Costs vary based on the size, type, and complexity of the project. On average, garage conversions range from $90K–$150K, while detached ADUs may run higher. We offer free quotes to give you an accurate estimate for your property.

How long does it take to build an ADU?

A typical garage conversion ADU takes 3–5 months from initial design to completion. Detached ADUs may take longer due to permitting and construction timelines.

Yes — adding an ADU typically boosts property value significantly, especially in high-demand areas like the Bay Area.
