The Long Island Multigenerational Housing Boom: In-Home Training Solutions for Three-Generation Households in 2025

When Three Generations Share One Roof: How Long Island’s Multigenerational Housing Boom is Creating New Challenges for In-Home Dog Training

Long Island is experiencing an unprecedented housing transformation. With the increased cost, more and more families are living multigenerationally to pool resources. Properties with separate living areas, such as in-law suites or finished basements, become increasingly desirable—especially in Suffolk County, where larger lot sizes can accommodate such configurations. This shift isn’t just changing the real estate landscape—it’s creating entirely new dynamics for families and their four-legged companions.

The numbers tell a compelling story. The number of Americans living in a multigenerational household with three or more generations has nearly quadrupled over the past decade, with a dramatic increase of 271 percent from 2011 to 2021 (7 percent vs. 26 percent). Generations United estimates 66.7 million adults ages 18+ in the U.S. are living in a multigenerational household; that’s more than 1 in 4 Americans. On Long Island specifically, there’s an increasing trend towards multigenerational homes and properties with extensive outdoor amenities, driven by both economic necessity and changing family values.

The Perfect Storm: Multiple Generations, Multiple Dogs, Multiple Challenges

When grandparents, parents, and adult children all live under one roof, the household dynamics become exponentially more complex—especially when dogs are involved. The greatest need for multigenerational families is appropriate and affordable housing. With several generations under one roof, the issue of privacy can be challenging. However, the ability to find affordable housing is a critical issue for many people these days.

Each generation often brings their own pets, creating what experts call “multi-dog households” within an already complex family structure. Training more than one dog at once is challenging, but with the right techniques you can have a well-behaved multi-dog househould. But dogs are a serious responsibility, too, and the more dogs you have, the greater the challenge to care for them, especially when it comes to training.

The challenges multiply when you consider that different generations may have vastly different approaches to pet care and training. Grandparents might prefer gentler, old-school methods, while tech-savvy millennials might want to use the latest positive reinforcement techniques. Meanwhile, the middle generation—often the primary decision-makers—finds themselves mediating not just between family members, but between conflicting training philosophies.

Why In-Home Training Becomes Essential

Traditional group training classes simply don’t address the unique dynamics of multigenerational households. While the joy of dog ownership/fostering grows with each new ‘family’ member you add, the challenges of managing the household can also increase. Bringing a new dog into the family is an exciting time for everyone but can create stress for your resident canine.

In-home training becomes crucial because it allows professional trainers to observe and address the specific environmental factors at play. Issues like resource guarding become more complex when multiple generations are feeding different dogs at different times, or when grandchildren might unknowingly trigger protective behaviors in family pets.
