Miami Condo Special Assessments: The SB 4-D Reality in 2026

The Champlain Towers South collapse in Surfside on June 24, 2021 killed 98 people and permanently changed Florida condo law. Senate Bill 4-D, signed May 26, 2022, required every condo building 3 stories or taller to fully fund structural reserves by December 31, 2024. Buildings that had deferred maintenance for decades suddenly had to raise tens to hundreds of thousands per unit. If you are buying a Miami condo in 2026, you are buying into this post-SB 4-D market. Understanding it determines whether you avoid a six-figure surprise.

What SB 4-D Actually Requires

Three pillars. First, every condo building 3+ stories must get a Structural Integrity Reserve Study (SIRS) by year 30 of the building's life, updated every 10 years. Second, the SIRS must cover 10 major structural components: roof, load-bearing walls, floor, foundation, fireproofing, plumbing, electrical, waterproofing, windows, and any deferred maintenance over $10,000. Third, condo associations must fully fund reserves for these components. Boards can no longer vote to waive or reduce reserve funding as they did before 2022.

Typical Assessment Ranges by Building Age

Buildings 2023+: near zero assessment risk in first 30 years. Built to current code, reserves built in from day one. Buildings 2000-2022: $5K to $50K per unit typical, covering early waterproofing, roofing, and system upgrades. Buildings 1985-1999: $50K to $150K per unit common, covering concrete restoration, plumbing replacement, and facade work. Buildings 1970-1984: $150K to $400K+ per unit possible, especially beachfront buildings with salt exposure. I have clients who received $280K per-unit assessments on buildings they purchased 3 years ago.

The Special Assessment Disclosure Rule

Florida Statute 718.503 requires sellers to disclose any pending special assessment in the condo addendum to the purchase contract. If the seller knows about an upcoming assessment and fails to disclose, you have a cause of action. If the assessment is announced after your contract but before closing, you typically have the right to cancel or demand seller credit. My rule: never go firm on a condo contract until I have reviewed the last 36 months of HOA meeting minutes for assessment discussions.

How to Negotiate Around a Pending Assessment

If the seller discloses a $150K pending assessment, your options: (1) demand seller credit the full $150K at closing, (2) reduce purchase price by $150K, (3) walk away. The first two are more common. Never absorb a pending assessment silently - it is free money the seller owes you. I have negotiated 100% seller assumption of pending assessments on every transaction where one existed. Sellers know the next buyer will demand the same thing.

Which Miami Buildings Are Safe in 2026

Low-risk: any building delivered 2023 or later (including Aston Martin Residences, 57 Ocean, and all currently delivering pre-construction). Moderate-risk: Class A+ buildings 2010-2022 with verified SIRS compliance and 85%+ reserve funding (Brickell Flatiron, Aria Reserve, Paramount Miami). Higher-risk: beachfront buildings 1970-2000 that were already underfunded, including many in Surfside, Bal Harbour, and North Miami Beach. Always pull the SIRS before writing an offer on anything pre-2010.

Reserve Funding Status Classifications

Based on SIRS reports I've reviewed in the last 90 days: fully funded (85%+ of required reserves): roughly 40% of Miami buildings. Partially funded (50% to 85%): about 35%. Underfunded (below 50%): about 25%. The underfunded group is where the $100K+ assessments live. Pulling the reserve study takes 48 hours. Skipping this step has cost Miami buyers tens of millions in post-closing assessments.

"SB 4-D isn't a bug. It's a feature. The law forces the market to price in real maintenance costs. Buildings that were hiding deferred maintenance are now being revealed. Buildings that were responsibly funded are now properly rewarded."

If you are targeting a specific building, send me the address and I will pull the SIRS, reserve funding status, and any pending or recent assessments within 48 hours.

The December 31, 2026 Deadline: Buildings Still in Process

Florida law allowed buildings whose milestone inspection was due by December 31, 2026 to complete their Structural Integrity Reserve Study simultaneously with that inspection. The combined process must finish no later than December 31, 2026. As of May 2026, a significant share of buildings in this cohort, primarily towers built between 1994 and 1996, are still mid-process. Their engineering reports are not final and their reserve funding plans are not locked.

For buyers closing on a resale unit in one of these buildings during Q3 or Q4 2026, that timing creates real uncertainty. The assessment amount could change between contract signing and closing if the SIRS report comes in higher than the board estimated. My protocol in this situation: request a written board certification of the expected assessment range before going firm on price. If the board will not certify, price in at least a 15% buffer above the disclosed estimate, or push closing to January 2027 when the final number is known.

Buildings that completed their SIRS early, by mid-2024, have already absorbed that uncertainty. Their reserve funding schedule is public record. Those are the resale targets I prefer for clients who want full visibility before closing. For a step-by-step process on what to verify before closing, see the Miami pre-construction buying process guide and the guide on evaluating building financial health.

Phase 1 vs Phase 2 Milestone Inspections: The Detail Most Buyers Miss

The milestone inspection is not a single event. It has two phases, and Phase 2 is not automatic. Phase 1 is a visual evaluation of the building's structural components by a licensed Florida engineer or architect. It covers balconies, columns, load-bearing walls, the roof deck, and the foundation. Cost for a mid-size Miami building typically runs $8,000 to $25,000. If Phase 1 finds no signs of substantial structural deterioration, the process ends there.

Phase 2 is triggered only when Phase 1 identifies substantial deterioration. It requires invasive testing: concrete core samples, laboratory analysis, corrosion mapping, and detailed engineering modeling. Phase 2 costs for a beachfront 1980s building can run $60,000 to $200,000 or more in engineering fees alone, before any repair costs. After the Phase 2 report is delivered, the association has 365 days to commence repairs. That clock is live on buildings that received Phase 2 reports in late 2024 or early 2025.

When I evaluate a building for a buyer, I always ask: Has Phase 1 been completed? If so, was Phase 2 triggered? A building currently in Phase 2 is in a different risk category than one where Phase 1 came back clean. The local building department holds copies of all completed milestone inspection reports, and any licensed agent can request them. Ask before you write an offer.

The May 2026 Assessment Landscape: Three Categories of Miami Buildings

From the transactions I am closing right now, Miami resale buildings fall into three distinct categories in terms of assessment exposure, and the category matters as much as the price per square foot.

Category 1: Front-loaders. These buildings assessed between 2022 and 2024, raised the money, completed the work, and are now reserve-flush. Class A towers in Brickell built 2000-2015 that were well-managed mostly fall here. Buyers in these buildings have the clearest financial picture, though HOA fees are higher than they were pre-SB 4-D. According to data from the Miami Association of Realtors, Q1 2026, these buildings command a 6-8% price premium over comparable inventory in buildings that have not yet resolved their assessment exposure.

Category 2: Mid-assessment. Buildings in this group are currently billing. The total has been voted, the schedule is set, and owners pay in installments. Typical 1980s-1995 beachfront buildings in Surfside, Bal Harbour, and North Miami Beach fall here, with per-unit totals between $30,000 and $100,000 per unit and in some cases exceeding $100,000 for combined waterproofing, concrete restoration, and roof replacement. Buyers in mid-assessment buildings can negotiate seller credit for the remaining unpaid balance. According to reserve specialists I work with in Miami-Dade, nearly half of all buildings in this cohort are still in the billing phase as of Q2 2026.

Category 3: Pre-assessment. These buildings have completed their SIRS, know what they need to fund, but have not yet voted an assessment or raised HOA fees to cover it. This is the highest-risk category for buyers, because the number exists on paper inside the SIRS but is not yet public in the way a voted assessment is. Since January 1, 2025, boards can no longer vote to waive or reduce reserve funding for the structural components covered by the SIRS. The assessment is coming. The question is timing and amount. For buyers, the only safe move is to pull the SIRS, calculate the funding gap yourself, and price that into your offer. A licensed CPA or reserve specialist can turn around that analysis in 48 hours. See the Miami pre-construction buyer guide and true cost guide for how I factor this into client recommendations.
