Derelict sites and housesNew

A site on a council’s derelict sites register costs its owner 7% of its value every year it stays there. Precedent puts 739 of them from 8 councils in one search — longest on the register first, each with its Land Registry title, zoning and planning history.

One search across the councils

Every entry, on the mapNew

Each council’s register, read from the council and placed where the council placed it — houses, shops, pubs, yards and plots.

Longest on the register first

Filter by years on the register: the longer a site has been on, the longer its owner has paid and not fixed it.

By place and plot size

Pick a council or draw an area, and set the size of the Land Registry title the site stands on.

Everything about the site, on one card

The register entry

The council’s reference, the address, when it went on, and the date of the register it was read from.

The site check

Zoning, flood, protected structures, ecology, planning history and sale prices nearby, measured on the title.

The owner

The coordinates to look the title up on landdirect.ie, and save the site to a project with a note.

The levy becomes a tax

Budget 2027 turns the derelict sites levy into a Derelict Property Tax: 7% a year of the property’s value, collected by Revenue, with councils’ first registers under it due in September 2027 and the first payment on 23 June 2028. A sale to a buyer who fixes the property takes it out of the charge.

Collected by Revenue

Councils still decide what is derelict; Revenue collects, under normal tax rules, instead of the councils.

New registers in September 2027

Owners can appeal until the end of November 2027; final registers follow in March 2028.

Towns first

First towns and cities of 4,000 people or more, then towns of 2,000 or more.

Derelict sites and houses: questions

How do I find derelict properties in Ireland?

Every council keeps a Derelict Sites Register under the Derelict Sites Act 1990, most as a PDF or spreadsheet on its own website. Precedent reads 8 of them — Cavan, Dublin City, Dún Laoghaire–Rathdown, Galway City, Laois, Roscommon, South Dublin and Waterford — into one search on a map, with each site’s Land Registry title, zoning and planning history.

What is the Derelict Property Tax?

Budget 2027 turns the derelict sites levy into a Derelict Property Tax: 7% a year of the property’s value, collected by Revenue, with councils’ first registers under it due in September 2027 and the first payment on 23 June 2028. It replaces the derelict sites levy, which councils collected. It is as announced and subject to the Finance Bill.

Can I see who owns a derelict site?

Precedent does not show owner names, even where a register prints them. It gives you the site’s coordinates to look the title up on landdirect.ie, where a copy of the folio names the registered owner.

Loaded for Cavan, Dublin City, Dún Laoghaire–Rathdown, Galway City, Laois, Roscommon, South Dublin and Waterford, the councils that publish where each site is; other councils’ sites are not in it yet. A site comes off a register once it is fixed, so check the council before relying on one. The tax is as announced in Budget 2027 and is subject to the Finance Bill.
