building project is a precise expression of that thesis. Maricopa County retains ownership. The development team takes a 20-year lease. You don’t need to buy the land when the public entity is willing to hold it.
For commercial renovation contractors operating in Arizona and the Southwest, adaptive reuse hotel conversions carry a specific set of technical demands that differ from standard hospitality renovation or ground-up work. Historic preservation requirements create a layered scope. Non-historic build-out comes out. Structural and aesthetic elements that contribute to the building’s historic designation stay. That means precision sequencing, detailed coordination between trades, and permit conditions tied to State Historic Preservation Office review rather than a standard municipal building permit process.
Construction material costs nationally climbed 40.3% between January 2021 and April 2026, per IBISWorld data. On a project where the renovation budget is fixed and the historic fabric is irreplaceable, cost overruns are not just a financial problem. They are a project-integrity problem. Getting the scope right up front matters far more than on a vanilla commercial build.
Arizona’s Construction Employment Picture
Statewide construction employment in Arizona stood at 226,700 in July 2026, down 1,800 from June but up 2,100 year-over-year, according to the Arizona Office of Economic Opportunity. The broader statewide labor market saw leisure and hospitality shed 8,300 jobs in July on a not-seasonally-adjusted basis, though much of that reflects typical summer seasonality. Year-over-year, Arizona construction is tracking at 0.9% growth against a national average of 0.7%.
The market is stratifying. Large-scale, complex renovation work requiring specialized skills is accelerating. Commodity-driven ground-up commercial volume is softening under interest rate and material cost pressure. Contractors positioned for sophisticated adaptive reuse and hospitality renovation, particularly in the urban cores of Phoenix and Scottsdale, are operating in a fundamentally different demand environment than those chasing standard build-to-suit.
The Security Building announcement is an early indicator. More historic downtown Phoenix inventory is going to cycle through some version of this conversation over the next five years. The question for renovation-focused general contractors in the Southwest is whether they have the historic preservation experience, the trade sequencing discipline, and the hospitality-specific finish knowledge to compete for these projects when they come to market.
Frequently Asked Questions
What is adaptive reuse in commercial construction?
Adaptive reuse converts an existing building to a new use through significant interior renovation while preserving structural or historic elements. The Security Building project is a hotel conversion of a 1928 office tower. Non-historic interior build-out is removed. Original historic fabric is retained and restored under preservation guidelines.
Why are hotel renovations outpacing ground-up development nationally in 2026?
High financing costs, steep material cost inflation, and accelerating brand refresh cycles are making renovation a more viable path than new construction for most ownership groups. The AIA’s July 2026 Consensus Forecast confirms hotel as the most positive traditional commercial category in the two-year outlook, and PCL’s IBISWorld analysis shows renovation already representing 27% of hospitality construction revenue nationally.
What should Southwest contractors know about historic hotel renovation?
Scope validation against historic preservation requirements is non-negotiable before bidding. State Historic Preservation Office conditions govern what can be removed and what must be retained or restored. Phased interior sequencing, detailed trade coordination, and budget contingencies calibrated to historic material constraints are the baseline, not optional add-ons.
