When Retirement Plans Change: How Adult Children Living at Home Affects Your Estate Planning Strategy

For California residents navigating the evolving landscape of multi-generational living and estate planning

Is Your Retirement Plan Accounting for Adult Children at Home?

If you’re a California resident preparing for retirement or already retired, you may be facing a reality your parents never anticipated: adult children who need to move back home—or who never left in the first place. This growing trend is fundamentally changing how families approach estate planning, asset transfers, and retirement financial strategies.

According to a 2025 Fidelity Investments report, 17% of Canadian retirees have allowed non-student adult children to live with them for free or at reduced rent during retirement. While this data comes from Canada, California families are experiencing similar pressures due to high housing costs, challenging job markets, and increased living expenses.

Why This Matters for Your Estate Plan

Traditional retirement planning assumes you’ll downsize your family home, convert the equity into retirement income or investments, and enjoy travel and leisure during your “golden years.” But what happens when your adult children need housing support?

Real-world scenarios affecting California families:

  • Delayed home sales: You planned to sell your family home and move to a smaller property, but your adult child needs affordable housing in California’s expensive market
  • Modified financial projections: Your retirement income must now cover higher household expenses—utilities, groceries, insurance, and property taxes—for a larger household
  • Changed inheritance strategies: Instead of selling the family home, you’re now considering leaving it to your child who cannot afford a down payment in California’s housing market
  • Reduced retirement lifestyle: Supporting adult children often means cutting back on travel plans, postponing major purchases, or eliminating lifestyle expenses like fitness classes or hobbies
  • What Financial Experts Say About This Shift

    Shannon Lee Simmons, a financial planner and founder of the New School of Finance, notes that this trend is impacting retirees during “the first 10 years of their retirement. Those are the ones where you’re, quote, supposed to travel while you’re young and healthy.”

    The key insight: “This is done out of love, not frustration. But people are expecting to have the most amount of freedom and flexibility in doing all the things, and there’s an adjustment of expectations.”

    How Can I Adjust My Estate Plan for Multi-Generational Living?

    If you’re a California resident facing this reality, consider these strategic planning adjustments:

    1. Reassess Your Timeline for Downsizing

  • Generation X clients are now planning for children to remain at home until age 30, compared to the traditional expectation of early 20s
  • Build flexibility into your retirement plan that accounts for extended co-habitation
  • Consider whether your current home can accommodate multi-generational living long-term
  • 2. Establish Clear Financial Arrangements

    Financial planners recommend addressing the rent question directly. Leslie Logan, senior financial planner with TD Wealth, suggests charging rent can offset higher household costs like groceries and utilities. Consider:

  • Setting a fair monthly rent amount that helps cover increased expenses
  • Creating a graduated rent structure (e.g., starting at $500/month and increasing annually)
  • Using rent payments to fund specific retirement goals, such as a travel fund
  • Documenting all financial arrangements in writing to protect both parties
  • 3. Revise Your Estate Transfer Strategy

    If your adult child cannot afford California’s housing market, you may need to reconsider how you transfer the family home:

  • Evaluate whether gifting the home through your estate makes more financial sense than selling
  • Understand the California property tax implications of transferring real estate to children
  • Consider establishing a trust that allows your child to remain in the home while protecting the asset
  • Review Proposition 19 rules if you’re transferring a primary residence to your children
  • 4. Update Your Mortgage and Financial Timelines

    Some California families are adjusting their mortgage strategies:

  • Accelerating mortgage repayment to afford staying in the family home longer into retirement
  • Extending payment timelines and planning to retire later, expecting children will still be home
  • If you have a basement apartment or ADU, modeling the loss of rental income if your child occupies that space
  • Real California Families Making This Work

    While the examples in the source article come from Canada, the same principles apply to California residents facing similar challenges. One family established a clear agreement: adult children could live rent-free until age 25 while working or attending school, then pay $500 monthly rent, increasing $100 each year. This structure gave their children time to save for down payments while ensuring the parents’ expenses were covered.

    Another retiree chose to delay selling the family home after their son needed affordable housing, adjusting their retirement plans to accommodate this new reality while planning to leave the property to him in their estate since he couldn’t afford a down payment.

    The Cultural Shift: Family Support as Retirement Strategy

    Victor Couture, an associate professor at the University of Toronto’s Rotman School of Management, suggests this may reflect “a shifting attitude in North America toward relying more heavily on family in difficult times.”In European countries like Spain, multi-generational living helped families survive extended periods of high unemployment.

    As one California-area resident preparing for retirement observed: “The thinking I was taught was, ‘they should be out on their own.’ Now I really get it in a way I didn’t get it before. Supporting them is so important.”
