What is an ADU?
An Accessory Dwelling Unit is a secondary residential living space located on the same property as a primary home. It can be attached, detached, or created through the conversion of an existing structure.
Can an ADU be used as a rental property?
In many cases, yes. Local regulations vary, so it's important to review zoning and permitting requirements before beginning construction.
Are ADUs a good investment?
Many homeowners choose ADU Construction because it can provide additional living space, rental opportunities, and increased property value.
Can an ADU be designed for aging family members?
Absolutely. Many ADUs incorporate Accessible Home Remodeling features and Aging in Place Remodeling strategies to create safe, comfortable, and independent living environments.
How long does ADU construction typically take?
Project timelines vary based on design complexity, permitting requirements, site conditions, and the size of the structure. We provide a detailed timeline during the planning process.
