Housing Overhang Summary Data
17
The following data sheets support assessments done in June 2011 to discuss Idaho's "housing Overhang." A Powerpoint Presentation on this Website entitled " Idaho Housing Market Fundamentals" by Brian Greber is based upon this data. That presentation includes the following definitions: •A housing unit is a house, an apartment, a mobile home, a group of rooms, or a single room that is occupied (or if vacant, is intended for occupancy) as separate living quarters. Separate living quarters are those in which the occupants live and eat separately from any other persons in the building and which have direct access from the outside of the building or through a common hall. •A household includes all the persons who occupy a housing unit. A housing unit is a house, an apartment, a mobile home, a group of rooms, or a single room that is occupied (or if vacant, is intended for occupancy) as separate living quarters. Separate living quarters are those in which the occupants live and eat separately from any other persons in the building and which have direct access from the outside of the building or through a common hall. The occupants may be a single family, one person living alone, two or more families living together, or any other group of related or unrelated persons who share living arrangements. (People not living in households are classified as living in group quarters.) •Building permits represent the number of new housing units authorized by building permits in the United States. The building permits data relate to new private housing units intended for occupancy on a housekeeping basis. They exclude mobile homes (trailers), hotels, motels, and group residential structures, such as nursing homes and college dormitories. They also exclude conversions of and alterations to existing buildings. –These are typically referred to as “housing starts” •The homeowner vacancy rate is the proportion of the homeowner inventory that is vacant “for sale.” It is computed by dividing the total number of vacant units “for sale only” by the sum of owner-occupied units,vacant units that are “for sale only,” and vacant units that have been sold but not yet occupied; and then multiplying by 100.

Transcript of Housing Overhang Summary Data
The following data sheets support assessments done in June 2011 to discuss Idaho's "housing Overhang."
A Powerpoint Presentation on this Website entitled " Idaho Housing Market Fundamentals" by Brian Greber is
based upon this data.
That presentation includes the following definitions:
•A housing unit is a house, an apartment, a mobile home, a group of rooms, or a single room that is occupied (or if vacant, is intended for
occupancy) as separate living quarters. Separate living quarters are those in which the occupants live and eat separately from any other persons
in the building and which have direct access from the outside of the building or through a common hall.
•A household includes all the persons who occupy a housing unit. A housing unit is a house, an apartment, a mobile home, a group of rooms,
or a single room that is occupied (or if vacant, is intended for occupancy) as separate living quarters. Separate living quarters are those in which
the occupants live and eat separately from any other persons in the building and which have direct access from the outside of the building or
through a common hall. The occupants may be a single family, one person living alone, two or more families living together, or any other group
of related or unrelated persons who share living arrangements. (People not living in households are classified as living in group quarters.)
•Building permits represent the number of new housing units authorized by building permits in the United States. The building permits data
relate to new private housing units intended for occupancy on a housekeeping basis. They exclude mobile homes (trailers), hotels, motels, and
group residential structures, such as nursing homes and college dormitories. They also exclude conversions of and alterations to existing
buildings.
–These are typically referred to as “housing starts”
•The homeowner vacancy rate is the proportion of the homeowner inventory that is vacant “for sale.” It is computed by dividing the total
number of vacant units “for sale only” by the sum of owner-occupied units,vacant units that are “for sale only,” and vacant units that have been
sold but not yet occupied; and then multiplying by 100.
