Building a house in County Kilkenny: the urban influence map, the five-year local test and the €7,000 charge

Who decides, and how to apply

Kilkenny County Council decides applications for the county. Its planning applications pages explain how to apply and let you search applications already made, which is a quick way to see how the council has treated sites near yours. The rural housing rules are in chapter 7 of the Kilkenny City and County Development Plan 2021-2027 (sections 7.8.3 to 7.8.5). The council has varied the plan several times since adoption, so check the current text and the variations before you buy a site.

Read how a one-off house application works first. The council also publishes a Rural Design Guide, produced in 2008, and the plan advises anyone building in the countryside to read it early for advice on site choice, local design and landscaping.

Two kinds of countryside

Under the National Planning Framework, a county must treat rural areas under urban influence differently from the rest. Kilkenny does so on a map (Figure 7.1 of the plan). Areas under urban influence are the countryside close to Kilkenny City, the Waterford area, the district towns of Callan, Castlecomer, Graiguenamanagh and Thomastown, and New Ross and Carrick-on-Suir. The plan describes them by high commuting, high population growth and ready road access to the larger towns.

• Inside an area under urban influence, the council permits a single house for a person with a demonstrable economic or social need to live in that local rural area, as described below.
• In the other rural areas, housing restrictions do not apply, and an application is judged on normal siting, design and environmental criteria, including road safety, wastewater and the visual setting.

The need test does not apply on zoned land or inside a defined settlement, where the council wants non-rural housing to go. The plan says it prefers to direct people with no rural ties to towns and villages.

Economic need

The economic route covers someone employed full-time in a rural-based activity in the area where they want to build, such as farming, horticulture, forestry or bloodstock. It also covers someone whose work is intrinsically linked to the area, such as a teacher in a rural school, or who has a functional need to live permanently close to their place of work. In every case you must never have owned a house in a rural area. Evidence is usually the farm holding, employment letters and tax records, so gather them before you apply.

Social need

The social route covers a person born in the local rural area, or who has lived a substantial part of their life there (the plan sets a minimum of 5 years), who has never owned a rural house and wants to build a first home close to the original family home. Someone born in the area without the 5 years must show strong family and social connections instead.

Returning emigrants can qualify too. They must not own a house in the local area, must have lived in the local rural area for a substantial period (5 years) before leaving, and want to return to live near other family members. For general advice on evidence, see rural housing and local need.

The “local area” is roughly a 10 km radius from the site, leaving out defined urban areas. Beyond that distance, the council considers a case on its merits if you can show significant ties, such as close family or long-established land ownership.

Occupancy, ribbon development and replacements

Every permission in an area under urban influence carries an occupancy condition. You or a member of your immediate family must live in the house as a permanent residence for 7 years from first occupation. In areas where one-off houses have built up around the edge of towns, the council may also seek a sterilisation agreement under section 47 of the Planning Act, which restricts further building on land you own.

The plan defines ribbon development as five or more houses on one side of a 250 metre length of road. Four houses on one side already make an extra house likely to create a ribbon. The council can allow well-spaced infill to complete a settlement pattern, but not where it leads to more gap sites or joins separate ribbons.

For replacing a house, you must show the old structure was last used as a dwelling and was habitable, so the rural housing policy does not apply. If it was not habitable, a proposal that sensitively restores a vernacular or traditional building is also outside the policy. Where the old house cannot feasibly be reused, the replacement should fit the site and follow good rural design.

The development charge

Kilkenny County Council’s Development Contribution Scheme 2026-2030 sets different rates for a house where the rural housing policy applies. It charges €26 per square metre for a house of up to 125 square metres, €35 for 126 to 200, €50 for 201 to 275, and €75 above that. The scheme says the band rate applies to the full floor area, so a 200 square metre rural house pays 200 × €35 = €7,000. A house just over 200 square metres moves to the €50 band, so the whole area costs more. Check your design against the band before you finalise the plans.

The council may update the rates each year using the CSO wholesale price index for building and construction, so the amount on your permission can be higher than the scheme’s figure. A garage or shed of up to 25 square metres is not charged, and extensions up to a cumulative 40 square metres are exempt. Retention applications pay 1.5 times the rate with no exemptions.

The scheme also says the council intends to bring forward a waiver for first-time buyers of houses up to 200 square metres. Ask the council whether it is in force before you rely on it. The national waiver covered only homes started on site between 25 April 2023 and 31 December 2024, so a house starting now cannot qualify for that one. See the waiver guide.

To see how Kilkenny’s charge compares, the development contributions table compares the charge for a 200 square metre house across all 31 councils.

Wastewater and site suitability

Almost every rural house treats its own wastewater, and a site that fails the assessment cannot be built on whatever your local connection. Read site suitability assessments and wastewater treatment systems before you pay for the test.
