Buildium is a property management platform primarily designed for residential properties but used by some small commercial landlords, particularly in mixed-use buildings and small strip retail. Its CAM reconciliation capabilities are basic compared to commercial-focused platforms. Statements are minimal, often covering just a few expense categories with annual totals, and lack much of the detail that commercial tenants need to verify charges.

Free CAM audit → Find My OverchargesUnderstanding what each field means on your Buildium CAM statement is the first step to verifying the charges. Below is a plain-language breakdown of every significant field.
| Field | What It Means |
|---|---|
| Category | A broad expense label covering a group of related costs. Buildium's commercial CAM statements typically show 5 to 8 categories rather than itemized GL line items. |
| Amount | The total annual expenses charged to that category. No sub-items, vendor names, or invoice dates are included on the face of the statement. |
| Your Portion | Your allocated share of the category amount. The pro-rata percentage used to calculate this is not shown unless the landlord has customized the report to include it. |
| Property Management Fee | A single dollar amount for the management fee, typically labeled "Property Management Fee" or just "Management." The fee calculation basis is not disclosed on the statement. |
| Repairs and Maintenance | All repair and maintenance costs grouped into a single category. Capital expenditures can be included here without distinction because Buildium does not enforce a capital vs. operating expense classification at the report level. |
These warning signs are specific to how Buildium structures its CAM output. If you see any of these on your statement, request the supporting documentation before paying the reconciliation balance.
Residential-oriented fields applied to a commercial statement
Buildium's default report templates were designed for residential tenants. Some commercial Buildium statements include fields irrelevant to commercial leases or omit commercial-specific fields like pro-rata share percentage and denominator. If your statement is missing standard commercial CAM fields, request a supplemental breakdown.
Very limited category detail on a multi-tenant commercial property
A commercial property with multiple systems and service contracts should generate more than 5 to 6 expense categories. If your Buildium statement shows only a handful of categories with large totals and no breakdown, you are not seeing the full picture of what is being charged to the CAM pool.
Pro-rata percentage absent from the statement
Buildium's basic commercial template often shows only your allocated dollar amount without the percentage or denominator. An incorrect denominator can inflate your share, and without the percentage on the statement, you cannot detect it without requesting additional documentation.
No prior-year comparison or budget reference
Buildium commercial CAM statements typically show only current-year figures with no budget or prior-year comparison. A significant year-over-year increase in any category is invisible without retaining prior statements for comparison.

Need to extract lease terms before your audit?
A CAM audit is only as accurate as your lease data. lextract.io extracts 126 structured fields from any commercial lease PDF: CAM definitions, pro-rata share, caps, base year, and audit rights. So you have the exact terms your landlord is supposed to follow.
Go to lextract.ioThese overcharges occur frequently in CAM statements generated by Buildium. Each is tied to a specific feature of how the platform structures its reporting or how landlords configure it.
Capital repairs included in the Repairs and Maintenance category
Buildium does not enforce a distinction between operating repairs and capital expenditures at the reporting level. A $30,000 roof repair that extends the roof's useful life can appear as a routine Repairs category total alongside $500 plumbing fixes. Request invoices for any Repairs total that appears disproportionately large.
Management fee calculated on gross income rather than CAM expenses
Some Buildium configurations default to calculating the management fee as a percentage of gross rental income rather than operating expenses. If your lease defines the management fee as a percentage of CAM expenses or controllable CAM, a fee calculated on gross income can be substantially higher than what the lease permits.
Insurance category includes non-building policies
In a Buildium commercial statement, the Insurance category total may include renter's insurance tracking fees, management E&O coverage, or umbrella policies for the property management company. These are not building operating expenses and should not be in the CAM pool.
Pro-rata denominator includes residential units, diluting the commercial share incorrectly
In mixed-use buildings managed through Buildium, the CAM denominator may include residential square footage alongside commercial. If residential tenants are not contributing to the same CAM pool, including their space in the denominator is actually favorable to commercial tenants. But if the denominator is being manipulated in reverse (excluding large units), it can inflate the commercial share.
