House plans with mother in law cottage

At Family Home Plans, we have many house plans with in-law suite options. Different types to consider include:

  • Attached to the main home: For easy access to the in-law suite, you may want to have it attached to the main level of your home. This is a good option if you are caring for a parent who needs assistance regularly or who has mobility issues.
  • Separated from main home: If your parent is more independent, you could consider a plan where there is some separation from the rest of the house. This could be a suite that is above a garage, on a different level or even just separated by a hallway or breezeway.
  • Floor plans with in-law suite: An in-law suite can be more than just an additional master bedroom. Depending on the person's level of independence, you can choose floor plans that create more of an apartment-like feel. You can incorporate features such as a kitchenette, living room and private entrance.

With our variety of home plans, you'll be able to find the perfect in-law suite option.

Finding the Right House Plans With an In-Law Suite

As you search for the right home plan with an in-law suite, here are some things to think about:

  • Who will be using the in-law suite?: Will it be a mother-in-law suite or a suite for both parents? What are the needs of the person who is living there? How well can they get around? This will help you determine the best layouts to consider.
  • Where in the home do you want the in-law suite?: How separate do you want the suite from the main home? What is the balance of privacy and accessibility you are hoping to find?

As the population ages, more families will become caretakers for elderly parents or relatives. These house plans with in-law suites offer the needed space (often on the first floor, ideal for a person with limited mobility). Of course, in-law suites can be used by buyers in many different situations, from owners who simply want comfortable guest accommodations to those with nannies or live-in caretakers. The suites themselves range from a simple bedroom and bathroom to more elaborate apartments suitable for semi-independent living (older children, perhaps returned from college and looking for a job, will especially appreciate the latter type). Some of these suites are even detached for the home for greater privacy. Either way, a house plan with an in-law suite offers outstanding versatility for the future. Adding onto an existing home? Consider one of our garage plans with apartments.
