“How to Design an ADU for an Aging Parent”

As we age, our needs change, and ensuring that our living spaces evolve to meet these needs becomes increasingly important. For many families, designing an Accessory Dwelling Unit (ADU) for aging parents offers an excellent solution. Not only does it provide a comfortable, independent living space for seniors, but it also allows families to stay close and provide support when needed. In this blog, we’ll explore the best practices for designing an ADU specifically for aging parents, with a focus on accessibility, safety, and comfort.

Why Build an ADU for Aging Parents?

Maintaining Independence
One of the greatest gifts you can give your aging parents is the ability to maintain their independence while still having family nearby. An ADU offers them the freedom to live on their own terms. They can cook their meals, pursue hobbies, and entertain friends, all within their own space. This setup provides a balance between independence and proximity, allowing you peace of mind knowing they are close but still have their own private area.

Proximity to Family
Building an ADU ensures that aging parents remain close to their family. This closeness facilitates regular check-ins, assistance with daily tasks, and more quality time together. It also benefits younger generations by allowing grandchildren to spend more time with their grandparents and potentially even providing informal childcare.

Increasing Property Value
Investing in an ADU not only addresses immediate family needs but also adds value to your property. A well-designed ADU can serve multiple purposes in the future, such as a guest house, home office, or rental unit. This flexibility makes your property more attractive to potential buyers and can result in a higher return on investment.

Cost-Effective Long-Term Care Solution
Long-term care facilities can be extremely expensive, with costs often exceeding $5,000 per month. In contrast, building an ADU may involve a higher initial investment but can be considerably more economical over time. By investing in an ADU, you’re putting money back into your property rather than paying ongoing fees to a care facility.

Key Design Principles for an Aging Parent ADU

When designing an ADU for aging parents, it’s crucial to plan for both current and future needs. Here are some key principles and practices to consider:

Mobility and Accessibility


Creating a space that accommodates mobility aids and ensures ease of movement is essential.

  • Single-Level Design: Opt for a single-story design to eliminate stairs, reducing the risk of falls and ensuring easier access throughout the unit. This is especially important for seniors who may face mobility challenges in the future. Homes in Salmon Creek, WA and Camas, WA would benefit from such a design to enhance accessibility.
  • Wide Doorways and Hallways: Ensure doorways and hallways are at least 36 inches wide, though 40 inches or more is ideal. This allows for easy maneuvering of wheelchairs, walkers, and other mobility aids.
  • No-Step Entry: Incorporate a no-step entry with a gentle slope or ramp. This feature makes it easier for individuals with limited mobility to enter and exit the ADU safely, which is particularly beneficial in regions like Lake Oswego, OR and Happy Valley, OR.

Safety Features


Safety is a top priority when designing an ADU for aging parents. Consider these features to minimize the risk of accidents:

  • Non-Slip Flooring: Choose flooring materials with a high Dynamic Coefficient of Friction (DCOF) of 0.42 or greater. Non-slip surfaces help prevent slips and falls, which is crucial for maintaining safety in homes across Ridgefield, WA and West Linn, OR.
  • Adequate Lighting: Install bright, even lighting throughout the ADU. Motion-sensor lights in hallways and bathrooms ensure that spaces are well-lit even at night, improving visibility and safety.
  • Grab Bars: Strategically place grab bars in bathrooms, near the bed, and along hallways. These provide essential support and stability, reducing the risk of falls and injuries.

General Layout Considerations
An effective layout enhances both functionality and convenience.

  • Open Floor Plan: An open floor plan facilitates easier navigation with a wheelchair or walker, making the space more user-friendly and connected.
  • Easy Access to Bathroom Spaces: Position bathrooms in easily accessible locations. Ideally, bathrooms should be close to the bedroom to minimize the distance seniors need to travel, particularly during the night. This is especially relevant in Beaverton, OR and Tigard, OR.

Specific Features and Products for Senior-Friendly ADUs

Kitchen Design


The kitchen is a central part of any home and requires thoughtful design to ensure it meets the needs of aging parents.

  • Lowered Countertops: Include sections of countertops at lower heights for ease of use from a seated position. This adjustment is particularly beneficial for those who use wheelchairs.
  • Drawer Appliances: Install drawer microwaves and dishwashers at a lower height to minimize the need for reaching and bending. These appliances are safer and more ergonomic than traditional models.
  • Induction Cooktops: Consider using induction cooktops, which heat through electromagnetic induction, making the surface cooler and reducing the risk of burns or fires. This is a useful feature for homes in Clackamas, OR and Battleground, WA.

Bathroom Design


Bathrooms require special attention due to the high risk of falls.

  • Zero-Threshold Showers: Install zero-threshold showers to eliminate the need to step over barriers. These showers are easier to access with a wheelchair and reduce the risk of falls. Adding grab bars to these showers enhances safety further.
  • Shower Seats: Include built-in shower seats or ensure enough space to place a portable seat. This feature allows seniors to sit while showering, reducing fatigue and the risk of slipping.
  • Handheld Showerheads: Use handheld showerheads with adjustable heights for flexibility and ease of use, whether standing or sitting.

Additional Features


Incorporate features that enhance comfort and usability:

  • Grab Bars and Handrails: Install these throughout the ADU, especially in areas like the bathroom and along hallways.
  • Senior-Friendly Entrance: Design entrances with easy-to-use handles and good lighting to make access straightforward and secure.
  • Storage Solutions: Include ample storage solutions that are easy to reach and organize. This helps in maintaining an organized and clutter-free environment.

Conclusion

Designing an ADU for an aging parent involves careful consideration of accessibility, safety, and comfort. By incorporating features such as single-level designs, wide doorways, and non-slip flooring, you can create a space that supports their independence and meets their evolving needs. In areas like Washougal, WA and Hillsboro, OR, where ADU development is growing, these principles will help ensure that the final result is a safe, functional, and inviting home for your aging parents.
