Amending development applications
Following the issue of development approval, applicants sometimes seek to amend the approval or, in circumstances where they have been unable to commence the development, they may request an extension of time.
The Planning and Development (Local Planning Schemes) Regulations 2015 allow landowners to apply to amend a previously granted planning approval.
