Six layers of live government data — zoning, flood zone, fire risk, lot size, rental income, and unit potential — delivered in a polished PDF in under 5 minutes. Includes an Architect's Brief ready for immediate handoff.
Powered by trusted public data sources
Data retrieved from live government and commercial sources at time of report generation.
"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."
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.
Every report pulls live government and market data — not estimates, not averages.
Zoning classification, lot size, and unit potential pulled directly from city GIS systems. Automatic lookup across 17 California cities and counties, including Los Angeles, San Diego, Oakland, Sacramento, Fresno, and Orange County.
FEMA flood zone classification and CAL FIRE hazard severity — the two environmental flags most likely to block permits or raise insurance costs before you break ground.
Rental income projection based on 200+ local comps via RentCast. Cap rate, gross yield, and a realistic cost band — so you know the numbers before talking to anyone.
Before spending thousands, see what $149 actually gets you.

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.
"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."
"Spent $149, found out the property pencils out at a 6.8% cap rate. That's the number that got my lender on board."
Built for trust
Before spending $2,000–$5,000 on an architect or contractor, you deserve an independent, data-driven starting point.
Most homeowners don't know what comes after feasibility. Here's exactly how your ADUVerify report feeds into the build process — and what to do with it.

Without these, your report still delivers all six layers — but Layers 1 & 2 run at reduced confidence. Most customers with a green eligibility result choose to add them.
Optional — include it to get a full Layer 1 analysis. Find it on your county assessor's site or property tax bill.
