How Big is a Monster Home?


How big is a Monster Home and what's the average size of a typical new single-family dwelling in Honolulu? To help answer this question, this post did some quick number crunching (data.honolulu.gov) and finds that the median size of the 12,617 newly built single-family homes built between 2005 to mid 2017, is 2,344 sq ft


To conduct this analysis, a representative sample of 25 homes were randomly selected from the entire list of 12,617 homes. Of the 25 homes studied, the largest was a 7,211 sq ft home in Kahala and the smallest was a 1,462 sq ft home in Waianae. Of these homes, 18 of 25 contained floor areas between 1,462 to 2,862 sq ft -- see histogram chart.  

Floor area is only a starting point for further discussion and should not be taken as a definitive. For example, depending on the City Plans Examiner and Architect, carports and garages can be included or excluded from total floor area calculations. Other factors such as total lot coverage and open space provided affect the visual appeal and residential character of a home. 

Notes on the Analaysis:
Based on data.honolulu.gov, there were 12,617 new single-family structures built between 1/1/2005 to 6/30/2017. Filter criteria used: 1) New Building = Y, 2) Occupancygroupassed=01-Single Family, and 3) a new field was created: IssueYr, and filtered results include only 2005 to 2017. Google random number generator was used to randomly select 25 of the 12,617 permits. These permits were then manually entered into the Dept of Planning and Permitting's website to identify new floor area of these new homes. The table below was then sorted by year issued. Based on a population of 12,617, a sample size of 25 with a confidence level of 80%, would have a Margin of Error of 13.
