Milestone inspections, seen from the plant room
Florida's milestone inspection law is a structural statute, written with columns and slabs in mind. But the inspector walks the roof, the garage and the mechanical rooms, and much of what gets written down is water, corrosion and load — which is to say, the mechanical plant. This is what the law requires, where it reaches your equipment, and what to do before the letter arrives.
Who is covered
Which Florida buildings need a milestone inspection?
Under section 553.899(3) of the Florida Statutes, a milestone inspection is required for any building three habitable stories or more in height that is, in whole or in part, a residential condominium under chapter 718 or a residential cooperative under chapter 719. One- to four-family dwellings with three or fewer habitable stories are excluded, and the association bears the cost for the portions it maintains (s. 553.899(4)).
The word habitable was inserted in 2025 by House Bill 913 (chapter 2025-175). The statute does not define it, so whether a ground-floor parking level counts is a question for the local building official, in writing. Hotels, offices and rental apartments are outside the state statute unless part of the building is a condominium or cooperative, though Miami-Dade and Broward run their own programmes for most buildings regardless of ownership.
Timing
When is a milestone inspection due, and how often does it recur?
By 31 December of the year the building reaches thirty years of age, counted from its certificate of occupancy, and every ten years after that (s. 553.899(3)(a)). The local enforcement agency may bring the first inspection forward to twenty-five years where local conditions such as proximity to salt water justify it (s. 553.899(3)(b)).
The 2022 law set twenty-five years for any building within three miles of a coastline; the 2023 amendment replaced that with the local option, and in South Florida the coastal rule changed hands. Palm Beach County applies twenty-five years within three miles of the coast in the unincorporated county. Miami-Dade's recertification programme applies twenty-five years to condominium and cooperative buildings within three miles of the coast and thirty elsewhere. Broward's Building Safety Inspection Program applies twenty-five years to nearly every building in the county, examines the electrical system as well as the structure, and serves as compliance with the state requirement. Municipalities issue their own notices, so ask yours.
The transition deadlines of 31 December 2024 and 2025 have passed, and the agency may set timelines and penalties for buildings that have not complied (s. 553.899(10)). Two reliefs exist: an extension for good cause where an architect or engineer is already under contract (s. 553.899(3)(c)), and acceptance of a substantially compliant structural report prepared before 1 July 2022 (s. 553.899(3)(d)).
The procedure
What happens in phase one and phase two?
Phase one is a visual examination by an architect licensed under chapter 481 or an engineer licensed under chapter 471; phase two follows only if phase one finds substantial structural deterioration (s. 553.899(7)).
- Phase oneA visual examination of the habitable and non-habitable areas, including the major structural components. The scope is the load-bearing elements and primary structural members and systems as defined in section 627.706; it is not a code-compliance inspection, and not an inspection of the mechanical, electrical or plumbing systems as such. Surface imperfections such as cracks, sagging and signs of leakage do not count as substantial structural deterioration unless the inspecting professional decides they are a sign of it (s. 553.899(2)(b)). That judgement is where the mechanical plant enters.
- Phase twoOnly where phase one found substantial structural deterioration. The inspector may use destructive or non-destructive testing at the least disruptive representative locations, and must file a progress report within 180 days of the phase one report.
- The reportSigned and sealed, to the association and the building official. Under section 553.899(8) it must identify substantial structural deterioration and recommend repairs, say whether unsafe conditions were observed, recommend remedial or preventive repairs for items that are damaged but not structurally substantial, and list anything needing further inspection. An inspector who intends to bid on the repairs must disclose it in writing (s. 553.899(12)).
Amendments
What has changed since Senate Bill 4-D in 2022?
Amended in each of the three sessions since it was created; the 2026 session ended on 13 March 2026 without touching it.
| Session | Law | What it did |
|---|---|---|
| 2022 | SB 4-D, ch. 2022-269 | Created s. 553.899 and the structural integrity reserve study. Three stories or more; thirty years, or twenty-five within three miles of a coastline; every ten years after. |
| 2023 | SB 154, ch. 2023-203 | Replaced the three-mile rule with a local option; added good-cause extensions, acceptance of pre-2022 reports, the phase two progress report, the owner notices and a 365-day repair timeline that local governments could adopt; let a milestone inspection within five years serve as the reserve study's visual inspection. |
| 2024 | HB 1021, ch. 2024-244 | Amended the section; the height, age and interval thresholds did not change. |
| 2025 | HB 913, ch. 2025-175, effective 1 July 2025 | Inserted "habitable"; four-family exemption; made the 365-day repair ordinance mandatory; conflict disclosure. Reserve side: deadline moved to 31 December 2025, catch-all threshold raised to $25,000 and indexed, two-year pause after a milestone inspection, loans and lines of credit allowed. |
| 2026 | No enactment | SB 722 and SB 1498, on reserve study criteria, died in committee. |
The money
How does the structural integrity reserve study fit with the milestone inspection?
They are separate obligations: the milestone inspection (chapter 553) finds the condition, and the structural integrity reserve study, or SIRS (s. 718.112(2)(g) for condominiums, s. 719.106(1)(k) for cooperatives), prices it and compels the association to fund it. Unlike the milestone inspection, the SIRS covers plumbing and electrical by name.
A SIRS is required at least every ten years for each building of three habitable stories or more, covering the roof; the structure, including load-bearing walls and other primary structural members and systems; fireproofing and fire protection; plumbing; electrical systems; waterproofing and exterior painting; windows and exterior doors; and any other item costing more than $25,000, a figure the Division adjusts annually, whose neglect would affect those. Associations in existence on or before 1 July 2022 were required to complete the study by 31 December 2025.
The study rests on a visual inspection performed or verified by a licensed engineer or architect, or by a certified reserve specialist or professional reserve analyst; a milestone inspection performed within the past five years may be used in its place. For each item it states the estimated remaining useful life and replacement cost, and recommends an annual reserve that reaches the full cost by the end of that life. Where the remaining life exceeds twenty-five years, or cannot be determined, no replacement reserve is required.
The teeth are in the funding rules. Owners can no longer vote to waive or reduce reserves for these items, and the money cannot be spent on anything else. The 2025 amendments added flexibility, not relief: funding may come from assessments, lines of credit or loans, and an association that has received a milestone inspection within the previous two years may, by majority vote and for budgets adopted by 31 December 2028, pause SIRS contributions for at most two budget years to pay for the repairs it recommended.
The systems angle
Why does a structural finding land on the mechanical contractor's desk?
Because most of the water, corrosion and load a structural inspector records on a South Florida building originates in equipment, not in the structure. The report describes the symptom in structural language; the cause and the repair are mechanical.
Condensate as water intrusion
An air handler on this coast produces condensate all year. An overflowing pan, a dried trap, a line grown over with algae — each puts water onto a slab, and over years that water carries chloride to the reinforcement. The inspector writes "water intrusion at the mechanical room"; the cause is a drain line never flushed.
Corroded hangers and supports
Pipe and duct hang on threaded rod, strut and anchors set into the slab, and within sight of salt water galvanised steel does not last the life of the building. A hanger that fails drops a chilled-water main or a cast-iron stack, so the inspector lists it. Stainless is the repair.
Rooftop equipment loading
Replacement units are rarely the weight of the originals, and equipment is sometimes moved during a changeout without anyone reviewing the slab beneath it. The inspector will ask whether the load was engineered; no paperwork becomes a finding.
Penetrations and waterproofing
Every line set, vent, conduit and duct through a roof or wall is a hole in the waterproofing. Pitch pockets split, flashing lifts, sleeves were never sealed. Failed penetrations are among the commonest routes for water into a roof slab, and mechanical trades make them, not roofers.
Spalling under equipment pads
Water ponds beneath pads, pumps and tower basins, and a slab that is wet, salted and vibrated spalls there first. Below the building, cast-iron waste lines reach the end of their life at about the age the inspection falls due, and a leak saturates concrete from beneath. Both read as structural distress; both are plumbing scope.
Drainage
Blocked roof drains and scuppers leave standing water on a roof designed to shed it; blocked garage drains leave it on a post-tensioned slab; tower overflow that never reaches a drain runs across concrete. Drainage is the cheapest item here to put right and the dearest to ignore.
The report's duty under section 553.899(8) to recommend repairs for damaged non-structural items is where the condensate line, the corroded strut and the split pitch pocket end up, with a reserve study waiting to price them. Fix them before the inspector arrives and they are repairs in your service history rather than findings in a sealed report.
Preparation
What should a board have ready before the inspector arrives?
The building's drawings, its equipment schedule and its service history — because an inspector who can see what was done writes a narrower report, and a reserve analyst with evidence of maintenance assigns longer remaining lives than one who has only the age.
Documents
- Certificate of occupancy, date confirmed with the building department
- As-built drawings: structural, mechanical, plumbing, electrical and roof
- Prior reports: county recertification, earlier milestone or SIRS, insurer's surveys
- Permits and closeout files for roof, waterproofing, repipe and concrete work, and engineering letters for rooftop equipment that was replaced or relocated
Service history
- Equipment inventory: make, model, serial, age, weight, location, refrigerant
- Maintenance logs: condensate treatment, coil cleaning, drain flushing
- Water intrusion log and camera reports for drain and waste lines
- Infrared thermography of switchgear, which Miami-Dade requires at recertification for services of 400 amperes and above
Buildings without this history pay more at every stage: the inspector must treat what cannot be verified as suspect, so more is written up; the reserve analyst assigns the conservative remaining life; and contractors price the uncertainty into their bids. On a building approaching thirty, a maintenance file is the cheapest capital it will ever raise.
Repair or replace
How does the reserve study change the repair-or-replace decision?
Once a component is in the reserve study with a remaining useful life and a replacement cost, the association must fund that cost by the end of that life — so a repair that does not change the remaining life no longer saves money; it only moves the spending.
Take plumbing. Suppose the study gives a building's cast-iron stacks a remaining life of five years and a replacement cost of six hundred thousand dollars. The contribution is around one hundred and twenty thousand a year, and the owners cannot vote it away. Forty thousand dollars of spot repairs may stop the leaks, but unless the engineer revises the remaining life on the strength of it, the reserve line does not move and the association has spent forty on top of the hundred and twenty. Replace the stacks, and the new system's remaining life runs past twenty-five years — at which point section 718.112(2)(g) requires no replacement reserve at all. The replacement is frequently the cheaper accounting as well as the better engineering.
The opposite error is as common. Remaining useful life is a condition judgement, not an arithmetic of age, and a component maintained on a documented schedule can carry a longer life than the tables suggest. Boards that let an analyst work from age alone fund replacements they may not need; boards that hand over a service history are, in effect, negotiating the reserve.
Sequencing
What should you do in the twelve months before a milestone inspection is due?
Fix the cheap, visible mechanical causes of water and corrosion before the phase one walk, so that they appear in your records as completed repairs rather than in the report as findings, and have the paperwork assembled before the engineer asks.
- Twelve months — fix the date and the jurisdictionConfirm the certificate of occupancy date with the building department, and ask in writing whether it applies twenty-five or thirty years, whether it runs its own programme, and how it counts habitable stories for your building.
- Ten months — engage the engineerRetain the architect or engineer early enough that a good-cause extension is available if needed, obtain the section 553.899(12) disclosure in writing, and send the drawings and prior reports ahead.
- Nine months — walk the plantRoof, mechanical rooms, garage and risers, with the mechanical contractor and a camera. Flush every condensate line, clear every drain and scupper, replace corroded hangers, re-seal failed penetrations, trace every leak to its source, and photograph everything before and after.
- Six months — electrical and heavy equipmentWhere the local programme includes electrical, as Miami-Dade's and Broward's do, have the switchgear thermographed and findings corrected. For every rooftop unit, tower or generator replaced since the last inspection, locate or commission the engineering letter for its load.
- Three months — align the reserve studyIf a SIRS is due, decide whether the milestone inspection will serve as its visual inspection, and hand over the inventory and service history so that remaining lives are set on evidence.
- After the report — act inside the clocksSummary to every owner within 45 days. Findings priced and sequenced, separating repairs that reset a remaining life from those that merely defer one. If phase two is required, the 365-day repair clock starts when the agency receives that report.
Questions
What boards and chief engineers ask about milestone inspections
Does a hotel need a milestone inspection in Florida?
Not under section 553.899, which applies only to buildings held in whole or in part as a residential condominium or cooperative. In Miami-Dade and Broward counties, however, the local building safety programmes apply to most buildings regardless of ownership, and both examine the electrical system too.
Does the milestone inspection cover HVAC, plumbing or electrical systems?
No. It is a structural inspection of load-bearing elements and primary structural members and systems. Mechanical systems enter it through their effects — water, corrosion and load — and through the report's duty to recommend repairs for damaged non-structural items. Plumbing and electrical are, however, named components of the structural integrity reserve study.
Can a milestone inspection be used for the structural integrity reserve study?
Yes. Section 718.112(2)(g) allows a milestone inspection performed within the past five years, and meeting the paragraph's requirements, to be used in place of the visual inspection portion of the reserve study. The remaining-life and funding analysis still has to be done.
Where we fit
What Amalfi Mechanical does before and after the inspection
The Mechanical division begins with a written equipment inventory — make, model, serial, age, condition and estimated life remaining for every unit — which is the document the engineer and the reserve analyst will ask for first. The pre-inspection walk, the condensate and drainage work, the hanger and penetration repairs and the engineering for rooftop loads are ordinary scope, with closeout files written to be handed to an inspector.
The buildings reaching thirty on this coast sit in Miami Beach, Fort Lauderdale and Boca Raton; response targets by county are on the coverage page. If a notice has arrived, write to us or send the certificate of occupancy date to [email protected].
