Do You Need Planning Permission?

If you’re building a new home, extending an existing one, or making significant changes to your property, planning permission may be required. While some smaller works can be exempt, it’s important to confirm this before construction begins.

At J Floyd Engineering Ltd., we guide homeowners through the planning process — helping you understand what’s required, how your proposal aligns with the local Development Plan, and what’s needed to submit a strong application.

​

Types of Planning Permission

There are three main types of planning permission in Ireland:

Permission (Full Permission)
The most common route, used when you’re ready to submit a complete and fully detailed proposal.

Outline Permission
Useful if you want confirmation that a development is acceptable in principle — for example, building on a site or proposing a substantial extension. This stage requires only basic information on layout and location.
If granted, it must be followed by a full application for Permission Consequent on Outline Permission.

Permission Consequent on Outline Permission
The second stage of the process, where detailed drawings and technical information are submitted following outline approval.

​

Important Legal Note

Carrying out works that require planning permission without approval is a criminal offence and can result in significant penalties.

If work has already been carried out, it may be possible to apply for retention permission. However, approval is not guaranteed, and refusal can require the works to be altered or removed. Early professional advice is essential.
