To find a list of cities in Los Angeles County that have more registered Republicans than registered Democrats, I just had to look it up on the CA Sec. of State's website. The most recent figures of registered voters, and which parties they registered with, was published February 10, 2017. I found these cities in the county have more registered R than D.
Just north of the L.A. city limits, Santa Clarita -- 45,134 Republicans to 42,275 Democrats.
Just north of Glendale/Pasadena, La Canada Flintridge -- 6,131 Republicans to 4,823 Democrats.
Just south of Pasadena, San Marino -- 3,158 Republicans to 2,080 Democrats.
Four little cities adjacent to one another in the area called
the Palos Verdes Peninsula:Palos Verdes Estates -- 4,819 Republicans to 2,664 Democrats
Rancho Palos Verdes -- 11,147 Republicans to 9,336 Democrats
