The Problem Mixed-Use Meters Create

Most apartment properties have at least one meter that does not serve a single clearly defined function. The most common situation is a leasing office wired to a panel that also serves hallways, common-area HVAC, or exterior lighting. The panel is one meter. The meter serves two things: an office and a residential common area.

Texas law exempts residential electricity from the 6.25 percent state sales tax. Commercial use is not exempt. A pure common-area meter -- serving only hallways, pool equipment, laundry facilities, or parking garages -- is a straightforward exempt account. A pure leasing office meter serving only the office is a straightforward taxable account.

The mixed-use meter is neither. And this is where most property owners either give up on the exemption for that meter or skip the analysis altogether because it feels complicated. Both outcomes cost money. The question of which use dominates is answerable, and when residential use dominates, the entire meter qualifies.

How Texas Law Handles the Determination

Texas law does not split a meter proportionally. If the residential use of electricity from a given meter is the dominant use, the full meter qualifies for the exemption. Not a prorated share. Not a residential-only fraction. The full account.

This matters because proportional treatment would produce small credits on leasing-office-adjacent meters and make the analysis barely worth the effort. Dominant-use treatment means the exemption is all-or-nothing per meter, which makes the analysis meaningful when the numbers are on your side.

The analysis is use-based, not square-footage-based. The question is not whether the residential common areas take up more floor space than the office. The question is whether the residential common areas draw more electricity from the shared meter than the commercial use does. Lighting, HVAC, and equipment load are the relevant variables.

What the Analysis Involves

Establishing the dominant use of a mixed-use meter requires documentation of what the meter actually powers and a reasonable calculation of the electricity drawn by each use category.

For a meter serving a leasing office that occupies 500 square feet of a building where the same panel also serves 20,000 square feet of hallways, common corridors, and parking garage lighting -- the residential use is going to dominate by a large margin. The analysis is straightforward. The leasing office load is a fraction of the total load on that panel.

For a meter serving a larger leasing pavilion with its own HVAC system, a lobby, and a conference room -- and also serving exterior lighting and a mail room -- the analysis requires more care. The leasing pavilion HVAC is a significant load. It may or may not dominate the residential common-area loads depending on the specific configuration.

The documentation for the analysis includes a description of each load served by the meter and either actual kWh consumption data by use category (if available from submetering) or a reasonable engineering estimate based on the equipment inventory and run hours. For most properties, the analysis is a one-time document, not an ongoing measurement exercise.

When the Analysis Favors the Exemption

On most Texas apartment properties, the pattern is the same. The leasing office is a relatively small load. It is air-conditioned, lit, and powered during business hours. The residential common areas -- hallways, stairwells, pool equipment, parking garages, mail rooms, amenity areas -- are running continuously and represent a much larger aggregate load.

When the residential use exceeds the commercial use, the entire meter qualifies for the exemption. The 6.25 percent state sales tax is removed from the entire meter going forward. The four-year lookback applies to the entire meter's billing history, not a prorated share.

This is why the analysis is worth doing even when the situation looks complicated. A mixed-use meter that initially looks like a partial exemption at best can turn out to be a full exemption once the actual load breakdown is established.

When the Analysis Does Not Favor the Exemption

The leasing office meter situation is the most common mixed-use scenario, but it is not the only one. Some properties have meters serving retail spaces, gyms open to the public, parking facilities shared with commercial neighbors, or commercial tenants on the same panel as common-area equipment. These configurations require the same dominant-use analysis, but the outcome is less predictable.

When commercial use dominates, the meter does not qualify. The analysis still needs to be done to confirm that conclusion, but the result is that the meter is taxable and the owner should focus the refund claim on meters where the analysis is more favorable.

The goal is not to maximize the number of meters claimed. The goal is to claim the meters that legitimately qualify and to support those claims accurately. Overstating the exemption creates risk at the Comptroller review stage. The analysis has to be honest about which use actually dominates.

What PowerCord Does With This Analysis

PowerCord handles the use analysis as part of the Tax Recapture process. After the owner signs the two initial documents, PowerCord reviews the meter inventory for each property and identifies which accounts are pure common-area, which are pure commercial, and which are mixed. For mixed meters, PowerCord prepares the use analysis in coordination with the property owner and uses it to support the refund claim submission to the Texas Comptroller.

The owner's involvement in the analysis is typically limited to answering questions about how specific spaces and panels are configured. PowerCord prepares the documentation. The analysis is included in the claim package submitted to the Comptroller.

If you want to see the overall estimate for your property before getting into meter-by-meter analysis, the calculator at powercordenergy.com/tax-recapture produces a four-year estimate based on monthly common-area electricity spend. It is a starting point, not the final claim calculation, but it shows whether the total is meaningful before any further commitment.
