No stickers are needed.
For residential streets parking is on the side with numbers corresponding to the year. Park on the even numbered side of the street on even years and vice versa. Beginning on Jan 1 2019 park on the odd side of the street.
Be sure to park in the direction with the flow of traffic too.
