"The flood zone flag saved us. We were about to hire an architect. The report identified an SFHA designation on our lot that would have been a serious permitting problem. No other tool caught it."
Important: ADUVerify reports are preliminary assessments for informational purposes only. They are not zoning determinations, building permits, legal opinions, or financial guarantees. Always confirm findings with your local planning department before making any financial or construction decisions.
Why ADUVerify exists
Architect-led feasibility studies typically cost $2,000–$5,000 before a single permit is filed. Permit expeditors charge $500–$1,500 to assess feasibility. Most homeowners discover zoning conflicts, fire zone restrictions, or lot size issues only after spending that money.
ADUVerify was built to give you a data-driven first step — before the expensive ones. Six layers of public records, environmental screening, California ADU law, and rental market analysis, delivered in minutes for $149.
ADU Intelligence Systems doesn't guess. Our engine performs a systematic six-layer analysis of your property's legal and financial profile, synthesizing public data into a single, actionable report.
⚠ Environmental data is sourced from public agency APIs (FEMA, CAL FIRE) and reflects mapped zone designations only. These results are not a substitute for a professional site survey, environmental assessment, or insurance evaluation. Parcel-level accuracy may vary.

Rent comps·Cap rate·PaybackAbout Layers 1 & 2: Lot size and zoning are recommended for a complete report. Without them, Layers 1 & 2 run at reduced confidence — your report is still delivered, with a note on which data gaps affected the score. Both can be found free in under 2 minutes.
Everything you need to walk into a planning meeting or contractor estimate fully prepared.
Financial projections are estimates only. ADUVerify is not a financial advisor, CPA, or licensed contractor. Cap rates, rental figures, and build costs are regional averages and do not constitute financial advice or a guarantee of income. Consult a qualified financial advisor before making investment decisions.
California law allows up to 3 units on many residential parcels (primary + ADU + JADU). Your exact unit potential is calculated after lot size and zoning are verified — include them at checkout to maximize your confidence score.
"I'd been going back and forth for two years wondering if we could build a unit in our backyard. The report came back in four minutes and told me exactly what we could build and what it would cost. I brought it to my contractor the next day."
"The Maximum Unit Potential section genuinely surprised me. I didn't know we could add two separate units. The financial projection showed a 10-year payback. That's when this went from a 'maybe someday' to a serious project."
"The flood zone flag saved us. We were about to hire an architect. The report identified an SFHA designation on our lot that would have been a serious permitting problem. No other tool caught it."
