That spare room on the main floor. The finished basement with a kitchenette and its own entrance. The bonus room you’ve been using for storage. To you, it’s extra space, but to a growing pool of buyers, it’s the reason they would pick your house. Here’s why: multi-generational home buying is on the rise.

Millions of families are living multi-generationally – that’s when three or more generations live under one roof - and that number is only climbing. Data shows those households grew from 3.2 million to almost 4 million between 2014 and 2024 according to Realtor.com. 

Each year, more people are shopping for a larger home that fits their combined needs. While the appetite for this type of house is rising across the board, data shows multi-generational living is more common in some states than in others. Where does your state fall? California, Texas and Hawaii are leading the pack. Massachusetts is at four percent while Connecticut is just under four percent.

Depending on where you are, the pool of buyers looking for a house like yours could be even bigger than you’d think. But the overall bottom line is this: There’s a real market out there for larger homes with room for multiple generations under one roof, especially since affordability is still so tight. If you own a house like that, it’s in demand.

Multi-generational houses sell at a premium and that extra room carries real value with the right buyer. According to Realtor.com, in 2025 the median asking price for a multi-generational house was $709,000, roughly 65 percent higher than the $429,900 median for a standard house. Some of that is simply size. But compare multi-generational homes to regular homes with the same amount of square footage, and they still come out on top – $262 per square foot versus $215. That’s a 22 percent premium you could command for special features like in-law suites, second kitchens, and separate entries.

When you sell, this could help you walk away with more money in your pocket, especially when your agent highlights your home’s multi-generational features in your listing. And even with slightly higher price tags, buyers aren’t getting sticker shock. Multi-generational houses drew 13.5 percent more online views than standard ones, and they still sold just as fast – in about 59 days – per the same Realtor.com report.

Basically, when buyers want something that’s very specific, the house that checks the boxes tends to stand out. Your multi-generational-friendly, or simply larger-than-average, house might meet criteria a lot of buyers can’t find in a standard one. That’s what gets attention and offers.
