Hi Danny, that's a great block of S Norton between County Club and Pico.
The city gives 4019 as the official address of your corner building (the other addresses, 4013-4027, are probably for individual shops). The permit for new construction is dated 10 Feb 1927. No. 4019 was purpose built for "stores and offices" (later permits refer to the building's use as "Public Assembly"). The New York Finance Company is listed as owner. Albert C. Martin, Sr was the architect (Martin's wiki page is
here if you're interested). A.C. Martin's offices were in the Higgins building at W 2nd Street and Main, DTLA, in 1927. The firm he founded is still in business.
The former sign on the back of the building is in the typeface which Bank of America used years ago. Bank of America was listed as owner in 1949 when they got a permit to add their signage to the front of the building. Before that, in 1941, there was a Farmers and Merchants Bank branch at this address

Someone was
shot and killed at No. 4019, during a party in 2000 (that can happen anywhere).
Here's a 1921 Baist real estate map of your block in 1921. There were more empty lots than built ones!

The mixed-use building on the other side of S Norton looks interesting too. It went in in 1925 and houses
"Jewel's Room" and "Jewel's Catch One":
