Wills: Does a Will Give Executor Power to Sale Real Estate

My question involves estate proceedings in the state of: California.
Does the executor of a will have the authority to sale real estate that belonged to the deceased person? I've had people tell me in California an executor can not sale real estate without it first going thru probate. I want my executor to be able to sale my house when I die and want to make sure I have things in order to allow him to do so without any issues.
Thank you
