An ADU is a zoning project before it is a construction project. Setbacks, lot coverage, parking relief, owner-occupancy rules and utility capacity decide what can legally go on your lot, and they vary street by street.
Utilities are the line item that surprises people: whether your existing panel and sewer lateral can carry a second dwelling, or whether you are trenching to the main.
Freeze-thaw cycling is the governing condition. Water that gets into masonry, grout or a roof detail expands when it freezes and widens the gap it entered through.
What the job includes
- Zoning and feasibility review
- Plan sets and permit submittal
- Detached, attached and garage conversions
- Separate utility metering
- Kitchen and bath rough-in
- Final inspection and occupancy sign-off
