Look up a property and its owner
Start from an address, make sure it's the right parcel, then read the records behind it. What comes back depends on what the county publishes.
Ask
Who owns 500 Howard St in San Francisco, and what did they pay?
Cite the sources, and say what's missing.
What the assistant does
searchfor the address. If more than one property matches, it asks which one you mean.fetchthe property it picked for the full record: owner of record, sales, assessments and sources.get_property_ownershipfor saved ownership research and the people connected to the owner.
For a filtered screen instead of one address, such as office buildings in Oakland held for more than 15 years, it uses search_properties.
What a good answer looks like
- It names the property and parcel it found.
- Every fact has its source and date.
- The owner of record is kept apart from the people behind it. A registered agent isn't the owner.
- An assessed value isn't passed off as a sale price.
- Anything the county doesn't publish is called missing, not zero.
