Would you consider living in a multigenerational household to manage housing costs?

The percentage of the U.S. population living in multigenerational households grew to 22% in 2024, driving developers to create homes designed for aging parents and adult children. Builders are now launching specialized communities, such as Lennar's 103-lot Greenview at Presidential in Miami.

Why it matters

Rising housing costs have prompted more families to consolidate households to share expenses and living space. This trend has established a 22% price premium for homes marketed with specific multigenerational features.

Nationally, families pay a 22% premium for homes marketed as multigenerational. Lennar's new Greenview at Presidential community in Miami features 103 lots with floorplans ranging from 2,100 to over 3,900 square feet, priced between $2.5 million and $3.5 million.

The players

Lennar

A major homebuilder known for its nationwide construction projects and proprietary multigenerational floorplan designs.

PulteGroup

A national homebuilding company that recently expanded its residential offerings to include dedicated multigenerational housing concepts.

The details

Next Gen floorplans integrate a self-contained living suite on the first floor to provide privacy while maintaining access to the main residence. These designs allow adult children or extended family members to live independently within the same building footprint. Competing developers, including PulteGroup, have also entered this space, introducing their own AllGen home concepts in 2025 to meet shifting family logistics.

Timeline

  1. 2010: 16% of the U.S. population lived in multigenerational households.

  2. 2020: 19% of the U.S. population lived in multigenerational households.

  3. 2024: 22% of the U.S. population lived in multigenerational households.

  4. 2025: PulteGroup introduced the AllGen home concept.

The Home Front

The rise of specialized home designs follows a clear demographic trend showing that multigenerational living has become increasingly common over the last 15 years. This shifts the housing market away from traditional single-family layouts toward homes that prioritize shared financial and family logistics.

If you are planning to accommodate extended family, evaluate whether your current floorplan allows for a private suite or requires a renovation to create independent living zones. Before moving forward, consult with a licensed contractor to assess if your home's layout supports the necessary structural and plumbing adjustments for a dedicated suite.

The takeaway

The move toward shared living is a significant shift in how families manage rising costs and housing needs. Homeowners should track local zoning laws if they plan to add independent living structures, as these regulations often change when a property is converted for multiple generations.
