Building Permit Timelines: What the Published Number Leaves Out

A published permit turnaround number can be useful. It is not a promise for your project.

The number may describe only an initial review, only agency working time, or only permits that reached a particular milestone during a reporting period. It may exclude the days an applicant spends answering comments, revising drawings, paying fees or waiting for another agency.

The practical question is not simply, “How many days does a permit take?” It is: Which clock is this number measuring, for which kind of permit, and what can stop that clock?

A permit is a sequence of clocks

1. Application and intake. The agency receives the application, creates the record and checks whether required materials are present.
2. Prescreening or completeness review. Staff may identify missing forms, drawings or basic information before full technical review begins.
3. Plan review. One or more groups review the project. Zoning, structural, life-safety, transportation, utilities or other disciplines may work in parallel or in sequence.
4. Corrections. The agency returns comments. The applicant and design team revise the documents and resubmit them.
5. Re-review. Reviewers check the response. Another correction cycle may follow.
6. Approved-to-issue. Technical review may be complete even though fees, contractor information or other administrative steps remain.
7. Issuance and construction. The permit is issued, but the project still needs scheduled inspections and final approval.

A dashboard that measures plan review is not reporting the whole elapsed time from application to final inspection.

Agency time and applicant time are different

Portland’s published permit materials are a useful example because the city describes multiple permit stages and correction steps. Its correction instructions note that different review groups may examine a permit and that the applicant submits corrections after the applicable reviews are complete.

That matters because a single elapsed-time figure can combine two fundamentally different intervals: time the application is waiting for or receiving agency review, and time the applicant, architect, engineer or contractor is preparing a response.

Some dashboards pause the measured agency clock during applicant response time. Others report calendar time or a broader elapsed period. Unless the methodology says which approach is used, two numbers that look comparable may not be comparable at all.

Initial review is not total approval time

“First review,” “initial review” and “first comments” usually describe an early milestone. A project can meet an initial-review target and still require multiple correction cycles before issuance.

Before using a published number for scheduling, look for the exact endpoint:

• first review completed;
• first set of comments issued;
• all technical reviews approved;
• approved to issue;
• permit issued; or
• final inspection completed.

A number ending at first comments should never be presented as the total time to an issued permit.

Median and average answer different questions

The average adds all measured durations and divides by the number of permits. A small number of unusually long projects can pull it upward.

The median is the middle result when durations are ordered. It is less affected by extreme cases, but it still does not tell you the range or the likelihood that a complex project will take longer.

Neither measure predicts an individual project. To understand variability, look for a distribution, percentile, range or count of projects—not just one center value.

The cohort matters

A useful timeline must identify which permits were included. Turnaround can vary with permit type, scope, complexity, completeness, additional reviews, correction cycles, reporting period, staffing and workload.

Portland’s permit-timeline page, for example, separates project types and explains that project valuation and scope can affect review and inspection effort. Its permitting-metrics materials frame the dashboards as measures of outcomes and improvement, not guarantees for a specific application.

What the applicant can control

Submit a complete package

Use the current checklist for the exact permit type. Confirm forms, drawings, calculations, signatures and supporting documents before submission.

Keep scope consistent

A material scope change can trigger new drawings, additional review disciplines or a revised valuation. Record decisions before the application when possible.

Track every review group

A permit can wait because one discipline is unresolved even when others are approved. Use the agency portal or status report to identify the open review.

Respond to the full correction set

A partial response can create another cycle. Use a response letter or comment matrix that shows where each issue was addressed.

Complete issuance steps promptly

“Approved” and “issued” are not always the same status. Check for outstanding fees, contractor information or other administrative requirements.

How to use a dashboard responsibly

1. Confirm the jurisdiction and permit type.
2. Read the metric definition and reporting period.
3. Identify the start and end milestones.
4. Determine whether applicant time is included.
5. Check whether the measure is median, average, percentile or target.
6. Compare your project with the reported cohort.
7. Add time for corrections, issuance steps and inspections.
8. Recheck the dashboard immediately before committing to a schedule.

For a project that changes an electrical service or panel, the distinction between equipment work and utility/service work also affects coordination. ClearTrade’s guide to panel replacement versus service upgrade explains why those are not the same project.

A better question to ask the permitting office

For this permit type and scope, what is the current time to first review, what commonly triggers corrections, and which additional reviews or issuance steps should I include in the schedule?

Frequently asked questions

Does the permit timeline include corrections?

Sometimes. The dashboard methodology should say whether applicant-response time is included, excluded or paused. Do not assume.

Is a median permit time the same as a service target?

No. A median summarizes completed records in a defined cohort. A target is an operational goal. Neither guarantees an individual result.

Does “approved” mean I can start work?

Not necessarily. Some systems distinguish plan approval, approved-to-issue and permit issuance. Follow the jurisdiction’s status definitions and do not start regulated work until the required authorization is issued.

Can a contractor guarantee a permit date?

A contractor can manage application quality and response time, but normally cannot guarantee agency review or approval timing.
