In-law suites are becoming increasingly popular as more people choose to live with extended family members. An in-law suite can provide a separate living space for aging parents, adult children, or other family members. These spaces can also increase the value of a home, as well as provide homeowners with additional rental income should they choose to rent out the space to a tenant (ADUs are a great option for this as well!). Here are 5 of our favorite house plans with multi-generational layouts.

The optional lower level of Plan 800001GDP includes a spacious additional living area that would make an amazing space for in-laws or adult children. The kitchenette and living space are designed with an open layout, and offer access to a lower level patio. An additional bedroom and bathroom are located on the right side of the home. We love the addition of a lower level shop/garage space - perfect for housing an additional vehicle or for equipment storage.

Plan 623134DJ would make an amazing multi-generational family lake house. The home can be built as a single story, which includes 3 bedrooms and an in-law apartment. The optional lower level offers 2,800 sqft of additional living space. A mudroom and porch separate the main house from the in-law suite - each side of the home has a dedicated garage as well. We love the inclusion of a kitchenette to allow for complete privacy between families. This space could also be a great option for guests or adult children.

Plan 33257ZR is a great plan for a wide lot - sitting at almost 112' wide. The owner's and in-law suites are located on opposite sides of the main floor. The in-law suite is secluded just past the laundry room and pool bath. It has its own private patio and full bath with shower and spa tub. Plenty of space for a sitting area and a morning kitchen.
