North Potomac, MD sits in Montgomery County, a residential suburb just northwest of Washington, D.C. Those buying a home in North Potomac almost always size it up against neighboring Gaithersburg at the same time - and that makes sense, because the two share zip codes, local infrastructure, and similar real estate trends.
The median household income is $186,514, and the housing market reflects that. Whether this area works for you comes down to one question: do the commute logistics and the housing stock justify what you'll pay in property costs and local taxes?
The Quick Verdict on North Potomac
Housing costs run 34% to 41% above the national average. You're paying for the location and what it buys you in terms of access to major employment hubs across the Washington, D.C. metro.
On the positive side, the housing stock ranges from single-family homes on larger lots to townhouses, major commuting routes are accessible, the local economy is stable, and the poverty rate is a low 5.3%. That's a genuinely solid baseline.
The concerns are affordability and property crime. The housing sub-index for the Gaithersburg and North Potomac market can reach up to 212 - meaning housing costs more than double the national baseline. Violent crime is below the national average, but property crime runs higher than it.
Factors to Weigh Before Moving
Traffic on Route 28 and Interstate 270 can make the daily commute feel longer than the map suggests. North Potomac is geographically close to D.C., but close on a map and close in drive time are two different things here.
You'll also want to budget for Montgomery County property taxes and, depending on the subdivision, homeowners association fees. Both are common, and both add real weight to your monthly carrying costs.
Where Is North Potomac and What County Is It In?
North Potomac is in Montgomery County, Maryland, tucked between Gaithersburg to the northeast and the Potomac River to the south. It's a census-designated place, not an incorporated city, so residents rely on Montgomery County for police, fire, public works, and most other municipal services.
One thing that trips people up: the area shares the 20878 ZIP code with parts of Gaithersburg. That means your mailing address may say Gaithersburg even if you're squarely within North Potomac boundaries.

How to Research Local Crime Data
The Montgomery County Police Department handles law enforcement for the area but doesn't publish a neighborhood-specific summary report for North Potomac alone. If you want street-level or subdivision-level detail, you'll need to do a bit of digging yourself.
The county's official Crime Incident Map is the right starting point, and the dataMontgomery portal gives you access to live, incident-level data you can run against any specific address you're considering.

North Potomac vs Nearby Alternatives
