Overview
Mason AI offers an AI-powered platform that automates the first-pass review of residential building plans for code compliance. It analyzes plan sets against fire, life safety, architectural, energy, and plumbing codes, drafts likely code comments with links to exact references, and prioritizes failed checks to speed up the initial review. The system acts as an assistant to human plan reviewers rather than replacing them, aiming to cut architectural review time significantly. Its goal is to reduce the time and effort needed for private-sector code reviews, helping teams handle rising demand and workforce pressure.
