CC&R's conflict with city setback rules-which takes precedence?

[Ed B.]

I just ran into an interesting situation. I just got  remodeling plans approved by the city, and they gave me a permit, but I was just notified that my plans are in violation of the CC&R's.

CC&R's have a setback requirement of 25 ft.

However, the city's building regulations only require  a setback of 20 ft.

Which set of rules takes priority?  The CC&R's (enacted some 50 years ago), or the city's rules?

Thanks for any info. from anyone who has experience with this!
