Overall, building an in-law suite can be a smart investment for homeowners who weigh the costs and benefits and plan for the long-term. With the potential for rental income and increased property value, it can provide a comfortable living space for family members while also generating additional income.
Approximately 500 to 700 square feet is a good size for an in-law apartment or addition.
Adding 1000 square feet to your home can be a significant investment. The cost typically ranges from $125,000 to $250,000. This wide range is due to several factors: Materials and Finishes: Basic materials will keep costs lower, while high-end finishes can drive up the price.
On average, an in-law suite can increase your home's value by 20% to 30%, depending on where you live and the quality of the addition.
Building a mother-in-law suite could also offer certain tax benefits. How many square feet is a typical mother-in-law suite? Mother-in-law suites can vary in size but are typically about 500 square feet.
Generally, building up is usually more cost-effective for new construction, while building horizontally tends to be less expensive for remodeling existing homes.
The foundation and framing are usually the most expensive parts of a home addition. Both are essential for a safe and sturdy structure, and you have limited options for cost-cutting. Labor costs can also be significant, especially for complex projects.
There may be tax credits for having an ADU or in-law suite. For instance, if you're paying for more than half of your relative's support, you may be able to claim them as a dependent. You may also qualify for a home office tax deduction if that's the in-law suite's primary use.
In-Law Suite
Converting a garage into a full in-law or guest suite—or a guest house in the case of a detached garage—costs $20,000 to $50,000 on average. At the lower end of the range, a basic conversion will include insulation, drywall, flooring, and a bathroom.
Because renting out an in-law unit is legally equivalent to renting out any other piece of property, you do need to follow the laws of your local municipality, Stephens says.
A mother-in-law unit is often integrated into the main house. That means it may not have its own entrance like other ADUs. The square footage of an ADU is not added to the square footage of the main house. Most mother-in-law units are part of the overall house and added to its square footage.
The overall cost of a room addition is influenced by several factors including location, materials, labor, and permits. Typically, homeowners can expect to spend between $10,000 to $25,000 for a basic 10x10 room addition, but this can vary widely.
Bump-out additions (also known as micro additions) extend the size of an existing room in your home, often by just a few feet (although they can go up about 15 feet). Compared to other types of home additions, bump-outs are smaller in size, take less time to build, and are more affordable.
The estimate we give our clients is to expect 3-4 months or more for an addition of 1,000 square feet. A smaller addition of 200-400 sq. ft. will take 2-4 months. This is just an estimate, of course, and the exact time will depend on the factors listed above.
Prefab homes: Modular or manufactured homes are more affordable because their structures are partially built off-site, rather than building a fully custom house on-site. Tiny homes: A tiny home may be the cheapest type of house to build.
