What Is A Mother In Law Suite?

This type of house plan usually involves separate living quarters for another family member. These quarters are often a part of a converted attic or garage, or sometimes even the basement. They usually consist of a bedroom, a kitchen or kitchenette, a bathroom, and even a living room. They aren’t normally larger than average houses. It enables a family member or friend to live with you while still ensuring that they have their own private space. There are a number of different house plans with mother in law suite that you will be able to choose from. Here’s a deeper dive into what types of mother-in-law house plans you might find:

  • Guest house plans are a great option for mother-in-law suite as they offer a separate space for guests. These are not attached to the home, so there will be a separate entrance, specifically to that house. This reduces noise and friction when a lot of adults are living together. The guest house will have a kitchen, bathroom, living space, and one or more bedrooms. Guesthouses help to reduce conflict, while still keeping the guest close to the main house.

  • Converted Garages or Attics. Building mother-in-law suites in the garage, attic or basement will need to have plumbing. If you are adding on to an existing home, this could cause considerable costs. So make sure to do your research to find what will work best for you. 

  • Connecting Suites. Another option that you can go with is a one story house plan with connecting in-law suite. These types of suites are attached to the home. There is usually only one entrance into the suite. So the main front door is the one that everyone will use at the home. The connecting suites will have full-service kitchens, bathrooms, bedrooms, and a living room area. These house plans with mother-in-law suite offer the best of both worlds, giving the person living in this area. Also, plenty of autonomy, but putting them much closer to the rest of the people living in the main residence. This is another good option for elderly people who need to be close to everyone else but want to keep some of their independence.

If you want to build a home that can accommodate a multi-generational family without breaking the bank, you can definitely do so with a mother-in-law suite. Start researching now, and you can find the right one to suit you and your family’s needs.
