Today, I will explain you about How to Add Permission Levels Using Powershell in SharePoint 2013.Besides using PowerShell to switch or adding list permissions, you’ll additionally add new Permission Levels. As permission levels don’t persist within website templates, this will be handy once making deployment scripts for brand new sites.
Here’s however you do it:

# Add Permission Level to a site $spSite = Get-SPSite "http://youwebsite.com" # We'll assume the list is in the top-level site in the site collection $spWeb = $spSite | Get-SPWeb # In this example, we add a new Permission Level labelled "Add Only" to the site, which will allow users to only add new items (no editing or removing) if($spWeb.RoleDefinitions["Add Only"] -eq $null) { # Role Definition named "Add Only" does not yet exist $spRoleDefinition = New-Object Microsoft.SharePoint.SPRoleDefinition $spRoleDefinition.Name = "Add Only" $spRoleDefinition.Description = "Can only Add items. Use this Permission Level for List or Library Permissions." # .Type is a ReadOnly property, hence it'll remain on "None". # Use the command [System.Enum]::GetNames("Microsoft.SharePoint.SPBasePermissions") to get a list of possible BasePermission values # For this Permission Level, we'll add four base permissions: $spRoleDefinition.BasePermissions = "ViewListItems, AddListItems, Open, ViewPages" $spWeb.RoleDefinitions.Add($spRoleDefinition) } #Display the properties for our new Permission level $spWeb.RoleDefinitions["Add Only"] | Out-Host $spWeb.Dispose() $spSite.Dispose() |
Unfortunately, the RoleDefinition.Type property, that contains a RoleType Enum value, is Read-Only. Hence, it’ll get the default value “None”.
The .BasePermissions Property could be a flags attribute that contains the particular permissions granted to users and groups assigned with the permission level. See MSDN for a description of those Permissions, or use the following command to enumerate them in PowerShell:
