Within the first year a chapel, granary, tack room, and three other rooms had been constructed, using native labor. In 1788 two more rooms were added. In 1789 a second granary was built, quarters for the mayordomo, and quarters for the missionaries were built. Also, a covered passageway which temporarily served as a kitchen. Crops of wheat and beans were planted in quantities to provide for the needs of the parent mission. At its peak the asistencia consisted of a three-wing main structure surrounding a central plaza. Corn, peas, barley, asparagus, and rosemary would, in time also be cultivated, along with grape vineyards and groves of peach and quince trees. Due to a significant decline in the native population, the facility was used mainly as an outpost to graze cattle after 1790.
A plaque in Sanchez Adobe Park depicts the former Asistencia's floor plan.
