Earthquake & Seismic Design Snapshot
The building-code seismic design values at this exact location.
USGS seismic design values for the address (the same numbers engineers use under ASCE 7), the seismic design category, the strongest historical earthquakes within 50 km, and FEMA's earthquake risk rating for the tract.
- ✓Seismic design category & ground-motion values
- ✓Strongest quakes within 50 km since 1900

Every number is labeled and sourced.
No unlabeled figures. Every number on this report traces to a named source, anything assumed is flagged, and where AI fills a gap it says so — right next to the number.
Every figure carries its source
Each number is tagged with where it came from — a licensed property record, a named government dataset (Census, NCES, FEMA, HUD, FBI), or your own data — along with its vintage. Confidence measures how consistent those sources are, not a promise of truth.
AI is always disclosed
Where AI fills a gap — like market references in a thin market — it's clearly labeled “AI-estimated” and never passed off as real data. Every report is advisory, not an appraisal.
