Bill Calculation Service

Tenant bill calculation for mobile home park owners

Stop calculating tenant bills by hand

If your mobile home park is master metered and you sub-meter your tenants, you are responsible for turning raw meter reads into an accurate bill for every space — at the correct rate schedule, with the correct baseline allowance, and with every discount your tenants qualify for applied.

Our Bill Calculation Service does that work for you. You enroll your park once, then submit your tenants' starting and ending meter reads each billing period. We return a calculated bill for every tenant, ready to deliver.

The service covers electric, gas and water, and works whether you deliver the finished bills yourself or have us print, mail and email them for you.

Who the service is for

To use the Bill Calculation Service, your park should:

  • Be served by a master meter from your electric, gas or water utility
  • Have sub-meters installed at each space, or be in the process of installing them
  • Be able to read tenant meters accurately, or have us read them for you
  • Provide accurate usage, discount and occupancy information each period
  • Have a valid email address for receiving calculated bills and invoices

Not sure whether your park qualifies? Send us your utility bill and we will tell you.

What you get back

For every tenant, every billing period:

  • A finished bill showing starting read, ending read, usage and amount due
  • The rate schedule and baseline territory used in the calculation
  • Tiered usage broken out so tenants can see how they were charged
  • Any discounts, credits or refunds applied line by line
  • A park-level summary reconciling tenant billings against your master meter bill

How It Works

1
Enroll Your Park

Enter each space, whether it is all-electric, and any medical baseline or low-income discount that applies to the household.

3
Submit Meter Reads

Enter starting and ending reads through the secure portal, upload a spreadsheet, or let our automated meters report reads for you.

4
We Calculate & Return

Calculated bills are returned within two business days — ready for you to deliver, or delivered by us via email and mail.

What we calculate for you

Sub-metered tenant bills are not a simple rate times usage. Our calculations account for:

  • Baseline allowances by territory, season and end use, including all-electric spaces
  • Tiered rates applied in the correct order as usage climbs through each tier
  • CARE and FERA low-income discounts for qualifying households
  • Medical baseline allowances for tenants with documented medical needs
  • Elevation-adjusted therms, converting metered gas volume using your park's altitude
  • Seasonal rate changes and mid-period rate changes, prorated across the billing period
  • Move-in and move-out prorations, plus vacant space handling
  • Commission-ordered refunds and credits, allocated across your tenants

Frequently Asked Questions

You can submit starting and ending meter reads for your tenants at any time, as long as the tenant billing period does not exceed 33 days. Most owners submit once a month on a fixed schedule, which keeps tenant bills predictable and makes reconciliation against your master meter bill straightforward.

Submit two requests: one bill covering zero to 33 days, and a second bill covering day 34 through the ending read date. This keeps baseline allowances, which are granted on a daily basis, correct for each tenant.

The service is priced as a flat fee per tenant bill calculated. Additional utilities may be added for an incremental fee. If you discover a mistake after submitting, you can correct it and resubmit at the same per-bill fee for each bill that must be recalculated. We invoice monthly.

During enrollment you provide specific data about your park, including the property address, baseline territory and elevation. You then enter each tenant's information — whether the space is all-electric, any medical baseline or low-income discount, and the starting and ending meter reads. From that information we calculate each bill using the residential rate schedule your serving utility applies to sub-metered mobile home park tenants, including the correct baseline quantity and tier structure.

The heat content of natural gas depends on the pressure at which it is delivered, and that pressure depends on the altitude at which it is supplied to your property. We need your park's elevation to convert metered gas volume into billable therms correctly. You can determine your elevation from topographic maps, county records or your property deed — and we can confirm it with you during enrollment.

Email us at contactus@americansubmetering.com and a member of our billing team will walk you through it. Send along a recent copy of your master meter utility bill and we can pre-fill most of your park's enrollment information — serving utility, rate schedule and baseline territory — for you.

Calculated bills are typically returned within two business days of submission. If you are working against a tight deadline, email contactus@americansubmetering.com and we will expedite the batch.

The park owner is responsible for ensuring the accuracy of the data provided to us. That includes, but is not limited to, meter reads, tenant end-use designations, property elevation, baseline territory and any tenant medical or low-income discounts. The park owner is also responsible for confirming that tenant metering is accurate.

The full details of allocation and rate schedules applied and how the bill was calculated are included in the calculation detail. Email contactus@americansubmetering.com with the tenant and billing period in question. If a dispute is not resolved through this procedure, the tenant may submit a complaint to the state utility commission — in California, the Consumer Affairs Branch of the California Public Utilities Commission (CPUC).

Yes. We maintain the rate schedules, baseline quantities and seasonal changes for the utilities we support, so any calculation submitted after a rate change automatically uses the new rates. If a rate change lands mid-period, the calculation is prorated across the two rate periods. You do not need to update anything on your end.

When a commission orders a refund or credit that must be passed through to sub-metered tenants, we calculate each tenant's share and provide you with the allocation and instructions for applying it. Refund and credit calculations fall outside the normal billing cycle, so they are tracked and quoted separately from your regular per-bill fee.

The Bill Calculation Service returns finished bills for you to deliver however you like. For an added fee, we can print and mail bills, email them, and collect payment online through the tenant portal — see Mobile Home Park Utility Billing for the full service.
