How often are City records checked?

A scheduled re-check reads each City source again. A change alert needs a read that answered and a comparison with the last one that did. The dashboard shows when each source last answered, and which ones didn't, rather than claiming everything is current.

The limit is the City's publishing schedule, not ours. The City's lookup systems are administrative databases updated on the City's schedule, and a change such as a renewal that just posted or a violation that was just cleared can take a business day or more to appear in the source data itself, and the City's published Certificate of Rental Suitability records can run weeks behind. Our re-check reads what the City has published, so freshness has two parts: how often we check (daily, scheduled) and when the City publishes (outside anyone's control but the City's).

That is also why every result we show carries a full last-checked timestamp instead of implying real-time status. If a result matters for a decision you are making right now, the timestamp tells you exactly how current the underlying read is.

For what happens when a City source fails to respond at all, see the related answer below; a failed lookup is labeled, never silently treated as a pass.
