Do you need planning permission for a pergola or awning in Ireland? (2026)
Short answer: often not, if the structure is for your own house and stays within the exempted development rules. But it depends on the type of structure, where it goes and your property. The rules changed on 27 July 2026, so older guides may be out of date. This guide is general information, not legal advice. Your local planning authority has the final say.
The short answer
A retractable awning or a freestanding pergola at the back of a house is often exempted development. That means no planning application, as long as it meets the conditions below.
A structure in front of the house, above the size or height limits, or on a protected structure or in an architectural conservation area needs a closer look.
If you are not sure, ask your council before you order.
What changed on 27 July 2026
New exempted development regulations for homes came into effect on 27 July 2026 (S.I. No. 338/2026). Two changes matter for outdoor structures:
Garden structures such as sheds, stores, garages and greenhouses: the maximum total floor area within the grounds of a house rose from 25 m² to 30 m².
Extensions to a house: the total floor area limit rose from 40 m² to 45 m².
Conditions that usually apply to a garden structure
The exemption for structures in the grounds of a house (Class 3, Schedule 2, Planning and Development Regulations 2001) names tents, awnings and shade structures alongside sheds and greenhouses. The main conditions are:
It must not be in front of the front wall of the house.
Height: no more than 4 m with a tiled or slated pitched roof, otherwise 3 m.
Total floor area of all such structures in the grounds: up to 30 m², counting any existing sheds or stores.
At least 25 m² of private open space must remain at the back or side of the house.
It must not be lived in, used to keep animals such as pigs, poultry or horses, or used for anything beyond purposes incidental to enjoying the house.
A pergola fixed to the house wall may be treated as an extension instead. Extensions have their own conditions: for example, they cannot be higher than the house and at least 25 m² of private open space must remain at the rear. Whether your pergola counts as an extension or as a garden structure is for your planning authority to decide.
When you may need planning permission
Your home is a protected structure or is in an architectural conservation area.
Your original planning permission, for example in a housing estate, has a condition that removes exemptions.
The structure is in front of the house, or above the height or size limits.
It is for a pub, restaurant, café, hotel or other commercial premises. The exemptions for houses do not apply, so check with your planning authority before you order. Fire safety and any licence for outdoor areas may also matter.
You live in an apartment or rent your home. This is not a planning matter, but your landlord or management company may need to agree.
How to be sure
Check the conditions of your original planning permission, if there is one.
Ask your local planning authority whether your plan is exempted development. You can request a formal written declaration (a Section 5 declaration).
Have your measurements ready: width, projection, height and a photo of the space. We can confirm the exact dimensions of your pergola or awning for your enquiry.

FAQ
Do I need planning permission for a retractable awning?
Often not for the back of a house, if it meets the exemption conditions above. A protected structure, a conservation area, a planning condition or a commercial property can change that, so ask your council if you are unsure.
Do I need planning permission for a pergola in my garden?
A freestanding pergola within the limits above is often exempt. A pergola fixed to the house may be treated as an extension. Your planning authority decides.
Do the 2026 changes apply to a pub or restaurant terrace?
The new exemptions are for houses. Commercial premises follow different rules, so check before you order.
