The Milestone Inspection Condo Buyer Guide

If you're buying a Florida condo unit in a building three or more stories tall, the milestone inspection report is one of the few documents that can definitively change the math on your purchase. It is a physical assessment of whether the building is structurally deteriorating — the exact failure mode implicated in the 2021 Champlain Towers South collapse in Surfside — and its findings can imply a six-figure repair bill that lands on owners as a special assessment. This guide explains what the inspection is, what triggers it, how it differs from the reserve study that accompanies it, and what a buyer should request and read before closing.

What a milestone inspection is, and what triggers it

A milestone inspection is a structural inspection of a building's primary structural systems, required under Florida law (Fla. Stat. §553.899) and enforced by local building officials. It was created by SB 4-D in the 2022 special session — Florida's emergency legislative response to Surfside — and refined by SB 154 (2023) and HB 913 (2025).

Three conditions determine whether a building is subject to the requirement, and a building has to meet all three:

• Height. The building must be three or more habitable stories tall. Two-story buildings and townhome-style communities generally fall outside the requirement.
• Age. The initial inspection is due by December 31 of the year the building reaches 30 years of age, measured from the certificate-of-occupancy date.
• Coastal proximity. For buildings located within three miles of the coastline, the threshold drops to 25 years. Salt air and humidity accelerate concrete spalling and rebar corrosion, so the law pulls the trigger forward for coastal stock.

After the initial inspection, a reinspection is required at least every 10 years. The requirement applies to condominium associations governed by Chapter 718 and to cooperatives under Chapter 719; single-family HOAs under Chapter 720 are not subject to it.

A useful framing for buyers: age alone doesn't tell you whether a building is overdue. A 28-year-old oceanfront tower is already past its 25-year coastal trigger, while a 28-year-old inland building still has two years before its clock strikes. Always check the certificate-of-occupancy date and the building's distance from the coast together.

Phase 1 vs Phase 2

The inspection proceeds in up to two phases, and the distinction matters enormously to the financial picture.

• Phase 1 is a visual examination of the building's primary structural systems by a licensed engineer or architect. If the inspector finds no signs of substantial structural deterioration, the building's obligation is satisfied and no Phase 2 is required until the next 10-year cycle.
• Phase 2 is triggered only when Phase 1 reveals substantial structural deterioration. It may involve destructive or non-destructive testing — opening walls, sampling concrete, evaluating reinforcement — and produces a detailed engineering analysis and repair scope.

The practical translation is straightforward. A clean Phase 1 means the building cleared its structural checkpoint. A Phase 2 trigger means an engineer has already found deterioration serious enough to warrant invasive investigation, and a repair scope — with a cost — is on its way. Phase 2 almost always implies a meaningful assessment.

How a milestone inspection differs from the SIRS

Buyers frequently conflate the milestone inspection with the Structural Integrity Reserve Study (SIRS), because both arrived in the same post-Surfside reform wave and both examine structural systems. They are different instruments with different jobs, and a complete building has both.

• The milestone inspection is physical. It answers: is this building structurally deteriorating right now, and does it need repair?
• The SIRS is financial. It answers: what will it cost to replace these same structural systems over time, and is the association funding reserves on a credible schedule to pay for it?

The two target the same components — roof, load-bearing walls, floor, foundation, fireproofing, plumbing, electrical, waterproofing, windows, and exterior doors. The milestone tells you what the building needs; the SIRS tells you whether the money is there. A building can pass its milestone inspection and still be dangerously underfunded on its SIRS — or fail its milestone while sitting on healthy reserves. Reading them together is the only way to see the full picture, which is why the two documents should always be requested as a pair.

The Miami-Dade and Broward 40-year programs vs the statewide law

The statewide milestone law is newer than the inspection programs that several South Florida jurisdictions have run for decades, and buyers in those counties may encounter both layers.

• Miami-Dade County has long administered a 40-year Building Recertification Program (and every 10 years thereafter), written into county code well before SB 4-D existed.
• Broward County runs a similar 40-year recertification program.
• Individual municipalities such as Surfside, Miami Beach, and others administer their own milestone notices and may impose additional local requirements.

These county programs predate the statewide milestone regime and now operate alongside it; the local programs have been harmonized with the state law rather than replaced by it. The state's coastal trigger (25 years within three miles of the coast) is in many cases earlier than the county 40-year mark — so in Miami-Dade and Broward, the statewide milestone is frequently the binding deadline for older oceanfront buildings, with the county recertification layered on top. The buyer's task is to confirm the building is current under both the state requirement and any applicable county or municipal program; a building can satisfy one and lag the other.

What a buyer should request and read

When a building is at or past its trigger age, request the full package and read three documents together: the inspection report, the board's response, and any resulting assessment. As of HB 913, the seller is required to provide an available milestone inspection report and the SIRS as part of the resale disclosure package for condos — but verify currency and completeness rather than assuming a delivered document is a clean one.

Specifically, look for:

1. Completion date and phase of the report. Was Phase 1 completed on schedule, late, or still pending? A building past its trigger with no report is a gap, not a non-event.
2. The Phase 1 conclusion. Did the engineer find substantial structural deterioration? This single finding determines whether a Phase 2 and a repair scope are coming.
3. Phase 2 status, if triggered. Has it started? Has a repair scope been published? What did the local building official order?
4. The repair cost estimate, if disclosed.
5. The board's response and funding plan. Has the association approved a special assessment, drawn down reserves, or arranged an association loan? Read the meeting minutes alongside the report — the board's deliberation is often where the real timeline lives.

How the assessment math usually works

When a repair scope exists, the financing logic is simple arithmetic: repair cost minus available structural reserves equals the gap. That gap is closed through some combination of a special assessment (most common, often spread over one to five years), an association loan recovered through higher dues, or a reserve drawdown where reserves are large enough and statutorily permitted.

The per-unit number depends on the building's unit count and the ownership-percentage allocation in the declaration. In Florida, the board may levy a special assessment without a full-membership vote unless the declaration specifically requires owner approval — which is why post-Surfside assessments have frequently landed at $20,000 or more per unit, sometimes well into six figures, on relatively short notice. A buyer who closes before an assessment is formally levied can still inherit it.

Red flags

Certain patterns in the milestone documentation should raise the level of scrutiny before closing:

• An overdue or missing inspection. A three-or-more-story building past its 25- or 30-year trigger with no completed Phase 1 carries unknown structural liability and a live compliance problem.
• Phase 2 triggered. An engineer has found deterioration serious enough to require invasive testing. The assessment is coming; the only open question is its size.
• A repair scope identified with no funding plan. The board is still deliberating, which usually means a vote within months. This is uncertainty, not safety.
• Required repairs with no money behind them. A documented scope and an underfunded reserve fund is the most direct path to a large near-term assessment.
• A two-year SIRS funding pause. HB 913 lets associations pause SIRS reserve contributions for up to two years to prioritize milestone repairs. That pause is a signal the building is diverting money to urgent structural work — investigate the underlying milestone findings.

What happens to financing and insurance when a building is non-compliant

Non-compliance is not just a regulatory abstraction; it directly affects whether a unit is insurable and financeable, which in turn affects whether you can close and whether you can resell.

On the insurance side, 2025 legislation bars Citizens Property Insurance — the state-backed insurer of last resort — from issuing or renewing policies for condo associations that are not in compliance with the milestone and SIRS requirements. Private carriers have moved in the same direction: many now refuse to bind a master policy without a current milestone inspection, a completed SIRS, and a recent replacement-cost appraisal. Compliance has effectively become a precondition of insurability.

On the financing side, the consequences cascade. A building that cannot secure affordable master insurance, or that carries an open structural deficiency and no funding plan, is harder to lend against. Conventional condo loans depend on the building meeting underwriting standards for reserves and insurance, and a non-compliant or deteriorating building can fall outside those standards — limiting the pool of buyers to cash purchasers and depressing values. This is why a milestone problem is not only a safety issue but a marketability issue that follows the unit.

A worked buyer example

Consider a buyer under contract on a unit in a 27-year-old, eight-story oceanfront building in Broward County. Because the building is within three miles of the coast, its milestone trigger was the 25-year mark — two years ago. The disclosure package includes a Phase 1 report dated last year that identifies substantial structural deterioration in the building's waterproofing and several balcony slabs, triggering Phase 2.

The Phase 2 report estimates $3.2 million in structural repairs. The SIRS shows roughly $900,000 in structural reserves. The gap — about $2.3 million — has to be funded. The building has 64 units, so a simple equal allocation implies a special assessment in the neighborhood of $36,000 per unit, before the declaration's ownership-percentage weighting is applied. The meeting minutes show the board discussing the scope but not yet voting on a funding mechanism.

For this buyer, the documents tell a coherent story: a coastal building past its trigger, a Phase 2 confirming deterioration, a quantified repair scope, a reserve fund that covers less than a third of it, and a board vote pending. The right move is not necessarily to walk away — it is to price the assessment into the offer, confirm the timeline with a Florida real estate attorney, and verify whether the contract allows a contingency tied to the pending board vote. The risk here is knowable; the danger is closing without having read it.
