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.
Long cooling seasons and heavy summer rain drive the two problems we see most here: moisture getting into assemblies, and anything that traps it staying wet.
Garage conversions read as the cheap route and often are, but the slab usually sits below the required floor height and lacks a moisture barrier, so the real scope includes the floor system most quotes leave out.
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
