Street closures will be in effect for the OC Marathon on Sunday, May 4, in Santa Ana, Newport Beach, and Costa Mesa. See the closures.

I want to start a business in Santa Ana. What do I do?

One of the first steps is to contact the Planning Division (714) 647-5804 to see whether you are permitted to do what you want to do. A new sign? A parking lot sale? Both of these activities requires a permit.
