By the numbers: In 2020 and 2021, a whopping 13,250 apartments across the country have come from repurposed offices, per a new report from RentCafe.

Former office buildings make up 41% of the apartment conversion market, which also includes old hotels, warehouses, factories and even hospitals.

It’s a sign of the times. As the pandemic normalizes remote work, lots of firms — from startups to multinational corporations — are downsizing their offices. A logical new purpose for these centrally located buildings with big parking lots is housing.

Repurposing old buildings as apartments is easier on developers, too. The renovations can cost up to 40% less than a new construction, per RentCafe’s report.
