Showing my house to new prospective tenants

[Patrick Thomas Dickinson]

Hi everybody, my current tenants gave me a months notice yesterday stating that they will be vacating by October 6th, 2021.  It is written in my lease that I can show the house to prospective tenants if needed. I am in California any idea on how much notice to give my current tenants before showing the house, I believe its 24 hours. I am thinking I might just schedule a couple days of open house and have people come during there scheduled time slots. Any thoughts people.
