The body was found at 2 p.m. Tuesday at a home on Carolina Street.
Lt. Gary Faulkner said the person, an adult, had been dead for quite some time. The person's age, race and gender have not been determined.
Faulkner said the death is not connected to the murders of Segundia Allen, 63, and Marcaria Smart, 60, who were found dead in a home on Upland Court in Vallejo late Tuesday afternoon.
