SharePoint Home Site is a new feature available in modern SharePoint that allows you to designate a given site as a Home Site for the whole SharePoint Intranet. By doing so, you formally label/authorize a site to be THE MAIN SITE of the portal.

It should not be confused a start page. SharePoint Start Page is an out of the box page that just tracks the sites you follow, regularly visit, etc.

Important Notes first

  • You can only turn a Communication Site into a Home Site. You cannot turn any other type of site into a Home Site (i.e., Team Site).
  • You are only allowed to have 1 (one) Home Site at a time.
  • You cannot turn a Communication Site that is associated with a Hub into a Home Site. It has to be either a standalone Communication Site or a Communication Site that is registered as a Hub Site.
  • You can turn a site into a Home Site only via PowerShell.
    Set-SPOHomeSite -HomeSiteUrl https://domain.sharepoint.com/sites/yourcommsite

How to unregister a site as Home Site

  • If you want to switch Home Site to a different site (since we can only have one home site at a time), just run 
    Set-SPOHomeSite -HomeSiteUrl https://domain.sharepoint.com/sites/yourcommsite 
    PowerShell command again, putting a new Communication site URL in place of https://domain.sharepoint.com/sites/yourcommsite
  • If you do not want to have any Home Sites in your tenant, you can run the following command in PowerShell: 
    Remove-SPOHomeSite
