what is exempt development?
CAN I BUILD AN EXTENSION WITHOUT PLANNING PERMISSION?
Subject to site location, planning history and particulars, small scale domestic extensions, including conservatories, may not require planning permission if the extension is to the rear of the house and complies with the following:
- The original floor area of the house is not increased by more than 40 square metres. It is important to note that where the house has been extended before, the floor area of the extension you are now proposing and the floor area of any previous extension, including those for which you got planning permission, cannot exceed 40 square metres
- For terraced or semi-detached houses, the floor area of any extension above ground level does not exceed 12 square metres, this includes any previous extensions carried out
- Any extension above ground floor level is at least 2m from any boundary
- Any extension does not exceed the height of the house
- Any extension does not reduce the area of private open space, reserved for the occupants of the house, to the rear of the house to less than 25 square metres.
There are also restrictions in relation to the height allowed in such an extension. These are that:
- If the rear wall of the house does not include a gable, the height of the walls of the extension must not exceed the height of the rear wall of the house
- If the rear wall of the existing house has a gable, the walls of the extension (excluding any gable being built as part of the extension) shall not be higher than the side walls of the house
- In the case of a flat roofed extension, the height of the highest part of the roof may not exceed the height of the eaves or parapet. In any other case, no part of the new roof may exceed the highest part of the roof of the house
- A gable is the upper part of a wall (normally triangular), between the sloping ends of a pitched roof.
There are also restrictions relating to the required distances between windows in extensions, the facing boundary of the adjoining property and the use of the roof of the extension. These are:
- Any windows proposed at ground floor level as part of an extension should not be less than 1 metre from the boundary they face
- Any windows proposed at above ground level should be not less than 11 metres from the boundary they face
- The roof of any such extension should not be used as a balcony or roof garden.

Also under Section 5 of the Planning and Development Act, 2000 (as amended), a person can seek a formal declaration from the planning authority to establish if there is a requirement for planning permission for a specific proposal. You must complete the form P07 Application form for a declaration on development and exempted development (Section 5) and submit it to the planning authority along with a site location map and a fee of €80.00. You may include drawings, photos etc. If no further information is required, a decision will issue in four weeks from receipt of the request.The applicant may appeal the decision to An Bord Pleanála.
the CRITERIA are set out below
Max 4m from rear wall for a detached house
Max 3m from rear wall for all other houses
(Rear wall as built in 1948. Other extensions are included in the length allowed)
Max 4m from highest ground on site
Max 3m when within 2m from boundary wall
With these generous length and height allowances, you can effectively gain a new room to the rear of your property, and one in your loft space too
40 sqm allowable for terraced homes and 50 sqm for Semi and Detached homes
Must match the existing property
If the extension roof is pitched, it should be a similar degree to the original roof
No extensions can overhang a boundary wall
No balconies, verandas, raised platforms or chimneys
No Flats or dividing a property to multiple residences
These need a Full Planning Permission Application, which is a similar and straightforward process but just a more lengthy application form
We can help with these too
when is the deadline?
There is no deadline for Permitted Development!
For the Larger Home Extension Scheme, which allows double the above dimensions, construction must be completed by May 2019
..And my neighbours' Opinions?
The Planning Authority, or Council, write to inform your neighbours and any other owners under the Neighbour Consultation Scheme. They have 21 days to comment or object
We can advise strategies to help the process to flow smoothly
is this permission for everywhere?
Not for Conservation Areas, National Parks, Areas of Special Interest, or areas where the Council have issued an Article 4, which prevents Permitted Development being allowed due to the sensitive nature of the Area
But it is for most areas!
