Half of insured homes paid between $905 and $1,988. That is 20% more than the California median ($1,079). The most common flood zone for insured homes here is zone AO (36%).
This is what policyholders paid, not a quote. Two neighbors can pay very different prices: NFIP prices depend on the building (elevation, foundation, number of floors, replacement cost), the coverage and deductible chosen and the distance to water (FEMA FloodSmart: premium factors). For a price for your building, ask an insurance agent. Private flood insurance is not included in these figures.
