The First Industrial Phase at Halo Vista, Next to TSMC's Phoenix Campus
Mack Real Estate Group and McCourt Partners have detailed the first industrial phase of Halo Vista, a 2,300-acre mixed-use district in North Phoenix anchored around Taiwan Semiconductor Manufacturing Co.'s expanding chip campus. The initial industrial component comprises seven buildings totaling more than 780,000 square feet at West Dove Valley Road and North 43rd Avenue, immediately adjacent to TSMC's site.
The developers said the buildings will have flexible layouts intended for TSMC suppliers, service providers and other advanced manufacturers that want to be close to the chipmaker's workforce and infrastructure. The announcement follows TSMC's decision to raise its U.S. semiconductor investment to $265 billion, reinforcing the corridor's role as a strategic manufacturing location.
Halo Vista's broader plan calls for roughly 30 million square feet of mixed-use development, including manufacturing, research and education districts, offices and nearly 9,000 homes, with completion expected to take 15 to 20 years. The project held a ceremonial groundbreaking in March for its hospitality and retail phase, and construction of the Costco portion is expected in the fourth quarter.
The industrial piece is part of a larger 2.5 million-square-foot industrial target. TSMC's Phoenix campus, meanwhile, is planned for six fabrication plants, two advanced packaging facilities and an R&D center. Its first fab is producing chips, and a second fab is targeted for 2027.
Why Mack and McCourt Are Moving Now on TSMC Supplier Space
Proximity is the product
The announcement is explicitly aimed at TSMC suppliers and service providers. By placing flexible industrial buildings directly beside the chip campus, Mack and McCourt are betting that logistics cost, response time and access to TSMC's manufacturing ecosystem will outweigh whatever rent premium the location may command. This is a demand-led strategy: rather than announcing a speculative tenant or particular use, they are marketing proximity to one of the world's most important chipmakers.
Why the developers are activating sites now
Chris Janson, president of Mack Halo Vista, said the goal is to stay ahead of TSMC supplier demand. That timing matters. The second Phoenix fab is scheduled for 2027, and upstream suppliers often secure space well before plant start-up. By opening vertical development now, the developers aim to show that their industrial land is development-ready before suppliers commit to competing sites elsewhere in the corridor.
The Phoenix land race around TSMC
Since TSMC announced its Phoenix project in 2020, industrial developers have competed aggressively for sites near the campus. Halo Vista's 2.5 million-square-foot industrial ambition makes it one of the larger supplier-oriented plays in the area, but it is not the only one. The announced first phase should be read as an opening move in that competition, not proof that tenant demand has already materialized.
Signed tenants and delivery dates remain open questions
The release does not identify any signed occupiers, rental rates, delivery dates or building specifications beyond flexible layouts. Those details will determine whether the project translates TSMC's ecosystem growth into committed industrial absorption, or whether North Phoenix ends up with a wave of speculative supply waiting for the same supplier pool.
What the Halo Vista Industrial Launch Means for Tenants and Landowners
For businesses, developers and investors watching the TSMC supplier corridor, the Halo Vista announcement creates specific signals rather than a generic industrial story.
- Suppliers considering the corridor should request confirmed building specifications and delivery timing from Mack and McCourt now. The release confirms flexible layouts and an explicit aim to stay ahead of supplier demand, but it does not disclose delivery dates or signed occupiers.
- Competing industrial landlords should treat the 780,000-square-foot first phase as live competition for TSMC-linked occupiers. The developers explicitly say the land is being activated to beat supplier demand to market.
- Investors and brokers should watch for pre-leasing announcements before TSMC's second fab target in 2027. The development's credibility will hinge on whether actual suppliers commit to space, not just on the $265 billion TSMC investment headline.
- Phoenix-area trade partners and service providers can use the Q4 Costco construction start and the 30 million-square-foot, 15-to-20-year buildout as concrete timing markers for future procurement and contracting opportunities.
Risk & Opportunity Assessment
| Commercial Risk | Medium | The first 780,000-square-foot industrial phase is speculative: no signed occupiers are named in the release, so lease-up depends on TSMC supplier localization and timing. |
| Competitive Risk | High | Industrial developers have been racing to secure TSMC-adjacent sites since 2020, and Halo Vista's 2.5 million-square-foot industrial target will compete for the same supplier demand. |
| Regulatory Risk | Low | The developers worked closely with the city of Phoenix for years, and the project has already held a ceremonial groundbreaking and begun initial phases, suggesting core entitlements are in place. |
| Reputation Risk | Medium | Halo Vista is promoted as a city within a city and a future semiconductor powerhouse, but its 15-to-20-year delivery timeline and the absence of signed industrial tenants could pressure credibility if pre-leasing lags. |
| Technology Disruption | Low | The project supports established semiconductor manufacturing rather than a competing technology; the main exposure is the pace of TSMC supplier localization, not obsolescence. |
| Commercial Opportunity | High | TSMC's $265 billion U.S. investment and the planned expansion to six fabs, including a second Phoenix fab targeted for 2027, create a tangible demand pool for nearby supplier-focused industrial space. |
