More Massachusetts families are choosing multigenerational living. Whether it’s to provide support for aging parents, reduce long-term care costs, or simply stay close as a family, an in-law suite can be a smart and meaningful investment.
But designing an in-law suite for aging parents requires more than adding square footage. It requires thoughtful planning that balances independence, safety, comfort, and long-term flexibility.
Here’s what to consider.
1. First-Floor Living Is Ideal
Whenever possible, locate the in-law suite on the first floor. Eliminating stairs improves safety and ensures the space remains functional for years to come.
If the suite must be above a garage or on a second level, planning for:
- Wider stairways
- Strong handrails
- Potential future lift options
can help future-proof the design.
2. Prioritize Accessible Bathroom Design
Bathrooms are one of the most important spaces to design correctly from the start.
Features to consider:
- Curbless or low-threshold walk-in showers
- Built-in bench seating
- Grab bar blocking installed behind walls (even if not immediately needed)
- Comfort-height toilets
- Wider doorways (32” minimum clearance)
Even if parents are fully mobile today, planning for tomorrow avoids costly renovations later.
3. Open Layouts with Good Lighting
As we age, natural light and clear sightlines become more important. Open-concept living areas reduce tripping hazards and make the space feel larger and more inviting.
Include:
- Large windows
- Layered lighting (overhead + task lighting)
- Lever-style door handles
- Minimal thresholds between rooms
4. Sound Separation and Privacy
One of the keys to successful multigenerational living is privacy.
Design considerations include:
- Separate entrances when possible
- Sound-insulated walls and ceilings
- Independent HVAC zones
- A small kitchenette for autonomy
Parents often value independence just as much as proximity.
5. Storage and Everyday Convenience
Small details matter:
- Laundry access (in-suite or nearby)
- Easy-to-reach shelving
- Ample closet space
- Dedicated parking close to the entrance
These features improve day-to-day living without making the space feel institutional.
6. Think Long-Term Flexibility
Even if the suite is designed for aging parents now, it may serve different purposes in the future — guest space, adult children returning home, or resale value.
In many Massachusetts communities, a well-designed in-law suite or ADU can increase property appeal and marketability.
Planning in Massachusetts
Every town has zoning and permitting requirements that influence layout and square footage. Working with a design-build team familiar with local regulations ensures the project meets both family needs and municipal guidelines.
Designing an in-law suite for aging parents in Massachusetts is about more than construction. It’s about creating a space that supports dignity, independence, and family connection for years to come.
