The Oceanside Fire Department (OFD) is responded to reports of a fire at a duplex in Oceanside just before 11:30 Saturday morning.
The fire sparked at a single-story property at 4435 Via La Jolla off Avenida Del Gado near Old Grove Road and Mission Avenue, south of State Route 76.
OFD investigators confirmed that the fire was caused by an electrical short outside on the back patio of the home and spread inside and to the attached property.
No humans or animals were injured in the fire but seven adults were displaced, according to the OFD. The Red Cross stepped in and provided temporary housing for the displaced residents.
OFD says that crews were able to extinguish the fire within 30 minutes.
