The year changed. The percent on the sheet did not. You tap the faded 7.2% line printed on the commercial lease reconciliation sheet sitting in front of you, your pen hovering over the line item for common area maintenance charges. The 2024 occupancy update you pulled up on your phone next to the paper confirms three new tenants moved into the building in the fourth quarter of 2023, which should lower your pro rata share of operating costs by nearly 2 percentage points, but the reconciliation document makes no mention of that shift. You lean back in your chair for a second, squinting to make sure you didn’t misread the year printed at the top of the page, and confirm it is indeed marked for 2024, not 2023.
What this 2024 CAM reconciliation page lists
This document lays out the full sum of common area maintenance (CAM) costs your landlord incurred across the building over the 2024 calendar year, including landscaping, parking lot repairs, lobby cleaning, building insurance, and property management fees. It first lists the total annual CAM spend for the entire property, then applies your pro rata share to calculate your total annual CAM obligation, subtracts the monthly pre-payments you made throughout the year, and ends with a line listing the remaining balance you are expected to pay within 30 days. Every line item matches the cost categories outlined in your lease, and you don’t spot any obvious inflated charges for repairs or services you didn’t agree to, but the core error sits in the pro rata share used to calculate your portion of the total cost. The page lists no footnote, addendum, or explanation for why the 2023 share is being used for the 2024 calculations, nor does it reference the occupancy adjustment clause written into your original lease agreement. You flip the page over to check for any fine print on the back, and find nothing but a generic return address for the property management team.
The side-by-side pro rata share comparison you run
You work through the comparison step by step to confirm your initial suspicion of an error, taking notes directly in the margin of the reconciliation sheet as you go:
- Pull up the executed lease addendum you signed when you moved into the space, which explicitly ties your pro rata share to annual building occupancy rates, with a required adjustment every January 1 based on total occupied square footage as of December 31 of the prior year.
- Cross-reference the 2023 year-end building occupancy report your property manager emailed you on January 4, 2024, which notes the building hit 92% total occupancy as of December 31, 2023, with three new 5-year tenant leases signed for the ground-floor and third-floor suites the prior quarter.
- Calculate your updated 2024 pro rata share using the formula laid out in your lease: divide your total rented square footage (2,160) by total occupied building square footage (38,700) to get a 5.58% share, which rounds up to 5.6% per the lease’s standard rounding guidelines for share calculations.
- Recalculate your total 2024 CAM obligation using the total building CAM costs listed on the reconciliation page ($1,242,000) multiplied by the updated 5.6% share to get $69,552, compared to the $89,424 the reconciliation page lists using the old 2023 share.
Illustrative example: The gap between the overstated share on the reconciliation and your actual 2024 share comes out to $19,872 in overcharged CAM costs, before accounting for the $1,287 balance the page claims you owe.
You jot the adjusted total in the margin of the paper in blue ink, circling the 7.2% share on the page and drawing an arrow to your calculation, so you don’t have to redo the math later. You cross-reference the occupancy report a second time to confirm no tenants moved out in the first quarter of 2024 that would adjust the share back up, and you find no records of occupancy shifts that would justify keeping the 2023 rate in place. You cross-check the math using the pro rata share calculator you accessed through Lease Jacket earlier this month, and the number matches the calculation you just did by hand, confirming you didn’t make an arithmetic error when running the numbers yourself. You also note that the property management team used the same incorrect share for your monthly 2024 pre-payments, so the overcharge was spread evenly across all 12 months of the year, rather than being a one-time mistake on the final reconciliation.
When you retrieve this sheet from your file folder next month
You slide the sheet into the front of your lease file folder when you stand up from the table, tucking the printed copy of the occupancy report and lease addendum behind it so all relevant documents are in one place for your upcoming call. When you pull the sheet out again next month, right before your scheduled call with your property manager to discuss the discrepancy, you’ll flip straight to the margin where you wrote your calculation to walk them through the error step by step. You’ll have the digital copies of the occupancy report and lease addendum pulled up on your laptop to reference if they ask for proof of the occupancy shift or the adjustment clause, and you’ll ask for a revised reconciliation document that uses the correct 5.6% share to calculate the 2024 CAM obligation. You don’t go into the conversation assuming the error was intentional; administrative oversights are common for property management teams that oversee dozens of buildings and hundreds of tenant leases, and you frame the ask as a simple correction to align the document with the terms you both agreed to. If the property manager pushes back on the occupancy data, you can request a full 2024 tenant roster and square footage breakdown to cross-check occupied space, which your lease entitles you to access within 10 business days of your request. You also plan to ask for confirmation that the 2025 monthly CAM pre-payment amounts will use the updated 5.6% share, to avoid the same administrative error leading to overpayments again next year. Once you receive the revised reconciliation, you’ll attach it to the original copy in your file folder, so you have a record of both the initial error and the correction for future reference when you receive next year’s reconciliation. You don’t need to take further action unless the property management team refuses to adjust the document, and you can follow the formal dispute process laid out in your lease if that happens, without escalating to more aggressive steps immediately. The entire correction process takes less than 15 minutes of your time once you get the property manager on the phone, and the revised reconciliation arrives in your inbox three business days after your call, with confirmation that the overcharged amount will be applied as a credit to your next three months of rent. You jot the credit confirmation on the original sheet before filing it away again, so you can cross-check the rent charges over the next quarter to make sure the credit is applied correctly.
