ADU House Plans

An ADU, formally known as an Accessory Dwelling Unit, is perfect to add living space or create rental income! These unique plans are small, independent dwellings that are built on the same lot as a primary home.

An ADU house plan can serve as a primary residence, added living space for family and guests, or a rental unit, if your town allows. ADU homes have been on the rise as a solution to affordable housing shortages and as multi-generational living becomes more popular to accommodate aging family members. Sometimes referred to as granny flats or in-law apartments, accessory dwellings can be attached or detached from a single-family home, but they usually have a separate entrance. An attached ADU can be in a bonus space, finished basement or attic, or tucked behind or to the side of the main home's interior. Detached ADUs are usually located on the grounds of your property or above the garage. ADUs can offer the convenience and comfort of independent living quarters if your primary home doesn’t have the space. ADUs are also a great option for those wanting to downsize and rent out their primary residence to generate more income. Be sure to check with your building and zoning departments and your HOA, if you have one, before planning for an ADU. Since every jurisdiction has different rules, you’ll want to know what your local codes mandate. If you need assistance or have questions, contact us by email, live chat, or calling 866-214-2242 and let us help you find the perfect ADU home plan.

Frequently Asked Questions


What is an accessory dwelling unit?

An accessory dwelling unit, or ADU for short, is a secondary residence located on the same property as a main residence. ADUs can be attached to the main house, but they are often separate structures. Many designs have studio-style accommodations or a small bedroom or two, so ask yourself what you need and how much lot space you have to work with to make it happen!


What are the advantages of having an ADU?

An ADU adds tons of value to your property. You can use the extra space as an office, studio, or secondary living area away from the main house, but the primary function of an ADU is to add more housing to a property. This is perfect for keeping adult children or aging in-laws close, or renting out to generate income to offset the mortgage.


Are there any rules about adding an ADU to my home?

Many jurisdictions are in favor of ADUs to help provide more housing, but others are opposed due to potential strain on local systems from the increased population. So, whether you're allowed to build an ADU will primarily depend on your local codes. If you proceed, make sure you're ready to build your ADU to meet local codes and pass inspections, like you would any other residence.
