Investment Insights

Based on property information with market context.

This property consists of a single existing commercial building totaling 6,750 square feet on a 4.67-acre site. The site is governed by Commercial zoning (C) intended for high-intensity retail and service development, with a framework that supports a range of professional and retail uses. The code requires business operations and storage to be conducted within a completely enclosed building. Development parameters include a maximum building height of 60 feet, a maximum lot coverage of 60 percent, and a floor area ratio (FAR) of 2:1, along with a minimum landscaping requirement of 20 percent of the site, with at least half of that landscaping located in front of or alongside buildings with street frontage.

Located in Rockwall, Texas, at 505 County Line Road, the property is positioned to accommodate a variety of investor and operator plans within the City’s Commercial (C) designation. The zoning also contemplates certain uses with conditions, and specific use permits (SUP) may allow for expanded operations such as outdoor commercial amusement, theaters, daycare facilities, or motels.

For buyers and developers, the combination of an income-producing, enclosed commercial building and a zoning platform geared toward retail, services, and professional use offers practical flexibility. Depending on the intended concept, the site can be considered for an office park, shopping center, or other mixed-use direction, subject to the applicable city requirements and any SUP processes.

Key Highlights

  • 4.67‑acre City of Rockwall commercial site with an existing 6,750‑SF building
  • Commercial (C) zoning supports executive offices, medical clinics, general retail, and personal services (e.g., hair salons, dry cleaners)
