For many families, the traditional household is changing. Adult children may return home while saving for their own property, aging parents may prefer to live closer to family, or multiple generations may choose to share a home for financial, practical, or personal reasons.

Whatever the circumstances, multigenerational living can offer meaningful benefits, including stronger family connections, shared household expenses, and greater opportunities to support one another.

The key is finding a home that brings everyone together while allowing each generation to maintain its own comfort, privacy, and independence.

Why families consider multigenerational living

There are many reasons families may choose to share a home:

Stronger family connections

Enjoy more time together, shared experiences, and closer relationships across generations.

Financial flexibility

Sharing housing costs, utilities, and other household expenses may make homeownership more affordable.

Supporting aging parents

Provide a convenient living arrangement that allows older family members to remain connected to loved ones while maintaining independence.

Adult children returning home

Create space for adult children who may be saving for a home, pursuing education, or navigating changes in employment or relationships.

Shared family responsibilities

Make it easier to coordinate childcare, household activities, and family support.

Planning for the future

Choose a home that can adapt as family circumstances and needs evolve.

Finding a home that works for everyone

Successful multigenerational living often depends on choosing the right floor plan. Features worth considering include:

Separate living areas

Private suites, guest quarters, or dedicated spaces where family members can relax independently.

Multiple primary suites

Bedrooms with private bathrooms that provide comfort and privacy for different generations.

Single-level accessibility

Ground-floor bedrooms and bathrooms that accommodate family members who prefer to avoid stairs.

Separate entrances

When available and permitted, private entrances can provide additional independence.

Flexible floor plans

Bonus rooms, home offices, or adaptable spaces that can change as family needs evolve.

Additional kitchens

Kitchenettes or secondary kitchens, where permitted, can make shared living more convenient.

Adequate parking and storage

Practical features that become especially important when several adults share a household.

Some homes offer dedicated in-law suites or accessory dwelling units (ADUs), while others can be modified to accommodate extended family.

A closer look

Accessory dwelling units (ADUs)

An accessory dwelling unit is a smaller, self-contained home on the same property as a primary residence. It typically has its own entrance, sleeping area, bathroom, and kitchen. ADUs are sometimes called in-law suites, granny flats, garage apartments, or guest cottages.

For multigenerational families, an ADU can offer the best of both worlds: family close by, with a separate front door. An aging parent can live independently a few steps away, or an adult child can have a space of their own while saving for the future.

Option 1

Buy a home with an existing ADU

Some properties already include a guest house, garage apartment, or attached suite. Confirm the unit was permitted and approved for living space.

Option 2

Convert existing space

A garage, bonus room, or wing of the home may be converted into a separate living unit, subject to local codes and permits.

Option 3

Build a new ADU

A detached cottage or addition can be built where zoning, lot size, and setbacks allow.

What to verify before you buy or build

✓  Whether local zoning allows an ADU on that specific property
✓  Permits and approvals for any existing unit. Unpermitted space can affect financing, insurance, appraisal, and resale.
✓  Size, height, setback, and parking limits
✓  Owner-occupancy requirements and any limits on renting the unit
✓  HOA, condominium, and deed restrictions
✓  Flood zone and coastal construction requirements
✓  How the addition may affect property taxes and insurance

Example: unincorporated Pinellas County

Under the county's 2024 update, an ADU in unincorporated Pinellas County must have its own entrance, sleeping area, bathroom, and full kitchen. Units may be up to 1,000 square feet, or 750 square feet in coastal storm and flood hazard areas, and the owner generally must live on the property.

The county also offers a property tax assessment reduction when a homeowner builds or renovates an ADU for a parent or grandparent age 62 or older who lives there as their primary residence.

Cities such as Clearwater, Dunedin, and St. Petersburg set their own rules, and ADU regulations change over time. Always confirm current requirements with the city or county and the Property Appraiser.

Before purchasing or renovating, it's important to verify local zoning, permitting requirements, HOA restrictions, and any applicable limitations on separate living quarters.

Balancing togetherness and independence

While sharing a home can offer financial and personal advantages, thoughtful planning is essential.

Families should discuss expectations regarding privacy, household expenses, maintenance responsibilities, shared spaces, and long-term arrangements before making a move.

It's also important to consider how ownership will be structured and what may happen if circumstances change. Financial and legal professionals can help families evaluate arrangements involving shared ownership, contributions toward expenses, or future estate planning.

A successful multigenerational home isn't simply one that has enough room for everyone. It's one that supports healthy relationships while respecting the independence of each family member.

Planning your next move

Whether you're welcoming an aging parent, making room for adult children, or combining households to share resources, finding the right property requires balancing space, accessibility, affordability, and lifestyle.

Frequently asked questions

Can parents and adult children buy a home together?

Yes. A mortgage can include more than one borrower, and some loan programs allow a family member who won't live in the home to be a co-borrower. A lender can explain how each person's income and debts will be counted.

How should we hold title?

Common options include joint tenancy with right of survivorship and tenancy in common, which have different results if an owner dies or wants to sell. Choose with an attorney, especially when a parent's funds go into the purchase.

Does a parent moving in affect my homestead exemption?

No. A family member living with you doesn't affect your homestead exemption. If ownership of the home will change, confirm the effect with the county property appraiser.

How does the Pinellas parent and grandparent ADU tax reduction work?

Homeowners who build or renovate living quarters for a parent or grandparent age 62 or older may apply for a reduction in assessed value. The parent or grandparent must live there as their primary residence on January 1, and the application is due to the Property Appraiser by March 1. Check with the Property Appraiser for a complete set of restrictions and requirements.

Can I rent out an ADU?

It depends on local rules. In unincorporated Pinellas County, the owner generally must live on the property, and cities set their own rules on renting. HOA and deed restrictions may also apply.

What if a parent is contributing money toward the home?

Put the arrangement in writing. Gifts and transfers can affect a parent's future Medicaid eligibility, which looks back five years, so review the plan with an elder law attorney first.

One home, more possibilities

The right multigenerational home can provide the opportunity to share more of life's everyday moments while giving each family member the space and independence they value.
