Building codes ARE administered by insurance companies. The insurance industry is the main reason we have building codes. The organizations that maintain the codes (e.g. the National Fire Prevention Association which maintains the National Electric Code) is a nonprofit, non-governmental organization made up of people from the insurance and construction industries. These codes are then adopted into law by various municipalities, possibly with amendments. The government itself doesn't write the code though.
