A common area is any part of a property that is shared rather than rented or owned by one person. In an apartment building, that means lobbies, hallways, stairs, elevators, laundry rooms, parking lots, mail areas and grounds. In a shopping center, it includes parking, walkways and landscaping. In a condominium or planned community, the same idea is usually called the common elements.
Common areas are controlled by the owner or association, not by individual tenants, which is why responsibility for them sits there too.
What counts as a common area
- Circulation: entrances, lobbies, hallways, stairs and elevators
- Shared services: laundry rooms, trash areas, mailrooms and storage
- Outdoor space: parking, sidewalks, courtyards, pools and playgrounds
- Building systems that serve everyone, such as the roof and central boiler
A private balcony or a parking space assigned in the lease is usually not common area, even if it sits next to one.
Who maintains it and who pays
In residential rentals, the landlord maintains common areas and pays for them out of rent. In commercial property, many leases pass these costs to tenants as common area maintenance charges, especially under a triple net lease. In a homeowners or condo association, owners pay for common areas through dues set by the HOA.
Example of a cost share
A hypothetical retail center has 20,000 square feet of leasable space and $60,000 a year in common area costs, or $3 per square foot. A tenant leasing 2,500 square feet pays 12.5% of the total, which is $7,500 a year, usually billed monthly as $625 and reconciled after the year ends.
Safety and liability
Because the owner controls common areas, the owner is usually responsible for injuries caused by hazards they knew about or should have found, such as broken stairs, poor lighting or ice left on a walkway. Regular walk throughs, quick repairs and a record of when problems were reported and fixed are the best protection. Insurance requirements and liability rules vary by state.
Why it matters for landlords
Common areas shape the first impression of a property and are a frequent source of complaints and claims. Put them on a schedule: daily or weekly checks, seasonal tasks such as gutter cleaning and snow removal, and a clear way for tenants to report problems. In TenantLoop, tenants send requests from the portal, and recurring work orders and inspections keep shared spaces on a routine with photos and dates attached.
Related terms
In practice. How the term shows up day to day.
Who is responsible for common areas in an apartment building?
The owner, in nearly every case. Tenants control their own unit, while the landlord keeps shared spaces safe, clean and in good repair.
Do commercial tenants pay for common areas?
Often, yes. Many commercial leases add a share of common area costs to base rent, usually split by square footage. These are called CAM charges.
Can a landlord set rules for common areas?
Yes, within the law. Reasonable rules on hours, guests, noise and use of shared spaces can go in the lease or house rules, as long as they apply equally to everyone.
