The Anti-Defamation League (ADL) was the bill's lead sponsor, after receiving a number of complaints from Jewish renters and condo owners who were told to remove their mezuzot because of landlord policy.
“Enforcement of otherwise neutral and generally applicable rules that prohibit altering the appearance of an exterior doorway has posed a unique hardship for some Jews in California who have been ordered to remove their mezuzahs or face a daily fine,” ADL California Legislative Director Nancy Appel said.
“Although ADL has successfully advocated for affected Jews to enable them to post their mezuzahs, this bill guarantees that they won’t have to face this impossible dilemma in the first place.”
Senator Ben Allen, Jewish Caucus Chair, was also a lead sponsor of the bill. He worked with several faith-based organisations, including the Hindu American Foundation, which requested an increase in the minimum size to meet religious needs.

The bill was signed into law by California Governor Gavin Newsom during the summer recess, with Jewish legislators celebrating on their returned to the state senate.
Five other US states — Connecticut, Florida, Illinois, Rhode Island and Texas — already have similar laws in place, the ADL said.
Last year the JC reported that residents in an apartment block near Stamford Hill were told by their management agency to remove their mezuzot.
The management agency later apologised.
