The multiple barriers to converting office space into housing units

Henry Grabar details the many issues in switching office space to living space:

What’s going on? One problem is simply with the shape of office buildings: Their deep floor plates mean it’s hard for natural light to reach most of the space once it’s divided up into rooms. Their utilities are centralized, which requires extensive work to bring plumbing and HVAC into new apartments. Either way, they require significant architectural intervention. The older stock of prewar offices, which are better suited for residential units, have often already been converted in cities like Chicago and Philadelphia. Another issue is with zoning codes that bar housing from office districts. A third obstacle is the building code: Early residential conversions, like those in SoHo’s lofts, were usually illegal, sometimes for complicated reasons that seem less important than mandating a window in every bedroom.

What’s more, business districts don’t empty out building by building but with vacancies here and there across the skyline. You wouldn’t convert Twitter’s building, since it’s partially occupied by workers. So, in one sense, Musk’s bed stunt is an example of his already innovating at Twitter. Very mixed-use! “You’re not going to run into a building that’s 100 percent empty, ready to be converted,” said Anjali Kolachalam, a researcher with Up for Growth. She recently ran office space in downtown Denver through a filter to find good conversion targets—tall buildings with high vacancy rates and small floor plates built before 2010. She wound up with just 4 office buildings, out of the 208 total.

Finally, converting buildings to residential use is expensive. 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.

While the challenges are present, I wonder if someone has this figured out – this could be a company, developer, or community. Are there ways to quickly address the issues listed above or does it require a sustained effort? Imagine someone figures this out and there is a way to make some cool conversion from an exciting work space (if this is possible) or name to an interesting housing unit. If this can happen for churches and religious buildings, why not for office buildings?

If this does not work easily now, could we anticipate new buildings that could more easily switch between uses? There are ways to plan, zone, and build with more flexibility in mind so that adjustments could be made given needs and market conditions. Would it cost more to construct a building in this way? If so, perhaps the possible higher occupancy rates and the ability to adjust could bring in more money in the long term.
