A house in a row of terraced properties suffered damage after fire spread from an outdoor area into the building.
Fire crews attended the mid-terrace residence on Kidborough Road in Crawley during the afternoon.
Authorities advised people to avoid the area and told local householders to keep windows and doors shut.
A spokesperson for West Sussex Fire and Rescue Service confirmed that the emergency was reported at 3.14pm on Friday 24 April concerning a fire at a property on Kidborough Road in Crawley.
