About ADUVerify
ADUVerify is a product of ADU Intelligence Systems, operated by Kerylos Holdings LLC — a property technology company focused on making residential development intelligence accessible to individual homeowners.
Why it was built
ADUVerify was created after six months of researching a single question: can this property support an ADU? The answer required cross-referencing FEMA flood maps, CAL FIRE databases, the county assessor website, the city planning portal, and three different rental listing platforms — none of which talked to each other. At the end of that research, the answer was still preliminary. ADUVerify automates that entire process and delivers a structured preliminary assessment in minutes, so homeowners can make informed decisions before the expensive ones.
A preliminary automated feasibility tool. Not a licensed planning consultant, not a zoning attorney, not a permit expediter. Our reports are designed to give you the information you need to have a confident, informed conversation with the professionals who do those things.
ADUVerify reports are not zoning determinations, building permits, legal opinions, or financial guarantees. Every report includes a confidence score and explicit flags for what requires local verification. We believe transparency about limitations builds more trust than hiding them.
California is our current focus. Additional states will be announced when report quality meets California standards.
