Are you planning a new build, home extension, or renovation in Ireland but unsure about the costs of planning permission? Securing planning permission is a crucial step in turning your project into reality, and understanding the expenses involved can help you plan your budget more effectively.
Planning permission ensures your development aligns with local regulations and environmental standards, preventing potential legal issues down the line. Whether you're building your dream home, adding an extra room, or developing a commercial property, knowing the associated costs is essential for a smooth process.
In this blog, we'll explore how much does it cost to get planning permission in Ireland, the factors affecting the fees, and provide tips to navigate the process efficiently.
What is Planning Permission in Ireland?
Planning permission in Ireland is a legal requirement for constructing new buildings, making significant alterations to existing structures, or changing land use. It ensures that developments comply with local planning policies, environmental regulations, and safety standards.
The process involves submitting detailed plans to the local authority, who will assess the proposal's impact on the surrounding environment, infrastructure, and community.
Without proper approval, you risk penalties, enforcement actions, or difficulties when selling the property. Whether you're building a home or expanding a business, securing planning permission is essential for a smooth, legally compliant development process.
How Much Does It Cost to Apply for Planning Permission?
The cost of applying for planning permission in Ireland varies depending on the type of development you’re planning.
For a new house application, the current fee is €65. If you're applying for a house extension or converting a garage into part of your home, the fee is €34.

These are the standard fees set by local authorities, but additional costs can arise if you need professional drawings, site surveys, or further documentation to support your application.
Always check with your local council for the most up-to-date fee structure before submitting your application.
When Do I Need Planning Permission?
You will need planning permission if you are building a new house in Ireland. It may also be required for extensions, renovations, or significant changes to existing structures.
However, some minor projects, like small extensions or conservatories, can fall under exempted development and may not require permission. Always check with your local authority before starting any work.
Planning permission is also necessary if you intend to change how you use land or buildings. For instance, converting part of your home into a creche or using your property for short-term rentals might require approval.
Some exceptions exist, such as converting certain vacant commercial properties, including pubs, into residential units under the Planning and Development Regulations 2001 to 2021.
Modular homes, often called rapid-build homes, may also need planning permission, depending on their size, location, and purpose. While the Irish Government can bypass permission for emergency housing, environmental considerations remain essential when selecting sites.
To avoid costly mistakes, consult your local authority for guidance. They can confirm if your project needs planning permission and advise whether it aligns with the area's development plan.
What Are the Types of Planning Permission?
In Ireland, there are two main types of planning permission: Permission (Full Permission) and Outline Permission.
Each serves a different purpose depending on the stage of your project.
Permission (Full Permission)
This is the most common type of planning permission. It grants full approval for your project, allowing construction to begin, provided you meet the conditions set by the local authority.
These conditions might involve minor changes to your original proposal. Full planning permission typically lasts for 5 years, giving you enough time to complete the project.
Outline Permission

Outline permission determines if the local authority agrees in principle to your proposed development, such as a new house or large extension.
This application requires fewer details than a full application but must include enough information for the authority to assess the site layout and overall development impact.
If outline permission is granted, it usually lasts for 3 years, and you’ll need to submit detailed drawings for consequent permission before starting any construction.
What Happens If I Need Planning Permission but Don’t Apply for It or Get It?
Carrying out work without the required planning permission is considered an offence in Ireland and can result in serious consequences. This includes big fines and even possible imprisonment in severe cases.
Local authorities have the power to issue enforcement notices, requiring you to cease construction immediately. However, if the lack of permission was a genuine mistake, you can apply for retention planning permission to legalise the unauthorised development.
It's important to note that this does not guarantee approval. If the local authority refuses retention permission, you will be required to demolish the unauthorised structure and restore the site to its original condition.
To avoid such complications, always check with your local authority before starting any construction project.
Conclusion
Understanding how much does it cost to get planning permission in Ireland is crucial for budgeting any construction project, whether it's a new build, extension, or renovation.
Costs vary depending on the type of development, with standard fees ranging from €34 for house extensions to €65 for new house applications. Beyond application fees, you should also consider expenses for architectural plans, site surveys, and potential revisions requested by the local authority. Ensuring you follow the correct process can save you from costly fines or delays.
