ADU Design FAQ: Family & Multi-Family Accessory Dwelling Units
Accessory Dwelling Unit (ADU) Design FAQ
At Dorman Associates, we design ADUs that combine style, functionality, and long-term value. Whether you're adding a Family ADU for relatives or a Multi-Family ADU for income potential, we make the process seamless from concept to completion.
What is an ADU?
An ADU (Accessory Dwelling Unit) is a self-contained living space on the same property as your primary home. It can be attached, detached, or created through a conversion—like transforming a garage into a fully equipped living unit.
What types of ADUs do you design?
We specialize in:
- Family ADUs – Perfect for multi-generational living, guest accommodations, or providing a private space for adult children.
- Multi-Family ADUs – Designed for developers, landlords, and investors looking to add rentable units to existing multi-family properties.
How long does the ADU design process take?
For most projects, the design process takes 3–6 months, depending on complexity, site conditions, and local permitting timelines. Our goal is to create a streamlined, proactive workflow so you can move to construction without costly delays.
Can you help with permitting?
Yes. We navigate local zoning requirements, building codes, and state ADU laws on your behalf. This ensures your project meets all regulations and avoids unnecessary approval delays.
How much does it cost to build an ADU?
Costs vary based on size, materials, and site conditions. In California, typical ADU construction ranges from $250 to $500 per square foot. We provide detailed cost estimates early in the process so you can plan confidently.
Do ADUs increase property value?
Absolutely. A well-designed ADU can significantly boost your property value and generate rental income. It’s one of the most versatile investments in residential real estate today.
