City or county? What a Falls Church address means

"Falls Church, Virginia" on an envelope can mean two different governments. The City of Falls Church is an independent city of about 2.1 square miles and 14,658 people as of the 2020 census. Around it, a much larger area of Fairfax County uses the same Falls Church mailing address. The city's own examples are Merrifield, Seven Corners and Bailey's Crossroads: all get mail addressed to Falls Church, and none of them is in the city.

The difference is not a technicality. An independent city is not in the territory of any county, and 38 of the 41 in the United States are in Virginia. So the city runs its own schools, building permits and trash pickup. About two in three of the businesses in our directory carry a ZIP other than the city's 22046, and most of those are in Fairfax County. This guide explains how to tell which side you are on and what changes.

How to tell

The city publishes rules of thumb, and it says plainly that there are exceptions:

• The city's main ZIP is 22046, with a few city properties in 22042, 22044 and 22205. ZIP 22040 is for post office boxes.
• Most residential addresses in the city have three digits.
• Most addresses numbered 1400 and higher are outside the city, apart from a few spots where Arlington or Fairfax numbering carries into the city, mostly in the 6000s.
• An address written as Leesburg Pike, Route 7, Arlington Boulevard, Route 50, Lee Highway or Route 29 is probably not in the city. Inside the city, Route 7 is Broad Street and US 29 is Washington Street.

For a firm answer, the city's Address Finder page links a lookup tool it keeps current. It also suggests the Postal Service's ZIP lookup, which shows a "County" field under its mailing industry details, and a map that draws the jurisdiction lines. Eden Center is a good example of why the rules are only rules: it carries a 22044 ZIP and sits inside the city.

Schools

The city runs its own school system, Falls Church City Public Schools. It has Mount Daniel Elementary for kindergarten through second grade, Oak Street Elementary for grades 3 to 5, Mary Ellen Henderson Middle School and Meridian High School, plus the Jessie Thackrey Preschool. Mount Daniel itself sits outside the city limits, in Fairfax County. The city asks families to enroll children as soon as they arrive.

A Fairfax County address is in Fairfax County Public Schools. The county's boundary locator, on its schools website, shows the elementary, middle and high school assigned to an address. One name trips people up: Falls Church High School belongs to Fairfax County and does not serve the city.

Building permits

The city issues its own building permits from its office at 300 Park Avenue. Its homeowner guidance says you can paint, replace flooring and cabinets, swap windows and doors of the same size, reroof, and replace a sink, toilet, outlet or light in place without one. Any change to a wall needs a permit, load-bearing or not, and so does any work involving gas, even replacing a stove.

Fairfax County addresses go through the county's Land Development Services. Its list differs in places. The county, for example, says a direct replacement of a water heater, stove or HVAC unit needs a permit, while a like-for-like swap of a plumbing or electrical fixture does not. Our guide to hiring a contractor sets the two lists side by side.

Trash and recycling

Inside the city, Public Works collects refuse, recycling, yard waste, bundled brush, special bulk items and seasonal leaves from single-family homes and townhouses on public streets. Wednesday is waste day for every residential customer. Extra and special collections cost more.

In Fairfax County it depends on the street. The county itself collects from about 10 percent of residents, those living in sanitary districts, and bills them on the annual tax assessment. The other 90 percent of residents and businesses hire a private collection company, paid directly or through a homeowners association. The county posts a map showing which streets it serves.

Water, power and gas

Here the two sides mostly match. The city sold its water utility to the Fairfax County Water Authority in January 2014, and Fairfax Water now serves the city along with much of the county. The water for the city and nearby Virginia customers starts in the Potomac. The Washington Aqueduct, run by the Army Corps of Engineers, takes it in at Great Falls and treats it at its Dalecarlia plant. Dominion Energy supplies the electricity and Washington Gas the natural gas.

Metro

Neither Metro station with Falls Church in its name is inside the city. East Falls Church station, on the Orange and Silver lines, is in Arlington County in the median of I-66. West Falls Church station, on the Orange Line, is in Fairfax County, also in the I-66 median. I-66 runs just north of the city, and the Capital Beltway, I-495, a few miles west.

Your car

Virginia wants a safety inspection every 12 months, and cars kept in the city or in Arlington or Fairfax counties need an emissions inspection every two years. The city adds its own steps: a new resident registers the vehicle with the city's Commissioner of the Revenue after the state, and buys a city decal for any vehicle normally garaged in the city within 60 days. The city also licenses dogs, within 30 days of moving in.

Using our listings

Every listing in our directory shows its street address and ZIP, so the rules above apply to each one. Our About page explains why we cover the whole Falls Church mailing area rather than only the city. When a permit, a school or a trash day depends on the answer, check the address with the city's lookup, not with us.
