Chicagoland, explained to newcomers

Adopted in 1917, the Chicago flag reads like a map. The three white bands are the North, West, and South Sides. The two light blue stripes are the water: the top one stands for Lake Michigan and the North Branch of the Chicago River, the bottom for the South Branch and the canal that linked the river to the Mississippi watershed.

The four red stars are the city's defining events, in the order they sit on the flag: Fort Dearborn, the frontier outpost where the city began; the Great Fire of 1871, after which Chicago rebuilt itself into the birthplace of the skyscraper; the World's Columbian Exposition of 1893, the fair that introduced the city to the world; and the Century of Progress fair of 1933. Look closely and you will see each star has six points, not five, chosen deliberately so they would never be mistaken for the stars on the national flag. The flag started with just two stars; the Century of Progress star was added in 1933 and the Fort Dearborn star in 1939, which is why you will occasionally hear a campaign for the city to earn a fifth. Chicagoans fly it like a family crest, on porches, on t-shirts, and in a remarkable number of tattoos.

State and Madison downtown is zero-zero. Addresses count outward from there, and eight blocks equal a mile, so 3200 North is exactly four miles north of Madison, every time, on every street. And every big number has a name: 800 West is Halsted, 2400 West is Western, 1600 North is North Avenue, 2400 North is Fullerton, 3200 North is Belmont, 3600 North is Addison, and 3500 South is 35th Street, where the Sox play. This is why an address works like a map here: tell a Chicagoan that Wrigley Field is at Clark and Addison, and they know it sits exactly four and a half miles north of downtown without looking anything up. Once this clicks, you can navigate the whole city from an address alone.

Each line is a mile street. Type an address (or an intersection) to see where it falls, or click anywhere on the map to read the coordinates. Hover a line for its number.

Disoriented? Find the water, or the skyline, or the direction the streets count toward. Locals give directions in cardinal terms ("it's on the north side of the street, just west of the L stop") because the grid makes them meaningful.

Chicago runs one of the largest alley networks in the world, close to two thousand miles of it. Garbage, garages, utility poles, and moving trucks live in back, which is why street parking exists and streetscapes stay tidy. Your dumpster is in the alley; so, often, is your parking spot.

Neighborhood identity is real here: people say Logan Square, Bridgeport, or Beverly before they say Chicago. When you tour homes with us, you are choosing a neighborhood at least as much as a building, and our building types guide tells you what each one is likely made of.

An 1836 declaration that the shoreline remain "forever open, clear and free" stuck. The result is roughly 26 miles of continuous public parks, beaches, and trail along Lake Michigan, one of the largest freshwater lakes on Earth. No private beachfront walls off the water here.

Every beach on the lakefront belongs to the public and costs nothing to visit. Beach season runs from the Friday before Memorial Day through Labor Day, with lifeguards on duty 11 am to 7 pm. North Avenue Beach is the famous one with the skyline view, Oak Street is the Gold Coast's front yard, Montrose has the sprawl and the dog beach, and 57th Street and Rainbow hold down the South Side. The Chicago Park District's beaches page lists all 27, with daily swim advisories in season.

In 1900 the city reversed the Chicago River so it drains away from the lake, protecting the drinking water. It remains one of the most audacious pieces of civil engineering in American history, and the reason the river is now lined with cafes instead of outfalls. Once a year it gets dyed green anyway.

The lake makes its own weather: spring days can be twenty degrees cooler at the shore than at O'Hare, and in winter the lake moderates the cold near the water. Weather apps here are neighborhood-specific, and so is your heating bill; our house systems guide explains what you will be running.

The CTA, the Chicago Transit Authority, runs the city's trains and buses: eight color-named L lines and well over a hundred bus routes. The Red and Blue lines run 24 hours, which few American systems can say. The "L" is short for elevated, and the Loop, the downtown circuit of elevated track, named the whole downtown. Both airports sit on L lines, O'Hare on the Blue and Midway on the Orange. The official CTA map is worth a bookmark.

Metra is the commuter railroad: 11 lines fanning out from downtown to more than 240 stations across the region, the trains suburbanites ride to work and back. If you are house hunting in the suburbs, walking distance to a Metra station is a real line item in a home's value, and we treat it that way. The Metra system map shows every line and station.

Buses and trains here report their positions live. The CTA's official Bus and Train Trackers show arrivals to the minute, Metra runs a tracker of its own, and Google Maps has a transit tab that folds all of it into door-to-door directions. Checking the tracker before putting your shoes on is a Chicago winter survival skill.

City residents buy an annual city vehicle sticker, many blocks require a residential zone permit to park (look up any address on the city's site), and overnight winter parking bans on snow routes are enforced whether or not it snowed. We check the parking reality of every listing we tour with clients, because it changes what a home is worth living in.

After a heavy snowfall, Chicagoans who dig their car out of a street spot claim that spot with whatever furniture is handy: lawn chairs, ironing boards, milk crates, the occasional bar stool. This is Dibs. It appears in no ordinance, the city officially discourages it and hauls the chairs away once the snow melts, and it is enforced anyway by a court of public opinion that has been in session for decades. Our advice for your first winter: shovel your own spot, and leave the chairs alone.

O’Hare International, on the far Northwest Side, is perennially among the busiest airports on earth, with nonstops to most of the world. The Blue Line runs 24 hours from the Loop into a station inside the terminal core, about 40 to 45 minutes, and the Kennedy is the driving route. The neighborhoods along that corridor, Jefferson Park especially, treat the airport as a fifteen-minute amenity.

Midway sits inside the city at 55th and Cicero, a compact square-mile field that Southwest Airlines calls a fortress. The Orange Line runs from the Loop to its door in about 25 minutes, which is why South Loop, Bridgeport, and Archer-corridor addresses brag about it. Domestic-heavy, quick through security, and often the cheaper fare of the two.

Chicago Executive Airport (PWK) in Wheeling handles the corporate and private traffic for the north suburbs; DuPage Airport (DPA) in West Chicago does the same for the west, with one of the longest general-aviation runways in the region; Waukegan National (UGN) covers the far north shore; and Gary/Chicago International (GYY), just over the Indiana line, is minutes from the South Side and hosts the region’s airshow traffic. None run scheduled airline service to speak of, but they are why the sky over Chicagoland is never empty.

Chicago Rockford International (RFD), about 90 minutes west, pairs a handful of low-fare leisure routes with one of the country’s major air-cargo operations. And Milwaukee Mitchell (MKE), 90 minutes north, is the quiet pro move for north-suburban travelers: full airline service, small-airport lines, and Amtrak trains from Chicago that stop at the airport’s own rail station.

Before O’Hare took the crown in the early 1960s, Midway held it, and before either, the site of O’Hare built C-54 transports during World War II under the name Orchard Field, which is why your luggage tag still says ORD.

Deep dish is real and worth the pilgrimage, but the everyday Chicago pizza is tavern-style: cracker-thin, cut in squares. Ordering "a thin crust, square cut" is the quickest way to sound like you have lived here ten years.

A Chicago dog is an all-beef frank dragged through the garden: mustard, onion, relish, pickle, tomato, sport peppers, celery salt, poppy-seed bun. Ketchup is not part of the arrangement.

The other local food group was born in Chicago's Italian immigrant neighborhoods during the Depression, when South and West Side caterers stretched a scarce roast by slicing the beef paper-thin, simmering it in seasoned jus, and piling it high on bread so one roast could feed an entire wedding. The economy trick outlived the hard times, moved to street stands, and became the city's signature sandwich.

Ordering has its own language. "Sweet" means roasted green peppers, "hot" means spicy giardiniera, and "dipped" means the whole assembled sandwich takes a quick bath in the jus. Go dipped, then eat it the way locals do: leaning forward, elbows on the counter, feet well back, so the drippings land on the wrapper instead of your shirt. That posture is called the Italian stance, and nobody warns you about it until it is too late.

Jeppson's Malört is a wormwood liqueur brought to Chicago by Swedish immigrant Carl Jeppson, who sold it during Prohibition as medicine, which the taste makes believable. It is bracingly, famously bitter, and the grimace after a first sip is such a tradition it has a name: Malört face. Locals order it for newcomers as a welcome, a prank, and a loyalty test, all at once. After decades of being distilled out of state, it is made in Chicago again, and a shot of it next to an Old Style has its own name too: the Chicago Handshake. Congratulations, you live here now. Full disclosure: some of The Boulevard Group drink it by choice and insist it is not as bad as everyone says. The face is optional.

From June through September the city lives outside: free music festivals in Grant and Millennium Park, movies in the parks, street festivals in nearly every neighborhood every weekend. We keep a month-by-month guide at our Chicago Festival & Event Calendar.

The Chicago Region Trees Initiative at the Morton Arboretum maps tree canopy across the whole region, block by block: the interactive canopy map. It is a surprisingly useful house-hunting layer: mature trees mean shade, summer cooling, and streets that felt finished decades ago.

Through the city's Our Roots Chicago program, Chicago residents can request a free tree for the parkway in front of their home, planted by the city. Requests go through 311's tree planting service. It is one of the best free upgrades a new homeowner can order.

Illinois income tax is a flat 4.95%, and there is no city income tax on top. Sales tax in Chicago is 10.5% all-in (6.25% state, 1.75% Cook County, 1.25% city, 1.25% transit), among the highest of any big American city, and often a point or two lower in the suburbs. Property taxes are the big one: Illinois rates are among the highest in the country and differ meaningfully by county and town, which is why we pull the actual tax bill for every home we show. The lookup links live in the Taxes & government section of our resources page.

Cook County bills this year's taxes next year, which is why buyers receive a tax credit from sellers at closing. It confuses everyone exactly once; the county tax links on our resources page and your attorney make it painless.

Two-flats, greystones, workers cottages, and bungalows are not just charming words, they are different machines with different maintenance lives. Our Field Guide to Chicago Buildings teaches you to read them, and our Home Buyer School walks the whole purchase in order.
