Carlsbad FAQ
Can I build a seawall to protect my Carlsbad home?
Only if your principal structure is in danger from erosion and was constructed before January 1, 1977 (Coastal Act Section 30235). You will need a Coastal Development Permit from the city with possible Coastal Commission appeal, and conditions typically include sand mitigation fees and waiver of future armoring rights.
Do I need a permit to repair my existing Carlsbad seawall?
Minor maintenance (patching, painting) typically qualifies for a CDP exemption. However, repairs that replace 50% or more of the seawall, or substantially alter its foundation, are treated as new construction and require a full Coastal Development Permit under CMC 21.204.
