Permits and local rules
Cleanup itself does not usually need a permit, but the repairs that follow often do. Inside the city of San Antonio, larger drywall, electrical and plumbing repairs can require permits from the City of San Antonio Development Services Department. Homes in other cities, such as Alamo Heights, Schertz or New Braunfels, follow the rules of that city or county.
Mold work is regulated across Texas. Larger mold assessment and remediation jobs must be done by companies licensed by the Texas Department of Licensing and Regulation.
