No, it is just the capital gains rate for Federal.
However, the tax on the depreciation is taxed at your regular tax rate, up to 25%. The rest of the gain is usually taxed at 15%. I think California treats it all as regular income.
However, that 'extra' income may affect other things on your tax return, such as the 3.8% Net Investment Income Tax and some credits and/or deductions could be reduced.
For example, let's say you bought the property for $100,000, took $20,000 of depreciation, sold it for $150,00, and did not make any improvements to the property. The $20,000 of depreciation is usually taxed at 25%, and the other $50,000 gain is usually taxed at 15%. Plus State taxes, plus that 'extra' income could affect other things on your tax return.
