The Building Inspections & Permits division sits inside the Development Services Department (which also includes Planning & Zoning, GIS, and Code Compliance). All building permit applications, plan submittals, inspection requests, and contractor registrations are processed through the iWorQ online portal (in production since January 2, 2023). All contractors must register with the City of Justin before performing work within city limits. Adopted codes (verified on the live building dept page): 2018 International Building Code, 2018 International Residential Code, 2018 International Energy Code, 2018 International Plumbing Code, and 2017 National Electrical Code (Justin is on the 2018 I-codes, not the 2021 cycle some neighboring DFW cities use). Staff contacts published on the page: Sasha Torres (Building Official) and Patricia Hollis (Permit Technician); direct email addresses are routed through CivicPlus contact forms rather than public mailto links, so no direct email is listed. Fee schedule is published as the Treeline Fees How-to Guide PDF served from the city's DocumentCenter. Counter hours are not posted on the building dept page or the homepage; main city phone line 940-648-2541. ZIP 76247 also covers neighboring portions of Roanoke and unincorporated Denton County; for parcels inside Justin city limits, this department is the AHJ. Practical notes for homeowners: vicinity to DFW International Airport and Alliance/Fort Worth Meacham airspace means FAA Part 77 notice may be triggered for tall accessory structures (towers, large flagpoles, antennas) depending on parcel location; the area is in TDLR / Texas-administered seismic and wind territory with ASCE 7 wind design for North Texas (DFW tornado-alley periphery) and expansive (shrink-swell) North Texas clay soils that drive foundation and pier design for residential additions, pools, and retaining walls. TxDOT FM-156 / SH-114 corridor parcels may require a TxDOT driveway/right-of-way permit in addition to the city permit.
