Mother’s Day is here and it’s a day we give our moms a little extra attention. But, as our parents age, celebrating mom just one day a year may not be enough. Luckily here’s a new trend in housing that keeps our parents an active part of the family and the attention they deserve: “mother-in-law” or “in-law” suites.

Three Generations of Women


Mother-in-law suites are whatever you need them to be. Bed and bath additions to a home, converted rooms, free-standing apartments or in home suites. What they all have in common is their preferred location on the ground floor for accessibility and their added sales appeal (generally they increase property value, but by how much depends on the kind of addition you create and can be up to 60%). The additional space can also be used outside of in-law housing and can be purposed as an office, living space for recuperating relatives or serve as a guest bedroom until you yourself no longer wish to tackle the stairs.

Multigenerational housing is increasing yearly, and professionals agree: it’s best to start thinking of the future of your parents and in-laws (even your own) now rather than when you need to. They’re perfect for living situations between relatives who want to keep their privacy and save some independence while also feel included in the rest of the household. If creating these mother-in-law additions seems to be in your future, then consider these seven tips before you build.

1. Check Building Area Codes

Before you begin, check with your city on building area codes because this can limit what you can do with your addition. Most zoning rules limit additions to having a bedroom, bath, sitting area and kitchenette. You can get around the kitchen problem by installing a wet bar or making sure the addition has access to the communal kitchen. Adding a kitchen or creating a free-standing unit makes it an AUD (affordable dwelling unit) which is considered rentable—this makes your home no longer a single-family home and requires separate permits.

2. Check Your Septic Permit

You don’t really think about it, but if you have a septic tank you also have a permit for it. There are many rules we often don’t have to think about when it comes to our plumbing, but many septic tanks can only allow for three bathroom connections. There’s a chance you may have to increase the size of your system to allow for an addition with a bath, which means increased costs to prepare for.

3. Choose a Location

With the type of space you want to build in mind, it’s time to look around your home for the best place to build or convert. Permits permitting, you can transform your garage or porch area to an enclosed dwelling. If you’re looking to create a new addition to your house, look for an area along the first floor next to a room you underutilized and can use a space near an existing bathroom. If you convert existing rooms, you can combine two rooms to make a suite: think formal dining and living areas you use only for guests, etc. Now they can house more permanent guests.

4. Separate Power

You may want to consider keeping your addition on its own separate power, heat and A/C source. It will help in the future should you decide to charge an occupant rent, but more importantly, you can shut the unit down when it’s not being lived in.

5. Keep Occupants in Mind

When laying out the blueprints for your addition and choosing what kind of addition to create, keep the ones who will be living there in mind. Will they need wider doors and hallways? Assisted baths with lever handles and stylish guardrails? No slip-flooring and no-curb showers? Even if your parents or in-laws are physically active now, they may need help from time to time in the future. This also goes for how much privacy and independence they desire. If you want to spend a lot of time together, maybe you can forgo a kitchen or sitting area and share the communal ones. Or maybe they would prefer an entirely separate living arrangement. It’s up to your family.

6. Keep Others in Mind

If your relatives aren’t planning to move in permanently or they won’t move in for a while, it’s important to keep everyone in mind with the decor of your addition. Keeping things neutral, from flooring to curtains to wall color, will allow whoever lives there to add their personal touches on top of this basic groundwork.

7. Enjoy Your Family

Having a parent move in with you may seem daunting at first, but many families who are interviewed say it’s been a blessing and many wish they’d done it sooner. Sure there are the logistical benefits of cut care costs, but the biggest benefit is spending more time with your entire family and taking care of those who once took care of you.
