How to Review San Francisco Apartment Operating Expenses

Reviewing San Francisco apartment operating expenses means looking beyond the annual profit and loss statement. Owners need to compare costs with similar buildings, examine the work behind recurring charges, and establish how much those expenses take from net operating income. A low expense total can be just as misleading as a high one.

Key Takeaways

• Look at invoices and maintenance records alongside the financial statements.
• Compare buildings with similar systems, staffing needs, and utility arrangements.
• Recurring repair bills may be the early warning of a major replacement.
• Capital projects belong in a separate plan, even when they involve equipment that regularly needs repairs.
• Expense changes affect NOI and, potentially, the financial ratios lenders use.

What the Expense Statement Doesn't Tell You

A building can have a respectable operating statement and still be spending money badly.

Take an older apartment property where plumbing expenses have been unusually low for two years. That looks encouraging until the maintenance records show tenants reporting slow drains, intermittent leaks, and water pressure problems. Several jobs remain open. The owner hasn't saved money through efficient maintenance. Much of the work simply hasn't happened.

The opposite can be true. A building with higher repair expenses may have dealt with longstanding problems that would otherwise produce repeated service calls.

A multifamily operating expense review starts by finding out what the money bought. Annual statements help establish the totals, but invoices, service agreements, inspection reports, and work orders explain them.

The classification question matters here as well. Ordinary repairs generally fall under operating expenses, while major improvements and replacements may need capital treatment. A new roof and a small roof repair shouldn't automatically appear in the same category.

For operating analysis, net operating income (NOI) means property revenue less operating expenses, before financing costs and other excluded items. Poor expense classification makes that number harder to interpret.

Maintenance: Follow the Work Orders

Maintenance budgets tend to receive attention when something breaks, or the annual total exceeds expectations. By then, an owner may have missed months of warning signs.

Say the same drain line has been cleared four times. Each job was completed and invoiced correctly. Yet the problem returned.

The invoices may be perfectly fair. Clearing the same line a fourth time, instead of finding out why it keeps blocking, is the questionable decision.

A camera inspection could reveal damaged pipework that needs replacement. Alternatively, the inspections might show that continued maintenance remains appropriate. The owner needs that information before committing to either course.

A rental property expense audit starts by grouping repair records by system and location. Plumbing, heating, electrical work, roof leaks, and common-area repairs should be examined over several years, where records permit.

Calculate annual maintenance spending per unit, then distinguish scheduled servicing from emergencies. Keep major replacements separate. An older building will naturally require more attention than a recently renovated one, so the comparison needs to account for condition.

The question isn't whether maintenance can be made cheaper. It's whether the work being paid for is actually resolving the problem.

Water Bills: Check the Usage Before Questioning the Rate

Water and sewer costs are easy to overlook because bills arrive regularly and tend to be paid without much discussion. The interesting part is often buried in the consumption figures.

If occupancy hasn't changed but water use has climbed, there may be a running toilet, a leaking supply line, or another problem nobody has reported. In a master-metered building, even a fairly small leak can remain unnoticed.

Compare consumption across billing periods. Look for changes that don't correspond with occupancy or seasonal use.

San Francisco's Public Utilities Commission maintains its 2026–2027 water and sewer rate schedules. The utility's rates changed effective July 1, 2026, so higher bills shouldn't automatically be attributed to greater consumption.

Gas and electricity deserve the same attention. A shared laundry room, exterior lighting, ventilation, or old heating equipment can add considerable operating costs over time.

Check the meters, the equipment being supplied, and the hours of operation. Replacing inefficient equipment might eventually make sense, but the consumption records should support the decision.

An unexplained increase in usage is worth investigating before it becomes another accepted budget item.

Insurance: Compare the Policy, Not Just the Premium

Owners generally notice insurance when the renewal quote arrives.

Sometimes the premium has increased sharply. Sometimes the quoted amount looks reasonable, but the deductible is higher, or the coverage has changed. Either situation deserves a closer look.

A broker needs accurate information about the building's roof, electrical systems, plumbing, claims history, and completed improvements. Incomplete records can make it harder to assess the available coverage.

The California Department of Insurance provides guidance on commercial insurance terms and coverage considerations.

Keep the previous and proposed policies side by side. Compare exclusions, limits, deductibles, and insured risks.

A cheaper policy doesn't necessarily represent a saving if it shifts substantial costs back to the owner when a claim occurs.

From an NOI perspective, premiums are a recurring expense. Coverage gaps, however, may create financial exposure that doesn't appear on the income statement at all.

Vendor Costs: The Contract Matters More Than the Invoice Total

A contractor's invoice may look excessive until somebody checks the actual work.

One cleaning contract includes waste-bin areas, entryways, stairwells, and periodic deep cleaning. Another covers only the common corridors. Comparing the monthly prices tells the owner very little.

Start with the scope. Look at how often services are provided, which materials are included, and how additional work gets approved.

This applies to landscaping, pest control, janitorial services, elevator maintenance, and routine mechanical servicing.

Longstanding contractors can be valuable. They know the building and often understand problems that would take a new provider time to investigate. Still, an owner should know when contracts were last reviewed and whether the pricing reflects the work being delivered.

Repeated extras deserve particular attention. If a contractor regularly charges for tasks supposedly covered by the agreement, the problem may be the contract rather than the contractor.

The same principle applies to larger jobs, although capital projects require a more detailed bidding process. Those decisions belong in a separate capital expenditure review.

Payroll and Resident-Manager Costs

Staffing expenses can be understated when owners use informal arrangements or fail to account for the full cost of having someone available on-site.

California Title 25, Section 42 generally requires a manager, caretaker, or other responsible person to reside at an apartment building with 16 or more units if the owner does not live there. The requirement affects more than the payroll line.

An owner needs to understand the person's duties, hours worked, compensation, housing arrangement, and any relief coverage. The fact that somebody lives in the building doesn't settle the employment questions.

California's Wage Order 5 sets relevant employment standards, including restrictions on lodging credits. Applying a housing credit without the necessary written agreement and compliant calculations may create a wage liability.

When reviewing the budget, include the actual cost of a lawful staffing arrangement. A figure copied from the seller's records may omit expenses the next owner will have to meet.

Management Fees: Read the Agreement

Management fees are another area where the percentage alone can be misleading.

One agreement may include monthly reporting, routine inspections, contractor coordination, and tenant communications. Another may charge separately for some of those tasks.

Examine the contract alongside a sample of monthly statements.

Look for leasing charges, project administration fees, additional inspections, accounting work, and other services outside the base agreement.

An owner-managed property requires particular care during review. The seller may have performed considerable work without recording its cost, leaving the financial statements with an unrealistically small management expense.

The correct comparison is the cost of the services the property actually needs, including items billed separately.

Benchmarking Without Misreading the Numbers

A useful comparison starts with the building, not an industry average.

Two properties with 20 units can have very different expenses. One may have individual utility meters and recently replaced equipment. The other might have shared heating, old plumbing, and an elevator. The second property will require a different operating budget.

Apartment expense benchmarking in San Francisco works only against buildings of reasonably similar construction, age, condition, unit count, metering, and service responsibilities.

Maintenance costs can be expressed per unit per year. Utility consumption can be compared per occupied unit. Insurance may be examined per unit, provided differences in coverage are also considered.

The apartment building expense ratio, calculated by dividing operating expenses by effective gross income, provides a broad additional check. It can be distorted by differences in rents, accounting, and property condition, so it shouldn't be used by itself to judge performance.

High Is Not the Same as Wrong

An expense above the comparison group's average may be justified by the building's age, condition, or service requirements. Benchmarking tells an owner where to look. It does not establish that the spending was unnecessary.

Expense Review Matrix

Category	What to benchmark	Red flag	NOI / DSCR consequence
Maintenance and repairs	Cost per unit; planned versus emergency work	Repeated repairs to the same system	Higher opex reduces NOI and may indicate future capital spending
Water and sewer	Consumption per occupied unit; tariff changes	Rising consumption with stable occupancy	Avoidable consumption reduces NOI
Gas and electricity	Common-area load and seasonal use	Unexplained increases in usage	Recurring utility expense lowers NOI
Insurance	Premium, coverage, deductible, claims history	Large renewal increase or reduced coverage	Higher premiums reduce NOI; coverage changes affect financial risk
Vendor and contractor services	Comparable scope and contract price	Repeated extras or unclear charges	Excess recurring costs reduce NOI
Payroll and resident manager	Staffing duties, wages, housing arrangement	Incomplete records or unsupported lodging credit	Expense increases and potential employment liability
Management fees	Services included and additional charges	Billing that appears inconsistent with the agreement	Additional fees reduce NOI
Operating versus capital expenses	Consistent classification	Routine repairs capitalized or replacements treated as ordinary repairs	Distorted NOI and misleading capital forecasts

Expensive Building or Expensive Way of Running It?

When an expense is higher than expected, the reason isn't always obvious.

A property might genuinely need more work because its systems are older. In other cases, the owner is paying too much for a service, or small jobs are being handled repeatedly instead of being resolved properly. These are different problems.

A competitive quote may address excessive vendor pricing. A water-use investigation might uncover waste. Repeated emergency plumbing calls could justify examining the condition of the pipes.

Trying to reduce apartment operating costs by simply cutting maintenance allowances is risky. Work that is postponed doesn't necessarily disappear from the owner's financial obligations.

The useful savings come from identifying spending that serves no continuing purpose, costs more than necessary, or results from problems that haven't been properly addressed.

Owners also need to know when an expense cannot reasonably be reduced. Required staffing, safety repairs, and essential building services should not be treated as discretionary simply because they affect the budget.

What Expense Control Does to NOI and Lending Ratios

The lender ultimately sees the financial result, not the story behind every invoice. Consider a simplified example. A building collects $500,000 annually in effective gross income and incurs $200,000 in operating expenses. Its NOI is $300,000.

Suppose the owner identifies $10,000 in genuine recurring savings through revised service contracts and corrected utility consumption.

With income and other costs unchanged, NOI rises to $310,000.

If annual debt service is $240,000, the debt service coverage ratio moves from 1.25x to approximately 1.29x.

These figures are illustrative. Actual savings, building performance, and lender calculations vary.

DSCR measures the relationship between income available for debt service and required debt payments. Debt yield compares NOI with the loan amount. Both may influence lender underwriting, although requirements depend on the loan and institution.

A recurring expense reduction can improve those measures. It doesn't guarantee a particular lending outcome or property valuation.

And a lower operating budget is not necessarily an improvement if the owner has deferred necessary repairs. Lenders may examine that exposure separately.

The companion article on DSCR, debt yield, and LTV covers these calculations in detail.

For prospective buyers, the same expense analysis belongs in the acquisition review. Our article on underwriting an SF multifamily acquisition examines why seller expenses frequently need adjustment before they can be used in a forward-looking model.
