Deck Cost per Square Foot in Alachua
Per-square-foot pricing is the quickest way to put a rough number on a new deck. Around Alachua, a pressure-treated pine deck generally runs about $25 to $40 per square foot installed, and a composite deck about $40 to $60. That rate is for the whole platform: the concrete, the treated frame, the walking surface, guards where the code calls for them, and a single plain stair.
The spread inside each range comes from the details. A low, rectangular deck with a short run of railing sits near the bottom. A deck eight feet in the air with a long railing, a wide stair and a picture-frame border sits near the top. Composite carries a higher range because the boards, hidden fasteners and matching railings cost more, even though the framing underneath is the same treated lumber either way.
| Project | Typical range | What moves the price |
|---|---|---|
| Pressure-treated wood deck | $4,500–$12,000 | Size, height, railing length, stair count |
| Composite or PVC deck | $8,000–$22,000 | Board line, hidden fasteners, border boards, railing style |
| Pool or multi-level deck | $12,000 to $25,000+ | Number of levels, stainless hardware, slip-resistant boards |
| Stairs and railings | $40–$120 per linear ft of rail | Wood, composite, aluminum or cable; landings; stair width |
Deck Cost by Size in Alachua
The rows below apply those rates to four footprints, from a landing to a deck that spans the back of the house. They are multiplication, not quotes. Small decks tend to land at or above the top of their range, because the permit, the stairs and the trip to set footings cost nearly the same whether the deck is 120 square feet or 300.
| Deck size | Pressure-treated wood | Composite |
|---|---|---|
| 10 × 12 ft (120 sq ft), back-door landing | $3,000–$4,800 | $4,800–$7,200 |
| 14 × 18 ft (252 sq ft), table and grill | $6,300–$10,100 | $10,100–$15,100 |
| 20 × 20 ft (400 sq ft), dining plus lounge | $10,000–$16,000 | $16,000–$24,000 |
| 20 × 28 ft (560 sq ft), full-width entertaining deck | $14,000–$22,400 | $22,400–$33,600 |
What Changes the Price of a Deck in Alachua
Footprint alone won’t predict the bill. When two similar-looking decks get very different prices, the reason is almost always somewhere on this list:
- Height off the ground. A raised deck needs taller posts, bigger footings, bracing, more railing and longer stairs. Height is the single biggest driver after size.
- Stairs and landings. Every stair run adds stringers, treads, railings and often a landing pad at the bottom.
- Railing material. Wood rail is the least expensive. Composite, powder-coated aluminum and cable rail each step up from there.
- Shape and pattern. Angles, curves, picture-frame borders and diagonal boards add cutting time and, for diagonals, closer joist spacing.
- Site access. A fenced backyard with a narrow gate, a steep slope or a septic field in the way slows every delivery and footing.
- Old deck removal. Tearing out and hauling away an existing deck is often $1,000 to $3,000.
- Electrical. Lights, outlets and ceiling fans are priced and permitted as their own scope.

Screened Porch, Pergola and Covered Deck Costs
Adding a roof changes the math. A roof needs beams and posts sized for its weight and for wind uplift, a connection to the house or its own footings, and engineering for the screen walls. That is why outdoor rooms sit in their own bracket.
| Outdoor room or add-on | Typical range | Notes |
|---|---|---|
| Screened porch or screen room | $8,000–$25,000+ | Roof type, size, and whether a new floor is needed |
| Screening an existing covered deck | $12–$25 per sq ft | Only if posts and beams can take the screen load |
| Pergola | $4,000–$15,000 | Open cedar rafters cost least; motorized louvers cost most |
| Covered deck or patio cover | Quoted on site | Shingle or metal roofing, gutters and fan wiring add up |
If you think you might want a roof later, say so at the estimate. Sizing the footings and beams for a future roof now costs far less than reinforcing a finished deck. The screened porch vs. open deck article walks through that decision.
Deck Repair, Replacement and Upkeep Costs
Not every project starts from bare ground. For an existing deck, the price depends on what is failing.
- Deck repair: a few hundred dollars for boards, a railing section or stair treads, up to several thousand when joists, beams, posts or the ledger need work.
- Deck replacement: priced like a new deck, plus removal and haul-away.
- Framing inspection: free with any estimate, with written notes if you ask for them.
- Cleaning and sealing: roughly $1.50 to $4 per square foot for wood decks, depending on condition and product.
A rough rule: if the trouble is on the surface, repair it. If a large share of the framing is soft, compare the repair price against a new deck before spending money on the old one.
Deck Permit Offices Around Alachua
Attached decks, raised decks and anything with a roof generally need a building permit and inspections. Which office issues it depends on where the house sits, not on the mailing address:
- Inside Alachua city limits: the City of Alachua Planning & Community Development Department, Building Division.
- Unincorporated Alachua County: Alachua County Growth Management, Building Division. County fees start from a base amount by permit type, plus an amount tied to construction value.
- Other Alachua County cities: places such as High Springs and Newberry run their own building departments. Smaller towns may differ, so we confirm the office for each address.
- Columbia County: the City of Lake City inside its limits, Columbia County outside them, including much of the Fort White area.
- Union, Levy and Marion counties: Lake Butler and Worthington Springs fall in Union County, Williston in Levy County, and Ocala, McIntosh and Reddick in Marion County, each with city or county offices depending on the address.
We don’t publish fee amounts because they depend on the project and change over time. Your estimate lists the permit as its own line. HOA approval is separate, and many Alachua subdivisions require it before a deck, pergola or screen room goes up. More detail is in the city vs. county permit guide.
Ways to Keep an Alachua Deck on Budget
- Skip the angles. Square corners mean standard lumber lengths, fewer cuts and less waste in the dumpster.
- Mind the height. If the floor can sit a step or two lower, posts, railings and stairs all shrink.
- Mix materials. Composite decking with a wood or aluminum railing, or composite on the main level and wood on a low lower level, can split the difference.
- Plan in phases. Build the deck now with footings sized for a roof, then add the screen room when the budget allows.
- Book in the dry season. Fall and winter fill up first, so getting on the schedule early helps. The timing guide covers each season.
