Wind
ASCE 7 basic wind speed: typically 115 mph ultimate design wind speed for Risk Category II buildings in Franklin County, subject to exposure category and site-specific conditions.
Snow Load
Ground snow load: typically about 20 psf in the Columbus area, with roof snow loads calculated under the adopted Ohio Building Code/ASCE 7 based on exposure, thermal condition, importance, and roof geometry.
Flood
Columbus participates in the National Flood Insurance Program, and floodplain requirements are based on FEMA Flood Insurance Rate Maps. Properties near the Scioto River, Olentangy River, Big Walnut Creek, Alum Creek, and other drainage corridors may be in Special Flood Hazard Areas requiring elevation certificates, flood-resistant materials, lowest-floor elevation standards, and floodplain development permits.
Earthquake
Seismic design is generally low to moderate in central Ohio. Many typical Risk Category II buildings are assigned Seismic Design Category B, but final seismic design category depends on mapped spectral response values, soil site class, occupancy, and structural system.
Wildfire
Columbus has low wildfire risk compared with western U.S. jurisdictions and does not generally apply a separate wildland-urban interface code for typical urban projects. Properties near wooded ravines, parks, or large vegetated areas may still need defensible access, fire apparatus access, and vegetation or fire safety measures under local fire and property maintenance requirements.

Approval Timeline
Simple residential trade permits may be issued quickly when no plan review is required. Residential plan review for additions, decks, garages, and remodels commonly takes about 1 to 3 weeks depending on completeness and zoning issues. New homes and larger residential projects often take 2 to 4 weeks. Commercial tenant improvements commonly take 3 to 6 weeks, while new commercial buildings, change-of-use projects, or projects requiring multiple agency reviews can take 6 to 10 weeks or longer. Corrections and resubmittals add time.
Common Requirements
Typical submittals include a completed permit application, owner and contractor information, construction drawings, site plan, scope of work, energy code information, and trade permit details. Residential additions, garages, decks, and accessory structures usually need a plot plan showing property lines, setbacks, easements, lot coverage, and existing structures. Commercial projects usually require code-compliant architectural, structural, mechanical, electrical, plumbing, fire protection, accessibility, and energy drawings. Contractors must be properly registered or licensed where required, and some projects require zoning approval, floodplain review, historic review, fire review, or right-of-way permits.
Zoning Information
Columbus zoning is administered by the Department of Building and Zoning Services. Zoning review verifies that the proposed use, building height, setbacks, lot coverage, parking, signage, accessory structures, and other site standards comply with the Columbus Zoning Code. Properties may be subject to residential, commercial, manufacturing, downtown, university-area, historic, or overlay district standards. Variances, special permits, graphics approvals, and Board of Zoning Adjustment review may be required when a project does not meet zoning requirements.
Permit Costs
Permit fees in Columbus vary by project type, valuation, square footage, and required trade permits. Small residential trade permits may be roughly $75 to $250. Decks, small remodels, garages, and additions often range from a few hundred dollars to $1,000 or more depending on scope. New single-family homes commonly involve several hundred to several thousand dollars in building, plan review, and trade fees. Commercial permits are usually based on valuation and can range from several hundred dollars for minor tenant work to many thousands of dollars for larger projects, plus separate electrical, mechanical, plumbing, fire, zoning, and inspection fees.
Engineering Requirements
Engineer or architect seals are typically required for commercial buildings and for drawings governed by the Ohio Building Code. Residential projects under the Residential Code of Ohio may not always require sealed drawings, but engineered design is commonly needed for non-prescriptive structural work, unusual foundations, retaining walls, long-span beams, steel framing, complex decks, major structural alterations, manufactured trusses, tall accessory structures, and work involving flood-resistant design. Commercial structural, mechanical, electrical, plumbing, fire protection, and energy systems generally require design by Ohio-licensed professionals where required by state law.
Local Code Adoption
Columbus enforces the Ohio Building Code, Ohio Mechanical Code, Ohio Plumbing Code, Ohio Fire Code, Ohio Energy Code, and the Residential Code of Ohio as adopted by the Ohio Board of Building Standards. Ohio’s current statewide codes are based largely on the 2021 I-Codes with Ohio amendments, including the 2024 Ohio Building Code and 2024 Residential Code of Ohio.
