A plans examiner reviews plans, often submitted by construction companies or architects applying to receive work permits, to ensure that those plans meet building codes and requirements of the state, county, and city where the construction is taking place. As a plans examiner, you look at blueprints for both residential and commercial properties. Your specific duties and responsibilities are to evaluate zoning compliance, work with architects, builders, and homeowners to obtain compliance, make recommendations for whether or not to issue permits, and sometimes supervise individuals who research codes and zoning ordinances.
