What Is a Threshold Inspection?
A threshold inspection is Florida's mandatory structural inspection program for certain high-risk buildings — created after the Surfside condo collapse. It requires a licensed special inspector (a Florida PE or architect) to inspect the structural work during construction and to perform milestone inspections of aging condos. Threshold buildings are generally those over 3 stories or 50 feet, or with assembly occupancies over 5,000 sq ft.

What triggers it
Florida Statute defines threshold buildings by height, area, and occupancy — the classic trigger is any building over three stories or 50 feet in height. The building official can also designate structures with unusual configurations. If your project is a threshold building, the threshold inspector must be engaged before construction starts, and the inspection plan is part of the permit documents.
What the inspector does
During construction, the threshold inspector verifies reinforcing steel, concrete placement, structural masonry, and connections per the approved plans — above and beyond the standard special inspections. For existing condos, milestone inspections at 25-30 years (depending on distance from the coast) assess structural integrity, with a second phase of destructive testing if problems are found. Condo associations must now fund reserves for these repairs.
Cost and scheduling impact
Threshold inspection during construction typically adds $15,000-$75,000+ to project cost depending on size, and the inspector's hold-points must be built into the construction schedule. For condo associations, milestone inspections run $10,000-$30,000+ for phase one. Florida developers and associations should engage the threshold inspector at design development — late engagement is the main source of schedule pain.
The bottom line
Florida threshold inspection = mandatory PE/architect inspection for buildings over 3 stories/50 ft, during construction and at condo milestones. Engage the inspector early and budget $15,000-$75,000+.
