Local rules & permits
Restoration contractors must be licensed by AZ ROC
The Arizona Registrar of Contractors (AZ ROC) licenses and regulates residential and commercial contractors statewide and investigates complaints against both licensed and unlicensed operators. Repair, remodeling and structural restoration work generally requires the appropriate ROC license classification. Arizona does not issue a separate mold-remediation license, so mold work is regulated through the general contractor-licensing framework rather than a mold-specific credential; homeowners can verify a license and complaint history on the ROC website.
