One of the most versatile types of homes, house plans with in-law suites (also referred to as "mother-in-law suites") allow owners to accommodate a wide range of guests and living situations. The home design typically includes a main living space and then a separate, yet attached suite that has all the amenities needed to house guests.

The separation created between the two living spaces means homeowners aren't compromising any of their own luxuries or conveniences when guests are around. These homes are often built for multi-generational families, people who accommodate friends and family frequently, or those looking to rent out a portion of their home.

 

About Mother-in-Law-Suite Plans

As its name suggests, these plans came about as a means for allowing the mother-in-law (or other relative) of a couple to move in with them while maintaining a high level of independence.

These plans typically begin with a standard multi-bedroom house plan for the main residence, which can appear in virtually any architectural style. The suite exists as a separate yet attached unit to the main floor plan, with the specific layout depending on the design of the rest of the building. Some in-law suite floor plans exist as a converted walkout basement or bottom floor (with a separate entrance), with the main family area residing above it. Other layouts place the suite on the side of the home, typically connected via shared walls or a secondary access way into the main living area. Some plans include the guest house space above the garage.

Regardless of the general layout of the home, the in-law suite portion usually includes all of the standard amenities of a standalone unit, such as:

  • A dedicated bedroom separate from the living space or dining area
  • A kitchen area, which can range from a space-conscious kitchenette to a fully functioning room with its own stove and cooking area
  • A dedicated bathroom or half bath
  • A standalone entryway that leads straight outside rather than requiring the occupant to pass through the main part of the house to get in and out of the unit

Whether you have actual in-laws moving in with you, aging relatives, or an older child who seeks more independence, a house plan with a mother-in-law suite from The Plan Collection may be just what you’re looking for.

The In-Law Suite: Say Hello to a Home-within-the-Home


TPC author Rexy Legaspi

The In-Law Suite: Welcome to a Home-Within-the-Home   On an upswing for a number of years, in-law suites have redefined the idea of living together for the modern family. These “homes-within-the-home” are stylish accommodations for in-laws, returning children, or overnight/weekend guests. And, they come in all shapes and sizes - from a garage studio apartment to a first-floor master bedroom, a refinished basement, or a tiny cottage on the grounds of the primary residence.      This spacious 1-bed
