Quick answer
Franklin County lists 'Building Deck' outright among the activities that require a building permit, and its Residential Zoning Compliance application separately covers a patio or deck, so a deck project needs both a county building permit and a zoning approval. The Residential Code of Ohio does carve out one narrow case: a deck is exempt from building department approval only if it is no larger than 200 square feet, no more than 30 inches above grade at any point, not attached to the dwelling, and does not serve the required exit door. Even a deck that meets all four conditions still needs the zoning approval, so a permit of some kind is required either way.

How to apply in Franklin County
In Franklin County, a residential deck permit application is a set of construction documents that show what will be built and prove it meets the IRC deck provisions. In practice that means a scaled site plan locating the deck and its setbacks, plus deck plans and structural details covering the footings, posts, beams, joists, ledger, guards, and stairs.
What most deck permit applications include:
- For Franklin County, a permit application identifying the work, the deck's size (square footage), and whether electrical work such as lights or receptacles is included, submitted for plan review before construction begins (IRC R106).
- For Franklin County, a scaled site plan (for example 1/4 inch to 1 foot) showing the new deck's location relative to the house, its overall length and width, and dimensioned distances from the deck to all property lines and other structures so required setbacks can be verified (IRC R106.1.1).
- For Franklin County, a deck plan drawn to scale showing overall dimensions and the framing layout: joist size, spacing, span, and species; beam size and span; post size and height; and footing or pier size and depth (IRC R507.4 posts, R507.5 beams, R507.6 joists, R507.3 footings).
- For Franklin County, a section or side elevation with connection details showing the ledger attachment to the house band joist with flashing, the fastener or bolt schedule, joist hangers, post-to-beam and post-to-footing connections, and the required lateral load connection (IRC R507.9 ledger connection, R507.9.2 lateral connection, R507.2.4 flashing).
- Footing sizing derived from tributary area, the soil bearing value, and design loads per IRC Table R507.3.1, with footings shown bearing on undisturbed soil at the frost depth required by the jurisdiction (IRC R507.3).
- Details for the guards required where the walking surface is more than 30 inches above grade, and for the stairs and handrails, showing guard height and opening limits, stair riser and tread dimensions, and handrail location (IRC R312 guards, R311.7 stairs and handrails).
- For designs that fall outside the prescriptive R507 tables (for example multi-story or stacked decks, or a ledger attached to a cantilever), engineered and stamped structural plans are submitted in place of the prescriptive details (IRC R507.1 and R301).

Inspections and closing out your permit
In Franklin County, deck work is inspected in sequence as it is built: the footings before concrete is placed, the framing before the decking boards go down, and a final inspection once the deck is complete. Each stage checks the items that would be hidden or unsafe if missed.
- Footing or pier inspection in Franklin County: after the holes are dug and any forms or reinforcing are set but before concrete is placed, the inspector checks footing depth and diameter, a flat undisturbed bearing surface, and that the holes are free of water (IRC R109.1.1 foundation inspection; R507.3 footings).
- Framing inspection in Franklin County: after the deck is framed but before the decking conceals it, the inspector verifies the ledger attachment and its flashing, the fastener and bolt schedule, joist hangers and metal connectors, post-to-beam and post-to-footing connections, and the lateral load connection; call it before decking is installed (IRC R109.1.4 frame inspection; R507.9 ledger and flashing).
- Final inspection in Franklin County: after the deck is complete and before it is used, the inspector confirms guard height and opening limits (a 4 inch sphere must not pass, 4 3/8 inch at stairs), stair riser and tread dimensions, handrail height and graspability where there are 4 or more risers, stair landings, and required stair lighting (IRC R109.1.6 final inspection; R312 guards, R311.7 stairs and handrails).
Schedule each inspection in advance and pass the final before you use the work or close the permit. Request inspections through the Franklin County permit portal or by phone at 614-525-3166.

Frequently asked questions
- Do you need a deck permit in Franklin County?
- Franklin County lists 'Building Deck' outright among the activities that require a building permit, and its Residential Zoning Compliance application separately covers a patio or deck, so a deck project needs both a county building permit and a zoning approval. The Residential Code of Ohio does carve out one narrow case: a deck is exempt from building department approval only if it is no larger than 200 square feet, no more than 30 inches above grade at any point, not attached to the dwelling, and does not serve the required exit door. Even a deck that meets all four conditions still needs the zoning approval, so a permit of some kind is required either way. Always confirm with the Franklin County Building Department (Division of Building), Franklin County Economic Development and Planning Department before starting.

- How long does a deck permit take in Franklin County?
- Building permits are issued 7 to 10 days after full plan approval for properties with access to public water and sewer. Times can vary by workload and project scope, so confirm with the office.
- Where do you apply for a deck permit in Franklin County?
- You can apply through the Franklin County permit portal or contact the Franklin County Building Department (Division of Building), Franklin County Economic Development and Planning Department directly. The links are listed on this page.
- Can a homeowner pull a deck permit themselves in Franklin County?
- Under Ohio law (OAC 4101:8-1-01 Section 105.1; R.C. 3791.04(A)(1)(b); R.C. 4740.01(F)): Ohio has no statewide general contractor license, so the Residential Code of Ohio names the property owner directly as an authorized permit applicant: an owner or authorized agent who intends to construct, alter, repair, or change the occupancy of a residential building must first make application to the local certified building department and obtain approval, meaning a homeowner may pull their own permit and act as their own contractor. R.C. Chapter 4740's statewide licenses for electrical, HVAC, plumbing, refrigeration and hydronics contractors apply to 'construction projects', which R.C. 4740.01(F) defines to exclude residential buildings as defined in R.C. 3781.06, so that licensing does not reach one-, two-, or three-family home construction. In a county, township, or municipality with no residential building department certified by the state Board of Building Standards, R.C. 3791.04(A)(1)(b) and the Residential Code of Ohio's administrative rule both say the owner is not required to submit construction documents, seek approval, request inspections, or obtain a certificate of occupancy at all, which removes the state permitting framework, and with it the owner-builder question, in those jurisdictions. Confirm how Franklin County applies this before you apply.
