For Chile, Instituto Nacional de Estadisticas (INE) publishes data on construction permits and authorizations at the national level. The number of construction permits submitted per month is reported for both residential and non-residential premises. Authorized construction permits measure the total authorized area (square meters) on a monthly basis.
Categories 1, 2 and 3 of a building will be determined through a questionnaire that assesses the positive attributes that has a construction. In determining the attributes, incorporation of new technologies and building materials is considered and may update the classification criteria.
Residential premises include isolated houses and apartments. Non-residential premises (industry, commerce, and financial establishments) include buildings designed for agrucultural production, exploitation of mines and quarries, manufacturing, wholesale and retail trade, transportation, communications, and other places not intended for dwelling.
The Directorate of Municipal Works receives building permit forms directry from the arhitect or engineer requesting the project. Each month, the data is sent directly to the INE for statistical analysis.
For the count of residential new construction permits, we seasonally adjust using the U.S. Census Bureau's X-13 ARIMA program.
