Utility Billing 101: Rate Schedules and Compliance — Getting It Right

Every utility bill your property receives is calculated using a rate schedule — a document published by the utility company that defines exactly how consumption translates to charges. These schedules determine what you pay, and they should determine what you bill residents.

But here's the problem: most operators never look at the rate schedule. They set up their billing system once, use a flat per-gallon or per-kWh rate, and assume it's correct. It usually isn't — because rate schedules are more complex than a single number, and they change more often than operators expect.

This is the final installment of our Utility Billing 101 series. If you've followed along from the beginning, you know the fundamentals. Now let's make sure you're billing at the right price.

What Is a Rate Schedule?

A rate schedule (sometimes called a tariff or rate tariff) is the official pricing document that a utility company files with the state public utility commission (PUC). It defines:

• Base charges — fixed monthly fees regardless of consumption
• Volumetric rates — per-unit charges (per kWh, per gallon, per therm)
• Tiered rates — different prices at different consumption levels
• Seasonal adjustments — higher rates in peak demand months
• Demand charges — charges based on peak consumption during a billing period (common for commercial electric)
• Surcharges and riders — additional fees for infrastructure, environmental compliance, fuel adjustment, etc.

Rate schedules are public documents. Every regulated utility publishes them on their website or makes them available through the state PUC. If you've never read the rate schedule for your properties' utilities, today is the day.

Why Rate Schedules Matter for Billing

When you bill residents for utility consumption, you need to decide what rate to apply. This decision has direct financial and compliance implications:

Billing at the actual rate: You mirror the utility company's rate schedule exactly — tiers, seasonal adjustments, surcharges, and all. This is the most accurate and defensible approach.

Billing at a flat rate: You pick a single per-unit rate (e.g., $0.008 per gallon for water) and apply it uniformly. Simpler to administer but inherently inaccurate — it overcharges some months and undercharges others.

Billing at a blended rate: You calculate an average rate based on historical bills and apply it. Better than a flat rate but still an approximation.

The regulatory trend is clear: states want actual-cost pass-throughs. Colorado's HB 25-1090 prohibits utility pass-throughs that exceed what the utility bills. Maryland's SB 130 explicitly bars submetered charges above actual utility cost. Ohio's HB 173 would cap rates at the standard service offer.

The safest approach — financially and legally — is to bill at the utility's actual rate.

Reading a Rate Schedule: A Practical Example

Let's walk through a real-world water rate structure. Most municipal water utilities use tiered rates:

Plus surcharges:

• Sewer charge: 90% of water consumption × $6.50 per 1,000 gallons
• Infrastructure rider: $2.15/month
• Environmental compliance fee: $0.35 per 1,000 gallons

For a unit consuming 6,500 gallons in a month:

If you had billed this unit at a flat rate of $7.00 per 1,000 gallons (a common approximation), the charge would have been $45.50 for water alone — missing the base charge, the tiered structure, and all surcharges. That's a 48% undercharge.

Common Rate Schedule Errors

Error #1: Using a Flat Rate Instead of Tiered

The problem: Utility rates are almost never flat. Water, electric, and gas all commonly use tiered structures where the per-unit price increases with consumption. Using a single flat rate means low-usage units are overcharged and high-usage units are undercharged.

The fix: Configure your billing system to mirror the utility's tier structure. Any modern billing platform should support multi-tier rate configurations.

Error #2: Missing the Base Charge

The problem: Many operators bill only the volumetric charges (per kWh, per gallon) and forget the fixed monthly base charge that appears on every utility bill. The base charge is a real cost — typically $10-30 per meter per month — and it adds up.

The fix: Include the base charge in your per-unit billing, either as a fixed line item or distributed across units. How you handle it depends on your billing method:

• Submetered: Each unit's bill includes their share of the base charge
• RUBS: The base charge is included in the total bill being allocated

Error #3: Not Updating for Rate Changes

The problem: Utility rates change. Rate increases typically take effect July 1 or January 1 each year, following PUC approval. If you set up your billing rate in 2024 and haven't checked it since, you're likely billing at an outdated rate — which means either undercharging residents or overcharging them (a compliance issue).

The fix: Audit your billing rates against published rate schedules at least twice per year — January and July. Set calendar reminders. Better yet, use a billing platform that tracks rate changes for you.

Error #4: Wrong Rate Classification

The problem: Utility companies have different rate schedules for residential, commercial, industrial, and master-metered customers. Your property may be on a commercial rate (master-metered service) while you're billing residents at a residential rate — or vice versa.

The fix: Verify your rate classification with the utility company. Request a review of your account to confirm you're on the correct rate schedule. If you're master-metered, you should be billing at the rate that matches your utility account — not the published residential rate.

Error #5: Ignoring Surcharges

The problem: Beyond the base charge and volumetric rates, utility bills include surcharges — fuel adjustment, environmental compliance, infrastructure riders, franchise fees. These charges are part of the utility's cost and should be included in what you bill residents.

The fix: Review a utility bill line by line and ensure every charge component is reflected in your billing configuration. Surcharges change frequently — review them at the same cadence as base rates.

Rate Schedules and Compliance

As we've tracked throughout this series and in our Regulatory Shift coverage, the regulatory direction is toward actual-cost, transparent billing. Rate schedule compliance is central to this:

The "No Markup" Trend

Multiple states now require that submetered or allocated utility charges cannot exceed the utility company's actual rate:

• Colorado HB 25-1090: Third-party billing markups capped at 2% or $10
• Maryland SB 130: Prohibits charges above actual utility cost for submetered water
• Ohio HB 173 (pending): Would cap submetered rates at the standard service offer

What this means for operators: If you're billing at a rate higher than what the utility charges you — even unintentionally due to an outdated rate configuration — you may be out of compliance. This is why mirroring the actual rate schedule matters.

Record-Keeping Requirements

States like Virginia (SB 294) require that operators maintain records of how charges are calculated and make them available to residents. Your rate configuration is part of this record. If a resident asks "why did you charge me $8.50 per 1,000 gallons for water?" you need to be able to show the published rate schedule and your billing configuration.

Dispute Defense

When a resident disputes a utility charge, the rate schedule is your primary evidence. If your billing rate matches the utility's published schedule, the dispute is straightforward to resolve — show the math. If your rate doesn't match, you've lost the argument before it starts.

Building Your Rate Schedule Library

For every property in your portfolio, maintain a rate schedule file:

1. Identify every utility provider for each property (water, sewer, electric, gas, trash)
2. Download the current rate schedule from each provider's website
3. Note the effective date — when the current rates took effect
4. Record the rate classification — residential, commercial, master meter, etc.
5. Document all components — base charge, volumetric tiers, seasonal factors, surcharges
6. Set review reminders — check for updates in January and July

Store this in a shared location accessible to both your billing team and your AP team (see Part 6: Accounts Payable). When AP receives a utility invoice, they can verify the charges against the published schedule. When billing generates resident charges, they can verify the rates match.

The Bottom Line

Rate schedules are the foundation of accurate utility billing. If you're billing at the wrong rate — too high, too low, or just outdated — everything downstream is wrong: resident charges, recovery rates, compliance posture, and NOI impact.

The fix is simple: read the rate schedule, configure your billing to match it, and check it twice a year. That's it. No technology upgrade required. No capital expenditure. Just attention to the numbers that drive your billing operation.

The operators who bill accurately bill confidently. And confident billing — transparent, documented, defensible — is what the regulatory environment now demands.
