Honest pricing from a 42-year Austin deck builder. Real ranges by material, project size, and complexity - calibrated against the 5,000+ decks, patios, pergolas, and gazebos we've built across the Austin metro since 1984.

Most Austin deck projects fall between $15,000 and $45,000. The per-square-foot range is $15-55+ installed depending on material. A basic 12x16 pressure-treated deck runs about $12,000-16,000. A 300 sq ft composite deck with railings is typically $22,000-30,000. Multi-level designs, curves, built-in seating, or pool decks push higher.
The honest answer is that every deck is different - Central Texas soil, your specific lot, the material you pick, and what features you want all change the number. We've been building decks across Austin, Georgetown, Cedar Park, Round Rock, Leander, and the rest of the Hill Country since 1984. After 5,000+ projects, we estimate accurately the first time and put the number in writing.

The same 300 sq ft deck can be a $14,000 build in pressure-treated pine or a $32,000 build in composite - or $45,000 in Ipe. Material is typically 30-45% of total project cost.
Square and rectangular decks are the most economical. Curves, octagons, and multi-level designs each add labor. Stairs to grade add roughly $1,500 - $3,000 per run. A hot tub cutout adds reinforcement labor and engineering.
Austin's expansive clay soil moves seasonally - proper footings are non-negotiable. Sloped lots, tree-protection setbacks, second-story attachments, and drainage issues all change the foundation budget. We walk the site before locking the price.
Wood railings start around $20/linear foot. Composite hits $35-60/linear foot. Cable railings preserve views at $60-100/linear foot. Built-in benches, planters, lighting, and integrated pergolas each add line items but are usually under 10% of total project cost.
Austin permits run $300 - $1,200. HOA architectural review adds $0 - $250. We bundle both into the fixed quote - no separate line item.
