Florida Mold Law: Licensing, the 10 Sq Ft Rule and Conflicts

Florida mold law is Part XVI of Chapter 468 of the Florida Statutes, sections 468.84 to 468.8424. It requires anyone who performs mold assessment or mold remediation on more than 10 square feet of mold to hold a license from the Florida Department of Business and Professional Regulation (DBPR), and it bars assessors from profiting from the cleanup they recommend.

Quick answer: In Florida, a paid mold assessment or mold remediation involving more than 10 square feet of mold must be done by a DBPR-licensed mold assessor or mold remediator. An assessor cannot remediate a structure it assessed in the past 12 months and cannot pay or accept referral fees with remediators. Indoor Air Quality Solutions (IAQs) is an independent, assessment-only firm: we inspect, test and write remediation protocols under this law, and we never do the remediation.

What does Florida mold law cover?

Florida mold law licenses two separate roles, the mold assessor and the mold remediator. The statute's definitions in section 468.8411 set the scope:

• Mold assessment is a process that includes physical sampling and a detailed evaluation of building history and inspection data to form a hypothesis about the origin, identity, location and extent of mold growth greater than 10 square feet.
• Mold remediation is the removal, cleaning, sanitizing, demolition or other treatment of mold or mold-contaminated material greater than 10 square feet.
• Mold assessor is any person who performs or directly supervises a mold assessment. Mold remediator is any person who performs mold remediation.

Work that also requires a construction license under Chapter 489 still needs that license; a mold license does not replace it.

What is the 10 square foot rule?

The 10 square foot rule is the size threshold built into the statute's definitions. Assessment and remediation of mold growth greater than 10 square feet fall under the licensing law; smaller areas are outside those definitions.

In practice, the visible patch is rarely the whole picture in a Florida home. Growth behind drywall, under flooring or inside an air handler often extends well past what you can see, which is why the first question in an assessment is usually how far the moisture went, not how big the stain looks.

Can the same company inspect and remediate mold in Florida?

Generally no. Section 468.8419 says a mold assessor may not perform or offer to perform mold remediation on a structure where the assessor or the assessor's company provided a mold assessment within the last 12 months.

The statute makes one exception: a certified Division I contractor (as classified in section 489.105). If such a contractor assesses and then offers to remediate, the department may require the remediation contract to disclose that the homeowner has the right to request competitive bids.

The same section also prohibits an assessor from:

• Inspecting for a fee any property in which the assessor or the assessor's company has a financial or transfer interest
• Accepting or offering any compensation, inducement or reward for referrals to or from a mold remediator
• Accepting an assessment whose conclusions, or whose fee, is contingent on the results
• Using titles such as "licensed mold assessor" or "certified mold assessor" without meeting the law's requirements

This is the reason IAQs is assessment-only. We write the mold remediation protocol, any licensed remediator can bid on it, and our recommendations carry no financial stake in the cleanup.

What does it take to become a licensed mold assessor in Florida?

A Florida mold assessor must pass the required examination, be of good moral character and meet an education and experience requirement under section 468.8413. The options are a 2-year associate degree (or equivalent) with at least 30 semester hours in a related science plus 1 year of documented field experience in microbial sampling or investigations, or a high school diploma (or equivalent) with at least 4 years of that field experience.

Assessors must also have documented training in water, mold and respiratory protection, and carry at least $1 million in general liability and errors and omissions coverage for both preliminary and post-remediation assessments (section 468.8421).

How do you check a Florida mold assessor's license?

Look up the person or company by name or license number on the DBPR license search before you hire them. Florida mold assessor licenses use the prefix MRSA. For example, John P. Lapotaire, CIEC, principal of IAQs, holds Florida Mold Assessor license MRSA #4.

Then ask three questions:

1. Does the company also perform remediation, or have a preferred remediator it refers you to?
2. Will you receive a written report and, if needed, a written remediation protocol?
3. Which laboratory analyzes the samples, and is it AIHA-accredited?

What happens if an assessor or remediator breaks the mold law?

The department can discipline licensees under section 468.842 for violating the part, filing a report the licensee knows is false, deceptive advertising, or fraud, negligence or incompetence in mold assessment or remediation.

For a property owner, the practical risk is a report or remediation scope written by someone with a conflict of interest. That can mean unnecessary work, missed moisture sources, or documentation that is harder to rely on with an insurer, a buyer or in a dispute.

Does Florida mold law apply to landlords and home sellers?

The licensing law governs who may perform paid mold assessment and remediation; it does not by itself set landlord repair deadlines or seller disclosure duties. Those questions fall under other areas of Florida law, so if you are in a lease or sale dispute, ask a Florida attorney about your obligations.

What the licensing law does affect is the paperwork. When a landlord, condo association, buyer or seller needs to document a mold condition, a report from a licensed, independent assessor is the record most parties expect. IAQs also provides litigation support when a matter is already in dispute.

What does a licensed mold assessment include?

A licensed assessment typically includes a building history interview, a visual inspection, moisture mapping, and sampling when it helps answer a specific question. Samples go to an AIHA-accredited laboratory.

At IAQs, a residential mold inspection usually takes 1.5 to 3 hours on site, and every project gets a written report, typically within 3 to 5 business days of the visit, with lab sections added once results return. A written remediation protocol is included when the findings call for one. After cleanup, a post-remediation verification inspection confirms the work met the protocol.

Quick answers

Do all mold inspectors in Florida need a license? A paid mold assessment of mold growth greater than 10 square feet must be performed or directly supervised by a DBPR-licensed mold assessor. Using a title like "licensed mold assessor" also requires meeting the law. A general home inspector without a mold assessor license should not perform that assessment.

Can a mold assessor recommend a remediation company? An assessor may not accept or offer any compensation, inducement or reward for referrals to or from a mold remediator, under section 468.8419. Many independent assessors, including IAQs, avoid referring a preferred contractor at all and let the property owner choose.

Are DIY mold test kits regulated by Florida mold law? The licensing law regulates people paid to perform mold assessment, not the kits homeowners buy. A kit result is not a mold assessment as the statute defines it, because it lacks the building history and inspection evaluation an assessor performs.

Is mold under 10 square feet covered by the law? The statute's definitions of mold assessment and mold remediation apply to growth greater than 10 square feet, so smaller areas fall outside those definitions. Hidden growth is often larger than the visible patch, so measure the moisture problem, not just the stain.
