ADU Construction in the San Francisco Bay Area
More space. More options. More value. That’s what a custom ADU can bring to your home—and Handyman Heroes is your go-to crew for building it right.
Whether it’s for family and guests or for generating rental income, accessory dwelling units (ADUs) are one of the smartest upgrades a Bay Area homeowner can make. And we’re proud to build them across San Francisco, Oakland, Berkeley, Marin County, Palo Alto, and nearby cities.
What’s an ADU?
An ADU (Accessory Dwelling Unit) is a fully independent living space built on your existing property. It might be:
- A detached backyard cottage.
- An attached apartment over the garage.
- A converted basement or lower level.
- A stand-alone unit with its own entrance.
It’s flexible, functional, and future-proof. Whether you’re expanding for multi-generational living, building out space for an in-law, or creating rental income—an ADU just makes sense.
Why Homeowners Love ADUs
ADUs are skyrocketing in popularity across the Bay Area—and for good reason:
- Create rental income from unused space.
- House aging parents or adult children with privacy.
- Increase your property’s value.
- Add square footage without moving.
- Build a flexible guest space or home office.
- Take advantage of recent zoning updates in California.
We’ll walk you through every step—from planning to permits to final build.
