The fastest way to derail an ADU is to start with finishes before you’ve solved the fundamentals. Before sketches get serious, map constraints: access for crews, utility tie-ins, drainage, and how the unit will sit for sunlight and privacy. These factors often drive cost more than square footage. A quick way to avoid budget shock is to define allowances early (fixtures, cabinetry, finishes) and tie payments to clear milestones. On the build side, prioritize moisture control, insulation, ventilation, and sound separation. Those details determine whether the space feels quiet and comfortable year-round.

If you’re collecting bids, ask for a written scope with exclusions listed—this prevents misunderstandings later. Good plans reduce rework; rework is where budgets quietly leak.
