Executive summary
A building permit rarely involves one reviewer. Planning, fire, engineering, water and wastewater, transportation and sometimes conservation authorities each hold a piece of the answer, and each works from the same submission for a different purpose.
When those reviews are serialised, elapsed time multiplies. When they run in parallel without a shared record, applicants receive contradictory comments. The design problem is coordination, not review capacity.
Why coordination dominates elapsed time
Serial routing means every wait is additive: the file sits in each queue in turn, and a deficiency discovered late restarts part of the chain. Parallel routing removes the additive wait but introduces a new requirement — someone must reconcile positions before comments reach the applicant.
Federal work on approval efficiency in the infrastructure sector and CMHC’s municipal action-plan material both treat inter-departmental process as part of the approval problem rather than an internal detail [1][2].
A coordinated review model
Three elements make this work: one submission record all departments read, a defined reconciliation step with an owner, and a single outbound response. Without the third, the applicant becomes the integrator.
Handling conflicting positions
| Conflict type | Example | Resolution mechanism |
|---|---|---|
| Requirement overlap | Two departments comment on the same element with different expectations | Named lead per element; other departments comment through the lead |
| Sequencing dependency | A planning condition changes a dimension that building already reviewed | Hold building sign-off until dependent conditions are settled |
| Different information needs | Each department requests a different supporting study | Consolidated information request issued once |
| Interpretation difference | Departments read a local policy differently | Escalation to a documented interpretation, then publish it |
| Timing mismatch | One department reviews only at set intervals | Published service targets per department with visible queue position |
Implications for authorities having jurisdiction
Name a coordinator role with authority to convene, not merely to forward files. Publish per-department service targets, and measure the reconciliation step separately — it is often where files sit longest and it is invisible in start-to-issue metrics.
Where interpretations differ, write the resolution down. An unpublished interpretation resolves one file and repeats the argument on the next.
Implications for applicants and professionals
A consolidated response allows a single coordinated resubmission rather than sequential partial fixes. For applicants, that is usually the largest available reduction in elapsed time, and it depends on the municipality’s process rather than on the design.
Applicants can help by submitting discipline-complete packages with consistent sheet identifiers, so departments are demonstrably reading the same document set.
Risks, limitations and safeguards
- Parallel routing without reconciliation produces contradictory comments and erodes trust faster than slow serial review.
- A coordinator without authority becomes a message relay and adds a queue.
- Shared records raise access-control questions; department-appropriate views are required.
- Service targets per department can encourage premature comments; pair them with quality measures.
- Coordination cannot resolve genuine policy conflict; that needs a decision at a higher level, documented.
PermitAssure perspective
PermitAssure holds one application record with role-based views, so each department reviews the same submission and revision while seeing what is relevant to it. Findings carry their department, evidence and rule reference, and the consolidation step produces a single response record for the applicant.
Five key takeaways
- Serial routing makes waits additive; parallel routing requires an explicit reconciliation step.
- One shared submission record and one outbound response are the core design choices.
- Name a coordinator with authority to convene and resolve, not merely to forward.
- Measure reconciliation time separately; it hides inside start-to-issue metrics.
- Write down interpretations once they are resolved, then publish them.
