ADU Solutions for Aging in Place in Claremont

Comfort is essential for many older adults in California who prefer the familiarity and independence of remaining in their own homes and communities over moving to senior living facilities. The main challenge lies in finding a way to maintain this comfort without extra monthly costs while ensuring they have the necessary support and possibly increasing the property’s value. This article outlines a practical approach to achieving this goal.

Adding an ADU, a close living space on your property, is a useful way to create additional room. This option offers an affordable way for older adults to live near family while still maintaining their independence. If circumstances shift in the future, the space can be conveniently repurposed for other needs.

Understanding ADUs and their Benefits for Aging in Place in Claremont

What is an ADU?

An ADU, or Accessory Dwelling Unit, is a small living space on the same property as a main house or apartment. Known as granny flats or in-law suites, ADUs should be equipped with permanent facilities for living, sleeping, cooking, eating, and sanitation. They can be added as attached, detached, or by converting an existing space.

Benefits of ADUs for Aging in Place

Close to Family: ADUs allow older adults to live nearby while keeping their own space and independence, with family close by for assistance.

Affordable Alternative: ADUs can be a budget-friendly alternative to retirement communities, helping families stay close without high costs.

Easy-to-Use Features: ADUs can be set up with wider doorways, one-story layouts, and slip-resistant floors to support seniors who may have mobility concerns.

Flexible for Future Use: If a senior doesn’t need the ADU, it can be adapted for other uses, like renting it out or providing living space for other family members.

How to improve the property to fit your elderly parent?

When preparing a living space for an elderly parent, especially one dealing with memory concerns, it’s essential to create an environment that feels comfortable, safe, and easy to navigate. Simple adjustments, such as labeling items or organizing furniture, can help them move around more confidently and with less confusion.

A one-story ADU with a basic layout—featuring a bedroom, bathroom, and a cozy seating area—works well. Ensuring good lighting, adding handrails, and using furniture with smooth, rounded corners can reduce the risk of accidents. In the kitchen, open shelving or see-through cabinets make it simpler to locate items.

For added safety, smart features like motion-activated lighting or alert systems can notify you if something seems off, allowing your parent to maintain their independence while providing you with reassurance that they’re safe and close by.

What are the economics of building an ADU for the aging-in-place scenario?

Many older couples have already paid off their mortgages, which can work in your favor. If this is your situation, you could consider a Home Equity Line of Credit (HELOC) to cover ADU construction costs. Once the ADU is finished and your parents or relatives move in, you could rent out the main house to help pay back the HELOC. The key factor is ensuring the rental income from the main house is enough to cover the HELOC payments. Although it may seem complex, using a simple example can help you see how the numbers might work.

Let's consider that your parents would be happy to live in a 2 bedroom with 2 bath ADU. The size for such an ADU is approx. 1,200 sq. ft. The cost of a 1,200 sq. ft. ADU in Claremont is $520,632. A loan that has a 6.5% interest rate, requires a monthly payment of $3,291. Ideally, you could rent the main house with at least the same amount as your payments for the HELOC. This way you'll break even on your monthly expenses, while you're having someone keeping an eye on your parents and increasing the value of this property.

Besides providing the right living spaces for your parents at potentially break-even costs per month, this ADU could add around $600,000 to the property’s market value if you decide to sell.
