Is under $15,000 realistic for a 12×10 build in 2026?▾
It depends on three things: (1) your state's labor multiplier — CA/NY/MA add 20-35% to national averages; (2) whether you DIY or hire pros — DIY saves 35-50% labor; (3) season — March-April and October-November shoulder seasons drop pricing 8-15% vs peak May-September. The numbers shown reflect national 2026-Q1 averages.
What's the cheapest 12×10 deck that's still code-compliant?▾
PT pine decking + PT framing + wood baluster railing + standard 16″ O.C. joists + footings below frost line + IRC R312-compliant 36″ guard. For 12×10 that's ~$4,232-$7,220 installed, or 50-65% less if you DIY. Code compliance is non-negotiable — under-spec'd framing fails inspection and gets torn down at owner expense.
