Frequently asked questions
How much does planning permission cost in Mayo?
The statutory application fee is the same across Ireland: 65 euro for a new house and 34 euro for a domestic extension or garage. Retention permission costs three times the standard fee. On top of that, most applicants pay a professional (architect, engineer, or planning consultant) for drawings and the application itself - typically 1,500 to 5,000 euro depending on the project.
How long does planning permission take in Mayo?
Mayo County Council must decide within 8 weeks of receiving a valid application. There is a 5-week period for public observations, and a 4-week appeal window after the decision. A request for further information restarts the clock, so 3 to 6 months end to end is common.
Do I need planning permission for an extension in Mayo?
Not always. Rear extensions up to 45 square metres are generally exempt from planning permission, subject to conditions on height, remaining garden space, and previous extensions. The same national exemption rules apply in Mayo as everywhere in Ireland.
How long does planning permission last in Mayo?
A grant of planning permission normally lasts 5 years from the date of the decision. If you have not substantially completed the work in that time you must apply again or seek an extension of duration.
Where do I submit a planning application in Mayo?
Applications go to Mayo County Council, online through eplanning.ie or on paper at the council offices. You must also publish a newspaper notice and erect a site notice before applying.
