This is intended as a practical guide. It is not a definitive legal interpretation of planning law. For more information you should consult your planning authority.
Generally, you need planning permission for any development of land or property unless it is specifically exempted from this need. The term development includes the carrying out of works (building, demolition, alteration) on land or buildings, and the making of a material (i.e. significant) change of use of land or buildings.
Exempted development is development for which planning permission is not required. Categories of exempted development are set out in planning law. Relevant exemptions in relation to domestic developments are outlined in this leaflet. There are usually certain thresholds relating to, for example, size or height. Where these thresholds are exceeded, the exemptions no longer apply. The purpose of exemption is to avoid controls on developments of a minor nature, such as small extensions to houses.
Yes. Where a change of use is not âmaterialâ, planning permission is not required. (See Q3 PL.7)
This depends on the circumstances of each situation. Generally, any change of use of a substantial nature which has an impact or potential impact on neighbours or the local community will need planning permission.The planning authority can give advice on whether it considers any particular change of use is significant enough to be âmaterialâ for planning purposes. See Question 19 below for details of how to resolve a question whether a development is or is not exempted.
Small scale domestic extensions, including conservatories, do not require planning permission if the extension is to the rear of the house and comply 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 less than 25 square metres.
There are also rules about 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 rules about 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..
The conversion for use as part of a dwelling house (e.g. as a living room or bedroom) of a garage, store, shed etc. attached to the rear or side of a house is normally exempted development, subject to the 40 square metre limit and conditions as set out in Question 5 above.
Note: You should contact your planning authority if you are unsure of any of the above conditions in relation to any proposed extension.
You can build a garage, carport, shed, greenhouse, kennel for domestic pets etc., as long as it does not extend out in front of the building line of the house and does not exceed 4 metres in height, (if it has a tiled or slated pitched roof), or 3 metres (if it has any other roof type). The floor area limitation for exempted development is 25 square metres. The structure may not be lived in, used for commercial purposes or for keeping pigs, poultry, pigeons, ponies or horses. Garages, sheds etc. to the side of the house must
match the finish of the house. You cannot reduce the open private space, reserved exclusively for the use of the occupants of the house, at the side or rear of the house below 25 square metres.
You can build a porch without planning permission, as long as it does not exceed 2 square metres in area and is more than 2 metres from any public road or footpath. Where the porch has a tiled or slated pitched roof, it must not exceed 4 metres in height, or 3 metres for any other roof type. A front porch within these limits is the only type of development allowed to extend beyond the front wall of the building (the building line) and still remain exempted.
Capped walls made of brick, stone or block with a decorative finish, railings and wooden fences, but not a metal palisade or security fences, can be erected as long as they do not exceed 1.2 metres in height in front of your house or 2 metres at the side or rear. If the wall is made of plain blocks or mass concrete it must be rendered or plastered. Gates and gateways may be built or replaced providing they do not exceed 2 metres in height. You will need planning permission if you wish to make a new or wider access to the public road.
A boiler house or a chimney for a central heating system, or an oil storage tank (up to 3,500 litres capacity), is exempted development.
Car parking spaces, hard surfacing, garden paths, garden ponds and patios etc. are exempt once they are not more than 1 metre above or below existing ground level. There are no other limitations to the rear of the house but no more than 2 car parking spaces to the side or front of the house are exempt.
A radio or TV aerial on your roof is exempt once it does not exceed 6 metres in height above the roof. A satellite dish up to 1 metre across and below the top of the roof is exempted development only to the rear or side of the house. Only one dish may be erected on a house. A dish to the front needs permission.
You can carry out any internal alteration you wish as long as you do not alter the domestic use of the house. External works of repair, maintenance and improvement such as painting or replastering do not need planning permission so long as they do not materially affect the external appearance, thus rendering the appearance inconsistent with neighbouring buildings. You may need approval for certain external alteration e.g. a new connection to a sewer.
This exemption does not apply to protected structures, nor to the subdivision of a house into flats or granny flats. Planning permission must be obtained for such works.
You can demolish without permission a building other than:
⢠a habitable house, or;
⢠a protected structure or a proposed protected structure;
⢠a building in a terrace, or one which is attached to another building in separate ownership. However, it does not automatically follow that you will get permission to build a replacement. A habitable house is a house which is:
⢠used as a dwelling;
⢠is not in use, but when last used it was a dwelling and is not derelict; or
⢠is provided for use as a dwelling but has not been occupied;
⢠it also includes a building where the last permitted use was as a house, even if it has been in unauthorised use since then.
One caravan, one campervan or one boat may be stored in your garden for up to 9 months of the year as long as it is not lived in or used for business purposes.
You do not need permission for domestic advertisements up to 0.3 square metres in area, such as your house name or number and âBeware of Dogâ type signs. If selling or letting your house the size increases to 0.6 metres but only one advertisement is allowed and it may not be left up any longer than 7 days after the sale or letting.
All forms of development which are normally exempted lose this status and require planning permission if they:
⢠contravene a condition of a planning permission;
⢠endanger public safety by causing a traffic hazard or obstructing the view of road users;
⢠build forward of the building line (except in the case of small porches);
⢠involve a new or wider access to a public road;
⢠affect a building, feature, site, character of landscape, view of special amenity value or special interest, etc., (check your local development plan);
⢠obstruct a public right of way;
⢠are not wholly related to the use of the house for domestic purposes;
⢠involve development within a special amenity area;
⢠involve development to a protected structure;
⢠include any works to, or changes to, an unauthorised structure, or one where there is an unauthorised use. (âUnauthorisedâ means without the benefit of planning permission or exempted development status).
The exemptions listed above at 5, 7,8, 10, 11, 12 and 15 do not apply in the case of flats or apartments and the provision of car parking is only exempt when to the rear.
The full list of exempted developments is set out in the Planning Acts and Regulations (details at the end of this leaflet). The planning authority can advise on whether they consider planning permission is necessary, or not, in a particular case. If you disagree with the planning authority on whether planning permission is needed, you can obtain a formal ruling by referring the decision to An Bord PleanĂĄla on payment of the appropriate fee. Further information is available directly from the Board at 64 Marlborough Street, Dublin 1, Telephone (01) 8588100.
The limits must be observed and the planning authority has powers to stop the development if they are breached. If, due to an oversight an error is made, you should apply to the planning authority for permission to retain the work done. This is generally known as âretentionâ permission. It does not automatically follow that this will be granted. This fee for a retention application is 3 times more than the standard fee and you may have to take down, alter or rectify work done, which can be costly. Prosecution for breaches of planning law can result in heavy fines or imprisonment. You may also find it difficult to sell property which does not comply with planning requirements. If buying property check that the building itself and any extensions or alterations comply with planning requirements or you, as the new owner, may be liable to enforcement action.
If you have any doubts or queries on any planning aspect you can contact the planning authority. See also Question 23 in relation to Building Regulations.
You should contact your local E.S.B. office (see PL. 6 Paragraph13) if your proposed works are near existing electricity lines, if there is a question of clearance heights under power lines or if the construction work will bring anyone within reach of the electricity supply to your house. In fact, you must do so where any overhead lines come within 6 metres of the construction works.
Your development must be in accordance with the building regulations. These regulations set out the basic design and construction requirements and apply to all new buildings, extensions, alterations and certain changes of use of existing buildings. Details of the building regulations and of the associated procedures are available in PL.11 – A Guide to the Building Regulations. Further information may be obtained from your local authority. You may also need other types of approval e.g. making a new connection to a sewer. Contact your local authority in such cases.
This is not a legal requirement for exempted development. However, it is in your interest to let neighbours know about work you intend to carry out to your property. They are likely to be as concerned about work which might affect them as you would be if the roles were reversed. You may be able to meet some of your neighbourâs worries by modifying your proposals. Even if you decide not to change, it is usually better to have told your neighbours before the building work starts. If you or your contractor need to go on to a neighbourâs property, you should obtain his or her consent before doing so. Alterations or additions to your house may make it more vulnerable to burglary. Your local Garda Station can provide helpful advice on ways of reducing risk.
