Leases and CAM
Are Janitorial Costs Included in CAM Charges?
Who pays for cleaning is written into the lease, often in more detail than either side remembers. Here is how it usually works and what to check.

The short answer
Janitorial costs are included in CAM charges when they cover common areas, such as lobbies, corridors, shared restrooms and elevators, and the lease allows them to be recovered. Cleaning inside a tenant's own premises is different. In full-service office leases, the landlord usually provides it and recovers increases through operating expense pass-throughs, while in triple net retail and industrial leases tenants usually arrange and pay for their own. The lease language, not industry habit, decides each case.
How lease type decides who pays for janitorial
The lease structure sets the default. Multi-tenant office buildings commonly use full-service gross leases, where cleaning is part of the rent and cost increases above a base year are passed through. Retail centers and industrial parks commonly use triple net leases, where tenants pay a share of common area maintenance and look after their own space. Modified gross leases fall in between and vary widely.
| Lease type | Common area cleaning | Cleaning inside the tenant's space |
|---|---|---|
| Full-service gross (office) | Landlord provides; increases over the base year passed through | Landlord provides to a building standard; extras billed to the tenant |
| Modified gross | Usually landlord, recovered as the lease allows | Often the tenant's cost, paid directly or reimbursed |
| Multi-tenant triple net | Recovered as CAM by pro rata share | Tenant arranges and pays |
| Single-tenant triple net | Tenant controls the whole property | Tenant arranges and pays |
What common area maintenance janitorial usually covers
In an office building, common area janitorial covers the spaces every tenant uses. In a retail center or industrial park, CAM cleaning is mostly outdoors: parking lot sweeping, litter pickup, trash enclosure cleaning, walkway pressure washing and, in some centers, public restrooms. Shared waste service also lands here, including the organics and recycling containers California's SB 1383 regulations require businesses to provide.
- Main lobbies, entries and elevator lobbies
- Corridors and multi-tenant restrooms on each floor
- Elevator cabs and stairwells
- Shared amenities such as a tenant lounge or conference center, where the lease includes them
- Day porter service in common areas
- Parking areas, walkways and trash enclosures
Base building versus tenant cleaning in office leases
Office leases often attach a cleaning specification as an exhibit, describing the building-standard service the landlord provides inside each suite, such as nightly trash removal, vacuuming, dusting and restroom cleaning on business days. Anything beyond that standard, such as a full kitchen, a data room, extra frequencies or after-hours cleaning, is typically billed to the tenant as an excess service.
Many office leases also gross up variable operating expenses, janitorial being the classic example, to an assumed occupancy level stated in the lease. That keeps tenants from paying a distorted share when the building is partly vacant, and stops the base year from being set artificially low. Read the gross-up clause before comparing year-over-year charges.

Which janitorial costs should stay out of CAM charges
Tenants and their advisers commonly negotiate exclusions so that the common pool pays only for work that benefits everyone. The items below are frequent points of discussion; the lease language, read with counsel, decides what actually applies to a particular property.
- Cleaning of another tenant's premises or its above-standard requests
- Construction cleanup for tenant improvements
- Cleaning of the landlord's leasing or management office
- Replacement of carpet or flooring treated as a capital item
- Costs reimbursed by insurance or by a responsible party
- Administrative fees beyond the amount or cap the lease allows
How tenants and property managers can check the numbers
The annual CAM reconciliation is the moment to look. A tenant with audit rights can usually request the janitorial contract, invoices and the allocation method within a window set by the lease. Property managers make reconciliation far easier when the cleaning contract itself separates common areas, tenant premises and periodic work into distinct lines, because each cost can then be allocated without estimates. A blended single monthly price is the most common source of reconciliation disputes.
How EBS sets up scopes for clean allocation
Clear CAM allocations start with a clear scope. EBS can organize tasks by area, frequency and service window, so lobbies, corridors and shared restrooms are priced apart from tenant suites, and periodic work such as floor refinishing or day porter hours sits on its own lines. Supervisors keep in touch with the property team, and routine inspections give a documented record of the work charged to each pool.

Request a walkthroughAll questionsWho pays for janitorial in a triple net lease?
Usually the tenant, twice over: it arranges and pays for cleaning inside its own premises, and it pays a pro rata share of common area cleaning through CAM. The exact split depends on the lease, so check the operating expense and maintenance sections rather than assuming.
Can a landlord add a management fee to janitorial costs?
Often, if the lease allows an administrative or management fee on operating expenses or CAM. The amount, any cap and whether it can be charged on top of a separate management fee are negotiated lease terms. Tenants should confirm the fee is calculated the way the lease says.
Are day porter costs part of CAM?
When the porter serves common areas and the lease includes cleaning services in recoverable expenses, usually yes. Porter time spent in a single tenant's space is a different matter and should be billed to that tenant, which is easier when the porter keeps a simple log of rounds.
Can a tenant hire its own cleaning company?
It depends on the lease and the building. Many multi-tenant office buildings require the building's contractor for security and key control, while allowing tenant vendors for specialty work with approval and proof of insurance. In triple net properties, tenants usually choose their own vendor.
