CrossBeam tackles California's ADU permit crisis. 429,000+ permits issued since 2018, 90%+ sent back for corrections — each cycle costing weeks and thousands of dollars. Upload your corrections letter and construction plans. CrossBeam reads blueprints using vision, interprets every correction with code citations, cross-references state and city law via live web research, and drafts a response package ready for your engineer to sign. Built on the Claude Agents SDK with 13 custom skills covering state ADU law, city-level research, blueprint extraction, and corrections interpretation — all running concurrently.
