Instead of re-keying zoning logic, life-safety sheets, and permit narratives across separate tools, architects screen eligibility, check existing-building code, and prepare discretionary and site-permit packages with Otto on one connected record — while keeping licensure and sign-off control. Design intake, conversion-specific cost, construction tracking, and digital twin handover are on the roadmap. Works with Revit via Autodesk Construction Cloud, or through Open, non-proprietary file formats for building design data — an alternative to being locked into one software vendor. when you do not run Revit. See the roadmap.
About us
What is plinth.OS?
plinth.OS is the permitting platform for existing and non-standard buildings — built for architects under 50 staff doing renovation, addition, and conversion work.
Eligibility screening
Check whether a building qualifies for adaptive reuse, office-to-residential conversion, or related pathways before you invest design hours.
Existing-building compliance
Code and ordinance checks tuned to renovation, addition, and conversion scopes — not greenfield new construction alone.
Otto for discretionary prep
Human-reviewed discretionary and site-permit prep on the same record. Licensed professionals review and sign before anything is filed.
What's next
As the permitting core proves out, we're extending the same record into design intake, conversion-specific cost, construction tracking, and digital twin handover — see the roadmap.

Amir Duke
Founder & CEO
Amir Duke is the founder and CEO of plinth.OS. After recognizing that permitting software is built for repeatable, new-construction work — while adaptive reuse, additions, and conversions run on a different, less standardized rule set — he built plinth.OS to give architects eligibility screening, existing-building code compliance, and Otto for human-reviewed discretionary and site-permit prep on one connected record, without asking them to give up licensure or sign-off control.
