In 2021, large urban counties across the United States experienced a net loss of 863,000 residents — the first time in 50 years that big urban counties as a whole shrank. Sixty-eight percent of large urban counties lost population that year, an exceptionally high share by historical standards. Where did those people go? The majority moved to suburbs and exurban communities on the outer edges of metro areas, transforming what were once sleepy commuter towns into booming residential hubs. For home builders and developers, this shift represents one of the most significant urban infrastructure planning challenges and opportunities in a generation: learning how to build suburban communities that actually appeal to a generation raised on walkable city neighborhoods.
The Scale of the Urban-to-Suburban Population Shift
The data confirms that this is not a short-term pandemic anomaly but a sustained demographic realignment. According to the Economic Innovation Group, over 80% of exurban counties gained population in 2021, and the fastest-growing U.S. counties that year were predominantly suburban or exurban. The National Association of Realtors surveyed homebuyers and found that 41% of city dwellers who moved chose suburbs, while another substantial share moved even farther out to small towns and rural areas.
Equally telling: 72% of people who already lived in suburbs stayed in a suburban area, simply shifting to a different suburb. This indicates a strong and deepening preference for suburban living among movers. As big-city rents go up, that seems to be a significant motivation behind many pandemic moves: people hunting for more space at a price they can afford, said Riordan Frost, a housing researcher at Harvard. Affordability and space were top of mind, with buyers citing the need for outdoor space, bigger square footage, and quiet neighborhoods as key factors in choosing a new home.
Which Metropolitan Areas Are Seeing the Largest Shifts
Not all suburbs are growing equally. The data reveals clear patterns in which metro areas are experiencing the most dramatic population redistribution:
- Sun Belt metros — cities like Austin, Nashville, Charlotte, and Phoenix saw the strongest suburban and exurban growth, driven by lower home prices and warmer climates.
- Mid-sized cities — metros with 500,000 to 2 million residents captured a disproportionate share of millennial movers compared to the largest coastal cities.
- Secondary suburbs — the second and third rings of suburbs, sometimes 30 to 50 miles from city centers, grew faster than inner-ring suburbs in most regions.
- Mountain West and Southeast — counties in Colorado, Utah, Tennessee, and the Carolinas saw suburban growth rates two to three times the national average.
New suburban developments must account for the fact that many of these buyers are arriving from dense urban environments with expectations shaped by city living. They want space, but they do not want to sacrifice all the amenities they enjoyed in the city.
How Remote Work Rewrote Commuter Geography
For the first time, remote work allowed many people across the country to see a life in which the location of their job and where they live did not have to be one and the same, observed Adam Ozimek, chief economist at Upwork. Untethered from daily commutes, white-collar workers suddenly could consider homes far outside the traditional 30-minute commute radius. Luke Rogers, a demographer with the Census Bureau, noted that with many more people in working ages now able to work from home at least some of the time, it is likely that some people are more willing to live farther away from their place of employment than they would have in the past.
This newfound flexibility opened up housing options that were previously off the table. The same budget that bought a 700-square-foot apartment in a city center could now secure a 1,800-square-foot house with a yard in a suburban or exurban community. The trade-off — a longer commute on the days when office attendance is required — became acceptable when it meant commuting two or three days per week instead of five.
The Home Office as a Non-Negotiable Feature
Surveys conducted by the National Association of Home Builders show that a dedicated home office is now among the top five desired features for new home buyers, ranking above upgraded kitchens in some demographic segments. The most expensive cities for construction also tend to be the ones where remote work fueled the highest out-migration, suggesting that builders in high-cost metros face the dual challenge of expensive building conditions and a shrinking local buyer pool.
What a Proper Home Office Requires
Builders should consider the following specifications for home office spaces in new suburban homes:
| Feature | Minimum Standard | Premium Option |
|---|---|---|
| Room size | 10×10 ft | 12×14 ft with separate entrance |
| Network connectivity | Hardwired Ethernet + mesh WiFi | Fiber-ready conduit + dedicated UPS |
| Natural light | One window, north-facing | Two windows, operable, with blackout shades |
| Sound isolation | Insulated interior walls | Staggered studs + acoustic sealant |
| Power outlets | 4 outlets on separate circuit | 6 outlets + USB-C + data ports |
| Door type | Solid-core interior door | Solid-core with weatherstripping |
What Millennials Actually Want in a Suburban Home
The millennial generation, now in their prime home-buying years (ages 28 to 43 as of 2025), carries different expectations into the housing market than previous generations did at the same age. Many spent their twenties and early thirties renting apartments in walkable urban neighborhoods. They are not looking for the isolated, car-dependent suburban developments of the 1990s. They want what urban planners call suburban urbanism — the density, walkability, and mix of uses found in city neighborhoods, but packaged in a lower-density, greener, more family-oriented setting.
A significant proportion of millennial homebuyers are adult millennials still living at home, either because they cannot afford urban rents or because they are saving for a down payment. For home builders, this population represents pent-up demand that could unlock as suburban inventory grows. The key is building the right product at the right price point.
Priorities Ranked: What Millennial Buyers Value Most
- Affordability — Monthly payments at or below 30% of household income, which currently means homes priced between $250,000 and $450,000 in most markets.
- Outdoor space — A private yard, patio, or balcony large enough for dining and gardening.
- Home office — At least one dedicated room that can function as a remote work space.
- Walkability — Sidewalks, nearby parks, and access to coffee shops, restaurants, and grocery stores within a 15-minute walk.
- Energy efficiency — Lower utility bills through better insulation, efficient HVAC systems, and solar-ready infrastructure.
- Community amenities — Shared green spaces, community gardens, dog parks, and walking trails.
Building for Density Without Losing Suburban Appeal
The challenge for home builders is that many suburban zoning codes still favor large-lot, single-family developments that produce exactly the kind of low-density sprawl millennials say they want to avoid. To capture this market, builders need to work within existing zoning frameworks while pushing for density-friendly reforms. The mid-range solution that has gained traction is the missing middle housing types: duplexes, triplexes, townhouses, cottage clusters, and small-lot single-family homes.
The most walkable cities in the US share design patterns that builders can adapt for suburban contexts: narrower streets, connected sidewalk networks, mixed-use zoning that places retail within walking distance of homes, and higher intersection density that makes walking feel natural rather than circuitous. These are not big-city features — they are planning principles that work equally well in suburban town centers.
Suburban Density Models That Work
| Housing Type | Density (units/acre) | Lot Size | Typical Buyer |
|---|---|---|---|
| Cottage cluster | 8-12 | 1,500-2,500 sq ft | Singles, couples, empty nesters |
| Townhouse | 12-18 | 1,800-2,500 sq ft | Young families, professionals |
| Small-lot single-family | 4-7 | 3,000-5,000 sq ft | Families seeking yard space |
| Duplex/triplex | 10-20 | 2,000-4,000 sq ft building | Multi-generational households |
| Courtyard apartments | 15-25 | 600-1,200 sq ft per unit | Renters, first-time buyers |
Design Principles for Millennial-Oriented Subdivisions
- Front porches rather than front-loaded garages — creates social connection to the street.
- Alley-loaded garages — reduces visual dominance of cars and allows narrower lots.
- Connected sidewalk networks — every home should have a safe walking route to a park or common area.
- Community gardens and shared green spaces — compensate for smaller private lots.
- Mixed-use nodes — a coffee shop, daycare, or small grocery within walking distance adds enormous perceived value.
Infrastructure and Amenities That Support Suburban Growth
As suburbs grow, the infrastructure that supports them must keep pace. Roads, water systems, schools, and public transit all face increased demand. The walkable cities report 2025 highlights that suburban municipalities are increasingly adopting complete streets policies and multimodal transportation planning to serve growing populations. Builders who collaborate with local planners on infrastructure improvements can create communities that retain their value and appeal over the long term.
New suburban development also offers an opportunity to incorporate sustainable building practices from the ground up. Materials like smog-eating concrete, solar-ready roofing, and high-performance windows reduce long-term operating costs for homeowners and differentiate new subdivisions from older housing stock. Buyers in their late twenties and early thirties consistently rank energy efficiency and lower utility costs among their top decision factors, and homes that deliver on these metrics command price premiums of 3% to 5% over comparable standard-construction homes.
The top cities for first-time homebuyers share common market factors that builders should study: job growth above the national average, median home prices below 3.5 times median household income, and a pipeline of new construction that keeps inventory moving. Suburbs within commuting distance of these cities are well-positioned for the next wave of millennial home buying.
For builders willing to rethink lot sizes, street design, and amenity packages, the suburban boom represents a generational opportunity. The millennials leaving cities are not abandoning urban values — they are looking for a version of city life that fits the next stage of their lives. Suburbs that deliver walkability, affordability, and thoughtful design will capture this market for years to come.
