Building Integrity Audit: Should You Buy That Used House in Nigeria?

A used house can be a bargain or a liability wearing a fresh coat of paint. In Nigeria, where sales happen fast and “as is” is the standard clause, the paint usually wins. A building integrity audit is the instrument that tells you what is under the paint, before your money is.

What a Building Integrity Audit Covers

A licensed engineer inspects the structure and systems:

• Foundations and walls: cracks, settlement, dampness, signs of movement
• Structure: columns, beams, slabs, reinforcement exposure, corrosion
• Roof: structure, covering, leaks, water damage
• Services: electrical safety, plumbing condition, drainage function
• Compliance: was the building approved? Does it match the approved plan?

The output is a report that grades the building and lists defects with severity: cosmetic, repairable, or structurally significant.

When to Order One

• Before buying any used house, especially one advertised at a discount
• Before signing a long lease on a commercial property
• After buying, to plan maintenance and insurance
• When a building has been vacant for years, or after flooding or fire
• Before renovating, so the renovation budget is based on the real structure

The Defects That Should End the Deal

• Structural cracks through walls, floors or foundations
• Settlement or tilting of the building
• Corroded or exposed reinforcement
• Unapproved construction that cannot be regularised
• Termite or rot damage in structural timber
• Electrical systems that fail basic safety checks

Cosmetic issues, roof leaks and plumbing problems are repairable and negotiable. Structural issues are reasons to negotiate a much lower price, or walk away. A report that says “repairable” and one that says “structurally compromised” are different conversations with the seller.

What It Costs

A residential building integrity audit typically runs ₦200,000 to ₦500,000, depending on size and location. Compared to the purchase price, and the cost of discovering a failing foundation after payment, it is the cheapest line in the transaction.

The Pattern to Follow

Inspect before you commit, not after. Order the audit, read the report with someone who understands it, and make your offer on the findings. Sellers who resist inspection are telling you something about the building.
