If a court finds that an action of a city, county, or city and county is in violation of Section 65913.1 or 65913.2, the city, county, or city and county shall bring its action into compliance within 60 days. However, the court shall retain jurisdiction to enforce its decision. Upon the court's determination that the 60-day period for compliance would place an undue hardship on the city, county, or city and county, the court may extend the time period for compliance by an additional 60 days.
