Retired architect Gene Cravillion hasn’t practiced architecture since August 2022. He suffers from dementia and lives in a North Naples assisted-living facility. Yet more than 400 plans bearing his state-registered architectural seal have been submitted to the Collier County Building Plan Review & Inspection Division since then; he ostensibly wrote letters to the county last November and December affirming his work; and his license was renewed in November for two years. Seemingly fraudulent Cravillion letters were typed on letterhead using his seal — and someone posing as him inspected work on homes and attended a county hearing.
