Miami-Dade Senate Bill 4-D Milestone Inspection Permits in 2026





Introduction to Senate Bill 4-D Milestone Inspections

Senate Bill 4-D milestone inspections represent the most consequential building safety reform in Florida history, enacted in response to the 2021 Champlain Towers South partial collapse in Surfside. The legislation codified mandatory periodic structural inspections of condominium and cooperative buildings three stories or more in height, with permit-driven repair work flowing from inspection findings. Miami-Dade County, with the largest concentration of high-rise oceanfront condominium inventory in Florida, processes the highest volume of milestone inspection-driven repair permits in the state. Every building subject to the milestone inspection requirement must complete the inspection on schedule, and every repair scope identified by the inspection must proceed under a building permit issued by the local authority having jurisdiction.





The Champlain Towers South Collapse and Legislative Response

On June 24, 2021, a portion of the 12-story Champlain Towers South condominium in Surfside collapsed without warning, resulting in 98 deaths and prompting one of the most significant structural failure investigations in modern American history. Subsequent investigation by the National Institute of Standards and Technology has identified contributing factors including long-term water intrusion, reinforcement corrosion, foundation settlement, and inadequate ongoing maintenance documentation. The Florida Legislature responded in May 2022 with Senate Bill 4-D, codified at Florida Statutes Section 553.899, establishing the mandatory milestone inspection regime for buildings three stories or more in height with subsequent technical amendments through 2023 and 2024.





Florida Statutes Section 553.899 Framework

Florida Statutes Section 553.899 requires milestone inspections of condominium and cooperative buildings three stories or more in height. The initial milestone inspection must be completed at 30 years from the issuance of the Certificate of Occupancy, or 25 years for buildings within three miles of the coastline as measured from the high water line, which captures virtually all condominium inventory in coastal Miami-Dade municipalities. Subsequent milestone inspections must be completed every 10 years thereafter. The inspection must be performed by a Florida-licensed engineer or architect, with a written report submitted to the local building official and the condominium association board.





Phase 1 Milestone Inspection: Visual Assessment

Phase 1 milestone inspection consists of visual assessment of the building's structural elements by a Florida-licensed engineer or architect. Inspection scope includes load-bearing walls, columns, beams, slabs, foundations, balconies, exterior building envelope, and other primary structural elements. The Phase 1 inspector documents observed conditions including cracking, spalling, corrosion staining, deflection, displacement, water intrusion evidence, and any indicators of structural distress. The Phase 1 report concludes with one of three findings: no structural deterioration observed, substantial structural deterioration observed requiring Phase 2 evaluation, or uncertainty regarding observed conditions requiring further investigation.





Phase 2 Milestone Inspection: Destructive and Detailed Testing

Phase 2 milestone inspection is triggered when Phase 1 identifies structural deterioration or where Phase 1 findings are inconclusive. Phase 2 involves more detailed investigation including destructive testing of suspected damaged areas, concrete core sampling for compressive strength testing, reinforcement exposure for corrosion assessment, ground-penetrating radar for slab condition verification, post-tension cable end inspection, foundation excavation where settlement is suspected, and detailed structural calculation review. The Phase 2 report documents the extent and severity of identified deterioration and recommends specific repair scope, repair sequencing, and any interim safety measures pending repair completion.





The 25-Year vs 30-Year Initial Inspection Threshold

The 25-year initial milestone inspection threshold for buildings within three miles of the coastline applies to substantially all condominium buildings in the coastal municipalities of Miami-Dade County including Miami Beach, Bal Harbour, Surfside, Bay Harbor Islands, Sunny Isles Beach, Aventura, Golden Beach, Key Biscayne, and the eastern portions of Miami, Coconut Grove, and unincorporated coastal Miami-Dade. Buildings more than three miles inland — concentrated in central, western, and southern Miami-Dade — face the 30-year threshold. The distinction reflects the accelerated deterioration of concrete and reinforcement in saltwater-exposed environments, with chloride ion penetration driving reinforcement corrosion at substantially higher rates in coastal buildings.





Subsequent Milestone Inspections and Reporting Cycle

Following the initial milestone inspection, condominium and cooperative buildings subject to Section 553.899 must complete subsequent milestone inspections every 10 years. The 10-year subsequent inspection cycle continues for the operational life of the building. Inspection reports must be submitted to the local building official having jurisdiction and to the condominium association board of directors, with the association required to make the report available to all unit owners. The local building official may require remedial action where the inspection identifies conditions warranting repair, and the association board carries fiduciary responsibility for ensuring compliance with the inspection findings.





Permitting Repair Scope Identified by Milestone Inspections

Repair scope identified by milestone inspections drives a volume of permitting activity in coastal Miami-Dade municipalities. Common repair categories include balcony rehabilitation involving concrete spalling restoration and post-tension cable repair, balcony railing replacement with current Notice of Acceptance-compliant systems, concrete restoration of structural columns, beams, and slabs, waterproofing and joint sealant replacement, foundation underpinning where settlement is identified, and structural reinforcement supplementation where original design is found inadequate. Each repair scope category requires a building permit, signed structural engineering documentation, and coordination with the engineer of record.





Engineer of Record and Condominium Association Coordination

Milestone inspection-driven repair permits require close coordination between the engineer of record performing the Phase 1 and Phase 2 inspections, the condominium association board of directors and association management, the contractors performing the repair work, and the local building official having jurisdiction. The engineer of record typically prepares the repair documents, the condominium association board approves the scope and funding (often requiring special assessments to unit owners), and the contractor pulls the building permit under the primary structural engineering documents. Continuing coordination throughout construction is essential to address conditions discovered during repair that may modify the original scope.





Common Causes of Milestone Inspection Permit Delays

Common causes of milestone inspection-driven repair permit delays in Miami-Dade County include incomplete structural engineering documentation, missing condominium association board approval for repair funding, missing Notice of Acceptance documentation for balcony railing replacement products, inadequate sequencing plan for projects affecting multiple floors of an occupied building, missing tenant notification documentation for occupied units, and missing engineer of record continuing involvement documentation. Permit expediters familiar with Section 553.899 and post-Surfside reform protocols can substantially shorten the review cycle.

The Reserve Study That Prices the Findings

The reserve study prices what the inspection finds, with the structural integrity reserves computed from the building's real condition, the milestone's findings flowing into the funding schedule, and the association's budget reshaped by the engineering the statute now requires it to face. The findings become line items the budget must carry. Connecting them completes the compliance.
