The blaze, dubbed the McKean Fire, originated off Almaden Road and Mountain Drive, in an unincorporated area just outside the San Jose city limits.
The fire burned about 10 acres as of Cal Fire's initial assessment at about 3:30 p.m. and forward progress on the blaze was halted just before 6 p.m.
Cal Fire attacked the flames with air and ground resources as the fire spread with a moderate rate of speed Sunday afternoon.
