Two cities, two miles apart, can enforce different code editions, different amendments, and different submittal rules. A wall assembly that sails through in one town draws a correction in the next. A generic "code checker" treats the whole country like one rulebook — which is exactly why generic tools get you redlined.
InstaPreview doesn't work that way.
Our algorithm reviews your plans against the requirements that actually apply where you're building: the adopted code edition, the state-level amendments, and the local amendments stacked on top of them — anywhere in the country. You get corrections tied to the specific requirement in your jurisdiction, not a one-size-fits-all checklist that misses what matters and flags what doesn't.
All fifty states. InstaPreview covers the entire United States. Wherever your project is — a major metro, a rural county, or anywhere in between — our algorithm applies the code edition and amendments adopted in that jurisdiction, not a national default.
That nationwide reach is the hard part, and it's exactly what we built the software to do. Instead of a reviewer manually tracking thousands of local rulebooks, our AI applies the right requirements to the right project automatically — at the speed software moves, not the speed a queue moves.
Building somewhere unusual? Run it through and see. If anything about your jurisdiction needs a closer look, contact us → and we'll make sure it's covered.
