Is a net salary of $145k enough to survive in San Francisco for a family of four?

My family and I have all accepted jobs in the city that will total this amount and just want to know what the rents are going for and what won't eat at least half of our paychecks.

We would prefer a nice 2-3 bedroom in a safe, desirable area, if not in excess of $5,000 if possible.
