GROUP: housing (ho)
DEFINITION: Human dwellings, includes enclosed & connected sealed or
compacted bare earth infrastructure (threshing floors, courtyards & outbuildings)
& interior vegetation (<5m). May include structures that are not in
use currently but that have >50% of roof intact (if less than this, see disturbed

- Object
- houses = human dwellings constructed as housing units with ground to roof separation
between households. May include detached houses, row houses, condominiums, and other
structures.
- residential apartment buildings = buildings constructed for multiple household occupation.
- housing-associated non-residential buildings = non-residential, non-garage, non-agricultural,
buildings associated with housing but detached from other hard features. These include
sheds, gazebos, and other housing-associated buildings that are routinely used by
those dwelling in nearby buildings. This does not include commercial or other structures
commonly accessed by people not dwelling nearby or owning the feature.
- housing-associated garage = structure used to store vehicles associated with housing
but detached from other hard features. This does not include garages built for apartment
buildings or commonly accessed by people not dwelling nearby or owning the feature.
- Modifier 1 (buildings in feature)
- detached = housing and associated infrastructure, separated from other houses and
courtyards by >5m of non-housing features. A single feature should contain only those
buildings shared by a single household (household defined as sharing a single cooking
facility, and shared land).
- shared wall or courtyard = houses, outbuildings and sealed or compacted bare earth
courtyards connected into a single feature: NOT separated by >5m of non-housing
features. A single feature should contain dwellings of more than one household (household
defined as sharing a single cooking facility and (shared land).
- Modifier 2 (structure type)
- houses
- single story
- multi-story
- Scale
- residential apartment buildings
- small < 30m
- large > 30m

- IF TYPE with greater area is very similar or otherwise unclear:
- Choose residential apartment buildings over houses over housing-associated uninhabitable
buildings over housing-associated garage.
- Choose residential apartment buildings over houses over housing-associated uninhabitable
buildings over housing-associated garage.
- Choose multi-story over single story
- IF it is unclear whether the size of a parking lot that adjoins or encircles other
builtup/building features is large enough to map and classify as a separate feature
(area is similar to 30m, 1000m2),then map and classify it as a separate os08 parking
lot feature.
