What was described as an illegal electrical feed to a house in the 25300 block of 6th Street Saturday night, June 13, resulted in red tagging the house as unsuitable for occupancy.
The fire started in a wall and spread into the attic before Highland and San Manuel firefighters could bring it under control.
Highland Code Enforcement will follow up on the fire in the 1200 square foot house, and CALFIRE Captain Liz Brown says the cause is still under investigation.
