North Baltimore, MD ZIP Codes: City Lines, County Lines, and Home Prices in 2026
Finding a home in the northern neighborhoods of Baltimore City means getting comfortable with local boundaries first. The line between the city and the county isn't always obvious from a mailing address alone. If you are buying a home in North Baltimore, MD, review our local property page.
Property taxes and school zones shift depending on which jurisdiction a home falls into, so confirming the exact location matters before you start comparing prices. The housing market also moves at different speeds depending on property type.
Key takeaway
North Baltimore is covered mainly by ZIP codes 21209, 21210, 21211, 21212, 21214, 21218, and 21239, but some of these cross into Baltimore County, so you should confirm an address's jurisdiction before comparing prices. For the most space per dollar, start with townhouses, which make up most of what's for sale. If you need a detached house, plan to pay asking or more: single-family homes sold at 100.5% of list price in the 90 days ending Sept. 30, 2026.
Who this guide is for
You're looking at homes in the northern part of Baltimore City and need to know which ZIP code, and which side of the city-county line, a listing sits on before you compare prices.
What ZIP codes are in North Baltimore?
A North Baltimore, MD ZIP code tells you where your mail goes, not what you'll pay. Some of these ZIP codes cross the line between Baltimore City and Baltimore County, which sets your tax rate and school system. The bigger divide in price and negotiating power, though, is by home type: townhouses sit at 5.5 months of supply, leaving buyers far more room than single-family homes at 2.5 months.
North Baltimore generally refers to the northern neighborhoods of Baltimore City, distinct from the communities in northern Baltimore County. Moving west to east, the area begins with 21209 around Mount Washington and 21210 around Roland Park. In the center you'll find 21211 covering Hampden and Remington, alongside 21218, which includes Charles Village and Waverly. Further east, the map shifts to 21212 for Homeland and Govans, 21239 for the Northwood area, and 21214 covering Hamilton and Lauraville. Neighboring ZIP codes 21213, 21215, and 21217 sit just outside this main cluster and are covered in the FAQs below.
ZIP codes that cross into Baltimore County
Several North Baltimore ZIP codes extend past the city line. The boundaries for 21209, 21212, 21239, and 21214 all spill over into county territory, which means two homes on nearby streets can share a ZIP code but carry different tax rates, transfer costs, and school systems.
Neither the ZIP code nor the mailing city on a listing settles which jurisdiction you'd be buying in. A "Baltimore, MD" mailing address doesn't guarantee a Baltimore City home: USPS uses the Baltimore place name for many addresses that are legally in Baltimore County. Only a parcel lookup confirms the location, so check every split-ZIP listing before comparing it with others.
How to check whether an address is in Baltimore City or Baltimore County
You can confirm the jurisdiction for any address using the Maryland SDAT real property search. This public database requires you to select a specific county or Baltimore City manually before searching by street address. It doesn't search by ZIP code or neighborhood. Use the property's current assessed value from SDAT, not the list price, to estimate the tax bill, and ask which credits the seller currently receives.
The difference in annual property taxes is substantial. For fiscal 2027, Baltimore City's real property tax rate is $2.248 per $100 of assessed value, while Baltimore County's rate is $1.10 per $100. On a townhouse assessed at $255,000, the recent median sale price for that property type, the city tax bill would be roughly $5,732 before credits, compared to $2,805 in the county.
Transfer and recordation taxes also differ by jurisdiction, which changes your closing costs. Baltimore City charges a 1% recordation tax and a 1.5% local transfer tax. Baltimore County charges a $2.50 per $500 recordation tax and a 1.5% transfer tax that excludes the first $22,000 for residential transfers. Both jurisdictions collect the 0.5% state transfer tax.
School assignments follow these same boundaries. Check school assignment for the exact address with the relevant district's lookup tool rather than relying on the ZIP code or the listing.

North Baltimore housing market by home type
Townhouses make up most of the market and most of your choices: 153 of 296 recent sales. At $176 per square foot against $248 for single-family homes, they offer about 29% more space per dollar. The median townhouse sold in 33 days, so well-priced ones still move within about a month, while stale listings leave room to negotiate. One thing worth asking: whether a rowhouse sits in a Baltimore City historic district, which can govern exterior changes.
Single-family homes are much harder to secure. The median price reached $532,412, 31.3% sold above list, and there are only 72 active listings. Come with a pre-approval ready and expect competition.
Values rose modestly across all types over the past year, so any negotiating power you have comes from the property type rather than falling prices.
Condos offer the most room to negotiate below asking, based on a smaller sample of 46 sales. They sat on the market for a median of 49 days, closed at 98% of list price, and only 11% went above asking. Condo space costs $201 per square foot, which is higher than townhouses even though the median condo price is lower: that indicates smaller units rather than cheaper space. For condos, ask the association for current monthly fees, what they cover, and whether the building is FHA-approved.
How to narrow your North Baltimore search
If the tax rate, transfer costs, or school system will affect your budget, start with listings in the ZIP codes that cross the city line and check them one by one in SDAT. That gives you a shot at a Baltimore County tax rate with a North Baltimore-area address.
From there, decide whether you need a detached house or whether a rowhouse or townhouse would work. The answer changes both your price per square foot and how hard you'll compete. If square footage is the priority, start with townhouses and rowhouses. If you need a detached single-family house, focus there, have your pre-approval ready, and be prepared to move fast.
Finally, think about how much room you want to negotiate. Condos offer the highest likelihood of closing below list price. Mike Fielder of Cummings & Co Realtors can pull recent sales for a specific address on either side of the city-county line to help you structure an offer.
