Document Abstract
The primary method for creating a population of homes from which to derive a random sample, as explained in the methodology, is to contact sample jurisdictions to obtain lists of homes. These lists are then sorted randomly to fulfill the sample. While this method has had success, it is not always possible to obtain a list of permits from a jurisdiction. In addition, even when permit data is available directly through a jurisdiction, it can be difficult to ascertain information on the construction status of sample homes. Knowing the phase of construction can be used to inform the timing of site visits to improve data collection efficiency.
For these reasons, alternative or supplemental methods of creating a home population for random sampling may be necessary. Alternative methods that may be used to build a list of recently permitted homes include target searches using jurisdictional inspection schedules, online real estate services, and general internet searches. The same alternative sources of data used to generate the population of homes may also help in scheduling site visits to arrive during phases of construction that maximize the number of observations per site visit.
