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.
In rural areas under strong urban influence, stronger rural areas and Areas of Special Control, you must show a functional economic or social need to live in the area. Economic need means work that needs you to live nearby, such as full-time farming, horticulture or forestry. Social need means you were born in the local rural area, or have lived there for at least 5 years (15 years in Areas of Special Control), including returning emigrants. The 'local rural area' is generally within 8 km (5 km in Areas of Special Control). Exceptional health needs with medical evidence are also considered. You must not already own or have owned a house in the open countryside, and the design must be high quality.
Source: Chapter 2, Policy SSP-27Elsewhere in the open countryside there is a presumption in favour of single houses for people from inside or outside the area who want a permanent home, with high quality siting and design. Speculative development is prohibited, the application must be in the name of the person who will live there, and a condition requires them to occupy it first. Derelict and habitable houses can be refurbished or replaced within the same curtilage under set criteria.

Areas of Special Control cover Special Protection Areas, Special Areas of Conservation, Natural Heritage Areas, areas of high amenity, source protection zones and restricted regional roads. If your site is in one, you must also show there is no alternative site outside these areas.

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 Offaly 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 Offaly development plan
What is the Offaly development plan?
The Offaly County Development Plan 2021-2027 is the main planning policy document for Offaly 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 Offaly?
Zoning maps are part of the plan. Open the plan on the Offaly 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 Offaly 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 Offaly?
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 Offaly plan says, and the council's pre-planning meeting is the best way to test your case.
