Licenses are required for every person transacting and carrying on the business of contracting in any occupation (plumbers, electricians, carpenters, painters and the like) on any scale, including subcontracting. An "owner/builder" is a person who acts as or employs a contractor, subcontractor, specialty contractor or workers under his supervision and direction by the hour or day, for the purpose of constructing improvements on real property owned by him within the city. He shall pay the same fees as a general builder contractor unless his only activity is construction on his property which is not offered or intended for sale within one year from date of completion.
