THE MARKET · INDUSTRIAL WORKSPACES

Demand has outrun supply.

Traditional developers build for large logistics users, leaving small businesses with few places to grow. Small bay industrial (space under 50,000 square feet for trades, contractors, and light industrial users) has some of the lowest vacancy in the sector. Demand from these businesses keeps rising while new supply lags behind. That gap is where Mainstreet invests.
