Why Bayfront
ADUs are all we do, so we do them well.
An accessory dwelling unit is one of the highest-return improvements you can make to a Bay Area property, added living space for family, a home office, or rental income, without buying more land. But permits, setbacks, utilities, and engineering trip up most owners.
We specialize in exactly this. From the first site walk to your final inspection, one team carries the project, with a fixed price and a fixed schedule, so there are no surprises halfway through.
What an ADU can add
- Rental income that offsets your mortgage
- Space for aging parents or adult kids, close but private
- A dedicated home office or studio
- Long-term property value, permitted and on record
Ask Keyli or book a free site walk, we'll model the numbers for your specific lot.

In their words
Owners who now have more home.
“They handled the permits, the engineering, everything. We went from an empty backyard to a rented two-bedroom in one season with no surprises.”
“The garage conversion paid for itself faster than we expected. Clean work, clear schedule, and they actually picked up the phone.”
“Sam and Brad walked our lot, told us exactly what was possible, and then delivered it. It felt like working with engineers, not a sales pitch.”
