What drives deck prices in Mississippi
Labour
Labour is the biggest regional variable. Carpentry labour in Mississippi runs 20% below the national level, so a composite 12×16 that averages $9,216 nationally comes to about $8,200 here. On pressure-treated decks labour is more than half the bill, so the regional gap is widest on the cheapest material.
Climate
Hot, humid, with termites everywhere and hurricanes on the Gulf Coast.
Footings and frost depth
Footings in Mississippi typically go 6–12 inches deep. At 9 inches each 12 inch footing costs roughly $119 installed, and a 12×16 deck needs about 3 of them — a saving of $144 against the 24 inch depth national prices assume.
Which decking makes sense here
Our pick for most Mississippi homes: pressure-treated pine. The lowest labour cost in the country and local pine make pressure-treated exceptionally cheap here. Composite adds about $4,642 to a 12×16 deck over pressure-treated — see the full 20-year comparison in the composite vs wood calculator.
Permits and code in Mississippi
There is no statewide residential code for most of the state; cities adopt the IRC. The three coastal counties enforce wind-resistant construction.
Typical deck permit fees: $50–$250. Expect a footing inspection before concrete, a framing inspection before the decking goes down and a final. Estimate your fee with the deck permit cost calculator, and read our deck permit guide for what the drawings need to show.

Frequently asked questions
How much does it cost to build a deck in Mississippi?
A typical 12×16 ft (192 sq ft) deck in Mississippi costs about $3,558 installed in pressure-treated pine, $5,346 in cedar and $8,200 in composite. That is $17–$22 per square foot for pressure-treated and $38–$50 for composite — 10% below the US average.
Is a composite deck worth it in Mississippi?
On a 12×16 deck composite costs about $4,642 more than pressure-treated up front. The lowest labour cost in the country and local pine make pressure-treated exceptionally cheap here. Composite needs no staining, which saves a refinishing cycle every two to three years on wood.
Do I need a permit to build a deck in Mississippi?
There is no statewide residential code for most of the state; cities adopt the IRC. The three coastal counties enforce wind-resistant construction. Where a permit is required, fees typically run $50–$250. Under the model residential code, a freestanding deck under 200 sq ft and no more than 30 inches above grade that does not serve an exit door is often exempt — attaching it to the house removes that exemption.
How deep do deck footings need to be in Mississippi?
Typically 6 to 12 inches depending on the part of the state. At about 9 inches, each 12 inch footing costs roughly $119 installed, compared with $167 at a 24 inch depth. Confirm the exact depth with your building department before digging.
When is the best time to build a deck in Mississippi?
October to April. Booking a builder outside the spring rush often gets a faster start date and a keener price.
Is Mississippi expensive for deck building compared with other states?
Mississippi ranks 1 of 50 from cheapest to most expensive on our index. Carpentry labour runs 20% below the national level and materials 3% below it, which puts a typical deck 10% below the US average.
