Do I Need Planning Permission?
Not all building works require planning permission. Certain developments are classified as exempted development under Irish planning legislation, provided they comply with the relevant conditions and limitations.
Common planning exemptions include:
House Extensions: Rear extensions of up to 40m² may be exempt, subject to restrictions on height, previous extensions, boundaries and remaining garden space. Additional limits apply to extensions above ground-floor level.
Garages and Sheds: Domestic outbuildings of up to 25m² may be exempt, subject to height, location and usage restrictions.
Garage Conversions: Converting an attached garage for domestic use may be exempt, depending on the nature of the works.
Front Porches: Porches of up to 2m² may be exempt, subject to height and setback requirements.
Walls and Fences: Certain boundary walls, fences and gates may be exempt, depending on their height and location.
Solar Panels: Rooftop solar panels on houses are generally exempt, subject to applicable conditions and restrictions.
When Is Planning Permission Required?
Planning exemptions may not apply where a property is a Protected Structure, is located within an Architectural Conservation Area, or is subject to planning conditions restricting exempted development.
Previous extensions, alterations and site-specific circumstances can also affect whether works qualify for an exemption.
Importantly, meeting the maximum permitted floor area does not automatically mean a development is exempt from planning permission.
