We get it — WhatsApp is already on everyone's phone. Creating a group takes 30 seconds. It feels like the obvious choice for building communication. Until it isn't.
Where WhatsApp breaks down
The noise problem
A water shutoff notice posted at 9am gets buried under 47 messages about parking by noon. Important information disappears in real-time chat — it's designed for conversation, not announcements.
The privacy problem
When you add tenants to a group, everyone sees everyone's phone number. You're essentially sharing personal data of all residents with each other. In the EU, this raises GDPR concerns.
The search problem
"When was the last boiler service?" Good luck finding that in a 6-month-old chat thread with 2,000 messages. Critical information is unsearchable.
The boundary problem
Tenants message you at 11pm about non-emergencies. Your personal WhatsApp becomes your work WhatsApp. There's no separation between your professional role and your private life.
The tracking problem
Did everyone read the notice? You have no idea. Did the maintenance request get handled? You'd have to scroll back through the chat to find out.

The switch is easier than you think
You don't need to migrate anything. Create a building workspace, invite tenants with a link, post your first announcement, and let the old WhatsApp group fade naturally. Most managers report full adoption within two weeks.
