How to object to a planning application in Ireland — five weeks, €20, and 348 open windows today

On 12 September 2026, 348 applications across the seven Greater Dublin Area councils we index were inside their five-week observation window, 81 of them in Dún Laoghaire-Rathdown. The councils received 11,409 applications in the previous 12 months. Every one was open to comment from anyone, a neighbour, a residents' association, a rival business, a person on the other side of the country, for €20 and within five weeks. Councils call the comment a submission or an observation; the Planning and Development Act 2000 treats the two words as the same thing. The mechanics are simple. The stakes changed with the Planning and Development Act 2024: the €20 observation is now the only door into an appeal, and for most people the only door into the courts.

Does the five weeks start when the notice goes up?

No. Article 29 of the Planning and Development Regulations 2001 gives five weeks beginning on the day the council received the application. That date is printed on the register entry and usually on the site notice. Site notices must be erected within the two weeks before lodging, so a notice can be up for nearly two weeks before the clock starts, and the clock does not wait for you.

Five weeks means five weeks, weekends and bank holidays included. If the last day falls on a day the council office is closed, the Regulations roll it to the next working day. Do not rely on that. A late submission is returned with the fee. The council cannot consider it, and you lose everything below.

What the €20 buys

The fee under Schedule 9 of the 2001 Regulations is the same for a two-line email and a forty-page report. It buys four things. The council must consider the submission before deciding, and the planner's report will address it. You are notified of the decision in writing, with reasons and conditions. You may appeal the decision to An Coimisiún Pleanála (formerly An Bord Pleanála) within four weeks under s.37 of the 2000 Act; a person who made no valid submission cannot, save an adjoining owner who obtains leave under s.37(6).

The fourth is the one that changed. Section 286 of the 2024 Act gives sufficient interest to seek judicial review to a person who made "submissions of a material nature to the decision maker, in the appropriate form". That is the Oireachtas Library & Research Service's summary of 18 December 2025. It applies whether or not you are directly affected. Without a submission, an ordinary neighbour must show they are materially affected, and an unincorporated residents' association has no standing unless it meets the Act's rules on constitution and voting. Missing the window does not cost you a comment. It costs you every remedy after it.

Can I object if the application was invalidated and lodged again?

You must object again. This is the trap we see most in the register. Of the 2,539 applications declared invalid across the seven councils in the 12 months to 12 September 2026, 1,098 came back at the same address within 90 days. The re-lodged application has a new reference, a new receipt date, a new five-week window and a new €20 fee. An observation on the invalid file carries nothing across. If you watched a site notice come down in May, check the register in June.

What to write

A submission is assessed on planning grounds. The planner is asking whether the proposal accords with the development plan and with proper planning and sustainable development, and your submission is most useful when it answers that question. Quote the zoning objective for the site and any policy the proposal offends: building height, plot ratio, a protected view, a local area plan. Set out residential amenity with measurements: overlooking with distances to your windows, loss of daylight, overbearing bulk relative to the terrace. Give traffic points specifics, a junction sightline or a school opening time. Cite drainage, flooding, trees and heritage from the council's own maps. And cite precedent: a nearby application refused for the same reasons. The register is public and our search finds decisions by keyword.

Some points carry no weight and can weaken the rest. The effect on property values. The character of the applicant. Private rights such as a boundary, a right of way or a covenant, which survive a permission regardless under s.34(13). Construction nuisance, which is managed by condition.

Say what you want: refusal, or the specific changes that would make the scheme acceptable. A planner can condition a grant, and a submission that offers the condition is easy to act on. Keep it factual and short. Attach photographs and a marked-up plan.

Our reading: the observations that change decisions are the ones the planner can lift straight into the report. One page of development-plan objectives and measured distances beats ten pages of objection.

How to lodge it

Every council accepts a written submission by post or at the counter, and most now accept it online; Dún Laoghaire-Rathdown and Fingal through their planning portals. Include the application reference, your name and address, the €20 fee and a request to be notified of the decision. Keep the acknowledgement. It is the document the Commission asks for with an appeal, and the proof of "submissions in the appropriate form" if you ever go to court.

Our observation pages assemble the reference, the deadline, the fee and the council's address for any application we index, with the planner's likely headings. The writing is yours.

After you submit

The council decides within eight weeks of receiving the application, or four weeks after any further-information reply. If the applicant's reply is "significant", new notices go up and you are written to with a further two-week window; there is no second fee. When the decision issues you have four weeks to appeal. The appeals guide covers the fee, the form and the odds.

Frequently asked questions

How long do I have to object to a planning application in Ireland?

Five weeks from the date the council received the application (article 29 of the 2001 Regulations). The receipt date is on the register entry and on the site notice.

How much does it cost to object to planning permission?

€20, paid to the council with the submission. There is no further fee if significant further information is later re-advertised. An appeal to An Coimisiún Pleanála costs €220.

Can I object anonymously?

No. A submission must carry your name and address, and it is placed on the public file.

What if I miss the five-week deadline?

The council returns the submission unread. You cannot appeal the decision, unless you own or occupy adjoining land and obtain leave under s.37(6), and under the 2024 Act you will generally not have standing to seek judicial review.

Do I have to be a neighbour to make an observation?

No. Any person or body may make a submission on any application, for the same fee.
