It is the duty of the building official, or other authority charged with the duty of issuing building or similar permits, of any incorporated municipality or subdivision of the municipality or county to refuse to issue a permit for any undertaking which would classify the applicant as a residential builder or residential specialty contractor under the provisions of this chapter unless the applicant has furnished evidence that he is either licensed or registered as required by this chapter or exempt from the requirements of this chapter. It is also the duty of the building official, or other authority charged with the duty of issuing building or similar permits, to report to the state licensing board the name and address of any person who, in his opinion, has violated this chapter by accepting or contracting to accomplish work which would classify the person as a residential builder or residential specialty contractor under the provisions of this chapter.
