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' and 'Stronger Rural Areas', a house is permitted for: people actively engaged in agriculture, horticulture, forestry, bloodstock or the peat industry; members of farm families building on the family farm (landowners for this purpose own the land for 5 years before applying); people employed locally in a job that serves the community; people with personal, family or economic ties to the area, including returning emigrants; and people returning to farming who buy or inherit a substantial farm. The local area is generally within 10 km of the family home.
Source: Volume 1, Chapter 9, Policy Objective CPO 9.1In 'Structurally Weak Areas' (concentrated in the north and west of the county), demand for permanent homes is accommodated using a flexible approach based on good siting and design, and no local housing need applies. The council still wants to distinguish genuine long-term commitment from speculative house building.
Source: Volume 1, Chapter 9, section 9.4.1, Policy Objective CPO 9.3Rural nodes are small unserviced settlements offering an alternative to one-off houses in the open countryside. Infill, conversion and single-site housing are permitted within a node's limits, but each proposal needs a hydrologist's assessment showing the septic tank outfall will not, with other tanks nearby, stop any water body reaching good status. The council also directs rural housing away from sites with high water tables, flooding or impeded drainage.

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