Is under $5,000 realistic for a 24×20 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.

What's the cheapest 24×20 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 24×20 that's ~$14,128-$23,380 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.
