➤ Key Highlights
90,300 apartment units in office conversions in 2026 — a ~28% YoY increase, a new record.
Office now accounts for ~47% of all adaptive-reuse activity nationally.
New York, Washington D.C., and Chicago lead the active pipeline.
25 Water Street (~1,300 units) is the largest office-to-resi conversion in NYC history; Yellowstone secured $203M to convert the Candler Building (176 units).
The 47% share is the structural number — adaptive reuse used to mean hotels and industrial; it's now majority office.
The math finally closes.
➤ SIGNAL
Three things had to line up: ground-up construction costs stayed high enough to make conversion competitive, obsolete Class B/C office basis reset low enough to pencil, and conversion incentives matured in the lead cities. They have. What was a one-off press release in 2023 is a repeatable supply channel in 2026.
The constraint is no longer zoning — it's geometry and basis. Only floor plates with the right depth, light, and core placement convert economically, which is why roughly 10–15% of office stock is realistically in scope, not the whole vacant tower count.
Implications This is a rare two-sided win: it removes obsolete office from supply (helping office vacancy at the margin) while adding housing. But it's selective — underwrite the floor plate and the basis, not the headline vacancy.
➤ TAKEAWAY
Conversion is no longer a narrative — it's a supply channel with a unit count.
