An in-law suite—also known as an accessory dwelling unit (ADU) or secondary suite—is a compact living space on the same property as a single-family home, and it’s gaining traction in the Fargo-Moorhead area. Originally designed for aging parents, these versatile spaces are now a hot feature for local buyers, whether or not “Mom” is moving in. At Vision Realty, we’re seeing increased interest in neighborhoods like The Wilds and South Fargo, where these suites add both value and flexibility.

Typically equipped with a bedroom, private bathroom, and sometimes a kitchenette or full kitchen, in-law suites can be attached (e.g., in a basement or above a garage) or stand alone. Locally, they’re often called granny flats or casitas, reflecting the diverse needs of our community. They offer privacy and proximity, making them ideal for multigenerational living, home offices, or even rental income.

What to Know About an In-Law Suite

An in-law suite is a self-contained area that balances independence and convenience. At a minimum, it includes:

• A sleeping area (usually a bedroom)

• A private bathroom

Many local suites also feature a living room or kitchenette, perfect for aging parents, adult children, live-in caregivers, or visiting relatives in the Red River Valley.

Different Types of In-Law Suites

When not housing family, these suites open up a world of possibilities, boosting their appeal as an investment. Here are some local uses:

• Home Office: With remote work on the rise, Fargo-Moorhead buyers are eyeing these spaces for small businesses or quiet workspaces, says Christopher Leigh of Vision Realty.

• Guest Quarters: Ideal for hosting out-of-town visitors during events like the Fargo Marathon, offering them a private retreat.

• Residence for Older Children: A practical solution for young adults starting out, perhaps contributing rent while living in Horace or Moorhead.

• Rental Apartment: Fully equipped suites can generate income through long-term tenants or short-term rentals, a growing trend in West Fargo.

Can I Build an In-Law Suite in Fargo-Moorhead?

Local zoning laws vary, so check with your city or county planning office (e.g., Fargo City Hall or Clay County) using your property details. In some cases, a variance might be needed, potentially requiring neighbor approval and costing up to $500. Building permits are also required, and restrictions may apply—some areas limit kitchens due to fire codes or prohibit rentals unless tied to family use. Vision Realty can connect you with local experts to navigate these regulations.

How Much Does It Cost to Build?

Costs depend on size and location. Adding a suite to an existing home in Fargo-Moorhead typically ranges from $30,000 to $70,000, while a new stand-alone structure might reach $125,000 or more. Vision Realty’s team can help you assess options tailored to your budget and property.

In-Law Suites as a Sales Feature

These suites are a standout feature for buyers and sellers alike. “An in-law suite or its potential can set your home apart in our competitive market,” notes Christopher Leigh. With multigenerational living growing locally, homes in Golden Valley or Prairie Meadows with first-floor bedrooms and baths are marketed as “potential multigenerational suites,” drawing more buyer interest. An open floor plan enhances versatility, appealing to those who might repurpose the space.

Can I Rent Out My In-Law Suite?

Yes, in many cases, but local rules apply. Fargo and Moorhead have specific ordinances—some restrict short-term rentals like Airbnb, while others limit kitchens in ADUs. Check rental laws, ADU permissions, and permit requirements with your municipality. If compliant, a suite can provide steady rental income, a smart move for investors in our region.
