Dana Point is a coastal city in south Orange County known for its harbor, world-class surfing, and year-round tourism economy. The Dana Point Harbor revitalization project is driving renewed real estate interest throughout the city. Most properties in Dana Point fall within the California Coastal Zone, requiring careful navigation of coastal permitting requirements. The city has had ongoing exchanges with the California Department of Housing and Community Development (HCD) regarding ADU ordinance compliance, and Ordinance No. 25-04 now governs current ADU rules. Dana Point's marinas, beaches, and mild year-round weather create consistent rental demand from both long-term tenants and tourism-adjacent workers.
