The direct answer
Owner-paid utilities generally reduce property NOI when they are operating expenses, while utility reimbursements can offset part of that burden when tenants repay the owner under the lease or billing structure. The key is to show gross utility expense and reimbursement income consistently rather than netting them in a way that hides cost trends.
Identify who is contractually responsible
Review the lease and billing arrangement for electricity, water, gas, trash and other services. Some costs can be directly metered to tenants, while others remain owner obligations with partial reimbursement.

Keep expense and reimbursement logic consistent
If the owner pays $30,000 of utilities and receives $20,000 of tenant reimbursement, the economic burden is $10,000 before considering collection loss or administrative cost. Reporting conventions can differ, so define the method used in NOI.
Stress utility inflation and recovery gaps
Owner-paid utilities can rise faster than rent or reimbursement schedules. Model recovery percentage and collection performance instead of assuming every expense increase is fully passed through.
Worked example
A property pays $5,000 per month for water and recovers $3,500 through tenant billing. The unrecovered $1,500 monthly burden reduces property economics unless another revenue source offsets it.

Common mistakes and limitations
Do not assume reimbursement eliminates utility risk. Usage, billing caps, vacancies and nonpayment can leave part of the cost with the owner.
Does not determine lease legality, fees outside modeled concessions or renewal economics.
Frequently asked questions
Do owner-paid utilities reduce NOI?
Generally they reduce NOI when treated as operating expenses, subject to the property’s reporting convention.
Should reimbursements be shown as income or netted against expenses?
Either presentation can be used in practice, but the underwriting should be consistent and transparent so the recovery gap is visible.
