About ADU's by Design
ADU's by Design is a company based in the Inland Empire area of Southern California, specializing in the design and construction of Accessory Dwelling Units (ADUs). They offer a full-service approach, handling everything from initial design through project completion. Their service area covers Riverside and San Bernardino County.

Services Offered
ADU's by Design provides a range of construction and design services, including:
- Detached ADU construction — standalone units built in the backyard or elsewhere on the property
- Attached ADUs — units connected to the main residence
- Garage conversions — converting existing garage space into a livable unit
- Home building — new residential construction
- Architectural design — design services tailored to the client's needs and lot
- Remodeling — improvements to existing structures
- Consultation — guidance for homeowners exploring ADU options
They also offer pre-designed unit options, which allows them to provide more predictable pricing that aligns with a range of budgets. This approach is part of what they describe as their one-stop-shop model — managing the process from design through completion so clients don't have to coordinate between multiple contractors or vendors.
Past projects include a custom two-story house with a detached ADU in Corona, CA, a second-story two-bedroom ADU with a private entrance in Riverside, CA, and a planned urban development involving 17 detached two-story homes across five floor plans in Riverside, CA. These examples reflect the range of project types and scales they have taken on.
What Is an ADU and Why Build One?
An accessory dwelling unit is a self-contained living space added to a single-family property. It typically includes its own entrance, kitchen, bathroom, and living area. ADUs are sometimes referred to as granny flats, backyard cottages, in-law suites, or casitas. They can be detached structures, attached additions, or conversions of existing spaces such as garages.
There are several practical reasons homeowners choose to build an ADU:
- Additional rental income — an ADU can be rented out to help offset mortgage payments or property taxes
- Multigenerational living — providing a separate but nearby space for family members
- Increased property value — adding livable square footage and income potential can raise a property's market value
- Flexible use — the space can serve as a home office, studio, or guesthouse depending on the owner's needs
- Energy efficiency — new ADU construction can incorporate modern materials and technology to reduce utility costs
- Affordable housing contribution — ADUs add housing options in established neighborhoods
ADU's by Design also hosts informational seminars for homeowners interested in learning more about the ADU building process, the opportunities involved, and what to expect from start to finish. These sessions are held periodically and are open to those considering an ADU project.
For homeowners and investors in Riverside and San Bernardino County looking for an experienced ADU builder, ADU's by Design offers a structured process, a multi-licensed team, and a range of services designed to take a project from concept to completion.
