Independent buyer guide · Derelict property
How to buy a derelict property in Ireland — the steps that protect the grants.
A derelict purchase looks cheap on the listing and expensive in the build. This is the independent walk-through: what the Derelict Sites Act actually says, where to find candidate properties, what to check before you bid, what the renovation tends to cost, and how to stack the grants without disqualifying yourself.

What counts as "derelict" in Ireland
Under the Derelict Sites Act 1990, a derelict site is one where the structure or land "detracts, or is likely to detract, to a material degree from the amenity, character or appearance of land in the neighbourhood." In practice your local authority makes the call and records it on the Derelict Sites Register. A property does not need to be on a register to be derelict — councils have discretion to add sites and to remove them once works are done. For grant purposes (Croí Cónaithe derelict band), independent evidence of dereliction also satisfies the council where the property is not yet on the register.
Where to find derelict properties
Local-authority Derelict Sites Registers
Every council maintains one. Dublin City, Cork City, Galway City, Limerick, Waterford and Kilkenny publish theirs online; smaller authorities require a request to the Vacant Homes Officer. These registers list properties already classified, with the owner where known.
GeoHive vacancy data
Tailte Éireann's GeoHive includes vacancy indicators from Census 2022. Useful for spotting clusters of vacant property within a town, though it does not name individual addresses.
Walking the area
Many candidates are not on any register yet. Boarded-up windows, overgrown gardens, missing roof tiles, post buildup — the usual signs. Photograph what you see and bring it to the council's Vacant Homes Officer before the auctioneer prices it up.
Council Vacant Homes Officer
Every local authority has one. They know which addresses are about to be added to a register, who the owners are, and whether a Compulsory Purchase Order is in train. Worth a phone call before any offer.
Due diligence — before you bid
A derelict listing always looks cheap. Most of the risk is in things the listing does not show. The five checks below catch the deal-breakers before contracts.
Title & ownership
Pull the folio via the Property Registration Authority (landdirect.ie). Confirm the seller actually owns it and that there are no live charges or burdens. Long-vacant properties often have probate issues — your solicitor should establish a clean chain before contracts.
Planning history
Search the council's planning portal for everything ever applied for at the address. Refused applications matter as much as approved ones — they tell you what the council will not allow.
Structural assessment
Independent surveyor (RICS / SCSI-qualified) on site before contracts. They cost €600–€1,200 and will save you orders of magnitude. For severely derelict properties a structural engineer report is usually also needed for the Croí Cónaithe derelict-band application.
BER & energy condition
Most derelict properties have no current BER. Get an assessor in once you are sale agreed — the rating affects which SEAI grants apply and how the One Stop Shop route prices the works.
Vacancy evidence
Croí Cónaithe requires the property to have been vacant 2+ years. Gather utility records, electoral register history, a Vacant Homes Officer statement, or a sworn affidavit before applying — the council will ask.

Renovation cost reality — what to budget
A full renovation of a derelict property in Ireland typically runs €80,000–€200,000+ depending on size, condition and location. The cheap end assumes the structure is sound and you reuse the existing layout; the expensive end assumes new roof, full re-wire, new plumbing, full insulation, new windows, new kitchen and bathrooms, and bringing the BER to B2 or better. A Croí Cónaithe grant covers up to €70,000 of that, and SEAI grants can take another €30,000–€50,000 out of the energy-efficiency portion — but the gap between the headline price and the all-in finished cost is where most projects come unstuck.
€40k – €80k
Light refurbishment (sound structure, cosmetic)
€80k – €140k
Standard refurbishment (rewire, replumb, insulation, windows)
€140k – €200k+
Full derelict rebuild (roof, structure, full retrofit)
Funding
The grant stack
Croí Cónaithe (local authority) pays up to €70,000 for the structural, electrical, plumbing and finish works. SEAI grants (national) pay separately for the energy-efficiency portion: insulation, heat pump, solar, windows & doors, BER. The two can fund the same property — they cannot fund the same line item. In practice, route insulation and renewables through SEAI (it has the contractor lists and the technical assessments) and use Croí Cónaithe for everything else.
The full sequence, step by step
Do not start works before written grant approval. Both Croí Cónaithe and SEAI disqualify works that begin before approval. The single most common reason an otherwise-eligible project loses funding.
- 1
Identify the property. Use Derelict Sites Registers, GeoHive, and a Vacant Homes Officer conversation — not just the auctioneer's listing.
- 2
Pre-bid due diligence. Folio search, planning history, structural surveyor on site, BER assessor once sale-agreed.
- 3
Confirm vacancy. Gather 2+ years of vacancy evidence before applying for Croí Cónaithe — utility records, electoral register, council statement.
- 4
Get itemised quotes. Croí Cónaithe and SEAI both need cost estimates that break out the works by line item, not a single total.
- 5
Apply for grants in parallel. Croí Cónaithe via local authority, SEAI via the HES portal. Approval can take 8–12 weeks. Do not start any works yet.
- 6
Wait for written approval. The single most common reason derelict projects lose their grants is starting works between contracts and approval. Pay no deposits to contractors until both approval letters land.
- 7
Carry out the works in sequence — structural first, then fabric (insulation), then heating, then finishes. SEAI fabric-first sequencing applies here too.
- 8
Submit draw-downs with VAT invoices, photos and post-works BER. Final tranche releases after a post-works inspection.
Frequently asked questions
›How much does it cost to renovate a derelict house in Ireland?
Typically €80,000–€200,000+ all-in, depending on condition. A sound-structure cosmetic refurbishment can come in around €40k–€80k. A full rebuild with new roof, rewire, replumb, insulation, windows, kitchen and bathrooms more commonly runs €140k–€200k+. Croí Cónaithe covers up to €70,000 and SEAI energy grants cover separately on top.
›Where can I find derelict properties for sale in Ireland?
Council Derelict Sites Registers (Dublin City, Cork City, Galway City, Limerick, Waterford and Kilkenny publish theirs online), Tailte Éireann GeoHive vacancy data, your local-authority Vacant Homes Officer, plus walking target areas. Many candidates are not yet listed for sale at all — the Vacant Homes Officer can often introduce you to the owner.
›Do I need planning permission to renovate a derelict house?
For like-for-like refurbishment within the existing footprint, usually no — exempted development applies. Extensions, demolition of significant portions, change of use, or protected-structure works require planning. Always pull the planning history first and call the council planning office before assuming exemption.
›Can I get the Vacant Property Refurbishment Grant AND SEAI grants?
Yes. They are separate schemes — Croí Cónaithe (local authority) and SEAI (national). They can fund the same property. The hard rule: no double-funding the same measure. In practice route insulation and renewables through SEAI, and use Croí Cónaithe for structural, electrical, plumbing and finishes.
›What is the Derelict Sites Act 1990?
The Act gives local authorities the power to maintain a Derelict Sites Register, charge a 7% annual Derelict Sites Levy on listed properties, and in some cases acquire derelict sites compulsorily. It also defines "derelict" — a site whose condition materially detracts from the amenity of the area. Councils have discretion in classification.
›How long does the full process take?
From identifying a property to first grant draw-down: 6–9 months is realistic, longer if probate or planning issues. Full project to completion: 12–24 months is normal. Plan the timeline around the grant approval window — anything you do before written approval is unfunded.
