When is Planning Permission Required?

Generally, you WILL need planning permission if:

• The dormer window is at the front or side of the house.
• The dormer significantly alters the roof profile.
• The structure overlooks neighboring properties, raising privacy concerns.
• The house is a protected structure or in an Architectural Conservation Area (ACA).
• The extension results in a significant increase in habitable space.

Consequences of Building Without Planning Permission

If you build a dormer without the required planning permission, you risk:

• Enforcement action from the local council.
• Fines or legal penalties.
• Being forced to remove the dormer at your own cost.
• Difficulties when selling your property (compliance certificates may be required).

How to Apply for Planning Permission

The process involves several steps:

1. Consult a Professional: Work with a design-build firm like BAYT, an architect, or a planning consultant.
2. Prepare the Planning Application: Submit site location plans, existing and proposed drawings, and design statements.
3. Submit to Dublin City Council: The application process typically takes 8 weeks, including a public consultation period.
4. Address Any Objections: Adjustments may be needed if there are concerns from neighbors.
5. Receive Your Planning Decision: Approved planning permission is valid for 5 years.
