The hazard file, from the maps that decide the premium.

FEMA's flood layer, the ABAG shaking scenarios, Alquist-Priolo fault zones, the city's storm and sea-level maps, soft-story standing, fire-safety violations on the parcel and the fire department's record around it — one address, every mapped exposure, each from the body that publishes it and none of them blended into a score. Beside them, the EPA's own compliance record for every regulated site on the block, and the federal wetland map read at the address.

The questions it answers

The sections that earn their keep

The underwriting extractEvery COPE-shaped fact the report holds — construction, occupancy, protection, exposure — as one flat CSV or JSON per address, beside every report, built to be keyed into a rating system rather than read.
FEMA flood zoneZone, SFHA standing, panel and effective date — the fields the application actually asks for.
Earthquake scenarios and historyModeled shaking beside the earthquakes that actually happened here, which is what a legend cannot say.
Fire safetyViolations at the parcel and the department's activity nearby, from the department's own record.
Soft storyWhether the building carries the retrofit obligation, and its recorded status.
Electrical and plumbing permitsThe knob-and-tube question, answered from the record: every trade permit on the parcel, with dates — evidence of the rewire and the re-pipe, or the absence of either.
Commercial vacancyWhether nearby taxable storefronts filed as vacant — the city's only systematic count of empty space, in the language of an occupancy question.
Water riskThe city's own storm and sea-level mapping, which covers ground FEMA does not.
The EPA's compliance recordEvery site around the address the agency holds a record for, and how many are out of compliance today, formally acted against, or have paid a penalty — environmental exposure on the block, from the regulator rather than from a vendor's model.
Mapped wetlandsWhether the federal inventory maps a wetland where the address stands, counted apart from what is merely nearby and apart from open water, which is the bay and not a constraint on the parcel.

Every figure names its dataset and date, every report is receipted in an audit log, and nothing is blended into a score — documentation shaped to survive a market-conduct exam, not just to price a risk.

Nothing here needs a compliance read. The report contains no scores, grades or rankings — no safety rating, no school grade, no neighborhood letter. Those are the classic proxies for what the Fair Housing Act protects, and this product refuses them by design: you get counts, comparisons and sources. It names no person, and it is not a consumer report.
