Permit Requirements in Markham
Know when you need a permit to ensure your project is legal and safe
General Rules
In Markham and across Matagorda County, building permits are generally not required for the mold remediation process itself (testing, containment, HEPA vacuuming, and removal of contaminated materials). However, permits are often required for the reconstruction and repair work that follows remediation — such as replacing drywall, framing, insulation, electrical work, or HVAC modifications.
When in doubt, always check with the Matagorda County building department or Markham's local permitting authority before starting work.
When Permits Are Required
A building permit may be required when mold remediation involves:
- Structural repairs — Replacing or repairing load-bearing walls, roof sheathing, or floor joists damaged by mold
- Drywall replacement — Large-scale replacement of wallboard (typically over a certain square footage threshold)
- Electrical work — Rewiring or replacing electrical outlets, switches, or panels affected by moisture
- HVAC modifications — Replacing ductwork, air handlers, or HVAC components where mold was found
- Plumbing repairs — Fixing leaks or replacing pipes that caused the moisture issue
- Insulation replacement — Removing and reinstalling insulation in affected areas
Additionally, Texas state law (TDLR rules) requires that anyone performing mold remediation for compensation in a property with over 25 contiguous square feet of mold must hold a TDLR mold remediation license.
Common Exemptions
Permits may not be required in these situations:
- Small, isolated areas — Minor mold cleanup under 10 square feet (e.g., a small patch in a bathroom corner) where no structural repair is needed
- Non-structural surface cleaning — Cleaning mold off non-porous surfaces with detergent and water
- DIY remediation — Homeowners performing their own mold cleanup on their personal residence (though state licensing rules may still apply if hiring help)
- Minor repairs — Small drywall patching that doesn't involve structural changes
Important: Even if a permit isn't required, TDLR licensing rules may still apply if you hire a remediation company. Always verify with local authorities.

Permit Process
Step 1: Determine if a Permit Is Needed
Contact the Matagorda County building department or Markham's local permitting office to discuss your project scope. Provide details about the extent of mold damage and planned repairs. They can tell you exactly which permits, if any, are required.
Step 2: Hire a TDLR-Licensed Mold Remediation Contractor
Texas law requires mold remediators to be licensed by TDLR for projects over 25 contiguous square feet. Choose a contractor who carries proper licensing, insurance, and familiarity with local Markham building codes.
Step 3: Submit Permit Application and Plans
If a permit is needed, your contractor will typically submit the application along with any required documentation — such as scope of work, repair plans, and material specifications. The permitting office will review for code compliance.
Step 4: Schedule Inspections
After the remediation work is complete and reconstruction begins, inspections may be required at key milestones — such as before closing up walls with drywall. Your contractor should coordinate inspection scheduling with the local building department.
Step 5: Obtain Final Approval
Once all work passes inspection, a certificate of completion or final permit sign-off is issued. This documentation is important for property records, insurance purposes, and future home sales.
Compliance Tips
- ✓ Always verify that your mold remediation contractor holds a valid TDLR license — Texas law requires this for projects over 25 contiguous square feet.
- ✓ Get written documentation of all permits, inspections, and approvals. This protects you during property sales and insurance claims.
- ✓ Don't skip the moisture source fix — remediation without addressing the underlying leak or humidity issue will likely lead to mold returning and potential code violations.
- ✓ Ask your contractor if they will handle permit applications and inspection coordination on your behalf — many licensed pros include this in their service.
- ✓ Keep records of all mold testing results, remediation protocols, and post-remediation clearance reports for future reference.
Special Considerations
HOA Rules
If your Markham property is part of a homeowners association (HOA), your HOA may have additional rules regarding mold remediation work. Check your HOA covenants, conditions, and restrictions (CC&Rs) before starting any exterior work or major renovations. Some HOAs require prior approval for visible changes like new siding, roofing, or exterior repairs that follow mold remediation.
Zoning
Zoning regulations in Markham and Matagorda County may affect mold remediation projects, particularly for commercial properties or multi-family dwellings. Setback requirements, property use restrictions, and stormwater management rules could apply if the remediation involves exterior demolition or new construction. Always verify zoning compliance with the local planning department.
Historic Properties
Markham is located in Matagorda County, which may have properties near historic areas or designated landmarks. If your property is located in a historic district or is a designated historic structure, additional review may be required before any exterior alterations or structural repairs can begin.
