Building Permits in Columbus

Columbus requires a building permit for most construction, alteration, repair, and demolition work that affects structural, electrical, plumbing, or mechanical systems. Permits are issued by the Columbus Department of Building and Zoning Services (BZS), which also conducts plan reviews and field inspections to enforce state and local building and zoning codes.

Columbus enforces the Ohio Building Code (OBC) — a statewide code administered by the Ohio Board of Building Standards, based on the 2021 International Building Code (IBC) with Ohio amendments, effective March 1, 2024. Residential construction for one-, two-, and three-family dwellings falls under the Residential Code of Ohio (RCO), which is based on the 2021 International Residential Code (IRC). Ohio's statewide code framework means that BZS enforces state-adopted standards rather than a purely locally-written code.

When You Need a Permit

You generally need a Columbus building permit for:

• New construction, additions, and accessory structures including ADUs (Accessory Dwelling Units)
• Structural alterations, load-bearing wall changes, and foundation work
• Electrical, plumbing, and mechanical (HVAC, gas piping, fireplaces) changes
• Reroofing and window or door openings in exterior walls
• Decks, porches, and most swimming pools or hot tubs
• Fences taller than 6 feet
• Detached sheds and accessory structures 200 square feet or larger
• Retaining walls more than 4 feet high (measured from bottom of footing)
• Demolition of any habitable structure

Common exemptions include fences 6 feet or shorter, sheds under 200 square feet, retaining walls 4 feet or lower, and minor cosmetic work (painting, floor coverings, cabinetry without plumbing or electrical changes). When in doubt, contact BZS before starting work.

Citizen Access Portal — The Online Portal

The Columbus Citizen Access Portal (powered by Accela) is the primary online system for BZS services, available at portal.columbus.gov/permits. The portal is accessible 24 hours a day, 7 days a week.

Through the Citizen Access Portal you can:

• Create a personal or business account
• Submit new building, engineering, and zoning applications
• Upload plans for electronic plan review
• Respond to correction comments without visiting the BZS office
• Purchase permits and inspection trips online
• Schedule and track inspections
• Search existing permit and application records

Permits are organized into three sections in the portal: Building, Engineering, and Zoning. For technical assistance, contact BZS at (614) 645-7433 or visit 111 N. Front Street, Columbus, OH 43215, weekdays 9 a.m.–4 p.m.

Permit Costs

Columbus permit fees are established in the Combined Development Related Fee Schedule, updated periodically by BZS (the current schedule is effective January 22, 2026). Fees vary by project type and are calculated based on:

• Permit fee — may be based on project valuation, gross square footage of construction area, or a flat rate depending on permit type
• Plan review fee — charged for projects requiring plan check before permit issuance
• Inspection trips — a base number of inspections is typically included with a permit; additional trips can be purchased if needed
• Trade permit fees — separate permits (and fees) for electrical, mechanical, and plumbing work

Always refer to the current Columbus BZS Fee Schedule linked in the sources above for exact amounts. Fees are due and payable at time of submission.

Typical Timeline

BZS offers an expedited after-hours plan review service for applicants needing faster turnaround on projects requiring building, mechanical, electrical, and plumbing plan review. Contact BZS for current expedited review availability and fees.

The Process

1. Pre-submittal: Confirm your property's zoning, applicable codes, and whether plan review is required for your project type
2. Plans: Prepare drawings and construction documents meeting the OBC/RCO requirements; an architect or engineer stamp is required for many projects
3. Submit via Citizen Access Portal: Upload documents electronically and pay any applicable fees
4. Plan review: BZS reviews plans for compliance across relevant disciplines (building/structural, electrical, mechanical, plumbing, zoning, fire)
5. Corrections: If correction comments are issued, revise plans and resubmit through the portal
6. Permit issuance: Pay remaining fees and receive your permit
7. Post permit card: The permit card must be visible at the job site during construction
8. Inspections: Schedule required inspections at each construction phase through the Citizen Access Portal or by phone
9. Final: Pass the final inspection; a Certificate of Occupancy is issued for applicable projects before occupancy

Inspections

BZS conducts inspections across four disciplines: Electrical, Mechanical, Plumbing, and Structural. Separate permits are required for each trade, and inspections validate that work matches the approved permit and plans. All required inspections must be approved before a permit can be closed.

Typical inspection stages for a residential project include:

• Footing / foundation
• Underground plumbing and electrical
• Rough framing (structural)
• Rough plumbing, electrical, and mechanical
• Insulation
• Drywall
• Final building and trade inspections

Schedule inspections through the Columbus Citizen Access Portal at portal.columbus.gov/permits or by calling BZS at (614) 645-7433. Before a permit can be completed and closed, all required inspections must receive approval.

Common Reasons for Denial or Corrections

• Plans do not meet the Ohio Building Code (OBC) or Residential Code of Ohio (RCO)
• Missing or insufficient structural calculations, energy compliance documentation, or design-professional stamps
• Zoning conflicts — setbacks, height limits, lot coverage, or use not permitted in the zoning district
• Incomplete submittal or missing documents in the Citizen Access Portal
• Missing utility or site engineering clearances (water, sewer, stormwater, right-of-way)
• Historic preservation district or overlay zone review not completed
• Contractor not licensed or registered with BZS
