Developers are planning at least 30 affordable “Housing First” apartments for homeless people at the former site of Portland’s Oxford Street homeless shelter.

Avesta Housing, a Portland-based nonprofit affordable housing provider, has secured an option agreement to purchase the 1/3 acre parcel at 203 Oxford St., which was once Portland’s centrally located homeless shelter before the city closed it earlier this year to open a larger one in the Riverton neighborhood on the outskirts of Portland.

Pending municipal approval, the nonprofit will develop between 30 and 50 affordable apartments at the site with construction beginning in 2025, a spokesperson announced Monday.
