Yes, most decks require a permit. However, freestanding decks under 200 sq. ft. and less than 30 inches above grade are generally exempt. As of January 2026, Indianapolis updated its fee schedule, with some structural fees for new builds increasing significantly to around $850.
A new wood deck in Indianapolis currently yields a high return on investment of approximately 102.7%, while composite decks offer a slightly lower but still strong ROI of 97.9%.
In 2026, composite decking (like Trex) costs between $25 and $45 per sq. ft. installed, whereas pressure-treated wood ranges from $15 to $25 per sq. ft. Despite the higher upfront cost, composite saves homeowners $3,000–$5,000 in maintenance over 20 years.
A standard 16x20 deck typically takes 1–2 weeks for physical construction. However, permit processing times in Marion County can add several weeks, though 2026 fee increases were implemented specifically to fund faster turnaround times.
