Audits

Audit Process & Requirements

To maintain quality control, audits will be conducted on each subdivision participating in the Volume Builder Program. The number of lots audited will be determined by calculating 5% of the total lots a builder is developing.

• Volume Builder permit applications will be selected at random for audit.
• Each audit will review compliance at the individual permit level, ensuring that the plans and documentation submitted match the approved Master Plan, including the Zoning Review Sheet (ZRS), application, and construction documents.

Audit Outcomes

Audits will result in either a Pass or Fail classification:

• Minor Failures – Small errors such as typos, missing sheets, or other issues that do not affect the structure. Builders will be required to correct these issues, but they will not immediately impact participation in the program.
• Major Failures – Occur when there are modifications to an approved prototype, the use of a non-approved prototype within a subdivision, or applications submitted for a subdivision that has not been approved. If audit failures exceed 5% of dwelling units within a calendar year (up to 10 findings), the builder’s registration in the program may be canceled for the remainder of the year.

If a builder’s registration is canceled due to non-compliance with the program, they may still submit applications through the Residential Plan Review Standard process.

Program Reinstatement

• Builders removed from the program due to excessive failures may reapply starting January 1st of the following year.
• To rejoin, the builder must attend a reinstatement meeting to confirm understanding of the program's compliance requirements.
• If the builder chooses not to rejoin, they may proceed through the Residential Intake Process, which requires a 15-day review for individual permit approvals.

For additional information, refer to the Building Criteria Manual (BCM).
