If you own an investment condo in Miami, or you are considering buying one, there is a law reshaping the financial picture of older buildings across the county, and the numbers involved are not small. Following the 2021 Champlain Towers South collapse in Surfside, Florida passed Senate Bill 4-D, creating mandatory structural inspections and reserve funding requirements for condominium buildings statewide. By 2026, both requirements are fully in effect, and buildings across Miami-Dade are issuing special assessments that in some cases exceed $100,000 per unit.
Whether you already own a rental condo or are evaluating a new purchase, understanding this law is essential to protecting your investment.
Key Takeaways
Any condo or co-op building three stories or taller must complete a milestone structural inspection at 30 years of age, or 25 years for buildings within three miles of the coast.
As of January 1, 2026, associations can no longer waive reserve funding for structural components like roofs, load-bearing walls, and waterproofing.
Buildings that miss inspection deadlines face escalating fines, potential vacate orders, and personal liability exposure for board members.
Non-compliant buildings risk being placed on Fannie Mae's unavailable list, which blocks conventional financing for unit sales.
What SB-4D Actually Requires
The law creates two separate but overlapping obligations for any residential condominium or cooperative building three or more habitable stories tall. The first is the milestone inspection, a structural evaluation performed by a licensed engineer or architect. Buildings must complete their first Phase 1 visual inspection at 30 years from their certificate of occupancy date, or 25 years if the building sits within three miles of the coastline, which covers a significant share of Miami-Dade's condo stock. If that inspection finds evidence of structural distress, a more detailed and more expensive Phase 2 inspection follows.
The second obligation is the Structural Integrity Reserve Study, commonly called a SIRS, which assesses nine specific structural components, including the roof, load-bearing walls, plumbing, electrical systems, and waterproofing, and determines how much the association should be setting aside in reserves for each one.
The End of Reserve Waivers
This is where the real financial impact lands for owners. Before this law, Florida condo associations could vote to waive or reduce their reserve contributions, which many buildings did for years to keep monthly fees artificially low. That option is gone for structural components. The ban took effect for budgets adopted after December 31, 2024, and full reserve funding was required to begin by January 1, 2026.
Associations can still waive reserves for non-structural items like landscaping or pool equipment with a majority vote, but the components that actually drive major repair costs, roofing, structural elements, waterproofing, are now locked into mandatory funding. For buildings that spent decades underfunding these reserves, the sudden requirement to catch up has translated directly into special assessments, sometimes ranging from $30,000 to well over $100,000 per unit at older coastal buildings.
What This Means If You Own a Rental Condo
If your investment property sits in a building 25 years or older, this law directly affects your holding costs, and potentially your cash flow, in ways that go beyond a typical rental property. A special assessment on a unit you rent out does not generate additional rental income to offset it, which means it comes straight out of your investment returns. Before assuming a property's monthly costs are stable, it is worth confirming your building's milestone inspection status and reserve funding level directly with the association.
If you are considering purchasing an additional investment condo in Miami, requesting the building's most recent milestone inspection report and SIRS before making an offer is now standard due diligence. A seller is required to provide a copy of the inspection summary and the association's most recent SIRS, or a written statement that one has not been completed, before closing. If an association cannot produce these documents, that is worth treating as a serious red flag rather than a minor paperwork gap.
What Happens If a Building Falls Behind
The consequences of missing these deadlines escalate quickly, and they affect every owner in the building, not just the association. Buildings that fail to complete required repairs identified in a Phase 2 inspection within 365 days can be referred for an unsafe building determination, which can ultimately result in a vacate order forcing residents out entirely. Board members who willfully fail to arrange required inspections can face personal liability for breach of fiduciary duty.
Beyond the immediate safety concerns, non-compliant buildings risk being added to Fannie Mae's unavailable list, which currently includes roughly 5,000 condos nationwide, with nearly 700 concentrated across Miami-Dade, Broward, and Palm Beach counties. Once a building lands on this list, buyers in that building generally cannot obtain conventional financing, which can significantly depress resale values and make units harder to sell, a real concern for any investor thinking about their exit strategy.
Protecting Your Investment Going Forward
For owners of investment condos, staying informed about your building's compliance status is no longer optional due diligence, it is an ongoing part of managing the property's financial risk. A few practical steps worth taking:
Request your building's most recent SIRS and milestone inspection status directly from the association if you have not seen these documents recently.
Ask how fully funded your building's structural reserves currently are. A building funded at 30 percent carries considerably more risk of a large special assessment than one funded at 80 percent or higher.
Factor potential assessment exposure into your rental pricing and cash flow projections, particularly for buildings approaching their 25 or 30-year milestone.

FAQ
Does this law apply to single-family rental homes?
No. SB-4D applies specifically to condominium and cooperative buildings that are three or more habitable stories tall. Single-family homes, duplexes, and smaller buildings are not subject to these requirements.
Can I negotiate around a pending special assessment when buying a condo?
Yes, this is commonly handled in Miami resale transactions either by having the seller pay the outstanding balance before closing or by negotiating a price reduction equal to the assessment amount.
How do I find out if my building has completed its milestone inspection?
Associations are required to distribute the inspector-prepared summary to unit owners within 45 days of receiving it, and to post it on the association's website if one is required. You can also request this directly from your board or management company.
What happens if my building is on Fannie Mae's unavailable list?
Buyers in that building generally cannot obtain conventional mortgage financing, which can make units harder to sell and may depress resale values until the building achieves compliance.
Staying Ahead of a Serious Financial Risk
This law exists because of a tragedy, but the financial reality for Miami condo investors now is that building-level compliance directly affects property value, financing availability, and your bottom line. Owners who stay informed and ask the right questions before problems escalate are in a far stronger position than those who find out about a special assessment after it has already been approved.
