Track a location separately when consistency across many scenes becomes harder than simply remembering it.
A place can carry story information
A house has rooms, history and constraints. A city has districts and travel time. A fictional station may have rules, factions and recurring scenes. Repeating that information in notes attached to individual chapters creates drift.
Locations help answer “where does this happen?”
When scenes can point back to the same place, the location becomes another way to navigate and inspect the story.

Not every place deserves a card
If a café appears once, write “café” and move on. Structured location data is useful only when the place becomes important enough that consistency and reuse matter.
The same progressive-complexity rule applies
Do not build a world database before writing. Promote a place into a structured entity when the manuscript earns the complexity.
