Demolition Guide Ireland: Do I Need Planning Permission?
Short answer: if it is a habitable house, yes. Demolishing a house in Ireland requires planning permission from your local authority. Some smaller structures are exempt, but the exemptions are narrower than most people expect, and getting it wrong is expensive.
The short version
Check what you are demolishing. Habitable house, terrace, protected structure or ACA means permission is required. No exceptions for rebuilding on the same footprint
Sheds, garages and outbuildings within the curtilage of a house are often exempt, but conditions apply
If you are not sure, apply for a Section 5 Declaration. A few hundred euro for a written ruling from the council on whether your demolition is exempt
Check the Record of Protected Structures and whether the site is in an Architectural Conservation Area, before anything else
Apply for the demolition together with the replacement build. Councils want to see what the site becomes, not just what is removed
Allow three to six months from lodging to starting on site. Eight weeks for a decision, four weeks for appeals, longer if further information is requested
Get the surveys moving in parallel. Asbestos survey on anything pre-2000, bat survey on older or rural buildings
Arrange utility disconnections early. ESB Networks, Gas Networks Ireland, Uisce Éireann. These are a common cause of delay
Appoint your PSDP and PSCS. These are your duties as the client under the Construction Regulations
Plan the waste. Demolition waste goes to authorised facilities via permitted collectors, and you keep the dockets
Now the detail.
When you definitely need permission
Planning permission is required to demolish:
A habitable house. Whether it is lived in, vacant or derelict. If it was built as a dwelling and could function as one, it counts
Any building forming part of a terrace. Even a small one, because taking it out affects the structures either side
A protected structure, or any building within the curtilage of one
Anything in an Architectural Conservation Area
Most commercial and industrial buildings
It is worth saying clearly, because it catches people constantly: the fact that you are rebuilding on the same site does not make the demolition exempt. In practice the demolition and the replacement dwelling are applied for together as one application.
When you might not need it
Certain demolitions fall under exempted development in Schedule 2 of the Planning and Development Regulations. Broadly, that covers the demolition of buildings other than habitable houses, typically:
Sheds, garages and outbuildings within the curtilage of a house
Some agricultural structures
Small non-habitable structures
But the exemptions come with conditions, and they fall away entirely if the building is a protected structure, sits in an ACA, or forms part of a terrace.
They also fall away if there is a planning condition on the original permission that restricts demolition, which is common on newer estates.
If you are not sure, get a Section 5 Declaration
This is the part most people do not know about and it is the single most useful thing in this article.
Under Section 5 of the Planning and Development Act 2000, you can apply to your local authority for a formal declaration on whether what you propose is or is not exempted development.
It is a fraction of the cost of a planning application
You get a written determination you can rely on
It takes weeks rather than months
If you disagree with the outcome you can refer it onwards
If there is any doubt at all about whether your demolition is exempt, this is the route. A written declaration costs a few hundred euro. Demolishing something you were not entitled to demolish costs a great deal more than that.
Protected structures and conservation areas
If the building is on the Record of Protected Structures, or sits in an Architectural Conservation Area, treat it as a different category of job entirely.
Demolition of a protected structure is rarely granted and where it is, it usually comes with heavy conditions, recording requirements and often partial retention of facades or features.
You will likely need a conservation architect involved from the start, and an application that sets out why the structure cannot reasonably be retained.
Check the Record of Protected Structures in your local authority’s development plan before you do anything else. It is public and it is searchable.
How to apply
Demolition permission follows the standard planning process.
Drawings and a site layout showing what is being removed
A demolition method statement, sometimes required depending on the site
Site notice erected and a newspaper notice published
Application lodged with the local authority
Fee paid
Almost always this is submitted as part of the application for whatever is replacing the building, because the council want to see what the site ends up as, not just what is being taken away.
How long does it take?
Allow for the full timeline, not just the decision.
8 weeks for the local authority decision, assuming no further information is requested
Further information requests are common and add months
4 weeks after the decision for third party appeals
Appeals to the national planning appeals body add months again
Realistically, from lodging to being able to start, three to six months is a fair expectation on a straightforward application. Longer if anything is contested.
That is why the planning question is the first thing to settle, not the last.
What happens if you demolish without permission
This is unauthorised development, and the consequences are real.
The local authority can serve an enforcement notice
Prosecution is possible, with substantial fines
You can be required to reinstate, which on a demolished building is both extraordinarily expensive and often impossible
The site becomes very difficult to sell, because it will not pass a conveyancing search
Any future planning application on the site starts from a bad place
Retention permission exists, but it is not a safety net. There is no obligation on a council to grant it, and applying for it tells them exactly what you did.
Nobody sets out to do this. It happens when somebody assumes a derelict cottage or an old outbuilding does not count, and knocks it on a Saturday.
Planning is not the only thing you need
Permission is the first hurdle, not the only one. Before any building comes down in Ireland you will typically also need:
An asbestos survey, a refurbishment and demolition survey, on anything built before 2000
A bat survey on older or rural buildings, since all bat species are protected under the Wildlife Acts
Utility disconnections confirmed in writing from ESB Networks, Gas Networks Ireland and Uisce Éireann
PSDP and PSCS appointments under the Construction Regulations, which are duties falling on you as the client
A waste plan, with demolition waste going to authorised facilities via permitted collectors
Each of these has its own lead time and several of them run in parallel with the planning application rather than after it.
