Mayo County Council covers a large county stretching from Castlebar, Ballina and Westport to Achill Island, the Erris peninsula, Clew Bay and Ireland West Airport Knock. With extensive Gaeltacht areas, a long Atlantic coastline and a strong tourism economy, Mayo raises a wide range of planning issues.
Ireland Planning advises homeowners, farmers, landowners, businesses and developers on planning permission in the Mayo County Council area. Our work is led by Patrick O’Reilly, a chartered planner and a Full Corporate Member of the Irish Planning Institute (MIPI). We review the planning history, the Mayo County Development Plan and any site constraints before you commit to drawings or a purchase.
Planning permission in Mayo: local context
Mayo's Gaeltacht areas, including Erris (Iorras), Achill and Tourmakeady, have language protection policies that can affect new housing through language enurement conditions or linguistic impact statements.
Clew Bay, Achill, Croagh Patrick, the Nephin Beg range and the Erris coast are sensitive and often protected landscapes, many with Special Area of Conservation or Special Protection Area designations. Siting, design, wastewater treatment and coastal erosion are frequent issues, especially for one-off houses and tourism accommodation along the Wild Atlantic Way and the Great Western Greenway.
Castlebar, Ballina and Westport are the main towns, with steady demand for housing, town-centre regeneration and commercial development. Westport's town centre is an Architectural Conservation Area, so design quality matters for shopfronts and extensions.
Key planning considerations in Mayo
These are the issues that most often decide applications to Mayo County Council:
- Erris, Achill and Tourmakeady Gaeltacht policies
- Clew Bay, Achill and Atlantic coastal landscapes
- Wild Atlantic Way and Greenway tourism development
- Rural housing and wastewater treatment
- Westport ACA and town-centre regeneration
- Development near Ireland West Airport Knock

Planning refusals and appeals to An Coimisiún Pleanála
If Mayo County Council has refused permission or attached conditions that make a project unworkable, the options include an appeal to An Coimisiún Pleanála, a revised application that addresses the reasons for refusal, or a further information strategy. We review the planner’s report, the reasons for refusal and the relevant policies before recommending a route. See our planning refusals and appeals service.
Frequently asked questions about planning permission in Mayo
Can I build a holiday home in Mayo?
Mayo County Council generally prioritises permanent homes for people with a local need in rural areas, and some coastal areas restrict holiday homes. We review the policy for your specific area and whether a tourism or permanent-home case is stronger.
Is a linguistic impact statement needed for a house on Achill?
It can be, as parts of Achill are in the Gaeltacht. We check the language policy that applies and prepare the supporting information.
How long does Mayo County Council take to decide a planning application?
Mayo County Council must generally decide a valid planning application within eight weeks of receiving it. If the council requests further information, the decision is usually due within four weeks of that information being received. Invalid applications are returned, so a complete, well-prepared submission saves time.
Can I appeal a decision made by Mayo County Council?
Yes. Applicants, and third parties who made a valid submission on the application, can generally appeal a decision by Mayo County Council to An Coimisiún Pleanála (formerly An Bord Pleanála) within four weeks of the decision date. The deadline is strict, so get advice as soon as the decision issues.
