Do you need a permit for mold remediation in McKinney, TX?
It depends
It depends on scope. Like-for-like cosmetic work in McKinney is often exempt, but a permit is required as soon as you change structure, plumbing, electrical or the building envelope.
McKinney sits in Collin County, Texas. Hail and high straight-line winds are the dominant loss driver, so impact-rated roofing and insurance-funded replacement shape local pricing. Work outside city limits is permitted by the county building department rather than the city.

Frequently asked questions
Does Florida license mold remediation?
Yes. Florida requires separate licenses for mold assessors and mold remediators, and with limited exceptions the same company cannot both assess and remediate the same property — which protects you from inflated scope.
