Irving staff advance UDC amendments to implement state housing law; commission debates 6- vs. 8-story minimum

City planning staff on Aug. 4 asked the Irving Planning and Zoning Commission to recommend a package of Unified Development Code amendments intended to implement state Senate Bill 8 40, which takes effect Sept. 1 and preempts many local zoning controls for multifamily and mixed‑use residential development. Staff said building-code updates approved July 31 would be effective Aug. 30 and that the commission’s recommendation will go to City Council on Aug. 28.

The proposals cover definitions, administrative process changes and development standards. Staff said the draft carries the state definitions for “mixed‑use residential” and “multifamily residential” into local code, preserves limited protections for heavy‑industrial uses, and shifts some review criteria into the administrative building‑permit process so projects that meet objective standards can proceed without discretionary zoning hearings.

Planning staff described several new technical standards: a minimum of 20% of gross site area as open space, a requirement that half of on‑site parking be covered and no compact spaces, balcony and patio size minimums, bicycle storage and secure room requirements, mandatory laundry hookups, and a menu of required amenities (pool, dog park, trail, playground) to ensure usable open space. Staff said ground‑floor commercial space in mixed‑use buildings should be “commercial ready” and that the city will require mailed notices and on‑site signage at the time of building-permit issuance so neighbors are informed even when a project proceeds administratively.

The most contested element was a staff‑recommended minimum building height for eligible multifamily/mixed‑use projects. Staff said the City Council directed a baseline of six occupied stories to encourage more durable construction materials and long‑term building quality. Several commissioners and one council member urged a higher minimum of eight stories, saying it would more reliably require concrete or steel construction and reduce the chance of heavy‑timber structures that, they argued, offer lower longevity and fire‑resilience. Others on the commission cautioned that a hard minimum could force higher construction costs that developers may not be able to support in some neighborhoods.

Planning staff stressed limits imposed by state law: certain local development standards (unit size, parking for conversions, and some density controls) are preempted when SB 8 40 applies. As one planning official put it during the session, “The state gave us a very blunt instrument,” and staff said the changes were drafted to preserve as much local quality control as the law allows. Staff recommended the commission send its recommendation on the draft UDC amendments to City Council at their August 28 meeting.

The commission did not vote to adopt specific text at the work session; commissioners agreed to make formal recommendations at the work session and during the scheduled August 18 followup, with the item expected to go to council on Aug. 28.
