Irving charges standard building permit, plan review, and trade permit fees on ADUs through Development Services. Water and wastewater impact fees apply under authority of Texas Local Government Code Chapter 395 when a new utility connection is established. Texas has no statewide ADU impact fee waiver. Sharing the principal dwelling's water and sewer tap is the most common cost-reduction strategy.
Irving does not offer ADU-specific impact fee waivers. Standard fees apply: residential building permit fees based on construction valuation, plan review fees, and separate trade permits for electrical, plumbing, and mechanical work, all administered by Irving Development Services. Water and wastewater impact fees are authorized under Texas Local Government Code Chapter 395 (Financing Capital Improvements Required by New Development) and administered through the city's utility billing department; new water and sewer taps trigger the full impact fee for a single-family equivalent, while ADUs sharing the principal dwelling's tap typically avoid most of the impact-fee charge. Roadway impact fees, where applicable under Chapter 395, may add a per-dwelling-unit charge depending on the service area. Texas has no state-mandated ADU exemption analogous to California's Government Code Section 65852.2(f). Electric service in Irving is provided by Oncor, natural gas by Atmos Energy, and water/sewer by the City of Irving — each utility charges its own service-extension fees separately from the impact fee. ORD-2023-10699 adopted the 2021 IFC and updated building code references, but did not change the impact fee schedule. Texas HB 14 (2023) prohibits a regulatory authority from collecting an additional fee for third-party review of development documents.
Failure to pay impact fees results in permit denial, utility connection denial, or revocation. Building or occupying an ADU on an unauthorized utility connection is a building code and utility theft violation. Texas Local Government Code Section 54.001 authorizes civil penalties up to $500 per day for zoning violations and $2,000 per day for building/fire violations.
