After you submit your permit application and pay fees, the plan review clock starts ticking. Ohio law gives Columbus up to 30 business days for initial review, and they typically use most of it. Here’s how to work within that timeline and avoid extending it unnecessarily.
Initial Review Period: 30 Business Days
By law, Columbus must provide initial plan review comments within 30 business days of a complete submission. In practice:
Simple projects: Often reviewed in 3-4 weeks
Complex projects: May take the full 6 weeks
Backlogs: Can push simple projects to the full timeline
Plan for 6 weeks in your project schedule. If you get it back sooner, great. If not, you’re not behind schedule.
Review Team Structure
Your plans get reviewed by multiple specialists simultaneously:
- Building/Structural: General code compliance, structural elements, life safety
- Mechanical: HVAC systems, ventilation, energy code
- Electrical: Power, lighting, fire alarm systemsÂ
- Plumbing: Water supply, drainage, fixtures
- Zoning: Site compliance, use verification
- Fire/Life Safety: Egress, fire protection systems
Each group works on their own timeline, and their comments may not come in at the same time. One department can hold up the whole process if their review isn’t closed out.
Three Possible Outcomes
After initial review, you’ll get one of these responses:
- Full Approval (Rare)
Everything meets code and zoning requirements. Permit is ready for issuance. This happens on maybe 5% of first submissions. - Conditional Approval
Minor issues that can be resolved during construction or with simple clarifications. Close to full approval. - Plans Rejected with Corrections (Most Common)
Issues that require plan revisions before approval. This is normal – expect at least one round of comments on most projects.
Handling Plan Review Comments
When you get comments, act fast and be thorough:
- Read everything carefully. Comments can range from minor clarifications to significant design changes.
- Ask questions if unclear. Columbus reviewers are generally helpful if you call or email for clarification.
- Address ALL comments in your resubmission. Don’t cherry-pick the easy ones and hope the rest go away.
- Submit complete revisions. Half-finished corrections just generate another comment cycle.
Resubmission Timeline
Minor corrections: Often approved within a few days to a week
Substantial revisions: Can take another 1-2 weeks
Resubmissions typically get faster review since only the corrections are being checked. But if you make major changes beyond what was commented on, you might trigger a fuller re-review.
Expedited Review Options
After Hours Review
Columbus offers plan review by appointment outside normal business hours for an extra fee. This can significantly cut review time if you coordinate it properly.
Phased Permits
For large projects, you can get foundation permits reviewed faster since they’re a smaller subset of plans. This lets site work start while the full building is still under review.
State Review
Ohio’s Building Department offers expedited review (as little as 2 hours) for extra cost, but since Columbus is certified to do its own reviews, you’d typically work through them instead.
Managing Multiple Review Cycles
- First round comments: Plan for this in your schedule
- Second round: Should be minimal if you addressed everything properly
- Third round or more: Sign that either your design has issues or your responses aren’t complete
If you’re hitting multiple comment cycles, consider requesting a meeting with the plans examiner to make sure you understand what they need.
External Approvals
Run these parallel to building plan review:
- Health Department: If you have any food service areas
- Public Utilities: Water/sewer connection approvals
- Historic Commission: If in a historic district
- Board of Zoning Adjustment: If you needed a variance
Building permits won’t be issued until all required pre-approvals are satisfied.
Pro Tips for Faster Reviews
- Submit complete packages: Missing information just generates standard “provide missing item” comments
- Use experienced professionals: Architects and engineers familiar with Columbus codes produce cleaner initial submissions
- Pre-submission meetings: For complex projects, consider meeting with reviewers before formal submission
- Respond quickly: Fast response to comments keeps your project moving through subsequent review cycles
Common Delay Causes
- Incomplete responses to comments: Addressing some but not all issues
- Design changes during review: Major modifications that require re-review
- Missing outside approvals: Waiting for zoning variances or utility approvals
- Contractor licensing issues: Unlicensed contractors can’t pull permits
Approval and Permit Issuance
Once all reviews are approved:
- Department of Building and Zoning Services (BZS) finalizes the permit
- You get email notification that documents are ready
- Download approved plans and approval letter from portal
- Pay any remaining permit fees
- Permit status changes to issued/active
- Construction can begin
Keep approved stamped plans on the job site during construction – inspectors will reference them.
Managing Expectations
A plan review isn’t a bureaucratic hurdle, reviewers are ensuring your project meets code and will be safe for occupants. Work with the process rather than against it, and you’ll get better results in less time.
Budget 6-10 weeks for plan review in your project schedule. If you beat that timeline, you’re ahead of schedule. If not, you’ve planned appropriately and aren’t scrambling to make up time.
