ADU stands for accessory dwelling unit

What is an ADU exactly?

It is an abbreviation for Accessory Dwelling Unit or, more commonly known as a secondary living space on your property—either detached (like a small backyard cottage or above-garage apartment) or attached (like a finished basement or converted portion of your existing home). It’s fully self-contained, with its own entrance, kitchen, bathroom, and sleeping area.  It also means "farewell" in French if you say it right (adieu).

At our recent “Forever Home” seminar, we explored what it means to stay in your home safely, comfortably, and with confidence—for as long as you can. One concept that resonated with many attendees was planning not just for your own aging journey, but also for your parents and loved ones who may one day need support.

As more homeowners in their 40s and 50s begin to navigate these transitions, we’re seeing increased interest in Accessory Dwelling Units (ADUs) as a flexible, forward-thinking solution. Whether it’s a space for aging parents, a future caregiver, or even a rental for supplemental income, an ADU is one of the most powerful tools available for building your Forever Home.

What could you do with an adu?

Why ADU's Can Make Sense for Midlife Homeowners Here are a few reasons ADUs are gaining traction:

  • Support Aging Parents: An ADU allows a loved one to live nearby, while maintaining privacy and dignity—far more comfortable and personal than an assisted living facility.
  • Plan for Your Own Future: The space can easily convert into a caregiver’s quarters when you need support, or your own retreat if mobility or health needs change.
  • Generate Rental Income: Depending on your city’s zoning, you may be able to rent out the space for extra income during the years you’re not using it personally.
  • Boost Your Property Value: A well-designed ADU adds significant value to your home, especially as multigenerational living becomes more common.

Its mostly about universal design

Thoughtful Design Is Key 

Designing an ADU isn’t just about building a small house—it’s about building the right kind of space. Our design/build team specializes in universal design principles, ensuring spaces are beautiful, comfortable, and accessible now and into the future.

That means:

        • No-step entries and wider doorways
        • Accessible kitchens and bathrooms
        • Smart lighting and safe flooring choices
        • Efficient layouts that feel open and livable

Whether you’re thinking about your parents, your partner, or your own future self, designing with intention now pays dividends later.

There are important differences between ADU's & tiny houses

Is an ADU the same as a "Tiny House"? 

No. The so called "tiny house", which technically is also a secondary dwelling unit, has several key differences:

Legal Definition and Zoning: ADUs are typically legally defined and regulated by local zoning laws and building codes as a secondary dwelling unit on a single-family residential property. They can be attached to the main house, such as a basement apartment or above-garage unit, or detached as a separate structure.

o   Tiny Houses: These are often considered more as movable or portable homes. They may or may not be subject to the same zoning and building regulations as traditional ADUs, depending on whether they are on wheels (considered RVs in some areas) or on a permanent foundation.

Size and Purpose:

o   ADUs: They are usually designed to be a permanent living space, often with amenities like plumbing, electricity, and heating, meeting local residential building codes.

o   Tiny Houses: These can vary widely in size but are generally smaller than typical homes. They may be designed for mobility or compact living and can serve as full-time residences or vacation homes.

Construction and Placement:

o   ADUs: They are constructed with more stringent building codes and standards due to their intended use as permanent living spaces. They must comply with local building permits and zoning regulations.

o   Tiny Houses: Depending on their classification (permanent structure vs. movable), they may have different construction requirements. Movable tiny houses often have lighter building codes, while those on foundations are subject to traditional building codes.

 Utility Connections:

o   ADUs: They are typically connected to the main utilities of the primary residence (water, sewer, electricity), making them functionally independent dwellings.

o   Tiny Houses: Depending on their mobility and design, they may have varied utility connections, from fully self-sufficient (off-grid) to needing to hook up to utilities where permitted.
