Irving's Accessory Structures: The Rules That Matter

Every city handles accessory structures a little differently. In Irving, Texas, there are 9 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Non-compliant tiny homes may face code violations, required removal, or modifications to meet code.

ADU Rules

Irving's UDC permits ADUs in certain residential zones. Texas SB 1412 (2023) expanded ADU rights statewide. Local zoning districts determine where ADUs are allowed.

Key details: Permitted: In certain residential zones. State Law: TX SB 1412 (2023) expands rights. Building Permit: Required. Standards: Must meet lot coverage, setbacks, size limits. Check Eligibility: Planning Dept. (972) 721-2424.

Building without a permit: stop-work orders and fines. Non-conforming ADUs must be brought into compliance or removed.

Carport Rules

Irving carports are limited to 400 sq ft, max 10-foot height, and can only shelter up to 2 vehicles. Lots over 1/2 acre may have two carports. No storage allowed in carports.

Key details: Max Size: 400 sq ft. Max Height: 10 feet. Vehicles: Maximum 2. Storage: Not permitted in carports. Large Lots: Up to two carports (> 1/2 acre).

Building without a permit: fines. Using carport for storage: code violation.

Shed Rules

Irving limits detached accessory buildings to 10% of lot area or 2,500 sq ft max on lots under 1/2 acre. No size limit on lots 1/2 acre or larger. Building permits required.

Key details: Max Size (< 1/2 acre): 10% of lot or 2,500 sq ft. Max Size (>= 1/2 acre): No maximum. Permit: Required. Easements: Cannot build on easements. Processing: ~3 business days.

Building without a permit: fines, required removal, or retroactive permit with additional fees.

ADU Permits

Irving regulates accessory dwelling units under the Unified Development Code (UDC), with accessory buildings and structures on residential lots controlled by UDC Section 3.1. Single-family residential districts include R-6, R-7.5, and other R-series classifications with minimum lot sizes corresponding to their numbers. Detached ADUs typically require either rezoning or a Special Exception from the Board of Adjustment, plus a building permit through Development Services.

Key details: Governing Code: Irving UDC (Land Development Code). Accessory Section: UDC Section 3.1. Single-Family Minimums: R-6 (6,000 sf), R-7.5 (7,500 sf). Process: Rezoning or BOA Special Exception. Adopted Building Code: 2021 IRC, 2020 NEC (ORD-2023-10699).

Building or occupying an ADU without zoning approval and a building permit is a Class C misdemeanor under Texas Local Government Code Section 54.001 and Irving Code, with fines up to $2,000 per day for building code violations and $500 per day for zoning violations. Irving Development Services and Code Enforcement may issue stop-work orders, deny utility connections, and place liens for abatement. Unpermitted ADUs typically block resale and refinancing.

Compared to other cities, Irving takes a harder line on adu permits. The enforcement and penalty structure reflects that.

ADU Owner Occupancy

Irving commonly imposes owner-occupancy as a condition of any Board of Adjustment Special Exception or rezoning granted for an ADU. The owner must occupy either the principal dwelling or the ADU as their permanent residence, typically backed by a recorded affidavit or deed restriction with the Dallas County Clerk (or Tarrant County for west Irving lots). Texas state law has not preempted local owner-occupancy rules.

Key details: When Required: BOA Special Exception conditions. Recording County: Dallas (or Tarrant for west Irving). Evidence Accepted: TX license, voter reg, homestead. LLC Ownership: Member residency affidavit. Both Units Rented: Prohibited (R-6/R-7.5 districts).

Operating an ADU without satisfying the owner-occupancy condition is a code violation. Irving Code Enforcement may issue a notice of violation, refer the matter to municipal court, and recommend revocation of the Special Exception to the Board of Adjustment. Fines up to $500 per day apply under Texas Local Government Code Section 54.001 for zoning violations.

This is one of the stricter rules in Irving's municipal code. If you are unsure whether your situation complies, it is worth checking with the city before proceeding.

ADU Impact Fees

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.

Key details: Permit Fee Basis: Construction valuation. Water/Sewer Impact: TX LGC Ch. 395 schedule. Tap Sharing: Avoids most impact fees. Roadway Impact: May apply by service area. State Waiver: None — Texas has no ADU exemption.

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.

ADU Rental Restrictions

Irving ADUs may be rented long-term (30+ days) provided owner occupancy continues under the Special Exception condition. Short-term rentals under 30 days fall under Texas Tax Code Chapter 156 hotel occupancy tax (6% state) and Irving's local hotel occupancy tax under Tex. Tax Code Chapter 351 (commonly 7%). Irving regulates STR use through the UDC; STR operation in single-family districts can be challenged.

Key details: Long-Term (30+ days): Permitted with owner occupancy. State Hotel Tax: 6% under TX Tax Code Ch. 156. Local Hotel Tax: ~7% under TX Tax Code Ch. 351. Single-Family Districts: STR use often challenged. Tax Remittance: TX Comptroller + Irving Finance.

Operating an STR without remitting state and local hotel occupancy tax exposes the owner to back taxes, penalties, and interest under Texas Tax Code Chapters 156 and 351. Zoning violations carry fines up to $500 per day under Texas Local Government Code Section 54.001. Irving Code Enforcement may issue stop-use orders. STR listings near DFW Airport receive heightened scrutiny.

Compared to other cities, Irving takes a harder line on adu rental restrictions. The enforcement and penalty structure reflects that.

If you are a homeowner, renter, or business owner in Irving, take the time to understand these requirements before they become a problem.
