ADU · 731 21st Avenue, San Francisco

A one-bedroom garden apartment, on the ground floor

In design · progress set 11/10/26

We're turning the storage space behind the garage into a one-bedroom apartment that opens onto a private terrace in the back garden. The two flats upstairs don't change. The work is new interior walls, plumbing and electrical, plus some structural changes: a few enlarged openings and a couple of new windows. It's being permitted as a State ADU.
