1 Single house - This is an independent structure intended for one household separated by open space or walls from all other structures. It includes the so-called "nipa hut" or a small house that is built as a more or less permanent housing unit or a "barong-barong" made of salvaged/makeshift/improvised materials.
2 Duplex - This is a structure intended for two house- holds, with complete living facilities for each. It is divided vertically or horizontally into two separate housing units which are usually identical.
3 Multi-unit residential (3 or more units) - This is a building intended for residential use only, consisting of 3 or more housing units. These houses may consist of one or more storeys in a row of three or more housing units, separated from each other by walls extending
from the ground to the roof or a building having floors to accommodate three or more housing units.
Examples:
a. Apartment Building - a structure usually of several stories, made up of three or more independent entrances from internal halls or courts. An apartment has one common entrance from the outside.
b. Accesoria - a one or two-floor structure divided into three or more housing units, each housing unit having its own separate entrance from the outside. Another name for accesoria is row house.
c. Residential Condominium -a high-rise building where the housing units are owned individually but the land and other areas and facilities are owned in common.
NOTE: A building that was originally constructed as a single house or duplex, but now partitioned into three or more rooms/groups of rooms (with separate entrance from a common hall or passage) without changing the outside structure or appearance, will be classified as a single house or a duplex, as the case may be.
4 Commercial/Industrial/Agricultural: office, factory, rice mill, barn, etc. - These buildings are not intended mainly for human habitation but used as living quarters of households at the time of the census.
A commercial building is a building built for transacting business or for rendering professional services, such as a store, office, warehouse, rice mill, etc.
An industrial building is a building built for processing, assembling, fabricating, finishing, manufacturing or packaging operations, such as a factory or a plant.
An agricultural building is any structure built for agricultural purposes, such as a barn, stable, poultry house, granary, etc.
5 Institutional living quarters: hotel, lodging house, dormitory, hospital, convent, school, penal institution, refugee camp, military camp, etc. - Hotels, motels, inns, boarding houses, dormitories, pensions and lodging houses fall within this category. This group comprises permanent structures which provide lodging and/or meals on fee basis. Institutional buildings are buildings intended for persons confined to receive medical, charitable or other care/treatment such as hospital and orphanages, for persons detained such as jails and penal colonies, and other buildings like convents, school dormitories, etc.
Also included in this category are camps which are defined sets of premises originally intended for the temporary accommodation of persons with common activities or interests like military camps, and other camps established for the housing of workers in mining, agriculture, public works or other types of enterprises.
6 Other housing units: natural shelter, boat, etc. - This refers to living quarters which are not intended for human habitation nor located in permanent buildings but which are nevertheless, used as living quarters at the time of the census. Caves, old railroad cars, other natural shelters and mobile housing units such as trailer, barge, cart, boat, etc., fall within this category.
NOTE: When a building is intended partly for residential purposes and partly for commercial or industrial purposes,
report as residential (code 1, 2, or 3 ) if half or more of the building is residential. Thus, if the ground floor of a two- storey building is for business establishments and the second floor for housing, the building should be classified as residential. Likewise, if a one- storey building is divided into several units, and the front part of each unit is for business purposes and the back part is for living quarters, also report the building as residential.
