The short answer
Florida section 83.51 requires landlords to comply with building, housing and health codes, or keep structural components in good repair and plumbing in working condition. The statute does not mention mold, but unrepaired leaks can create it. Respond in writing, fix the water source, use a licensed remediator and keep records.
Your duties
What section 83.51 says
Section 83.51(1) covers codes, structural components and plumbing. Section 83.51(4) says you are not responsible for conditions caused by the tenant negligence or misuse. Section 83.56 sets a tenant notice process with a 7-day cure window. This is general information, not legal advice.
Response plan
Do this
- Acknowledge the report in writing the same day.
- Inspect and photograph. Find the water source.
- Fix the source: roof, plumbing, AC drain or ventilation.
- If the mold is more than about 10 square feet, hire a licensed remediator. See checking a license.
- Consider independent clearance. See PRV.
- Keep invoices, photos and messages.
Prevention
Lower your risk
- Service AC drain lines and drip pans on a schedule.
- Respond to leak reports fast.
- Tell tenants what to report and how.
Cause first
Is it a building problem or a use problem
Responsibility often depends on where the moisture came from. A roof leak, a failed supply line, a clogged AC drain and poor exterior drainage are building issues. Long-term unreported leaks by a tenant, heavy indoor moisture from drying laundry inside or an AC left off for weeks may point toward use. Many cases involve both. Photograph what you find and record how long it likely took to develop. Do not assume blame before you inspect.
First 30 days
A realistic timeline
- Day 0 to 2: acknowledge the report, schedule inspection, stop active water.
- Day 2 to 5: inspect, photograph, measure moisture, decide who fixes the cause.
- Day 5 to 10: get a licensed remediator’s estimate and approve the scope.
- Day 10 to 20: complete the cause repair, remediate and dry.
- Day 20 to 30: clearance check if substantial, rebuild, paint and re-inspect.
Larger jobs take longer. Tell the tenant the plan and update them if it changes.
Tenant needs
Belongings, access and relocation
- Ask the tenant to move valuables and furniture away from the work area, and offer help
- Give notice before any entry as the lease and section 83.53 require
- Explain that containment and air filtration will run during the work
- Offer another unit, rent adjustment or a short stay if the unit cannot be occupied, and put the agreement in writing
- Do not throw away tenant belongings without photographing them and getting consent
Costs
What to budget
Cost guides generally put professional mold work at roughly $10 to $25 per square foot, with a single room often between $1,500 and $6,000 and multi-room or HVAC jobs $6,000 to $15,000. A post-remediation check is commonly $300 to $500. Rebuild costs for drywall, paint and flooring are separate. Your insurer may cover part of it after a covered water loss, usually within a mold sublimit. See our cost guide.
Disputes
If the tenant and landlord disagree
Stay factual. Share the inspection results, the plan and the clearance report. If a tenant withholds rent or sends a termination notice, speak to a Florida landlord-tenant attorney before responding, because notice rules and timelines are strict. Do not retaliate. Keep communication calm and in writing.
Re-renting
Getting the unit back on the market
Wait for the unit to be dry and, for larger jobs, for the clearance report. Replace what was removed, keep the report with the unit file and consider telling new tenants what happened and what was done. Add a hygrometer or fan reminder to the move-in packet. See the landlord guide.
Common causes
Where rental mold usually starts
- AC drain lines and pans, especially in summer
- Supply lines under kitchen and bathroom sinks
- Water heaters and washing machine connections
- Roof and window leaks after storms
- Bathroom fans that are missing or vented into the attic
- Slab moisture or poor drainage on ground-floor units
- Vacant units with the AC turned off
Fixing these before a tenant reports them is cheaper than a claim. See our landlord guide for a maintenance plan.
Paper trail
What good documentation looks like
Keep the tenant’s first report, your acknowledgment, inspection photos, moisture readings, the contractor’s license and insurance, the scope, change orders, invoices, the clearance report and the final tenant communication. If the unit is later sold, financed or insured, the file explains what happened.
More questions
More questions, answered
Can I charge the tenant for mold remediation
Only if the facts and the lease support it, and the tenant caused the damage. A building leak is generally the landlord’s responsibility. Ask an attorney.
Do I need a licensed remediator for a small spot
EPA suggests homeowners can handle small hard-surface areas under about 10 square feet. Landlords should still document and fix the cause, and may prefer a licensed professional for a rental.
Should I get a clearance test
For larger jobs or a complaint, yes. It gives independent proof that the work is finished.
What if the tenant refuses entry
Follow the lease and section 83.53. Send written notice of the date and reason. If access is refused, consult an attorney before taking further steps.
Do I have to move the tenant out
Not always. Small, contained jobs can be done with the tenant in place. Large jobs, wet air handlers or health concerns may require a temporary move.
Questions
Common questions
Can I charge a tenant for mold?
It depends on cause and your lease. Mold caused by tenant negligence may be treated differently. Ask your attorney.
Do I need an assessor?
Not always. See assessor vs. remediator.

- When you first noticed it, and whether there was a leak, storm or AC problem before that.
- Whether you own, rent or manage the property, and whether you plan to involve insurance.
