Here’s a detailed pricing breakdown:

| Tropical Hardwood (Ipe) | $35/sq.ft. | $50/sq.ft. | $70/sq.ft. | Luxury appearance, extreme durability |

Pressure-treated wood is the most affordable ($15–$30/sq.ft.) but requires annual maintenance.
Composite decking costs more upfront ($30–$55/sq.ft.) but lasts 25+ years with minimal upkeep.
Exotic hardwoods (Ipe, Tigerwood) offer unmatched beauty ($35–$70/sq.ft.) but need specialized installation.
Pro Tip: Composite materials perform exceptionally well in Austin’s heat and humidity, resisting warping and fading better than wood.
Simple rectangular decks are the most cost-effective.
Multi-level designs, curved edges, or cantilevered sections add 20–40% to labor costs.
Wraparound decks or those with multiple access points require more footings and framing.
Ground-level decks (< 30″ tall) are simplest and cheapest.
Elevated decks (common for 2nd-floor access) need:
Additional structural beams ($5–$15/sq.ft. extra)
Staircases ($1,000–$4,000 per set)
Railings for safety (required for decks > 30″ tall)
Austin-Specific Note: Many areas have expansive clay soil, which may require deeper footings or helical piers to prevent shifting (+$1,500–$5,000).
Deck builders typically charge $30–$80/hour, with labor comprising 40–60% of total project costs.
| Task | Average Cost |
|---|---|
| Design & Planning | $500–$2,000 |
| Demolition (if needed) | $1,000–$3,000 |
| Framing | $4–$10/sq.ft. |
| Decking Installation | $5–$12/sq.ft. |
| Railings | $30–$100/LF |
Austin requires permits for:
Decks > 30″ above grade
Decks attached to the house
Electrical work (for lighting)
Permit fees: $150–$800 depending on scope.
Engineering stamps may be needed for complex designs (+$500–$1,500).
Skip This at Your Peril: Unpermitted decks can cause issues during home sales and may need costly retrofitting.
| Feature | Added Cost |
|---|---|
| Premium railings (glass, cable) | $50–$150/LF |
| Built-in seating/planters | $800–$3,000 |
| Under-deck drainage system | $2,000–$5,000 |
