An apartment is a single unit within a building owned by a landlord or property company
An apartment is a self-contained living space — usually one or more bedrooms, a kitchen, bathroom, and common areas — located inside a larger building with other similar units. You rent it from a landlord or property management company, not own it. The building itself, the roof, the walls between units, the hallways, and the grounds are owned and maintained by someone else. You pay rent each month for the right to live there, and the landlord is responsible for structural repairs and upkeep.
The key difference between an apartment and a house is ownership and maintenance responsibility. When you rent an apartment, you are responsible only for the inside of your unit — keeping it clean, not damaging walls or fixtures, following lease rules. The landlord handles everything outside your door: roof leaks, foundation problems, parking lot repairs, hallway lighting, pest control in common areas. With a house, whether you own or rent it, you or your landlord typically handle all maintenance, inside and out.
Key Takeaways
- An apartment is a rental unit inside a larger building where a landlord owns the structure and handles major repairs.
- You are responsible for keeping your unit clean and undamaged; the landlord maintains the building itself, roof, and common areas.
- Apartments usually cost less upfront than houses because you do not pay for land or structural maintenance.
- Lease agreements set the rent amount, lease term, and rules you must follow while living there.
- Apartments differ from condos (which residents own) and houses (where you own or rent the entire structure and land).
How apartment rent and leases work
When you rent an apartment, you sign a lease — a written contract between you and the landlord. The lease states how much rent you pay, when it is due (usually the first of the month), how long you can live there (typically one year), and what rules you must follow. Common rules include no loud noise after certain hours, no pets without permission, and no subletting without consent.
Rent is usually your largest housing cost, but it is not the only one. Many leases require a security deposit — money you pay upfront that the landlord holds. If you move out without damage beyond normal wear, you get it back. If you break something or leave the unit dirty, the landlord can use the deposit to pay for repairs. Some apartments also charge a pet deposit if you have animals, and utilities like electricity, water, and internet may be your responsibility or the landlord's, depending on the lease.
What is included in an apartment versus what you pay for separately
Some apartments are furnished — they come with a bed, couch, table, and chairs already inside. Most are unfurnished — you bring your own furniture. Either way, the lease will say what is included. Typically, the landlord provides the appliances that are built in: stove, refrigerator, dishwasher, washer, dryer (if present). You provide everything else: furniture, dishes, bedding, towels, light bulbs.
Utilities vary by lease. Some apartments include water, sewer, and trash in the rent. Others make you pay the utility company directly for electricity, gas, water, and internet. Ask the landlord or property manager before you sign which utilities are included and which you pay for. This can add $100 to $300 per month to your housing cost, so it matters for your budget.
Apartment sizes and layouts
Apartments come in different sizes, described by the number of bedrooms and bathrooms. A studio has no separate bedroom — the main room is both living room and bedroom. A one-bedroom has one separate bedroom plus a living room, kitchen, and bathroom. A two-bedroom has two bedrooms and usually one or two bathrooms. Larger apartments with three or more bedrooms exist but are less common in rental buildings.
The size of the unit is measured in square feet. A studio might be 400 to 600 square feet. A one-bedroom is often 600 to 900 square feet. A two-bedroom ranges from 900 to 1,200 square feet or more. The lease or listing will state the square footage so you know what you are getting. Rent usually increases with size and number of bedrooms.
Apartments versus other housing types
An apartment differs from a condo in one crucial way: ownership. A condo is a unit inside a building that the resident owns outright, like owning a house. The condo owner pays a monthly fee to a homeowners association for building maintenance, but they own the unit itself and can sell it. An apartment renter never owns the unit — they pay rent to use it temporarily.
A house is a standalone structure on its own land. When you rent a house, the landlord owns the entire building and land. When you own a house, you own both. Houses usually have more space and privacy than apartments, but they cost more and require more maintenance responsibility if you own one. Apartments are more affordable and require less upkeep on your part because the landlord handles the building.
A townhouse is a middle ground — a narrow, multi-story unit that shares walls with neighbors but has its own entrance and sometimes a small yard. Townhouses can be rented or owned. They typically cost more than apartments but less than single-family houses.
Why people choose apartments
Apartments are popular because they are usually cheaper than houses in the same area. You do not pay for land, and the landlord spreads maintenance costs across many units. Apartments are also easier to move out of — most leases are one year, so you can leave without selling property. If you do not want to maintain a yard, fix a roof, or handle major repairs, an apartment shifts that burden to the landlord.
Apartments also offer amenities that individual houses do not. Many have a gym, pool, community room, or parking garage included in the rent. You have neighbors nearby, which some people prefer for safety and social reasons. If you are new to an area, renting an apartment lets you try a neighborhood before committing to buying a house there.
What happens when your lease ends
When your lease term is over — usually after one year — you have choices. You can sign a new lease for another year, often at a slightly higher rent. You can ask the landlord to go month-to-month, meaning you pay rent each month with no set end date and can leave with 30 days' notice. Or you can move out.
If you move out, you must return the keys, leave the unit clean and undamaged, and provide the notice period stated in your lease (usually 30 days). The landlord will inspect the unit and return your security deposit, minus any deductions for damage or unpaid rent. Most states require the landlord to return the deposit within 30 to 45 days and provide an itemized list of any deductions.
Frequently Asked Questions
Do I own an apartment if I pay rent for it?
No. Paying rent means you have the right to live there for the lease term, but you do not own the unit or building. The landlord owns it. When your lease ends, you must leave unless you sign a new one. Ownership is different — it means you own the property outright and can sell it or pass it to heirs.
What is the difference between an apartment and a flat?
In the United States, "apartment" and "flat" mean the same thing — a rental unit inside a larger building. "Flat" is more common in the UK and other countries. Both refer to a self-contained living space where you rent from a landlord.
Can a landlord evict me from an apartment?
Yes, but only for specific reasons and following legal steps. Common reasons include not paying rent, breaking lease rules, or the landlord wanting to move into the unit themselves. The landlord must give written notice and follow your state's eviction process, which usually includes a court hearing. You have the right to defend yourself in court.
What happens to my security deposit when I move out?
The landlord inspects the unit and returns your deposit within a set time (usually 30 to 45 days, depending on your state). They can deduct money for damage beyond normal wear and tear, unpaid rent, or cleaning if the unit is left very dirty. They must provide an itemized list of deductions. If they keep money unfairly, you can dispute it in small claims court.
Is it cheaper to rent an apartment or buy a house?
Renting an apartment is usually cheaper upfront and monthly. You do not need a down payment, and rent is often lower than a mortgage payment in the same area. Buying a house requires a down payment (often 3 to 20 percent of the price), closing costs, property taxes, insurance, and maintenance. Over many years, owning can be cheaper, but renting is more affordable short-term and requires less money to start.
