How Common Area Maintenance Charges Work in the Philippines
Every tenant in a Philippine commercial building pays for space they cannot occupy. The lobby, the lifts, the corridors, the restrooms, the loading bay, the security desk, the landscaping, and the building management office all cost money to operate, and that cost is recovered from the tenants who benefit from them. In the Philippines this recovery is called the Common Usage Service Area charge, universally abbreviated to CUSA and known internationally as common area maintenance, or CAM.
CUSA is quoted separately from rent, applied per square meter per month, and treated by most tenants as a fixed and uninteresting line item. It is neither. In a Grade A Metro Manila office building, CUSA commonly runs between ₱180 and ₱215 per square meter per month, on a 500 square meter requirement, ₱90,000 to ₱107,500 monthly, or well over a million pesos a year. Whether that figure is fixed, escalating, or reconciled against actual expenditure determines who carries the risk of rising building costs, and the lease frequently answers that question in a single clause that nobody reads closely.
What CUSA Actually Covers
The charge funds the operation of everything outside the tenant's demised premises. In a standard Metro Manila office building, this typically includes the cleaning and maintenance of lobbies, corridors, lifts, stairwells, and shared restrooms; security personnel and systems; reception and concierge services; landscaping and external maintenance; electricity and water serving common areas; maintenance of lifts, fire safety systems, generators, and building services; pest control and waste management; and the salaries of the building management team.
What CUSA does not cover is equally important. It does not cover the tenant's own electricity consumption, which is separately metered. It does not cover air conditioning within the demised premises, which in most Philippine buildings is charged separately either by meter or at a rate per square meter. It does not cover the tenant's own cleaning, security, or maintenance within its space. And it does not cover capital expenditure, the replacement of a lift or the renewal of a façade is an owner's cost, though poorly drafted leases sometimes attempt to blur this line.
Coverage varies between buildings, and the variation is material. Two buildings quoting ₱200 per square meter may include different items, and a comparison of headline CUSA rates without a comparison of inclusions tells a tenant very little.
How the Charge Is Computed
The standard method allocates the building's total common area operating cost among tenants in proportion to leased area. A tenant occupying 500 square metres in a building with 20,000 square metres of leasable area carries 2.5 per cent of the recoverable cost.
Two structures then follow from this base calculation, and the difference between them is the single most important thing a tenant should establish before signing.
Under a fixed CUSA, the landlord quotes a rate per square meter and that rate applies for the term or for a defined period. The tenant has certainty. The landlord carries the risk that operating costs rise faster than the fixed rate, and is correspondingly incentivized to run the building efficiently.
Under a reconciled CUSA, the landlord bills an estimated rate through the year and reconciles at year end against actual expenditure, issuing a balancing charge or credit. The tenant carries genuine cost inflation risk. This is the structure that makes a lease functionally a net lease regardless of what the document calls itself.
A third variation applies an annual escalation to CUSA, commonly at the same rate as rent escalation, which is typically around five per cent in the Metro Manila market. This sits between the two: the tenant knows the schedule but pays more each year regardless of whether costs rose.
Tenants signing a reconciled arrangement should negotiate two protections. The first is a cap on the annual increase, so that the reconciliation cannot produce an unbudgeted step change. The second is an audit right, permitting the tenant or its representative to inspect the supporting expenditure records on reasonable notice. Landlords rarely refuse an audit right outright, and tenants rarely ask for one.
The Extended Hours Premium
A feature of the Philippine market that catches foreign occupiers in particular is the differential treatment of extended operating hours.
Standard building hours in a Metro Manila office are commonly weekdays from around eight in the morning to six in the evening, with reduced Saturday coverage. Buildings serving the information technology and business process management sector operate around the clock, and the additional security, cleaning, utilities, and management that twenty-four-hour operation requires is charged at a higher CUSA rate.
For a business running shifts, this is not an optional extra. Listings advertising a CUSA rate of ₱180 per square meter for standard hours may carry a materially higher rate for continuous operation, and the difference across a large floor plate over a five-year term is substantial. Any occupier whose business model requires operation outside standard hours should establish the applicable rate before comparing buildings, not after.
The same principle applies to air conditioning. After-hours cooling is almost universally charged separately, either metered or at a fixed hourly rate per zone, and a business operating a night shift will pay it every night.
How Malls Differ From Offices
Retail leases in Philippine shopping centres apply the same underlying logic with several additional layers that materially change the economics.
Longer operating hours are the first. A mall trading from ten in the morning until nine or ten at night, seven days a week, incurs proportionally higher common area operating costs than an office building running weekday business hours, and retail CUSA rates reflect this.
Air conditioning as a common area cost is the second. In most malls the entire trading environment is conditioned as common space rather than metered to individual units, which shifts a significant cost into the common charge.
Marketing and promotional funds are the third and are frequently mistaken for CUSA. Mall operators commonly levy a separate charge funding center-wide advertising, seasonal activation, and events. This is a distinct obligation from common area maintenance and should be quoted, budgeted, and negotiated separately.
Percentage rent is the fourth. Many Philippine mall leases combine a base rent with a percentage of the tenant's gross sales above a defined threshold. This structure interacts with CUSA in a way tenants should model carefully: the total occupancy cost ratio, all rent, CUSA, marketing contributions, and utilities as a percentage of sales, is the figure retailers actually manage to, and a favorable base rent paired with heavy ancillary charges can produce a worse outcome than the reverse.
Location within the center produces significant variation in the base rate. Ground floor frontage near an anchor tenant or a primary entrance commands multiples of an upper-floor or peripheral location, and CUSA allocation methods in some center weight for location as well as area.
Industrial and Warehouse Treatment
Industrial estates and logistics parks apply a different vocabulary but the same principle. Charges here are frequently described as estate dues or association dues rather than CUSA, and cover perimeter security, internal road maintenance, drainage, common lighting, and estate administration.
Rates are generally lower than office CUSA on a per square meter basis, reflecting the more limited common infrastructure. Within PEZA-registered economic zones, locators may face zone administration charges in addition to estate dues, and these should be established during site selection rather than discovered after the lease is signed.
Questions to Settle Before Signing
A tenant evaluating commercial space should obtain written answers to the following before comparing buildings on price.
What specific services does the quoted CUSA include, and which building costs sit outside it? Is the rate fixed for the term, subject to a defined escalation, or reconciled against actual expenditure? If reconciled, is there a cap on the annual increase, and does the tenant have an audit right? What is the rate for operation outside standard building hours, and what are the standard hours? How is air conditioning charged, and what is the after-hours rate? Is the tenant's proportionate share calculated on leasable area or gross floor area, and is the building's total leasable area disclosed? Are there separate charges for marketing, estate administration, or association dues? And is CUSA subject to value-added tax, and does the building's PEZA accreditation status alter the treatment for a qualifying locator?
The last of these matters more than it appears. Rent and dues paid by a qualifying PEZA-registered enterprise in an accredited building receive different VAT treatment from those paid by an ordinary commercial tenant, and on a large requirement the twelve per cent difference is not marginal.
For Landlords and Investors
From the ownership side, CUSA is a cost-recovery mechanism rather than a profit center, and treating it as the latter is a short-term strategy with predictable consequences. Tenants compare total occupancy cost across buildings, and a competitive base rent paired with an inflated common charge is transparent to any occupier running a proper comparison.
The more durable approach is operational efficiency. A building that delivers comparable service at a lower CUSA rate has a genuine leasing advantage, particularly in a market where prime and Grade A vacancy has been running near eighteen per cent and tenants have real choice. Efficient plant, sensible energy management, and competent building management reduce the recoverable cost and improve the building's competitive position simultaneously.
For investors, the recovery structure is a valuation input. A building where CUSA is fully recovered from tenants under a reconciled arrangement produces a cleaner net operating income than one where the landlord absorbs cost inflation under fixed charges. That difference should appear in the underwriting model rather than in a footnote.
Common area charges are where a meaningful share of occupancy cost hides, and they are almost never the reason a tenant chooses a building. Comparing total occupancy cost properly, rent, CUSA, air conditioning, parking, and tax treatment together, is straightforward when the terms are visible before you enquire.
