What Is a Mother-in-Law Suite? Modern Guest Suites in Central KY

As families grow and change, homes must adapt. A mother-in-law suite is one time-tested solution for adding space or accommodating multiple families living together. You may be wondering what a mother-in-law suite is and how it differs from a guest suite. As experienced contractors, we are here to explain what a mother-in-law suite, how it differs from an accessory dwelling unit (ADU), is and what to look out for when building additional living space onto your home.

Difference Between a Mother-In-Law Suite, a Guest Suite, and a Full ADU

First off, what exactly is a mother-in-law suite, and what makes it different than any other kind of guest suite? A guest suite is usually just a bedroom in one’s home where guests can stay, or it might even be an entire floor, like a basement or loft, that has been outfitted for people to live in, short- or long-term.

For many people, the concept of a mother-in-law suite goes a step further than a guest suite. It’s a more private fully functional living space—usually with its own entrance, a dedicated sleeping area, a bathroom, a kitchenette, and a living area—built within, attached to, or beside the main house for a family member to live in comfortably. This offers everyday privacy and separation while keeping loved ones close.

A full accessory dwelling unit (ADU) is the most independent option of all. An ADU is a self-contained second home on the same property, with everything a standalone residence has: a full kitchen, a bathroom, sleeping and living areas, and a private entrance. What separates a full ADU from a basic suite is that it meets local zoning and building codes as a distinct dwelling, which often means it can be rented out and may carry its own utilities and address. 

Put simply, any full ADU can serve as a mother-in-law suite, but not every mother-in-law suite is built to full ADU standards. Because those requirements vary by city and county, it’s worth confirming what your local code allows before breaking ground.

Mother-In-Law Suite Layouts

When it comes to planning additional guest housing in your living space, whether they’re seasonal visitors or independent residents like parents or adult children, homeowners should choose a layout that matches their needs for connection, privacy, and follows and local code and planning constraints. There are many options to add this additional space to a floor plan that include different levels of investment.

• Home renovation: Levels of investment differ from simple room renovations to full remodels that add square footage to your home’s footprint and offer different levels of shared space and unit access.
• Attached suite: Built to share a structural wall with your existing home.
• Basement or Garage Conversion: Converting an existing upper or lower level to transform existing space into something much more functional.
• Detached suite: Ideal for those who want ample privacy and independent while still sharing property.
