ExploreAbout this exam
The InterNACHI 11th-Month Warranty Inspector credential is a specialty certification for home inspectors who want to perform near-end-of-first-year warranty inspections on newly built homes, helping buyers document defects before the builder's one-year workmanship warranty expires. This page is an independent study aid for candidates preparing for that certification exam; it is not affiliated with or endorsed by InterNACHI, and no official exam details are claimed here.
The published InterNACHI page for this certification could not be retrieved (the URL returned a 404 error at the time of research), so verified facts about exam format, question count, time limit, passing score, fee, retake policy, and validity period are not available. Rather than guess, this guide marks those details as pending review and focuses on the four published content domains: 11th-Month Warranty Inspection Fundamentals; Builder Warranty Coverage and Exclusions; Inspection Scope, Standards, and Reporting; and Client Communication and Business Practices, each weighted 25 percent.
To prepare, build a working knowledge of how builder warranties typically divide coverage, how to plan an inspection timed just before the warranty lapses, how to document findings so a builder can act on them, and how to explain results to a homeowner without overstating your role. Use the practice questions on this page to test recall, then revisit weak domains. Confirm all official logistics directly with InterNACHI before scheduling.
What you'll study
About InterNACHI 11th-Month Warranty Inspector preparation
What is an 11th-month warranty inspection?
It is an inspection of a newly built home performed shortly before the builder's one-year warranty period ends, so the buyer can submit a documented list of defects while the builder may still be obligated to repair them. Inspectors who hold this credential market the service to recent homebuyers.
Who should pursue this certification?
Working home inspectors who already perform new-construction or pre-drywall inspections and want to add a recurring service for past clients. It also suits inspectors building relationships with real estate agents who represent buyers of new homes. Confirm eligibility requirements directly with InterNACHI.
What does the exam cover?
The published domains are 11th-Month Warranty Inspection Fundamentals, Builder Warranty Coverage and Exclusions, Inspection Scope, Standards, and Reporting, and Client Communication and Business Practices, each weighted 25 percent. Expect questions that blend technical observation with how you report and communicate findings.
How many questions are on the exam, and how long does it take?
Not verified. The official InterNACHI page for this certification returned a 404 error when researched, so question count, time limit, and passing score are marked for review rather than guessed. Check the current InterNACHI certification page before you schedule so you plan your time accurately.
What happens if I fail? Can I retake it?
Not verified. Retake policy, any waiting period, and whether a fee applies are not stated in the source material available, so they are flagged for review. Ask InterNACHI directly about retakes before your first attempt, and treat your first sitting as the one to prepare hardest for.
Which domain should I study first?
Start with Builder Warranty Coverage and Exclusions, because scope and reporting decisions depend on knowing what a warranty typically does and does not cover. Then study inspection scope and reporting, followed by fundamentals and client communication, which reinforce each other through scenario-style questions.
What are common failure modes on exams like this?
Candidates often confuse what the inspector observes with what the builder is obligated to fix, or write reports that are vague about location and condition. Others overlook communication duties, such as setting expectations about your role and the limits of your inspection, which the business practices domain tests.
How should I document findings for a builder?
Be specific and verifiable: identify the location, describe the observed condition, and where useful include photos and a clear statement of why it matters. Avoid diagnosing causes you cannot confirm. Clear, itemized reporting helps the builder respond and helps the homeowner preserve a record before the warranty ends.
Does this page grant the certification?
No. This is independent study material and practice content, not an official InterNACHI product, and completing it does not confer certification. Any credential, membership, or certification step must be obtained through InterNACHI's own processes, which you should verify on their website.
