Permit Requirements in Winona
Know when you need a permit to ensure your project is legal and safe
General Rules
In Winona and Smith County, permits are typically tied to the construction or repair work that happens alongside mold remediation — not the mold cleaning itself. If your remediation involves removing drywall, replacing structural lumber, cutting into ductwork, or making electrical or plumbing modifications, a building permit is often required. The City of Winona and Smith County enforce the International Building Code and International Residential Code, which govern structural and mechanical repairs. Always check with the local building official to confirm if your specific scope of work requires a permit.
When Permits Are Required
Permits may be required when mold remediation involves:
- Structural repairs — replacing studs, joists, sheathing, or subflooring damaged by mold
- Drywall removal and replacement beyond small patchwork (typically over 32 square feet)
- HVAC system modifications — cleaning or replacing ductwork, duct board, or air handlers affected by mold
- Electrical work — rewiring or replacing outlets, switches, or fixtures in mold-damaged areas
- Plumbing work — repairing leaks or replacing pipes that contributed to moisture issues
- Demolition — removing walls, ceilings, or built-in structures to access mold
- New construction or additions — if remediation is part of a larger renovation project
Common Exemptions
Permits are typically not required for:
- Small-scale surface mold cleaning using store-bought products (less than 10 square feet)
- Routine maintenance like fixing a minor leak that hasn't caused structural damage
- Mold assessment or testing alone (no physical alteration of the building)
- Cosmetic repairs such as repainting primed surfaces after minor mold removal
Important: Even if a permit isn't required for the mold work itself, any associated repair work (electrical, plumbing, structural) may still trigger permit requirements. When in doubt, it's always best to ask local authorities.

Permit Process
Step 1: Determine the Scope of Work
Have a licensed mold assessment professional or contractor evaluate the extent of mold damage. This will help you understand whether structural repairs or system modifications are needed — and whether a permit is likely required.
Step 2: Contact the Winona or Smith County Building Department
Reach out to the local building official to discuss your project. Share the scope of work and ask whether a building permit or any specialty permits (electrical, mechanical, plumbing) are required. Be prepared to describe the extent of demolition and repairs.
Step 3: Prepare and Submit Permit Application
If a permit is needed, you'll typically submit an application along with a scope of work description. For larger structural repairs, you may need to provide drawings or plans. A licensed contractor familiar with local codes can help prepare these documents.
Step 4: Schedule Inspections
Once work begins, inspections may be required at key stages — such as after demolition but before new drywall is installed, or after structural repairs are completed. Inspections ensure the work meets safety and building code standards.
Step 5: Final Approval and Closeout
After all work is completed and passing final inspection, the permit is closed out. This documentation can be valuable for future property sales and insurance purposes, showing that mold remediation and repairs were done correctly and to code.
Compliance Tips
- ✓ Always get a written scope of work from a licensed professional before deciding whether a permit is needed.
- ✓ Don't assume small mold jobs don't need a permit — if repairs go beyond surface cleaning, ask local authorities first.
- ✓ Use contractors who are familiar with Smith County and Winona building codes; unpermitted work can complicate future home sales.
- ✓ Keep all permits, inspection reports, and remediation documentation on file — they're valuable for insurance claims and property disclosures.
- ✓ If mold was caused by a plumbing leak or storm damage, check with your insurance provider — they may require permitted repairs for coverage.
- ✓ Plan for inspections: don't cover up repaired areas (like new drywall or insulation) until the required inspection has passed.
Special Considerations
HOA Rules
If you live in a Winona neighborhood governed by a Homeowners Association (HOA), check your CC&Rs before starting mold remediation work that alters the exterior appearance of your home — such as replacing siding, windows, or roofing affected by mold. Some HOAs require prior approval for exterior repairs or dumpster placement during remediation. HOA rules are separate from city permits, so you may need both.
Zoning
Zoning regulations in Winona primarily affect commercial or multi-family mold remediation projects. If you're remediating a business property, verify that the work complies with local zoning ordinances, especially if it involves changes to building size, use, or occupancy. Residential single-family homes typically have fewer zoning hurdles for interior mold work.
Historic Properties
Winona has historic properties that may fall under local or state historic preservation guidelines. If your property is listed on or eligible for the National Register of Historic Places, or is in a designated historic district, additional review may be needed before making repairs. Mold remediation on historic structures often requires special care to preserve original materials. Check with the Winona or Smith County planning office for guidance.
