Architects and designers increasingly design homes that come with an Attached Accessory Dwelling Unit (ADU). An ADU, also known as a secondary dwelling unit, is a small apartment or living space built detached or attached to an existing home. Home owners can use an ADU to create a rental income or as additional living space for a family member or a guest. ADU designs have been popularized by the tiny house movement, which encourages people to downsize their living areas to conserve resources. Today, many architects are designing contemporary and traditional house designs with attached ADUs. These attached ADUs, also known as granny flats, provide small, comfortable living spaces for an extra family member or an extra source of income. From small homes to two-family house plans, here are the top 10 Art Deco house designs with attached ADU.House Designs with Attached ADUs

The Benefits of Building a House Plan with an Attached Accessory Dwelling Unit
Building a house plan with an attached Accessory Dwelling Unit (ADU) can provide a number of significant benefits to homeowners. An ADU is an additional unit of housing that is built on the same property as an existing primary dwelling. Typically, it is a smaller dwelling than the primary residence, and it may be attached to the primary structure, or detached. One popular, growing trend is to attach the ADU to an existing house plan.
More Living Space
When you build an ADU, you can create additional living space on your property. Whether it is used for extended family visits, a rental property, or another purpose, an attached ADU can give you extra space for visitors and even extra income from a rental property. Alternatively, the homeowner may choose to use the additional space for additional bedroom space, an office, or even a recreational area.
Increased Property Value
Attaching an ADU to an existing house plan can add significant value to your existing structure, potentially increasing the resale value of your home. Depending on local regulations, this additional structure could even make the home more appealing to potential buyers who may be seeking a rental unit to serve as an additional income source.
Simplify Construction and Permitting
Attaching an ADU to an existing house plan can make the process of designing and permitting much simpler than building a stand-alone structure. It can save time, labor and materials costs, and may even reduce the number of permits required. Additionally, all electrical, plumbing and HVAC infrastructure will likely be provided via the existing house plan, reducing the cost of the new construction.
Create Flexible Living Arrangements
An attached ADU can offer a homeowner flexibility when it comes to living arrangements. If the ADU is built with a kitchen, bathroom, bedroom and living area, it can provide an independent living space. Alternatively, the ADU can offer a connection to the main structure, with the space being used as an in-law apartment or for additional family members. It also gives the homeowner the flexibility to decide how the ADU will be used in the future.
Improved Energy Efficiency
By attaching an ADU to an existing house plan, homeowners can take advantage of improved energy efficiency. Building a structure on the same property as an existing primary residence allows for more efficient use of infrastructure including HVAC and electrical systems. This can provide significant advantages in terms of reduced energy costs.
Building a house plan with an attached ADU can offer a number of key advantages, including additional living space, improved property value and energy efficiency, and flexible living arrangements. It can also simplify the process of designing and permitting the attachment, creating a win-win situation for homeowners.
