Construction was completed on the original Mobile County Government Center Annex in 1978 with the forethought that the single-story structure would one day be expanded to a four-story building.

In 2007 the Mobile County departments and their staff that occupied the Annex Building temporarily relocated and demolition began with a goal of creating a new 108,000 square foot facility. The original structure was stripped down to the concrete floor and roof slabs and concrete columns. Then once drawings and specifications were complete in September of 2008 construction began on the new multi-story Mobile County Government Center Annex.

Due to poor soil conditions the original building was constructed with a post-tension slab on piles and pile caps. In order to meet the new codes additional stair and restroom towers were designed to be added on the east and west ends of the building and a stair and elevator tower was added at the south side. These also would require piles to support the structure, however to avoid compromising the integrity of the surrounding historic buildings the architects and engineers used micro-piles and augercast piling. The design of the new building was further complicated by existence of the historic LeVert House that would remain at the north side of the new Annex with the rear wall of this 1804 structure less than 14-feet from the face of the new building's facade. The county wanted to maintain the original entrance to the Annex which was behind the LeVert House to control public access with a single secure entry point near the original elevator shaft for direct circulation from the exterior to the upper floors housing the Probate Court Judicial Departments and Courtrooms.

The desire was for the county and city governments to be located adjacent to one another to share resources as well as for public convenience. The new Annex was designed to share a security access control system and automated mechanical control system with the Government Plaza immediately to the east. The underground conduits that run between the two buildings also facilitate linking of the data and communication systems. The building's exterior is designed to compliment its historic downtown surroundings with traditional windows and precast elements punctuating the warm brick exterior skin. Focus is brought to the building's entrance with a massive precast pediment set on columns extending up the face of the building to encase the 52-foot tall glass curtainwall.

The goal for the interior spaces was to create a warm and welcoming atmosphere for both the staff and the public which was achieved with the use of rich mahogany paneling, columns and trim and warm colors on the wall and ceiling surfaces. At the first level, granite tile is used on the floors with granite wall panels at the entry and elevator lobby. The courtrooms and training spaces found on the upper floors are fitted with state-of-the-art audio/video systems with multiple user touch screen control panels. Eco-efficient gearless traction elevators, two of which are located in the original elevator shaft, connect the floors of the facility and the third was added for the secure transport of patients to the holding areas on the third floor to await their court appearance. The building was completed in March of 2010. Mobile's Probate Court and other county departments moved in right away and are currently enjoying their new home.
