Technical Notes on Construction Statistics
CONSTRUCTION STATISTICS FROM APPROVED BUILDING PERMITS
Scope and Coverage
Construction statistics from approved building permits relate to administrative-based data on new constructions and additions, alterations and repairs of existing residential and non-residential buildings and other structures proposed to be constructed in all cities/municipalities of the country in a specific period.
Sources of Information
Construction statistics are compiled by the Philippine Statistics Authority (PSA) from the copies of original application forms of approved building permits as well as from the demolition and fencing permits collected every month by PSA field personnel from the Offices of Local Building Officials (LBOs) nationwide.
- Data on building constructions refer to those approved applications during the reference period and not to construction work completed during the reference period.
- The completeness of the number of building permits collected relies on the approval of applications filed with the LBOs. Hence, private building constructions without approved building permits are excluded in the tabulation of data.
Building constructions are classified and presented by geographic area using the Philippine Standard Geographic Classification (PSGC) as of December 2017. The PSGC contains the latest updates on the official number of regions, provinces, cities, municipalities and barangays in the Philippines.
Construction statistics utilizes the 2009 Philippine Standard Industrial Classification (PSIC) to identify the industrial classification of the structure proposed for construction through its use or character of occupancy.
The number of building permit forms accomplished by the applicant comes in five (5) copies. The “NSO copy” of the approved building permit is made available within the first five (5) working days after each reference month. Collections of these documents from the LBO under a certain city/municipality are undertaken by PSA field personnel within this period.
Collected documents for each month are properly checked as to its completeness by verifying the beginning and ending numbers indicated in the permit numbers. Missing numbers are indicated, with corresponding reasons, in the transmittal. In cases where there is no construction in a given month in a municipality, a certification that there was no approved building permit during the reference period is provided by the LBO to the PSA field staff.
Copies of documents collected from the offices of LBOs are properly controlled, sorted, edited and coded, folioed and encoded in the PSA provincial offices. Collected approved building permits undergo manual and machine processing both at the Central Office (CO) and Field Office (FO). The collected documents are kept at the FO while data files are forwarded to CO.
Manual processing includes receipt and control, editing and coding while machine processing includes data encoding, data merging, data validation and generation of statistical tables. Both the CO and FO utilize the Building Permit Computer System (BPCS) for machine processing of documents. The CO is responsible for validation, consolidation and generation of preliminary tables. During machine validation, inconsistent and invalid entries which are flagged in an error listing are corrected in the data file.
Data files received after the cut-off dates of submission set for each quarter are included in the generation of annual tables. Preliminary results are based from data files that have undergone data processing in the provincial offices and have been validated at the CO. The preliminary tables are revised to include building permit documents received after the cut-off period in the annual tabulation.
Construction statistics generated from approved building permits provide monthly administrative-based data on building construction at the municipality level nationwide. Statistics generated are the following:
- floor area
- type of construction
- value of construction
The statistical tables are presented at the regional and provincial levels by type of construction and by period according to form of ownership.
Aside from the preliminary tables posted in the PSA website, annual, quarterly and monthly statistical tables at the municipality level by type of construction and by form of ownership are available at the Industry Statistics Division (ISD) under the Economic Sector Statistics Service (ESSS) of the PSA.
Other special tabulations may also be made available upon request, addressed to the Undersecretary, National Statistician and Civil Registrar General, Philippine Statistics Authority, 2nd Floor PSA-Tam Building PSA Complex, East Avenue, Diliman, Quezon City.
Preliminary and final results of construction statistics generated from approved building permits are made public in the form of Quarterly Special Releases posted in the PSA website (www.psa.gov.ph) 60 days after the reference quarter and Annual Special Release, eight months after the reference year, respectively. The Quarterly Special Releases are reports containing the preliminary results of construction statistics generated 60 days after the reference quarter while the Annual Special Release is a consolidated report of the quarterly preliminary data incorporating documents which are submitted after the cut-off dates for each quarter.
Definition of Terms (Adopted from the Revised and Updated IRR of the National Building Code)
Building permit is a written authorization granted by the LBO to an applicant allowing him to proceed with the construction of a specific project after plans, specifications and other pertinent documents have been found to be in conformity with the National Building Code (PD 1096).

Construction refers to all on-site work done from site preparation, excavation, foundation, assembly of all the components and installation of utilities, machineries and equipment of buildings/structures.
Residential building is a building for which its major parts or more than half of its gross floor area is built for dwelling purposes. This type of building can be of the single type, duplex, an apartment and/or accessoria and residential condominium.
Single house is a complete structure intended for a single family or household, i.e. bungalow, 2-storey house, nipa hut.
Duplex house is a structure intended for two households, with complete living facilities for each; it is a single structure divided into two dwelling units by a wall extending from the floor to the ceiling.

Accesoria is a one or two-floor structure divided into several dwelling units, each dwelling unit having its own separate entrance from the outside.
Residential condominium is a structure, usually of several storeys, consisting of multiple dwelling units.
Other residential construction consists of school or company staff houses, living quarters for drivers and maids, and guardhouses.
Non-residential building includes commercial, industrial, agricultural and institutional buildings.
Commercial buildings refer to office buildings and all buildings which are intended for use primarily in wholesale, retail and service trades; i.e. stores, hotels, restaurants, banks, disco houses, etc.
