Recovery of past CAM overcharges depends on your specific lease terms, including any audit rights deadlines or ‘binding and conclusive’ provisions, and on applicable state law.

State statute of limitations periods apply to written contracts and range from 3 to 10 years. Your actual lookback window may be shorter based on your lease.

Millage Rate (Mill Rate)

Last updated: April 2026

The tax rate applied to a property's assessed value to determine the annual property tax bill. One mill equals one dollar of tax per $1,000 of assessed value. Understanding millage rates helps tenants verify that the tax amount passed through in CAM is calculated correctly.

Technical Definition

Millage rate is set annually by local taxing authorities (county, city, school district, special districts). Total millage is the sum of all overlapping jurisdictions. Property tax equals assessed value multiplied by total millage rate divided by 1,000. Some jurisdictions apply exemptions (homestead, agricultural) that reduce the effective rate for qualifying properties. Commercial properties rarely qualify for exemptions, making their effective rate the full published millage.

How This Gets Abused

A landlord calculates tax pass-throughs using the prior year's higher millage rate instead of the current year's rate, which was reduced by the county. Tenants overpay because they assume the landlord is using current figures.

Tenant Protection Tip

Look up your building's millage rate on the county tax assessor's website. Multiply it by the assessed value to calculate what the tax bill should be. Compare this against the amount your landlord passes through. Discrepancies indicate an error or overcharge.
