Zoning map of Ireland: what a site is zoned for

Every county and city council zones land in its development plan, and towns often have a more detailed local area plan. The zoning says what kind of development the council wants on the land: housing, town centre, industry, open space and so on. Open countryside is usually not zoned at all, and the plan's rural policies apply instead. Zoned residential land may also be on the Residential Zoned Land Tax map.

How InSite helps

Gives every zone on any part of the plot, with the council's own zone name and objective and a link to the plan.
Adds the national zoning category and the plan's name and dates. If there's no zone, you'll know the county's rural policies apply instead.
Tells you whether the land is on the current Residential Zoned Land Tax map, or proposed to be added or removed in the draft.

How zoning works

Each zone has an objective in the plan, for example "to provide for new residential development" or "to protect and enhance open space". A planning application is assessed against it: development that fits the zoning has a much better chance; development that conflicts with it is likely to be refused. Plans are reviewed and replaced periodically, and can be varied in between, so zoning can change.

Councils use their own zone names and letters (R1, Z1, "New Residential", "High Amenity"...). The Department of Housing maps all of them into a common national set of Generalised Zoning Types so they can be compared across councils; this is the data behind myplan.ie.

Unzoned land

If a site isn't in any zone, that's normal for the countryside. Building there is judged against the county plan's rural housing and countryside policies, which often include a local need requirement for one-off houses.

Residential Zoned Land Tax (RZLT)

The RZLT is an annual tax of 3% of market value on land that is zoned for housing, serviced, and not built on. Each council publishes a map of the land in scope each year, and a draft map for the following year that owners can make submissions on. Homes and their gardens are generally excluded. If a site is on the map, take advice.

What it can't tell you

Donegal isn't in the national zoning dataset; check its own plan.
The national dataset can lag a newly adopted plan or variation. The council's adopted plan is the legal version.
Zoning isn't permission. Design, access, services, flood risk and everything else still apply.
