Last updated: 2/10/2026

AtriumCMS is a modern, web-based platform designed for homeowners associations (HOAs) and condominium associations. It gives your community a professional online presence with tools for document management, governance tracking, event coordination, and resident communication — all in one place.

Key Features

  • Document Library — Securely store and share governing documents, meeting minutes, financial reports, and more. Residents access what they need, when they need it.
  • Community Portal — A branded resident portal where members can view announcements, upcoming events, board information, and community resources.
  • Board & Governance — Track board positions, committee assignments, member terms, and certifications. Maintain a clear organizational structure.
  • Content Management — Publish posts, notices, events, and resources with visibility controls that determine who sees what.
  • Member Management — Invite residents, assign roles, and manage user access across your community.

How It Works

Each community gets its own portal — a dedicated website branded with your association's name, logo, and colors. Administrators manage content through an admin dashboard, while residents access their portal to stay informed and engaged.

For Residents

Your community portal is your go-to source for association information. Log in to:

  • Browse and download official documents
  • View upcoming events and community news
  • Find contact information for board members and management
  • Stay up to date with notices and announcements

For Administrators

The admin dashboard gives you full control over your community's portal:

  • Upload and organize documents into categories and folders
  • Create and schedule events, posts, and notices
  • Manage users, roles, and invitations
  • Configure your site's branding, SEO, and homepage
  • Track board positions, terms, and certifications
