Camarillo FAQ
Do I need a permit for a retaining wall in Camarillo?
Yes, if the wall exceeds 4 feet from the bottom of the footing to the top. Walls over 4 feet also need engineered plans from a licensed engineer. Walls under 4 feet are generally permit-exempt but must comply with zoning setback requirements.
Can I put a fence on top of my retaining wall?
Yes, but the combined height is measured from the lower finished grade. A 4-foot retaining wall with a 6-foot fence creates a 10-foot total height, which may exceed zoning limits. Check with Community Development at (805) 388-5360 for your specific situation.
Who maintains retaining walls in Camarillo HOA communities?
It depends on the CC&Rs. Retaining walls that are part of the original tract development may be HOA common area responsibility. Walls built by individual owners on their lots are typically the owner's responsibility. Review your CC&Rs or contact your HOA.
Port Hueneme FAQ
