Deck vs Patio Cost

A patio is cheaper — about 40–60% less than a deck. Expect $5–$17/sq ft for a patio (poured concrete to pavers) versus $25–$80/sq ft for a deck (pressure-treated to composite). On a 320 sq ft footprint that's roughly $1,600–$7,000 for a patio vs $6,800–$18,000 for a deck. But a deck returns more at resale (~83% for wood vs ~50% for a patio) and works on slopes a patio can't. The rule of thumb: sloped or elevated lot → deck; flat, well-drained lot → patio.

Which fits your yard?

Modern house with a raised wood deck

Sloped or uneven lot → build a deck

A deck spans a grade change on posts and footings — no excavation, no retaining walls, and you get an elevated view. Once the surface is more than ~30" above grade a guardrail is required (IRC R312), which is priced into every deck estimate here.

Concrete patio in a flat backyard with potted plants

Flat, well-drained lot → pour a patio

On level ground a patio is far cheaper and near-zero maintenance. It needs a compacted gravel base and good drainage — on a slope you'd pay for fill and retaining that erases the savings, and freeze-thaw can crack a poorly-based slab.

Guardrail included (deck 36″ off grade)

IRC R312

IRC R312 mandates a 36″ guardrail on open edges when deck height exceeds 30″. 40 lf priced at Mid composite tier.

Building permit included in budget

IRC R105

Northeast typical permit fee is in the budget. Most jurisdictions require a permit for decks > 200 sqft, > 30″ above grade, or attached to the house.

Hidden-fastener install premium baked in

Manufacturer specs

Mid composite uses hidden-fastener clip systems (Cortex / CamoClip / Trex Universal) — labor takes 25–30% longer than face-screwing PT. Already inside the tier's installed $/sqft band.

The honest verdict

Pick a patio if your yard is flat, your budget is tight, and you never want to think about maintenance again. A poured slab at $5–$15/sq ft is the cheapest usable outdoor floor you can build, and it will outlast a wood deck with zero re-staining.

Pick a deck if your lot slopes, you want an elevated view, or resale ROI matters — a deck recoups far more of its cost and is often the only structure that even works on a grade. Yes, it costs 2–3× a patio up front, but the value it adds and the sites it fits are things a patio can't match.

Deck vs patio cost questions, answered.

  • A patio is cheaper — usually 40–60% less than a comparable deck. Poured concrete runs about $5–$15/sq ft and pavers $10–$17/sq ft, while a deck runs $25–$50/sq ft in pressure-treated wood and $40–$80/sq ft in composite. On a 320 sq ft footprint that's roughly $1,600–$7,000 for a patio versus $6,800–$18,000 for a deck. A deck costs more because it's a framed, elevated structure — footings below the frost line, joists, beams, railings, and stairs — where a patio is hardscape laid on grade.

  • A deck. A wood deck recoups roughly 65–83% of its cost at resale and composite ~68% (Remodeling's Cost vs. Value report; the figure varies by year and region), while a patio typically returns closer to 50%. A deck also adds more absolute dollars because it costs more to build. If resale ROI is the goal, a deck wins; if the goal is the lowest upfront cost, a patio wins.

  • Let the ground decide: slope → deck, flat → patio. A deck spans a sloped or uneven lot on posts and gives you an elevated view without major excavation, and it's the only option once the surface sits more than ~30 inches above grade (where a guardrail is code). A patio needs flat, well-drained ground — on a slope you'd pay for excavation, fill, and retaining walls that erase the savings, and freeze-thaw can crack a slab.

  • Almost always for a deck, rarely for an on-grade patio. Decks are structural and usually attach to the house, so most jurisdictions require a permit (a freestanding deck under 200 sq ft and under 30 inches high is a common exception). A ground-level patio typically needs no permit unless you add a roof, an outdoor kitchen, or electrical. Always confirm with your local building department.

  • A patio needs far less upkeep. Concrete and pavers are near-zero maintenance and last decades; a wood deck needs cleaning and re-staining every 2–3 years and lasts 15–30 years, while composite decking is wash-only and lasts 25–50 years. Over a 10-year window a wood deck's recurring stain/seal cost is a real line item a patio doesn't have — worth factoring into the true cost of ownership.
