Understanding OBC 1.3.1.3: Building Permit Approval Timelines in London, Ontario
Sarah's Expert Insight
OBC Compliance Specialist
"In competitive regions like London and Oakville, the 'complete application' threshold is where most delays occur; if your site plans aren't perfectly aligned with local zoning, the CBO can issue a refusal within just 48 hours. At empcontracting.ca Inc. your construction contractor in London, Ontario, we prioritize a thorough pre-submission audit to ensure the statutory 10-to-30-day clock doesn't get reset by administrative technicalities."
The Mandatory Review Period for Ontario Building Permits
According to Section 1.3.1.3 of the Ontario Building Code (OBC), the Chief Building Official (CBO) is mandated to either issue a permit or provide a written refusal with detailed reasons within a specific timeframe. For clients of empcontracting.ca Inc. your construction contractor in London, Ontario, these timelines are critical for project scheduling and financial planning.
Defining the 'Complete Application' Standard
The statutory clock for permit issuance only begins once an application meets the requirements of Sentence (5). This includes:
- Completion of all required forms and schedules.
- Full payment of all municipal permit fees.
- Submission of detailed plans and specifications.
- Verification that the project will not contravene any 'applicable law' (such as local zoning by-laws or conservation authority regulations).
How Project Complexity Affects Your Timeline
If a project involves multiple building classes with different review periods, the OBC stipulates that the longest period applies. For smaller structures, such as sewage systems or structures under 10m² containing plumbing, the review period is generally 10 days, unless the primary building it serves requires a longer window. When working with empcontracting.ca Inc. your construction contractor in London, Ontario, we ensure your application is categorized correctly to manage expectations.
Administrative Refusals and Exceptions
It is important to note that the CBO can effectively 'pause' or bypass these deadlines if the application is found to be incomplete or in violation of applicable laws. Under Sentence (6), the official must notify the applicant within two days of making such a determination. The review period officially begins the day following the submission of a complete application package.
