As housing costs continue to rise, the accessory dwelling unit (ADU) β also known as a granny flat, in-law suite, or backyard cottage β is gaining popularity as a practical housing solution. An ADU is a secondary living unit on a single-family residential lot, either attached or detached from the primary residence.
What is considered an ADU?
An ADU is a secondary living unit on a single-family residential lot that typically contains a kitchen, bathroom, and sleeping area. It can have separate entrances, utilities, and parking. The primary residence must remain the ownerβs primary residence, and the ADU cannot be sold separately.
Different types of ADUs
Attached ADUs: Attached to the primary residence, typically as an addition or conversion of an existing space such as a garage or basement.
Detached ADUs: A separate structure from the primary residence, typically located in the backyard. Our permit-ready detached ADU garage plans range from the compact 22β x 22β ADU Garage Loft (one-bedroom, 960 SF) to the spacious 28β x 28β ADU Garage Loft (two-bedroom, 1,568 SF) β each with a full two-car garage below and a complete livable apartment above.
Junior ADUs: A smaller, self-contained unit within the primary residence, typically created by converting an existing bedroom. A junior ADU typically has a kitchenette, bathroom, and separate entrance.
Benefits of building an ADU
Rental income: Homeowners can rent out their ADUs to generate extra income, helping offset the cost of construction.
Multigenerational living: ADUs provide a separate living space for family members such as elderly parents or adult children who want to live close to each other.
Increased housing supply: ADUs help increase housing supply in areas with high demand by adding units to existing residential lots.
Affordable housing: ADUs provide affordable housing options in areas where housing costs are high.
Challenges of building an ADU
Cost: Building an ADU can be expensive, especially if it requires new construction or major renovations.
Zoning regulations: Zoning regulations vary widely, and not all areas allow ADUs. Always confirm with your local planning department before committing.
Design and construction: Designing and building an ADU requires careful planning and compliance with local building codes and regulations.
Financing: ADU financing can be challenging since it may not qualify for traditional home loans.
