When you no longer need a Microsoft SharePoint site – such as a site created for a specific project – it should be deleted to ensure only relevant content can be found.
You must be a site owner or SharePoint administrator to delete sites. If you are a site owner but you are unable to delete a site, your administrator may have turned off the ability to do so.
Notes:
When you delete a communication site or team site, you also delete any pages, content, and user information including documents, document libraries, and lists.
Sites associated with a hub can be deleted like any other site.
When you delete a group connected team site, there can be a delay before the site is removed from SharePoint.
Delete a communication site or team site
When you delete a team or communication site, you also delete any subsites, content, and user information that are part of the site, including documents, document libraries, lists, and list data.
Navigate to the team site or communication site you want to delete.
Select Settings at the top of the site and then click Site information
Note: If you do not see Site information in the Settings panel, work with your SharePoint administrator to get access.
At the bottom of the Site Information panel, select Delete site.
Check the confirmation box, and then select Delete.
