What to Consider When Building an In Law Suite

What to Consider When Building an In Law Suite


March 29, 2024

Understanding In Law Suites

Adding an in law suite to your home, whether as new construction or a home extension, not only enriches your living space but also boosts your property’s functionality and value. This guide merges insights into optimal sizes, strategic floor planning, legal considerations, and practical aspects like location, privacy, and utilities integration. An in-law suite, legally known as an “accessory dwelling unit” (ADU), offers a private space within your home to host extended family with the independence they need. Its versatility makes it perfect for aging parents, grown children, or as a potential rental space, enhancing both the utility and financial value of your property.

Optimal Sizes and Floor Plans for an In Law Suite

What is the best size for an in-law suite?

The best size for an in-law suite varies depending on the needs of its occupants and the available space within or adjacent to your existing home. However, functionality should be the guiding principle.

How many square feet is a typical mother-in-law suite?

A typical mother-in-law suite ranges from 300 to 1,000 square feet. Smaller suites might resemble a studio apartment with an open-plan bedroom and living area, while larger ones can include multiple bedrooms, a kitchen, and a living room.

When considering in-law suite floor plans, it’s essential to include at least one bedroom, a bathroom, a small kitchen, and a living area. The layout should promote accessibility, perhaps with wider doorways and no-step entries to accommodate mobility aids if necessary.

Investment and Legal Considerations

Is a mother-in-law suite a good investment?

Adding an in-law suite can increase your home’s market appeal and value. It offers potential rental income and makes your property attractive to a broader range of buyers. When planning this addition, consulting with home extension contractors experienced in new construction with in-law suites can provide insights into maximizing your investment.

What is the legal term for a mother-in-law suite?

The term “Accessory Dwelling Unit” (ADU) is commonly used in zoning laws and building codes to describe a secondary housing unit on a single-family residential lot. Understanding your local ADU regulations is crucial before starting your project to ensure compliance with all legal requirements.

Choosing the Right Location

Location on Your Property

The location of your in-law suite can significantly impact its functionality and the overall living experience. Options include converting a basement, garage, or attic; building an extension to your home; or constructing a detached unit. Each choice has implications for privacy, accessibility, and cost.

Privacy Concerns

Privacy is a critical consideration for in-law suites. Independent access, soundproofing, and strategic layout planning can help maintain a balance between closeness and personal space for both the main household and the suite’s occupants.

Separate Utilities

Implementing separate utilities for the in-law suite, such as electricity, water, and internet, can provide autonomy for its residents and simplify billing processes. This autonomy is particularly appealing if you’re considering renting out the suite or wish to give your family members independence.

Choosing the Right Contractors

Selecting experienced home extension contractors who have worked with homes with in-law suites is vital. They can help navigate the complexities of adding an in law suite, from drafting in-law suite floor plans that meet your family’s needs to ensuring the construction process is smooth and compliant with local building codes.
