TSMC Signs On To NorthPark Rezoning Push

The land south of TSMC’s fab is heating up. Pulte Group and Taiwan Semiconductor Manufacturing Co. are pushing forward with a rezoning plan for 6,000 acres known as NorthPark. The proposal outlines housing, commercial districts, and preserved desert. At the heart of it is TSMC’s Innovation Core, a 900-acre section designed for future fabs and research.

Quick Points

• 6,000 acres of state trust land in play

• TSMC & Pulte Group aligned on rezoning

• Plan includes 15,150 homes across districts

• 900-acre Innovation Core tied to chip expansion

A Planned City Inside The Valley

NorthPark spreads across what locals call Biscuit Flats. The design carves out separate districts for homes, employment, and preserved land. Schools, trails, and apartments sit next to commercial nodes. TSMC’s Innovation Core anchors the center, setting aside room for research, suppliers, and possible fab expansions.

• 15,150 homes across all districts

• Detached single-family & rental units

• Seven mapped land use zones

• Large blocks of open space

• 900 acres of Innovation Core

The rezoning application has been filed with Phoenix. A city hearing will be scheduled, but the state land auction date has not yet been set.

Industrial Parks Build Momentum

North of NorthPark, Mack Real Estate is pushing forward on Mack Innovation Park Deer Valley. Financing of $89.25 million was arranged for Site C, which adds four completed industrial buildings. The entire project is planned for 2.6 million square feet once fully built.

• $89.25 million in new funding

• 584,665 square feet at Site C

• Planned three-phase industrial park

• Tenants in tech, logistics, & manufacturing

The location, near I-17 and Loop 101, positions it close to TSMC’s fab and Deer Valley Airport. The submarket has already attracted manufacturers, distributors, and consumer product firms.

Retail & Hospitality Plans Rise

Across Interstate 17, Vestar is working on Dove Valley Towne Center. The proposal covers 112 acres with hotels, retail, and fitness uses. The plan ties into the region’s push to provide services for workers, travelers, and new residents tied to semiconductor growth.

• Four hotels proposed

• More than 400,000 square feet of retail & dining

• Fitness & recreation facilities in plan

• Rezoning application filed with Phoenix

The site would complement residential growth and bring more commercial choices to north Phoenix.

Chip Growth Sets The Pace

TSMC’s Arizona campus is the driver. One fab is live. Two more are rising. Six total fabs are mapped for the site. Each expansion requires suppliers, workers, and infrastructure. Artificial intelligence growth keeps demand climbing, and that demand is reshaping The Valley’s development map.

• Six fabs projected

• Advanced packaging & R&D sites included

• Billions invested locally

• Direct demand tied to AI

Every major rezoning and project stacks onto that momentum. NorthPark and the Innovation Core mark the next phase.
