In order for the Simpson family to purchase the home, Abraham Simpson sold his old house and wrote Homer a check for $15,000, allowing him to pay the down payment on the house. In No Loan Again, Naturally it is revealed that the Simpsons are unable to afford their mortgage anymore, due to Homer constantly loaning money against the house, which causes Ned Flanders to buy the house for $101,000 and rent it to the Simpsons.
The house to the left of the Simpsons house is the Flanders' house, which is owned outright by Ned Flanders.
Marge once said that Evergreen Terrace is "the street that smells like pee". Oddly, former presidents George Bush and Gerald Ford have previously moved onto the street, albeit in a house across the street. The House has been destroyed, sunk and other problems have happened.
The house is a pinkish orange two-story detached house with a garage, basement, attic and lots of mice. On the ground floor, the front door leads straight into the foyer, with one arch in the wall to the left, leading to the sitting room, one to the right which leads into the dining room, a small cupboard and the stairs to the second floor. The sitting room and the dining room both have bay windows. At the back of the house is the living room and the kitchen, with stairs that lead to the basement (Marge discovered a secret sauna room hidden behind a heater).
The second story of the house has Homer and Marge's bedroom (with an en suite bathroom), Bart's bedroom, Lisa's bedroom, Maggie's bedroom, a bathroom and some 'empty' rooms, often shown in inconsistent places in several occasions. On the landing, there is a hatch which leads to the attic.
The back garden of the house is surrounded by a wooden picket fence and a low box hedge, and features a patio and the treehouse. Occasionally there is a hammock shown tied to two trees near the fence that borders Ned Flanders' backyard. Near that fence are the tombstones of The Simpsons' former cats: Snowball I, Snowball II, Snowball III, and Coltrane.
The basement always includes a washing machine and a clothes dryer and a large Olmec statue of a head, which was a present from Mr. Burns after Bart donated blood to him. However, the appearance of other features such as a furnace, ping-pong table, air hockey set and water softener vary from time to time. The basement is often used as a "secret lair", where Homer has brewed alcohol to beat prohibition and hidden his superhero operation as Pie Man, and where Marge hid during a spell of agoraphobia. Marge discovered a sauna in the basement, hidden behind a water heater. At one time the basement held gym equipment. In one episode, Homer made his jerky business with Bart in the basement.
The house has two identical red sofas: One in the sitting room and one in front of the TV in the living room (that is sometimes seen with an indentation after Homer gets up) - the current sofa is a replacement of the old one which was destroyed (and had a fold-out bed the new one does not have). A tank full of fish is sometimes seen in the dining room.
A simple painting of a boat hangs on the wall above the living room couch - Marge once says that she painted it for Homer, but later it's suggested that she bought it, and it is titled "Scene from Moby Dick". She keeps many copies in a nearby closet to replace the original if it gets damaged, which is rare.Marge also has a whole drawer of her pearl necklaces (which Marge says are family heirlooms), shown when one is stolen by the Cat Burglar. The house does not have an air conditioner although there is one on the Lego Simpsons House and on the side of the house in Brick Like Me.
The house itself is often shown as dilapidated; the walls are painted with enough lead paint to double as a bomb shelter, the roof leaks and the kitchen was so badly damaged that it needed to be rebuilt. The interior of the walls are often shown to be filled with dangerous and unusual items such as asbestos, toxic waste, hidden treasure, recording devices, baby dinosaurs and dancing mice. Even the family cat, Snowball II, is seen in between the walls from time to time. It was also once stated that the walls were so fragile and so thin that various family members could overhear another conversation, and simply punching the wall is enough to put a hole through it. Also, Homer notes once that the grass on their lawn is actually just green painted cement (although in other episodes it is clearly grass). Despite the poor conditions, the lived-in spaces are usually kept neat by home-maker Marge. It was described as a palace by Frank Grimes, and Moe Szyslak observed that it contained no silverfish. The worst condition the house has been in was where it became horrifically slanted, which Bart uses as a sideshow, needing $8500 to repair, which Marge covers by getting a job.
Once, Homer had to re-shingle the roof on Sunday as part of his chores with Bart, but while trying to dare Bart to touch climb the TV antenna, and try to hang on while emulating an earthquake cumulating in trying to hammer Bart's grip on the gutters, only for the portion of the roof he was on to cave below him, collapsing and causing Homer to fall down.
The phone number is inconsistent, though always starting with 555. The area code was 636 before the town became too large and had to use two different area codes, changing the area code to 939.
When Springfield was trapped inside a dome during the Trappuccino crisis, an angry mob converged onto the house as a part of their effort to kill Homer Simpson, who was responsible for the town's ordeal. The house is completely devoured and destroyed with all possessions lost after a sink hole in Maggie's sandpit expands when the police shot bullets into it (the Simpsons family escaped through the sinkhole). After the dome was destroyed, the townsfolk and the family rebuild the house in exactly the same manner as it was before, restoring the "status quo" and Russ Cargill the head of the EPA is been deposed by US authorities for trying to blow up the town, tricking the president and attempted to kill innocent peoples.
The house's address was inconsistent (particularly in the older seasons of the show), being 94 Evergreen Terrace, 1094 Evergreen Terrace, 555 Evergreen Terrace, 723 Evergreen Terrace, and 430 Spalding Way. On the episode, "Homer's Triple Bypass", 742 Evergreen Terrace is shown to be a completely different house where Snake hides from the police and Rev. Lovejoy lives next door,
but the most common address used is 742 Evergreen Terrace.
In “Regarding Margie”, Bart, Nelson and Milhouse paint the Flanders' house number as 738 and the Simpsons' house as '74' and since Homer refuses to pay, they don't paint the last number. By common sense it should be 740 Evergreen Terrace.
An episode set in 2010 shows a wooden add-on to the second floor, built (rather poorly) by Homer in what appears to be a poor and very cheap attempt to upgrade his house in a fashion similar to all the other homes in the neighborhood. It functions as a guest bedroom, but Homer warns Lisa and her fiancé that "If the building inspector asks, it's not a room. It's a window box".
In the Simpsons "Treehouse of Horror VI" episode, there is a portal behind the bookcase in the sitting room that leads to the Third Dimension. This is a reference to The Twilight Zone episode, "Little Girl Lost". In Treehouse of Horror IV, the famous Dogs Playing Poker painting appears above the sofa. A similar house to the Simpson one also appears in the ending of Treehouse of Horror VIII, which Homer egged and broke the windows to get candy only for Lisa to point out that it was their house, making the rest of the trick-or-treaters laugh at the family.
A real life Simpsons house was constructed at 712 Red Bark Lane in Henderson, Nevada, built in 1997 by Kaufman and Broad Home Corporation in a promotion sponsored by FOX and Pepsi. The house was painted and furnished with items to match the television show, including what appears to be a 1997 Toyota Camry matched to look like Homer's Car, although the scale of the house was smaller than the house on the series. The house was given away in a contest; the winner, Barbara Howard, was a retired factory worker from Richmond, Kentucky. The house has since been repainted. The Simpsons House took 49 days to build, cost $120,000 and was unveiled to the public on August 1, 1997.
↑The Trouble with Trillions Homer: OK, I need some deductions, deductions... ah! Business gifts! [Homer grabs the boat painting from above the couch and hands it to Marge.] Here you go, keep using nuclear power! Marge: Homer! I painted that for you!
