Next Gen Homes in Dallas–Fort Worth: The Complete Guide to "A Home Within a Home"

Who builds them, who they're perfect for, and how to find pre-owned Next Gen homes on the resale market in DFW.

One of the fastest-growing requests I get from North Texas buyers is some version of the same question: "Is there a home where my mom can live with us but still have her own space?" or "Can we buy something my college kid can move into without us all living on top of each other?"

The answer is yes — and the category has a name. Next Gen homes (short for "next generation") are single-family homes with a private, self-contained suite built right in: essentially an apartment within a house. They've quietly become one of the most practical, financially smart housing options in Dallas–Fort Worth, and this guide covers everything — what they are, which builders build them, and the part most articles skip: how to actually find a pre-owned one.

What Exactly Is a Next Gen Home?

Picture a normal, great-looking suburban home from the street. Now picture that tucked inside it — under the same roof, within the total square footage — is a fully private mini-apartment. That's a Next Gen home.

A true Next Gen suite typically includes:

A private bedroom
A full private bathroom
A living area / sitting room
A kitchenette (sink, counter space, often a fridge and microwave; sometimes a full small kitchen)
A walk-in closet
Its own separate exterior entrance — so the occupant can come and go independently
An interior door connecting to the main house — so it can be fully joined or fully private
Sometimes its own dedicated one-car garage and, in some plans, separate laundry

The private suite usually runs somewhere around 500–700 square feet — a genuine living space, not a converted bedroom. The magic is in that dual-door design: open the interior door and it's one big connected home; close it and lock the exterior door, and the suite lives like its own private residence with total independence.

A quick naming note: "Next Gen®" and "The Home Within a Home®" are actually Lennar's trademarked brand names. Other builders offer the same concept under different labels — "guest suite," "casita," "multigen suite," "dual-living," or "in-law suite." So when you're shopping, you're really hunting for the feature, not just the brand name. (This matters a lot for resale searches — more on that below.)

Who Are Next Gen Homes Great For?

The beauty of these homes is their flexibility. The same floor plan can solve completely different life situations — and can change roles over the years as your family's needs change.

1. An aging parent or family member. This is the original and most common use. Instead of moving Mom or Dad into a spare bedroom (or paying for assisted living), they get their own upscale, private suite — close enough that you know they're safe and not alone, private enough that everyone keeps their independence and dignity. Grandkids get more time with grandparents; you get peace of mind; nobody feels like they've lost their space.

2. A college kid or "boomerang" young adult. Kids come home from college, or launch into their first job before they can afford their own place. A Next Gen suite gives a 20-something real independence — their own entrance, their own space — while they save money, without the friction of everyone sharing one household's common areas.

3. Rental income (when the rules allow it). Some owners use the suite to generate income by renting it out — but this comes with important conditions around HOA rules, deed restrictions, and city ordinances. Done right it can help offset your mortgage; done without checking the rules, it can create real problems. I've dedicated a whole section to this below because it's where buyers most often get tripped up.

4. Long-term guests and visiting family. Out-of-town relatives, adult siblings, or friends who stay for extended visits get comfortable, private accommodations — and you get your guest room (and your sanity) back.

5. A home office, studio, or flex space. Not everyone needs it for people. That private suite with a separate entrance makes an outstanding home office for a client-facing business, a creative studio, or a quiet work-from-home wing that's fully separated from family life.

Which Builders Build Next Gen Homes in DFW?

Several of the biggest names in North Texas homebuilding offer some version of the multigenerational suite. Here's who to look at and how they differ.

Lennar — Next Gen® "The Home Within a Home" (the category leader)

Lennar was the first major national builder to productize this concept, and it remains the most established and purpose-built option in DFW. Their Next Gen® suites are designed from the ground up as integrated private living quarters — separate entrance, kitchenette, living room, bedroom, and bathroom, with some plans adding a private one-car garage. Lennar offers Next Gen in a wide swath of DFW master-planned communities (they've historically marketed multiple Next Gen floor plans across many North Texas municipalities), including growth areas like Princeton and other suburbs. Because Lennar builds so many of them, they're also the homes you'll most often find on the resale market.

Highland Homes — guest suites & casita options

Highland, one of Texas's most respected builders, offers select floor plans with dedicated guest suites or casita options in various DFW communities (including areas around Frisco, Prosper, and other Collin County developments). Great for buyers who want a premium move-up builder with a multigen layout.

Perry Homes — attached suites & detached casitas

Perry offers plans with attached guest suites or detached casitas in select DFW communities — a good option if you want the private quarters to feel a bit more separated from the main home.

Taylor Morrison — multigenerational guest suites

Taylor Morrison offers multigenerational "guest suite" configurations — a separate living space, bedroom, and bathroom — plus some flex layouts that can be adapted for multigen use.

Custom builders — the premium, fully-separate option

For the ultimate in privacy and independence, DFW custom builders can design a home with completely separate quarters — separate HVAC, separate full kitchen, separate entrance, sometimes a true second dwelling on a larger lot. This is the top of the market (budget roughly $600K–$1.2M+), but it delivers maximum autonomy for every generation.

The key takeaway: only Lennar can call it "Next Gen®," but multiple builders build the same idea. Shop the feature, compare layouts, and — critically — make sure it's a real, purpose-built suite, not a bedroom a builder simply relabeled. The difference shows up fast in daily life and at resale.

How to Find PRE-OWNED (Resale) Next Gen Homes in DFW

Here's where most buyers get stuck. New Next Gen homes are easy to find on builder websites — but pre-owned ones are scattered across the general resale market and can be genuinely hard to surface, because they don't have their own tidy category on the big home-search portals. Here's how to actually find them.

1. Search the right keywords

Resale Next Gen homes get described in the listing remarks using a whole range of terms. When you (or your agent) search the MLS, Zillow, Realtor.com, Redfin, or Homes.com, look for:

"Next Gen" / "NextGen"
"home within a home"
"two homes under one roof" / "dual living"
"guest suite" / "guest quarters"
"casita"
"mother-in-law suite" / "in-law suite"
"second kitchen" / "kitchenette"
"separate entrance" / "private entrance"
"multigen" / "multigenerational"

2. Work with an agent who can run a real MLS search

This is the big one. The public portals bury or omit the exact fields that identify these homes. The MLS lets an agent filter by feature and keyword in ways the consumer apps can't — searching listing remarks, "guest quarters" fields, second-kitchen flags, and more. This is the single most effective way to find resale Next Gen homes, and it's exactly the kind of targeted search I set up for clients. (It's also free to you — see the note at the end.)

3. Target the communities where they were built

Resale Next Gen homes cluster where builders originally sold a lot of them. If Lennar built Next Gen floor plans in a given master-planned community, that's where the resales will eventually appear. Knowing the DFW communities with a high concentration of original Next Gen construction lets us watch those neighborhoods specifically for listings.

4. Set up instant alerts

Because true resale Next Gen homes are relatively scarce and tend to sell to motivated multigen buyers, speed matters. An automated alert the moment a matching listing hits the MLS is often the difference between touring it and missing it.

5. Vet the suite carefully before you buy

Not every "guest suite" resale is created equal. Before you commit, confirm:

The suite is legally permitted and was built (or converted) with proper permits
It has the features you actually need (a real kitchenette, private entrance, etc.) — not a relabeled bonus room
The home appraises with the suite's value supported by comparable sales
If you want rental income, the HOA/deed/city rules actually allow it (next section)

The Financial Case for Next Gen Living

Beyond the emotional benefits, the numbers are a big reason multigenerational living has become "part of the DFW housing identity," as one Texas A&M Real Estate Research Center economist put it. Industry estimates of the potential savings from combining households include:

Housing costs: roughly $1,500–$2,100/month saved by consolidating two households into one
Childcare: roughly $1,200–$2,500/month per child when a live-in grandparent helps
Eldercare: roughly $30,000–$50,000/year versus independent living with full-time care

Combined, families often cite $50,000–$100,000+ per year in potential savings. (These are general estimates, not guarantees — your situation will vary.)

There's also a financing advantage: multiple family members can co-borrow on the same mortgage, combining incomes to qualify for a stronger loan. FHA and conventional programs allow non-occupant or co-borrower arrangements under certain conditions — a real help when two generations are buying together. (I'm not a lender, so let's connect you with a good one to run your specific scenario.)

The Rental-Income Reality Check (Read This Before You Count on It)

Renting out the Next Gen suite is one of the most attractive ideas buyers bring to me — and also the one with the most fine print. Here's the honest picture for Texas:

There's no single statewide rulebook. Texas leaves these decisions largely to local municipalities, so what's allowed in one city may be prohibited a few miles away. Rules on whether a suite can be rented separately, occupancy limits, and permitting all vary by city.
Some cities restrict the suite to family use or don't permit it to be rented as a separate dwelling at all. A Next Gen suite is typically part of the single-family home (not a separately metered legal ADU), which affects how — and whether — it can be leased.
HOA rules and deed restrictions are a separate layer from city rules, and they operate independently. Many DFW subdivisions have leasing restrictions or outright limits in their CC&Rs. In Texas, an HOA can enforce leasing limits if they're spelled out in the governing documents — so those documents are exactly what you need to read.
Short-term rentals (Airbnb/VRBO) face extra scrutiny. Many HOAs restrict or ban short-term rentals entirely, and those rules can carry legal weight.

The bottom line on rental income: it can be a real benefit in the right community — but never assume it. Before you buy a home planning to rent the suite, we pull the HOA governing documents and deed restrictions and check the city's ordinances for that specific address. This isn't legal advice — for anything complex, a real estate attorney is worth the small cost — but it's the homework that keeps a smart plan from becoming an expensive mistake.

The Bottom Line

Next Gen homes solve a very real, very modern problem: how to keep family close without giving up privacy, independence, or financial sanity. In Dallas–Fort Worth, you've got strong options — Lennar leads the purpose-built category, with Highland, Perry, Taylor Morrison, and custom builders all offering their own take.

Buying new is straightforward. Finding a great pre-owned Next Gen home is where having the right agent and the right search strategy makes all the difference — and it's exactly the kind of hunt I love.
