Deck Cost in Columbus, Ohio

A deck is a small structure. Under the boards there are footings below the frost line, posts, beams and joists, a connection to the house or a freestanding beam beside it, and above them guards and stairs that have to meet code. The decking material gets most of the attention when a deck is planned, but in Columbus the structure — and how high it stands, how much railing it needs and how many stairs reach the yard — decides much of the price.

This guide gives typical Columbus installed ranges for 2025–2026, explains where deck money goes, and walks through the decisions that move a project from one end of a range to the other. It does not price a specific yard; that takes a site visit, a look at the house wall and the grade, and a design.

Typical Columbus installed ranges

The figures below are typical Columbus installed prices per square foot of deck surface for 2025–2026. They assume a new deck two to six feet above grade, concrete footings to frost depth, pressure-treated framing, a standard railing on the open sides, one run of stairs and a permit. They do not include removing an old deck, second-storey heights, or extras such as built-in benches, privacy screens and lighting.

National benchmarks line up with these ranges. The 2025 Cost vs Value report priced its standard project — a 16-by-20-foot deck with a built-in bench, a planter and a full railing system — at $18,263 in wood and $25,096 in composite on average, roughly $57 and $78 per square foot [1][2]. The same report estimated that the wood deck recovered about 95 percent of its cost at resale and the composite deck about 89 percent [3]. Consumer cost guides quote much lower overall averages, around $4,300 to $12,700 per project, because they include many small, low decks and price labor separately at about $15 to $35 per square foot [4].

Where deck money goes

A deck price has five main parts, and the decking boards are only one of them.

• Structure — footings, posts, beams, joists, the ledger board or freestanding beam, and the connectors and fasteners that hold it together. This part scales with height and with how far the frame has to span.
• Decking — the boards and their fastening system, from face screws in treated pine to hidden fasteners in composite.
• Guards and railing — priced by the linear foot of open edge. On a raised deck with three open sides, the railing can approach the cost of the decking.
• Stairs — stringers, treads, risers or open risers, handrails and a landing pad at the bottom.
• Permit, drawings and site work — plans, the permit, inspections, digging footings and hauling soil.

What moves the price

Size

Per-square-foot prices fall slightly as decks grow, because the permit, the drawings, mobilization and the stairs are roughly fixed costs spread over more surface. A small 10-by-12 deck can cost more per square foot than a 16-by-20 deck built from the same materials.

Height

Height changes almost everything. A low deck needs short posts and few or no guards; once any part of the walking surface is more than 30 inches above the ground measured three feet out from the edge, a 36-inch guard is required along that edge [5]. Taller decks need longer posts, bracing, larger footings and more stair. Second-storey decks off a kitchen or a walkout are the most expensive per square foot — consumer cost data put installation labor near $45 per square foot for a second-storey deck against about $15 at ground level [4].

Decking material

Moving from pressure-treated pine to capped composite typically raises the installed per-square-foot price by roughly 20 to 35 percent — the boards cost several times as much, but they are only one part of the deck — and more when the railing is upgraded to match. Deck Materials and Railings compares the options on upkeep and lifespan as well as price.

Railing

Railing runs from simple treated-wood balusters to aluminum, composite, cable railing and glass systems, and published installed prices span about $35 to $210 per linear foot [4]. A 16-by-20 deck attached along its long side has roughly 50 feet of open edge after the stair opening. At $50 a foot that is about $2,500 of railing; at $150 a foot — typical of aluminum, cable and many composite systems — it is about $7,500. Railing is often the single biggest upgrade line on a deck bid.

Stairs

Each stair run adds stringers, treads, a landing pad and, with four or more risers, a handrail on at least one side [5]. A deck six feet up needs about nine risers to reach the yard; two runs, or a run with an intermediate landing, add materially to the price.

Footings and soil

Columbus sets its frost depth at 32 inches [6], and deck footings have to bear below it so frost heave cannot lift the posts. Franklin County's deck permit guide, for example, calls for post holes 38 inches deep with the post bearing on at least six inches of concrete, sized from the footing table in the Residential Code of Ohio [7]. The number of footings follows the beam layout, and a deck with long beam spans may need fewer but larger footings. Where soil is poor, digging is impractical, or the deck sits close to a basement wall, a helical deck pile driven to load-bearing soil is a common engineered alternative at a higher price per post. Reusing old footings is rarely possible: an inspector will want to see their depth and size, and few older decks were built to today's requirements.

Removing the old deck

Demolition and disposal of an existing deck typically adds about $5 to $15 per square foot [4]. Removing an old deck also exposes the house wall behind the ledger — often the first look at that rim joist and siding in twenty years — so a replacement bid should carry an allowance for repairing rot and re-flashing the wall there.

Extras

Built-in benches, planters, privacy screens, pergola framing, low-voltage lighting and under-deck drainage systems all add cost. Lighting that needs a new circuit brings an electrical permit with it.

Columbus specifics

Permits. In the City of Columbus a deck requires plan approval and a building permit. The only exception is a deck of 200 square feet or less that is no more than 30 inches above grade at any point, is not attached to the house and does not serve the required exit door — and even then, a zoning approval is required for any deck larger than 169 square feet [5]. Suburbs set their own procedures; Permits, Footings and Code collects what is published for the area.

Inspections. Deck permits bring inspections at set points — typically the footing holes before concrete is placed, the framing before the decking covers it, and a final [7]. The schedule shapes the build, and the cost of the permit and drawings belongs in the budget.

Climate and durability. Freeze-thaw cycles and humid summers are hard on wood left wet, and the city's design criteria rate termite hazard as moderate to heavy [6]. Industry standards for treated wood now call for ground-contact treatment on framing that is critical to the structure or difficult to replace, such as joists, beams and ledger boards [8]. Connectors and fasteners in contact with treated lumber need corrosion-resistant coatings — heavy galvanizing or stainless steel [9].

Repair, resurface or replace?

An estimated 30 million of the roughly 60 million decks in the United States have exceeded their useful life [10]. When an older Columbus deck looks tired, there are three paths:

• Repair — replacing failed boards, a loose railing post or a rotted stair stringer. Cheapest, and sensible when the frame is sound and the deck is otherwise wanted as it is.
• Resurface — new decking and railing on the existing frame. This works only if the framing is sound, adequately treated, correctly attached to the house and spaced for the new boards; composite decking generally calls for joists no more than 16 inches on center, and 12 inches when boards run diagonally [11]. Many older decks fail at least one of those tests.
• Replace — a new structure from the footings up. On a deck more than 20 years old with an unflashed ledger or shallow footings, replacement is often the only option an inspector will accept.

The condition of the ledger connection usually decides the question. A ledger attached with nails, or with no flashing above it, is a structural problem rather than a cosmetic one.

Three worked examples

A 12-by-16 pressure-treated deck (192 square feet), about three feet off the ground, attached to the house, with railing on three sides and one short stair: roughly $10,000 to $15,000. Small decks sit toward the top of the per-square-foot range, because the stair, the permit and the setup are spread over less surface.

A 16-by-20 capped-composite deck (320 square feet) off a walkout about six feet up, with a standard railing and one stair run: roughly $19,200 to $28,800. Removing the old deck it replaces adds about $1,600 to $4,800, and upgrading to a cable or glass railing adds several thousand more.

A 14-by-16 second-storey composite deck (224 square feet) off a kitchen: the per-square-foot figure climbs above the composite range because of tall posts, larger footings, bracing and a long stair with a landing. Adding the second-storey labor premium of roughly $30 per square foot puts the job in the range of $20,000 to $27,000 before railing upgrades [4].

How to read a deck bid

• Footings — how many, how large, how deep, and whether concrete piers or helical piles.
• Framing — lumber size and treatment, joist spacing, beam size and post size.
• House connection — ledger fastening (lag screws or through-bolts), flashing, and lateral-load hardware, or a freestanding design.
• Hardware — connector coating suited to treated lumber.
• Decking — manufacturer, product line and color, and the fastening method.
• Railing and stairs — system, linear footage, number of stair runs and risers.
• Permit, drawings, demolition and exclusions — who draws and pulls the permit, whether removal and disposal are included, and what is excluded (electrical, landscaping, regrading).

What this means for your budget

A deck budget is mostly set by four choices made before any board is picked: the size, the height, the length of railing and the number of stairs. The decking material then moves the number by roughly 20 to 35 percent from treated pine to composite, and somewhat more for PVC. On a replacement, add demolition and an allowance for repairing the house wall behind the old ledger.

A deck bid should list those same inputs — deck size, height, decking material, railing material and length, stairs, demolition of an old deck, footings, and extras — so it can be read against the typical Columbus ranges above.
