Transcript: Plans, Drawings & Required Documents

What documents do I need to submit?

The documents needed with your application will depend on the type of development.  They will need to show, clearly and in sufficient detail, your development proposals, what the development will look like when finished, how it will relate to the site and to adjoining structures and property etc.  If you are installing a septic tank, you may need to submit Trial Hole and Percolation test results.  If you are applying for certain types of agricultural development, you may need to submit signed agreements with landowners regarding effulent spreading.  The planning authority can clarify the documents and detail needed.

In general, however, you must always submit the following:

  • The page of the newspaper showing the newspaper notice
  • A copy of the site notice erected
  • 6 copies of the location map (at a scale of not less than 1:1000 in a built-up area and not less that 1:2500 in all other areas
  • A plan showing the position on the land of the site notice
  • 6 copies of a site layout plan (at a scale of not less than 1:500)

All maps must be in metric scale.

If the development applies to a protected structure or to the exterior of a structure within an architectural conservation area, the application must be accompanied by photographs, plans and other details, which will show how the development will affect the character of the structure.

What should a location map show?

A location map must show:

  • The Ordnance Survey sheet number of the map
  • The north point and scale of the map
  • The name and address of the person by whom it was prepared

What should a site or layout plan show?
