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.

How it works

Six Data Layers.
One Preliminary Assessment.

ADU Intelligence Systems doesn't guess. Our engine performs a deep-tissue scan of your property's legal and financial profile, synthesizing your address into a single, actionable report.

LAYER 01
Parcel & Geometry Mapping *
We extract precise lot dimensions and confirm your primary residence type to ensure your property qualifies under current California ADU law, including minimum lot thresholds set by SB 9 and AB 68.
Lot size · Property type · APN
LAYER 02
Jurisdictional Compliance *
Our engine identifies the exact municipal and county overlays governing your land, cross-referencing state-level ADU rights under current law against known local ordinance overrides and deed restrictions.
County · Zoning · Local rules
LAYER 03
Environmental & Risk Screening
We query publicly available government data sources to flag Special Flood Hazard Areas (SFHA), fire severity zones, and seismic constraints that could stall your permitting process before it starts.
FEMA flood · Fire zone · SFHA
LAYER 04
Zoning & Setback Analysis
We calculate the Build Envelope — verifying where on your lot a Detached ADU or JADU can legally sit without violating fire, utility, or neighbor setback requirements in your jurisdiction.
Setbacks · Build envelope · ADU type
LAYER 05
Rental Market Indexing
We index hyper-local rent comparables for your ZIP code and neighborhood to project realistic monthly cashflow — the same benchmarks used by regional lenders when underwriting ADU construction loans.
Rent comps · Cap rate · Payback
LAYER 06
Automated Analysis
Finally, our proprietary analysis engine compiles all findings into a comprehensive feasibility report — localized to your specific address and build goals, structured for contractors, advisors, and lenders.
PDF report · Financial model · Next steps
* Layers 1 & 2 require user-provided lot size and zoning code for full automation. If not provided at checkout, we'll show you exactly where to find them — free, takes under 2 minutes.
What's in your report

Research-ready. Contractor-ready.
Decision-ready.

Everything you need to walk into a planning meeting or contractor estimate fully prepared.

01
Feasibility Verdict
A clear, scored determination — Likely, Possibly, or Unlikely Feasible — with confidence rating and the specific factors that drove the conclusion.
02
Environmental Risk Flags
FEMA flood zone designation, fire severity zone status, and coastal overlay analysis — identified before you spend a dollar on plans.
03
ADU Type Breakdown
Detached ADU, Attached ADU, Garage Conversion, and JADU — each assessed individually with a preliminary feasibility score and estimated cost range.
04
Financial Projections
Estimated build cost, projected monthly rent, cap rate, and payback period — calculated using regional benchmarks and current construction data.
05
Maximum Unit Potential
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 — both required fields at checkout.
06
Recommended Next Steps
A prioritized action plan tailored to your property — from which department to call first, to which ADU type to price out, to what data would increase your confidence score.
California ADU Law — SB 9 & AB 68

Maximum Unit Potential:

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 — both required fields at checkout.

California ADU law — including SB 9 (2021), AB 68 (2020), AB 2221 (2022), and AB 976 (2023) — significantly expanded ADU rights. Your report calculates your exact unit potential after lot size and zoning are verified at checkout — subject to local planning verification.

From homeowners

They got the verdict.
Then they acted.

★★★★★

"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."

Beta tester feedback. Results vary by property.
★★★★★

"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."

Beta testers, San Jose CA
Beta tester feedback. Results vary by property.
★★★★★

"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."

Common questions

Before you order.

No. This is a professional-grade preliminary feasibility assessment — not a zoning determination, planning approval, or building permit. It is designed to give you the information you need to have a confident, informed conversation with your local planning department. Always verify findings with your local authority before making financial or construction decisions.
Our engine runs six structured verification layers simultaneously — flood zone screening, environmental risk flags, jurisdictional compliance, rental market indexing, and financial modeling — then synthesizes them into a single coherent report. That process would take most homeowners days of research across multiple government websites, many of which require specialized knowledge to interpret correctly.
Most reports are delivered within 2–5 minutes of submission. In rare cases of high demand, delivery may take up to 30 minutes. If you haven't received your report within an hour, email support@aduverify.com and we'll resolve it immediately.
Under current California ADU law (SB 9, AB 68, AB 2221, and AB 976), certain single-family properties may be eligible to add up to two additional units — a Detached ADU and a Junior ADU — alongside the primary residence. Your exact unit potential is calculated after lot size and zoning are verified — both required fields at checkout.
The report runs for any U.S. address — environmental screening, geographic verification, and financial projections are nationwide. The California-specific Maximum Unit Potential analysis and current California ADU law rules apply only to California properties. Non-CA reports still include full feasibility analysis and financial modeling.
Yes. Providing your lot size in square feet and your current zoning code significantly increases the confidence level of your report — from Medium to High in many cases. Both fields are required at checkout and take under 2 minutes to look up for free on your county assessor's website or city planning portal.

Why do we ask for lot size and zoning?
These two fields unlock the full power of your ADU report:

Lot Size — determines if a detached ADU fits on your parcel and whether impact fees apply (≤800 sq ft = waived in most CA cities).

Zoning Code — confirms ADU eligibility by right vs. discretionary review. Without it, we cannot calculate your true unit potential.

Both take under 2 minutes to find for free online.
📋 Find it free: Search your address on your county assessor's website — look for "lot size" or "land area" in sq ft.
📋 Find it free: Visit your city's planning portal or call your planning department (takes 2 min).

Preliminary assessment only. Not a zoning determination or permit. Findings require local verification.
