This is Lawton Alternative Elementary School, located on 31st Ave at (surprise!) Lawton.
There are photos in the SFPL Historic Photo collection. I couldn't find exactly when the school was built, but it was in or just before 1937, judging by the captions on the photos.
The most interesting part is the entrance. There is tile on the walls and ceiling.
Years and years of patina on the doors.
This is looking to the right of the entrance.
There is an abundance of glass block.
According to the photos, there was an addition built in 1950.
