Chestnut Hill's primary zip code is 19118, as confirmed by the USPS. Located in Northwest Philadelphia, this designation covers a single neighborhood but contains two very different housing markets. The gap between townhouse and single-family prices is wide, yet buyers pay nearly the same rate for the space: around $389 per square foot for a townhouse and $400 for a detached house. Those buying a home in Chestnut Hill, Philadelphia, PA can review our property breakdown for additional context.
Despite that gap in total price, a smaller budget in 19118 buys you less square footage, not a discount on the location. One more thing worth flagging before you dig in: the Census Bureau's "Chestnut Hill CDP" data often confuses this area with other places, and this neighborhood is entirely distinct from Chestnut Hill, Massachusetts.
Key takeaway
Chestnut Hill's zip code is 19118, and the neighborhood is in Philadelphia County. If your budget is under $1 million, start with townhouses; at that median they cost far less overall for nearly the same price per square foot as a detached house, so the alternative buys space, not a better rate. Before trusting a "19118" or "Chestnut Hill" label on a listing, confirm the address is inside the city line and the neighborhood.
Who this guide is for
You have a Chestnut Hill address, listing, or home search in front of you and need to confirm its zip code and county, then decide whether a townhouse or a single-family house in 19118 fits your budget and timeline.
Chestnut Hill zip code boundaries
The City of Philadelphia's Streets Department notes that postal zip code boundaries are modified for mail delivery and do not perfectly match the city's official neighborhood maps. A 19118 address tells you how the mail is routed. It does not guarantee a home sits inside the actual Chestnut Hill neighborhood.
Listings near the edges often borrow the Chestnut Hill name to attract buyers. Check the cross streets and the county lines before making an offer.
19118: Chestnut Hill
The 19118 zip code covers the core of the neighborhood, including the Germantown Avenue commercial strip and both of the SEPTA Regional Rail lines that end here, Chestnut Hill East and Chestnut Hill West. It also contains the Chestnut Hill Historic District, which encompasses 1,920 acres and landmarks like the Anglecot mansion and Graver's Lane Station.
The catch is that the zip boundary and the neighborhood boundary are drawn by different bodies for different purposes. A 19118 address is a start, not proof. Confirm the neighborhood and any historic-district listing through the city's property and historic-register lookups, and compare neighborhoods by home type to see where specific properties sit.
19119: The Mount Airy side
To the southeast, Chestnut Hill shares a boundary with Mount Airy along the Cresheim Valley. Homes on the Mount Airy side of this line fall into the 19119 zip code, and listings near this boundary are often marketed as "Chestnut Hill border" or "Chestnut Hill adjacent."
What that means for pricing: the figures on this page don't describe those homes. The 19119 code belongs to Mount Airy, so if you're pricing a 19119 listing, ask for Mount Airy comparables.
19038 and nearby codes across the county line
The Philadelphia city limits run along Northwestern Avenue and Stenton Avenue at the edge of Chestnut Hill. Neighbors on opposite sides of those streets can pay taxes to entirely different governments. Just past the city line sits Springfield Township in Montgomery County, which includes zip codes like 19038 for Wyndmoor, as well as Erdenheim and Flourtown.
Nothing on this page prices the Montgomery County side, and its taxes and schools work differently. Compare the actual tax bill and check the school district by address before treating a 19038 listing as a Chestnut Hill substitute.
What county is Chestnut Hill in?
Chestnut Hill is in Philadelphia County. Since 1854, Philadelphia County has been coextensive with the City of Philadelphia, meaning the city and the county share the exact same boundary and government structure.
Because you're buying in Philadelphia, the city's Office of Property Assessment handles your real estate taxes. The combined city and school district real estate tax rate is currently 1.3998% of your home's assessed value. Residents are also subject to the Philadelphia resident wage tax, which sits at 3.735% as of July 2026.
Public schools in the neighborhood are run by the School District of Philadelphia. Don't assume an address is zoned to a particular school based on the zip code alone; always use the district's school finder with the exact street address. For more detail on the costs of ownership and what it's like to buy and live here, review your budget with a local lender.
Chestnut Hill home prices in 19118
The pricing figures below reflect Redfin data for the specific Chestnut Hill neighborhood boundaries over the 90 days ending September 30, 2026, rather than the broader 19118 zip code. Because these property types rest on small samples of fewer than 30 sales each, treat them as a general direction rather than an absolute rule. You can review broader housing market trends and outlooks to see how the area compares to the rest of the city.
Townhouses in 19118
Townhouses represent the lower entry point for a Chestnut Hill address. These attached homes move quickly, showing a median of just 22 days on market based on 17 recent sales. With only 2.1 months of supply available, you'll want financing and inspection plans sorted before you start touring.
The rate per square foot is almost identical to a detached house, so the savings come entirely from buying less space, not from getting a better deal on the location.
Single-family homes in 19118
Detached houses in the neighborhood recently sold for a median price of roughly $2 million (based on 11 sales). They sit on the market longer than townhouses, a median of 35 days, yet still close well above asking at an average of 104.6% of list price. A longer time on the market here doesn't translate to a lower price.
Many of these properties are older, so buyers should review guidance on buying a historic home to understand inspection and insurance requirements. That median rests on a thin base, and one large estate sale can move the number considerably; the large year-over-year jump in the list below likely reflects which specific houses sold rather than the market rising that fast. Ask for recent comparable sales on the specific street you're targeting.
How to narrow your search in 19118
To evaluate a property in the 19118 zip code, ask yourself these four questions:
- Is the address inside Philadelphia or just over the line in Montgomery County? Check the zip code and the city's property record first to confirm your tax and school district status.
- Do you need a detached house, or would less space at the same price per square foot work? Townhouses cost far less overall, but they offer less square footage at a nearly identical rate per square foot.
- Do you need to buy quickly, or can you wait for the right house? Townhouses move faster and have thinner supply, while single-family homes sit longer but still sell over the asking price.
- Will you want to change the exterior? A 19118 address doesn't tell you whether the home is on the local historic register. Review the historic district rules before planning any renovations.
