Found Mold Before Listing Your Miami Home? What to Do First
Do I have to disclose mold when selling a house in Miami?
Yes, if you know about it. Florida has no mold-specific statute, but under Johnson v. Davis a seller must disclose known defects that materially affect value and are not readily visible to the buyer. Selling as-is does not remove that duty. The cleanest path is to fix the water source, use a licensed assessor and a separate licensed remediator, and hand the buyer the clearance report.
Fixing the mold is almost always the cheaper problem. Hiding it is the expensive one.
Florida has no mold disclosure statute and no mandatory mold form. What you have instead is a 1985 Florida Supreme Court case, Johnson v. Davis. If you know about a defect that materially affects value, and a buyer can't easily see it, you have to say so. Knowing includes what you learned by living there. A musty hall closet you've ignored for two summers counts.
Selling "as is" doesn't change that. The as-is language in the standard Florida Realtors/Florida Bar contract settles who pays for repairs. It doesn't settle whether you had to speak up. Our guide to what Miami sellers must disclose covers the full rule.
Why it keeps showing up in Miami listings
Humidity does most of the work. An air conditioner that dies in a closed-up house in August can turn a bathroom ceiling into a problem in a couple of weeks. So can a slow leak under a kitchen sink, or a roof leak left over from a summer storm that nobody checked twice. Empty houses are the worst, because no one is there to notice. If yours is vacant while listed, keep the AC running, and read what the vacancy clause in your insurance policy says before you leave it alone.
What to do when you find it
Fix the water first. Mold is a symptom. If the leak is still live, any cleanup is cosmetic and the next inspector will find it again.
Then decide how big it is. A few spots of surface growth above a shower with a dead exhaust fan is a handyman job. Staining across drywall, a smell you can't trace, or a known past leak is not. For those, hire a licensed mold assessor.
Hire one who does only assessment. Florida licenses assessors and remediators separately, and the same company can't do both jobs on the same structure within 12 months (Section 468.8419, Florida Statutes). The rule exists so the person diagnosing the problem isn't the person selling the fix. Use it. The assessor writes the scope, a different licensed remediator does the work, and the assessor comes back to test. That clearance report is the page a buyer's attorney wants to see.
Yes, this means you now hold a written report you'll have to disclose. That's the point. A buyer handed a clearance report and a receipt has a closed question. A buyer who finds the same mold on day nine of a 15-day inspection period, under a contract that lets them cancel for any reason, has a reason to walk or to reprice. They also have no idea what else you left out.
Check your policy before you spend anything. Many Florida homeowners policies cap mold remediation at $10,000, with optional increases to $25,000 or $50,000, and generally pay only when the mold follows a covered water event. Long-term leaks and poor ventilation are commonly excluded. A claim you expect to pay may not, and a filed claim can follow the house into a buyer's insurance quote. Ask your agent before you call anyone.
None of this is specific to one street, but it bites hardest in older homes. If you're preparing to sell in Coral Gables or Pinecrest, where plenty of houses have decades of roof, plumbing, and window history, the cost of finding out early is small. A documented, finished fix is a line item. A surprise during the inspection is a negotiation.
Before the photographer comes, open every closet, look under every sink, and press on the ceiling below any past roof repair. Find out now, on your schedule, instead of on day nine.
Quick answers
Is it illegal to sell a house with mold in Florida?
No. It is legal to sell a home with mold. What Florida law does not allow is hiding a known problem that materially affects value and that a buyer couldn't readily see.
Does selling as-is protect me from a mold claim?
Not for something you knew about. As-is language addresses who pays for repairs. It does not erase the duty to disclose known material defects.
Should I test for mold before I list?
If you have visible growth, a persistent smell, or a past water leak, yes, using a licensed assessor. If you have no signs and no history, testing is optional, but you should still fix any live moisture source.
Does homeowners insurance cover mold in Florida?
Often only partly. Many policies cap mold remediation at $10,000 and cover it only after a covered water event. Mold from slow leaks or poor ventilation is commonly excluded. Check your own policy.
