FAQ
What exactly is an ADU, and how can it benefit my property in Fremont, CA?
An ADU—short for Accessory Dwelling Unit—is a secondary living space on your property. It could be a detached backyard cottage, garage conversion, or a basement apartment. ADUs are great for adding rental income, giving family members independent living space, or simply expanding your home without moving.

What does Dream Build Services handle during an ADU project?
Everything—from the first design sketch to the finishing touches. Our team takes care of permits, construction, plumbing, electrical, HVAC, cabinetry, and interior finishes, so you don’t have to juggle multiple contractors.
Do I need special permits or zoning approval for an ADU in the Bay Area?
Yes. We handle all the required permits, zoning reviews, and compliance checks with your local building department. You’ll have a fully approved, legal ADU when we’re done.
How long does it take to build an ADU?
Smaller conversions may take a few months, while larger detached ADUs with full kitchens and bathrooms can take a bit longer. Once we review your site, we’ll give you a clear, realistic timeline.
Will the new ADU match the look of my main home?
Absolutely. We design every unit to blend seamlessly with your home’s architecture, colors, and materials—so it looks like it’s always been there.
Can an ADU increase my home’s value or rental potential?
Definitely. An ADU adds livable space and can increase your property value and monthly income potential. Many homeowners in Fremont and the East Bay are seeing excellent returns from ADU investments.
