As our parents age, many of us face the emotional and practical challenge of ensuring they have safe, comfortable living arrangements. Whether they’re downsizing, needing extra support, or moving closer to family, planning suitable housing for elderly parents can be complex.

If you’re exploring options like building a granny flat or adding a minor dwelling to your property, here are five key considerations to help guide your decision.

1. Assess Current and Future Needs

Before choosing a housing option for your aging parents, take time to assess both their current lifestyle and anticipated future needs. Consider:

  • Accessibility – Will they need wheelchair-friendly access, wider doorways, or grab bars in the bathroom?

  • Health conditions – Do they have medical needs that may require more care over time?

  • Level of independence – Do they want to live independently in a self-contained unit, or will they need more hands-on support?

Planning ahead for the next 5–10 years can help future-proof your investment and avoid unnecessary relocations down the track.

2. Explore Housing Options for Elderly Parents

Once you’ve assessed their needs, it’s time to consider the best type of housing. Some of the most popular options for families in New Zealand include:

  • Renovating your existing home – This might mean adding a separate entrance, modifying a bathroom, or creating a self-contained area.

  • Building a granny flat or minor dwelling – These custom-built units can be installed on your property, providing privacy while keeping your loved ones close.

  • Aged care or retirement villages – Ideal for those needing full-time care or medical supervision.

  • Multi-generational living – Some families opt for shared housing designs that accommodate different generations under one roof.

A minor dwelling can be a great middle ground—providing independence, comfort, and the ability to remain on family land.

3. Understand the Financial and Legal Implications

Adding a granny flat for your parents isn’t just a personal decision—it’s also a financial one. Here are a few steps to take:

  • Set a clear budget – Factor in the cost of the build, site preparation, and any required consents or inspections.

  • Check for government support – There may be financial assistance or grants available for home modifications or senior care.

  • Review legal matters – Clarify ownership, property boundaries, and legal arrangements, especially if you’re sharing costs with family members.

Speaking with a financial advisor or elder care consultant can help you get everything in place before building begins.

4. Involve the Whole Family

Housing elderly parents is a major decision that can affect siblings, children, and extended family. It’s important to:

Multigenerational family having a relaxed conversation over coffee in a living room, discussing housing options for aging parents, including building a granny flat on their property.
  • Discuss financial and caregiving responsibilities openly.

  • Include your parents in the planning process and respect their preferences.

  • Communicate clearly to avoid misunderstandings and reduce family stress.

Approaching the situation as a team can help everyone feel supported and aligned.
