How long does an ADU project take from permits to move-in?
ADU: Timelines vary by city and scope. Design & permits commonly take several weeks to a few months; construction typically ranges from a few months for conversions to longer for ground-up detached builds. Contractors within our network will map milestones for your specific jurisdiction in Greater Los Angeles.
How much does an ADU cost and what drives the budget?
ADU: Costs depend on size, site conditions, foundation, utilities, finishes, and whether it’s a conversion or a new detached unit. After a quick feasibility review, contractors within our network provide a clear scope and line-item budget so you know where every dollar goes.
Is my property eligible for an ADU?
ADU: Most single-family lots and many multifamily properties can add ADUs, subject to zoning, setbacks, height, and utility capacity. Contractors within our network confirm eligibility and outline any site-specific constraints during your free consultation.
What permits and inspections are required?
ADU: Contractors and design professionals within our network prepare architectural plans and coordinate structural/MEP engineering as needed. They submit to your local jurisdiction, address plan check comments, and schedule inspections through final approval.
What services do you provide from start to finish?
ADU: Feasibility & budgeting, architectural design, structural & MEP coordination, permit submittals, construction coordination, utilities, Title 24/energy compliance, and inspection support—until you receive final sign-off.
