Grand Prairie Accessory Structure, Deck, Patio, and Porch Permit Guide

Grand Prairie requires approved permits for all residential accessory structures and all residential decks, patios, and porches regardless of size.

Permit takeaway

Grand Prairie says all residential accessory structures, including sheds, garages, shops, and gazebos, require approved permits, and all residential decks, patios, and porches require approved permits regardless of size.

Zoning and placement

Submittals must show property lines, easements, roadways, existing and proposed structures, setbacks, and whether the lot is a corner lot.

Building and trade review

Accessory structures over 200 square feet require foundation design sealed by a Texas-registered engineer, and inspections may include foundation, framing, and final approval.
