Arizona Went to Taiwan to Talk Chips. Housing Kept Coming Up.

In the first week of September, Neighborhood Ventures co-founder John Kobierowski joined roughly 30 Arizona business and political leaders on the Arizona Commerce Authority's delegation to Taipei for SEMICON Taiwan, the agency's third trip to the island this year, according to In Business Phoenix. John was selected to represent the state's multifamily sector. A chip trade mission does not normally need an apartment operator. This one did because, as John put it after a week of meetings, "housing is being treated as core infrastructure, not an afterthought."

The Commitment Behind the Trip Keeps Growing

On July 16, TSMC announced another $100 billion for Arizona, four more fabs at 2 nanometers or below, bringing its total commitment in the state to $265 billion, per the Arizona Commerce Authority. The full program now covers 10 fabs, two advanced packaging plants and a research center, which officials describe as the largest foreign direct investment in U.S. history. The first fab has run volume production since late 2024, the second is built and slated to start in 2027, and a third broke ground this year, per the Taipei Times.

The Supplier Wave Could Outgrow the Fabs

The number that stuck with John was not TSMC's. "Taiwanese officials and semiconductor executives both described dozens of ancillary suppliers and support firms that are likely to follow TSMC to Arizona," he said. In conversations, the figure floated was more than 300 suppliers and vendors covering advanced plastics, packaging materials, chemicals and maintenance products. That is talk, not a filing, and no public count exists yet, but the direction matches the record. Since 2020 Arizona has attracted more than 70 semiconductor expansions totaling over $314 billion, per the Commerce Authority, and TSMC has said it wants its upstream chemical and equipment suppliers to follow it to the United States. Trade between Arizona and Taiwan grew from $3 billion to more than $21 billion in three years, Commerce Authority president Sandra Watson told KJZZ.

Housing Is a Prerequisite, Not the First Wave

"In meetings with Taiwanese business leaders, workforce housing came up repeatedly as a prerequisite for any economic development deals," John said. He was equally clear about sequencing. "Housing is not the first wave of CRE needs. Getting the plant online, ancillary industrial and manufacturing space, some Taiwanese-based retail and office lead the wave today." The ground next to the fabs bears that out. Halo Vista, a 2,300-acre, $7 billion master plan from Mack Real Estate Group and McCourt Partners, broke ground on March 26 with industrial as its largest component, per the Greater Phoenix Economic Council.

The Demand Will Split in Two

John expects "a bifurcated demand curve." Engineers and relocating executives will want move-in-ready, higher-end rentals near the corridor. Construction and manufacturing workers will need workforce-tier housing around town. Two details cut against easy assumptions. Taiwanese employees who relocate permanently "will most likely be drawn towards homes and home ownership," he was told, so the rental demand from that group is a stage, not a destination. And many TSMC-linked workers arrive in phases, for site visits, short assignments and training rotations before a permanent move, which "favors multifamily operators who can offer furnished or flexible-term units alongside traditional leases." John points to Hsinchu Science Park, where TSMC's suppliers cluster in Taiwan, as the preview. In his telling, rents and land values near that corridor rose quickly once the fabs matured, which argues for looking at the submarkets around north Phoenix now rather than waiting for the peak.

The Numbers Today Are Smaller Than the Headlines

TSMC Arizona employs more than 3,500 people, per the Commerce Authority, a meaningful employer in a metro of roughly five million but not yet a transformational one. The Taipei Times report listed water, power, visas for overseas hires and labor shortages as live concerns. The demand arrives in phases, and most of it is still ahead.

The Bigger Picture

The delegation came home describing a relationship "built for the long haul, not just a one-off investment cycle," with more delegations, academic exchanges and business partnerships planned. Taiwanese family investment firms told John their interest in Arizona real estate is growing because of TSMC's commitment. Luxury product next to the fabs will serve the top of the pay scale. Most of the headcount will look farther out, at older communities with rents a working household can carry.

For Neighborhood Ventures, John's week in Taipei confirmed what we underwrite toward. New supply near TSMC is being built at a basis that requires top-of-market rents, while the suppliers following it will bring a workforce that needs renovated 1970s and 80s communities within a reasonable commute, on lease terms flexible enough for people who arrive in stages. That's the kind of market we want to be in.
