Irving's Accessory Structures: The Rules That Matter

Every city handles accessory structures a little differently. In Irving, Texas, there are 4 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.

Garage Conversions

Irving will not issue a permit to convert an attached garage into living space unless the project meets every condition in UDC § 4.4.10: matching exterior materials, no wood siding on the new wall, a 16-to-25-foot paved driveway, house-only entry, and no separate dwelling unit. The rule covers conversions permitted after October 22, 2009.

Key details: Governing section: UDC § 4.4.10. Driveway width: 16 to 25 feet, fully paved. Entry requirement: Only from inside the house. Separate unit: Not allowed under this section. Wood siding: Barred on the conversion wall.

Section 4.4.10 is enforced at the permit counter: the building official simply will not approve a garage-conversion permit that skips a required condition, so noncompliant plans are rejected before work starts. Converting a garage without pulling a permit at all exposes the owner to the city's standard building-code enforcement, including a stop-work order and a requirement to restore the space to a garage, or bring it into full code compliance, before any certificate of occupancy will issue.

Shed & Carport Rules

A backyard shed in Irving falls under UDC § 3.1.4, which caps a detached accessory building on a lot under half an acre at 10% of the lot area or 2,500 square feet, whichever is smaller, and sets a 5-foot minimum setback and a 10-foot height limit.

Key details: Max size, lots under ½ acre: 10% of lot or 2,500 sq. ft.. Lots ½ acre or larger: No maximum square footage. Minimum side/rear setback: 5 feet (up to 10 ft. tall). Base height limit: 10 feet to roof peak. Height with extra setback: Up to 20 ft. with 15-ft. setback.

Building or expanding a shed beyond the 10%/2,500-square-foot cap, inside the 5-foot setback, or above the 10-foot height limit (without the earned setback trade-off up to 20 feet) is a zoning violation the city's building official can enforce with a stop-work order or by withholding final inspection approval. A metal-exterior shed 150 square feet or larger, a shed wired with its own separate utility meter, or one used as a dwelling or for business also violates §§ 3.1.5 through 3.1.7 and can be cited for correction or removal; letting the three-month building permit lapse without requesting the one allowed extension voids permitted status for the ongoing work.

ADU Rental Restrictions

Irving's Unified Development Code defines a 'servants quarters,' the only accessory dwelling unit its zoning code recognizes, as living quarters restricted to people employed on the property. Section 9.3 flatly bars renting it out or using it as a separate home for anyone else, and requires it to share utility meters with the main house rather than carry its own.

Key details: ADU category recognized: "servants quarters" only. Rental of ADU: prohibited outright. Utility meters: must share main house, none separate. Approval path: S-P-1 site plan rezoning. Occupancy limited to: on-premises employees only.

Renting a servants quarters or using it as an independent residence violates both the UDC's use definition and, where the quarters was approved via S-P-1 rezoning, the terms of that zoning grant. Enforcement runs through § 1.8.1: a Class C misdemeanor with fines up to $2,000 for knowing zoning violations, each day of continued rental a separate offense, plus potential injunctive action by the city attorney.

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

ADU Rules

Irving will not let a homeowner add a guest apartment or accessory dwelling by right. Under Unified Development Code § 2.4.7(b)(2), guest and servant's quarters are a lawful accessory use in a single-family district only after the property is rezoned into an S-P-1 detailed site plan district by City Council under § 2.7.3, following Planning and Zoning Commission review and a public hearing.

Key details: Approval required: S-P-1 site plan rezoning. Rezoning authority: Irving City Council. Recommending body: Planning and Zoning Commission. Front setback (varies): 50 to 80 feet by district. Street right-of-way setback: 20 feet minimum.

Building or occupying a guest or servant's quarters without the required S-P-1 rezoning is a UDC violation under § 1.8.1: a Class C misdemeanor, fined up to $2,000 when the violation is knowing or intentional and involves zoning, with each day of noncompliance a separate offense. The city attorney may also pursue injunctive relief in court to force removal or bring the structure into compliance.

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

The Bottom Line

Irving is tougher than many cities when it comes to accessory structures. Out of the 4 rules covered here, 2 are rated strict. If you are a homeowner, renter, or business owner in Irving, take the time to understand these requirements before they become a problem. Most violations come with fines, and some repeat violations can escalate.
