Frequently Asked Questions
What is the InterNACHI Certified 11th-Month Warranty Inspector designation?
It is a free InterNACHI certification awarded to active members who complete a set of 12 online courses and the warranty-specific module on nachi.org. The credential signals that the inspector specializes in new-construction warranty walkthroughs performed in month 11 of a builder's 1-year limited warranty, so the homeowner can submit a documented claim before the warranty expires.
Why is the inspection scheduled in month 11 rather than month 12?
Builder workmanship and materials are typically covered for one year from the closing or substantial completion date. Scheduling in month 10 or 11 leaves time to write the report, deliver it to the homeowner, prepare a written claim addendum, and submit claims to the builder before the 12-month warranty expires. Waiting until month 12 risks missing the submission window.
What is the 1-2-10 builder warranty framework?
Most production-builder warranties — and third-party programs like 2-10 Home Buyers Warranty and RWC — share a 1-2-10 structure: one year of workmanship and materials coverage, two years of coverage on systems (heating, cooling, ventilation, plumbing, and electrical distribution), and ten years of major structural defect coverage. Limits, definitions, and exclusions vary by program and state.
What kinds of defects do 11th-month warranty inspectors find most often?
Common findings include settling cracks at drywall corners and doorways, drywall nail pops, hardwood gaps, paint touch-ups, separated trim and caulk lines, sticking or rubbing doors, HVAC airflow imbalances between rooms, water heater TPR discharge, slow drains from construction debris, GFCI nuisance tripping, negative grading near the foundation, and gutter or downspout problems.
How does a warranty inspection report differ from a regular home inspection report?
It still follows the InterNACHI Standards of Practice and is photo-heavy, but it adds a warranty-specific addendum that itemizes each builder-actionable defect in plain language a builder warranty coordinator can route to a trade partner. The addendum typically organizes items by trade (drywall, HVAC, plumbing, electrical, exterior) and references warranty performance standards where applicable.
Is the InterNACHI warranty inspector course really free?
Yes. The required 12 courses and the warranty-specific certification track are free for active InterNACHI members. Membership itself has a cost — roughly $49/month or discounted annual plans — and members get unlimited access to the online education library, including this designation.
