Structural Report: When to Request One Before Buying

You should request a structural report (dictamen estructural) for a house when the property is located in a seismic zone, is more than two or three decades old, shows visible cracks, or was reported to have suffered damage after an earthquake or hurricane. This document, prepared by an expert appraiser (perito) or civil engineer, evaluates whether the foundation, columns, and load-bearing walls can still safely carry their loads. Requesting it before signing any deposit can keep you from investing in a property with hidden structural risk, and in many cases it also gives you leverage to negotiate the final price.

When it makes sense to request one

Not every purchase requires this step, but there are scenarios where it becomes almost mandatory. If the house was built before today's building codes existed, if it has already been through a sizable earthquake, or if you notice recent repairs that could be hiding earlier damage, a structural report gives you peace of mind. It's also advisable if you plan a major renovation, such as knocking down walls or adding a floor, since the expert can tell you whether the original structure allows it without compromising the safety of the property. Another key moment is when the asking price seems unusually low compared with the local market, because sometimes that discount hides a structural problem the seller would rather not mention.

What a structural report includes

A structural expert's report typically covers several key points that help you understand the true condition of the home before you commit your money.

• Visual inspection for cracks, settlement, and leaning
• Evaluation of the foundation and soil, when possible
• Review of columns, beams, and load-bearing walls
• Reinforcement recommendations if damage is detected
• Conclusion on habitability and structural safety
• Rough estimate of the structure's remaining useful life

How to choose the right expert

Not just anyone can sign a structural report with real validity: look for a civil engineer or expert appraiser (perito) with a professional license (cédula profesional) and verifiable experience in residential assessments, ideally with references from previous work. Ask that the visit include a full walkthrough of the property, not just the visible areas, and that the final report be signed and dated, since some later procedures such as insurance or loans may require it. Avoid hiring the same contractor who would later do the repairs if damage is found, to prevent a conflict of interest in which they recommend unnecessary work; separating the diagnosis from the execution of the work tends to produce more objective results.

Frequently asked questions

How long does a structural report take?

It can vary depending on the complexity of the house, but generally the expert does the visit and delivers the report within a few days to a couple of weeks.

Does the bank require a structural report to approve the loan?

It depends on the bank and the appraisal (avalúo). Some mortgage appraisals include a general review of the property's physical condition, but they don't replace a specialized structural report if there are serious doubts.

Can the same report be used to sell the house later?

It can serve as a reference if it's recent, although it's best to update it if several years have passed or if the home suffered a significant earthquake or moisture event after the report was issued.
