Common questions

How much does a 16×24 Composite Deck cost in California?

About $22,763 fully built by a local crew in 2026, or roughly $7,705 for the materials kit alone. Most fair bids land between $20,942 and $25,039.

Do I need a permit?

Most counties require a building permit for structures over 200 sq ft. Call your county building department with your size and location before you order materials.
