Interior design 

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. If resale is a goal, prioritize timeless layouts and cohesive details over trend-driven finishes that date quickly. If you’re comparing approaches, weigh detached vs. garage conversion vs. basement unit based on site access, utility distance, and how much disruption you can tolerate. For a clear overview and a sensible starting checklist, see: adu custom homes. If you’re collecting bids, ask for a written scope with exclusions listed—this prevents misunderstandings later. A realistic schedule includes ordering lead times and inspection windows, not just a hopeful start date. When in doubt, simplify—fewer custom details often means faster progress and cleaner results.
