I've lived in a variety of areas across the west coast. In all of them, rural to dense city environments... things were stolen. I've had multiple bikes stolen, my car, my backpacks, my eye glasses (yes - that is weird), and more... And they were all in a variety of areas. I still classify many of those areas as "safe" and so do many reports but theft still happens.

Almost nowhere is "safe" from thieves. If you live in a "nice area" like any of the more expensive neighborhoods/cities in the bay area then you're very prone to burglary because go figure you likely have expensive stuff that's good for stealing. Unless you have really good defense mechanisms to detour/stop thieves (or just nothing worth stealing) then you're going to get stuff stolen.

Property crime isn't the same as violent crime.
