How do california property taxes change?

Glynis
I'm thinking of refinancing my house, will my taxes change? I live in LA county.

Refinancing your mortgage will not affect your property taxes. Property taxes are based on the value of the property, not the amount owed.

I believe that it happens when you purchase a home.Or make a big improvement (add a pool, add a floor, add a room).
