What are Letters of Assurance?
Letters of Assurance are legal accountability documents that are required under the BC Building Code (BCBC), intended to clearly identify the responsibilities of the key players in a construction project. Uniform, mandatory Letters of Assurance have been included as Schedules (see below) in the BCBC since December 1992.
The BCBC requires Letters of Assurance in specific instances to document the parties responsible for the design and field review of construction, and to obtain their professional assurances that the work substantially complies with the requirements of the BCBC, except for construction safety aspects, and that the required field reviews have been complete.
Schedule A: Confirmation of Commitment by Owners and Coordinating Registered Professional.
- This assurance by the owner and the coordinating registered professional must be submitted to the Regional District before issuance of a building permit
Schedule B: Assurance of Professional Design and Commitment for Field Review & Summary of Design and Field Review Requirements.
- The Schedule B for each registered professional of record retained on the project must be submitted to the Regional District prior to the commencement of construction activities of the components identified
- Schedule B confirms that the registered professional of record signing and sealing it will be responsible for the design and field review within the discipline which he or she has initialled.
Schedule C-A: Assurance of Coordination of Professional Field Review.
- A schedule C-A must be submitted by the coordinating registered professional after completion of the project but before an occupancy permit is issued or a final inspection is made by the Regional District.
Schedule C-B: Assurance of Professiona Field Review and Compliance.
- A separate Schedule C-B must be completed for each Schedule B and submitted to the Regional District after completion of the project but before the Regional District issues an occupancy permit or makes a final inspection.
For information on whether or not your project will require Letters of Assurance, please contact the Regional District building inspector.
