Building communication, reimagined

ResiDia was built for condominium and HOA communities that deserve better than fragmented email chains, outdated portals, and apps that feel like an afterthought.

We focus on what boards and residents actually use every day: announcements anyone can post, messaging, events, documents, and a neighbor directory that respects privacy.

Our pricing is transparent and based on the number of units in your community — not on how many people log in. Multi-building portfolios are supported with unit-based billing across all managed buildings.

ResiDia is operated by ResiDia Technologies LLC and serves communities across the United States from our home at residiacommunity.com.
