Welcome to Chief Appraiser

A couple things worth knowing before you dive in.

Still Being Built — And That's Where You Come In

Chief Appraiser is in beta. That means the tool you're using today is real and already useful, but it's still growing — more guidelines, sharper search, more ways to ask a question the way you'd actually ask it. Every question you search, and everything you tell us through the Feedback button, is how we decide what gets built next.

Why not just use AI?

Because AI alone can sound confident and still be wrong. Chief Appraiser starts with the real guideline document — the actual page, the actual language — so you always know exactly where an answer came from. The plain-English summary underneath is AI, doing what it's actually good at: explaining a citation, not guessing at one.

What Is Chief Appraiser?

Chief Appraiser searches the actual text of the guideline documents that govern residential appraisal — HUD/FHA, VA, Fannie Mae, Freddie Mac, and local zoning codes — and returns exact passages with source and page number citations. Results are never AI-generated summaries. Every result is a direct excerpt from the original document.

How the Search Works

Chief Appraiser uses smart keyword matching with built-in synonym recognition. When you search an acronym like ADU, it automatically also searches for "accessory dwelling unit," "guest house," "secondary unit," and other variations — so you get results whether the document uses the abbreviation or the full term. You are always reading the actual regulation, not an interpretation of it.

Search Tips

Tip 1 — Use the term, not the question
✓ ADU     accessory dwelling unit     guest house
✗ What are the appraisal requirements for accessory dwelling units in Clark County?

A single term or short phrase works best. The search recognizes common synonyms automatically — "ADU" and "accessory dwelling unit" return the same results.

Tip 2 — Acronyms and full terms both work
✓ ADU    ROV    MPR    NOV    tidewater    comps    GLA
✓ reconsideration of value    minimum property requirement    comparable sales

The search knows that ADU = accessory dwelling unit, ROV = reconsideration of value, MPR = minimum property requirement, and 60+ other appraisal term equivalencies. Use whichever feels natural.

Tip 3 — One concept at a time
✓ tidewater     desktop appraisal     mixed use
✗ What happens when VA tidewater is triggered and the lender disagrees with value?

Isolate the concept. A short phrase finds more relevant passages than a full question.

Tip 4 — Low scores? Try shorter

Low relevance scores (small numbers like 0.04) mean the engine wasn't confident. Shorten your search to the core term and try again.

Tip 5 — Local zoning searches
✓ setback    accessory    zoning    guest house    ADU

Clark County, NV Title 30 zoning code is in the library. Search any zoning term and results from the code will appear alongside the national guideline documents.
