Inspiration

Special assessments often catch property owners off guard—large, unexpected fees with little transparency or legal recourse. As a condo owner myself, I’ve been affected—and continue to be impacted—by questionable special assessments resulting in substantial additional monthly payments. I found it difficult to understand these charges, know my rights, or connect with others in similar situations. That frustration sparked CondoShield—an AI-powered online platform accessible on the web with seamless, interactive support on mobile browsers that empowers owners to understand, track, and challenge special assessments with confidence.

  • 💬 Ask legal questions to an AI system, based on your selected region

  • 📊 Track all assessments, disputes, and key deadlines in a personal dashboard
  • 🏘️ Collaborate with a community forum of condo owners
  • 💡 View cost-saving suggestions to reduce future assessments
