[1][2] The building was modernized in 1974, and in 1979, when the Broadway Theater and Commercial District was added to the National Register of Historic Places, Hass Building was listed as a non-contributing property in the district.

[3] In 2009, Haas Building was converted into 68 apartment units, including a rooftop penthouse.

In the building's early years, it was the location of so many realty buyers, sellers, leasers, and lessees, that it was said to be "an excellent place to diagnose financial conditions in and around Los Angeles."

During December 1915, the Bank of Italy secured a 25-year lease on the ground floor and the basement of the building, with 6,550 feet (2,000 m) of ground floor space and safe deposit and coin vaults in the basement.

Despite this, a small portion of the original terra cotta is still visible on the 7th Street facade.
