An efficiency apartment is a one-room rental unit with a bedroom, kitchen, and bathroom all in one open or semi-open space

An efficiency apartment, also called a studio or bachelor apartment depending on your region, combines sleeping, living, and cooking areas into a single room. The kitchen is not a separate room — it's usually a counter and appliances along one wall of the main living space. The bathroom is the only fully enclosed room. There's no separate living room, dining room, or bedroom door.

The total square footage typically ranges from 300 to 500 square feet, though this varies by building and location. Because everything is in one room, an efficiency costs less to rent than a one-bedroom apartment in the same neighborhood. The tradeoff is that cooking smells spread through your entire living space, and you have no visual separation between where you sleep and where you eat.

Key Takeaways

  • An efficiency has one main room that serves as bedroom, living room, and kitchen combined, plus a separate bathroom.
  • Efficiency apartments rent for less than one-bedroom units in the same area because they have fewer square feet and fewer rooms.
  • The kitchen is part of the main room rather than a separate enclosed space, so cooking odors and noise affect your entire living area.
  • Some buildings call them studios or bachelor apartments, but the layout is the same: one open room plus a bathroom.

How an efficiency differs from a studio and a one-bedroom

The terms "efficiency" and "studio" are often used interchangeably, and in most rental markets they mean the same thing. Both have one main open room with an attached kitchen and a separate bathroom. Some landlords use "efficiency" for older buildings and "studio" for newer ones, but the layout is identical.

A one-bedroom apartment has a separate bedroom with a door that closes, a distinct living room, and a kitchen that may or may not be fully enclosed. This separation means you can close the bedroom door to sleep while someone else watches television in the living room, and cooking doesn't fill your sleeping space with odors. A one-bedroom typically costs 30 to 50 percent more per month than an efficiency in the same building or neighborhood.

A studio-efficiency hybrid sometimes exists in newer buildings: it has a slightly larger main room and may include a small alcove or partial wall that suggests a separate bedroom area, but there's no door. These rent between a true efficiency and a one-bedroom.

What you actually get in the main room

The single main room in an efficiency contains your bed, seating, dining table (if you have one), and kitchen appliances. The kitchen portion is usually a galley-style counter with a stove, refrigerator, and sink built into one wall or corner. There's rarely a separate dining area — you eat at a small table in the main room or at a counter if one exists.

Storage is limited. Efficiency apartments typically have one closet for clothing and coats, and under-bed storage or a small pantry for food and kitchen items. If you own a lot of furniture or clothing, an efficiency will feel cramped. Many people who live in efficiencies keep only essential furniture: a bed, a small sofa or chair, and a small table.

The bathroom is always separate and fully enclosed. It usually contains a toilet, sink, and shower or tub — the same as any other apartment. Some older efficiency buildings have smaller bathrooms than newer ones.

Rent, utilities, and what's typically included

Efficiency apartments rent for less than one-bedrooms because they have fewer square feet and fewer rooms to maintain. In most cities, an efficiency rents for 60 to 75 percent of what a comparable one-bedroom costs. In expensive markets like New York or San Francisco, the gap can be smaller — sometimes only 20 to 30 percent less. The exact difference depends on the neighborhood, building age, and what amenities are included.

Utilities — heat, water, electricity, and trash — are sometimes included in the rent and sometimes not. Always ask the landlord or property manager which utilities you pay separately. Because an efficiency is smaller, your individual utility costs are usually lower than in a larger unit, even if you pay them yourself.

Parking, internet, and laundry are handled the same way as in any apartment building. Some efficiency buildings include parking; others charge extra or have no parking. Laundry may be in-unit, in a shared basement, or off-site. Ask about these before you sign a lease.

Who typically rents an efficiency apartment

Efficiency apartments attract people in specific situations: young adults starting their first rental, people living alone on a tight budget, and individuals who spend most of their time outside the apartment. Students, service workers, and people in transition often choose efficiencies because the lower rent frees up money for other expenses.

Couples and people with children usually find efficiencies too small. Families need separate bedrooms, and couples often need space to be apart. If you work from home or spend most of your day indoors, an efficiency's lack of separation between living and sleeping areas can become frustrating.

Some people rent efficiencies as a temporary step — while saving for a down payment on a house, while between jobs, or while deciding where to live long-term. Others choose them permanently because the low rent and minimal maintenance suit their lifestyle.

Lease terms and what to check before signing

Efficiency leases follow the same rules as any apartment lease. Most are for 12 months, though some landlords offer shorter terms. Read the lease carefully to understand what utilities you pay, whether there are fees for parking or amenities, and what the landlord's policy is on subletting or early termination.

Before you sign, visit the apartment and check the kitchen appliances, water pressure, heating and cooling, and storage space. Open all cabinets and closets to see what you're actually getting. Ask the landlord or current tenants about noise from neighbors, how quickly maintenance responds, and whether the building has any ongoing issues. In an efficiency, you're living in one room, so problems with noise or temperature control are harder to escape than in a larger unit.

Ask about the move-in costs: first month's rent, last month's rent, and security deposit. Some landlords charge additional fees for pets, parking, or utilities. Get the total amount in writing before you commit.

Frequently Asked Questions

Can I have a roommate in an efficiency apartment?

That depends on the lease and local housing codes. Some leases explicitly prohibit more than one person living in the unit. Others allow roommates but may charge higher rent or require both people to sign the lease. Check your lease or ask the landlord before moving someone in — violating occupancy rules can result in eviction.

Is an efficiency cheaper than renting a room in a shared house?

Usually yes, but it depends on your area. In some cities, a room in a shared house costs less because you're splitting utilities and rent with multiple people. In others, an efficiency is cheaper because you're not paying a landlord's markup on shared spaces. Compare specific listings in your neighborhood to see which option costs less.

Will I be able to cook in an efficiency without the smell spreading everywhere?

Cooking smells will spread through the main room and linger. If you cook frequently or make strong-smelling foods, an efficiency may not be ideal. Using a fan, opening windows, and cooking foods with milder odors helps. If you rarely cook and mostly eat out or use a microwave, this won't be a problem.

What happens if I need more space later?

You can break the lease early if the landlord agrees, though you may lose your security deposit or owe an early termination fee. Most leases allow you to move out when the lease ends without penalty. Start looking for a new apartment a month or two before your lease expires so you have time to find something larger.

Do efficiency apartments have air conditioning?

Some do and some don't — it depends on the building and location. Older buildings in cooler climates often don't have air conditioning. Newer buildings and those in hot climates usually do. Ask the landlord specifically whether the unit has central air, a window unit, or neither before you sign.
