> Couple that with the fact that office rents are higher per square foot than residential rents are, and you see why developers aren’t champing at the bit to get new projects underway. Van Nieuwerburgh gave me an example from San Francisco, where Juul’s old headquarters—down the block from Twitter’s improvised dormitory—is for sale for $150 million. That’s a lot less than the $397 million the embattled nicotine vape company paid for it in 2019. But at $400 a square foot to buy and another $400 a square foot to renovate, he said, the conversion would still produce a building with rents too high even for San Francisco. In other words, offices may be down, but they’ll have to fall a lot further before adaptive reuse becomes a bargain.
