'Zombie' offices could turn into 400,000 new apartments for families. That's almost double the number of new US units in a typical year.

• The rise of remote work, high interest rates, and climate regulations all pose problems for office buildings.
• But the commercial real estate crisis could be a major opportunity to expand the US housing supply. 
• A new study found that more than 2,000 US office buildings could be converted into up to 400,000 apartments.

Lonely office buildings languishing away during the remote and hybrid work boom could have a new life — and it might mean your next apartment could be both good for the environment and your wallet.
