In 2026, multi generational living is not just practical. It is smart financial planning.

Here is what buyers need to know.

Why Multi Generational Homes Are in High Demand

Several factors are driving demand:

• Aging parents moving closer to family

• Adult children returning home temporarily

• Families consolidating housing expenses

• Buyers planning ahead for long-term flexibility

Franklin’s strong schools and stable neighborhoods make it ideal for extended family living.

What Counts as a Mother in Law Suite?

Not every bonus room qualifies.

A true mother in law suite typically includes:

• Private bedroom

• Full bathroom

• Separate living area

• Kitchenette or full kitchen

• Private entry, ideally

• Dedicated HVAC or separate thermostat

The more independence the space offers, the stronger the long-term value.

Detached Guest Houses vs Attached Suites

Detached Guest Houses

Detached guest homes or carriage houses offer:

• Complete privacy

• Strong resale appeal

• Potential office or rental flexibility

• Clear separation between households

They are more common on acreage properties and in higher price ranges.

Attached Suites

Attached suites are typically:

• Above garages

• Walk-out basements

• First-floor private wings

• Converted flex spaces

They are more affordable but still highly functional.
