ADUs for Multigenerational Living: Keeping Your Family Close

Flor Costilla ·

The Return of Multigenerational Living

For centuries, families lived together. Multiple generations under one roof (or on one property) was the norm, not the exception. In recent decades, that tradition faded — but now it's making a powerful comeback, driven by rising housing costs, an aging population, and the simple desire to keep family close.

ADUs are at the heart of this movement.

Why Families Are Choosing ADU Living

For Aging Parents

  • Independent living with family nearby for support
  • No nursing home costs ($5,500+/month savings vs. assisted living)
  • Grandparents can be part of grandchildren's daily lives
  • Medical emergencies are seconds away, not miles

For Adult Children

  • A launchpad while saving for their own home
  • Privacy and independence while staying connected
  • Eliminated rent payments accelerate savings
  • Especially valuable in expensive SoCal housing market

For Caregivers

  • Live-in caregiver housing without sacrificing your home's privacy
  • Professional caregivers value the independence of a separate unit
  • Easier to attract and retain quality caregivers

Design Considerations for Family ADUs

When designing an ADU for family members (vs. rental tenants), priorities shift:

For Aging Parents:

  • Single-story design (no stairs)
  • Walk-in shower with grab bars and bench
  • Wide doorways (36" minimum) for wheelchair accessibility
  • Lever-style door handles (easier than round knobs)
  • Good lighting throughout
  • Emergency pull cords or smart home monitoring
  • Connected pathway to main house (covered walkway)

For Adult Children:

  • Separate entrance for privacy
  • Full kitchen for independence
  • In-unit laundry
  • Dedicated workspace/office area
  • Interior door connecting to main house (optional, for convenience)

The Financial Advantage

Building an ADU for a family member isn't just emotionally rewarding — it's financially smart:

  • Avoid assisted living costs: Save $66,000+/year vs. assisted living
  • Build equity: The ADU increases your property value by $100,000–$175,000
  • Future flexibility: When family circumstances change, the ADU becomes a rental generating $2,000–$3,000/month
  • Tax benefits: Consult your CPA about potential property tax and construction deductions
