Beyond the Casita: A Real-World Guide to Finding a Multigenerational Home in the East Valley

I’ll never forget the conversation. I was sitting at a kitchen table in Gilbert with a couple I’d helped find their first home years ago. Now, they were wrestling with a new, beautiful challenge. Her mom, who lived out of state, needed more support. His recent college grad son was moving back home to save money. Their perfectly sized starter home suddenly felt impossibly small.

“We’ve been searching online for homes with a casita,” she told me, scrolling through listings on her phone with a tired look in her eyes. “But they’re either way out of our price range, or the casita is just… a box in the backyard. It doesn’t feel like a home.”

I nodded because I’ve heard this story so many times. The dream of multigenerational living is huge right now—and for good reason. It’s a return to a beautiful, practical way of life. But the online search for it is often frustrating and narrow. The truth is, the perfect multigenerational home is rarely found by just checking the “guest house” box on a real estate portal.

It’s about finding a home with the right bones and the right flow for your unique family. It’s about understanding the subtle differences between a true dual primary suite and a downstairs bedroom. And now, with Arizona’s new laws making it easier to build Accessory Dwelling Units (ADUs), it’s also about seeing the hidden potential in a property. Let’s go beyond the casita and talk about what a real-world search for a multigenerational home in the East Valley looks like.

Quick Answer Summary

What is the best way to find a multigenerational home in the East Valley?

Instead of limiting your search to homes with existing casitas, broaden your criteria to include properties with flexible layouts. Look for homes with dual primary suites (one up, one down), finished basements, separate bonus rooms with adjacent bathrooms, or large lots that are suitable for adding a new ADU (Accessory Dwelling Unit) under Arizona’s 2025 law.

What are the key features of a successful multigenerational home?

The best multigenerational homes balance connection with privacy. Key features include separate entrances, distinct living areas (even small ones), kitchenette or wet bar capabilities, and sound insulation between living spaces. The goal is to allow family members to live both together and independently under one roof.

Can I build a casita on any property in the East Valley?

Arizona’s new ADU law requires cities to permit the construction of casitas on most single-family lots, but local rules regarding size, placement, and utility connections still apply. It’s crucial to work with an agent who understands the specific zoning codes in cities like Gilbert, Chandler, and Mesa to identify properties with true ADU potential.

The Three Flavors of Multigenerational Homes

When we start looking for a multigenerational home, I encourage my clients to think in terms of three main categories. Each one offers a different level of privacy, cost, and flexibility.

1. The Integrated Suite (The “In-Law” Setup)

This is the most common and often most affordable option. It’s not a separate structure, but a dedicated space within the main house that functions as a private apartment.

•        What it looks like: Typically, this is a downstairs bedroom with an en-suite bathroom, often located near a separate entrance. The best versions also have an adjacent den or living space that can be used as a private sitting room. I once helped a family in Mesa find a home with a downstairs suite that had its own small living room and a wet bar—it was the perfect setup for their aging father, giving him a sense of independence while keeping him connected to the family.

•        Pros: More affordable, easier to find, and keeps everyone physically connected.

•        Cons: Less privacy, potential for noise transfer, and shared kitchen space.

2. The Dual-Living Home (Two Homes in One)

This is the holy grail for many families. These are homes specifically designed by the builder for multigenerational living, and they are becoming more common in newer East Valley communities.

•        What it looks like: These homes often feature a full “Next Gen” or “Extra Suite” apartment attached to the main house, complete with its own private entrance, living room, kitchenette, bedroom, and bathroom. Builders like Lennar and K. Hovnanian have been leaders in this space. The key difference here is the kitchenette and separate living room, which create a true sense of a separate home.

•        Pros: The perfect balance of privacy and connection. Designed for this purpose from the ground up.

•        Cons: Higher price point and limited to newer construction communities.

3. The Blank Canvas (The ADU Potential Property)

This is where the search gets really exciting and strategic. Thanks to Arizona’s new laws, we can now look at homes not just for what they are, but for what they could be. An ADU is a separate, detached dwelling on the same property, and finding a home with the right lot and zoning is like finding a hidden gem.

•        What it looks like: This could be a home on a larger lot (a quarter-acre or more) with a spacious, accessible backyard. We look for properties with no HOA or a lenient HOA, and we research the specific city zoning to confirm that a detached ADU is feasible. The home itself might be a standard single-family house, but the value is in the land and the potential it holds.

•        Pros: Ultimate privacy, potential for future rental income, and the ability to custom-design a space for your exact needs.

•        Cons: Requires a significant investment for construction, navigating city permits, and a longer timeline.

Beyond the Floor Plan: What Really Matters

Finding the right layout is only half the battle. A truly successful multigenerational home considers the human element—the day-to-day realities of living together.

•        Acoustic Privacy: When you’re touring a home, pay attention to sound. Are the walls between the main house and the suite well-insulated? Is the suite located under a high-traffic area like the kids’ playroom? Small things like solid-core doors can make a huge difference.

•        Separate Entrances: Even if it’s just a dedicated door to the backyard, a separate entrance provides a crucial sense of autonomy. It allows family members to come and go without feeling like they are intruding.

•        Outdoor Space: Think about how the outdoor space will be shared. Is there a separate patio for the suite? Can you create a private garden area? Shared outdoor space is wonderful, but having a small, private retreat is just as important.

A New Way of Living, A New Way of Searching

The rise of multigenerational living is one of the most positive trends I’ve seen in real estate. It’s a return to community, to family, and to a more sustainable way of life. But it requires a new way of thinking about the home search.

It’s about looking past the listing photos and seeing the potential in a floor plan. It’s about understanding the nuances of city zoning and the possibilities of a blank-canvas backyard. And most of all, it’s about having a clear vision for how your family wants to live—both together and apart.

If you’re on this journey, I’d be honored to help you navigate it. Let’s find a home that isn’t just a collection of rooms, but a place where every generation of your family can truly thrive.
