The Milpitas station complex is located near the intersection of East Capitol Avenue and the Montague Expressway, near the south border of Milpitas.
The BART tracks run roughly north-south in a trench below street level, with two 700-foot (210 m)-long side platforms.
The station building is approximately 430 by 160 feet (131 m × 49 m), with an undulating roofline and three large circular skylights.
Entrances are on the east and west sides of the station building, near its southern end, leading to a central corridor.
Fare control areas are on opposite sides of the corridor; both have stairs and escalators to the platform, with elevators in the north fare control area.

The BART station features stained glass windows by BJ Katz and Chris Klein, titled Ethos of Imagination, above the main entrance.
Twenty support columns along the platforms are encased in ceramic tiles by Amy Trachtenberg, titled Ecstatic Voyaging, patterned after the ikat dyeing technique.

The light rail tracks are elevated above East Capitol Avenue, running approximately northwest-southeast.
A mezzanine is located under the single island platform, with stairs and an elevator to the median of East Capitol Avenue at South Milpitas Boulevard.
A pedestrian bridge leads from the west side of the BART building (with escalators and an elevator) southwest to the light rail mezzanine.

The bus plaza is located west of the BART station building.
It is served by nine VTA bus routes (20, 44, 47, 60, 66, 70, 71, 77, and 104) and one AC Transit route (217); it serves as a transfer point between the two bus systems.
It is the only BART station served by both VTA and AC Transit buses, and the only VTA light rail station served by AC Transit buses.
The six-story, 1,631 space paid parking garage is located east of the BART building.
A paid 185-space indoor bike parking structure is located underneath the footbridge; free bike racks are dispersed around the station.
