Neighborhood guidance in Gaithersburg

School and tax boundaries in Gaithersburg seldom line up with a mailing address. The Census Bureau’s 2020-2024 survey counts 47,217 housing units across ZIP codes 20877, 20878 and 20879. Of those, the incorporated city holds 27,280. A mailing address alone tells you very little. Everything else shares the postal name but answers to Montgomery County for taxes, permits and licensing.

That municipal line is old. Gaithersburg incorporated on April 5, 1878, became a city in 1968 and today spans about 10 square miles. Owners within it pay a city rate of $0.262 per $100 of assessed value, billed beside the county and state amounts. Past the line, that charge drops away and county services take over. Facing houses on a boundary street can receive different bills.

Schools follow a third map. Montgomery County Public Schools draws its own attendance zones and publishes a lookup by street address. Those zones ignore both the city limit and the ZIP code. What a neighbor reports says little about the house you’re eyeing, so we look up each address on your list individually. School assignments can also shift when the school system redraws zones after a boundary study. We note the date of each lookup. A listing’s school claims get checked against the official source, never taken from marketing copy.

For each address you send, we return the assigned schools, the taxing jurisdiction, any special charges and whether city codes apply. Neighborhood guidance explains the method.
