A Growing Community

O’Fallon has the highest suburban population in the St. Louis Metro area, with 96,101 people as of July 2025, up from 91,316 in the 2020 census, according to the U.S. Census Bureau. St. Charles County as a whole is at 426,499.

O’Fallon’s growth has played a big role in earning it a reputation as one of the region’s most thriving communities.

It’s one of the fastest-growing cities around St. Louis.

We’ve had the privilege of working with so many people who have moved to O’Fallon from all over the country!

While some suburbs may cover more ground, like Wildwood (the largest in STL County) with its expansive 68.89 square miles, O’Fallon makes the most of its 29.78 square miles.

Rankings That Are Hard To Beat

• #6 on SafeWise’s Missouri’s Safest Cities (2026), up seven places

Why O’Fallon Stands Out

O’Fallon is easy to get to and affordable.

Plus, residents express a sense of safety.

No wonder so many people are choosing to call it home.

Cost of Living

Housing is usually the biggest expense for most people, and it is where O’Fallon saves you the most. Redfin puts the city’s overall cost of living about 4% below the national average (2026), and housing is the line that carries it.

O’Fallon residents also benefit from lower everyday costs.

Energy expenses are 9.5% below the national average, transportation is 11.7% less, and healthcare costs are 6.7% lower.

Safety

O’Fallon ranks #6 on SafeWise’s Missouri’s Safest Cities list for 2026, up seven places on the year, with a reported violent crime rate of 0.5 per 1,000 residents and a property crime rate of 4.8 per 1,000. Both fell from the previous year (0.7 and 7.2).

According to the city’s website, this is due to a low crime rate and community initiatives with goals to make O’Fallon one of America’s safest cities.

Community

There’s a sense of community pride when it comes to living in O’Fallon.

It’s hard to be bored here.

This vibrant community has year-round events like Shakespeare in the Park, the concert series at the O’Day Amphitheater, and the Fine Arts Fair in the Fall.

What Do Residents Have To Say?

O’Fallon residents consider it a good place for young families with a strong sense of community and family values.

Here are some quotes from real O’Fallon residents!

• “I’ve lived in O’Fallon my whole life; it’s a great community.”
• “If you like nature, there are a ton of awesome parks around.”
• “ [O’Fallon is] one of the fastest-growing parts of the metro, so there’s lots of new and good restaurants out here.”

O’Fallon offers affordability, safety, a strong sense of community, and easy access to nearby attractions.

Plus, there’s plenty to do right in town!

It’s no surprise people are moving here in droves.

Neighborhoods in O’Fallon

O’Fallon has a little bit of everything when it comes to housing.

If you’re a suburbanite, you’ll love it here.

It has everything from established ranch-style homes to new single-family homes to villas and condos.

In August 2026 the median sale price for all home types was somewhere between the mid $370,000s and about $400,000, depending on which aggregator you ask (Redfin, Realtor.com and Zillow disagree by about $25,000 in the same month), and homes were going under contract in a week or two.

Whether you’re looking for an older home with charm or a brand-new home, O’Fallon has options.

You can see every O’Fallon home for sale before you pick a neighborhood.

Let’s dive in and look at some of the neighborhoods and developments around town!

Established Areas

Northern O’Fallon

According to Nextdoor, North O’Fallon is the friendliest neighborhood in O’Fallon!

It’s made up of a few different subdivisions, and most of the houses were built between 1985 and 2001.

This affordable area has small to medium single-family homes with price ranges in the low $200s to mid $300s.

Highway P and Main

This neighborhood is located in northern O’Fallon, with Main Street and North Main Street providing easy access to restaurants and businesses.

It features a diverse mix of architectural styles, including ranch, two-story, and split-level homes, with some showcasing brick exteriors, others with siding, and even a few boasting in-ground pools.

The homes here also tend to sit on larger, grassy lots, offering plenty of outdoor space.

Prices in this area range from the low $200s to the upper $300s, depending on what section you’re in, with a few of the larger homes getting up to the $400s.

Great Warrior Drive

Most homes in this neighborhood were built between 1986 and 1988 and are primarily ranch-style, with prices typically ranging from the mid to upper $200s.

Residents love the area’s convenience, thanks to its proximity to Fort Zumwalt West High School and the businesses along Bryan Road, which forms the neighborhood’s eastern boundary.

Parkview

This neighborhood is perfect for those who love green spaces, with Fort Zumwalt Park to the south and east, providing easy access to its many amenities.

Most homes here are ranch-style with attached garages, and prices range from the upper $200s to mid-$300s for small to medium-sized homes, while larger homes can reach the $500s.

Many homes were built in the late 1990s, offering a mix of modern convenience and established charm.

Other Established Neighborhoods in O’Fallon include The Crossings, Deer Creek, and Patriots Landing. Most of these neighborhoods feature ranch-style homes, sidewalks, and green spaces.

The City of O’Fallon started building out in the mid-1980s with a population boom in 1999, which meant more housing and infrastructure.

Acreage and Estate Properties

O’Fallon is not all subdivisions. The rural edges of town still have farmhouses on acreage and a handful of true estates, and they come up for sale less often than the neighborhoods above.

The one in this video is by no means the average O’Fallon property: a 15-acre compound with a main house, a guest house, a pool, and two outbuildings, listed at $2.9 million in September 2026. It shows what you can buy here if you want acreage, room for more than one generation under one roof, or space to run more than one business from home.

New Developments in O’Fallon

O’Fallon has many new developments in the works, mostly on the western edge of town.

Here are some highlights of new residential developments in the area.

Streets of Caledonia

16:2016 minutes, 20 seconds

Living St. Louis

This development, in progress by Fischer Homes and Lombardo Homes, offers dozens of floor plans, ranging from townhomes to spacious single-family homes. Phases 3 and 4 were under construction in September 2026, and a 112-room Cambria Hotel on Rush Way is scheduled to open in spring 2027.

This strategic location provides quick access to I-64 and is surrounded by shopping and dining options.

Plus, Caledonia is directly across the highway from Mastercard’s Operations headquarters.

Situated in southwest O’Fallon, it’s just a stone’s throw from Dardenne Prairie and Lake St. Louis, making it a convenient and desirable place to call home.

Fun fact: Our real estate team’s office is in the Streets of Caledonia at 950 Caledonia Drive.

One of our favorite group activities is grabbing Mexican food at Casa Tequila right next door.

Sommerlin by McKelvey Homes

Just west of the Streets of Caledonia, you’ll find Sommerlin by McKelvey Homes. It is essentially finished: McKelvey was down to its last two homes when we checked in September 2026, so this is now a resale neighborhood rather than a place to pick a lot.

This community offers a mix of single-story ranch and two-story homes.

Like Caledonia, Sommerlin boasts a convenient location with easy access to shopping, dining, and major roads, but with the added perk of being just a mile south of Liberty High School.

Harvest at Hopewell

Harvest is a massive new development in unincorporated O’Fallon.

21:2121 minutes, 21 seconds

Living St. Louis

Almost 900 homes will be built. McBride is the lead builder, with Consort Homes and Fischer & Frichtel also building, and McBride released a new phase of homesites in July 2026, so there are lots to choose from again.

There are ranch homes, villas, townhomes, and two-story designs.

This planned neighborhood has large green spaces and community lakes and is close to amenities like golf courses, shopping, and dining options.

Harvest is right down the street from The Meadows and Hawk Ridge shopping center.

Shady Creek

Shady Creek is an amenities-focused, master-planned neighborhood built primarily by Lombardo Homes. It is sold out as of 2026, so anything here is a resale.

17:1817 minutes, 18 seconds

Living St. Louis

The community area plans include a swimming pool, a lazy river, and a fitness center. These spacious homes boast 2620- 3965 square feet and 3-car garages.

Amberleigh

A Lombardo Homes community that is still selling in 2026, this neighborhood features a variety of home styles, including ranch, split-level, and two-story single-family homes.

Sizes range from 1,600 to over 4,000 square feet.

This community has community woodlands and an open outdoor space in the works.

Inverness, Enclave at Brookside and Phoenix at WingHaven

Lombardo has three newer O’Fallon communities worth knowing about. Enclave at Brookside is selling with a display home open. Inverness is nearly finished. Phoenix at WingHaven, a 30-lot plat the city approved in March 2026, is scheduled to open in fall 2026.

One to watch rather than shop: Lombardo’s Villages at Busch Wildlife, up to 239 homes on land the city annexed off Highway DD in August 2024, has been stalled by an annexation lawsuit, and as of early 2026 the plat was approved but nothing was moving.

Running Errands Made Easy on Highway K

State Highway K is the main artery through O’Fallon.

It runs north to south, giving you access to everything you need.

From grocery stores and car mechanics to movie theaters, restaurants, coffee shops, healthcare options, and more.

Driving down K, you’ll pass strip malls filled with familiar chain restaurants, stores, drugstores, and banks.

Despite all the chains, you’ll see a couple of local gems in the shopping centers.

Highway K has had a run of new restaurants since 2025 as well: Osteria Forto, MOOYAH, Mizu Hibachi Sushi & Ramen and Wicked Greenz all opened along K in 2025 and 2026, and Rosalita’s Cantina opened a 450-seat location just off it on Mexico Loop Road in 2026.

You’ll also find apartment communities like Prairie Point and Bramblett Hills, offering convenient living options in the heart of O’Fallon.

O’Fallon has excellent healthcare options.

Progress West Hospital is located right in O’Fallon, while SSM Health St. Joseph Hospital is nearby in Lake St. Louis. Additionally, BJC has medical offices in O’Fallon.

For those on the south-west side, Highway N offers a variety of groceries, shops, and restaurants, with more development happening in those areas to accommodate the new residential areas.

They also have live music and offer a kids’ menu.

Crossroads Brewery: This O’Fallon brewery has an extensive menu featuring all kinds of beer from German-inspired to sours and IPAs.

Shortleaf Brewing: Although technically in nearby Winghaven, this family-owned brewery features a full restaurant and bar.

Entertainment Around Town

18 North Central is where “grown-ups come to play with family and friends.” It offers axe throwing, laser tag, and a unique game called “CyberSport Demo Ball,” best described as lacrosse with bumper cars.

Sky Zone Trampoline Park is mostly geared toward families, and it’s exactly what the name says!

A massive, indoor trampoline park.

Ethyl’s Smokehouse and Saloon on Veterans Memorial Parkway is the late-night option, a barbecue joint and bar that stays open past midnight most nights.

The O’Fallon Hoots is O’Fallon’s own collegiate summer league baseball team! The games are affordable and fun for the whole family. And the home games are conveniently located in O’Fallon at CarShield Field.

CarShield Field also has special events when the O’Fallon Hoots aren’t playing. Food Truck Frenzy for food enthusiasts, the Tacos and Tequila Festival, and the 2nd Annual Battle of the Badges Baseball Classic (to name a few).

Community Events

O’Fallon has annual festivals that feature cultural activities, history, art, and family fun!

The Heritage and Freedom Fest is held annually around the 4th of July at the Ozzie Smith Sports Complex, July 1 to 4 in 2026, with fireworks on the 3rd and the 4th. There’s live music, vendors, rides, and more!

Fall into the Arts is held annually in September at the O’Day Amphitheater, on September 20 in 2026. It’s free to attend and features live music, artists, hands-on activities for the kids, and food vendors.

For the holiday season, there’s the Celebration of Lights through Fort Zumwalt Park, November 27 to December 30 in 2026, nightly from 6 to 9. This drive-through lighting extravaganza is a holiday tradition, $18 a car with tickets bought online in advance.

On certain nights you can also ride it by heated trolley, by hayride, or on select dates by the city train instead of driving.

And from spring to fall there is the Farmers & Artisans Market of O’Fallon, Sundays from 9 to 1 in the StorCo lot off I-70 and Highway K, April 19 through November 8 in 2026.

Parks & Recreation in O’Fallon

O’Fallon is a haven for outdoor enthusiasts with its parks, trails, sports fields, and nearby lakes giving residents plenty of options for indoor and outdoor activities.

Parks

Fort Zumwalt Park: This 48-acre shady park has a playground, disc golf, walking trails, and a scenic lake.

There’s also a rich history here!

There’s a restored historic home from 1884 and a rebuild of Zumwalt’s Fort. Fort Zumwalt Park is a great place for a picnic, a nature walk, or a nice place to sit and enjoy nature or historic sites.

Dames Park: Known for its athletic fields, this 59-acre park features three sports fields, two playgrounds, pickleball courts, pavilions, and a scenic walking and biking path.

Ozzie Smith Sports Complex is appropriately named for one of the Cardinals’ most famous shortstops, Ozzie Smith. This 76-acre sports complex has seven outdoor baseball/softball fields and is home to CarShield Field, where the O’Fallon Hoots play.

Veterans Memorial Walk is a place to reflect on history. With special events on Memorial Day, Armed Forces Day, and Veterans Day, this unique memorial draws visitors year-round.

In addition to these larger parks, O’Fallon has parks throughout the city, making it convenient to find a green space to enjoy: Civic Park, Knaust Park, O’Day Park, and Westhoff Park.

Two newer ones: the Twin Island Trailhead on Technology Drive, the latest section of the Dardenne Greenway, opened in June 2026, and O’Fallon Playfield Commons, a sports complex with a hotel, retail and a food-truck park next to the Justice Center on Bryan Road, is scheduled by its developer to open in January 2028.

Recreation

Whether you’re into fitness, need a fun spot for the kids, or want to connect at a community center, O’Fallon’s recreational facilities have something for everyone.

Renaud Center: a large indoor recreation complex with a fitness center, aerobics room, and swimming pool. Renaud Center is in Sports Park, which itself boasts 12 athletic fields and concession stands.

O’Fallon Park Rec Complex YMCA: This Y has it all, a fitness center, teen center, indoor and outdoor pools, indoor track, and steam room.

And let’s not forget our four-legged family members. O’Fallon has 15 off-leash dog parks in the O’Fallon area. Check it out!

Excellent Schools in O’Fallon

O’Fallon, Missouri, is served by three public school districts: the Fort Zumwalt School District across most of the city, the Wentzville R-IV School District on the west side, and the Francis Howell School District in portions of the east and south.

All three grade an A overall on Niche (2026), and which one a given address falls in is worth checking before you fall for a house, because the district lines do not follow the city limits.

Fort Zumwalt School District (FZSD): FZSD encompasses a significant portion of O’Fallon.

It has multiple elementary, middle, and high schools within the city.

All four of its high schools have been recognized among America’s Best by U.S. News & World Report for six consecutive years, ranking in the top 30 in Missouri.

The district scored 94.5% on its Annual Performance Report from the state, reflecting high academic achievement and growth.
