Detached ADUs
Detached ADUs are standalone structures built separately from the main house, typically located in the backyard, and offer the highest level of privacy and flexibility for homeowners. These units are ideal for generating rental income, providing comfortable guest accommodations, or creating independent living spaces for family members such as aging parents or adult children. With their own entrances, kitchens, and bathrooms, detached ADUs function as fully self-contained homes. Our team guides you through every step—from custom design and site planning to permitting and construction—ensuring your detached ADU not only meets all Gilroy zoning and building requirements but also complements your property’s style and adds lasting value.
Attached ADUs
Attached ADUs are built as extensions of your existing home, sharing at least one wall with the main structure. This makes them a smart choice for homeowners who want to expand their living space without sacrificing valuable yard or outdoor areas. These units can be seamlessly blended into your home’s current floor plan and architectural style, creating a natural flow between the original house and the new addition. Attached ADUs are perfect for adding extra bedrooms, a spacious home office, or a comfortable suite for extended family—offering both privacy and easy access to the main residence. From initial design and navigating Gilroy’s permitting process to final construction, our team handles every detail, ensuring your attached ADU complies with all local regulations and elevates both the functionality and value of your property.
