What does a Fortis engineer photograph on your balcony, and why?

Direct answer: On a balcony we inspect, we photograph five things wherever they can be seen and safely reached: the elevation that locates it, the slab edge and underside, the guard connection at the structure, the walking surface and its drainage, and a detail shot with a scale reference. Each one supports something the report has to say later.

Florida's milestone inspection statute never uses the word "photograph." Both Broward and Miami-Dade require them, but in very different ways. Broward says it once, in prose: color photos "shall be included" to convey typical conditions, particularly where defects were found. Miami-Dade prints PROVIDE PHOTO next to the individual line item, 54 times, from settlement cracks to roof framing to guardrails.

One county tells the engineer what to photograph. The other tells the engineer to decide. Same statute, one county line apart.

This post is about what we photograph and why, and why we do not let the form decide it. It is general information about inspection methodology. It is not an assessment of any building, and it is not legal advice.

Less than boards expect of the statute, and more than the structural form shows.

Under Fla. Stat. §553.899(7)(a), a licensed architect or engineer performs "a visual examination of habitable and nonhabitable areas of a building, including the major structural components," producing a qualitative assessment of the building's structural condition. Visual. Qualitative. No camera named.

Two limits matter before anything else. First, §553.899(2)(a) is explicit that the purpose of a milestone inspection "is not to determine if the condition of an existing building is in compliance with the Florida Building Code or the firesafety code." Broward's own program text says the same thing in plainer words: "It is not the intent of the building safety inspection that buildings must be brought into compliance with current codes." It is a structural-condition assessment, not a code-compliance audit.

Second, a visual examination sees what is visible. Concealed deterioration can exist behind sound-looking concrete, and the statute anticipates that: §553.899(8)(f) requires the report to identify and describe any items requiring further inspection.

The reporting requirements in §553.899(8) are where documentation starts to carry weight. The report must "indicate the manner and type of inspection forming the basis for the inspection report" (8)(b). It must identify any substantial structural deterioration "within a reasonable professional probability," based on the scope of the inspection, describe the extent of that deterioration, and identify any recommended repairs (8)(c). And it must identify and describe items requiring further inspection (8)(f).

Note the qualifier in (8)(c): based on the scope of the inspection. The statute does not ask an engineer to certify a building. It asks for an honest account of what was examined, what was found, how far it extends, what it needs, and what could not be resolved.

Worth knowing if your building is in Broward or Miami-Dade: the county recertification program is how the milestone inspection requirement is administered and satisfied there. BORA's own report criteria track §553.899(8) closely, down to the same "based on the scope of the inspection" language, the extent of deterioration and the recommended repairs. It is one inspection process, not two.

Where the two counties actually differ

Municipalities inside Miami-Dade publish their own versions of the county form; the City of Miami Beach form revised January 16, 2025 is one of them, and it carries the same photographic structure.

So this is not a story about one county being lax. Both require photographs. The difference is that one county fixes the list and the other leaves it to professional judgment, and a discretionary standard is exactly the kind that produces two different records of the same balcony. What any particular report must contain is set by the authority having jurisdiction. What it does contain, in Broward, depends on who showed up.

That is the gap a documented standard closes.

The first photograph is not of a defect. It is the building, from far enough back to show which face and which level you are looking at.

The Miami-Dade County form asks for a photograph of each building elevation. An elevation shot on its own does not single out one balcony, because a building with repeating stacks looks the same at every floor, so it works paired with a location reference: a marked-up elevation or plan, a unit or tier designation, a floor number. Together they give a finding an address.

That pairing earns its keep on the return visit. On a re-inspection the question is rarely whether a crack exists. It is whether this is the same crack, and whether it has changed. Locating both photographs in the same place is the first requirement for answering that. It is not the only one: a conclusion about movement rests on measurements, not on two images that look different.

This is the shot most people picture, and the slab edge and underside are useful places to look. They are not necessarily where the earliest evidence appears.

The mechanism is reinforcement corrosion. Moisture and oxygen reach embedded steel, and chloride ingress or carbonation breaks down the steel's passive protection; the corrosion products occupy more volume than the steel they replace, and that expansion stresses the surrounding concrete from the inside. ACI 222R-19 and ACI 201.2R-16 describe it in detail.

What it looks like varies. Rust staining, cracking that follows the line of a bar, delamination that sounds hollow under a chain drag or hammer before anything shows on the surface, spalling, exposed reinforcement: these are possible presentations, not a fixed sequence. Any of them can appear without the others. More importantly, corrosion can be well advanced with nothing visible at all, particularly where a coating or tile covers the surface. The absence of a visible symptom does not rule out deterioration, and that is one of the reasons §553.899(8)(f) exists.

Where the balcony is a reinforced-concrete cantilever, flexural demand under gravity load is greatest at the support, not at the tip: that is where the negative moment is and where top reinforcement has to be continuous. So visible distress at the free edge does not establish that the edge is the structural problem. The edge is not unimportant either, because shear runs along the span and the edge carries its own local demands from guard anchorage, edge distance and cover. The point is that the engineer reads the distress against the structural system rather than the other way round, and other balcony systems carry load differently again.

Both county forms have a line for this, and they are not identical. Broward's masonry item 6.j rates rebar corrosion None Visible / Minor – patching will suffice / Significant – patching will suffice / Significant – structural repairs required. Its concrete item 9.d uses a different structure with no "Minor" grade; its second line asks instead for the location and description of members affected and the type of cracking. The Miami-Dade County form's equivalents sit at 6.k and 9.d and are structured differently again.

A rating on a scale is a judgment. The photograph does not make the judgment, and it does not make it verifiable on its own, because another engineer may need measurements, drawings, access to concealed conditions, or testing. What the photograph does is let a later reader see the condition the judgment was made about.

One caution stated plainly: cracking is not automatically deterioration. §553.899(2)(b) excludes surface imperfections such as cracks from substantial structural deterioration unless the licensed engineer or architect determines they indicate it, and the definition turns on structural distress or weakness affecting the general structural condition and integrity of the building. A photograph does not decide that. The engineer does.

A guard can fail while the balcony itself is sound, and the connection to the structure is one of the places to look hardest.

Guards attach in many ways: posts embedded in the slab, base plates anchored to the top surface, fascia-mounted brackets, members fixed to structural framing, glazing in a shoe. Whatever the arrangement, the inspection concern is the same: the connection, its fasteners or embedment, the sealant or interface around it, and the substrate it lands in. Water enters at that interface, corrosion begins where it cannot be seen, and the symptoms can arrive in any order: staining, cracking at the base, a loose fastener, a deteriorated plate, visible movement. Movement is not reliably the first sign, and anchorage capacity can be lost with no external sign at all.

Here the statutory purpose limit matters, so take the next paragraph as background rather than as a standard an existing guard is being measured against. A milestone inspection is not a determination that an existing guard complies with the current Florida Building Code.

For reference, the Code's design provisions for new work require guards along open-sided walking surfaces more than 30 inches above the surface below, measured within 36 inches horizontally of the open edge (§1015.2), generally 42 inches high (§1015.3), with openings generally not passing a 4-inch sphere (§1015.4). The strength requirements live in Chapter 16: §1607.9.1 sets a 50 pound per linear foot load and §1607.9.1.1 a 200 pound concentrated load, each with its own application conditions and exceptions. Those are design criteria for new construction. They are not a retrofit mandate for every existing guard.

They are also not something a photograph can answer. Capacity depends on the load path, the fasteners, the embedment depth, the edge distance, the substrate's condition and what is corroding inside it. A photograph of a base plate documents the visible condition and gives the engineer a reason to investigate further. It does not establish that the guard will resist a given load.

If a guard on your building is visibly loose, do not test it by leaning on it, and do not wait for the next scheduled inspection. Restrict access to that area as warranted and have it looked at promptly. Where a condition meets the Florida Building Code's definition of unsafe or dangerous, the building official is part of the process, and an engineer can tell you quickly whether you are there. A photograph records a condition; it does not make an unsafe one safe.

Water is the usual route to the steel, though not the only one. Moisture also travels through cracks, failed sealants, interfaces and permeable materials, and chloride-laden air does its own work on a coastal building with no ponding anywhere.

So we photograph what can be seen of the water path: the slope and where it drains, where it clearly does not, the condition of the coating or tile, the joint where the balcony meets the building wall, and any staining or standing water that shows where water sits after rain. What that establishes is limited and worth being honest about. Visible slope, drain locations, staining and ponding are observations. Actual drainage performance, and the condition of a waterproofing membrane under a tile bed, are not visible, and determining them takes observation during rain, exposure, or testing.

Neither county's structural form has an item dedicated to waterproofing. The word does not appear anywhere in Broward's 39-page program packet. Drainage does appear on both forms, but at item 11.e, under wood framing, which is not where a reinforced-concrete balcony's drainage belongs. So the balcony waterproofing and drainage picture has to be carried by the applicable condition fields, the narrative and the photographs. Whether that is the leading cause of balcony deterioration in South Florida is not something we are going to assert without data. That it is not a line item on either form is simply a fact about the forms.

The last photograph is one of the conditions above, taken close, with something of known size in the frame.

A scale reference helps a later reader interpret the image, and it helps the engineer tie a photograph to a number. It does not turn the photograph into a measurement. Camera angle, distance, lighting and where the scale sits all affect what the image appears to show, which is why a crack width that matters gets recorded with a comparator or gauge and written into the report, not estimated off a picture later.

The same goes for the word "baseline." A photograph with a scale in it is not a baseline on its own. A baseline is the whole record: the location, the orientation the photograph was taken from, the date, the measured dimension, the photograph, and the observation that goes with it. Assembled that way it can be repeated in ten years. Assembled loosely, it cannot.

Worth saying before it gets asked, because it is where photographic standards actually break down.

Not every balcony offers all five shots. An underside above an occupied area may not be reachable without equipment. A soffit may be enclosed. A balcony may be a different structural system with no exposed slab edge. Access to a private balcony depends on a resident being home.

A phase-one inspection also is not always every balcony. Scope may be all of them, a representative sample across elevations and floors, or specific locations chosen from what the first walk-through shows. Where we photograph, we photograph the same way; where we cannot, the report says so and says why, which is the part §553.899(8)(b) and (8)(f) are actually asking for.

Four questions, and they matter more than the photo list.

1. What is the scope, in numbers? Every balcony, or a representative sample? If a sample, how many, and chosen how across elevations and floors? A proposal that does not say is not comparable to one that does.
2. How will access to private balconies be handled? Notice to residents, scheduling, what happens when nobody is home, and whether unentered units are re-attempted or recorded as not examined.
3. How does "further inspection" get triggered, and what does it cost? §553.899(8)(f) means a phase-one report can legitimately end with open items. Ask what triggers that call, how it is communicated, and whether the follow-on work is priced in the proposal or quoted later.
4. Will the sealed report state plainly what was not examined? This is the one boards skip and regret. A report that lists only findings reads as complete. A report that also records the limits of the inspection is the one that holds up when somebody reads it in five years.

Ask every firm you are considering. The answers will differ more than the prices.

Not that five photographs are an inspection standard. They are not.

A documented procedure covers identification and location, access and its limits, what is observed, how it is assessed, what gets photographed and measured, how the report is prepared and checked, and how conditions needing further investigation are handled. The five photographs are one consistent piece of that.

What they are consistent against is the building, not the form. Miami-Dade prints the photographic instruction 54 times; Broward states it once and leaves the rest to judgment. Follow each county's form and you get two different records of the same balcony. Our photographic approach does not change at the county line. The investigation does respond to the building, because a concrete cantilever, a steel-framed balcony and a post-tensioned slab warrant different attention, and that is engineering judgment, not a documentation default.

The reason is simple enough. The next person to open the report is a future board, a buyer's engineer, a building official, or the engineer who inherits the next cycle. None of them will know which form was in use. All of them will need to see the condition the report describes.

Every Fortis assessment is performed to one documented standard and sealed by a licensed Florida PE who exercised direct responsible charge.

If your board is preparing for a milestone inspection or a county recertification and wants to understand what the engineering record should look like, contact us. We are glad to walk through it.
