The Colleyville Planning and Zoning Commission on a November 2025 agenda approved a special-use permit allowing a detached accessory building that brings combined accessory structures on the property at 4905 Belden Trail to 2,143 square feet, or roughly 7.4% of the lot area, above the 4% allowance in the subdivision’s planned unit development regulations.

Planning staff told the commission the lot’s 4% accessory-building allowance equals 1,162 square feet and that, while the accessory total exceeds that threshold, the proposed structure meets all other zoning standards, including lot coverage and impervious-surface limits. "Staff recommends approval on this case," the planning staff said during the presentation.

Rodney Owens, representing homeowner Brian Steffek, said the detached structure is intended primarily as a home gym and multipurpose training area for baseball — Steffek is active as a coach and has two sons who play. Owens explained that attaching the space to the house would trigger a larger rear-yard setback (25 feet) that would make the desired internal dimensions impractical. "One of the primary uses of it would be for training for baseball," Owens said. Owens also told commissioners the homeowners engaged the HOA and the subdivision’s architectural review committee and that the adjacent neighbor had submitted a letter of support.

Commissioners questioned the numeric calculations and the code basis for allowing an accessory total beyond 4 percent. Staff walked through the code interpretation: the PUD allows accessory buildings up to 4% by right and provides a special-use permit process to authorize larger accessory structures when other criteria — such as compatibility, lot coverage and setbacks — are met. Staff noted renderings and elevations were provided and suggested a condition that the final structure conform to the presented materials to improve compatibility with neighboring homes.

With that background, Commissioner Savoy moved to approve Case ZC25-029; Commissioner Arnold seconded. The motion carried by a vote of 5 to 1, with Commissioner Remley recorded as the sole dissenting vote. The decision authorizes the special-use permit; staff noted two letters of support were on file and that no members of the public spoke during the hearing.

The approval permits the homeowners to construct the detached accessory building as proposed. There was no motion recorded to refer the matter elsewhere; the commission closed the public hearing and proceeded with the vote.
