Florida SIRS requirements after SB 4-D: what every board needs to know

July 13, 2026 · 4 min read

The 2021 collapse of the Champlain Towers South building in Surfside changed Florida law for condominium and cooperative associations. The legislation that followed, commonly referred to by the bill number SB 4-D and amended in later sessions, created two obligations that many boards had never faced before: a milestone structural inspection and a structural integrity reserve study, known as a SIRS. This guide explains what those are, which buildings are affected, and how a board should approach them.

Two separate requirements, often confused

Boards frequently blur the milestone inspection and the SIRS into one thing. They are related but distinct.

The milestone inspection is a structural inspection of the building itself, performed by a licensed engineer or architect, that assesses the condition of load-bearing and structural elements. It produces a report on the building's structural status and whether further evaluation or repair is needed.

The structural integrity reserve study (SIRS) is a reserve study focused specifically on the structural and safety-critical components of the building. Unlike a general reserve study a board might commission voluntarily, the SIRS is scoped by statute and its structural components generally cannot be waived or underfunded the way boards once could vote to do.

You can think of the milestone inspection as answering "is the building sound right now," and the SIRS as answering "is the association setting aside enough money to keep it sound."

Which buildings are covered

The structural integrity reserve study requirement generally applies to condominium and cooperative buildings in Florida that are three stories or more in height. Height, measured in stories, is the key trigger. Single-family HOA communities and low-rise buildings below that threshold are treated differently and in many cases are not subject to the SIRS requirement at all.

Because the specifics of height measurement, building type, and applicable deadlines have been refined across multiple legislative sessions, a board should confirm its own status with a licensed engineer and, where needed, association counsel rather than relying on a general summary. The framing above is reliable; the precise deadline that applies to your building depends on its location and characteristics.

What the SIRS must cover

The SIRS is required to study a defined set of structural and safety-critical components. In broad terms these include the roof, the load-bearing walls and primary structural systems, the floor and foundation, fireproofing and fire protection systems, plumbing, electrical systems, waterproofing and exterior painting, windows and exterior doors, and any other item with a deferred maintenance or replacement cost above a statutory threshold.

The important shift for boards is that reserves for these structural components carry more weight than the discretionary reserve categories many associations used to manage loosely. The old practice of voting each year to waive or reduce reserve funding does not extend to the structural components a SIRS covers in the same way it once did.

Why underfunding is no longer a quiet option

Before these reforms, many Florida associations kept assessments low by repeatedly waiving reserves. That deferred the cost, not the need, and Surfside made the human stakes of that deferral impossible to ignore. The current framework is designed to force the structural math into the open: the study identifies what the building will need, and the association is expected to fund toward it.

For boards, this means the SIRS is not a formality to file and forget. It sets a funding expectation that shapes budgets and assessments for years, and owners will feel it. Communicating why the numbers moved, and tying them back to the statute rather than to board discretion, is part of getting owners on board.

Where to start

If your building is three stories or taller and you have not yet completed a SIRS or a milestone inspection, the first step is a conversation with a licensed engineering firm that does this work in your county. The engagement is more specialized than a routine reserve study because the structural components must be assessed by the right credentialed professional.

Before you commission anything, it can help to get a rough sense of the numbers so you walk into that conversation informed. Common Elements hosts a free SIRS Reserve Planner that lets a board sketch out its structural reserve picture as a starting point. It is a gut-check, not a substitute for the real engineering-backed study, but it is a useful place to begin.
