I would call your area or state licensing departments. I would imagine that would be similar to a general contractor which is not required to have a license in TX. Specialized crafts like plumbing, electrical, etc are required though. Of course you would need to dispose of the items properly.
Not sure in your region. Every city has different rules and regulations. I assume it will only take a business license and bond along with a connection to many property management company and Sheriff's Department.
