Median owner-cost anchor (Zillow-style benchmark)
$3,265,535
Figure reflects a third-party median home value commonly used as a market anchor. It does not describe your
individual home condition, replacement cost, or insurability.
Residential structure risk context index
60/ 100 — Moderate watch band
Lower elevation band → higher sensitivity to pluvial / drainage stress in some climates.
Higher median context often correlates with larger conditioned envelopes and specialty systems—maintenance checklists tend to be longer.
County anchor (Marin County) is used only to keep cohort narratives locally grounded—not as a regulatory signal.
The line is a deterministic visualization derived from this page's stable seed plus the index above. It
does not ingest live sensor feeds, claims feeds, or municipal inspection databases.
