What's Being Built in Ann Arbor
Track new construction, office expansions, and infrastructure projects shaping the tech corridor.
We track every major construction, lab, and mixed-use project in and around Ann Arbor that touches the tech and life-sciences economy. Each entry is built from primary sources: developer announcements, planning commission filings, Ann Arbor SPARK releases, and local reporting from the Michigan Daily, MLive, and Crain’s Detroit. Every project links back to its sources so you can verify the details for yourself.

Methodology
Status, square footage, and timeline figures come from the developer’s most recent public statement or the corresponding city planning record. Square footage and unit counts are reported as published; where ranges exist we use the midpoint. Spot a project we’re missing or a number that’s stale? Send us a note.
