ZC26-06 — Accessory Dwelling (Story Guest House) in Colleyville, TX

This case involves a request for a Special Use Permit to allow an accessory dwelling unit (guest house) on a 4.2-acre residential lot zoned R-40 Single-Family Residential. The HOA of the adjacent Castleton Manor gated community opposes the project, citing concerns about the proposed structure exceeding size limitations under city code, lack of clarity on height and setback compliance, potential negative impacts on neighborhood property values, and environmental impacts to established trees. The approval of this permit could establish precedent for accessory dwelling development in the area and affect property rights and neighborhood character in established residential communities.
