Permit Requirements in Marietta
Know when you need a permit to ensure your project is legal and safe
General Rules
In Marietta and Cass County, permits are typically required when mold remediation involves more than surface cleaning. Any work that alters the structure of a building, replaces drywall, removes framing, or modifies mechanical systems (HVAC, ductwork, plumbing) is likely subject to permitting requirements.
Texas does not have a statewide mold remediation license, but local municipalities often adopt the International Building Code (IBC) and International Residential Code (IRC), which govern repair and renovation work triggered by mold damage.
When Permits Are Required
Permits are often required for:
- Structural repairs due to rot or mold damage (replacing studs, joists, subflooring)
- Drywall removal and replacement that exceeds cosmetic repairs
- HVAC system modifications related to mold contamination in ductwork
- Plumbing repairs addressing moisture sources feeding mold growth
- Demolition of interior walls, ceilings, or flooring affected by mold
- Commercial or rental properties where building code enforcement is stricter
Always check with the Cass County building department or Marietta city offices to confirm specific triggers.
Common Exemptions
Small-scale mold remediation may not require a permit if:
- The affected area is less than 10 square feet and involves only surface cleaning
- No structural components (studs, joists, sheathing) need replacement
- The work does not involve electrical, plumbing, or mechanical systems
- The remediation is strictly cosmetic (cleaning non-porous surfaces)
Even if a permit isn't needed, following industry-standard mold remediation protocols is strongly recommended for safety and liability reasons.
✅ Usually Required

Permit Process
Contact Local Authorities
Start by reaching out to the Cass County building department or Marietta municipal offices. Explain the scope of your mold remediation project and ask whether a permit is required. Bring photos and detailed notes about the affected area to get accurate guidance.
Submit Application & Scope of Work
If a permit is needed, you'll submit an application describing the remediation plan. This typically includes a scope of work, details on affected materials, and sometimes a moisture remediation plan. A licensed contractor familiar with local codes can help prepare this documentation.
Schedule Inspections
Once work begins, inspections may be required at key milestones — such as after demolition but before new construction, or after HVAC repairs. Passing inspections confirms the work meets building and safety codes. Your contractor should coordinate inspection scheduling with the county.
Final Approval & Close-Out
After all remediation and repairs are complete, a final inspection may be needed. Once approved, the permit is closed out. This documentation can be valuable for future property sales, insurance claims, and proof of code compliance.
Compliance Tips
- ✓ Hire a licensed contractor who understands Cass County building codes and can pull permits on your behalf.
- ✓ Document everything — photos before, during, and after remediation are critical for compliance and insurance.
- ✓ Never drywall over a mold problem without addressing the moisture source. Permits help ensure this doesn't happen.
- ✓ If your remediation involves a landlord-tenant situation, check lease terms — some leases require professional, permitted remediation.
- ✓ Keep copies of all permits and inspection sign-offs. These documents add value when selling your Marietta home.
- ✓ For large mold infestations (10+ sq ft), even if a permit isn't strictly required, following EPA and IICRC standards is strongly advised.
Special Considerations
HOA Rules
If your Marietta property is within a homeowners association (HOA) jurisdiction, check your CC&Rs before starting mold work. Some HOAs have specific rules about exterior alterations, dumpster placement, or work hours. Get written approval from your HOA if required — this can prevent fines or stop-work orders down the road.
Zoning
Zoning regulations in Cass County can affect mold remediation projects, especially for commercial or multi-family properties. Property setbacks, waste disposal, and noise ordinances may apply. Some zones may restrict outdoor storage of debris or require specific containment measures. Verify with local zoning authorities to avoid violations.
Historic Properties
Marietta has properties that may fall under historic preservation guidelines, particularly if listed on county or state registers. Historic designations can restrict how much material can be removed or replaced. Any structural mold remediation on a historic property may require special review. Consult the Texas Historical Commission and Cass County historical resources before beginning work.
