Conclusions and Limitations:
The initial analysis' results were not significant enough to consider permit issuance as a reliable predictor for building violations complaints. The assumption according to which higher number of permits issued will result in less building violation complaints did not approved in this research. Even when dividing the data into two sub samples of Manhattan and Brooklyn, there was no consistency detected in the behaviour of the variables nor their relationship.
One limitation of this research is the use of 311 complaints regarding building violations as representative for actual building / use violations, which are not compliant. Furthermore, as discussed in the data section, it is hard to assess the willingness to complaint about citizens issues across the city. Further work could analyze DOB approved violations rather that 311 data.
Another possibly powerful approach that could have made this study more accurate is to assess the housing units-per-permit, and by this to weight the affect of each permit on the city as a whole. This could prevent areas with single family houses such as Staten Island to be mistakenly revealed as significantly renewing areas.
Also, spatial autocorrelation tests such as Global and local Moran's I should be included in further research for all considered variables.
To conclude, renter/owner occupancy percentage has some predictive power of building violations 311 complaints, as opposed to permit issuance as was analyzed in this study.
