Why Homeowners Are Adding ADUs

California's updated ADU permitting guidelines have made it significantly easier and faster for homeowners to add living space to their existing properties. Rather than going through the disruption and expense of moving, many property owners are now turning to accessory dwelling unit builders like ADU Design + Build to expand their homes in place.

There are several practical reasons homeowners pursue ADU construction:

1. Additional living space — An ADU provides a separate, self-contained area that can serve as a granny flat, in-law suite, or guest accommodation without the need to relocate.
2. Increased property value — Adding an ADU to an existing property can meaningfully increase its equity. A roughly 1:1 return on investment is not uncommon for well-executed ADU projects.
3. Rental income potential — ADUs in Los Angeles County average over $2,000 per month in rental income, whether used for long-term tenants or short-term rentals. This makes them a practical income-generating option for many homeowners.
