The Complete Guide to Florida Milestone Inspections (2025-2026)

Following the Champlain Towers South collapse in Surfside, Florida, in June 2021, the Florida Legislature enacted Senate Bill 4-D (SB 4-D) in May 2022, creating the mandatory milestone inspection program codified under Florida Statute 553.899. Subsequent legislation, including HB 1021 (2024) and HB 913 (effective July 1, 2025), has refined these requirements further.

For condominium associations, cooperative boards, property managers, and building owners, understanding milestone inspections is essential. These inspections carry legal deadlines, financial implications, and serious consequences for noncompliance. At M2E Consulting Engineers, we have been helping Florida building owners navigate structural inspection requirements since 2005, operating from four offices across the state. This guide covers everything you need to know heading into 2025 and 2026.

What Are Florida Milestone Inspections?

A milestone inspection is a mandatory structural assessment required by Florida law for qualifying condominium and cooperative buildings. Established by SB 4-D and governed by Florida Statute 553.899, its purpose is to ensure that aging residential buildings remain structurally sound and safe for occupancy.

Unlike routine property maintenance reviews, milestone inspections focus specifically on the structural integrity of a building’s major components. They must be performed by a Florida-licensed professional engineer (PE) or a licensed architect, and the results must be reported to both the building’s association and the local building official with jurisdiction.

The milestone inspection program is a statewide requirement, distinguishing it from the localized 40-year recertification programs in Miami-Dade and Broward Counties. While those county-level programs remain in effect, milestone inspections apply to qualifying buildings in every Florida county.

Which Buildings Require a Milestone Inspection?

Under Florida Statute 553.899, a milestone inspection is required for any building that meets all of the following criteria:

• Height: Three or more habitable stories as determined by the Florida Building Code. Following HB 913 (effective July 1, 2025), the law specifies “habitable” stories, meaning floors used exclusively for parking, storage, or mechanical equipment may not count toward the three-story threshold.
• Ownership structure: Subject, in whole or in part, to the condominium form of ownership under Chapter 718 or the cooperative form of ownership under Chapter 719.
• Age: Reached 30 years of age based on the date the original certificate of occupancy was issued. Subsequent milestone inspections are required every 10 years.

The 25-Year Coastal Provision

Under SB 4-D as originally enacted, buildings within three miles of the coastline were required to undergo their initial milestone inspection at 25 years rather than 30. However, HB 1021 (2024) modified this provision so the 25-year requirement is no longer automatically mandatory. Instead, the local enforcement agency may determine that environmental conditions, including proximity to salt water, justify requiring the earlier timeline. Many coastal jurisdictions in South Florida have elected to maintain the 25-year threshold. Building owners should check with their local building department to confirm which timeline applies.

Exemptions

The requirement does not apply to single-family homes, duplexes, triplexes, or four-unit dwellings with three or fewer habitable stories above ground. It also does not apply to buildings that are not organized as condominiums or cooperatives, even if they exceed three stories, though such buildings may still be subject to local recertification requirements.

Timeline and Deadlines

The milestone inspection program established a phased deadline structure to manage the large volume of buildings requiring initial inspections.

If your building’s certificate of occupancy was issued before July 1, 1992, the initial deadline of December 31, 2024 has already passed. Buildings that missed this deadline should arrange for their inspection immediately, as local enforcement agencies can impose fines and penalties for noncompliance.

Notification Process

Local enforcement agencies are responsible for identifying qualifying buildings and sending written notice to the association by certified mail, return receipt requested. Upon receiving this notice, the association must notify all unit owners within 14 days. However, the absence of a notice does not relieve an association of its obligation to comply. Boards and property managers should proactively determine whether their building meets the statutory criteria and schedule inspections accordingly.

The Two-Phase Inspection Process

Florida Statute 553.899 establishes a two-phase inspection process. Every qualifying building must undergo Phase 1. Phase 2 is required only when Phase 1 reveals substantial structural deterioration.

Phase 1: Visual Examination

Phase 1 consists of a comprehensive visual examination of the building’s habitable and nonhabitable areas, focusing on major structural components. The licensed engineer or architect conducts a thorough walkthrough assessing the following elements:

• Foundation systems: Footings, grade beams, pile caps, and foundation walls examined for settlement, cracking, spalling, or displacement.
• Primary structural frames and load-bearing walls: Columns, beams, shear walls, and load-bearing masonry inspected for cracks, deformation, or corrosion staining.
• Floor systems: Concrete slabs, post-tensioned decks, and framing members evaluated for excessive cracking, deflection, exposed reinforcement, or delamination.
• Roof structure and deck: Structural roof framing checked for sagging, ponding, deterioration, or connection failures.
• Exterior walls, balconies, and walkways: Connections of exterior wall systems to the primary structure, plus the condition of balconies, railings, canopies, and other projecting elements, all of which receive particular attention due to weather exposure and safety risk.
• Parking structures: If the building includes an integral parking garage, structural elements including supported slabs, columns, and waterproofing membranes are inspected.

The Phase 1 inspection is qualitative. The engineer or architect makes a professional judgment about whether visible conditions indicate substantial structural deterioration. If no such deterioration is identified, the inspector prepares and seals a Phase 1 report, submits it to the association and local building official, and no further action is required until the next 10-year cycle.

Phase 2: In-Depth Investigation

If Phase 1 reveals substantial structural deterioration, Phase 2 becomes mandatory. This is a more detailed, hands-on investigation that goes beyond visual observation to determine the full extent and severity of problems identified in Phase 1. The engineer or architect may employ:

• Destructive testing: Removal of concrete cover to expose reinforcing steel, extraction of concrete cores for compressive strength testing, and localized demolition to access concealed elements.
• Nondestructive testing: Ground-penetrating radar (GPR), ultrasonic pulse velocity testing, half-cell potential surveys for corrosion evaluation, and infrared thermography for detecting delamination or moisture intrusion.
• Material sampling and laboratory analysis: Chloride ion content testing for salt contamination, carbonation testing, and petrographic analysis.
• Structural load analysis: Engineering calculations to determine whether compromised members can safely carry their required loads.

The statute specifies that when selecting test locations, the inspector must give preference to locations that are the least disruptive and most easily repairable while still being representative of the overall condition. At the conclusion of Phase 2, the report must confirm whether the building is structurally sound and, if deficiencies are found, include a recommended repair program.

Who Can Perform Milestone Inspections?

Florida Statute 553.899 limits milestone inspections to a licensed professional engineer (PE) registered under Chapter 471 or a licensed architect registered under Chapter 481. General contractors, building inspectors, and other construction professionals are not authorized to perform these inspections. Because milestone inspections focus on structural assessment and may involve complex engineering analysis during Phase 2, most buildings engage a PE with specific structural engineering expertise.

Under HB 913, design professionals who bid on performing a milestone inspection must now disclose in writing whether they also intend to bid on repair work arising from the inspection findings. This conflict-of-interest provision ensures inspection objectivity. At M2E Consulting Engineers, we maintain a clear separation between our inspection services and any subsequent repair work to ensure the integrity of our findings.

Reporting Requirements

Upon completion of either Phase 1 or Phase 2, the inspecting engineer or architect must submit a sealed copy of the inspection report, along with a separate summary of material findings and recommendations, to:

1. The condominium or cooperative association (and any non-condo/co-op building owner).
2. The building official of the local government with jurisdiction.

The association must distribute the summary to all unit owners regardless of whether results are favorable. Under HB 913, local enforcement agencies must also report milestone inspection data to the Florida Department of Business and Professional Regulation (DBPR), enabling the state to track compliance statewide.

Cost Factors: What Affects Pricing

The cost of a milestone inspection varies significantly based on several factors. Understanding these variables helps associations budget appropriately and evaluate proposals.

Phase 1 Cost Drivers

• Building size: A three-story building with 20 units requires far less time than a 25-story high-rise with 300 units.
• Building complexity: Parking garages, podium levels, elevated pool decks, extensive balconies, and mixed-use components increase scope.
• Accessibility: Concealed structural members, limited crawl space access, or restricted areas require additional effort.
• Age and condition: Older buildings or those with visible deterioration may require more detailed Phase 1 documentation.
• Coastal location: Salt air and humidity exposure typically increases scrutiny required.

Phase 2 Cost Drivers

Phase 2 costs increase substantially due to testing, laboratory analysis, specialized access equipment (scaffolding, lifts, swing stages), and the engineering time needed to develop a comprehensive repair program. Phase 1 inspections for mid-size buildings typically range from several thousand to the low tens of thousands of dollars. Phase 2, when required, can reach into the tens of thousands or more. The condominium or cooperative association is responsible for all costs attributable to the portions it maintains under its governing documents.

Milestone Inspections vs. 40-Year Recertification

Building owners in Miami-Dade and Broward Counties often ask how these two programs relate. While they share the goal of building safety, they are distinct requirements.

Buildings qualifying for both programs must comply with each independently, though a qualified engineering firm can coordinate scope to address both efficiently. For more information, visit our 40-Year Recertification page.

How to Prepare Your Building for a Milestone Inspection

Proper preparation helps the inspection proceed efficiently and allows the engineering team to document conditions more effectively.

Gather Building Documentation

• Original construction drawings: Structural plans and as-built documents provide essential information about the building’s structural system and design intent.
• Certificate of occupancy: Establishes the building’s age and applicable deadline.
• Previous inspection reports: Prior engineering reports, including 40-year recertification reports, Structural Integrity Reserve Studies (SIRS), or property condition assessments, provide valuable baseline data.
• Repair and maintenance records: Documentation of past structural repairs, waterproofing, or concrete restoration work.
• Known issues log: Any known structural concerns, active leaks, or deterioration reported by owners or maintenance staff.

Facilitate Physical Access

• Unlock all common areas, mechanical rooms, roof access points, parking levels, and utility spaces on inspection day.
• Clear stored items from columns, walls, and areas where the inspector needs to examine structural connections.
• Arrange access to a representative sample of individual units, particularly those where owners have reported cracks or water intrusion.
• Have the on-site maintenance supervisor available to answer questions and facilitate access.

Communicate with Unit Owners

Notify owners well in advance about the inspection schedule, what the inspector will examine, expected duration, and whether access to individual units may be needed. Transparent communication reduces confusion and prevents unnecessary delays.

What Happens If Issues Are Found: Remediation Requirements

If Phase 2 identifies substantial structural deterioration, Florida law imposes specific remediation obligations.

Mandatory Repair Timeline

Under provisions strengthened by HB 913, building owners must commence repairs for structural deficiencies identified in a Phase 2 report within 365 days after receiving the report, unless the local governing body requires a shorter timeline. Local boards of county commissioners must adopt ordinances enforcing this deadline.

Repair Process

1. Review the Phase 2 report: The association should review the engineer’s recommended repair program with its legal counsel and board.
2. Engage an engineering firm for repair design: Detailed repair specifications and construction drawings must be developed by a licensed PE to solicit competitive contractor bids. Our forensic engineering team regularly assists associations with this process.
3. Obtain permits and select a contractor: Structural repairs require building permits, and competitive bidding ensures fair pricing.
4. Engineering oversight and final documentation: The design engineer provides periodic construction inspections and a final report confirming deficiencies have been addressed.

Penalties for Noncompliance

Failure to comply with milestone inspection requirements can result in daily fines exceeding $500 per day, code compliance referrals leading to special magistrate hearings and liens, referral to the Construction Board of Adjustment and Appeals for an unsafe building case (potentially resulting in a vacate order), and reporting to the state Division of Condominiums for noncompliance. The financial and legal risks far outweigh the cost of the inspection itself.

Coordinating Milestone Inspections with SIRS

The same legislation that created milestone inspections also established the Structural Integrity Reserve Study (SIRS) requirement. Associations required to complete a milestone inspection on or before December 31, 2026 may complete their SIRS simultaneously, which can be cost-effective since the engineer is already on-site evaluating structural components. However, under no circumstances may the SIRS be completed after December 31, 2026 for associations that existed on or before July 1, 2022.

Frequently Asked Questions

How do I know if my building requires a milestone inspection?

Your building requires one if it has three or more habitable stories, is organized as a condominium (Chapter 718) or cooperative (Chapter 719), and has reached 30 years of age based on its certificate of occupancy date. In jurisdictions that adopted the 25-year coastal threshold, the timeline may be shorter. Contact M2E Consulting Engineers or your local building department for confirmation.

What is the difference between Phase 1 and Phase 2?

Phase 1 is a visual examination of structural components. If no substantial deterioration is found, the process is complete until the next 10-year cycle. Phase 2 is triggered only when Phase 1 identifies substantial structural deterioration and involves detailed destructive and nondestructive testing to fully assess the problems and develop a repair program.

Does every building need a Phase 2 inspection?

No. Phase 2 is required only if Phase 1 reveals substantial structural deterioration. Many well-maintained buildings pass Phase 1 without triggering Phase 2. Buildings with deferred maintenance, significant age, or heavy coastal exposure are more likely to require Phase 2.

Who pays for the milestone inspection?

The condominium or cooperative association is responsible for arranging and paying for all costs associated with the portions of the building the association maintains under its governing documents. Non-condo/co-op owners of building portions share responsibility for their attributed costs.

What happens if our building missed the December 31, 2024 deadline?

Arrange for the inspection immediately. Local enforcement agencies can impose fines, issue code violations, and take escalating enforcement actions. Prompt action demonstrates good faith compliance and minimizes penalties.

Can a milestone inspection be combined with a 40-year recertification?

Yes. For buildings in Miami-Dade and Broward Counties subject to both requirements, a qualified engineering firm can coordinate the scope of work to address both simultaneously, reducing costs and disruption. Learn more about the 40-year recertification process.

How long does a milestone inspection take?

For a typical mid-rise condominium, the Phase 1 on-site visual inspection may take one to several days, with the engineering report following within several weeks. If Phase 2 is required, additional testing and analysis can extend the timeline by several weeks to months depending on scope.

Will the inspection disrupt residents?

Phase 1 causes minimal disruption as it is primarily visual. The inspector may request access to select units. Phase 2 can involve more disruptive activities such as concrete coring and exploratory openings, though the statute requires test locations to be chosen for minimal disruption while remaining representative of the structure.

What is “substantial structural deterioration”?

Florida Statute 553.899 defines it as deterioration that compromises a building component’s structural capacity to an extent that poses a threat to the health, safety, or welfare of occupants. This is a professional engineering judgment. Minor cosmetic cracking or surface wear typically does not meet this threshold.

Is a milestone inspection the same as a SIRS?

No. A milestone inspection evaluates the current structural condition and identifies substantial deterioration. A Structural Integrity Reserve Study is a financial planning tool that estimates remaining useful life and replacement costs of major structural components to ensure adequate reserves. Both are required but serve different purposes.
