To measure the effect of school zone on housing cost, Linear Regression Model is widely used, and school zone is known as a key determinant of housing cost in Korea. However, when the Hierarchical Linear Model (HLM) is applied with the same data, school effect on housing cost becomes statistically non-significant. It is because HLM effectively separates the effect of individual housing's attributes from the group effect. In sum, the housing cost of Kangnam, where good public schools are located, is apparently is higher than that of Kangbuk. However, the school effect on housing cost (Level 2) becomes non-significant when individual housing's attributes (Level 1) are controlled with HLM.

The housing policy of Korea has been focused on the expansion of housing construction so far. However, actual support for low-income households is still insufficient, especially in public rental housing. The purpose of this study was to identify various methods of reducing the housing cost burden of residents in public rental housing, focused on empowerment. For this, 198 management staff of public rental housing under Korea Housing Management were surveyed using questionnaire distributed by email during February 18 to 27. Several ways to reduce housing cost burden and to enhance the self-support will of residents in public rental housing were suggested as follows: development of education and service program inspiring the residents' empowerment, enacting a provision of Tenants Representative obligation in Rental Housing Act, and so on.

The multifamily housing has various advantages in construction cost, land-use intensity. KRIHS(1997) recommended the proper scale of th multifamily housing as 800 households in constructability, 1,000 households in facility compactability, 500 households in social aspect. At the early planning stage of project, the size of the multiftmily housing has, until now, been maximizingly considered under the regulation on which has been emphasized at the building volume ratio, land area, etc., except for the expenditure during the maintenance stage. This paper aimed at providing the proper size of multifamily housing in aspect of area and household number with maintenance cost at the early stage of project. For these, it took 곧 average cost function which is made from the 3-rd quardratic form and analyzes the unit increasing rate of the average cost. It surveyed in nationwide focused on the central heating system using diesel and kerosene. The number of samples is 88 and items of management cost is 11. The results are as follows ; first, 3rd-order quadratic function is proper at explaining the cost variation, considering the multicollinearity and statistics. Second, the proper size of multifamily housing is recommended with 83,000 $m^2$ on management area, 820 or over the 2,630 household number in aspect of total management cost.

Construction projects, including housing, are carried out over long periods of time. According to changes to the construction period, the cost of input materials and wages also changes. Therefore appropriate management is important in order to minimize cost risks caused by fluctuations in prices. In Korea, housing units are usually sold in lots prior to construction completion. Therefore, careful management of input elements such as materials and equipment that are sensitive to price fluctuations is very important. This study deals with how the price fluctuation of materials, labor, and equipment influences the change of housing cost and seeks a way for cost management through identifying key resources sensitive to price fluctuation. As a result, a change to the housing cost index multiplies depending on cost changes of materials and labor together. Labor costs are a major factor on the housing cost index. In addition, certain types of materials and labor input to housing construction greatly influence price fluctuations. Thus, it is found that managing those main cost factors is the key for effective cost management.

The purpose of this study was to explore housing characteristics of young single- or two-person households in the U.S. metropolitan urban areas and determinants of their housing cost burden. Total 764 single-person households, 744 two-person households and 424 households with three or more persons were selected from the 2011 American Housing Survey public-use microdata for the study based on specific sampling criteria. The major findings are as follows: (1) In comparisons with larger households, single- or two-person households were characterized to be headed by younger householders, to have less income, and to have a greater proportion of households living in central cities of metropolitan areas, renting housing units, living in smaller size units or multifamily structures; (3) housing cost of single- or two-person households were significantly less than a larger households while housing costs per unit square footage (SQFT) of single- or two-person households was significantly greater; (4) regardless of the household size, there are many household headed by young college graduates paying too much of their income for housing, and single-person households were found to have the greatest housing cost burden; and (5) a linear combination of low-income status, monthly housing costs per unit SQFT, annual household income, and unit SQFT per person was found to be most efficient to predict single- or two-person households with housing cost burden.

For the quality of life and independent living of the disabled, government has provided financial supports for housing renovation and improvement projects for the disabled. However, there is a limited budget which should be properly distributed for a number of disabled families. Therefore, it is important to decide which parts should be improved for housing renovation for the disabled. Financial and administrative supports for the renovation should improve housing conditions in terms of accessibility (barrier free) and should bring the better comfort for the disabled. The purpose of this study was to describe the characteristics of the housing renovation projects, to investigate whether the renovation influence occupants' satisfaction, and to examine which factor such as renovation cost and renovation elements would influence the degree of satisfaction for residents with disabilities. Participants of this study are limited to the recipients of financial supports for housing renovation and refurbishment from City of Seoul and Ministry of Health and Welfare. A total of 153 cases were analyzed using post occupancy survey and the project cost data for the participants' housing were collected. Overall, more cost were used for modification for housing condition than for removal of architectural barriers. Housing type and physical condition of the housing affects cost for renovation more significantly. Overall the improvement cost is positively related to resident's satisfaction using regression analysis. In addition, it is important to meet the residents specific needs for repair, refurbishment, and renovation of housing.

This study examined housing costs and housing affordability of young college graduate renters in the Capital Region of Korea using microdata of the 2012 Korea Housing Survey (KHS). A licensed microdata set of 2012 KHS was obtained on September 29, 2012 from the official KHS Website and analyzed statistically. I selected 93,795 young college graduate renters between 20 and 29 years of age in the Capital Region and compared their housing costs across income levels and tenure type. Major findings were as follows: (1) Jeon-se deposit was on average 3.1 times the annual household income and monthly renters' deposit was 7.1 times the monthly household income; (2) households in higher income groups tended to pay a larger deposit and/or monthly rent; however, households with a lower income were found to pay a greater proportion of income to housing costs than households with a relatively higher income; (3) a total of 64% of all young college graduate renters had housing cost burdens to pay 30% or more of their income for housing, and more than 78% of the low-income households were found burdened; and (4) after housing cost payments, low-income households had less than one million KRW left to spend on other needs and savings; in addition, some low-to mid-income households had zero or even minus income left after housing cost payments.

This study explored housing situation and expectations of young (age between 20 and 34 years) single-person Jeon-se renters and monthly renters with deposit in relation with their family support and own housing cost burden status. Major findings from the analysis of 1,695,729 households were as follows: (1) Among subjects, 27.4% received family supports to pay their rent deposit, and 39.4% had more 'own housing cost burdens' to have housing costs minus the amount supported by their family be 30% or more of their income. (2) More than 11% were found to be 'more burdened' despite receipt of family supports. (3) Family support status was found to be related to formation of first-time households and tenure changes, while own housing cost burden was found to be related to current housing situation and previous and next housing size changes. (4) Households received family supports showed a greater proportion of first-time households or households experienced tenure upgrades. (5) 'Less burdened' households tended to expect housing size upgrade in their next move more positively. Based on the study findings, it was suggested to extend supply of rental housing and housing subsidy targeting young renters in conjunction with programs to encourage their savings.

Many attention have been paid to the innovative technologies aiming at the paradigm shift such as the modular housing, pre-fabrication method, or long-life housing. Despite the government's efforts to diffuse the long-life housing, few case gained the high grades by applying various technologies required in the Long-life Housing Certification System. The concerns of cost increase and low profit are the main reason why most of the construction firms avoid the adoption of long-life housing. In this study, the variations of construction costs were analyzed according to the grades in the Long-life Housing Certification System. The results of this study will help the decision makers find the optimal solution in employing the long-life housing technologies during planning.
