Mold in a Florida Condo: Who Pays, You or the Association?

Condo mold has a feature that single-family mold doesn't: the water that caused it often started somewhere you don't control — a roof, a plumbing riser, an exterior wall, the unit above. That means the "who pays" question runs through three documents before anyone opens a wallet: your declaration of condominium, the association's master insurance policy, and your own HO-6 unit policy. Here's how the lines actually get drawn in Florida, and what to do when the association isn't moving.

The usual disclaimer, meant sincerely: this is general information, not legal advice. Declarations vary enormously, and for a five- or six-figure dispute, an hour with a condo attorney is cheap.

The boundary: your unit vs. the common elements

Florida's Condominium Act — Chapter 718, Florida Statutes — sets the baseline: maintenance of the common elements is the association's responsibility (§718.113(1)), except where the declaration assigns limited-common-element upkeep to the owner. What counts as a common element versus your unit is defined by your declaration of condominium, not by a universal state rule.

That said, most Florida declarations draw the line in a familiar place, often described as "drywall-in": the structure — exterior walls, the roof, floor slabs, plumbing risers and other pipes serving more than one unit — belongs to the association's side, while everything from the unfinished interior surfaces inward — paint, drywall finishes, flooring, cabinets, fixtures serving only your unit — belongs to you. Treat that as the typical pattern to check your own documents against, not as the law. The definitions section of your declaration, usually within the first dozen pages, is where the answer lives.

Why the boundary matters for mold: it usually decides who must fix the source. A failed roof or a leaking riser is normally the association's repair. The mold-damaged baseboards and drywall finish inside your unit may still be yours to deal with even when the water came from their side — which is exactly where the insurance split picks up.

The insurance split: HO-6 vs. the master policy

Florida draws the insurance line by statute, and it does not perfectly match the maintenance line — a regular source of confusion. Under §718.111(11), the association's master property policy must cover the condominium property essentially as originally installed — the building and its structure. But the statute then carves out a specific list that the master policy must exclude, making it the unit owner's responsibility to insure:

• floor, wall, and ceiling coverings
• electrical fixtures and appliances
• water heaters and water filters
• built-in cabinets and countertops
• window treatments
• all personal property within the unit

That list is what an HO-6 "walls-in" policy exists to cover. So after a common-element leak, the typical outcome is: the association (and its insurer) handles the structural repair and the building-side restoration, while your HO-6 responds for your flooring, cabinets, paint, and belongings — each policy subject to its own deductibles, and, for mold specifically, its own caps. Florida unit policies treat mold much like homeowners policies do: sudden-and-accidental water events are generally inside the tent, gradual leaks generally outside it, and mold remediation itself is often subject to a separate sublimit. Our Florida mold claim guide walks the claim mechanics, and the insurance hub covers the sudden-vs-gradual line in depth.

One practical implication worth underlining: report early on both tracks. Notify the association about the source, and put your own insurer on notice about the unit damage, even if you expect the association's side to bear most of it. Late notice is one of the most preventable ways condo owners weaken their own claims.

Your first move: written notice to the association

Phone calls to the management office don't create a record; a dated letter does. The notice should identify the suspected common-element source, describe the mold and moisture damage inside your unit, ask the association to inspect and repair the source, and request a written response with a timeline. Send it to the manager and the association's official notice address, certified mail with a return receipt, and keep a copy.

Our free letter generator has a condo association template that builds exactly this letter in your browser — nothing you type leaves your device. Date it, send it trackably, and photograph everything before anyone repairs anything.

Two reasons the letter matters more than it looks. First, mold spreads while a source stays active, so the date you put the association on notice often becomes the pivot point of every later argument about who let the damage grow. Second, associations answer to boards, insurers, and sometimes lawyers — a written, specific, reasonable request is the format all three of those audiences take seriously.

What the association owes you after notice

Once on notice of a common-element problem, the association's job under the declaration and Chapter 718 is to maintain and repair what it's responsible for — which in practice means inspecting the reported source and fixing it if it's theirs. Reasonable associations do this quickly, because an active leak is damaging their building too.

Give the process a fair window — access scheduling and contractor availability are real — but keep it on the record: confirm inspection dates in writing, ask for findings in writing, and follow up politely and datedly if weeks pass in silence. If the inspection shows the source is actually inside your unit (a failed supply line under your sink, say), the responsibility usually flips, and it's better to learn that early.

If the association stalls

When dated letters stop producing movement, Florida gives condo owners a ladder:

• A board-directed letter. Re-send the file — notice, photos, inspection findings, dates — addressed to the board of directors, asking for a decision at the next meeting. Boards sometimes simply haven't seen what the manager has been sitting on.
• The state's dispute program, for what it covers. The DBPR's Division of Florida Condominiums, Timeshares, and Mobile Homes runs a nonbinding arbitration and presuit mediation program for certain owner-association disputes under §718.1255. The honest caveat: the statute's definition of an arbitrable "dispute" excludes claims for damages to a unit based on the association's alleged failure to maintain the common elements — which is precisely what many condo mold cases are. So the program can help with some disagreements about what the association must do, but a damage claim typically heads toward court instead.
• An attorney letter. For unit-damage claims, a condo attorney's demand letter — backed by your dated record — is frequently what converts months of silence into a scheduled repair and a negotiated payment. If the amounts are large, this step is not optional; it's the path.

Through all of it, keep your own insurer in the loop. Insurers pursue each other through subrogation, and a well-documented file makes you easy to fight for.

Neighbor-to-neighbor leaks

When the water came from the unit above rather than a common element, the triangle changes: the association may still be involved (the pipe in the ceiling cavity might be a shared riser — their side — or your neighbor's branch line — the neighbor's side), but the core question becomes whether the neighbor was negligent and whose insurance responds. The playbook stays the same: notify the association and the neighbor in writing immediately, document the damage and the source before repairs erase the evidence, and put your HO-6 carrier on notice. Don't let "the neighbors said their plumber would handle it" substitute for a dated record — friendly arrangements have a way of dissolving when the remediation invoice arrives.

Renting in a condo? You're in two worlds at once

A renter in a condo building deals with both rulebooks: Chapter 83 governs your relationship with your landlord (the unit owner), and Chapter 718 governs the owner's relationship with the association. Practically, your written notices go to your landlord — the owner is the one with standing to push the association — but the escalation tools, deadlines, and risks on your side are the tenant ones. Our Florida renter's escalation path covers that side step by step, including the 7-day notice and the moves that need legal advice first.

When the repair finally happens

Whoever pays, insist on the fix being done right: the source repaired first, the mold remediation done by a licensed Florida professional, and — for any significant job — an independent clearance test at the end. Florida licenses mold assessors and remediators separately, and the same firm generally can't do both on the same property within 12 months; that separation protects you. You can find license-checked assessors and remediators on MoldVerified, and our guide to what to expect during remediation covers how a professional job should run.
