When a resident vacates an apartment and another resident moves in, the utility company will only release the information for the current resident. Even if the apartment was vacant for only a few days, we may not have 10 months of usage for the new resident. How do O/As handle that?

In years when UA baseline calculations are anticipated, make every effort to collect information for the vacating resident prior to their departure. Ten months of utility data is needed for the same unit, but a change of resident during data collection does not impact the analysis. In other words, O/As could have 5 months of utility data for one resident and 5 months for another resident in a baseline analysis. If O/As cannot obtain the information for at least 10 months, O/As should not use the unit in the sample.
