Premium south Orange County location with strong property values, pre-approved ADU program with 30-day review, and consistent demand. HOA approval is required first, but state law prevents HOAs from banning ADUs outright.
Laguna Niguel is a master-planned community in south Orange County, consistently ranked among the best places to live in California. The city is defined by its planned neighborhoods, nearly all of which are governed by homeowners associations (HOAs) — making HOA coordination the single most critical factor in any Laguna Niguel ADU project. While state law (AB 68, SB 13, AB 976) prevents HOAs from outright banning ADUs, they may impose objective design standards covering materials, colors, and architectural consistency. Laguna Niguel offers a pre-approved ADU program with an expedited 30-day review cycle, and the city's strong property values and desirable south OC location make ADU investment here a compelling long-term play.
This is the most critical step in Laguna Niguel. Submit your proposed ADU plans to your HOA's architectural review committee BEFORE approaching the city. HOAs cannot ban ADUs but may require specific materials, colors, and design elements. Get written approval before proceeding.
Contact the Community Development Department at (949) 362-4300 to learn about the city's pre-approved ADU program. Pre-approved plans receive expedited 30-day review and can simplify both HOA and city approvals.
Create architectural plans that satisfy both HOA design standards and city building codes. Include site plan, floor plan, elevations, structural engineering, MEP, and Title 24 energy calculations. Match materials and colors to your HOA's requirements.
Submit your plans along with written HOA approval to the Community Development Department. Pre-approved plans receive 30-day review. Custom plans follow the state-mandated 60-day timeline.
Once approved, pull your building permit and begin construction. Schedule required inspections at each milestone. Ensure construction complies with both city codes and HOA conditions.
Pass final inspection and receive your Certificate of Occupancy. Notify your HOA of completion. Your ADU is now legal to occupy or rent in one of south OC's most desirable communities.
