ADUs, Shared Housing, and Family Property Planning
Multigenerational living is not a new idea. But it is having a significant resurgence — and for reasons that go beyond sentiment.
Housing costs across Colorado's Front Range have changed what many families consider financially realistic. At the same time, aging parents want more proximity to family, adult children are managing caregiving responsibilities alongside careers and their own households, and the traditional model of fully independent households for every generation is feeling increasingly strained for many families.
Multigenerational arrangements — done thoughtfully — can create real benefits: lower overall housing costs, stronger family support systems, reduced isolation, and better long-term flexibility as circumstances evolve.
Done without sufficient planning, they can create the opposite: privacy friction, financial complexity, and relationship strain that nobody anticipated.
The arrangement itself is rarely the deciding factor in success. The planning, expectations, and communication that surround it almost always are.
Accessory Dwelling Units have become one of the most discussed housing solutions in Colorado — and for good reason. In the right situation, they offer something genuinely valuable: proximity without full cohabitation.
An ADU can take several forms:
The most important factor in sustainable multigenerational living is not the size of the home — it is whether the space genuinely supports privacy and independence for everyone involved.
Many families assume that a larger house solves the problem. It often doesn't. A large home without thoughtful separation can feel more intrusive than a smaller one with well-designed independent zones.
Properties that already have these features — or can be practically modified to create them — make much stronger multigenerational candidates than those requiring extensive structural work to achieve separation.
Even families with excellent relationships can struggle when expectations around privacy, shared space, and daily routines are unclear or assumed rather than discussed.
The conversations that matter most tend to happen before anyone moves in — not after friction has already developed.
Which spaces are shared by arrangement, which are private by default, and what is the protocol for each?
What does dropping by look like? Is there a knock-first expectation? What about grandchildren?
What caregiving expectations exist — now and if needs increase? Who is responsible for what?
Who contributes what toward utilities, maintenance, shared costs? Is this formal or informal?
What happens if the arrangement stops working? If health needs escalate? If someone wants to move?
Multigenerational housing can create meaningful financial advantages — but it also creates complexity that families should understand before committing.
These are questions for estate attorneys, financial advisors, and CPAs — not just real estate advisors. The property decision and the legal/financial structure around it should be developed together, not sequentially.
