What’s different about California

California's seismic codes, strict permitting, and expensive labor markets make exterior projects among the costliest in the country, especially in coastal metros.

  • Seismic bracing and stronger connectors add to structural cost.
  • Permit fees and skilled-trade labor rates here run well above the national average — usually the single biggest cost driver.

Expect quotes toward the higher end in California’s larger metros — Los Angeles, San Francisco, and San Diego — where labor and permit costs run above the state average, and lower in rural areas.

How the cost is built

Deck cost depends on size, decking material (pressure-treated pine is cheapest; composite and PVC are mid-range; tropical hardwood is premium), and structural extras like railings, stairs, and elevated footings. Permits and ledger flashing add cost on attached decks.

Resale value

A wood deck recoups about 50–83% of its cost at resale — more than a composite deck — according to the annual Remodeling Cost vs. Value report.
