Brown was involved in altercation last October outside a hotel in Washington, D.C., where the singer faces misdemeanor assault charges after a man accused Brown of striking him.
Brown, arrested after being dismissed from a court-ordered rehab sentence, has been in custody since mid-March.
Superior Court Judge James R. Brandlin sentenced Brown to a year in county jail, but gave credit for good behavior and time served, including rehab. The singer faces an additional 131 days behind bars.
Brandlin also ordered that Brown will complete the remainder of his 1,000 hours of community labor once he is released and will remain on probation until Jan 31 of next year, assuming he can stay out of trouble until then.
