Azure Privileged built-in role
Owner
Grants full control-plane management of Azure resources at the assigned scope and can create or delete Azure RBAC role assignments. Owner is one of Azure RBAC's broadest privileged administrator roles and is not a least-privilege default.
Role-definition permissions are imported from Microsoft Learn. Practical scope, use cases, prerequisites, best practices, security considerations, assignment guidance, and relationships have been reviewed against the official sources below.

Practical scope
The built-in definition is available throughout the Azure hierarchy. An Owner assignment affects the selected management group, subscription, resource group, or resource and is inherited by child scopes. The definition has no DataActions, so it does not itself grant Azure RBAC data-plane operations, although it can grant roles that do.
Common use cases (2)
- Administer both Azure resources and Azure RBAC access within a deliberately bounded scope.
- Maintain subscription ownership when the same trusted administrator genuinely needs full resource management and access delegation.
Prerequisites (2)
- Confirm that the assignee needs both broad resource management and role-assignment authority; otherwise select a narrower role.
- The assigning administrator needs Microsoft.Authorization/roleAssignments/write at the target scope.
Best practices (3)
- Keep no more than three subscription owners, as recommended by Microsoft.
- Remove unnecessary Owner assignments and prefer job-function roles or a dedicated access-administration role.
- Use the narrowest scope, add a role-assignment condition when delegation can be constrained, and use PIM for eligible human access where available.
Security considerations (3)
- An Owner can change or delete all Azure resources in scope and grant itself or others additional Azure roles.
- Compromise at a management-group or subscription scope exposes every inheriting child scope.
- The absence of DataActions does not make Owner low risk because its control-plane and access-delegation authority are unrestricted.
Assignment guidance
Reserve Owner for a very small number of trusted administrators who need both resource control and access delegation. Use Contributor for broad resource management without RBAC delegation, or Role Based Access Control Administrator for access administration without broad resource writes. Prefer eligible PIM access for people.
