The city has received a large response to its call for “micro-unit” apartments, from major luxury housing builders to those known for creating smaller, innovative projects

…”in terms of the boxes you had to be able to tick off,” said Jerilyn Perine, executive director of the nonprofit Citizens Housing and Planning Council, which championed the micro-unit idea.

“The financial side is really the big challenge here,” Ms. Perine added. “The city didn’t dictate that many things. They said, ‘You think about the acquisition price, the amount of affordable units, the amount of market-rate units and the rent.'”
