Post-Surfside Miami condo diligence.

On June 24, 2021, the 12-story Champlain Towers South condominium in Surfside (Miami-Dade) partially collapsed, killing 98 residents. Investigation pointed to long-deferred structural maintenance, inadequate reserves, and a board culture that prioritized low monthly assessments over capital reinvestment.

Florida’s legislative response was Senate Bill 4-D (SB-4D), signed by Governor DeSantis May 26, 2022, with key provisions effective immediately and others phased in through 2024. The bill creates three structural changes:

1. Mandatory milestone inspections at 30-year intervals (25 years if within 3 miles of the coastline) for buildings 3+ stories
2. Structural Integrity Reserve Studies (SIRS) — periodic engineering review of structural reserves
3. Elimination of reserve waiver votes for items on the SIRS list — previously, condo associations could vote to waive funding their structural reserves; that’s no longer permitted

These changes apply to all Florida condominium and cooperative associations, not just Miami-Dade. But Miami’s older condo inventory (1960s–1980s buildings) carries the most concentrated exposure, particularly along the South Beach oceanfront and the Brickell waterfront.

The requirement

Buildings 3 stories or taller must complete a milestone inspection by their 30-year anniversary, or 25-year anniversary if located within 3 miles of the coastline. Inspections must be repeated at 10-year intervals thereafter.

The inspection has two phases:

• Phase 1: Visual assessment by a licensed FL engineer or architect. Identifies any signs of substantial structural deterioration.
• Phase 2: Required only if Phase 1 identifies substantial structural deterioration. More invasive testing — concrete sampling, rebar exposure, structural load analysis.

The report

The inspection report becomes part of the association’s official record. It must be:

• Filed with the local building department
• Made available to current and prospective owners
• Posted in a conspicuous location on the property
• Included in the association’s seller disclosure package

What “substantial structural deterioration” means

The phrase is defined by FL Building Code as conditions that have progressed beyond ordinary wear and tear and threaten the building’s structural integrity if not remediated. Examples:

• Spalling concrete with exposed corroded rebar
• Substantial cracking in load-bearing structural elements
• Evidence of foundation settlement or shifting beyond normal tolerance
• Water intrusion patterns indicating envelope or structural failure

Buildings flagged with substantial deterioration face the most immediate special-assessment exposure — the Phase 2 investigation, the remediation work, and any prophylactic upgrades flowing from the findings.

The requirement

Condominium associations governing buildings 3+ stories must complete a Structural Integrity Reserve Study every 10 years. Started 2024 for previously-built buildings; all new construction includes a SIRS from the start.

The SIRS is performed by a licensed FL engineer or architect and assesses the reserve funding needed for specific structural components:

• Roof systems
• Load-bearing walls and structural frame
• Floor and waterproofing systems
• Plumbing and electrical systems serving the structure
• Windows and exterior doors integrated into the building envelope
• Fire protection systems
• Other items with deferred maintenance costs exceeding $10,000

The funding requirement

The SIRS identifies a 30-year funding plan for each structural component, based on its expected useful life and estimated replacement cost. The board must fund reserves at the SIRS-recommended level — and reserve funding for SIRS items can no longer be waived by owner vote.

The gap between current reserves and SIRS recommendations

This is where the special-assessment exposure concentrates. Many Miami buildings — particularly those that historically waived reserve funding to keep monthly assessments low — face SIRS recommendations several multiples higher than their current reserve balances. The gap has to be closed, often through special assessments against unit-owners.

For HNW buyers, the question is whether the gap has already been closed at the building you’re considering (special assessment already issued, work already underway) or remains pending (special assessment is coming and will affect future owners).

Pre-SB-4D, FL condo associations could vote (by majority of owners) to waive or reduce reserve funding for any category. Many older Miami buildings did this routinely — owners preferred lower monthly assessments, the board didn’t want to fight over it, and reserves stayed chronically underfunded.

SB-4D eliminates the waiver vote for any item on the SIRS list. The board MUST fund SIRS-identified reserves at the recommended level. There’s no override.

The practical effect on monthly assessments

At buildings where reserve waivers were routine, monthly maintenance assessments have risen 25%–100%+ since effective dates. Specific examples reported in 2023-2025:

• Many South Beach 1960s-era oceanfront condos: monthly assessments doubled or tripled following SIRS adoption
• Older Brickell waterfront buildings: substantial monthly increases plus special assessments for catch-up funding
• Smaller boutique buildings (under 50 units): some effectively become uninsurable or non-viable as the reserve funding burden per-unit becomes unsupportable

What this means for buyers

The buyer of a unit at a building that hasn’t yet fully implemented SIRS funding is buying into a building that will see monthly costs rise, possibly substantially, over the next 1-3 years. Build this into your carrying-cost projection.

Special assessments at older Miami buildings have become meaningfully larger in the post-Surfside era. The representative range:

• Modest catch-up: $25K–$100K per unit at buildings where reserves were close to adequate
• Significant gap-closing: $100K–$300K per unit at older South Beach and Brickell buildings with substantial deferred maintenance + new SIRS findings
• Extreme cases: $300K–$1M+ per unit at buildings facing both substantial structural remediation AND insurance market issues

The assessments may be one-time or spread over multiple years. For HNW buyers, the key question is whether the special assessment has been formally adopted (in which case it transfers to the new owner) or is still pending. The diligence answer can shift the deal economics by hundreds of thousands of dollars.

The disclosure regime

FL law requires sellers to disclose adopted special assessments to prospective buyers as part of the standard condo disclosure package. However:

• A special assessment that’s been discussed but not yet formally adopted may not require disclosure
• A SIRS that’s identified substantial reserve gaps but the board hasn’t yet acted on it may not require disclosure either
• Diligence requires going beyond the disclosure package — reviewing recent board minutes, the SIRS itself, and any consulting reports

FL’s broader insurance market crisis interacts with the post-Surfside regulatory environment to produce concentrated stress at older Miami buildings. The dynamics:

• Many insurers have exited FL residential market entirely (HSBC, Farmers, AAA, multiple regional insurers)
• Citizens Property Insurance (the state-backed insurer of last resort) now covers a substantial share of FL residential
• Insurer underwriting has tightened on older buildings — some refuse to write at all for buildings without completed milestone inspections
• Premiums for older oceanfront buildings have run 100-300% increases since 2020
• Some buildings carry windstorm exclusions or substantial wind deductibles that effectively transfer hurricane risk to individual owners

The implication for buyers

An older Miami condo building’s ability to obtain adequate insurance — at supportable premiums — is now part of the diligence question. Some buildings have passed the inflection point where insurance becomes effectively unobtainable; those buildings face a fundamental viability question.

Before signing LOI on any Miami condo built before 2000 (and arguably any built before 2015), request the following from the listing broker / managing agent:

Milestone inspection

• Has the milestone inspection been completed? When?
• Phase 1 report (visual assessment)
• Phase 2 report if applicable (substantial structural deterioration identified)
• Any remediation work scope and completion status
• Cost of completed and ongoing remediation

SIRS

• Most recent SIRS report (should be within last 5 years if recently established)
• Comparison of current reserves to SIRS-recommended funding
• Specific structural components flagged for replacement within next 5-10 years
• Funding plan to close any current gap

Special assessments

• Any adopted special assessments still being collected
• Any pending discussions of new special assessments at recent board meetings
• Engineering or contractor reports that may inform a pending assessment

Financial documents

• Most recent audited financial statements (2-3 years)
• Current budget
• Reserve balances by component category
• Any outstanding association loans (signal of deferred maintenance being financed)

Insurance

• Current policy summary (carrier, premium, deductibles, coverage limits)
• Recent renewal history (premium trajectory)
• Any coverage exclusions (windstorm, flood, structural)
• Carrier confirmation that the building is in good standing

Building condition expert review

For trophy-tier purchases ($5M+), engaging an independent FL-licensed structural engineer to review the milestone report and SIRS is worth $5K-$15K of consulting fees. They can identify red flags or vindication points the listing materials gloss over.

The post-Surfside regulatory regime hits hardest at:

1960s-1980s South Beach oceanfront

Many of these buildings were converted from rental in the 1980s-1990s with limited capital reserves. The combination of age, oceanfront exposure (salt air corrosion), and historically-waived reserves produces the most concentrated stress.

Older Brickell waterfront

Similar dynamics for Brickell buildings dating from before the modern luxury condo boom (pre-2000 construction). Mix of corroding rebar (urban marine environment) plus historically-low reserves.

Boutique smaller buildings

Buildings under 50 units distribute the reserve and special assessment burden across fewer owners — making the per-unit cost potentially extreme. Some smaller buildings have become effectively non-viable as going-concern condominiums.

What’s less affected

• Newer construction (post-2000) typically has adequate reserves and SIRS-compliant structural design
• Trophy condo buildings (Faena, Edition, One Thousand Museum, etc.) typically have strong reserve postures and modern construction
• Single-family Miami inventory (Coconut Grove, Coral Gables, etc.) isn’t directly affected by the condo regulatory regime
