This is general information, not legal advice. Permit rules change, and no Collier County or City of Naples page we found addresses "mold remediation permits" by name. Confirm your project with the building department before work begins.
Two separate questions: a license and a permit
People often ask "does mold remediation require a permit in Florida?" as if it were one question. It's really two, and they're handled by different agencies.
- The mold license (state). Florida Statutes s. 468.8411(5) defines "mold remediation" as "the removal, cleaning, sanitizing, demolition, or other treatment, including preventive activities, of mold or mold-contaminated matter of greater than 10 square feet that was not purposely grown at that location." Mold assessment over 10 square feet is defined the same way in s. 468.8411(3). That work requires a state license from the Department of Business and Professional Regulation (DBPR), which licenses individuals, not businesses.
- The building permit (local). Whether tearing out or replacing drywall needs a permit is decided by your local building department: Collier County for unincorporated areas, or the City of Naples or the City of Marco Island inside those cities.
Florida mold licensing is separate from permits. A mold license doesn't replace a building permit, and getting a permit doesn't make someone a licensed mold remediator. The statute also says mold remediation "may not be work that requires a license under chapter 489 unless performed by a person who is licensed under that chapter." Chapter 489 covers construction contracting, so rebuild work after demolition may need a licensed contractor too.
What Collier County says about drywall
Removing wet or damaged drywall after a storm
Collier County's Post-Hurricane Information page says: "For the clean up and removal of wet drywall, cabinets, carpeting, and baseboards, permits will not be required." It also asks owners to keep demolition to the minimum needed so it doesn't hurt rebuilding under FEMA guidelines.
Putting it back
The same page says that for residential work "A building permit is required for all repair, replacement and rebuild work." In other words, tear-out and rebuild are treated differently. Plan for a permit on the rebuild side.
Condos and other multi-family buildings
The county is stricter here: "All commercial and multi-family buildings will require a permit for any work performed." That includes condos. Your association will likely have its own rules for contractors as well. See our condo and HOA mold page for more.
The 64 sq ft drywall exemption
Outside of storm recovery, Collier County has a standing exemption under Sec. 22-26 and Florida Building Code 105.2 for "Drywall repair/replacement that are not fire-related and are small areas that do not exceed two sheets of drywall (64 sq. ft.)." A 4 ft by 8 ft sheet is 32 square feet, so two sheets is the limit.
Keep in mind that the permit exemption and the mold license threshold use different numbers. A drywall patch can be small enough to skip a permit (64 sq ft or less) while the mold work behind it is still larger than 10 square feet, the point where Florida's mold licensing law applies.
The new under-$7,500 exemption (July 1, 2026)
Collier County says that "Beginning July 1st, 2026, certain qualifying work valued under $7500.00 will be exempt from building permits." The county's limits are specific:
- Single-family detached homes only, so condos and other multi-family buildings don't qualify.
- The property may not be in a flood hazard area.
- No structural, mechanical, electrical, plumbing or gas work.
- Work may not be split up to stay under the limit.
- You need a written exemption request and an approved letter from the county.
Many mold-related repairs involve plumbing leaks or AC equipment, and many Naples-area homes sit in flood hazard areas, so read the conditions carefully before assuming your project qualifies.
What about the City of Naples and Marco Island?
The City of Naples has its own Building Department, reachable at 239-213-5020, and Marco Island is also its own city. We haven't confirmed whether their drywall exemptions match the county's, so call the city before you start. If your home is in a flood hazard area, ask about the substantial-damage rule as well. Our guide to the 50% rule in Naples and Collier covers that.
Who to call to confirm
For unincorporated Collier County, you can reach the county through Collier 311 at 239-252-4311 and ask for Building Plan Review & Inspection. Have these details ready:
- Your address and whether it's a single-family home or a multi-family building.
- Whether the property is in a flood hazard area (Collier's simplified map is at collier.gov/floodmap).
- The cause of the damage and the size of the area to be removed and replaced.
- Whether any plumbing, electrical, HVAC or framing work is involved.
- The estimated value of the rebuild.
A typical sequence for moldy drywall
Find the moisture source
EPA says "if you clean up the mold, but don't fix the water problem, then, most likely, the mold problem will come back." Fix the leak first.
Size up the area
EPA says homeowners can usually handle a moldy area of "less than about 10 square feet." Above that, Florida law requires licensed professionals.
Get an independent assessment
A licensed assessor documents the moisture and writes a scope. Under s. 468.8419, the assessor and remediator are typically separate companies, except Division I certified contractors under the statute.
Remediation
During remediation, crews typically set up containment, remove affected drywall and insulation, clean and dry the framing and prepare the area for clearance. See our process page.
Permit and rebuild
Pull any required permit for the replacement drywall and related trades, then close up the wall once the area has passed clearance.
Typical cost ranges
Typical national ranges from cost guides (2025–2026, not quotes): a small area of about 50 sq ft runs $500–$1,500, a medium area of 100–200 sq ft $1,000–$6,000, and the per-square-foot range is $10–$30 of affected area. Remediation quotes may not include inspection or clearance testing, and they usually don't include permit fees or rebuild work. The real price comes from a licensed pro's on-site assessment. See our cost guide and mold removal page.
