Quick Answer
Multigenerational homes in Boise can give families a practical way to live closer together without everyone giving up privacy or independence. The key is finding a property with the right combination of separate living space, kitchens, bedrooms, entrances and shared areas. Moreover, families considering this approach should define exactly what they need before beginning the search.
Summary
For many Treasure Valley families, housing decisions are becoming less about simply finding a bigger house and more about finding a home that works for several generations. Parents may want to be closer to children and grandchildren, while adult children may need additional space without taking on the cost of separate housing.
That is creating more interest in multigenerational housing, including homes with attached or detached ADUs, private suites and flexible floor plans.
Are Multigenerational Homes in Boise the Right Move for Your Family?
A recent conversation with a Boise homeowner highlighted a situation becoming increasingly relevant for families throughout the Treasure Valley: moving closer to family while creating enough independence for everyone to enjoy the arrangement.
In this case, the homeowner was considering a move to the Portland area to be closer to family and a young grandson. Instead of simply looking for another house, the family wanted a home that could accommodate multiple generations while still providing separate living areas.
That distinction matters.
What Is a Multigenerational Home?
The term multigenerational home is different from multifamily housing. Multifamily generally refers to properties such as duplexes, triplexes or fourplexes. Meanwhile, multigenerational housing is designed for related family members from different generations to live together.
The distinction is important when working with an agent because it changes the type of property being searched for.
For example, a family might want a traditional home with a detached ADU. Another family may prefer an attached suite with its own entrance, kitchen and primary bedroom. Similarly, an existing home with a split-bedroom floor plan could potentially be adapted to create greater separation.
Nationally, this is more than a niche housing preference. NAR reported that multigenerational purchases reached 17% of home purchases in its 2025 report.
Privacy Can Make or Break the Arrangement
The most successful multigenerational homes usually balance togetherness with personal space.
That could mean separate kitchens, separate entrances, private bedrooms and bathrooms, or even a physical door separating one portion of the house from another.
Consequently, buyers should think beyond square footage. A 2,500-square-foot home does not automatically work better than a smaller property if the floor plan provides no practical separation.
Realtor.com research also shows that features such as in-law suites, secondary kitchens and dual entrances are common characteristics of homes marketed for multigenerational living.
Boise Families Have Options Beyond Buying a Perfect House
One of the biggest misconceptions is that buyers need to find a property that checks every box immediately.
Instead, there may be several paths.
A buyer could purchase a home already designed for multigenerational living. Alternatively, they could find a conventional home with the right lot and explore whether an attached or detached ADU could work.
However, zoning, permits, construction costs and property layout all matter. Therefore, buyers should investigate those issues before assuming an addition will be simple.
Boise has continued approving ADU projects, and recent city development data shows that ADUs remain part of the area’s evolving housing landscape.
Selling Your Boise Home Doesn’t Always Have to Happen First
The conversation also illustrates another important strategy for homeowners who are financially positioned to move without selling immediately.
If the next property can be identified and purchased first, the homeowner may have more flexibility when preparing the existing property for sale.
That can make the selling process considerably easier. Personal belongings can be moved out, the home can be staged, professional photography can be completed, and the property can be marketed without the owner having to live through every showing.
Ultimately, preparation matters because buyers need to be able to picture themselves living in the property. Professional staging and strong photography can help create that emotional connection.
For homeowners considering a sale, understanding how much your home is worth is an important first step, but an automated estimate should not replace a detailed analysis of comparable properties, condition and location.
Timing Matters in the Treasure Valley
Timing should also be part of the conversation.
The transcript highlights the importance of considering the spring and early-summer buyer pool, particularly for families working around school calendars. Historically, that period can provide a larger pool of buyers who want to move during the summer.
However, the right timing is ultimately different for every seller.
A paid-off property, available equity and the ability to purchase before selling can create options that another homeowner may not have. Therefore, the best strategy should be based on the seller’s financial position, destination, property condition and desired timeline rather than simply choosing a month from a calendar.
Boise Is Still About Lifestyle, Too
Real estate decisions are rarely just financial decisions.
For longtime Boise homeowners, the appeal may include familiar neighborhoods, nearby schools, access to outdoor recreation and the lifestyle that comes with living in the Treasure Valley.
The Boise River Greenbelt, for example, stretches for nearly 25 miles and provides opportunities for walking, running and cycling throughout the area.
Similarly, longtime homeowners may have decades of memories tied to a property. Selling that home can be an emotional transition, especially when it has been where children grew up.
That is why a move closer to family can be about much more than square footage or price.
Bottom Line
Multigenerational homes in Boise can offer families an appealing middle ground: living together while maintaining independence.
Whether that means an attached ADU, detached guest house or carefully designed floor plan, the right property starts with clearly defining how each generation wants to live.
Moreover, homeowners considering a move should plan both sides of the transaction—the purchase of the next home and the eventual sale of the current one.
The goal is not simply to find more space. It is to create a housing arrangement that makes everyday life easier for everyone involved.
FAQs
What is a multigenerational home?
A multigenerational home is a property designed or adapted so relatives from different generations can live together while maintaining some degree of independence. Unlike a multifamily property such as a duplex or triplex, the occupants are typically members of the same family. Common features include an ADU, separate entrance, private kitchen, additional primary suite or distinct living area. Nationally, multigenerational households represent a meaningful portion of the housing market, and recent research shows continued interest in homes with features such as guest houses, in-law suites and secondary kitchens.
Are multigenerational homes becoming more popular in Boise?
Yes, multigenerational living is becoming a more prominent housing consideration, although the available inventory varies by neighborhood and property type. Nationally, NAR reported that multigenerational purchases reached 17% of home purchases in its latest generational trends research. In Boise and the broader Treasure Valley, buyers may encounter existing homes with flexible floor plans as well as properties where an ADU could potentially provide additional living space. Buyers should evaluate the specific property, zoning and feasibility rather than assuming every home can accommodate a separate suite.
What should I look for in a Boise multigenerational home?
Look first for separation and functionality rather than simply counting bedrooms. A private kitchen, bathroom, entrance, living area and bedroom can make a significant difference. Meanwhile, a layout that allows family members to share common areas when they want to can preserve the benefits of living together. Lot configuration is also important if an ADU is being considered. Finally, buyers should investigate zoning, permitting and construction requirements before making an offer based on a future addition.
Is an ADU or attached suite better for multigenerational living?
Neither option is automatically better because the right choice depends on the family. A detached ADU can provide the greatest physical separation and privacy. An attached suite, however, can make daily interaction easier while still providing distinct living areas. Some families may also find that an existing split-bedroom floor plan meets their needs without constructing an additional structure. Ultimately, the best solution is the one that balances privacy, accessibility, cost and how the family expects to use the space over several years.
Should I buy the next home before selling my Boise property?
Buying before selling can be advantageous for homeowners who have the financial flexibility to carry both properties temporarily. It allows the family to find and settle into the next home before preparing the existing property for sale. However, this strategy is not appropriate for everyone because carrying two properties can create additional financial obligations. Therefore, homeowners should review their equity, cash reserves, financing options and expected selling timeline before deciding. A property-specific market analysis can also help determine whether waiting to sell creates a meaningful advantage.
