The substation is located north of the existing Southwest Regional Court Center in Avondale and complements the established aesthetic while providing a recognizable identity for the Sheriff’s Office. This shared facility on 7.8 acres combines a 25,312-square foot MCSO Sheriff’s Office and a 2,864-square-foot Fleet Maintenance, Equipment Services component, a 1,982-square foot covered Fuel Station, and a 2,087-square-foot Drive-through Car Wash. Site improvements include a public plaza, public parking, secure staff parking, an emergency back-up generator, a drive-thru sally port, secure fitness patio, and secure staff courtyard.

This facility houses command, investigation, patrol, evidence, a shared fitness room and detention personnel. A 1,550-square foot central courtyard connects the indoors to the outdoors while also providing natural lighting and a secure outdoor space for occupants. This shared facility maximizes operational cost savings and security opportunities while respecting the operational requirements of each department. Exterior building materials are specified with durability, insulation, sound absorption, and ease of serviceability. The interior finishes are also neutral and common spaces such as fitness, corridors and courtyard display shot-blasted CMU throughout. Attention to durable and easily maintained interior and exterior materials ensures the facility will maintain its civic presence, sense of security, strength, and quality image for years to come.
