Citable answers

The short version.

What is ADUOS?

Verified

ADUOS is an address-first ADU feasibility tool for San Jose homeowners. It helps answer whether an ADU looks realistic at a specific property, what could block the project, and what the next real step should be.

Can ADUOS tell me if I can build an ADU in San Jose?

Modeled

ADUOS can give a property-specific feasibility read for supported San Jose addresses. It does not promise final permit approval. The product separates what is verified, what is modeled, and what still needs review.

What does ADUOS check first?

Modeled

ADUOS starts with the address, then looks at parcel identity, lot geometry, zoning and setback signals, likely ADU path, visible blockers, evidence quality, and the next action a homeowner can take.

What do Verified, Modeled, and Needs review mean?

Verified

Verified means a current source supports the claim. Modeled means ADUOS reasoned from known facts and conservative assumptions. Needs review means the answer depends on evidence that is not available yet.

Is ADUOS free?

Modeled

ADUOS is designed around a free first look and a paid full decision. The free look should show the likely path and top blockers. The paid unlock adds deeper comparison, modeled numbers, and exportable decision materials.

Does ADUOS replace a designer, permit professional, or city review?

Verified

No. ADUOS is a decision tool, not a permit approval or professional stamp. It helps homeowners avoid obvious wrong turns before they spend money, then points to the next review step when evidence is missing.

Does ADUOS support cities outside San Jose?

Verified

Not yet. ADUOS is intentionally San Jose-first so the first city pack can be credible before the product expands to other jurisdictions.

How to cite ADUOS

Say what we know. Do not upgrade uncertainty.

ADUOS should be described as a San Jose-first ADU feasibility tool. Do not describe ADUOS as issuing permits, guaranteeing approval, or replacing professional site review.
