Milestone Inspection vs. 40-Year Recertification in Florida: What's the Difference?

If you own or manage a building in South Florida, you've probably heard "milestone inspection" and "40-year recertification" used as if they're the same thing. They're related, but they are two separate legal requirements — and in Miami-Dade and Broward, your building can be subject to both at the same time. Confusing them is how owners miss deadlines and get surprised by fines.

Here's the plain-English breakdown.

‍

The short answer

A milestone inspection is a statewide requirement created after the Surfside collapse. A 40-year recertification is an older *local* program that has existed in Miami-Dade since 1975 and in Broward shortly after. The milestone law didn't replace the local recertification ordinances in those two counties — it layered on top of them.

So:

- Outside Miami-Dade and Broward: you generally deal with the milestone inspection only.

- Inside Miami-Dade or Broward: you may have to satisfy both the county recertification ordinance and the state milestone inspection.

What the milestone inspection is

The milestone inspection was established by Florida Senate Bill 4-D in 2022 and is codified in Florida Statute 553.899. It applies to condominium and cooperative buildings that are three or more stories tall. It does not apply to single-family homes or duplexes.

The key facts:

- First inspection is due when the building reaches 30 years of age, measured from the date its certificate of occupancy was issued — or 25 years if the building sits within three miles of the coastline.

- Repeat inspections are required every 10 years after that.

- The inspection runs in two phases. Phase 1 is a visual structural assessment by a licensed engineer or architect. If no substantial structural deterioration is found, you're done. If the engineer suspects a problem, Phase 2 is triggered — more detailed, sometimes destructive, testing.

- The report must be signed and sealed by a Florida-licensed Professional Engineer or architect and submitted to both the association and the local building official.

The same 2022 legislation also created the Structural Integrity Reserve Study (SIRS) requirement, which forces associations to fund the long-term repair items the inspection tends to uncover.

What the 40-year recertification is

The 40-year recertification is the long-standing Miami-Dade and Broward program. Miami-Dade's version dates to a 1975 ordinance and was strengthened in 2022 alongside the new state law.

The key differences from the milestone inspection:

- It applies to a broader set of buildings, not just condos and co-ops three stories or taller.

- It covers both structural and electrical safety — the electrical scope is a real distinction that catches owners off guard.

- It is triggered by a Notice of Required Recertification mailed to the property owner, and the signed-and-sealed report is due within 90 days or 180 days of that notice.

- Certain small structures are exempt (for example, single-family homes and duplexes).

In Miami-Dade, the county integrated the new milestone rules with its existing recertification ordinance, which is why an older coastal condo can legitimately owe a structural milestone inspection, an electrical recertification, *and* a reserve study within overlapping windows.

Why this matters for your deadline

The most expensive mistake we see is an owner who completes one requirement, assumes they're covered, and lets the other lapse. A Miami-Dade condo board that handles its milestone inspection but ignores the electrical recertification scope is still out of compliance — and the building official treats that as a missed deadline.

The fastest way to remove the ambiguity is to have one licensed firm look at your building's age, location, and ownership structure and tell you exactly which requirements apply and when. Because Mimik Solutions holds both a Florida Professional Engineer license (PE85427) and a General Contractor license (CGC1531655), we can perform the structural and electrical inspection and scope any repairs the report surfaces — without you coordinating a second firm.
