LICENSED RESIDENTIAL BUILDER SURVEY
The Licensed Residential Builder Survey is a province- wide quantitative survey covering the typical builder 16 profile (industry experience, type of builder), their construction activities, and their satisfaction and perceptions related to research and education projects. The survey was conducted in odd years between 2003 and 2011 and every year between 2012 and 2020. For the 2020 survey, a list of 8,014 builders in B.C. was provided. Email invitations to the survey were sent out to 6,429 builders who were in good standing and did not have an expired, suspended, or cancelled license. Three reminder emails were sent on: (1) November 4, 2020, (2) November 18, 2020, and (3) December 11, 2020 to those builders who had not yet completed the survey at the stated dates. Phone and text reminders were made between November 25 and December 8, 2020 to those builders who had not yet completed the survey. There were 14 builders who elected to complete the survey over the telephone with an interviewer at that time. A total of 1,291 surveys were completed online by the builders, representing a response rate of 20.1%.
To ensure the final sample of builders accurately reflected the total population and composition of B.C. builders, mathematical weights were applied based on region (for example, the area of B.C. where they primarily build) and the number of homes built or started in the past year. The following table shows the original unweighted sample sizes for these two factors, the actual proportions needed, and the final weighted sample sizes.
