How Long Does the Planning Permission Process Take in Ireland?
If you're planning to extend your home, build a garden room, or carry out a bigger renovation, one of the first questions you'll probably ask is how long will the planning process take?
While the timeline can vary depending on the type of project and whether any objections arise, most standard domestic planning applications follow a clear process with specific timeframes. For straightforward applications, it usually takes 12 weeks from lodgment to get a final decision.
Here’s what you can expect, step by step, when applying for planning permission in Ireland.
🪧 Step 1: Public Notices
Your application officially starts when you:
Erect a site notice — a sign on or near the entrance to your property clearly stating what you plan to build, and
Publish a newspaper notice — in an approved local or national newspaper.
This starts the clock — you have just two weeks from these dates to submit your application to your local planning authority. If your application isn’t submitted within those two weeks, you’ll need to put the notices up again.
💡Tip: Check with your local council which newspapers they accept and what formatting they require for notices.
📬 Step 2: Observation Period (Weeks 0–5)
Once your application is submitted, a 5-week observation window begins. During this time:
Anyone can make a submission commenting on your proposal (with a €20 fee). These are often called objections, but they’re not always negative.
The planners may begin an initial review of your application. This often includes a visit to your project site to check the site notice is in place, and they may ask for access to your property.
This stage allows neighbours, community groups, or other interested parties to have their say — especially if your project affects boundaries, privacy, parking, or streetscape. The planning authority cannot make a decision until this 5-week period is over.
📄 Step 3: Council Decision (Weeks 6–8)
Once the submission period ends, your local council usually takes 3 weeks to notify you of their decision, which will be either:
✅ Grant permission, often with conditions,
❌ Refuse permission, giving reasons why, or
🛑 Request Further Information (FI) if your application is unclear, missing something, or should be altered in some way.
🗓 In the best-case scenario, you’ll have this decision around 8 weeks (2 months) after submitting your documents.
💡 Objections don’t automatically cause delays — even if there are submissions, planners aim to issue decisions within the same timeline unless more information is needed.
⚖️ Step 4: Appeal Period (Weeks 9–12)
Even after a decision is issued, there’s a 4-week appeal period. During this time:
Anyone who made a submission (including you) can appeal the decision to An Coimisiún Pleanála (formerly An Bord Pleanála),
No work can begin until this period has passed without any appeal,
If no appeal is made, the planning authority will issue you with a Final Grant of Permission.
❗Important: You cannot legally begin construction until the appeal window has closed and the Final Grant has been issued.
🚧 After Approval: Getting Started
Once permission is final and in hand, you can begin your build as long as:
You stick to the approved plans,
You follow any conditions attached (e.g. materials, boundary treatments, or ecology measures),
You comply with building regulations and building control (which are separate from planning permission).
Planning permission is normally valid for 5 years, though you can sometimes apply to extend it under specific conditions.
🛠️ What Can Delay the Process?
While the typical process takes around 12 weeks, some applications take longer due to:
🔄 Further Information (FI) Requests
If your application is incomplete, unclear, or raises questions (e.g. drainage, overshadowing, traffic), the council may ask for Further Information. This pauses the decision clock until you submit the requested details. Once submitted, the planner has another 4 weeks to assess the updated proposal.
⚖️ Appeals to An Coimisiún Pleanála
If your application is appealed, it’s reviewed by the national planning appeals body. Appeals are supposed to be decided within 18 weeks, but due to backlogs and case complexity, some take more than 6 months. Only people who made submissions during the 5-week window (or the applicant) can make an appeal.
💬 Pro Tip: A Good Application Helps Things Along
One of the most common reasons for delays is simple: incomplete, unclear, or non-compliant applications. To avoid this:
Include all the required drawings, maps, and documents,
Make sure everything matches across forms and drawings,
Review the development plan and any local area plans to make sure your project aligns with the council’s vision for the area,
Consider getting professional help — a planning consultant or architect can help ensure nothing is missed.
A well-prepared submission is your best defence against costly delays.
🧭 Special Cases: When Different Timelines Apply
The timelines above apply to standard domestic planning applications — like extensions, outbuildings, or one-off houses. Other types of development may take longer or follow different processes:
Large housing schemes (“Large-scale Residential Development” or “LRDs”),
Protected structures or developments in Architectural Conservation Areas,
Public infrastructure projects,
Certain public projects such as buildings in the council’s own area, Garda Stations, and Courthouses.
In these cases, talk to your local authority or seek professional advice early.
