Setbacks & Height Limits in Irving

This guide explains the basic setback and height rules that apply to residential construction in Irving, Texas. These numbers depend on your exact zoning district, overlay zones, and lot geometry, so always confirm with the City of Irving Planning Department at (972) 721-2600 before finalizing plans.

What Are Setbacks?

A setback is the minimum required distance between a building and a lot line. Setbacks are measured from the property line to the nearest point of the building (typically the wall, though eaves, chimneys, and bay windows have their own rules).

Irving's zoning ordinance specifies front, side, and rear setbacks separately for each zoning district. Corner lots have two "front" setbacks — one per street frontage — plus one interior side and one rear setback.

Typical Residential Setbacks by District

For Irving's most common single-family residential zones:

The SF-40 district is Irving's lowest-density residential zone for estate-style development on 40,000 sq ft lots; because of its size, its exact setback dimensions should be confirmed directly from the district schedule in the zoning ordinance. Higher-density MF (Multi-Family Residential) and commercial zones have separate setback schedules.

Height Limits

Maximum building height in Irving's single-family residential zones (SF-40, SF-10, SF-7.5) is 35 feet, measured from average grade to the highest point of the roof. Height rules can get more complicated in:

• Multi-family (MF) districts — height varies and is tied to density and buffer requirements adjacent to single-family zones
• Commercial and mixed-use districts — generally allow greater height, often tied to floor area or setbacks
• Airport and flight-path overlays — proximity to DFW International Airport can cap height under FAA Part 77 surfaces
• Floodplain areas — lowest floor elevation requirements effectively raise usable height in some lots

Lot Coverage and FAR

Beyond setbacks and height, two other numbers shape how much you can build:

• Lot coverage — the percentage of the lot covered by buildings (main structure plus accessory structures). Irving's single-family districts set district-specific coverage maximums in the zoning ordinance.
• Floor Area Ratio (FAR) — the ratio of total building floor area to lot area. Irving primarily uses FAR in non-residential and mixed-use districts rather than in single-family zones.

Common Exceptions and Encroachments

Most zoning codes — Irving included — allow certain features to project into required setbacks. Typical allowances include:

• Eaves and gutters (usually up to 2 ft)
• Chimneys (up to 2 ft)
• Uncovered porches, stoops, and steps
• Air conditioning condensers (subject to side-yard clearance rules)
• Bay windows (limited projection)

Fences, retaining walls, and accessory structures (sheds, detached garages, pool equipment) typically have separate rules — check the accessory structures section of Irving's zoning ordinance.

State ADU Overrides

If your project is an Accessory Dwelling Unit (ADU), note that Texas has no statewide ADU mandate overriding local zoning — Irving's local rules fully apply. See the Irving zoning overview for this city's current ADU guidance.

How to Look Up Your Specific Requirements

1. Find your zoning district — contact the Irving Planning Department or check the city GIS for your parcel's zone
2. Read the district regulations — look up your zone in the Irving Code of Ordinances on Municode for setbacks, height, and coverage
3. Check for overlays — airport, floodplain, and corridor overlays can modify the base rules
4. Call planning staff — Irving Planning at (972) 721-2600 offers pre-application guidance before you commit to design

Variances

If your project cannot meet the strict letter of the zoning code, you may apply for a variance through the City of Irving Board of Adjustment — a formal request to deviate from the rules based on hardship specific to your lot. Variances are discretionary and typically require public hearings. See the Variance Application Guide for the general process.
