What to bring into the first discussion.
The first stage defines the household goal, property type, ADU option, site constraints, records, and unresolved investigations. Skipping that work often moves uncertainty into drawings and estimates.
Look closely at the existing conditions.
Design and permit preparation develop the documents. The team should track drawing versions, consultant responsibilities, City comments, product decisions, and scope updates together.
Connect the decision to the full scope.
Preconstruction confirms the agreement, permitted documents, selections, long-lead items, site logistics, protections, and the initial inspection sequence. A calendar is useful only when its assumptions are visible.
Use current sources and responsible professionals.
Construction moves through site preparation, foundations or existing-condition work, structure, enclosure, rough systems, insulation, finishes, fixtures, exterior work, inspections, and corrections. The order depends on the project.
Read the related Costa Mesa ADU services, cost guide, and permit guide for the construction context.
Choose a practical next step.
Handoff includes agreed restoration, applicable signoffs, equipment information, warranties, operation instructions, and remaining-item tracking. Permit issuance, construction completion, and authorization to occupy are separate milestones.
