Breon says Vacasa is an "amenity" for luxury buildings, where residents might need extra space for guests: "It's a denser use of limited resources." And it's not just at Yard, but across the Willamette River at Park Avenue West, the 30-story downtown tower that opened earlier this year. It rents out 20 apartments through Vacasa and another four or six through short-term rental company Stay Alfred, according Vacasa and TMT Development, which manages Park Avenue West.
