Understanding Irish Garden Shed Regulations
Are you considering adding a garden shed or garage to your Irish property? Understanding the planning permission requirements is essential before you begin your project. This comprehensive guide explains exactly what size garden shed you can build without planning permission in Ireland, based on current regulations from the Department of Housing, Local Government and Heritage¹.
The 25 Square Metre Rule Explained
According to the Planning and Development Regulations², in Ireland, you can construct a garden shed or garage without planning permission, provided it meets specific size requirements. The primary regulation states that structures must not exceed 25 square metres in total floor area.
However, there are several important considerations:
- Combined Structure Limitations
- The 25 square metre allowance includes ALL existing structures
- Any existing sheds, garages, or similar buildings count towards your total
- You must calculate the combined area of all outdoor structures
- Property Space Requirements
- Your property must maintain at least 25 square metres of open space
- This applies to both rear and side areas of your house
- The rule ensures adequate outdoor living space remains
Additional Planning Considerations
Location Restrictions
Whilst the 25 square metre rule applies nationally, local authorities may have additional requirements. The Local Government Planning and Development Act³ emphasises checking with your local planning office before beginning construction.
Property Type Considerations
Different rules may apply for:
- Listed buildings
- Properties in conservation areas
- Homes in designated areas of outstanding natural beauty
Professional Recommendations
Before starting your garden shed project:
- Measure your existing outdoor structures
- Calculate remaining allowance within the 25 square metre limit
- Consider consulting a planning professional
- Document your measurements and plans
