Deck cost scales directly with size — a 200 sq ft deck costs roughly half of a 400 sq ft deck for the same material and height.
Pressure-treated wood is cheapest ($15–$25/sq ft), composite costs $25–$45/sq ft, and exotic hardwoods run $30–$60/sq ft installed.
Elevated decks need taller posts, more bracing, and stairs — each set of stairs adds $500–$2,000 depending on height and material.
Basic wood railings cost $20–$40/ft while cable, glass, or composite railings run $60–$150/ft installed.
Most jurisdictions require a building permit ($100–$500) and may require engineered plans for elevated decks, adding $300–$1,000 in design fees.
The South generally offers lower labor costs, though fast-growing metro areas are seeing rates climb. Year-round building seasons mean more consistent pricing and availability.
Budget $61–$410 for permits and inspections. Your contractor typically handles the permit process, but confirm this upfront.
