Are you having a hard time finding the right home in your budget? Or maybe you already own a home but could use some extra income or a designated space for aging loved ones. Either way, accessory dwelling units (ADUs) could be the smart solution you’ve been looking for in today’s market.

What Is an ADU?

According to Fannie Mae, an ADU is a small, separate living space that’s on the same lot as a single-family home. It must include its own areas for living, sleeping, cooking, and bathrooms independent of the main house. And they can take shape in a few different ways. Fannie Mae adds, an ADU can be:

  • Within a main home, such as a basement apartment
  • Attached to a main home, such as a living area over a garage
  • Detached from the home entirely; it could even be a manufactured home

The Benefits of ADUs

ADUs are growing in popularity as more people discover why they’re so practical. In fact, a recent survey shows that 24% of agents say an ADU, such as a mother-in-law house, is one of the most desired features buyers are looking for right now.

The growing appeal makes sense. With rising costs all around you, an ADU can help supplement your income and ease some of the strain on your wallet. Whether you buy a home that has one already or you add one on, it gives you the option to rent out that portion of your home to help pay your mortgage.

Here are some of the other top benefits of ADUs, according to Freddie Mac and the AARP:

  • Living Close, But Still Separate: You get the best of both worlds — more quality time together, plus privacy when you want it. If that sounds like a win, it might be worth looking for a home with an ADU or adding one to your home.
  • Aging in Place: Similarly, ADUs allow older people to be close to loved ones who can help them if they need it as they age. It’s a sweet spot that offers independence and support from loved ones. For example, if your parents are getting older and you want them nearby, this could be a great option for you.
  • Built-In Childcare: If your family’s living in the ADU, you may be able to use them for childcare, which can also be a big cost savings. Plus, it gives your kids more time with their grandparents.

It’s worth noting that since an ADU exists on a single-family lot as a secondary dwelling, it typically can’t be sold separately from the primary residence. And while that’s changing in some states, regulations vary by location. So, connect with a local real estate expert for the most up-to-date guidance.

Bottom Line

In today’s market, buying a home with an ADU or adding one to your current house could be worth considering. Just be sure to talk with a real estate agent who can explain local codes and regulations for this type of housing and what’s available in your area.
