What a development plan controls
Every council has one. It is written for a set number of years and changed in steps called variations. It covers four things that matter most to a homeowner.
Every piece of land has a zoning, such as residential, town centre or agriculture. The zoning says what can be built there. An extension is usually fine in a residential zone. A new house on land zoned for agriculture usually is not, unless a rural housing rule allows it.
Outside towns and villages, the plan decides who can build a one-off house. Councils often ask for local ties, such as family land or years of living in the area, and may attach an occupancy condition.
The plan uses flood zones. New homes in Flood Zone A or B can face a justification test and a flood risk assessment. The official flood maps are on floodinfo.ie.
The plan lists protected structures and architectural conservation areas. If your home is in one, works that are normally exempt may need permission. You can ask the council for a declaration under section 57.

Building a house in the countryside
Who can build a one-off rural house, and the conditions that come with it.
Louth has two rural policy zones, both under strong urban influence. Zone 1 also has significant landscape value (including Carlingford Lough and Mountains and the Brú na Bóinne area). In Zone 1 you qualify if you are in full-time agriculture, a son or daughter of a qualifying landowner building a first home, run a business that depends on the location, have exceptional health reasons, provide care to an isolated rural resident, or lost a home through separation or repossession after 10 years' residence. A qualifying landowner owns at least 1.5 hectares and has owned it for at least 15 years, and no more than three houses are allowed on the holding.

Social ties normally mean living in the rural area of Louth for at least 18 years before applying. You must show a rural housing need and not own or have sold a home in the county. The site is not normally more than 6 km from the qualifying family home.

There is a presumption against a one-off house in Zone 1 where there is an alternative site on family land in Zone 2. The council restricts building on land with a history of speculative site sales.

How it affects your project
The plan matters most when a project needs planning permission. Many small jobs are exempt, so check that first.
Many small extensions are exempt, so the plan only counts if you need permission, or your home is protected, or an earlier permission has conditions. When permission is needed, the council checks the design against the plan, for example overlooking, daylight and the garden left. Read the extension guide.
Small sheds are often exempt. A garden room used as a separate home, or a large one close to a boundary, can need permission, and then the plan's rules on extra accommodation apply. Read the shed guide.
A new house needs land where the zoning allows it. In the countryside, the rural housing rules decide who can build. Flood zones, access and wastewater also count. See the Louth rural housing rules. Read the new house guide.
Where to read the official plan and map
Always check the council's own copy. Plans are varied from time to time, and the zoning map is the legal record of how your land is zoned.

Common questions about the Louth development plan
What is the Louth development plan?
The Louth County Development Plan 2021-2027 (as varied) is the main planning policy document for Louth County Council. It covers 2021 to 2027 and sets the zoning of land and the local rules the council uses when it decides planning applications.
Where can I see the zoning for my land in Louth?
Zoning maps are part of the plan. Open the plan on the Louth County Council website, or use the national viewer at myplan.ie, which shows zoning for councils that have supplied it. Plans can be varied between full reviews, so check the council's own copy for the latest.
Does the Louth development plan matter if my project is exempt?
If your extension or shed is exempt development, you do not need planning permission, so the council does not assess it against the plan. The plan still matters if your home is a protected structure or in a conservation area, or if an earlier permission has conditions. Our free checker screens your project.
Can I build a house on family land in Louth?
It depends on the rural housing rules in the plan and on exactly where the site is. Councils usually ask for proof of local ties and attach an occupancy condition. The summaries on this page show what the Louth plan says, and the council's pre-planning meeting is the best way to test your case.
