ANSWER:
Thank you for contacting the County of Los Angeles Department of Public Works. Because the wall you have described is on a small slope, a building permit is required, even if you terrace the area with two 2-foot walls. Additionally, the use of a keystone retaining wall system is subject to the approval of our Building Division. Please visit our Building and Safety's Santa Clarita District field office at the address shown below to obtain the permit and additional information. Thank you.
