What this budget gets you — 10×8

Decking material
PT pine
PT pine · $25-$40/sqft installed × 80 sqft = $2,000-$3,200
Railing system
Wood baluster
$28-$55/lf × 38 lf = $1,064-$2,090
Framing
Standard PT
2×10 joists at 16″ O.C., doubled 2×10 beam, 4×4 posts at frost-line footings. Material ~$640-$960 included in totals above.
Stairs
3-6 step flight
A 1-flight stair to grade typically adds $400-1,200 in materials + labor. Built-in to the totals above.
Permit
$150-$450
Permit fee varies by jurisdiction. Required for any deck attached to a house, regardless of size. Pull permits before starting work — retroactive fines run 2-4× normal fees.
Labor + profit
~50% of cost
Pro install labor + contractor profit is typically 45-55% of total installed cost. DIY saves this layer entirely — but expect 3-8 weekends of work for a typical residential deck.
