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.
Cavan sorts the countryside into three types. Around Cavan Town and in the south east (strong urban influence), new rural houses are limited to landowners and their immediate family with a social or economic need to live there. For this purpose the plan defines a landowner as someone with at least 10 hectares, and others are looked at case by case. In stronger rural areas, rural-generated social or economic need is facilitated. In structurally weak areas, the aim is to accept demand for permanent homes, subject to siting, design and environmental checks.

The design rules the council uses when it looks at work on an existing home.
The council views extensions positively but they must be subordinate in scale, suit the area, and not harm neighbours. They must not create new overlooking of a neighbour's private area, must not significantly cut daylight or sunlight to neighbours, and side extensions should keep side access to the rear for refuse collection and utilities. Flat roof and contemporary designs are judged on their merits.

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. See the Cavan extension rules. 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 Cavan 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.
Check your Cavan site before you apply
The pre-planning report covers zoning, protected structures, ground conditions and every application near your address, with the decisions.
Common questions about the Cavan development plan
What is the Cavan development plan?
The Cavan County Development Plan 2022-2028, including a Local Area Plan for Cavan Town is the main planning policy document for Cavan County Council. It covers 2022 to 2028 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 Cavan?
Zoning maps are part of the plan. Open the plan on the Cavan 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 Cavan 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 Cavan?
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 Cavan plan says, and the council's pre-planning meeting is the best way to test your case.
