That is technically true, but not really true. The basic tax rate is indeed 1%, but counties and cities are free to add any kind of fees they want (AFAIK there is no limit) to your property tax so in practice you're paying way more than 1% in CA.
That is the loophole they use. They add all kinds of fees into the property tax but don't classify them as taxes. Best I know, there is no limit to how many and how much. Twenty years ago my property tax was just a single line item, the property tax. Now it's up to 6-7 (don't have the bill in front of me to check exact count) line items.
So yes, your CA propery tax^H^H^Hfee bill can be way over 1%
