  • Keep the deck rectangular and under 200 sq ft where codes ease off.
  • Frame with pressure-treated lumber and spend only on the visible deck surface.
  • Build ground level — every foot of elevation adds framing, footings and railing.
  • Schedule in fall when builders discount to keep crews busy.
  • Skip fascia wraps and picture framing details that add labor with no structural value.
