How do I read a foundation inspection report without being an engineer?
Answered by Allen Markel, REALTOR®, Texas Premier Realty ·
Short answer
A foundation inspection report uses simple labels: I (inspected), NI (not inspected), NP (not present), and D (deficient). Read the comments section under Foundations for plain-language descriptions of what the inspector found. If you see D, ask the inspector to explain it in detail before the option period ends. Deficient means something needs attention, not that the home is unsafe. Get a structural engineer or foundation specialist to evaluate any D items and estimate repair costs.
What the labels mean
The report uses four codes. I means the inspector looked at it and found no issues. NI means the inspector did not inspect that item. NP means it is not present in the home. D means deficient, which signals that something the inspector saw needs further evaluation or repair.
The foundation section is part of the Structural Systems area. Look for the Foundations row, which shows the type of foundation and a comments field. That comments field is where the inspector writes what he or she observed in plain language. Read it carefully. If you do not understand a comment, ask the inspector to explain it before you leave the inspection or during the option period.
What to do if you see a D
If the foundation is marked D, do not panic. Deficient does not mean the home will collapse or is unsafe to occupy. It means the inspector spotted something that warrants a closer look by a specialist. During your option period, hire a structural engineer or foundation specialist to evaluate the deficiency, take photos, and give you a repair estimate. This is the time to decide whether to ask the seller to fix it, negotiate a credit, or walk away.
The TREC form notes that evaluations by specialists may uncover additional issues not visible during the initial inspection. That is normal. Get the specialist's report and cost estimate before your option period expires so you have time to make an informed choice.
How to use the report during your option period
The inspection report is a tool for the option period, which is your window to hire inspectors and specialists and negotiate repairs. Read every comment, not just the codes. If anything is unclear, contact the inspector and ask for clarification. For any D items, line up a specialist evaluation right away; do not wait until the last day of your option period.
Remember that the inspection is a visual survey at one point in time. It is not a guarantee of the home's condition, and repairs made after the inspection date may change what the report says. Use the report to guide your next steps, and talk to us to find the right option for your circumstances.
Common follow-up questions
What does D mean on a foundation inspection report?
D stands for deficient. It means the inspector observed something that needs further evaluation or repair. It is not a pass-or-fail judgment; it is a flag to get a specialist's opinion and cost estimate during your option period.
Do I need an engineer to read the report?
No. The TREC form uses plain language in the comments section. If a comment is unclear, ask the inspector to explain it. For deficient items, you will want a structural engineer or foundation specialist to evaluate and estimate repair costs, but you can read and understand the report yourself.
When should I hire a foundation specialist?
As soon as you see a D on the foundation line. Your option period is the time to get specialist evaluations and repair estimates. Do not wait until the last day; specialists may be booked, and you need time to review their findings and decide your next move.
Is a deficient foundation a deal-breaker?
Not necessarily. It depends on what the deficiency is, the cost to repair, and your budget and timeline. A specialist's report will tell you the severity and cost. You can then ask the seller to repair it, negotiate a credit, or decide the home is not right for you.
