One-off house planning refused: the reasons and how to fix each

A refusal notice lists the reasons the council gave, and each one is a separate problem with its own fix. Some are practical (an entrance with poor visibility, a wastewater report that does not prove the site works), some are about the house (position, size, design) and some are about you (whether policy allows you to build in that area). Read each reason before deciding whether to reapply, appeal or look at a different site. This guide goes through the reasons that appear most often on rural one-off houses. For how the application works from the start, read planning permission for a one-off house.

First, read what you were actually given

Two documents matter: the decision notice and the planner’s report on the council’s online planning register. The notice gives the reasons in short, formal wording. The report usually says more: what the planner measured, which policy of the county development plan they applied, and what the roads engineer or environmental health officer said. Download both, and the reports from any other body the council asked, such as the roads section or the Environmental Protection Agency.

Also check you were refused and not told the application was invalid. An invalid application is returned before it is assessed, with the fee, because something required was missing. That is fixed by correcting it and lodging again; see planning application cost for what happens to the fee. Everything below is about a refusal.

Reason 1: traffic safety, the entrance and sightlines

What it says. Typically that the proposed entrance would be a traffic hazard because drivers cannot see far enough along the road in one or both directions, or that the extra traffic would be unsafe on that road.

What it means. The council’s roads engineer measures the clear view from the entrance, called the visibility splay or sightline, and compares it with the distance their standard requires for the road and its speed. The posted speed limit does not settle the distance. Ask the council which distance applies to your road rather than using figures from a neighbour’s permission.

What usually fixes it.

• A sightline survey by a competent engineer or surveyor, showing what can be achieved from the entrance, with measurements both ways.
• Moving the entrance along your road frontage to where the view is better.
• Setting back or lowering your own hedge, wall or bank, with the replanting the council will want to see.
• Agreement with a neighbour or the owner of the verge, in writing, if the sightline crosses land you do not own. Without a legal right to keep that land clear, the council can still refuse.

When it does not. If the frontage is short, the road bends or the view needs land you cannot get, the site may not work for a house. Check this before you buy a site: see buying a site for a self-build.

Reason 2: rural housing need (local need)

What it says. That you have not shown the social or economic need the county development plan requires for a house in that area, or that the area is one where one-off houses are limited.

What it means. The county development plan, following the national Sustainable Rural Housing Guidelines and National Policy Objective 28, sets who can build in which area. In places under strong urban influence the test is strict; elsewhere siting and design carry more weight. See rural housing and local need.

What usually fixes it. Not a new design. The options are:

• Better evidence of a link the plan already recognises, such as long residence, farming or other rural work, or caring for a relative, with the documents the council asks for.
• A different site in a village or settlement where the test does not apply.
• An appeal, if you believe the council read the plan or your evidence wrongly. The Commission decides the case afresh against the same policy, so be realistic about the odds.

Because this is the one reason a redesign cannot answer, get a planner’s view before paying for new drawings. A draft replacement rural housing statement has been discussed; a draft is not a grant of permission, so ask the council which policy applies to a new application.

Reason 3: wastewater and site suitability

What it says. That the site has not been shown to be suitable for an on-site wastewater system, or that the proposed system does not comply with the EPA Code of Practice, so there is a risk of pollution of groundwater or wells.

What it means. The 2021 EPA Code of Practice covers systems for up to 10 people. The site characterisation report must show enough soil above the water table and bedrock, a percolation result in range, the required distances to wells, streams and boundaries, and a system that suits the result. See will your site pass a wastewater assessment.

What usually fixes it.

• A new or corrected assessment by a registered site assessor, answering the exact point on the notice. Councils have refused where the assessment was missing, based on an old report, or did not meet the Code’s distances or tests.
• A different system, or a different position for the house, tank and percolation area, if the results allow it.
• A site layout drawn to scale to show the separation distances fit.

When it does not. If the soil fails or the site is too small for the separation distances, a new report will give the same answer. Ask the assessor before paying for design work.

Reason 4: design, siting and visual impact

What it says. That the house would be prominent in the landscape, out of character with the area, too large or badly sited, or ignores the county’s rural design guidance.

What it means. Many county plans include a rural design guide and say what suits the landscape: a house that sits into a slope, uses an existing hedgerow, is modest in height and is not visible on a ridge. The test is generally whether the house blends in once the site works are counted, not whether it is invisible.

What usually fixes it.

• Moving the house to a less visible part of the site, or lower, or behind existing planting.
• A smaller or lower design, simpler massing, and materials the design guide accepts.
• Keeping existing boundaries rather than removing them to make way for an entrance or sightline. If the sightline needs removing a long hedge, that may trigger a different refusal.
• Photomontages or sections that show the height against the landscape.

Ask for a pre-planning meeting before redrawing, and take the planner’s comments on the revised design in writing.

Reason 5: ribbon development and the number of houses on the road

What it says. That the house would add to a line of existing houses along a road, or exceed the number the plan allows on that stretch.

What it means. Ribbon development is a line of houses strung along a rural road. National policy asks councils to avoid it, and each county plan sets its own measure. Meath and Wexford, for example, both treat five or more houses on one side of a 250 metre length of road frontage as ribbon development; see the county pages for Meath and Wexford. Your county may measure it differently.

What usually fixes it. Less than people hope. The count is of existing houses along the frontage, so moving the house along the same road rarely changes it. A site on a different road may count differently. Ask the planner how your county plan measures it on your road, and which exceptions it allows, before paying for a new design.

Reason 6: flood risk

What it says. That the site, or its access, is at risk of flooding, and the application did not show otherwise.

What it means. Councils look at flood maps and the national guidelines on planning and flood risk, which advise avoiding development in flood-prone areas. Check the site on Floodinfo.ie, which shows the Office of Public Works flood information, including past events and modelled flood extent.

What usually fixes it. A flood risk assessment by an engineer, which may show the house sits above the flood level, or that part of the site can be used. If the house itself is in the flood extent, a redesign seldom helps; ask about a different part of the site. Also check the access road, since a house the council cannot reach in a flood may still draw a refusal.

Reapply or appeal?

Use the reasons to decide.

If the reasons are mostly…	Usually consider	Why
Sightlines, wastewater evidence, design or siting	Reapplying with the specific points answered	You can change the evidence or the design, which the Commission would otherwise have to judge as it stands
Local need or the area’s policy	An appeal only if you think the policy was misread, otherwise a different site	A new design does not change who the policy allows to build
A single point you think the council got wrong	Appealing	The Commission decides the case afresh and can grant permission
Several reasons that overlap	A planner’s view first	Fixing three of four reasons still leaves a refusal

The main practical points:

• Time limit. An appeal must arrive within four weeks beginning on the date of the council’s decision. See planning objections and appeals for how to count it and how the process runs.
• Fee. The October 2026 appeal fee for an applicant with no retention is €220. A new application pays the council’s application fee again; see planning application cost and ask the council whether any reduction applies to a resubmission, rather than assuming one does.
• You cannot do both at once. While an appeal is pending, an application for the same or a similar development cannot be made, and the council must return one that is lodged (section 37(5)). Choose before the four weeks run out; you can withdraw an appeal later, but you will have paid the fee.
• Time. A new application restarts the council’s decision period; an appeal adds the Commission’s time on top. Check the Commission’s current decision-time objective before you plan around it.
• The whole case is reconsidered. An appeal can lead to a better outcome or different conditions. Weigh that before relying on it.
• Cost of professionals. A new report or drawings costs money; get quotes before choosing.

What not to do

• Do not start building. Without a grant of permission, work on a new house is unauthorised development.
• Do not lodge the same application again. The council compares it with the earlier one. Answer each reason in writing and point to where the new documents do so.
• Do not guess the reason. If the notice is unclear, ask the planner what would address it.
• Do not ignore the contract if you are buying. If the sale is conditional on permission, check the deadline and what the contract says about refusal and your deposit. See buying a site for a self-build.

Why site owners still need insurance

If you own the site, you are responsible for what happens on it even while the application is being decided. Public liability for a site owner and the cover you will need once work starts are separate questions. See self-build insurance in Ireland, and check which covers your project needs before you commit to a start date.

What to do next

1. Download the decision notice and the planner’s report from the council’s register.
2. List each reason and mark it: fixable with evidence, fixable with design, or a policy matter.
3. Note the date of the decision and count four weeks for any appeal.
4. Ask the planner at a pre-planning meeting what would answer each reason, and get the reply in writing.
5. Get quotes for any new report or drawings before choosing between reapplying and appealing.
6. Check your contract and lender timeline against the new decision date.
