Multigenerational homes are increasingly popular among US families. Therefore, more and more Americans are opting for constructing extra living quarters so their aging parents can move in.
This additional attachment to the house or a separate dwelling within the property is called an in-law suite. Apart from creating a comfortable haven and a private space for your mom or dad or both, an in-law suite also increases the value of your home. It enhances the appeal of your property to prospective home buyers in the real estate market. You can build an in-law suite in your backyard, garage, shed, attic, or any underutilized rooms as long as you can accommodate a bedroom, sitting room, bathroom, and a kitchen area.
Here are some possibilities with their approximate building cost:
- Garage conversion - $20,000 to $65,000
- Basement conversion - $10,000 to $27,000
- Attic conversion - $40,000 to $90,000
- Upcycling an unused room - $2 to $4 per square foot (framing a wall) plus $3,000 to $25,000 (adding a bathroom)
Legal requirements for adding an in law suite
There are no uniform set of building standards or rules when it comes to constructing an in-law suite. The requirement for a building permit depends on a number of factors, including the size of the mother-in-law suite, its location, and whether it involves major structural changes.
You will have to find the laws specific to your property and pin code. It’s best to visit your zoning office before constructing such a suite on your property.
Since these secondary units are self-contained with a separate entrance, kitchen, and bath, they can be rented out -- provided they are legal and meet the building standards. Renting out a mother-in-law unit is legally equivalent to renting out any other property. Keep in mind that you will have to follow the local laws of your municipality.
However, before renting out your in-law unit, you need to be prepared mentally for a tenant in your personal space. So, weigh the pros and cons before you think of subletting this unit.

- Hire a remodeling expert. A professional will ensure that all permits, zoning regulations and inspections are up to date.
- Check your area’s septic permit requirements. You may have to increase the size of your existing system to allow for an addition with a bathroom.
- List out your all your requirements. These could include dedicating the right amount of space for a living room, a comfortable size bedroom, a bathroom with a large tub or a curbless shower, a kitchen and possibly a dining room.
- Choose the right location for the in-law suite. You can transform your garage or porch or, if you’re looking to create a new addition to your house, zero in on the most convenient location.
- Consider having your mother-in-law suite on its own separate power, heat, and AC sources.
- Seriously think about accessibility, such as adding ramps and wider doorways and hallways.
- Consider installing assisted baths with lever handles and stylish guardrails.
- Keep things neutral – from the flooring to the curtains to the wall color. That way, whoever lives there can add their own personal touches.
- If you’re on a tight budget or timeline, plan your remodeling project for the winter to avoid the spring and fall rushes.
- Get a written contract from your contractor detailing the complete schedule along with a guarantee.
- Discuss and mutually agree on the payment schedule.
