Name the exact source
For a building rule, record “Resident handbook, page 6, checked April 2: reserve the lift before moving furniture.” Store the handbook where the household can find it. If you have only heard the rule from a neighbor, identify it as a report to verify. If the record is a web page, use its title and a meaningful section as well as the address. If it is a conversation, give the context and say that the information was reported.
Separate evidence from your conclusion
Write the short source statement, then the action you infer. “Handbook says reserve the lift for large furniture” supports a task to ask whether a tall bookcase qualifies. It does not establish that a booking was made. This distinction is useful when a second adult or an assistant reads the record later.
Know what would trigger a new check
Change of season, a revised handbook or a new building manager may make the note stale. Add a review trigger when the fact matters to a future trip. When checked, record the new source or date. Do not change the observation date just because someone tidied the wording.
