Planning Permission Advice in Ireland: Before You Apply

Whether you are planning an extension, an alteration or a conversion, planning problems are easier and cheaper to handle when the scope and site constraints are understood from the start.

Step 1

Find out what decision you actually need

Not every home improvement requires a full application. Some works may fall within exempted development provisions, while others require permission. Restrictions can arise from protected status, conservation areas, conditions in earlier permissions and the specific site.

Step 2

Review the planning history

Look at prior applications and decisions for the property and nearby sites. Identify any relevant conditions, boundaries or previous extensions. The local authority planning portal is a useful starting point.

Step 3

Prepare a project brief before drawings

Set out what you hope to build, why the existing building does not meet your needs, the likely layout and your budget range. Include site photos and sketches. A professional can then advise on feasibility, supporting documents and suitable next steps.

Step 4

If your application is refused or delayed

Identify the precise issues raised by the planning authority before revising plans. A response may require a change to the design, additional information or specialist advice. Deadlines and procedural rules matter; never assume a general guide covers your case.

Step 5

Check professional credentials and scope

HomeUpgrade may be able to introduce a planning or design professional. A registered architect is used where the project and client require that role. All fees, statutory responsibilities and deliverables should be agreed directly and in writing.

Your checklist before starting

  • Describe your project and collect existing documents.
  • Check the local authority planning history and development plan.
  • Have the proposal reviewed for possible exemptions or permission requirements.
  • Obtain an agreed scope and fee for drawings or the application.
  • Review permission conditions and building-control obligations before starting work.

Common questions

Can HomeUpgrade tell me whether my project is exempt?

We can help you find the right next step, but a site-specific statutory determination or suitably qualified professional assessment may be needed.

Can a registered architect help?

Yes, where available, a registered architect can be introduced following your permission and agreement about the proposed service.

What if I already have plans?

You can describe the plans and the issue in our form. We will review the enquiry and discuss whether another professional assessment would help.
