What problem does it solve?
City building departments face overwhelming ADU permit submission volumes and understaffed plan review teams, leading to slow turnaround times and inconsistent compliance checks for residential accessory dwelling unit projects, with first-time rejection rates exceeding 90% for many California jurisdictions.
Core Features & Use Cases
- Automated Sheet-by-Sheet Plan Review: Reviews ADU plan sets against California state ADU law (Government Code § 66310-66342) and city-specific municipal codes, checking for missing signatures, incorrect code citations, incomplete forms, and code compliance gaps.
- Draft Corrections Letter Generation: Produces a formatted, code-cited corrections letter for non-compliant submissions, with clear flags for items requiring human verification.
- Use Case: Reduces first-pass plan review time for city staff from hours to minutes, freeing up plan checkers to focus on complex engineering and design reviews.
