Connecting Interactive Floor Plans to a Live Availability Feed
Connecting an interactive floor plan to live availability has five stages: identify the true source, map its identifiers to the plan, choose a refresh model, define what the plan shows when the feed fails, and monitor it. Stage four is the one teams skip and the one that causes real damage. A plan that silently displays yesterday's status during an outage is worse than one that says status is temporarily unavailable, because only the second is honest with the prospect.
Live availability is the feature that makes an interactive plan a leasing tool rather than a brochure. It is also the feature most likely to quietly break.
This is the sequence we follow on interactive floor plan integrations.
| Stage | Decision made | Artifact produced |
|---|---|---|
| Stage 1: identify the true source | Which system genuinely knows what is available right now | A named system, a named internal owner, and access credentials or an export path |
| Stage 2: map identifiers | How a unit in the feed corresponds to a boundary on the plan | A mapping table, one row per selectable unit, feed identifier to plan identifier, complete with no unmatched rows on either side |
| Stage 3: choose a refresh model | How current the display has to be, against what the source can support | A stated refresh interval, published on the plan itself |
| Stage 4: define failure behavior | What the plan displays when the feed is unreachable or returns nonsense | A written failure specification covering three cases: feed unreachable, feed stale beyond the refresh interval, and feed returning implausible data such as every unit available |
| Stage 5: monitor it | Who finds out first when the feed stops, you or a prospect | An alert to a named person on feed failure or on data age exceeding the threshold |
Stage 1: identify the true source
Decision: which system genuinely knows what is available right now.
Artifact: a named system, a named internal owner, and access credentials or an export path.
The candidate is usually a property management or membership platform. Sometimes the honest answer is a person and a spreadsheet, and that is worth establishing before anything is built, because it changes the recommendation to a plan without live status.
Stage 2: map identifiers
Decision: how a unit in the feed corresponds to a boundary on the plan.
Artifact: a mapping table, one row per selectable unit, feed identifier to plan identifier, complete with no unmatched rows on either side.
Unmatched rows are the failure to catch here. A unit in the feed with no plan boundary is invisible. A boundary with no feed row shows no status forever, and nobody notices until a prospect asks about it.
Stage 3: choose a refresh model
Decision: how current the display has to be, against what the source can support.
Artifact: a stated refresh interval, published on the plan itself.
Real time is rarely necessary. Multifamily and commercial inventory moves slowly enough that a daily or hourly refresh is honest and far more robust. Coworking moves faster and justifies a shorter interval. Telling the prospect how current the data is costs nothing and sets the right expectation.
Stage 4: define failure behavior
Decision: what the plan displays when the feed is unreachable or returns nonsense.
Artifact: a written failure specification covering three cases: feed unreachable, feed stale beyond the refresh interval, and feed returning implausible data such as every unit available.
The default in most builds is to keep showing the last successful data indefinitely, which turns a technical outage into a leasing incident. The correct behavior is to show status as unavailable once data passes an age threshold, keep the plan itself fully usable, and alert the owner.
If nobody has defined failure behavior on your existing plan, ask us to check it. It is a short review and it is the cheapest correction on this page.
Stage 5: monitor it
Decision: who finds out first when the feed stops, you or a prospect.
Artifact: an alert to a named person on feed failure or on data age exceeding the threshold.
Without monitoring, the discovery mechanism is a leasing agent being contradicted in front of a prospect. That is a bad detector and an expensive one.
The build without a feed is a legitimate build
If stages one through five cannot be completed, the right product is a plan that shows units by type, layout and attributes with availability handled in the conversation. It is not a lesser deliverable. It is the version that stays true, and it can be upgraded later once a real feed exists.
