Irving FAQ
How do I get an ADU permit in Irving?
Confirm the lot's zoning district under UDC Chapter 2, then check UDC Section 3.1 for accessory structure rules. R-6 and R-7.5 single-family districts do not permit ADUs by right — you'll need rezoning or a Board of Adjustment Special Exception. Once zoning is approved, apply for a building permit through Irving Development Services.
Does Irving allow ADUs by right?
Not in the typical R-6 and R-7.5 single-family districts. UDC Section 3.1 generally limits detached accessory buildings to those without second kitchens. ADUs with kitchens usually require rezoning to a district that permits two-family use or a Special Exception from the Board of Adjustment.
