Contra Costa County
The property was improved after the date of death
When renovations, repairs, additions, or cleanup occurred after death and the estate still needs the earlier value.
The property visible today may be materially different from the property that existed on the historical effective date.
Contra Costa County estates may involve everything from older West County homes and central-county suburbs to hillside, luxury, rural-edge, and Delta-oriented residential properties.
Before-and-after photographs, invoices, permits, contractor records, listings, and family recollections can help distinguish later improvements from the earlier condition.
