Structural Survey When Buying a House in Ireland: What to Know

Buying a house in Ireland is a significant financial commitment, typically the largest single purchase most people make. Yet many buyers proceed with only the most basic property assessment, leaving potential structural issues undiscovered until after contracts have been signed.

This guide explains what a structural survey involves when buying a house in Ireland, who arranges it, what it covers, how it differs from other types of survey, and what to do if it identifies a problem.

What Is a Structural Survey for Home Buyers?

A structural survey is an inspection of a property's structural condition: its foundations, walls, floors, roof structure, and any other load-bearing elements carried out by a Chartered Structural Engineer and summarised in a written report.

The structural survey is distinct from other types of property survey commonly encountered in Irish house purchases:

If you want a professional assessment of whether a property is structurally sound, you need a structural engineer not a general surveyor, not the bank's valuer, and not a HomeBond inspection report, which is not available for second-hand homes.

Who Arranges the Structural Survey When Buying a Home?

The buyer arranges and pays for the structural survey. It is not the vendor's responsibility, the solicitor's responsibility, or the bank's responsibility. Your solicitor may advise you to commission one and often will, particularly for older properties but it is your choice and your commission.

The structural survey is typically commissioned after your offer has been accepted but before contracts are signed. This is the right time to do it: you have a property agreed, you are in the due diligence phase before legal commitment, and you have time to negotiate on the findings before you are bound.

What About the Engineer's Report the Vendor Provides?

In some Irish house sales, the vendor provides an engineer's report as part of the sale documents. This report is commissioned by the vendor for the purposes of the sale, it is not the same as an independent structural survey commissioned by you. You are entitled to commission your own independent structural survey, and for any property where structural condition is a concern, you should.

What Does a Structural Survey Cover?

A Chartered Structural Engineer's pre-purchase survey covers the structural elements of the property:

• 1 External walls materials, condition, visible cracking, evidence of movement or repair
• 2 Internal walls load-bearing assessment, cracking, condition of finishes where structural
• 3 Foundations where accessible, or from records; condition of exposed sub-structure
• 4 Floors levelness, condition, any evidence of movement or deflection
• 5 Roof structure visible roof timbers (from loft access), condition, signs of movement or rot
• 6 Extensions structural assessment of any additions to the original structure
• 7 Drainage: visible drainage, any signs of drainage-related structural problems
• 8 Cracking assessment of all visible cracks: whether cosmetic or structural, what they indicate about movement
• 9 Specific concerns: any issues flagged in a general property survey, by the estate agent, or by the buyer

When Is a Structural Survey Particularly Important?

For a standard modern property in good visual condition, a structural survey may confirm that no significant issues exist but that confirmation is valuable in itself. The cases where a structural survey is most important:

• 1 Properties with visible cracking: any diagonal cracking near doors or windows, or cracks wider than 3mm, should be assessed by a structural engineer before purchase
• 2 Properties that have been extended extensions should be assessed for structural adequacy, compliance with building regulations, and integration with the original structure
• 3 Older properties (pre-1970 in particular): older construction methods, potentially shallow foundations, and long service lives mean higher structural risk
• 4 Properties in Dublin's southside clay soil areas are at a higher risk of tree-root subsidence
• 5 Properties with a disclosed subsidence history always commission an independent structural engineer, even if the vendor provides a remediation certificate
• 6 Converted properties garage conversions, loft conversions, basement conversions where structural alterations may not have been carried out to building regulations

What to Do If the Structural Survey Finds a Problem

A structural survey that identifies an issue gives you options which is exactly what it is designed to do. Typical outcomes:

• 1 Minor issues (cosmetic cracking, maintenance items): proceed with purchase, and use the report as a maintenance guide.
• 2 Moderate issues (structural repairs required, older drainage, remedial works needed): renegotiate the purchase price to reflect the cost of remediation, or request that the vendor carries out the works before completion.
• 3 Significant issues (active subsidence, structural failure, major underpinning required): decide whether to proceed at a substantially reduced price, request a subsidence investigation and monitoring programme, or withdraw from the purchase.

The structural engineer's report is the tool that gives you the information to make these decisions and the evidence base to negotiate from. A verbal assurance from the vendor or estate agent is not a substitute for a written structural engineer's report.
