RRO Annual Renewal

Annual renewal is required in order to maintain the RRO registration. The RRO must maintain activities as a quality assurance observer or perform job duties requiring the skills of a quality assurance observer.

An annual renewal fee is required and 10 building envelope-related continuing educational hours (CEHs) must be earned each year.  All registrants are encouraged to self-report CEHs via the website and upload documentation of attendance.

In the event the RRO discontinues employment in the construction industry or takes employment with a firm that provides services that cause a conflict of interest, the RRO registration will be forfeited. Registration granted by IIBEC shall remain its property.
