Office-to-Apartment Conversions 2026: 90,300 Units Are Reshaping the U.S. Housing Market

# Office-to-Apartment Conversions 2026: 90,300 Units Are Reshaping the U.S. Housing Market

> **Quick answer:** Office-to-apartment conversions reached 90,300 planned units at the start of 2026 — a 28% year-over-year jump and a 291% increase since 2022. Empty office buildings, permanently altered by hybrid work, are being transformed into downtown apartments at the fastest pace in U.S. history. New York, Washington D.C., Chicago, and Philadelphia are leading the wave. A landmark Pew Research analysis found co-living conversions deliver 3.9 times more affordable homes per subsidy dollar than traditional construction.

The office-to-apartment conversions trend in 2026 has become the most dramatic real estate reshuffling since the post-pandemic migration wave. With national office vacancy hovering at 22%, developers are doing the math: empty floors cost money, but apartments in walkable urban cores are in intense demand. The result is a pipeline of 90,300 units that is simultaneously solving a housing crisis and rewriting the geography of American cities.

## The Numbers: How Big Is the Office Conversion Boom?

The scale of the transformation is hard to overstate. According to RentCafe data analyzed by Smart Cities Dive, the office-to-apartment conversion pipeline hit 90,300 units at the start of 2026 — up 28% from a year earlier and up a staggering 291% compared to 2022. Office buildings now account for nearly 50% of all adaptive reuse activity nationwide, surpassing hotels (18%) and industrial buildings (16%).

Avison Young, the commercial real estate services firm, separately tracked the removal of 111 million square feet of office space from national inventory in a single quarter — a figure that represents entire city blocks worth of space leaving the office market permanently.
