Approval Timeline
Typical residential trade permits may be issued same day to a few business days when complete. Residential remodels, additions, accessory structures, and new homes commonly take about 1 to 3 weeks for first review. Commercial finish-outs and tenant improvements often take 2 to 4 weeks for first review, while new commercial buildings, shell buildings, civil/site-related projects, restaurants, medical uses, and projects requiring fire or floodplain review can take 4 to 8+ weeks depending on completeness and resubmittals.
Common Requirements
Common submittals include a completed permit application, project valuation, site address, owner and contractor information, contractor registration, scope of work, construction drawings, site plan or survey, floor plans, framing and foundation details, MEP layouts when applicable, energy compliance documentation, product approvals, and structural calculations for engineered work. Commercial projects typically require code analysis, occupancy classification, construction type, occupant load, life-safety plan, accessibility/TAS compliance information, fire protection drawings when applicable, and sometimes civil plans, drainage studies, utility plans, and a traffic or parking analysis.
Zoning Information
Irving uses zoning districts and development standards to regulate land use, setbacks, height, lot coverage, parking, landscaping, signs, accessory structures, and special-use requirements. Before a building permit is issued, the city checks whether the proposed work is allowed in the zoning district and whether it meets the applicable site standards. Projects in planned development districts, overlay areas, redevelopment corridors, or properties needing a specific use permit may require zoning approval before building permit review can be completed.
Permit Costs
Irving permit fees are generally based on the type of permit and/or project valuation. Minor residential trade permits may be roughly $50 to $200+, while fences, roofs, pools, remodels, and additions can range from about $100 to several hundred dollars. New homes and commercial projects are commonly several hundred to several thousand dollars depending on valuation, plan review fees, inspections, utility-related fees, fire review, certificate of occupancy fees, and reinspection fees. Applicants should confirm current fees with the City of Irving fee schedule before budgeting.
Engineering Requirements
A Texas-licensed professional engineer or architect is typically required for commercial buildings, structural alterations, non-prescriptive designs, retaining walls, unusual foundations, steel or engineered wood framing, large openings in load-bearing walls, storm shelters, complex MEP systems, and projects outside the prescriptive IRC provisions. Engineered foundation designs are common for North Texas soils. Commercial projects usually require sealed drawings, and fire protection or MEP designs may require discipline-specific seals depending on scope.
