Condo drilling rules in South Florida, explained

In a house you decide where the holes go. In a condo you do not, and the reason is not the association being difficult. Some of the surfaces in your unit are not yours, and one of them can be genuinely dangerous to drill.

Here is how the ownership actually splits, what your association is really protecting, and how to ask for permission in a way that gets a yes.

The walls in your unit are not all the same

Florida condominiums are governed by Chapter 718 of the Florida Statutes and, more specifically for your purposes, by your building’s own declaration of condominium. The declaration is the document that defines where your unit stops and the common elements begin. Read it. It is usually less painful than it sounds and the boundary description is often a single paragraph.

In most declarations the unit is defined as the airspace within the unfinished surfaces of the perimeter walls, the floor and the ceiling. That means the drywall face in the middle of your living room is generally yours, and the concrete behind it generally is not.

Interior partition walls

These are the non-structural walls inside your unit that separate your bedroom from your hallway. In most buildings they are yours to hang things on, and in most modern condos they are light-gauge metal studs with drywall on both sides rather than wood framing.

Metal studs change the fastener conversation. A wood screw does not hold in a 25-gauge steel stud the way it holds in lumber. You want screws designed for metal framing, or toggle-style anchors that bear on the back face of the drywall, and for a TV you often want a mount that spans studs on a plate. Drywall anchors explained covers what each type actually holds.

Even in an interior wall, check what is inside it before you drill. Condo partitions carry plumbing risers, dryer vents, low-voltage runs and sometimes fire sprinkler branch lines. Hitting a sprinkler line floods your unit and everything below it.

Demising walls

A demising wall is the wall between your unit and the neighbor’s, or between your unit and a corridor. These are almost always common elements, they are almost always fire-rated assemblies, and they frequently have an acoustic design that a penetration ruins.

A fire-rated wall works as a tested assembly. Its rating depends on the whole build-up staying intact, and every hole through it is a breach that has to be firestopped correctly to preserve the rating. Corridor walls in particular are part of the building’s egress protection. This is not paperwork — it is the wall that is supposed to buy people time.

Assume you may not drill through a demising wall. Shallow fastening into your side of the drywall is sometimes permitted; going through it essentially never is.

Exterior and perimeter walls

These are the building envelope, and they are common elements in almost every declaration. They are usually concrete or block, they are waterproofed on the outside, and near the coast they have a corrosion problem waiting for an excuse.

Two real risks:

Water intrusion. The exterior finish and coating are a system. A penetration through it, especially one that is not sealed properly, gives wind-driven rain a path into the wall. In a South Florida tropical downpour that path finds your neighbor’s ceiling before it finds you.

Concrete spalling. Coastal buildings have chloride in the air and eventually in the concrete. When moisture reaches embedded steel, the steel corrodes and expands, and expanding steel cracks concrete off in sheets. A drilled hole that reaches or nicks a bar, then admits moisture, is exactly how that starts. Spalling repair on a high-rise is scaffolding, engineers and six figures.

Balcony slabs and railings fall under the same logic and are usually explicitly off limits.

The one that is actually dangerous: post-tension slabs

If you take one thing from this article, take this.

Many mid- and high-rise buildings in South Florida, and some slab-on-grade foundations, use post-tensioned concrete. Steel tendons are run through the slab, and after the concrete cures they are stretched to very high tension and anchored at the edges. That tension is what makes a thin slab span a long way. It is permanent, it is enormous, and it is invisible from below.

Drilling or coring into a post-tensioned slab and striking a tendon is dangerous at the moment it happens and structurally serious afterward. A severed tendon does not simply stop working at that point — it can release along its length, and the slab loses capacity it was designed to have. Repairs are specialist engineering work.

Tendons are not laid out in a simple grid you could guess at. They run in two directions, they are often draped so their depth changes across the span, and they bunch near columns. There is no rule of thumb, no safe depth, and no “just go shallow” that I will put in writing.

So the rule is simple and absolute:

Never drill into a concrete slab, ceiling or wall that might contain tendons without the building’s structural drawings and, in most cases, a scan.

What that means in practice:

1. Ask management whether the building is post-tensioned. They will usually know, and if they do not, they can tell you who does.
2. Ask for the structural as-built drawings for your floor. Associations often have them. They will show whether the slabs are post-tensioned and roughly how the tendons run.
3. If anything is going into concrete, get a scan. Ground-penetrating radar performed by a firm that does concrete scanning will locate tendons, rebar and conduit before a bit turns. It is not expensive relative to what it prevents, and many buildings require it.
4. Do not accept “it’s probably fine.” Not from a neighbor, not from a contractor, not from me. Get the drawings.

This is why ceiling fans, ceiling-mounted TV brackets, track lighting and recessed cans are so often flatly banned in condos here. The ceiling is the underside of a structural slab.

Who controls what

Surface	Usually owned by	Typical restriction	What to do first
Interior partition wall	You	Generally permitted; some buildings still want notice	Check for plumbing, sprinkler and electrical inside
Demising wall to a neighbor	Common element	No through-penetrations; fire and acoustic rating	Written approval, and usually a no
Corridor wall	Common element	Fire-rated egress assembly; expect a no	Written approval
Exterior perimeter wall	Common element	Waterproofing and spalling risk; usually prohibited	Written approval and engineer sign-off
Ceiling — underside of slab	Common element	Post-tension and rebar risk; commonly prohibited	Structural drawings and a scan, or do not drill
Floor slab	Common element	Same as ceiling; also affects the unit below	Structural drawings and a scan, or do not drill
Balcony slab, ceiling and railings	Common element	Waterproofing, spalling, hurricane load path	Almost always prohibited
Window and door frames	Common element	Envelope and impact-rating compliance	Do not fasten to them

Your declaration wins over any table on the internet. Read it.

Why associations care more than they used to

Florida tightened condominium building-safety law after the Surfside collapse. Buildings three stories and higher are now subject to milestone structural inspections at 30 years, repeating every 10 years after that, and associations must maintain a structural integrity reserve study covering major structural and waterproofing components.

One detail worth getting right, because the older version of it is still repeated everywhere: there is no longer an automatic 25 year trigger for buildings within three miles of the coast. SB 154 in 2023 deleted that and replaced it with local discretion. Your local enforcement agency may set the milestone at 25 years instead of 30 where local conditions justify it, including proximity to salt water, but that is a determination the agency makes rather than something the distance to the beach decides on its own. Ask your building department what applies to your address.

The effect on you is direct. Boards now have engineering reports naming their concrete and waterproofing as items they are legally responsible for, and they are correspondingly less relaxed about residents putting holes in either. A rule that felt fussy ten years ago is now attached to a report with the board’s name on it.

That is worth knowing when you write your request. You are not arguing with an opinion.

Certificates of insurance, and why you get asked for one

Most buildings will not let a vendor through the door without a certificate of insurance on file with management. What they typically ask for is general liability coverage with the association named as an additional insured, and workers’ compensation coverage where it applies.

The reason is straightforward. Work inside a unit can damage the building or a neighbor’s home, and the association would rather have a policy behind that than a conversation.

Two practical points:

• Ask what your building requires before you book anyone. Coverage amounts, additional-insured wording and how far in advance the certificate must be filed all vary by building, and some managers want a week.
• Ask whoever you plan to hire what they can provide. Not every trade or handyman carries what a given building demands, and it is far better to find that out on the phone than at the loading dock.

If your building’s requirements are strict, that narrows your options, and it is a legitimate reason to hire a company set up for condo work.

Work hours, elevators and access

Buildings run on rules that have nothing to do with drilling and everything to do with whether the job happens on the day it was booked.

• Work hours. Usually weekday business hours only, no weekends or holidays. Many buildings ban noisy work outside a narrower window than the general access window.
• Elevator reservations. Service or freight elevators are typically booked in advance, sometimes days ahead, sometimes with a deposit.
• Elevator pads. Buildings that require protective pads generally require staff to hang them, which means the reservation is not optional.
• Loading dock and parking. Many towers have no vendor parking at all, or a strict time limit at the dock. This affects how long a job takes and what it costs.
• Sign-in at the desk. Vendors are usually logged in, sometimes with ID, and residents often have to authorize access in writing beforehand.
• Debris. Most buildings prohibit construction debris in the trash chute or the resident dumpster. Packaging from a large TV or a furniture delivery has to leave with the vendor.
• Notice to neighbors. Some buildings require it for noisy work. It costs nothing and buys goodwill.

None of this is unreasonable, but all of it is time, and time is what a job costs. What a handyman costs in South Florida explains how building access shows up in a quote.

How to actually ask your association

The difference between a fast yes and a two-month silence is usually the quality of the request. Managers are not trying to stop you; they are trying not to approve something vague that comes back on them.

A good request is short, specific and easy to approve. Send it by email so there is a record.

Include:

1. Your unit number and contact details.
2. Exactly what you want to do. “Wall-mount a 65-inch television” beats “do some work in the living room.”
3. Which wall, described precisely, with a photo and a mark on the floor plan. State that you believe it is an interior partition wall and not a demising or exterior wall.
4. What fastener goes in and how deep. “Four toggle anchors into drywall on metal studs, penetration under two inches” tells them what they need to know.
5. Who is doing the work, and that you will have their certificate of insurance filed in advance.
6. When, with proposed dates inside the building’s permitted work hours, and a note that you will book the service elevator.
7. What you will not do. Explicitly: no drilling into the ceiling, floor, exterior wall or demising wall. This sentence does more work than the rest of the email.
8. A question, not a demand. Ask whether approval is required and what form they need.

If concrete is genuinely involved, add that you will provide a GPR scan report and the structural drawings before anything is drilled, and ask whether the association has drawings you may reference.

Keep the approval. Print the email. When a manager changes in three years and someone asks why there are holes in your wall, that email is the answer.

If the answer is no

Plenty of good options never touch a wall:

• Floor-standing TV stands. A good one behind a low console reads as a wall mount from the sofa, and it comes with you when you move.
• Tension-pole systems that brace between floor and ceiling with pressure rather than fasteners. Check the ceiling can take the point load and that the building allows them.
• Freestanding shelving and media walls. Anchor them within the unit’s own structure where permitted, or choose units wide enough to be stable on their own.
• Leaning mirrors and floor-standing art. Restrain them at floor level rather than fastening to the wall.
• Existing picture rails or hanging systems. Many older buildings have them, and many newer ones will approve a rail installed on an interior wall.
• Adhesive hanging systems for genuinely light frames. Read the weight limit, halve it, and do not put anything irreplaceable on one.

For heavier items, how to hang a heavy mirror explains why a wall fixing is not something to improvise.

When to stop

Stop before you drill if you do not know what the wall is. Not “it feels like drywall” — whether it is a partition, a demising wall or the perimeter.

Stop if the surface is concrete and you do not have drawings or a scan. This is the one that is not negotiable, and it is the reason this article exists.

Stop if you hit something unexpected at depth. Back the bit out, do not push through it, and find out what it is.

Stop if the building says no. Written approval protects you, and unapproved work in a condo can end up as a demand to restore the surface at your expense, sometimes years later at closing.

When it’s worth calling someone

Condo work is as much paperwork and building access as it is drilling, and getting the wall type wrong in a tower is a very expensive mistake. Handy Daddy does TV mounting and wall work in buildings across Fort Lauderdale, Boca Raton and the rest of Broward, Palm Beach and north Miami-Dade, working to the association’s approved scope. If your walls turn out to be block rather than partition framing, mounting a TV on a concrete block wall covers what that job actually involves, and DIY or hire a handyman is a straight take on where the line falls.
