Miami-Dade is Florida's most populous county and one of the country's largest construction markets — high-rise residential, commercial, and renovation projects all require properly recorded Notices of Commencement. Florida law (Fla. Stat. § 713.13) requires a recorded Notice of Commencement for most direct contracts over $2,500 — recorded with the Miami-Dade County Clerk of the Circuit Court in Miami, and posted on the jobsite before the first inspection.
