Flames swept through an apartment complex early Tuesday morning on Valley Hi Drive.
Investigators say five units were destroyed by the fire, and several others were damaged.
Police arrested 26-year-old Longinos Togonon for a number of charges, including assault with a deadly weapon, violating a restraining order and arson.
Neighbors reportedly tackled Togonon and held him until he could be taken into custody.
No one was reported to have been hurt in the fire.
