Planning is the longest pole in an Irish self-build and the one least affected by how you build. Understanding the sequence is what stops you paying for work in the wrong order.
Before you buy the site
- Rural housing policy. Many county development plans restrict one-off rural housing to applicants with a demonstrated local need. Read the local plan for that county before you fall in love with a field.
- Access and sightlines. A site whose entrance cannot achieve the required sightlines is a refusal waiting to happen, and sightlines often need land you do not own.
- Wastewater. A site assessment and percolation test determine whether and what kind of treatment system is possible. On some sites the answer is no.
- Services. Distance to ESB and to a water main, and whether a well is viable.
- Designations and flood risk. Check before, not after.
The sequence
- Pre-planning consultation with the local authority — free, and worth more than any other hour you will spend
- Site suitability assessment and percolation test
- Design, site layout and drawings
- Statutory notices: site notice and newspaper notice, both with strict timing rules
- Lodge the application
- Validation, then the assessment period; a request for further information is common and resets the clock
- Decision, then the third-party appeal window before it becomes final
- Discharge any pre-commencement conditions and pay development contributions
- Appoint the PSDP, submit the commencement notice and, where applicable, the BCAR certificates
- Start on site

Where a factory frame fits
Manufacturing runs in parallel with your foundation, not with your planning. Once permission is final and the foundation programme is set, the frame is booked to arrive when the slab has cured. That is the only part of the schedule a kit compresses — but it compresses it a lot.
Frequently asked questions
How long does planning permission take in Ireland?
Eight weeks is the statutory minimum for a decision, but a one-off rural application realistically takes six to eighteen months from first site assessment to being able to start on site.
Do I need to own the site before applying?
No, but you need the landowner’s written consent to apply, and you need to be able to demonstrate control of any land needed for access and sightlines.
