Threshold BuildingInspections
Special inspector services for threshold buildings under Florida law. Certified structural inspections during construction for buildings over 3 stories or 50 feet in height.
What is a Threshold Building?
Under Florida law, a “threshold building” is any building that exceeds certain size or occupancy thresholds that require special structural inspections during construction by a certified special inspector.
These requirements ensure that large or high-occupancy buildings are constructed in accordance with approved plans and specifications, with independent verification by a qualified engineer or architect.
The special inspector works independently of the contractor and reports directly to the building official, providing an additional layer of quality assurance for critical structural elements.
Threshold Building Criteria
A building qualifies as a threshold building if it meets ANY of the following:
- More than 3 stories in height
- Greater than 50 feet in height
- Assembly occupancy over 5,000 sq. ft. with occupant load exceeding 500
- New construction, repairs, or restoration modifying structural systems

Florida law requires specific qualifications for special inspectors of threshold buildings under FAC 61G15-35.

Frequently Asked Questions
What is a threshold building in Florida?
Under Florida law, a threshold building is any building that is more than 3 stories or 50 feet in height, or has an assembly occupancy classification that exceeds 5,000 square feet floor area and is designed to be occupied by more than 500 people. These buildings require a licensed engineer or architect to serve as the special inspector during construction.
What does a threshold inspector do?
A threshold inspector is a licensed PE or architect who performs on-site inspections of structural components during construction of threshold buildings. They verify that the work is being performed in accordance with the approved structural plans and issue reports to the building department throughout the project.
Is a threshold inspection the same as a building inspection?
No. A threshold inspection is a specialized engineering inspection of structural systems performed by a licensed PE during construction of tall or complex buildings. It is separate from and in addition to standard building department inspections, and must be conducted by a qualified structural engineer.
Does AGEngineering provide threshold inspection services in Miami?
Yes. AGEngineering PE provides threshold building inspection and special inspector services for construction projects throughout Miami-Dade and Broward County. Our licensed PE provides all required inspection reports and coordinates directly with the building department.
