Also, a plumber's license is not required to perform work on buildings whose primary use is agricultural and is located outside the incorporated limits of any city or town unless the building is connected to a public water system, sewage system, or gas utility system. Plumbers licensing covers natural gas installation, but does not cover Liquefied Petroleum gas. Arkansas publishes its own plumbing code and has adopted a modified version of the 1994 Standard Gas Code. Inspections are required on all plumbing installations. Inspection fees depend on the number of fixtures and the number of trips made by the inspector.
Cities do inspect plumbing systems that are connected to their public water systems.
Plan review turnover times are 24 to 48 hours depending on the size of the project. There are presently no reciprocal agreements with other states for plumbers licensing in Arkansas.
