If you’re driving down MacDade Boulevard and blink, you might miss it. Honestly, Folsom is one of those places that people often lump in with Ridley Park or Milmont Park without a second thought. But if you live in zip code 19033, you know better. It’s a small, sturdy slice of Delaware County—Delco, if we’re being real—that manages to feel like a neighborhood where time slowed down just enough to keep things neighborly, even while the rest of the Philadelphia suburbs got frantic.
Folsom isn't fancy. It doesn't try to be Main Line. It's a place of brick twins, sprawling Ridley High School pride, and some of the best hoagies you’ll find in the tri-state area. When people search for Folsom PA, they’re usually looking for one of two things: a place to buy a house that won’t bankrupt them or the specific boundaries of the 19033 zip code.
The Weird Geography of Zip Code 19033
Geography in Delco is always a bit of a mess. You’ve got boroughs, townships, and "census-designated places" all overlapping like a dropped deck of cards. Folsom PA is technically part of Ridley Township.
The 19033 zip code is compact. It’s bounded roughly by Morton to the north, Woodlyn to the south, and Holmes to the east. It's essentially the heart of the Ridley community. If you’re looking at a map, it’s centered around the intersection of Morton Avenue and MacDade Boulevard. This is where the local pulse is. It’s not a massive area, covering just about 1.2 square miles.
Most people don't realize that while Folsom has its own identity, it shares a lot of its DNA with the surrounding Ridley patches. You might live in Folsom but your kids go to Ridley High, which is technically located right there in the 19033 zone. It’s the hub.
Is it Folsom or Ridley?
That depends on who you ask.
If you’re mailing a letter, it’s Folsom.
If you’re talking sports, it’s Ridley.
The Green Raiders are the soul of this zip code. On a Friday night in the fall, Phil-Olden Field is the only place that matters. The loyalty to the school district here is intense, bordering on a religion. You'll see the "R" logo on car magnets, hoodies, and even some local business windows. It creates a sense of belonging that's hard to find in the more transient suburbs closer to the city.
Real Estate Reality in Folsom PA
Let's talk money and houses.
People are flocking to Folsom PA because, frankly, the rest of the Philly suburbs have become ridiculously expensive. In 19033, you can still find a solid, well-built brick twin or a modest single-family home for a price that doesn't feel like a joke.

According to recent Bright MLS data and local real estate trends, the median home price in Folsom often hovers significantly lower than the national average for "desirable" suburbs, yet the area maintains a high rate of homeownership. People buy here and stay for thirty years.
- The inventory is mostly older stock. Think 1940s and 50s builds.
- Lots are smaller, which means you actually have to talk to your neighbors.
- Property taxes are a major conversation piece—it's Delco, after all.
The market here is fast. Because it’s an entry-level sweet spot for many first-time buyers, houses in 19033 often go under contract in less than a week. It’s a "working-class professional" vibe. You’ve got nurses, tradespeople, and city workers who want a backyard for their dog but still need to be able to jump on I-95 or the Blue Route (I-476) in five minutes.
Life on MacDade: The Local Economy
MacDade Boulevard is the spine of the community. It’s not pretty—it’s a commercial strip—but it’s functional. You have your standard Wawa (multiple, obviously), but you also have local staples that have survived for decades.
Take a look at the dining scene. You aren't coming here for Michelin stars. You're coming here for a cheesesteak that actually has flavor. Places like Leo’s Steak Shop (just over the border in Holmes but a staple for Folsom residents) or the local pizzerias define the palate here.
There's a specific kind of toughness to the businesses in zip code 19033. They are community-oriented. You'll find a local hardware store where the guy behind the counter actually knows how to fix your leaking sink. It’s that kind of place.
The Commuter Factor
If you work in Center City Philadelphia, Folsom is a strategic choice. The SEPTA Regional Rail is your lifeline. The Wilmington/Newark Line has stops nearby (like Ridley Park or Crum Lynne), making the commute roughly 25 to 30 minutes.

Traffic on MacDade, however, is a different beast. It can be a nightmare during rush hour. Local tip: learn the backstreets like Swarthmore Ave or Franklin Ave to bypass the gridlock near the Ridley High School entrance when school lets out.
Why 19033 Stands Out
What most people get wrong about Folsom PA is thinking it’s just another boring suburb. It’s actually quite vibrant in its own quiet way.
The Ridley Township Public Library is a massive resource located right in the heart of Folsom. It’s more than just books; it’s a community center. They host everything from kid’s programs to senior social hours.
And then there’s the parks. Catania Park is a local gem. It’s where the Little League games happen, where people walk their Golden Retrievers, and where the community gathers for fireworks. It’s the kind of place where you’ll see three generations of a family sitting on the same bleachers.
Challenges and the "Real" Folsom
It’s not all sunshine and low-interest rates. Folsom faces the same issues many "inner-ring" suburbs do. Infrastructure is aging. Some of the roads look like they’ve been through a war zone after a rough winter.
And because it’s so densely populated, parking can be a headache if you’re living in one of the twin-home blocks. You learn to be precise with your parallel parking.

But the trade-off is the safety and the schools. Ridley School District consistently performs well, and the sense of security in Folsom is a major draw. You still see kids riding bikes to their friends' houses. That's becoming a rarity in many parts of the country.
Actionable Steps for Moving to or Living in Folsom
If you’re looking at Folsom PA as a potential home or just trying to navigate the area better, here is the ground-level advice you actually need.
Check the Flood Zones
Some parts of Ridley Township, particularly those near Muckinipattis Creek or Darby Creek, can be prone to flooding during heavy Delco rains. Before you fall in love with a house in 19033, check the FEMA flood maps. It could save you a massive headache—and a huge insurance premium—later.
Join the Local Groups
Forget the big news sites. If you want to know what’s actually happening—like why there are sirens on MacDade or which plumber is honest—join the "Ridley Township Community Group" on social media. It’s raw, it’s unfiltered, and it’s the fastest way to learn the local landscape.
Visit the Hidden Green Spaces
Don't just stick to the main roads. Explore the Ridley Marina nearby or take a walk through the quieter residential blocks north of MacDade. You’ll find pockets of Folsom that feel incredibly secluded despite being in the middle of a bustling county.
Understand the Taxes
Delaware County recently went through a reassessment. If you are buying in 19033, don't just look at what the current owner is paying. Look at the most recent assessment values on the county website to get an accurate picture of your future monthly payment.
Support the "Mom and Pops"
The local economy in Folsom thrives on small businesses. Skip the big chain for your morning coffee or your Friday night pizza. The longevity of this community depends on the local spots that have been there through thick and thin.
Folsom PA is a place that rewards those who look closer. It’s a neighborhood built on hard work, school pride, and a refusal to be anything other than exactly what it is. Whether you’re moving into zip code 19033 for the first time or you’ve been here since the 70s, there’s a shared understanding that this little corner of Delco is a pretty good place to call home.
