Dana Point Homes with ADU, Casita & Guest House

Welcome to the Dana Point, CA guide for Accessory Dwelling Units (ADUs), casitas, and guest houses. This page is designed for coastal homeowners and investors who need verified information on ADU size limits, Coastal Zone rules, parking and setbacks, and live MLS listings for ADU-capable properties.

Dana Point is a harbor city on the southern Orange County coast with one of the few marinas in the region, direct access to Pacific Coast Highway and I-5, and a mix of bluff-top, ocean-view, and inland neighborhoods. That combination makes properly permitted ADUs attractive for multigenerational living, extended-stay coastal rentals, and long-term equity growth.

Fun Fact: Dana Point is recognized as the “Dolphin & Whale Watching Capital of the World” and was named a certified Whale Heritage Site, which helps drive steady tourism and visitor demand near the harbor.

Why Are ADUs in Dana Point a Strong Coastal Investment?

• ADUs in Dana Point can be built up to 1,200 sq ft under state ADU law when local standards are met. California’s ADU statute allows detached units up to 1,200 square feet, and Dana Point’s ordinance is reviewed for compliance with that framework, with height, lot coverage, and design standards refined locally.
• Coastal Zone parcels may trigger Coastal Development Permit (CDP) review for ADUs. In Dana Point’s Coastal Overlay Zone, some ADUs are processed as “second dwelling units” under the Local Coastal Program, which can require a CDP and additional coastal findings.
• California’s AB 976 permanently removes owner-occupancy requirements for ADUs in Dana Point. As of January 1, 2024, cities cannot require owners to live in either the main home or the ADU, which greatly expands long-term rental and investment flexibility.
• Coastal tourism and harbor access support durable ADU rental demand. Proximity to the harbor, beaches, and whale-watching attractions creates ongoing demand for high-quality second units suited to extended-stay guests and long-term tenants.

Which Dana Point Properties Work Best for ADUs and Casitas?

Not every coastal parcel is equal when it comes to ADU placement, access, and review timelines:

• Inland and non-bluff neighborhoods often offer simpler ADU permitting. Properties outside the most sensitive coastal bluff and harbor areas may avoid extra coastal findings and can move forward more directly under the ADU ordinance, while still following standard design and setback rules.
• Lots with usable rear yards are prime candidates for detached ADUs. When a Dana Point lot has adequate backyard depth, owners can often fit a detached ADU using state-allowed reduced rear and side setbacks, subject to local height and coverage limits.
• Existing garages may be converted to ADUs under state conversion rules. State ADU law allows many attached and detached garages to be converted to ADUs, and replacement parking is not required in several cases, especially near transit or when within an existing structure.
• Multifamily properties can sometimes support multiple conversion ADUs. Under California’s ADU framework, qualifying multifamily parcels can add interior conversion ADUs plus limited detached ADUs, provided life-safety and building code standards are met.
